Hi OpenSSH developers, I am using openSSH (now 2.9.9p2, but prob occurs in 2.9p2 also) to execute commands on a remote machine which outputs data to stdout then pipes it to another invocation of ssh which connects back to the first machine in the same way, where it starts a program to read and store the output from the command on the second machine. I am using the "command" option in

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,

In the changelog, there is an entry: 20001129 - (djm) Back out all the serverloop.c hacks. sshd will now hang again if there are background children with open fds. Does this mean that this is regarded as expected (and correct) behavior, that should not change in the future, or does it mean that this behavior is a known problem that someone will eventually fix? --Adam -- Adam McKenna
