Opening Port 110 on RH7.3

[grylnsmn]

I've been setting up an old PII 233 box to act as a basic web/mail server for my office. I've got everything working except that I cannot open port 110.

I'm using Qpopper for the POP server and have sucessfully installed it (I can telnet into it at 127.0.0.1) and I have added the pop3 file to /etc/xinetd.d/ like the Qpopper FAQ says, but port scans still do not show port 110 as being open.

What more can I do to get this working?

A port wont show open unless something is listening on it. Make sure qpopper is actually running.

Are you telnetting to the 127.0.0.1 port 110 or just to localhost. If not port 10 then this is doing nothing.

What distro/version are you using. Maybe port 110 is commented out in /etc/services(I havent seen this as a problem in any recent distro versions but its possible)

Maybe a newer distro and you chose to have a firewall running or higher security level that could interfere.

I'm using Red Hat 7.3 and popper is running (I can access it by telneting to 127.0.0.1:110). /etc/services shows that port 110 is the pop3 protocol (both tcp and udp) and is mapped to pop-3.

Check your firewalling-Red Hat had disabled some typically open ports in ipchains/iptables. YMMV.

Thanks. modifying ipchains did it.
