" This episode -- private brought you by -- here godaddy.com and Netflix dot com and Darren Kitchen."
" It's like available for cooking."
" Everybody welcome this week's episode of Hak5 I met last knocked. And I and Shannon wants the as a -- haven't seen act five before or show focused on everything from. This is administration to gaming to -- Anything we could possibly -- of the -- relatives who we like call technolust."
" And this week we have a whole bunch of new stuff for you I'm gonna be talking about synergy which is that have left him -- that makes it to."
" I've got boxing which is a friend for the X and -- system. It's runs on Linux and Mac aggregated -- that awesome you can harness these social power all of the media."
" Well what about eucharist."
" Let me ask starting at three part series on -- thing going over sort of the fundamentals tools and finally wrapping up this techniques and they're already talking about today taking a look at whatever community member creations and that is important -- for windows. So anyway let's go ahead and kick it off Matt let's see what's gone on --"
" CNET are probably really aware of that Xbox immediate its future -- out upgrades and you can music on windows and Mac clinic."
" And he's gonna show us the new front and called foxy for the Xbox media that's rights and boxy is currently in and now the stage. You can go ahead and download yet we are working with the boxing team trying to invite codes -- number vote. Viewers colossal watch the forms that it felt behind us here you can actually see we've actually got something playing now boxy."
" Box is social media or social networking with media. Soul. Your big social media and so what we can do with -- is we can actually apply. The social networking model to our own media that we can share media like movies and music like that exactly -- which I'm sure so right now we're we're playing a song be Alaska that. Not our song. It's a song that one of our friends and I actually -- it's do you wanna buy the cooks. So what we can do is we can go ahead and back out escape. Here you see the main page of -- What -- is like this it is a front end for the eighties. Up here we have our friends' activities. So everything. That they are watching listening to or recommending. Is actually listed in this first page right here. So. This isn't music -- recent -- that that have -- who is one of our most. Frequent. People on boxy which he's watch what he's this. On actually watch the movie that is watching you can't watch what you most movie -- You can actually watch trailers for the movies and you I you can actually you know watch the trailer and see you liking it and download it. Other than that what you can also do we shouldn't go into a movie. And we can go into. This. Movies that Abner watched and it's apparently -- Released in 2006 huge all kind of music information about the movie. And we can go and we can rate and recommend. This to our other friends if we watched it so if we read it we say we love it great ratings sent. Now that's going to apply to all future. Recommendations that box it'll actually. Send us -- you like this well. You might like this. The other great thing about biopsy is because its Internet connected -- Internet focus. What we can do is we can actually watch and listen to Internet and he. So where it's kinda like streaming radio. Streaming radio and streaming video just like Revision 3 is actually revision three's preset. Inside of boxy that's actually go ahead and take a look at that now. Video Internet videos you can also do just like Xbox media center you can do you or. Medium but we're gonna go out and focus on the Internet -- a provision. That can do as we can go ahead we go to Revision 3. And say we're going to creative oh jeez I don't know let's go ahead and watched the first. The latest episode they are buddies Kevin marks. So here there at the brewery and we're actually gonna go ahead and play. The video that is on the Revision 3 street. It's gonna go and catch it and offer and that. No it does. So here we've got the latest episode Diggnation -- behind us on and -- is like I said before its alpha. It's also meaty social networking with your media. It's great for an end and read. You know recommend. Items for. You and your friends so quick -- to get. People go to boxy BO XEP that he easily should be right. Here com the -- I mentioned before alpha. Can't download yet which can sign up for the L I guess that we're gonna trying -- an invite codes for the very selective. You people. Another reason three forums or act -- forms and look for."
" Great thanks Matt no definitely gonna check that out once it's out of alpha. And I think."
