When rshd exec()s the shell, the pipe gets closed, because it was created with O_CLOEXEC. Then logind sends SIGHUP to rshd, thus killing it and closing the rsh connection. Adding a fork() before the exec() solves the problem. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
