ssh works only one way

Hi,
I have the following problem:
when i try and ssh into my computer it doesn’t seem to work. I am on a large proxy network. when i ping the host it is up and running and no packages get lost. I can ssh out of the machine to any other machine on the network as well as outside the network. Why am I not able to access this particular computer tho from others within the network, or even outside of it.
Any idea’s what settings i have to edit to make it accessible?
Any help would be greatly appreciated thanks
Antonia

P.S. the error message i get after a while:

ssh: connect to host hostname port 22: Connection timed out

the ping statistics are:

hostname.domain.co.uk ping statistics —
6 packets transmitted, 6 received, 0% packet loss, time 5020ms
rtt min/avg/max/mdev = 0.303/0.557/1.685/0.505 ms

Firewall would be my first guess… have you opened port 22 for Secure
Shell (SSH) in Yast?

Yast: Security and Users: Firewall: Allowed Services.

Select the appropriate entry from the drop-down and then select Add (or
just add ‘22’ under the Advanced section in the TCP field and it does the
EXACT same thing).

Good luck.

Check that host’s own packet filter settings, make sure the ssh service
is enabled in SuSEfirewall2 ( YaST / Security / Firewall ) and sshd
itself is running.

Kind regards,

Thank you so much. It is working now :slight_smile:
