I have a problem. My server PC is down (taking it to the shop on Monday when they open) and I wanted to transfer the sendmail settings from the server PC to my client PC. The server was running RH9 and the client runs Fedora Core 1. Anyway, I've altered my /etc/sysconfig/iptables to allow port 25 and 110 access (SMTP and POP3) and restarted iptables, but it won't allow access to port 110. The Fedora Core iptables file was a little different from RH9, but I think I've got it right. Here are the relevant lines from /etc/sysconfig/iptables:
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 25 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 110 -j ACCEPT
I can telnet to 127.0.0.1 25, but not to 110. When I try to telnet to 127.0.0.1 110 it says:
[root@baby mail]# telnet 127.0.0.1 110 Trying 127.0.0.1... telnet: connect to address 127.0.0.1: Connection refused telnet: Unable to connect to remote host: Connection refused
When I telnet to port 25 I get this:
[root@baby mail]# telnet 127.0.0.1 25 Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'. ^]
telnet> quit Connection closed. [root@baby mail]#
I don't know what I'm doing wrong. Please help! Until I get this fixed I have to rely on the central.coxmail.com server, which is hardly reliable at best....
