set your firewall so your only servers that can hit the Internet are on port 21 (ssh)
Port 22 is for ssh. 21 is FTP (and 20 if I recall correctly).
Dohhhhhhh! A simple grep ssh /etc/services would have told me that. But nooooo, I went and shot my mouth off. I've never enabled ftp or telnet on my own computers, at least on Linux. Since about 2005 I never used them as clients either. Passwords aren't cheap, and neither is my (or anyone else's) data. SteveT Steve Litt http://444domains.com
