HappyHakoween: Password Cracking Clusters, Remote Control Services, Wireshark Packet Filtering

Wednesday, October 29th, 2008 – running time 45:10
Matt shows us how to turn anything into a service and provide a web frontend to manage them windows server, great for game server administration. Chris Gerling wraps up his three part series on Packet Sniffing with Wireshark techniques for packet filtering. Darren harnesses the CPU power of the HakHouse for good or evil to demonstrate cluster computing. Plus details on our Hak5 Halloween LAN Party!

Matt Lestock turns any windows application into a service using instsrv and srvany and demonstrates how we use this technique, coupled with Panel Daemon to delegate game server administration at the Hak5 playground.

Chris Gerling shows us some packet filtering techniques using the network analyzer Wireshark. He covers capture filters, display filters, colors and statistics. Read more on packet sniffing on his blog at ChrisGerling.com

Darren Kitchen talks about parallel computing. He touches on grid computing and massively parallel processors though he mainly focuses on clustering. Darren demonstrates simple windows password cracking techniques using an openMosix based image and discusses the theory behind setup. Darren has a lot of further reading for you to check out on his blog and would like to hear your feedback about building the Hak5 beowulf cluster!

And on a production note: We've switched over from a standard-def composite based video mixing solution to a high-def HDMI based system. Unfortunately until we get a Mac Pro and switch to Final Cut Pro for editing we're unable to release a 720p version of Hak5. But we're well on our way to bringing you guys truly high def technolust thanks to everyone who has continued to support this cause. Thanks!

" War. Yeah this week Halloween. -- I've been brought to you guys godaddy.com. Netflix dot com. Square space. And talking balls. What about refusals."

" I don't know Hak5 it's time for your week he -- technolust. I'm going to guess I'm -- less integration you get today we're -- Public service is clusters. Packet sniffing. Yet Chris early continue his three part segment on packets. There you. People clustering. Or even. I'm -- guy's service action. As always we've got or contribute segments. And we're totally rockin'. Out and got out the candy. Though that was good it was finally destroyed thirty pounds -- All it wasn't pretty there are pictures you will never be online take a look at -- she's -- Yeah. Anyway I think it's time to go ahead and take it off so let's and just go ahead and cut do you year. Record segment about services. It."

" Yeah so you may find yourself administering a server. And wondered yourself how can I managed services easier or gives somebody access to -- services on -- Before there was really never really easy way to do today show you how to create -- your customer service at your own custom services. Or actually in allied control services via the web. Using utilities both of which were which are free and of course we love free. The first. Utility is part of the windows resourceful kit which you guys can download -- Microsoft dot com. Links in the show notes as well. Part of but when he application package resourceful cable line you. To create your own customs services now there's a couple manual configuration things that need to happen before your -- actually become active. In good -- right now. Outlook we're gonna do his erection and create a Customs Service now lot of people think that creating services is a big myth and mystery and that it cannot be done. On its very easy once you download the -- we're gonna go Hindus ago and -- windows box. And when you downloads tool kit you're going to find. A new directory obviously place your system. I'm breast program files -- and browse to windows resource kits. And tools. And here you'll see all the schools that via the installer. Installed. On one of those being. Used. Sir I NS TS RB EXE. That is the key one that is the one it's actually going to allow us to create a service a -- around. You wrap your head around this for a second. The command I'm gonna show you is not the service that we actually want to create its launch or service there's two components to installing -- service there's instance her. In her. And there's also servant. SR VAN YE XE. These two components pull out create our own custom service however the command and show you right now he's not disturb that actually create. So the two components obviously being like -- for instance her eyes Willis service. And what I've gone ahead and done for making it easier to understand is we've gone ahead and copied serve any. Two weeks -- RC drive. I'm basically the command is as Klaus. I NS TS RV dot EXE. Or without the name of your Customs Service. And then wherever the serve any SR VA and -- program is -- on the machine it just happens -- happens to be an -- drive. Once we go ahead and run that. The service was successfully added and that's a good sign. Now you can't just go to the service has control panel and start your service because we haven't actually defined it yet fossil we need to do we need open up reg edit. Registry editor for windows. If you're not familiar with it. Probably want to be careful because you can serious abort system. Win you've actually run the taller. And creative your own service. What you will see in. The tree. A legal machine. System current control set services were actually going to find. Customer service which is what we just created the command line. Now we can actually set up our application. Inside this registry but first we need go ahead and add -- Entry to this so we're gonna go and do is click new and it's gonna be K we're gonna type in. Parameters. I actually get that spelled correctly. And still check machine correct it parameters. And we're going to create a new string. Being application now applications -- as was actually going to launch our service. And down here in new string value. And okay simplest. Go ahead and edit the application and we can type anything we want. -- Now what we go into the services and MC. What we should see -- as we should see our custom application. Our Customs Service so -- typing custom well that's not a Customs Service right here now we go to the properties of this. You'll see that the path to the executable is SRV Andy dot EXE. That's good. That's as I mentioned in the beginning the launcher application that is going to actually launch or custom application. Like a -- your head around the fact were not actually launching our program from. Server is command. And -- actually launching the launcher service which will then launch our program. Confusing now don't worry it's. So when now that we've actually created Customs Service let's show you how to manage that service via the web. The basic reason that we went ahead and we created. -- we needed to find a solution. So that our community members can manage our games servers that's where this whole process came about. That's where the entire need for Customs Service management via the web and services was created. If you go into. For example are CSS server here and parameters. You can see that we've got the applications strain. On camera numbers -- better power could somebody please throw me at brick. Max players 32 -- rates on so forth we now have the ability to sign users so that they can create their own customs services are excuse me. So that they can administer our insurers forest community project from by the community we also had FTP ability for them. But getting back to the services they can start and stop these service. For the game server at any time. And that's cool that we actually used to do that is penalty. Now some of you may know. Fire. Fighter game and being the service control software -- create automate. Whole kinda stuff with services we don't need that we don't need service automation we don't -- service monitoring if somebody detects the servers down. They had a valid login but. Wired and has created a front end for their application which they released -- open source penalty. Panel Damon is a really nice piece of software that -- is extension to act yes or. Com and allows you to view -- list of the current running or stop services on the box that counting all now remember. I guess or -- are prerequisites. For installing counting it. So if you're comfortable with having. Web service on here box for whatever reasons. -- On personally we don't have a problem with it because I guess the Apache the pretty -- down nowadays -- box updated. But. Here the users can actually hacked vice SS they can see if it's currently running -- it's not running in if they need to you. It connects the issue restarts for the applications. Now I'm not gonna get into installing a basic application you guys are obviously smart. The props are very easy selects port number select the virtual running. You know web application directory. -- just happens to be handled -- but you can mean anything one terror security securities -- Well bill files they'll FTP server is currently running start mode local. -- system auto you know all of this info is available. -- services and Nazi war via the website we can stop all the services we can star all the services and we can also limit. And -- in street guys who we actually have set up. And as administrators on our. Installation. These are your community. Game server Edmonds. This in those all -- Wiki darting notice but. So here. You've got people who have access to only specific services so when they log in panel. These are the only services -- they see. And these are the only service that role now is great for granular granular. Security commission's obviously we don't want. Complete access machines running on it not that you guys gonna do anything to it bought. It allows us to make sure that we have complete control over who has control of what. We normally have control over yet that makes sense. So panel Damon and serve any answer. All the links for the information will be in the show notes yeah asking go to Hak5 dot org or my website met last dot dot com. And now I think Shannon. He's going to. Rapper brings with some trivia and --"

