sdm

Secure Display Manager - secure remote access to X11

sdm is an X11 display manager similar to xdm, gdm and kdm, but unlike those it wraps the X11 traffic within an ssh tunnel to provide a secure login mechanism for remote X sessions. sdm provides access only through SSH, not locally. It is technically possible to access an sdm server from same host, but probably a waste of CPU power. This package should be installed on any server acting as SDM server.
