Problem of X11 forwarding

Problem:

When connected using the -X or -Y option with ssh, the following error is reported.

/usr/bin/xauth:  timeout in locking authority file /home/<user>/.Xauthority


Cause:

It is in fact caused by incorrect SELinux setting.


Solution:


# ls -alZ
drwxr-xr-x. uid gid   unconfined_u:object_r:home_root_t:s0 <user>
# chcon unconfined_u:object_r:user_home_t:s0 <user>
# ls -alZ
drwxr-xr-x. uid vid   unconfined_u:object_r:user_home_t:s0 <user>

Then login again, the xauth will create the .Xauthority automatically.
