I see what I've always observed,
mike@mojo{mike}$ ssh -C -X snafu.adept.org xterm
mike@snafu.adept.org's password:
<xterm pops up>
<hit ctrl-d>
Waiting for forwarded connections to terminate...
The following connections are open:
#1 X11 connection from snafu.adept.org port 2758 (t4 r0 i4/0 o16/0 fd 8/8)
If you try to close the tunnel while X sessions are active, you get
alerted of the open sessions. Otherwise, as in this case, things close
normally. This is as of,
mike@mojo{mike}$ uname -a

Haven't tried after last night's cvsup. It's probably not related, but
this isn't somehow tied into the existing Linux/HP-UX bug in the FAQ is
it?
http://www.openssh.com/faq.html#3.10
Probably not, I just knew about this because some developers complained to
me awhile back. I always thought it was interesting that under 'Why' they
say 'ssh needs to hang, because it needs to wait ...'. So why does it
only do it on certain OSs? ;)
Later,