" But first time this week's trivia and this week's trivia question is an optimal PP oh he frame how many bytes to -- fighters had. To the total brain size and what -- finds that. And of course you can submit your answer to the -- five orbiters in three forms to start a thread called. Apps support six trivia be the first answer 1 -- you get the ones who are five goodies. Also I didn't remind you that -- trivia is sponsored by. Backs the number one German beer exports to -- by choice and they invite you to check out the back universe of choice that's right. Got a relationship issue -- dilemma has an it professional advice when you've got insightful perspective of local backs drinkers at XP -- dot com. He'll find the universe of choice a lot polling engine that lets you submit an issue. Or life to limit the community back drinkers for real time voting log onto Beck's beer dot com for full details annually on more enlightened person. Sort of take a quick break and we get back it's Chris grilling -- So as we may know our Internet communication is made up packets which are really just a puzzle pieces of our network traffic. And here to explain to us how that all works and packet sniffing Chris grilling securabit --"
" I'm right at the hottest area comment about her out of it for the podcast as a soccer it's yeah. Yes so yeah we we just talk about it and you know leading that is so cool well this is on this if you talk about that a fundamental overview of what packets that thing is and why would we wanted to. Right packet sniffing is essentially eavesdropping. And it's obvious see what's going on network receiving packets that are coming across and once you. What's going on -- information meters below very -- left now why would we wanted to view the white hat and black hat -- music video like debugging testing. Do a tree protection monitoring want to actually fragment from a defense standpoint you know. What's going. Way he knows what's going on and from the galactic greatest point. You're you're you're more concerned breaking things man in the middle type attacks you know -- selective for example on demand and -- and -- between you and -- way I can now watch cross wired its elected to interest in York and loans and passenger traffic -- York HTTP traffic information gathering. I would want a decent packets I think -- that they can actually see. You know what's going through the wire act and then on the -- obviously some software developer network administrator trying to tweak my network see what's going on -- performance. -- Actually born here at a at a okay so what are we gonna need to know what these terms in the east schools needs now are -- so when you know about what's -- you know -- model has -- seven -- you know -- explain -- better -- You know how packet how information travels the network okay so this is everything in between. The copper in the ground and your monitor so let's start with high level break down look at our monitor we do here is spoke at. Heck I've setup -- right services layer so basically whenever kind of layers five sixes. This is easier to monitor is what actions meant for the packet then built an expert here. So this is just what you normally users will use the price it's the applications few sessions. And so that's not as interesting for the packet sniffing so what about the one -- okay form below -- in Portland will -- custom tools there. Form below basically is your airport has to do with the transport. You know what what protocol used -- to be unique among is going to -- going to be you know TV. Oriented. I'll layer three's where your actual packet resides that's network layer that's where you get into you know. How packets that other sorts of you know address destination addresses you know a lot of information to -- okay what's going here actual structure of these little bits that are gonna -- reassemble them together and hopefully the -- we we think it and hopefully -- And then layer two and one and he sent them physically Mac addresses and your lawyer wireless it's -- and then in the physical layer and we're talking about like microwaves whether it's. Whether it's. Ethernet cables -- its undersea cables satellite okay on stuff that the Internet only does -- realize that you know in conceptual term link in the snow crash term isn't there so. What do you -- slogan he's here some -- the user wire shark he's -- there's a few other ones they eat into we're just gonna talk butler fair right now. On you sleep habits and now these tools allow us to do -- interest in with our network card here that is to put it in. Monitor -- promiscuous human explained in what these terms mean definitely with monitor that's it's kind of like just looking at the traffic anybody can you there mister -- this monitor what's happening between your machine network. Com promiscuous and is -- that's where you are able to actually modify traffic you know with the with the protocol analyzer and certain things you're doing random meant to attack can change your secrets number. That's when you can actually Easter you know."
" Test so monitor -- is really just listening. Listen and then they that this is now a great example -- air and air on exam where I'm actually listening for your traffic -- wireless and and I decide that instead of getting to Google banner image. We'd rather give you -- picture that. Yeah that's okay. Cool so -- all of the tasks you with like especially with promiscuous modifying these packets. You have to have a pack here and get a high level of review -- All entails and packet. So the next time we look at this. We can actually use this war properly and and understand it a lot aren't we mentioned that this is going to be part of three possibly four part series. This one ago yes so look at the fundamentals and -- artists to dissect the -- a lot more and and they're using the tool and and we can use an advanced techniques and filtering so right here I have this is just."
