Re: ssh

[Patrick Dupre]

Here is the bizarre thing:
from a gnome-shell
telnet 192.168.1.12 22
Trying 192.168.1.12...
Connected to 192.168.1.12.
Escape character is '^]'.
SSH-2.0-OpenSSH_8.0

Invalid SSH identification string.
Connection closed by foreign host.

ssh 192.168.1.12 22
time out

But
from a terminal (ttx)
the ssh works perfectly well!

What is wrong with the gnome environment?
