Subject:   SSH XForwarding Failure
Message-ID:  <1233958699.9335.6.camel@patrick-laptop>

next in thread | raw e-mail | index | archive | help
I have absolutely no clue why this isn't working. xauth is installed
$DISPLAY is localhost:10.0 XForwarding is enabled in sshd_config and I
invoked ssh with -X.
