I believe this behavior is intentional. Using ssh under solaris exhibits the same behavior. I don't entirely know the reason but I'll take a wild guess and say that as long as the child process is attached to a tty, ssh won't let go of the parent. I suspect if you can make the child process both disown itself and detach from the tty, you should be set. Something like this might work (bash, sh) ls < /dev/null >/dev/null 2>&1 but I'm not sure. ttys are a bit on the black magic side. Installing and using screen, as someone suggested, also works. I hate screen though since it interferes with my emacs keybindings and I'm too lazy to reconfigure yet another program. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
