Missing pieces

Everything you should know about technology, but have been missing out

Security podcasts

, ,

I have listened to various podcasts for over an year now. I though I might share some interesting networking and security related episodes. Some of these podcast episodes are easier to understand with bit of network knowledge.

If you need good overview of networking, Run your own server might be one of the good places to start. As shows name suggests, it's from the point of view of running your own server, but there's for example one episode about DNS, that explains some DNS concepts.

This episode of bsdtalk deals mostly with honeynets. Basically it's a service that looks like ordinary server, but is set up to gather information about the intruder.

SCTP is sort of crossover between TCP and UDP, it just does some things better.

This episode at sploitcast deals with ISP level security. Quite advanced stuff, if you're not familiar how Internet works on larger scale.

Security Monkey has podcast too. I just can't remember any particular episode that I should link.

So this time bit shorter post, but on the other hand, goind through the linked content should take some time :smile:

PS: thanks to http://openclipart.org for saving me some time.

Back to the IPTV

, , , ...

I have posted previously about IPTV, or been close enough about that subject. IPTV has some other names too (like vidcast). I'll just use IPTV, vlog doesn't really describe these shows, vidcast is more like it. But even people making those shows are not always certain about the thing. Wikipedia seems to suggest that vidcast is the right term, but some shows describe themselves as IPTV shows.

So by using IPTV I don't mean the corporate version, that means means just sticking to what the proprietary IPTV network can offer you. I mean shows you can download and transcode to any device you want to watch them with. You just need Internet connection. Sometimes transcode is not necessary as shows are already available in few different formats.

Previous posts about this issue were just links to various shows, this time I'm going to get little deeper with some shows that I have watched more than one or two episodes. And it's good to bring this this topic up again, as some (or most) of you haven't read the archives.

Some shows are not for the minors, as some shows contain swearing and alcohol usage. I guess only exceptions to the rule are DL.TV and Crankygeeks, but they're both more or less corporate shows.

Other thing is that security related shows show things that could be used for criminal activities, so don't blame me if you do just that and get caught (not that it's any better if you don't get caught, it's still criminal). The decision is yours alone. On the other hand it's good to know these things so you know how you can prepare yourself if someone tries those tricks on you.

Games

I don't watch shows about games much, but I have watched one episode of Openalpha.tv. I'm not sure yet what my opinion is so see it for youself.

News

Crankygeeks

Crankygeeks is John C. Dvoraks show, so if you really hate him, it's better to pass this show. I can see why though, sometimes it seems that he doesn't have a clue. Luckily Dvorak is not only one talking and there are three guests too, though Sebastian Rupley is more like co-host. And they don't usually agree with Dvorak.

So basically, the show is half hours of discussion about news stories, so format in itself doesn't mean a good show, it's more about the people in it and guests have been good enough so far.

Diggnation

Diggnation is basically rehash on few stories from Digg and some commentary from the two (drunk) hosts, Kevin Rose and Alex Albrecht.

I have not watched Diggnation for a while, but I guess it has its moments. At least recap of Diggnations best moments was not that bad. I'm not sure if I have time to still keep watching, there's so much else to do. But some people like it, so it might work for you.

DL.TV

DL.TV is one of the shows that has bit corporate backing and that means there's advertisement breaks. But I like the hosts, sometimes there's too much gadgets though. But in short DL.TV has news, game and gadget reviews and sometimes other stuff too.

Host are usually Patrick Norton and Robert Heron, unless other one is away. Usually backup host is Roger Chang (normally behind the camera) or Jim Louderback. I don't know if there have been others.

Pure Entertainment

Pure Pwnage

Pure Pwnage is "reality" show (or at least I hope so) about game addict. First episode bit of too much of the reality show part, but second one is much better. Just imagine what happens when game addict tries to pick up girls...

TikiBar

Tikibar TV is show by Jeff Macpherson, he has done some real work in the film industry too, so he's not completely inexperienced.

Almost every episode goes like this: there's some problem, doctor writes a prescription for a drink, problem is solved and there's a party. Doesn't sound like much? Well some episodes are not that good, but they're short enough. Most are quite funny, if you're not impressed, check out some most popular episodes.