" I this week's trivia it is. What vintage supercomputer was named after stream a raise in its speed and floating point operations per second. If you're the first one in this right and your choice of form whether it's packed -- or this entry we'll send you not only stickers. But also a parent opposes CD. And good at is our sponsor. -- reliable secure web hosting without a long term contract go -- hosting plans are bigger and better than ever with 99% up time. 3247. Support and no annual commitment plus you can register a dot CA don't mean day. As a Hak5 viewer you can get at 10% -- with AK one. And now we're gonna bring it over to christened with packets and."

" Are here we are with the third installment of the packet sniffing extravaganza -- will once again Chris -- Showing us how to actually get her hands dirty we understand high level stuff. How are packed together the lowest layers and it. Let's take a look at some packets an actual traffic."

" We'll be on the building blocks it was -- so we're gonna focus mainly on the wire shark. Program in this in this segment the businesses what we. -- use wires we're gonna go to some of the arrow functions not all of them but enough to go and get him you know aluminum or dangerous. -- without borders what this basically does it and we've kind of heard before leading really -- news exactly doing him. It will capture everything off of a given network network interface. And depending on what options and -- news so did ID call it just -- fire house it. Get our requests he did you know who has a -- interest who has this Mac address who you just get everything. GDP no matter what it is and."

" And again this is great for either debugging is a network administrator or even if -- man in the middle you've got somebody plowing through peace effort that you have access to it -- just watching everything in between exactly we -- that we don't want just want to see everything there's there's stuff that were interested and so you've come into it. What I'd like others what."

" Higher traffic yes we zero in this example you know we have a -- example so have an RC client up. Right here who's going to minimize it really quick camera and go back. -- spaces here. So this is just. This this -- Microsoft. Is this going to start. Now anything immediately you chronicle web browser -- yet if I did Hak5 industry fresh. And yet. Thousands of again there's no one big. -- don't see how small that scroll bar thing is right now its its -- 10096. Packets. Justin on its axis of the -- about it. Great so now we're going to who's gonna stop that one and restore. The Soviet analyst. And piracy here and reconnect. It's actually that there Eisner's. So now we're connected I'm gonna actually guys have a dummy element that's now hit that sit at -- summit message an excerpt. -- And that's thats me let's block. -- mind -- it's one of Africa and and then we're yeah we can do that we can message mixer. -- Release there right. Apparently it's okay. -- now go back here we see you really excited -- bargain. Hit the a lot of traffic and now we want to actually want to like -- this with SS DP it is a whole -- just. They tried strolled around and read it justice so much -- the ads is more than desires he likes expectations though. So we need to filter and this is an ominous stop its Morrissey it's actually. Work with 364 packets. I don't literally go through 364. -- and I'm looking for so what we devises. There's us. Of the musical character filters and also just real time to display display filters -- And so we differences. They capture filter will filtering out before before displays that don't -- Takes we already have so you -- if you. -- so we -- gonna do artsy request. That's the actual screens just -- industries. We're gonna -- contains. Mixer. So this is gonna tell us just everything out at the request is everything that Klein said everything as an -- announced so we can do both the server okay great so I -- for -- party yeah new -- partisan password Yahoo's response or we can responses or even his city public conversation that -- happening with the two people -- response from that person exactly okay so when I hit. And here we're down to treat packets. So all. You can pick and of course piracy is a small that we need to worry about and like path in to use size not to fragment. Yet so what the first packet. So our first -- is actually identified packet there's a password so it's through that's an ambulance. On this. Every gallery there -- cool little invented. And as. It. It's from a password don't use -- actually tried. So so you don't. If you didn't know before. He's not using encrypted you know plain text is just quit. Also remember that when you actually people who you have late user names on servers don't use passwords used -- important things. -- your banking password you know custom create a password that strong but that's you know its its self exam area okay great so we were able to filter just the next serves up. With the highlights the and and and okay so we can going here and right click on this one for example and we color this as well. So we can to stew and you caller all right this code. Creating -- made so now it's different. And you can do this -- rules. Yeah and you can actually go here I'll I'll open season you can look at. But this is where you can go through. And I have this because as we've. -- down that means cancel out of this and you -- see page created. Here's wonder created on your -- request contains Acer that's an ugly but when I think that it is like -- and asking."

" Everything and are -- are just looking to mixer passwords you wanted to sit back watch the whole train and and the lady in red dress comes by -- totally identify herself back in -- blue and red kind of ugly but at least get through to your attention. So. I -- color -- does it filters what are the concept can do with."

" We what do you statistics. And error. -- you agency years you can use statistics from just about any sort of packet. -- I mean it's just. Multi streams different things like -- VO I. VO I. Com you can look at that thumb one of the nice little things that I like to do is pull summary here maximize that. This just gives you a general overview of what happened during your conversation so. We captured a 164 packets. -- like three it just it tells you kind of how long it'll just you know it's a really nice little quick summary of what happened on we get out of that. We can pull this up again and I like to also -- conversations. That's a nice one that I like to."

" So if you're just watching a lot of people are multi chat and instant messengers going and it got -- Rezko and company get past that session. Some of the lots of different types of protocols going time. And we don't even know what we're looking because when you look at the fire is the -- to pull this like well here's what they're doing an iPod and."

" It has to concede there's a fibre channel I mean there's everything is you've got I PV six down here you mean yeah I PX you've got a token ring and so any kind of you know its its filters in South Korea so it's really easy it's just nice charts."

" Again yeah beautiful school. Kind of a lot of information will ruin do you down signal noise and it sees itself."

