Re: telnet/pop3 question

[Antonio Galea <ant9000 netwise it>]

Hi Dave,
have you ever activated the pop3 service? It is off by default; the
/etc/services file just translates port numbers to service names.
Try a netstat to see if anything is listening on pop3/pop3s, it should look
like this:

# netstat --inet -an | egrep "110|995"
tcp        0      0 0.0.0.0:110             0.0.0.0:*               LISTEN
tcp        0      0 0.0.0.0:995             0.0.0.0:*               LISTEN

If you ask chkconfig, you should see it as well:

# chkconfig --list|grep pop3
        ipop3:  on
        pop3s:  on


If you didn't get anything, then the services are off; take a look at xinetd
config files in /etc/xinet.d/ (specifically, the files ipop3 and pop3s), and 
enable them.

Hope this helps!
