I have an ubuntu 17.10 system(let's call it A). I want to use it from remote machines(B,C...). I have tried logging in from windows through putty and MobaXTerm and from other ubuntu machines through ssh -Y user@ip too. None of them show any error while connecting. However whenever I want to open any GUI application(from B,C..), e.g. gnome-terminal, it opens in the my ubuntu system(On A) only. But if I give the command sudo gnome-terminal it opens in the correct system(on B,C...).
P.S. I have a different ubuntu machine which is functioning properly so I copied the /etc/ssh/ssh_config and /etc/ssh/sshd_config files from there to machine A. It didn't help. Still I am facing the same issue.
How to fix this?
P.S. I reinstalled ubuntu while keeping /home as it is. Still the problem persists.
P.P.S. gvim works somehow but all other gui programs don't work. Thanks.
try editing the
/etc/ssh/sshd_configfile to add in this line:X11UseLocalHost noNotice it is setting it to no. then restart the service using
sudo systemctl restart sshd. You'll have to logon again. This is how I fixed my 17.10 system.