" Exactly so there's there's a lot more powerful things you can do I mean there's even a firewall -- here where you can actually. Generate -- Cisco violence rule based on."

" If that's that you of course right all of this and you find other resources coming up people. And new rules that hero -- expert and make your own filters and and they just -- addresses. Are right Chris excellent stuff as always. And it. Kick it over and it's dying it's week's party."

" I know Halloween is coming up and a couple of days and I don't know about you guys I'm super stoked coming from the spam -- come from. -- we have a -- paper by digit. An awesome I wanted to tell you guys about our Lan party coming up this Saturday November 1. You -- game died at five hour from the comfort of your own home you don't have to be in Virginia guys you know it's okay. Join us up there played a game -- Austin news. Which means probably can count if you don't really feel like playing in the game go to Hak5 dollar can check -- on the site can't. But for now we're gonna toss it over to the guys talking."

" That's right -- sponsoring the Hak5 Lan party and were excited to be working with them it turns out there in the back I've been watching since. Into this one X three it and edit and also to listen and I've been checking software a lot of fun to use it's like a desktop application but it's totally your browser. Blurs line their little bit between web and desktop."

" Yes square space meaning if yes -- looking to create any kind website or blog or list or anything that's sort square space you need check out. Not only do they have great publishing tools. In my opinion their tools and analytics. Rival. Google or you know you're web trends or anything like that."

" If you use something in the path that like online publishing tool like I don't know Google pages for example. You're getting the wrong idea of what publishing systems can really be like on the web. And he speak universal that that the people over -- face the developers who obviously we've talked to. If if you guys are you know trying to square space and you find that there's something that you don't like where you think should be added. Send us an email so that we can talk to them because they are super motivated and adding anything and everything they can possibly add. I know Kevin and Sarah from Revision 3 people -- requests were implemented in less than a week. Four there -- personal website."

" When he's trying to say is that's where space is basically at least four times cooler than last -- And CD's check out. In fact one of her very own illegal has even I checked -- towards -- and put together page about the Hak5. -- Lan party that's right we're gonna. On Halloween Lian contest then and that is only need to do is on Halloween once you've done for treating or maybe tool that up. Head over to log into that or UT's that -- that organ and an undetermined 99 in the old classics. We're gonna -- be playing countered to CSR five dot org and the battle have to I'm sorry team fortress team fortress -- dot time dot org wouldn't be having so much I'm I'm I'm probably a little bit. On the fences to win the game should plan on going to be in the UT server."

" The and I'm probably going to be an -- drawing the battlefield two server. Through my game but. In addition if you guys have a suggestion or Lan party please this up feedback I've dot org or forums. Or you can go to square space dot com and sign up for free trial and we want you guys Cory and you have five Lan party website. -- that square space dot com sign up for your free trial in addition you'll see the power and the you know capability that square space really offers a feel for you know if you. Use it. Like there's that word press is great but and somebody insure that your site is up percent of the time is our better."

" hey Don and plug it had no idea about when efforts apprentices like it was and it just watched that you on the home page and like. And instantly within a few seconds totally -- it. And of course Hak5 Halloween expert based on three confines -- put up all the details about our then it's Halloween and we hope you guys will join us. So anyway at this point we're gonna go ahead and talk about clustering so that it. Magically and -- snobs about all the fun so you can do it."

" And sound and has all hardware all. He's taken over the -- All the computers Apple -- Real he had real mom and the when he's he's tree hill and you. In particular. It's when you take a look at the hardware and use it -- spread the load -- instructions tasks so lots of hands and work. -- Talking about -- you. -- talking about multiple computers. Well in this instance -- department cluster computing where we use lots of individual computers each with -- operating system at all. Can birds and work -- time. It would work on things simultaneously in parallel we can do it faster. And it. My computer's politics. That we've done here is working me exactly lots little worker -- I need the of these is here and and -- system. And we. Altogether and use all the resources. Hopefully it instantly with a closer. -- excellent -- some other types of arrow keys and there are. On. Well there's massively parallel processing. Which is what you would see and things like. Earth simulator supercomputer. -- difference here is that all the components kind of come together and single machine rather than an author with L actually have their resource gotten. -- Yeah this is something that you that's a companion -- and of course accurate computing. Well are you familiar with -- now. That grid computing. Team Hak5 -- and he's folding home team and you can. -- processing power when your computer's idle screen saver. And starts using it to Apple proteins and -- cancer something like that and the difference there is that it's very loosely organized but only your system resources only join the grid. Win and they're available you know when you're not playing tenor and -- and back. And geographically dispersed so that's the difference between green computing there. Where -- it would be currently in our house -- No what I want to do is -- want to build a Beowulf cluster. It is actually named. -- ethical and epic -- There's actually the term came out nineteen and apps built. This has nothing -- call the Austin but then. Kind of became a general term. Senator with us I mean like imagine a Beowulf cluster that plans are now. Or whatever. But it's become -- generic term for. Yes and she Margaret and author. That's. -- in some examples. It."

" And you want to see an example -- ambulance some of the the systems that that you. So would have got here booted up is an instance. Cluster not X. Now clustered topics in open march 6 its system. And that support all I had. -- my six is a management system for providing -- side which is single system image and and it also allows for simple process migration so. For -- single system image. I'm all of this hardware this this -- here that keyboard and yet here's. All have to run this team at the same image here in this case it's cost optics. Could be a lot there's lots -- Linux distributions that do this. In this case through to season lets not X. And that's -- aside that's the single system image and I opened my six provides but that and the process migration. And that's really weird parallel computing kind of comes and by. Is that we've gotten we want to take something it split up into many processes as possible. So we can distribute the load alternate process you can process Mac and that process and process Paul and and all four of us."

" It break up Lego bricks and build a time capsule ninth Portland on faster. Oh hold hopefully four times faster than would the if we're all individually right. Yeah. Of course. That it's not always exactly four times and you'd think -- so freaking example like patchwork. If I can crack city paid 55 character password. We'll just say when isn't -- and in like four minutes with one computer. You think that idea what to do it into two minutes for cheap computers. One answer. Electric -- computers yet every time double we actually fastened to. Not exactly right there's there's a single -- law which talks about the way that the program is designed and the efficiency. That. That's there and it really talks about the bottlenecks of the design program. And it's a way for you kind of estimated age. What. What kind of of efficiencies you should expect for different programs when you actually do a multi processor. Or a parallel."

" scenario so are you saying that since we have different kinds of computers different kinds of CPUs. We won't get as much efficiency as we wait if we had three right now is the exact same computers."

