Proxy Bypass

by on Jan.10, 2006, under How To ..., Linux, Software

I guess it’s usual for every institution to have a central firewall/proxy that all internal traffic must go through to reach the outside world. I am by no means paranoid about security/privacy but it got me thinking.

… And once again, SSH to the rescue! It almost feels like the possibilites of a SSH tunnel with Local port forwarding are limitless 😀

I just picked up a public German proxy from this page:


And then setup a SSH connection to forward local port 8080 to proxy:port. Then for the browser I just set localhost:8080 as the proxy.

Well, the speed is a little short of astounding but it’s very much usable 😀 Now all that the central firewall/proxy should be seeing is a bunch of encrypted traffic.

VPN from Linux (x86_64)

The Cisco VPN client doesn’t seem to compile on the 64bit architecture. Well, open source to the rescue .. behold VPNC. Since the Cisco profile files are no good, I needed to decrypt the group password – which was a piece of cake thanks to the password decryptor on the site. They say it’s done through the command:

# ltrace -i ./vpnclient connect ... 2>&1 | fgrep 805ac57

I’ll try it for myself sometime.
