Hi, I would like to briefly comment on a problem mentioned in the file "TODO" and also in the OpenSSH FAQ (question 3.10), namely the hanging of an ssh connection (on Linux) if there are active processes. It is stated that this has to do with the fact that children of the shell are not killed upon exiting the shell. However, the problem also occurs if a process is started with

Hi, we are running samba 4.4 on two machines as file servers. Both are running a GFS (stornext). The storage is attached using 8G HBA. You can get up to 800MB/s local speed. We are exporting the shares using 2x1GB and 2x10G. However the clients are only getting 40-50MB/s. With samba3 I think we had up to 80-90MB/s. Using a 100MB/s link for the client we see 12-13MB/s (wire speed). Using

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

The hang on exit has become quite an issue in my organization(Sun and HP hosts). I see this note in the changelog which indicates that there will not be a fix for this problem: 20001129 - (djm) Back out all the serverloop.c hacks. sshd will now hang again if there are background children with open fds. Also, I am aware of the workaround as noted in the FAQ. However this workaround is not

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,
