I ftp a lot... A lot! And I ftp to places unknown, hidden deep behind secret walls. But when I ftp on the vast plains, I go to places like sunet: they've got it all. And then some. Mirrors umich and infomac, among other things. Together with funet, this is the largest irc-server in Scandinavia. For the occult and weird, pay a visit to lysator: SF, magick, paganism, etc. Freesidei s a good place to pick up plaintext versions of Phrack. I've htmlified some issues of CUD, the Computer Underground Digest archives at University of Michigan.
For security stuff, go to spy.org. Sometimes down!For PGP & stuff Milan University's encryption site is very good. Go get PGP 2.6 without violating U.S. federal law.
But my big ftp resources can be found here. You better check it out first! Or use ftp-search on my search page!
