Hi,

I have a problem when I telnet to HP-UX running on a L2000. The message is:

telnetd:Telnet device drivers missing:Resource temprorarily unavailable

Any message will help.
Thanks

Run insf -d driver in /dev directory, check if the telnetd line is commented in /etc/inetd.conf and uncomment it. Also, there might be additional security in /var/adm/inetd.sec restricting ip addresses from using some processes.

If at hp-ux 11.xx =>

Telnet to an 11.0 session fails with "resource temporarily unavailable".

Solution:
Check to see if mksf patch [PHCO_19032/PACHRDME/English] has been installed. The problem will occur after insf has run to recreate the telnet slave device files
in /dev/pts/t*. If so, [PHNE_18527/PACHRDME/English] , telnetd patch, will resolve the problem.

These patches incorporate a new naming convention for telnet slave
devices to allow greater than 1000 telnet sessions to an 11.0 system.
The pre-PHCO_17090 convention allowed names of the form /dev/pts/t0
through /dev/pts/t999. Due to a limitation in wtmp structure, the naming
convention was changed to allow the 0-999 part of the filename to use
alpha characters, so the first telnet slave will be named /dev/pts/ta,
next is /dev/pts/tb, etc ...

If this fails :

2. Use the System Administrator Manager (SAM) to change the
'nstrtel' kernel parameter from 60 to 300.

3. Re-create the device files:

$ rm /dev/pts/*

$ insf -e -v

$ insf -d tels -n 300