" Of Leo attacked five and just captured the EP you know traffic. And out his pleasure I mean there's really quick. Answer to disclose the are you conceded we're doing again request. Four you know -- image has got a -- I -- that if the bandwidth link to others in -- image hosting. Yeah okay and in you know we're just grabbing it pagan and use those things is about one of the you know hundreds of packets that are involved in actually getting back on that website what's the problem there topple over here is pretty much here here's later won the frame. Were open that up and assisted you know. How how big the frame like there is analyst at this this is information that we're not too concerned with right now but Alexis no link at what time it was sent what time to -- came in and you know how what -- frame is where so framing is really important for the reassemble process framing is very important pregnancy with numbers because typically I don't just say. Give me everything Hak5 and it just gives me giant businesses thing at the giant Hackett hack you know awesome electric you have to let it. Limitations and how big packets can and can be and how much data there is that we split into multiple songs not for the training gets involved. Okay that was that are. The second one as does -- your Mac addresses not too interesting but this tells you. This is basically saying they from the switch to me this which says -- network interfaces. Great. So here we have layer three -- This is where you say are source IP address I PV four underlying this is where things you pre existing. Where you can actually use the fragmentation. Things like that well we're replicating it in more okay. I'm that you're transmission control protocol this is your act -- piece of the first one the -- we just looked -- IP here's the PCP. CP IP. Leaders concede flag users that are pushing. And different things we're definitely in great."
" More than need to know that so get into the next time the flag mean and then finally the actual payload of all this legal all of that -- stuff. Just to let you know. What I'm telling you -- be put into anything got to Hollywood I'm telling you can tell you what order it's gonna come and otherwise in my committee be corrupted that's what happens when you download files than there corrupted. -- packets came out of order. So finally we have the payload and we actually see. That it's sending us the leaders -- HTTP yet and we can tell user agent is Mozilla and -- gravity thank you for hosting the images pack five. Awesome so what can we got a good -- understanding of what packets that his. Why we would do it. And -- and what you know the anatomy of a packet really is so -- next -- next week can breaking and going to outstrip I moved in from Virginia -- to return. But don't you guys just editing you're gonna come back here there was great -- and a packet. Dissecting a packet and then checking out some -- techniques of things that. Chris thank you as always awesome segment and we're gonna take a quick break. And come back. Some fun stuff going on -- Crime and synergy. Now it's time the Lan party. He has is that a lot of the ones you like it's an open source games that that's exactly what we're doing now on October 18 we're going to be playing war so. It's basically like well -- in an open source game based on the quake three engine. Kind of similar to quake three a a lot of fun and I hope you guys join us. October 18 at game pack five dot org and of course the Lan parties sponsored by Netflix would want to thank them. When Netflix you can rent over 90000 titles online with free shipping both ways -- home. They have over forty shipping centers so almost all delivers happen in just one business day. Netflix and start it point 99. And as a number pack five -- get a no risk two week free trial membership ticket out at www. Netflix dot com slash Hak5 and remember the WWW. That's very important. Okay so before I head over to Shannon and not to check out -- not out until you guys about creation from our aryan community member on the he's developed a tool called. -- for windows that's exactly that and if you're used to the unix environment you know -- Fon is a great way for scheduling tasks. And this will allow you to do just that in now windows without have to use the kind of archaic and not to feature for windows act -- or task scheduler. So you can get it Tom bell and dot org and I want to see the really nifty. And Kron tab that here. Based on XML so you can see it's really easy to set up an XML file has schedule. Minutes hours -- of the month. Lots of different ways to schedule and it's real simple -- matter of setting. The our arguments here and our programs that we can see look at the rags. Real simple. Easy to use read documentation stalls is when news service and I highly recommend it and it you've got more grace -- your software developer and a number of our our community would love to hear from you guys have this up on the forms. Now and go ahead of him that in plain."
" Some -- Clinton. Yeah is actually this -- platoon mod called synergy odd and it's. It basically lets you play any multiplayer -- lets you either have let you. Episode one episode two -- through those. With multiplayer. You can play up to 32 characters in the same server or on a local land whenever you want. And so I think it would be pretty cool to have three. 32 Gary freemen's."
" Gordon Freeman and if you would Gary you know his close cousin you don't -- Yeah exactly Gary's mod Gary Freeman geared Gordon. Anyway so yeah we. What do we need to actually go ahead and play synergy."
