SSH Frequently Asked Questions

With OpenSSH, X forwarding works for some applications, but not others!

---

The programs that don't work may be using a broken or old version of Xlib that doens't pay attention to the XAUTHORITY environment variable. Try:

cp $XAUTHORITY ~/.Xauthority

Note that you may transmit your xauth key in cleartext over the network by doing this if your home directory is remote; avoiding that is part of why OpenSSH keeps them under /tmp to begin with.
