Changes

Upgraded to OpenSSH 3.8

Cause

As a change to previous releases, OpenSSH is now using untrusted X11 cookies by default. This is documented in the 3.8 release notes.

Fix

The previous behavior can be restored by setting ForwardX11Trusted yes in ssh_config in the user directory on the host.