" There's a lot more involved. With it than just see you while these are all three different systems running it different. Yeah different architectures because -- different companies. The ring at different speeds you've -- to denounce him. Not know the OS is exactly that's SSI again. He's insisting on it or running -- not picks up faster topics right now so that's. -- operating systems all things but they're there hardware differs vastly and even. You know that are just kind of idea and the -- network in this instance the network is kind of the bottleneck. Because it's 100 megabit network. Rather than the Gigabit and that's just the limitation of war which accounts that get them in bigger and plot it out let. Yes so. So that's that's different there. Of course it would run a lot more efficiently all the same hardware. But of that to factor into its -- actor instantly that it's the whatever is that we're doing multiple processes is is written so that's and the law. I guess that I -- an example here in Austin optics and would have loaded up here."

" lots of New York mafia is a open source. Alternative to mark six like to spokesman inconsistent yes -- process migration. And what do -- load up. And you can see right here we've got. Three different machines and we've got into it there's Iraqis we can see the room -- allude. And see their memory usage here is it -- some units in this instance of the three computers because one of them. -- So. That would be neat yeah. -- It's a proposed to cut the cord I don't know seriously. So I'm just show an example and there isn't any different reasons why you want to do -- be it all home rendering out. -- up our own view yeah rendering -- case about that. You know. Though. It's become a little. On the benchmark and it managers here as an example is -- Has yet. So -- that he would have got here. Path and dvd and you can see I've got a couple of patches here and these are just and he on -- Yeah from windows is going I just went -- which police one machines within DS passwords. Here's sensitive or anything. But. -- tendency here got my user account Aardwolf. Here and I can't go ahead run -- against say Katherine crack. And I'm just. You reports -- and -- and and it creek and he did anything like what aspirin factories and using this one that called yes. Totally that's opening here it's called to sell. -- art and that'd. And you could use to like them rapper but this is it makes it really easy to split up jobs and multiple processes. And then through process migration with the optics. That are all processors and split up and you'll see here runs going to go ahead run as you can -- you Hopkins and in the -- Customers -- Okay so. And run this command here it's -- So prologue test file North Korea here where do you attack and four that's how many process is ongoing on. And this of course have to use the file got from yeah. Song and split the four processes because again down here actually have four CPUs to use. Because they've got three computers multiple -- and run that. And I -- you can see also outlook. That that this machines and 91%. Because it's doing all of that at once and analysts and we -- And that's where the process migration I'm up in and exactly to -- hey guys we audit crap did you hear him just kind of pitches and hold it hopefully -- would all get 200%. On much past work force -- got -- here. But that's what I want to build something where everything's the same hardware and on another network unity color and it is so accurate it's already done. And you can see. -- user Aardwolf -- be the real simple and he'll eat well and so -- think -- I mean that's not really fast and -- is prepared passed between us here it was yeah it's got a dollar -- But they're that the one."

" On some of the collect on open -- prisoners and that we use that. And that's that's -- in case. You are important there's opened library. Pipeline the use -- basically speak all of the other computers and network and here they're cute they're an image. This work. And it. It's it's seeing. API it's not standard if you well. It's become a standard in the sense that it's active standard but only needed -- and accurately standards body. Specifications. Thoughts. Just like you that. Microsoft cluster server. And there's lots of experience and that we're actually going to be using. X later. This technology. Maker. -- Yeah and and it's -- On so I guess that's something we talk about he. I will cost. Something that we are really looking for you in on an ongoing project that we just start. And and older and Leo cluster. Based on whole. Idea is around you welcome your feedback. Kind of operating system outlook -- easy. And look at something like total force. And what substance that -- that. Basically once dialogue. This is something that we can build and Andy's segments on our software and hardware in this country. He. Doesn't have to -- he."

" It definitely is -- make an -- wooden box -- Mac or so do you have anything else that you tell us what this. Not really when it's give this demonstration. That's an underlying technologies businesses one of these products and -- and yeah. Different development a tungsten -- is there's links on the need for ways to use them and didn't hear from the audience like happy conclusion and all put together hardware and software and and -- some good rather than just cracking -- and that's coming -- today in that rainbow tables -- computed and and -- it. There's gonna it will this cool that you could use this to generate and tables uses to support. Did you rendering is one thing I'll do it. What's the difference between. What with rainbow tables and we've talked about in the past second season. The real quick and basic ideas time memory trade off. So in the sense that it took twenty minutes to crack at your password that was the time. Versus rent it causes memory where -- need to human -- how many case whole gigantic look up between us is what is equal. About it but yet at all. Leads that senate and in this isn't -- stuff that we did on. Some stuff that of course I should note that this is good -- all that stuff so he could use. That can actually. Handle that and and should let you got tons of computers this way around your house you know definitely try it out there's. No topix closed off topic this kind. And projects kind of dropped. And -- open mosques that lion and pelican. But there's also some other really cruel mistress it's one cause chaos in particular. That's worth noting because. When the university projects it was created about around the whole idea of I believe cossacks and what it does six megabits. Distribution which is perfect he got. When it is hoped I'd write it I have got 106 gig it is six meg C. Plus Q and -- It runs in memory -- about popping computer -- often entails. Would be up and then you do on the machines what happens is kind of ad hoc. Not like this is -- of like -- model and where is just an ad hoc developed a double -- to each other. In I act so it's encrypted links between each other and that's the kind of the cool part is once you've got that encrypted links and you could technically use it on. Semi trusted networks like universities. And I think -- but if you got a giant corporate network to do anything at night you could use these things. Harness that computing power for. Good evil mostly. So you're obviously. Show us how to do -- blogs yeah I've got links to -- the difference I mean who run long here. But it's a lot of and so it is there's a lot of I find really fascinating and the importance in the I think that's and then of course put together hack. Oh let's."

" So. Well thank you very much and in the weird payments and now. We're gonna -- great. Yes."

" Expenses are out of this episode before we get down when -- you know you have to tune in next week's episode because we've just come back from freaknik. On opposite -- account so next Wednesday. In the eastern check it out it's gonna rule -- guys know about is these stickers which are still for sale. You guys may have noticed that we've gone to a little higher resolution SD pupils Internet you've seen on the Internet. That's because that's how we roll. But however we are and not capable of releasing it because we can't edit Ph.D. footage yet turns out it's really high rate and our machine to discourage you can like. A euphemism -- can -- them up now if we how to Beowulf cluster Paulson us. Yeah that would be easier instead if we had knocked out and opt though Mac Pro so that's what we're currently. Striving for now people may think hey what the hell. I I thought this was that now we need this last component and it's trust me it's much cheaper than 50000 dollar mixer. Plus a Mac Pro we are currently. This close they were going through and -- more trying to look at capital or ram. But we -- aren't macro and in. And then gets its act five dot org slash stickers remember. Us."

