I am try to remote other computer using SSH with command :
ssh -X email@example.com
but, the connected process is very slow and get the error message like this when connect to the server :
/usr/bin/xauth: timeout in locking authority file /home/alice/.Xauthority
This problem showed because the SELINUX configuration. So, we need to disable this this service. We can disable SELINUX with login in the remote machine and type in console:
Exit from the remote machine and try to ssh again. This method solve /usr/bin/xauth: timeout in locking authority file problem in my computer.
