telnet with port number is not working
hi,
After configuring postfix MTA on my server, not able to verify it with telnet command. Even other parameters are set accordingly. Still no success. [root@node1 ~]# uname -a Linux node1.cluster.com 2.6.32-71.el6.x86_64 #1 SMP Wed Sep 1 01:33:01 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux [root@node1 ~]# [root@node1 ~]# netstat -an | grep :25 tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN [root@node1 ~]# [root@node1 ~]# sestatus SELinux status: enabled SELinuxfs mount: /selinux Current mode: permissive Mode from config file: disabled Policy version: 24 Policy from config file: targeted [root@node1 ~]# [root@node1 ~]# service iptables status iptables: Firewall is not running.

http://www.postfix.org/BASIC_CONFIGURATION_README.html Change the "inet_interfaces" directive to be ALL, or the address of your active interface. |
iptables -L
iptables -F INPUT iptables -F OUTPUT iptables -P INPUT ACCEPT iptables -P OUTPUT ACCEPT :) If its not a configuration issue, check the firewall. |