" Yeah definitely and you get independently got a you know dispute lefty so when I think everybody. Out there and Dan and Europe and tickets still available would love support and more on the way more different designs. Fonts that and look forward to yeah. With the equipment indeed okay so I'd also like remind you guys that and Netflix is sponsoring this episode Hak5 and Netflix not only is awesome but they also how over 90000 titles include lots of Blu-ray titles. And with free shipping both ways you can get your movies on the type forty shipping centers almost the same day delivery or one business day you will. And their plans to start it 199. So check them out you get it -- no risk trial over at WWW very important www. Netflix dot com slash -- Five and again remember the WWW because somebody can't -- ready access. Regardless. -- he's in the wrote Netflix box partly the last annoying the crap out of the rest of these packed house people's because it has been watching a lot of documentaries about. Stealth fighters and let's just the X 35 is awesome and we're going to strike fighter but still -- documentary I'll have a list of I think it's not over identity dot net Poland and Netflix where sponsors."

" Ultimately you guys now iFanboy which is currently Revision 3 network Wednesday's. -- eastern. Or. Comment -- her -- You just love comic books that this is the show for you -- I mean this. Not so much for the kindness action but. A comic books on guys can go to revision3.com. Slash I. And remember. That check out their new episode with Brian and this writer of The Adventures of Superman US -- Excuse me for Marvel Comics and watch again I think Hamlet every Wednesday. Noon -- in that. -- And now prepare myself we're reminding you. --"

" Welcome to -- five this is. My second. And."

" I had before I. The only group report can't be -- Hey."

" edit it edit it. Next episode we'll be airing all of the happy stuff that we've been doing great. And it. Was that the and we agree would never be only if arts and -- RTL. We're about to lose. Hello and welcome to hacked by this time you -- that the typical -- What more important it."

" War. Yeah this week Halloween. -- I've been brought to you guys godaddy.com. Netflix dot com. Square space. And talking balls. What about refusals."

" I don't know Hak5 it's time for your week he -- technolust. I'm going to guess I'm -- less integration you get today we're -- Public service is clusters. Packet sniffing. Yet Chris early continue his three part segment on packets. There you. People clustering. Or even. I'm -- guy's service action. As always we've got or contribute segments. And we're totally rockin'. Out and got out the candy. Though that was good it was finally destroyed thirty pounds -- All it wasn't pretty there are pictures you will never be online take a look at -- she's -- Yeah. Anyway I think it's time to go ahead and take it off so let's and just go ahead and cut do you year. Record segment about services. It."

" Yeah so you may find yourself administering a server. And wondered yourself how can I managed services easier or gives somebody access to -- services on -- Before there was really never really easy way to do today show you how to create -- your customer service at your own custom services. Or actually in allied control services via the web. Using utilities both of which were which are free and of course we love free. The first. Utility is part of the windows resourceful kit which you guys can download -- Microsoft dot com. Links in the show notes as well. Part of but when he application package resourceful cable line you. To create your own customs services now there's a couple manual configuration things that need to happen before your -- actually become active. In good -- right now. Outlook we're gonna do his erection and create a Customs Service now lot of people think that creating services is a big myth and mystery and that it cannot be done. On its very easy once you download the -- we're gonna go Hindus ago and -- windows box. And when you downloads tool kit you're going to find. A new directory obviously place your system. I'm breast program files -- and browse to windows resource kits. And tools. And here you'll see all the schools that via the installer. Installed. On one of those being. Used. Sir I NS TS RB EXE. That is the key one that is the one it's actually going to allow us to create a service a -- around. You wrap your head around this for a second. The command I'm gonna show you is not the service that we actually want to create its launch or service there's two components to installing -- service there's instance her. In her. And there's also servant. SR VAN YE XE. These two components pull out create our own custom service however the command and show you right now he's not disturb that actually create. So the two components obviously being like -- for instance her eyes Willis service. And what I've gone ahead and done for making it easier to understand is we've gone ahead and copied serve any. Two weeks -- RC drive. I'm basically the command is as Klaus. I NS TS RV dot EXE. Or without the name of your Customs Service. And then wherever the serve any SR VA and -- program is -- on the machine it just happens -- happens to be an -- drive. Once we go ahead and run that. The service was successfully added and that's a good sign. Now you can't just go to the service has control panel and start your service because we haven't actually defined it yet fossil we need to do we need open up reg edit. Registry editor for windows. If you're not familiar with it. Probably want to be careful because you can serious abort system. Win you've actually run the taller. And creative your own service. What you will see in. The tree. A legal machine. System current control set services were actually going to find. Customer service which is what we just created the command line. Now we can actually set up our application. Inside this registry but first we need go ahead and add -- Entry to this so we're gonna go and do is click new and it's gonna be K we're gonna type in. Parameters. I actually get that spelled correctly. And still check machine correct it parameters. And we're going to create a new string. Being application now applications -- as was actually going to launch our service. And down here in new string value. And okay simplest. Go ahead and edit the application and we can type anything we want. -- Now what we go into the services and MC. What we should see -- as we should see our custom application. Our Customs Service so -- typing custom well that's not a Customs Service right here now we go to the properties of this. You'll see that the path to the executable is SRV Andy dot EXE. That's good. That's as I mentioned in the beginning the launcher application that is going to actually launch or custom application. Like a -- your head around the fact were not actually launching our program from. Server is command. And -- actually launching the launcher service which will then launch our program. Confusing now don't worry it's. So when now that we've actually created Customs Service let's show you how to manage that service via the web. The basic reason that we went ahead and we created. -- we needed to find a solution. So that our community members can manage our games servers that's where this whole process came about. That's where the entire need for Customs Service management via the web and services was created. If you go into. For example are CSS server here and parameters. You can see that we've got the applications strain. On camera numbers -- better power could somebody please throw me at brick. Max players 32 -- rates on so forth we now have the ability to sign users so that they can create their own customs services are excuse me. So that they can administer our insurers forest community project from by the community we also had FTP ability for them. But getting back to the services they can start and stop these service. For the game server at any time. And that's cool that we actually used to do that is penalty. Now some of you may know. Fire. Fighter game and being the service control software -- create automate. Whole kinda stuff with services we don't need that we don't need service automation we don't -- service monitoring if somebody detects the servers down. They had a valid login but. Wired and has created a front end for their application which they released -- open source penalty. Panel Damon is a really nice piece of software that -- is extension to act yes or. Com and allows you to view -- list of the current running or stop services on the box that counting all now remember. I guess or -- are prerequisites. For installing counting it. So if you're comfortable with having. Web service on here box for whatever reasons. -- On personally we don't have a problem with it because I guess the Apache the pretty -- down nowadays -- box updated. But. Here the users can actually hacked vice SS they can see if it's currently running -- it's not running in if they need to you. It connects the issue restarts for the applications. Now I'm not gonna get into installing a basic application you guys are obviously smart. The props are very easy selects port number select the virtual running. You know web application directory. -- just happens to be handled -- but you can mean anything one terror security securities -- Well bill files they'll FTP server is currently running start mode local. -- system auto you know all of this info is available. -- services and Nazi war via the website we can stop all the services we can star all the services and we can also limit. And -- in street guys who we actually have set up. And as administrators on our. Installation. These are your community. Game server Edmonds. This in those all -- Wiki darting notice but. So here. You've got people who have access to only specific services so when they log in panel. These are the only services -- they see. And these are the only service that role now is great for granular granular. Security commission's obviously we don't want. Complete access machines running on it not that you guys gonna do anything to it bought. It allows us to make sure that we have complete control over who has control of what. We normally have control over yet that makes sense. So panel Damon and serve any answer. All the links for the information will be in the show notes yeah asking go to Hak5 dot org or my website met last dot dot com. And now I think Shannon. He's going to. Rapper brings with some trivia and --"