Quite impressive for a low budget production, part of the "quality production" look comes from clever use of video effects and good soundtrack choices. If you decide to watch just one episode, try Red Oktober.

The Scene

Scene is the place where the pirated goods come from. First season has all the action on the computer screen, there's small picture showing the actor too. Upside is that The Scene is most realistic computer fiction that I have seen. Second season has shorter episodes and bit more scenes around the computer action. Of course, everything important still happens in computer screen. But this time text is easier to read, because camera zooms to the relevant part of the screen.

I haven't been watching The Scene for a while. First season had it's moments, but mainly watching other people chat can be bit dull, though it worked suprisingly well. Second season has been more tight in many ways, there has just been many problems with RSS feeds and downloads, so I have not been checking for a while. But now there's good change for it, as second season is ready.

Security

The Broken

The Broken is show about all borderline illegal hosted by Kevin Rose and Dan Huard. There was episode that showed how to crack wireless network and how to get free pizza. Also they show how to play backup games with game consoles.

There hasn't been more than four episodes of The Broken, but that means getting up to date with show is fast. All four episodes have been good so far, some cracking and hardware mods. I guess some game console giants won't be happy about this show, though I'm sure that same information is available from elsewhere too.

From the Shadows

I watched only one episode of this show. It wasn't that bad, but I'm not really into game shows. Though that episode was more about what you can with portable game devices. So I was wrong, rest of the episodes are mostly about security, so maybe I'll need to watch more episodes.

Hak.5

Hak.5 is technology show which includes hardware modifications, security stuff like password cra...eh recovery and various jokes. Some jokes are parodies about various shows, so be sure to check out originals first. There's at least one too that works better if you have watched few episodes from first season first.

Show has gotten more professional, but second season lost some of the fun that was in first season. That might be because some of the crew left. But it's still worth watching, there's not too many shows like this as The Broken doesn't have any schedule right now, it's not even sure if there will be another episode. On other Hak.5 comes out more or less regularly.

Tutorials

Systm

Systm is another Kevin Roses and Dan Huards show. It includes tutorials about various topics like MythTV, Asterisk and podcasts. Latest show is about Maker Faire and worth watching if you're interested in inventions, modifying and tinkering. It's not so much about computers as other episodes.

I'm not sure if there's more episodes coming, Kevin Rose has Diggnation and not so regular The Broken too or he could be busy with Digg. Dan Huard has ScopeTech and Revision3.

"TV" Networks

Channel 101

I still have not watched their show, excluding two episodes of Chad Vader. But idea behind the network is interesting. In short, is that shows are shown live and audience decides if they want to see another episode of the show. Most shows don't last long, even very popular Chad Vader was canceled after two episodes. But that means that creators of that show can experiment with new ideas.

Mathclub Productions TV

I have not checked out what they have, but at least there's few drama shows and I have not seen too many of those freely available.

Revision3

Revision3 seems to get out lot of content and shows that I have seen have not been not that bad. Choice of formats should be good enough for most of us and if you want to share your bandwidth, BitTorrent downloads are available too. Though Mysteries of Science was bit of a dissapointment, I thought it was more of a science show than not so funny one minute of nonsense.

Phishing and other online frauds

,

You can always make sure that your passwords travels over the network encrypted, but if you give your password to somebody voluntarily, it doesn't really matter. Opera is developing a phishing filter, but that's not a perfect solution.

So what can you do even without any phising filters? Don't tell your password to anyone, not even to someone claiming to be doing maintenance. Real employees don't need your password, they already have the power to do anything to your account they need to. Other form of phising you can prevent by always typing the address of your banks site by yourself, not by following a link in some e-mail.

Another thing is those Nigerian letters. There's group fighting back them back and they have quite interesting stories. If you get e-mail that offers you large sum of money, it's quite likely your are about to lose some money if you fall for that trap.

Update on Last.fm

,

I practised what I preached and tried to get more out of Last.fm. Recommended music is fine, but sometimes I listen to some artists that bring some artists to the list I don't like that much. It's possible to dismiss them, so it's not that bad.

