Hello, I’m suffering from a ssh losing response problem these days. After about 2 mins inactivity after login, the ssh just loses responses and I have to force stop it.
I think it’s not the server’s problem because my other client machines works well.
I’m on 12.3 with gnome3.8 and following are some related output.
