-- Linux hangs for 20 seconds when you do "sleep 20&exit". All current
- solutions break scp or leaves processes hanging around after the ssh
- connection has ended. It seems to be linked to two things. One
- select() under Linux is not as nice as others, and two the children
- of the shell are not killed on exiting the shell.
- A short run-down of what happens:
- - The shell starts up, and starts its own session. As a side-effect, it
- gets its own process group.
- - The child forks off sleep, and because it's in the background, puts it
- into its own process group. The sleep command inherits a copy of the
- shell's descriptor for the tty as its stdout.
- - The shell exits, but doesn't SIGHUP all of its child PIDs like it probably
- should(?)
- - The sshd server attempts to read from the master side of the pty, and
- while there are still process with the pty open, no EOF is produced.
- - The sleep command exits, closes its descriptor, sshd detects the EOF, and
- the connection gets closed.
- Ways we've tried fixing this in sshd, and why they didn't work out:
- - SIGHUP the sshd's process group.
- - The shell is in its own process group.
- - Track process group IDs of all children before we reap them (via an extra
- field in Session structures which holds the pgid for each child pid), and
- SIGHUP the pgid when we reap.
- - Background commands are in yet another process group.
- - Close the connection when the child dies.
- - Background commands may need to write data to the connection. Also
- prematurely truncates output from some commands (scp server, the
- famous "dd if=/dev/zero bs=1000 count=100" case).
- Known workarounds:
- - bash: shopt huponexit on
- - tcsh: none
- - zsh: setopt HUP (usually the default setting)
- (taken from email from Jason Stone to openssh-unix-dev, 5 May 2001)
- - pdksh: ?
- This appears to affect NetKit rsh under Linux as well: it behaves the same
- with 'sleep 20 & exit'.