I subscribed to some music related groups and that seems to be good way to get some interesting recommendations. Amarok group is nice, but that brings very broad range of recommendations. So I added progressive rock and progressive metal group.

Listening to group radios (that are generated from music that people in group listen to) was interesting experience. Bit random music, but more good stuff than bad. Seems like there's much more good stuff if you listen for a while.

But there's even better solution, global tag radio. That means that it plays music that people have tagged with certain tag. I'm not sure where to find more of those yet, I just copied one from another user. There's some in Amarok too, but heavy metal radio wasn't so good. Progressive rock radio works though, there's some metal in the mix, but it doesn't really matter. I have not yet heard so broad range of progressive rock anywhere. Most Internet radios don't have so large selection of music when there's random mix playing (at least when I'm awake, most stations that I have found are in USA).

Seems like I will be listening to much more Last.fm in the future.

PS: I found the tag radios, they were in plain sight all the time.

Protect your privacy, part 3: Anonymous networks

,

There's few ways to further protect your privacy. Anonymous networks are one of the most effective ones. Of course none of these networks guarantee absolute anonymity. Maybe most useful where freedom of speech is really threatened, or surveilance goes too far. Otherwise you can access vast amount of knowledge much faster through public unencrypted network. But if you're bit paranoid...

Imagine you could publish or access anything and nobody could track you down.

Freenet is anonymous network providing distributed storage. Information is stored in pieces in several nodes over the network. Nodes don't know nature of the data they're storing and those pieces are replicated further if there's enough requests. So it's hard to remove popular files from the network, unpopular just vanish over time.

From version 0.7 and newer, Freenet doesn't help you to find nodes you to access the network and you need to find at least three by yourself. Good thing about that is, that you can add friends you can trust as nodes. That is very important in cases where simply using Freenet will cause trouble.

But if you connect only to your friends, how will you access information that's only available from complete stranger? I'm not actually sure if I understand how the routing algorithm works. One paper described how Freenet arranges nodes with similar interests closer to each other, but that paper described algorithm that was abandoned, so I'm not sure how it works now. It should use theory of small world networks as its basis.

I2P doesn't have distributed storage, so server that has the page you want is either up or down. Nature of the network allows using almost any protocol (there's for example builtin BitTorrent client) and it allows almost realtime communication between nodes. To achieve more anonymity you can give more bandwidth for routing traffic from other nodes, so it's harder to know which data is originating from your node.

Most unique feature of Tor is that it can offer outproxy to nodes in the network, so people can access public Internet through Tor as long as there's at least one outproxy running. Tor allows also running server inside the network to hide identity of who is running the server. Tor might be most popular and faster than two previously mentioned, but that means that it can't protect your anonymity so well. But if it's fast and easy to use, it's not a suprise it's the most popular one. There's for example Firefox based package named Torpark, Opera based OperaTor and few LiveCDs that include Tor.

So is there any reson to justify existance of any of these services? Freenet provides storage which doesn't depend on goodwill of any corporation, if content gets popular distributed network just makes more copies. Anonymous nature of network allows anonymous publication of information that you might despise and might be illegal. Only way to defend against distribution such information is to not to look for it. That doesn't stop others distributing it though, but at least parts of those files won't so easily end up on your computer.

It's quite interesting point though, if goverment tries to ban some material on Freenet, they end up making sure that it's available by requesting it. Publisher of the information is impossible to find, unless information itself has some clues.

All three prevent anyone knowing who do you contact by using traffic analysis. Normal SSL connection to your bank protects anyone from getting the information you are transmitting, but somebody who can capture the message knows where it is coming from and where it is going to. EFF (organization that has developed Tor) has actually good overview why we should protect ourselves against traffic analysis.

Is the world better place if any kind of information can travel free? Or should these networks be banned altogether as they can be used to distribute highly unmoral material? Or is world now in such state that there are some things that can't be discussed unless it can be done completely anonymously? Of course that depends on where you live in, but are things getting worse in western world too which is considered free (or at least from western point of view)? Or are all people using such networks criminals?