" With each other there's only three things that you need and I mentioned that this can only play on either windows or Atlantic. Sorry guys are Mac users you know you're. Sorry. He needs steam first of all nothing you source at the cave days and you need to have half -- to -- actually by the then you can buy it on mine -- You often need out. To have the same version as your friend airplane it's not with you. So you can just -- synergy mod dot net and download the new whispers I definitely suggest -- the beta right now so. Most of my friends -- probably can play -- so uniting things show up in their access. I I'll try to go to their server and they're not giving anesthesia I'm gonna be like where are you guys. I won't even be on that obviously an air base here yet he has a crazed maniac yes you can see I'm actually. Playing Catholic too right now I'm in the middle the game. Playing with. Darren every year hack ID and and -- so my so we're actually in a -- half -- that most people -- experience. Young single player. So imagine. Looking around here with 32 different people playing the same game as you and going through half life have let -- in what maybe a couple of hours."
" Yeah we're gonna happen and it is now an operator that accounts and how fast we can actually go and complete. You know each and half life it. Yes and follow us on twitter Hak5. Or you can follows on the forums where every post and let you guys know what we've got you know exciting things coming up with community and things of that nature works in -- planes and I'm also we want you guys that you always check out forums.

Yeah okay and in you know we're just grabbing it pagan and use those things is about one of the you know hundreds of packets that are involved in actually getting back on that website what's the problem there topple over here is pretty much here here's later won the frame. Were open that up and assisted you know. How how big the frame like there is analyst at this this is information that we're not too concerned with right now but Alexis no link at what time it was sent what time to -- came in and you know how what -- frame is where so framing is really important for the reassemble process framing is very important pregnancy with numbers because typically I don't just say. Give me everything Hak5 and it just gives me giant businesses thing at the giant Hackett hack you know awesome electric you have to let it. Limitations and how big packets can and can be and how much data there is that we split into multiple songs not for the training gets involved. Okay that was that are. The second one as does -- your Mac addresses not too interesting but this tells you. This is basically saying they from the switch to me this which says -- network interfaces. Great. So here we have layer three -- This is where you say are source IP address I PV four underlying this is where things you pre existing. Where you can actually use the fragmentation. Things like that well we're replicating it in more okay. I'm that you're transmission control protocol this is your act -- piece of the first one the -- we just looked -- IP here's the PCP. CP IP. Leaders concede flag users that are pushing. And different things we're definitely in great."
" More than need to know that so get into the next time the flag mean and then finally the actual payload of all this legal all of that -- stuff. Just to let you know. What I'm telling you -- be put into anything got to Hollywood I'm telling you can tell you what order it's gonna come and otherwise in my committee be corrupted that's what happens when you download files than there corrupted. -- packets came out of order. So finally we have the payload and we actually see. That it's sending us the leaders -- HTTP yet and we can tell user agent is Mozilla and -- gravity thank you for hosting the images pack five. Awesome so what can we got a good -- understanding of what packets that his. Why we would do it. And -- and what you know the anatomy of a packet really is so -- next -- next week can breaking and going to outstrip I moved in from Virginia -- to return. But don't you guys just editing you're gonna come back here there was great -- and a packet. Dissecting a packet and then checking out some -- techniques of things that. Chris thank you as always awesome segment and we're gonna take a quick break. And come back. Some fun stuff going on -- Crime and synergy. Now it's time the Lan party. He has is that a lot of the ones you like it's an open source games that that's exactly what we're doing now on October 18 we're going to be playing war so. It's basically like well -- in an open source game based on the quake three engine. Kind of similar to quake three a a lot of fun and I hope you guys join us. October 18 at game pack five dot org and of course the Lan parties sponsored by Netflix would want to thank them. When Netflix you can rent over 90000 titles online with free shipping both ways -- home. They have over forty shipping centers so almost all delivers happen in just one business day. Netflix and start it point 99. And as a number pack five -- get a no risk two week free trial membership ticket out at www. Netflix dot com slash Hak5 and remember the WWW. That's very important. Okay so before I head over to Shannon and not to check out -- not out until you guys about creation from our aryan community member on the he's developed a tool called. -- for windows that's exactly that and if you're used to the unix environment you know -- Fon is a great way for scheduling tasks. And this will allow you to do just that in now windows without have to use the kind of archaic and not to feature for windows act -- or task scheduler. So you can get it Tom bell and dot org and I want to see the really nifty. And Kron tab that here. Based on XML so you can see it's really easy to set up an XML file has schedule. Minutes hours -- of the month. Lots of different ways to schedule and it's real simple -- matter of setting. The our arguments here and our programs that we can see look at the rags. Real simple. Easy to use read documentation stalls is when news service and I highly recommend it and it you've got more grace -- your software developer and a number of our our community would love to hear from you guys have this up on the forms. Now and go ahead of him that in plain."
