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.

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

See the VPN page for information on connecting to the Virginia Tech VPN.
