Proxies and VPN
Contents
Web Proxy
If you're just looking to access library resources like subscription journals, you can make use of the library's web-based proxy.
SSH Tunnel
If you're looking for a quick and dirty way to obtain a VT IP, you can run a secure shell socks proxy using a CVL (ECE) or rlogin (CS) shell account.
VPN

Using Ubuntu or Debian
- Install the Network Manager applet if you do not already have it.
