Ssh not working in thin clients?

Question

SSH

Ubuntu 16 server is ltsp set up vnc to connect to clients but I would also like ssh. On the client, you can see that the openssh-server package is installed, but I can't connect to them. Connection break writes. And from the client I can be connected to the same server. I have already rummaged through a bunch of manuals and added sssh permission to lts.conf, but all to no avail

Answer 1

Is port 22 open on the client? You can use nmap from the server to scan ports on ltsp clients.
OpenSSH server may be installed but not running.
If the port is open, what error do you get when you try to connect?
