Re: [Sheflug] Security



I used this yesterday, and found the following ports were open
to all:

21 - FTP

23 - Telnet

25 - SMTP

79 - Finger

80 - HTTP

110 - POP3

113 - Ident

Also, the remaining ports were showing closed, rather than stealth. It
looks like the situation may improve if I a) remove some services I never
use (ftp, pop, http etc) and b) set up a firewall.

Suggestions on how this is achieved (I have the HOWTO, but it is nigh on
2000 pages of plain text)

cheers,

Life would be so much easier if we 
could just look at the source code.
