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

The 4.6p1 sshd is logging this error during remote commands or file transfers: error: channel 0: chan_read_failed for istate 3 Platform is Solaris 8, 4.6p1 + OpenSSL 0.9.8d. The commands and transfers work correctly, so the error message appears to be spurious. The error message does not appear when processing logins. Otherwise 4.6p1 is running without any apparent problems. This error

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,
