Server to Server SSH not working -- Need help troubleshooting please.
Server 1: Up and running for a while
Server 2: Just setup
I've just finished installing a new instance of CentOS 6 for Server 2 (which is the same OS as Server 1). The purpose of Server 2 is to have a backup server that I can remote sync my server backups to.
I can successfully SSH into Server 2 from my home computer.
When I try to SSH in FROM Server 1, it times out.
I have checked the firewall (CSF) and whitelisted the IP address of Server 1.
I have turned off the firewall temporary to see if that was the issue.
Both aren't working. I did create SSH Keys on Server 2 and used ssh-copy-id to get those keys to Server 1. That was successful.
Now, when I go to ssh in, it just times out. No password prompt comes up.
I've tried using the -vvv option with SSH and all it does it time out while trying to connect to Server 2.
Can someone please help me?