" I this week's trivia it is. What vintage supercomputer was named after stream a raise in its speed and floating point operations per second. If you're the first one in this right and your choice of form whether it's packed -- or this entry we'll send you not only stickers. But also a parent opposes CD. And good at is our sponsor. -- reliable secure web hosting without a long term contract go -- hosting plans are bigger and better than ever with 99% up time. 3247. Support and no annual commitment plus you can register a dot CA don't mean day. As a Hak5 viewer you can get at 10% -- with AK one. And now we're gonna bring it over to christened with packets and."

" Are here we are with the third installment of the packet sniffing extravaganza -- will once again Chris -- Showing us how to actually get her hands dirty we understand high level stuff. How are packed together the lowest layers and it. Let's take a look at some packets an actual traffic."

" We'll be on the building blocks it was -- so we're gonna focus mainly on the wire shark. Program in this in this segment the businesses what we. -- use wires we're gonna go to some of the arrow functions not all of them but enough to go and get him you know aluminum or dangerous. -- without borders what this basically does it and we've kind of heard before leading really -- news exactly doing him. It will capture everything off of a given network network interface. And depending on what options and -- news so did ID call it just -- fire house it. Get our requests he did you know who has a -- interest who has this Mac address who you just get everything. GDP no matter what it is and."

" And again this is great for either debugging is a network administrator or even if -- man in the middle you've got somebody plowing through peace effort that you have access to it -- just watching everything in between exactly we -- that we don't want just want to see everything there's there's stuff that were interested and so you've come into it. What I'd like others what."

" Higher traffic yes we zero in this example you know we have a -- example so have an RC client up. Right here who's going to minimize it really quick camera and go back. -- spaces here. So this is just. This this -- Microsoft. Is this going to start. Now anything immediately you chronicle web browser -- yet if I did Hak5 industry fresh. And yet. Thousands of again there's no one big. -- don't see how small that scroll bar thing is right now its its -- 10096. Packets. Justin on its axis of the -- about it. Great so now we're going to who's gonna stop that one and restore. The Soviet analyst. And piracy here and reconnect. It's actually that there Eisner's. So now we're connected I'm gonna actually guys have a dummy element that's now hit that sit at -- summit message an excerpt. -- And that's thats me let's block. -- mind -- it's one of Africa and and then we're yeah we can do that we can message mixer. -- Release there right. Apparently it's okay. -- now go back here we see you really excited -- bargain. Hit the a lot of traffic and now we want to actually want to like -- this with SS DP it is a whole -- just. They tried strolled around and read it justice so much -- the ads is more than desires he likes expectations though. So we need to filter and this is an ominous stop its Morrissey it's actually. Work with 364 packets. I don't literally go through 364. -- and I'm looking for so what we devises. There's us. Of the musical character filters and also just real time to display display filters -- And so we differences. They capture filter will filtering out before before displays that don't -- Takes we already have so you -- if you. -- so we -- gonna do artsy request. That's the actual screens just -- industries. We're gonna -- contains. Mixer. So this is gonna tell us just everything out at the request is everything that Klein said everything as an -- announced so we can do both the server okay great so I -- for -- party yeah new -- partisan password Yahoo's response or we can responses or even his city public conversation that -- happening with the two people -- response from that person exactly okay so when I hit. And here we're down to treat packets. So all. You can pick and of course piracy is a small that we need to worry about and like path in to use size not to fragment. Yet so what the first packet. So our first -- is actually identified packet there's a password so it's through that's an ambulance. On this. Every gallery there -- cool little invented. And as. It. It's from a password don't use -- actually tried. So so you don't. If you didn't know before. He's not using encrypted you know plain text is just quit. Also remember that when you actually people who you have late user names on servers don't use passwords used -- important things. -- your banking password you know custom create a password that strong but that's you know its its self exam area okay great so we were able to filter just the next serves up. With the highlights the and and and okay so we can going here and right click on this one for example and we color this as well. So we can to stew and you caller all right this code. Creating -- made so now it's different. And you can do this -- rules. Yeah and you can actually go here I'll I'll open season you can look at. But this is where you can go through. And I have this because as we've. -- down that means cancel out of this and you -- see page created. Here's wonder created on your -- request contains Acer that's an ugly but when I think that it is like -- and asking."

" Everything and are -- are just looking to mixer passwords you wanted to sit back watch the whole train and and the lady in red dress comes by -- totally identify herself back in -- blue and red kind of ugly but at least get through to your attention. So. I -- color -- does it filters what are the concept can do with."

" We what do you statistics. And error. -- you agency years you can use statistics from just about any sort of packet. -- I mean it's just. Multi streams different things like -- VO I. VO I. Com you can look at that thumb one of the nice little things that I like to do is pull summary here maximize that. This just gives you a general overview of what happened during your conversation so. We captured a 164 packets. -- like three it just it tells you kind of how long it'll just you know it's a really nice little quick summary of what happened on we get out of that. We can pull this up again and I like to also -- conversations. That's a nice one that I like to."

