I use the winexe (a samba-based tool like psexec) to run a command remotely on windows targets. The problem is, sometimes it hangs until interrupted and I'd like to put it in a cron job. So I added a 'timeout 80' on the command line that starts a shell script that invokes winexe with the needed parameters. This does prevent the hang, but now every run takes the full 80 seconds to return where it should average 5 or 10 seconds on a normal execution - and it seems to trap normal interrupts until its own timeout is reached.
Timeout seems to return immediately when other commands exit. Am I missing something obvious that might make it wait in this scenario?
Strace show a loop of these filling the time after I think it has completed: ioctl(0, SNDCTL_TMR_START or TCSETS, {B38400 opost isig -icanon echo ...}) = ? ERESTARTSYS (To be restarted) --- SIGTTOU (Stopped (tty output)) @ 0 (0) --- --- SIGTTOU (Stopped (tty output)) @ 0 (0) ---
