After installing it: $ ssh -Y fbsd81 'echo DISPLAY=%$DISPLAY%' /usr/local/bin/xauth: creating new authority file /home/perryh/.Xauthority DISPLAY=%localhost:10.0% and -X also works :) so this turns out to have been the solution. Next question: shouldn't I have gotten some kind of error message when attempting ssh -X or ssh -Y when xauth wasn't available? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Have you tried putting: DISPLAY=:0.0 in ~/.ssh/environment on the machine that's not setting DISPLAY properly? Wouldn't that cause the remote app -- which is running on the ssh server -- to (try to) use that machine's own local display? A port-forwarded connection normally has something along the lines of DISPLAY=localhost:10.0 (but it can't be hard-coded, because the 10 part will vary depending on what-all port-forwarded connections exist). ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
