I downgraded one of my computers to 15.2 because this is the only way to have a sound. After my NFS server problem has been solved now, I have one more problem, i.e. I cannot access to this computer, called "pachew", by ssh. When ssh is invoked from outside, no prompt for a password appears, but any connection is immediately refused, and this error message appears: "ssh: connect to host pachew port 22: No route to host" Any suggestions? Thanks in advance, Wolfgang

What does that mean?
"ssh: connect to host pachew port 22: No route to host" Any suggestions?
1. ping pachew 2. host pachew 3. and check out ~/.ssh/config if you have something there for the ip-number or the host pachew probably not meaningful as you have no route to it but anyway: 4. ssh -v <ip or name> -- /bengan

a) Can you ping that host? b) is sshd running ? c) firewall ? -- Per Jessen, Zürich (20.7°C)

a) Can you ping that host?
Yes, ping works correcty.
b) is sshd running?
No, neither is sshd running, nor is it available in Yast nor can it be downloaded.
c) firewall?.
The firewall is off. Regard, Wolfgang

Yes, it can be downloaded, just search in yast or zypper. The rpm name is "openssh". Next time, look carefully during installation at the bottom of the summary screen, that ssh is not enabled/installed/open, and activate it. -- Cheers / Saludos, Carlos E. R.

You do have it, according to zypper. systemctl --now enable sshd.service -- Cheers / Saludos, Carlos E. R. (from oS Leap 15.2 x86_64 (Minas Tirith))

This last command made it. Now, ssh works without groans. Thanks a lot y tantísimas gracias, Carlos! Wolfgang

Good, it is selected by default, so it would have been quite odd if you didn't have it. Next is to check that it is running - a) ss -ltn (you should see something listening on port 22) b) systemctl status sshd If it isn't running, follow Carlos' suggestion. -- Per Jessen, Zürich (22.4°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland.
