Unable to set non-blocking on pty

飞天二狭

We have xp1000 workstation running Tru64 Unix 4.0f and are having the following problem.
I can log onto the system via CDE successfully. When I try to open a
terminal from desktop, I get the following error
Unable to set non-blocking on pty,why?
thank you!

What I can figure out is two possibilities:
1. you log on to the system via CDE as superuser (root), and
cannot log in from the desktop. If in this case, add ptys to
/etc/securettys
2. the machine might run out of available pty lines. use this
command to see the number of pty lines.
# sysconfig -q pts

There are other possibilities beyond me.

hope this helpful.
