Hello there,
I am trying to build OpenSSH on the above (very old) version of unix.
With a bit of hacking, I have managed to get everything to compile and
run. Scp works fine however when I log in via ssh I end up with a
session without a controlling terminal.
I have followed the code in pty_make_controlling_tty and it seems to go
as follows:
1. Starts with a controlling tty.
2. setsid works, no controlling tty.
3. open of tty works, however it doesn't become the controlling tty.
4. open of /dev/tty fails.
I don't have a huge experience of pseudo ttys or controlling ttys but it
looks to me like point 3 fails because there is already an open file
handle pointing to the same device.
As an aside, Dynix has a function called fvhangup (virtually hangup the
specified controlling terminal) but if I insert a call to this then all
slave terminals are hung up which seems to cause the master to close.
Can anyone offer any hints on how I can persuade my session to pick up a
controlling terminal?
Regards,
Richard Dickens

Darren, NEED_SETPRGP didn't make any difference. Still says "open /dev/tty failed - could not set controlling tty: No such device or address". Anything else I can try?
