Problems with SSH and IPtables

g_paschoal · 08-01-2011, 11:27 AM

Guys.. I have 2 servers..
let say server A and server B

On server A open ssh is configured and is running on port 2298. So from my machine I can login there using ssh on port 2298

but when I login to server B and from there I try to connect to server A I cannot.

ssh: connect to host <ipaddress here> port 2298: Connection refused

can someone please help me?

thanks

Hello,

That's because you only have one computer/server configured for ssh. Configure your other server for ssh, and make sure you configure iptables to open the needed port to gain access.

Cheers,

Josh

When I get it right, a login via the usual port 22 succeeded already on machine B. Is there anything in /etc/hosts.allow or /etc/hosts.deny on machine A which would block access for certain addresses? Another file to check could be /etc/ssh/sshd_config whether there are any address limits exposed.
