I am trying to enable ssh connection to suse linux. I have sshd service running:
peeyush@linux-pohb:~/gccgo.work> systemctl status sshd.service
sshd.service - OpenSSH Daemon

Hint: Some lines were ellipsized, use -l to show in full.
It is listening on port 22 fine:
peeyush@linux-pohb:~/gccgo.work> netstat -an | grep :22
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN
tcp 0 0 :::22 :::* LISTEN
But I am not able to connect to it.
[root@lep8a peeyush]# ssh [email protected]
ssh: connect to host 192.168.122.19 port 22: Connection timed out
My head is aching with finding solutions on internet. Nothing is working. Could you guys please help me out?
Answer
Check if your firewall accepts incoming TCP connections on port 22:
# iptables -nL | grep 22
If the result is empty, you have to add a rule in your firewall.
Open Yast and firewall configuration:
# yast firewall
Goto "Allowed Services" and add "Secure Shell Server". Save and quit Yast and try to connect.
Comment: If you have disabled your firewall completly (not recommended) this answer does not apply.