" So if you're just watching a lot of people are multi chat and instant messengers going and it got -- Rezko and company get past that session. Some of the lots of different types of protocols going time. And we don't even know what we're looking because when you look at the fire is the -- to pull this like well here's what they're doing an iPod and."

" It has to concede there's a fibre channel I mean there's everything is you've got I PV six down here you mean yeah I PX you've got a token ring and so any kind of you know its its filters in South Korea so it's really easy it's just nice charts."

" Again yeah beautiful school. Kind of a lot of information will ruin do you down signal noise and it sees itself."

" Exactly so there's there's a lot more powerful things you can do I mean there's even a firewall -- here where you can actually. Generate -- Cisco violence rule based on."

" If that's that you of course right all of this and you find other resources coming up people. And new rules that hero -- expert and make your own filters and and they just -- addresses. Are right Chris excellent stuff as always. And it. Kick it over and it's dying it's week's party."

" I know Halloween is coming up and a couple of days and I don't know about you guys I'm super stoked coming from the spam -- come from. -- we have a -- paper by digit. An awesome I wanted to tell you guys about our Lan party coming up this Saturday November 1. You -- game died at five hour from the comfort of your own home you don't have to be in Virginia guys you know it's okay. Join us up there played a game -- Austin news. Which means probably can count if you don't really feel like playing in the game go to Hak5 dollar can check -- on the site can't. But for now we're gonna toss it over to the guys talking."

" That's right -- sponsoring the Hak5 Lan party and were excited to be working with them it turns out there in the back I've been watching since. Into this one X three it and edit and also to listen and I've been checking software a lot of fun to use it's like a desktop application but it's totally your browser. Blurs line their little bit between web and desktop."

" Yes square space meaning if yes -- looking to create any kind website or blog or list or anything that's sort square space you need check out. Not only do they have great publishing tools. In my opinion their tools and analytics. Rival. Google or you know you're web trends or anything like that."

" If you use something in the path that like online publishing tool like I don't know Google pages for example. You're getting the wrong idea of what publishing systems can really be like on the web. And he speak universal that that the people over -- face the developers who obviously we've talked to. If if you guys are you know trying to square space and you find that there's something that you don't like where you think should be added. Send us an email so that we can talk to them because they are super motivated and adding anything and everything they can possibly add. I know Kevin and Sarah from Revision 3 people -- requests were implemented in less than a week. Four there -- personal website."

" When he's trying to say is that's where space is basically at least four times cooler than last -- And CD's check out. In fact one of her very own illegal has even I checked -- towards -- and put together page about the Hak5. -- Lan party that's right we're gonna. On Halloween Lian contest then and that is only need to do is on Halloween once you've done for treating or maybe tool that up. Head over to log into that or UT's that -- that organ and an undetermined 99 in the old classics. We're gonna -- be playing countered to CSR five dot org and the battle have to I'm sorry team fortress team fortress -- dot time dot org wouldn't be having so much I'm I'm I'm probably a little bit. On the fences to win the game should plan on going to be in the UT server."

" The and I'm probably going to be an -- drawing the battlefield two server. Through my game but. In addition if you guys have a suggestion or Lan party please this up feedback I've dot org or forums. Or you can go to square space dot com and sign up for free trial and we want you guys Cory and you have five Lan party website. -- that square space dot com sign up for your free trial in addition you'll see the power and the you know capability that square space really offers a feel for you know if you. Use it. Like there's that word press is great but and somebody insure that your site is up percent of the time is our better."

" hey Don and plug it had no idea about when efforts apprentices like it was and it just watched that you on the home page and like. And instantly within a few seconds totally -- it. And of course Hak5 Halloween expert based on three confines -- put up all the details about our then it's Halloween and we hope you guys will join us. So anyway at this point we're gonna go ahead and talk about clustering so that it. Magically and -- snobs about all the fun so you can do it."

" And sound and has all hardware all. He's taken over the -- All the computers Apple -- Real he had real mom and the when he's he's tree hill and you. In particular. It's when you take a look at the hardware and use it -- spread the load -- instructions tasks so lots of hands and work. -- Talking about -- you. -- talking about multiple computers. Well in this instance -- department cluster computing where we use lots of individual computers each with -- operating system at all. Can birds and work -- time. It would work on things simultaneously in parallel we can do it faster. And it. My computer's politics. That we've done here is working me exactly lots little worker -- I need the of these is here and and -- system. And we. Altogether and use all the resources. Hopefully it instantly with a closer. -- excellent -- some other types of arrow keys and there are. On. Well there's massively parallel processing. Which is what you would see and things like. Earth simulator supercomputer. -- difference here is that all the components kind of come together and single machine rather than an author with L actually have their resource gotten. -- Yeah this is something that you that's a companion -- and of course accurate computing. Well are you familiar with -- now. That grid computing. Team Hak5 -- and he's folding home team and you can. -- processing power when your computer's idle screen saver. And starts using it to Apple proteins and -- cancer something like that and the difference there is that it's very loosely organized but only your system resources only join the grid. Win and they're available you know when you're not playing tenor and -- and back. And geographically dispersed so that's the difference between green computing there. Where -- it would be currently in our house -- No what I want to do is -- want to build a Beowulf cluster. It is actually named. -- ethical and epic -- There's actually the term came out nineteen and apps built. This has nothing -- call the Austin but then. Kind of became a general term. Senator with us I mean like imagine a Beowulf cluster that plans are now. Or whatever. But it's become -- generic term for. Yes and she Margaret and author. That's. -- in some examples. It."

" And you want to see an example -- ambulance some of the the systems that that you. So would have got here booted up is an instance. Cluster not X. Now clustered topics in open march 6 its system. And that support all I had. -- my six is a management system for providing -- side which is single system image and and it also allows for simple process migration so. For -- single system image. I'm all of this hardware this this -- here that keyboard and yet here's. All have to run this team at the same image here in this case it's cost optics. Could be a lot there's lots -- Linux distributions that do this. In this case through to season lets not X. And that's -- aside that's the single system image and I opened my six provides but that and the process migration. And that's really weird parallel computing kind of comes and by. Is that we've gotten we want to take something it split up into many processes as possible. So we can distribute the load alternate process you can process Mac and that process and process Paul and and all four of us."

" It break up Lego bricks and build a time capsule ninth Portland on faster. Oh hold hopefully four times faster than would the if we're all individually right. Yeah. Of course. That it's not always exactly four times and you'd think -- so freaking example like patchwork. If I can crack city paid 55 character password. We'll just say when isn't -- and in like four minutes with one computer. You think that idea what to do it into two minutes for cheap computers. One answer. Electric -- computers yet every time double we actually fastened to. Not exactly right there's there's a single -- law which talks about the way that the program is designed and the efficiency. That. That's there and it really talks about the bottlenecks of the design program. And it's a way for you kind of estimated age. What. What kind of of efficiencies you should expect for different programs when you actually do a multi processor. Or a parallel."

