Linux Wireless Morals

Filed under: General Linux — TheLinuxBlog.com at 2:40 pm on Monday, April 7, 2008

Is it moral for some one who uses Linux to borrow some ones Wireless?

Lets say you are at a hot spot and you need to jump online really quickly but some the internet house your are at charges for wireless. Is it moral to connect to some one else’s wifi?

Maybe you just moved and the internet has not arrived at your house yet. Is it moral to use a neighbors for an undefined amount of time before you are settled in and have the internet set up?

If you answered yes to any of these questions then you may either be cheap (like me) or have low morals. Either way, there are ways to protect your identity and information while borrowing wireless by using Linux.

A good way to protect your self while borrowing some one else’s wireless is to tunnel with SSH. You can use a squid proxy on a port and set up your SSH to forward a local port to the squid server. Once this is done your unencrypted http traffic is now tunneled through an encrypted SSH session. If the person who owns the wireless network (or any one else) were to sniff the packets they would just see the destination address and not the full traffic information.

Use SSH for everything that is unencrypted. SSH to a known host and use these protocols here. FTP and POP are good examples of protocols that can be used by SSH. Don’t use an instant messenger through the internet, it is very easy to sniff the packets. Some times a friend may give out incriminating information which could get you in trouble.

A good device to help with protecting your information while using some one else’s wireless is DD-WRT. Once installed on a supported device it has many functions that can be used. Bridging mode, VPN passthru, advanced routing can all be used to protect your information. DD-WRT would be especially good if set up as a bridge to the other persons wireless. You could use a NAT firewall to hid how many devices you really have connected and change the mac addresses of the clients.

In the future I’ll be showing you more ways to hide your privacy while using wireless technologies so stay tuned!

Digsby on Linux

Filed under: Linux Software — TheLinuxBlog.com at 1:41 pm on Monday, March 24, 2008

I was reading this: http://www.shankrila.com/tech-stuff/digsby-is-my-favorite-instant-messenger/ post and I thought I’d check out Digsby. Other then being a really neat idea I thought it would be a great app for me to test out and see if I could use it full time. The Linux / MacOSX version is not ready yet so, I thought I’d just give running it under Wine a shot.

With a bit of struggling I did get it to work. I needed some DLL’s so I borrowed some from my Windows install. Then I needed Python, got that installed with the msiexec. Same error under wine PYTHONDLL failed to load.

Back to the drawing board, I figured I’d give that WineCVS script a shot. I posted an article about it a couple of days ago, you can use it to download Cedega and all other kinds of Wine implementations. I got the latest Wine from CVS, compiled and installed. Same issues as with the stable Wine I run. So, again battled with DLL’s (this time I just copied them over from my other install) and low and behold, it looks like it works:

Looks pretty good huh?
WRONG!

When I try to sign in with my user name it doesn’t do so well. Here is the output:

I’m not sure how much I’ll get to mess with this to see if I can get it working before they release the Linux version but I’m going to keep trying. If your interested in more detailed instructions or information on running Digsby under Wine I’ll be happy to provide that information for you.

I’ll keep everyone posted by comments in this blog post. Also, let me know your thoughts on this, and comments!
