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 FreeBSD mojo.televoke.net 4.6-RC FreeBSD 4.6-RC #0: Tue May 21 13:06:49 PDT 2002 mike@mojo.televoke.net:/usr/src/sys/compile/MOJO i386 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, -Mike -- "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." --Benjamin Franklin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
