New users can't login to one of my server . The cause is that freed ttys
are not re-used for new connections. Some users use Exceed.
Adding more ttys is a good way to solve this problem..

Any suggestions would be very much appreciated.

There isn't a question here.

If you're trying to release the pty's, look for processes. If, for
example, /dev/pts/12 were in use from an old session, do this..

/usr/ucb/ps -t pts/12

That will report all processes associated with that pty. Killing them
(or finding out why the're not dying automatically) should return the
port to use.

If you're interested in increasing the number ptys available to users,
see the Solaris FAQ.

Gack! "/bin/ps -t pts/12" would have done just as well...

It will report all processes with that pty as controlling terminal. It's
possible to have a pty open without it being the controlling terminal,
and this will also prevent the pty from being reused. To find such
processes. use

/usr/sbin/fuser /dev/pts/12

Frick. Why couldn't I find that when I looked at the man page the first
time? I thought it was there, but in my haste to post, I reverted back
to my BSD days...

Excellent idea. Normally when dealing with 'stuck' ptys, I can find
them all with a ps, but the fuser command is more general.
