Telnet / Postfix connection refused question for CENTOS 6.4
Good Morning! I am supporting the coffee and Doritos industry with my frustration with this problem. I have been battling it for two months. I have several Red Hat books, the official Red Hat study guide, and have searched the forums for weeks with no avail. I was wondering if you have ever had this?
I am trying to "telnet server.example.com 25" or telnet in general. Both servers are running on a KVM on the 192.168.122.0/24 network.
So I did a reboot, and now it works. I have rebooted literally hundreds of time over the past eight weeks, so I'm not sure why today is the special day, but I can telnet and use postfix on port 25 without a firewall on. Now I will turn on IPTABLES and make sure that works. The only thing that I can think is that my BIND/NAMED hasn't been configured, and I am setting up my DNS wrong. Thanks again for your time!
