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.