" scenario so are you saying that since we have different kinds of computers different kinds of CPUs. We won't get as much efficiency as we wait if we had three right now is the exact same computers."

" There's a lot more involved. With it than just see you while these are all three different systems running it different. Yeah different architectures because -- different companies. The ring at different speeds you've -- to denounce him. Not know the OS is exactly that's SSI again. He's insisting on it or running -- not picks up faster topics right now so that's. -- operating systems all things but they're there hardware differs vastly and even. You know that are just kind of idea and the -- network in this instance the network is kind of the bottleneck. Because it's 100 megabit network. Rather than the Gigabit and that's just the limitation of war which accounts that get them in bigger and plot it out let. Yes so. So that's that's different there. Of course it would run a lot more efficiently all the same hardware. But of that to factor into its -- actor instantly that it's the whatever is that we're doing multiple processes is is written so that's and the law. I guess that I -- an example here in Austin optics and would have loaded up here."

" lots of New York mafia is a open source. Alternative to mark six like to spokesman inconsistent yes -- process migration. And what do -- load up. And you can see right here we've got. Three different machines and we've got into it there's Iraqis we can see the room -- allude. And see their memory usage here is it -- some units in this instance of the three computers because one of them. -- So. That would be neat yeah. -- It's a proposed to cut the cord I don't know seriously. So I'm just show an example and there isn't any different reasons why you want to do -- be it all home rendering out. -- up our own view yeah rendering -- case about that. You know. Though. It's become a little. On the benchmark and it managers here as an example is -- Has yet. So -- that he would have got here. Path and dvd and you can see I've got a couple of patches here and these are just and he on -- Yeah from windows is going I just went -- which police one machines within DS passwords. Here's sensitive or anything. But. -- tendency here got my user account Aardwolf. Here and I can't go ahead run -- against say Katherine crack. And I'm just. You reports -- and -- and and it creek and he did anything like what aspirin factories and using this one that called yes. Totally that's opening here it's called to sell. -- art and that'd. And you could use to like them rapper but this is it makes it really easy to split up jobs and multiple processes. And then through process migration with the optics. That are all processors and split up and you'll see here runs going to go ahead run as you can -- you Hopkins and in the -- Customers -- Okay so. And run this command here it's -- So prologue test file North Korea here where do you attack and four that's how many process is ongoing on. And this of course have to use the file got from yeah. Song and split the four processes because again down here actually have four CPUs to use. Because they've got three computers multiple -- and run that. And I -- you can see also outlook. That that this machines and 91%. Because it's doing all of that at once and analysts and we -- And that's where the process migration I'm up in and exactly to -- hey guys we audit crap did you hear him just kind of pitches and hold it hopefully -- would all get 200%. On much past work force -- got -- here. But that's what I want to build something where everything's the same hardware and on another network unity color and it is so accurate it's already done. And you can see. -- user Aardwolf -- be the real simple and he'll eat well and so -- think -- I mean that's not really fast and -- is prepared passed between us here it was yeah it's got a dollar -- But they're that the one."

" On some of the collect on open -- prisoners and that we use that. And that's that's -- in case. You are important there's opened library. Pipeline the use -- basically speak all of the other computers and network and here they're cute they're an image. This work. And it. It's it's seeing. API it's not standard if you well. It's become a standard in the sense that it's active standard but only needed -- and accurately standards body. Specifications. Thoughts. Just like you that. Microsoft cluster server.

There's gonna it will this cool that you could use this to generate and tables uses to support. Did you rendering is one thing I'll do it. What's the difference between. What with rainbow tables and we've talked about in the past second season. The real quick and basic ideas time memory trade off.

Audio out of sync very much?

Great episode.

Oddly, I was just thinking about building a cluster. I don't know why, I just want.

Weird.

Yes, we do acknowledge that there are some audio issues with this release, and we'll be working our hardest to get these ironed out for the next shoot, however we're still looking to get the final piece of our HD setup (mac pro), and if you can help out please visit http://www.hak5.org/stickers and donate.

Thanks for watching!

You can't use a cluster for f@h. A gigabit network can't handle the bandwidth between the nodes. Maybe with a Low-Latency Optical Network.

I would buy a sticker, but the thing is - I live in Sweden.

The shipping alone would cost around $10-15.

Just post your paypal-address and I will send you a couple of dollars next week :)

folding@home uses a distributed model. It completely embraces the highest of latency networks. Honestly, you wouldn't need a cluster for it at all, you'll only introduce massive bottlenecks.
Assuming you guys can't afford a real interconnect(myrinet, infiniband, federation), you're going to want to be quite mindful of local memory bandwidth, to make up for a poor interconnect. Tasks like video encoding are great for these setups, you can feed mencoder binaries on each node a seperate offset of the input and just chug away. No massive collective calls, latency won't bite you as most of the task is localized to the node. You'll still have (inefficient) serial components of the workflow (joining chunks, muxing sound), but that's the nature of non-MPP workflows.

Software wise, stick with proven packages. If you're doing mpi, get mpich2, if you're doing smp, stick to openmosix. Cluster distributions are a dime a dozen, if you've got disk to spare in each node, just get Rocks and setup cfengine. Get yourself a small NFS server with a halfway decent raid (even software based is fine) setup. You should be getting better than single platter speed here, a 4 disk raid5 on even a sempron will get you 75+MB/s, respectable for a 5 node cluster. If you're feeling wild, get two gigabit switches -- dedicate one to NFS or whatever storage technology you're using and the other to the rest of the job traffic (mpi, etc). If you're *really* going to build a cluster, get yourself Maui/Torque and have real job scheduling (but really, you're just going to end up punching yourself in the face rather than deal with the annoyance of batch queues).

Above all, balance your hardware. Focus on getting the most memory bandwidth (ever wonder why opterons are still wildly popular in the HPC sector? on-die memory controllers and hypertransport), don't overload one node and underload another, it's only going to lead to idle cycles on the beefier machine. Get good NICs, make sure they do real checksum offloading (any processing you can take away from the proc, the better).

Remember, there are no shortage of resources out there regarding linux on commodity clusters. Just keep lookin around.

I mean, you can't use a cluster to run the f@h smp client(cluster within cluster).

oh, absolutely, nowhere near all SMP code really benefits at all from an openmosix setup.
