SSH connection suddenly stop

English Network/Internet
#1

Hi,
I’ve an issue with ssh connection.
I’m in my intranet and from my PC (LEAP15) i can connect with ssh to a PC with opensuse 13.0 (no firewall) without any issue.

Now I’m setting up a new PC (LEAP15) always on my intranet and ssh connection is very problematic. Connection started without any issue and always stopped within 1 or 2 minutes.
I’ve tried also to disable the firewall but the result is the same.
This is what I do:

  • open konsole on my pc and as normal user i run : ssh remoteuser@ipaddress (connection started succesfully)
  • i give the remoteuser password and i switch to su with root password (root of remote pc)
  • suddenly within 1 o 2 minutes the connection freeze …

All network connection are hardwired (no wifi).

What can I check / do ?

Is there any rule (maybe in polkit) that can block ssh ?

Just for knowledge the new PC is a HP Proliant microgen 10 …

After further investigation I’ve to change my diagnose : the culprit isn’t ssh but is the remote ‘graphic’ server.
Applications that freeze (and often, after 15-20 seconds restart) are yast and mc, ssh shell is perfectly working …

Thanks for that update. Now you have a different problem to solve :frowning:
