can't open /dev/ptmx

Post by C. M. Rahman ( » Sat, 06 Jan 1996 04:00:00



Some reason when people try to telnet to my machine, I get
"can't open /dev/ptmx" .  Anybody know what causing it ? Its
been happening for a while. I like to fix this problem if
possible. I am running Solaris 2.4 on a Sun Sparc.

Thanks in Advace.

1. Unable to open /dev/ptmx:

Hi,

I run into problem like this:

When I tried to remote login or telnet to one of our server, I got:
Unable to open /dev/ptmx: no such device

I understand that it is because system run out of pty devices.

But we have pt_cnt set to 128  and currently only two users login to that
server and only 3 pty opened.

Any advice?  The server is running Solaris 2.6.

Thanks
