FWIW I tunnel just about everything at work eventhough I am the "cops" here and have access to every outbound firewall rule. The IM services are inherently insecure and vulnerable MITM attacks so I use SSH to encrypt all of the non encrypted traffic. Here is a primer on how to get started. http://souptonuts.sourceforge.net/sshtips.htm and a list of free shell servers out there... http://www.red-pill.eu/freeunix.shtml BTW you don't have to be a UNIX junky to set up a tunnel...Putty makes it easy http://www.chiark.greenend.org.uk/~s.../download.html some more links... http://en.wikipedia.org/wiki/SSH_tunnel http://www.engadget.com/2006/03/21/h...etwork-access/ Also, you don't necessarily need to have outbound 22 enabled, you can tunnel virtually through anything, including corporate proxies, but that is another lesson Oh and I almost forgot... You need a list of anymous proxies out there for your (ab)use. http://samair.ru/proxy will give you thousands upon thousands of open proxies to pick and choose from. The site will undoubtedly be blocked by your proxy filtering softwar (smartfilter probably) so sign up for a free shell account and wget that page and copy it back down to your localhost so you can view it in notepad. You can also use a program called TOR (The Onion Router) to get out on. Recent improvements on the client will allow you to easily tunnel over port 80, 8080, and 443. The traffic is "anonymous" but the encryption is suspect because you don't control the ciphers so I tend to stay away from it. http://www.torproject.org/overview.html.en Once you get advanced try out your own SSL VPN back to your home machine and bounce a proxy off your home network. Check out openssl.org for more details on that. Last edited by toofasttooslow; 11-28-2007 at 02:56 PM.. |

Yes, but I guarantee they've all been found already by SmartFilter or whatever your IT's choice URL filtering software is. I often think about setting up a web proxy on my shell server ( I already have squid running and it would be trivial to set up a simple redirect page) but it would get abused by all the Chineese and botnets out there.
