When I encounter the problem with TCP port forwarding locking up, I'll see this on the client window (if I haven't invoked ssh with -q): chan_shutdown_read failed for #1/fd6: Transport endpoint is not connected chan_shutdown_read failed for #1/fd6: Transport endpoint is not connected This is with Blowfish encryption. I have to kill and restart the client when this happens. Phil

I am running OpenSSH 2.9p1 on SunOS 5.7 w/4-24-2001 patch cluster. Like many other users I am seeing the hanging session on logout with background processes. This is a huge problem for me as I centrally manage 50+ machines with rdist across ssh. Instead of just complaining about the problem I thought I would put my CS degree to use and try to track down the problem myself. For starters,
