Ssh

i just installed RedHat Linux 7.3 and it has the SSH daemon running but I can only log in to the SSH from the same computer and not a remote one thats on the same local network. Is there a security setting I have to reduce or ???

The firewall is probably running as well and is setup to now allow any traffic on the ssh port. Just to see if that's the problem, as root, type this:



Then try your ssh connection from a different machine. If it works then, you'll need to open a hole in the firewall to allow ssh connections. I don't remember how to do that exactly, but just look at the man pages for ipchains, it's all there.

After flushing it, how do I restore it to just remove the SSH port from being filtered?

I uncommented the thing that was disabling listening on port 22, now how do I restart SSH without having to restart my computer?

To resore the firewall rules, you can run this command:



and to restart sshd, you can use the `service' command:



Both those need to be run as root.

I flushed out ipchains but I know that's not the best way to go about things because now I have no firewall. I want to restore my firewall but how do I only remove SSH from the ipchains list?
