If you happen to reside on a network that requires proxy authentication, command-line Subversion won’t work. Unless, of course, you configure Subversion to leverage a proxy correctly. If you find yourself in such as situation (as I did) and for some unfortunate reason find yourself on a bogue Windows machine (as I did, sadly) there is a file dubbed servers found deep in your home directory (your home directory in Windows is found in the C:\Documents and Settings directory and is your user name). In the home directory there is a hidden directory called Application Data and not surprisingly, in that directory, you’ll see a Subversion directory — it’s in here that you’ll find the servers file. If you find yourself in a unix-like environment, the servers file should be found in a subversion directory in your home directory.

Open the servers file and you’ll find a section called [global]. You’ll see a series of http-proxy properties that are commented out (#) — uncomment them and fill in your values, save the file, and you’ll be good to go, baby!
