Adding hosts to the xhosts list permanently

[cyborg]

Is there a text file anywhere, where I can add some hosts to so that I don't have to keep doing `xhost +host`? I thought it was meant to be /etc/X0.hosts, but I don't have this file (do I need to create it?).

Using xhost is a security nightmare - you open your X server to ANY process on the designated host.

This is maintained only by the X server, and is only usable when the TCP socket is enabled. This allows the server to fail secure if the X server is restarted. The problem using a /etc/Xn.hosts file is that EVERY user of the designated display can get unauthorized connections.

Another problem is that the X server doesn't just use "X0.hosts", when user login switching is used, you can get "X[0,1,2,...40] (I've seen 40 on my system), making maintaining the file unreasonable.

Normally, the X server has TCP connections disabled.

Use ssh to tunnel X protocol securely. Easier, and doesn't require any work.
