/usr/bin/mosh: Did not find mosh server startup message, mosh is available in path

[Nikola-Milovic]

Hello everyone, I have installed mosh both on my server and my client, and they seem to be working fine, but when I try to connect remotely it just doesn't work. It says that the server is not in the bin, but from the output of the logs below I think it is

That is not how the --ssh arg is supposed to work. What happens if you run mosh nikola@nikolahome? Can you give more details about your setup? A copy of .ssh/config would be helpful.

Yeah mosh nikola@nikolahome works. It seems that I misunderstood the manpage, since I thought the --ssh specifies the ssh command and params executed to establish the ssh connection.
