Even without a concrete use case, I agree that it's absolutely imperative for the standard to require this of a conforming implementation. It's going to be the source of so many problems otherwise On Fri, May 12, 2017 at 9:14 AM Hal Finkel <hfinkel at anl.gov> wrote: > > On 05/12/2017 11:00 AM, Scott Smith wrote: > > On Fri, May 12, 2017 at 12:52 AM, Bryce Lelbach

I thought the executor is a hint, not a requirement (certainly the standard doesn't say it has to execute on

Perhaps this is a known problem, but I only found one instance of someone describing it on the net with no follow-up. I just installed openssh (3.6p1) on a linux system (running an old 2.0.34 kernel) with privilege separation disabled and get the following messages in /var/log/messages: Apr 2 15:48:34 ernestine sshd[6153]: error: ioctl(TIOCSCTTY): Operation not permitted Apr 2 15:48:34
