Thread: Cannot SSH directly into server

OS: RHEL 2.6.18-238.el5PAE

I cannot ssh directly into this box from a different.

I can ssh from another server on the same network but i cannot go directly to this server from an outside network.

I hope this make sense ....

Your help appreciated.

Many reasons can block it. A few I can think of it:

• Firewall
• Hots security config (/etc/hosts.allow or /etc/hosts.deny)
• Routing
• Vlan
• PAM config or sshd config

Take a look at server logs (both firewall and sshd logs).
