Description Tomas Mraz 2005-03-03 23:42:51 UTC 
OpenSSH now defaults to no X forwarding which is right because using X
forwarding when ssh-ing to untrusted server could allow attacker to
gain access to the client's machine.

However when ssh is asked to enable X forwarding (by -X option or
ForwardX11 yes in configuration file) it will use X security extension
which will make most X applications break with cryptic error messages.
This makes X forwarding unusable. The option 'ForwardX11Trusted yes'
should be added to the configuration file so the -X option works as
expected enabling full trusted X forwarding.
