SSH Frequently Asked Questions
I'm using OpenSSH on the server side, and X forwarding is working fine for me... except that linuxconf won't forward, while other X clients will.
linuxconf seems to clear the environment before running subprocesses; when it calls
/bin/remadmin,
XAUTHORITY is no longer set, so the X-based front end that
remadmin starts doesn't find the proxy xauth key.
A quick solution is just cp $XAUTHORITY ~/.Xauthority before
starting linuxconf.
