We are running HP11i. We get the message "telnetd: Telnet device drivers missing: No such device
" when more then 65 users are loged in. How to can we allow more users to log in.

Thank you for your help.

Take a look at the doc KBRC00008370 ..
http://support1.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000061999596
It suggest for you to check your telnet device file and recreate them. Hope it helps.

The pseudo terminal device files have been corrupted or some are missing. Do this:

rm /dev/pts/*
rm /dev/pty/*
cd /dev
insf -e
insf -d telm
insf -d tels

This will reinstall the device files correctly. To allow 200 connections, use SAM and go to Kernel Configuration -> Configurable Parameters. Change 3 parameters:

npty
nstrpty
nstrtel

Make them all = 200 and the kernel will rebuilt to allow up to 200 connections at the same time. A reboot will be required.

Looks like your system has run out of pseudo tty's. You will need to increase the following kernel parameters if you haven't already and then run the following commands.

Kernel parameters: nstrtel, npty & nstrpty
make all say 1024

Generate new kernel, reboot your system and then run these commands.

# cd /dev
# insf ???d pty ???s 1024 ???e ???v
# insf ???d ptm ???s 1024 ???e ???v
# insf -d telm ???s 1024 ???e ???v
# insf -d tels ???s 1024 ???e -v

If you don't know how to generate a new kernel on the command line, use 'sam'.