" Some -- Clinton. Yeah is actually this -- platoon mod called synergy odd and it's. It basically lets you play any multiplayer -- lets you either have let you.

I'm just curious, what tools were you using in the show (I'd might have missed that part) for the package sniffing.
I know all about nmap and those common applications but i was wondering if you guys had some really neat application that had some extra stuff that others don't. (besides home made applications what are there out there?).
I tend to use sniffer myself on my windows box since it has almost anything about network administration, security and such.
http://erwan.l.free.fr/ a great guy who i talked to for a while back in the days.
Don't know if he's actively developing it but it has a lot of nice stuff.

This episode contained some interesting topics (as usual, I might say), but I'll agree with Unhap that it seemed really short. At 24 minutes it is only half as long as the 3 first episodes this season. The same goes for the previous episode btw, and I hope you're not planning to make them any shorter. It feels a little meh when you see a new episode being downloaded in Miro and think "whee, I'll watch that at once" only to find that it's so short. They don't have to consistently be 40ish minutes, but it would be nice to at least get 30 each week. I think that would also make the content seem less rushed than it did this episode.
I also found the "let's pretend Darren is actually here at the time of shooting" thing a little awkward. It was pretty obvious that the segments with him were prerecorded, and I think it would have worked out better if you had just started out saying that. It's not like there's any shame in using prerecorded segments in a prerecorded show.
In regards to the OSI model, it can be pretty tricky remembering the order and names of all the layers. The phrase "Please Do Not Throw Sausage Pizza Away" was originally taught to me years ago by my CS teacher, and has worked well as an aid for me to remember.
For the uninitiated: The first letter of each word is the same as the first letter of a layer in the model (and in the correct order). And the phrase is sufficiently silly to be easy to remember (especially if you have a strong distaste for sausage on pizza).
As far as Free/Open Source LAN games go, I highly recommend OpenArena if you haven't checked it out already. It's basically Q3, and you can't argue with that.

When I was in school I had to learn thje osi model also. I have forgotten most of that stuff. I need to go back and refresh my memory so that it is easy as remembering the color coding on a 4 pair cable.
Packet sniffing is fun, You can really learn about what goes on in a network. but you have to be careful some network admins get nervous and will shut off the port you are using on the switch if you are caught doing it. When I was an admin I like to do sniffing when the network was slow. This was before we heavily used managed switches,. Sometimes you had a screaming nic or someone is intentionally flooding the network. Before tcpip became pretty much the the standand. Old networking games would use what was called ipx that was popular with novell networking. It was really easy to catch the gamers doing it on the school network. We just nicely asked them to do it somewhere else. Apple has it's own protocol but they have gone to tcpip also. It was real easy to see if someone had brought their own apple computer to school to use by seeing those kind of packets. Every nic (network interface card has what is called the mac address or a sort of serial number for the nic. Most of the mac addresses were based on the manufacturer of the card. It was easy to tell when someone had their own computer on the network because you could tell by the mac address was not the kind of nics in the computers that we normally used. Besides we had a database of all the cards in computers on campus. Non standard mac addresses were investigated. Usually it was just a teacher who had brought their personal laptop to work. No big deal. If you like to play detective, you will love packet sniffing. I am just a beginner at it though. I can not wait to see the future episodes about packet sniffing.

as for the episode, it seemed really short. you guys couldve gone into a bit more detail on synergy and boxee i thought
