Re: telnetd
Probably you need to increase the kernel paramaters npty and nstrpty.

Re: telnetd
Check if enought devices are configured on the system:
# ll /dev/tty | wc -l
# ll /dev/pty | wc -l
Then check the kernel parameters. If the kernel value is higher then the 'll' counts then create further devices.

Re: telnetd
to Single User mode? I'm not sure it is the
root cause. Since the OS will auto shutdown
to Init S around 2 weeks. Do you have any
comments? Thanks.

Re: telnetd
I can't find nddconf since the OS is 10.20.
Can you tell how to modify NDD_VALUE in UNIX
10.20? Thanks

ALso to make your nettune changes permanent you need to put nettune in a startup script

Re: telnetd
As far as an auto-shutdown to single user mode, there is nothing that can cause this in HP-UX. init s does not shutdown to single user mode, it only changes init's run state. I would look in your cron jobs to see if init is being scheduled for some reason.

Re: telnetd
Note: The insf -e -s 400 command causes modem device types to be read-only, preventing modem communication.
Could someone tell me "-s 400" mean for?
Thanks!

Re: telnetd
-s nstrpty
Install nstrpty slave-side stream special files for the pts driver. nstrpty is a decimal number. This option only applies to the pts special file installation.
This option is effective only if the -e option is specified or if an appropriate device class or driver is specified with a -C or -d option.
If this option is omitted, nstrpty defaults to 60.
Hence -s 400 sets nstrpty to 400
hope this helps!
Best Regards

Re: telnetd
ll /dev/pty | wc -l
It shows 2010, why it is so many?
Should I increased nstrpty to 3000?

Re: telnetd
What is the value of npty and nstrpty on your kernel.
Probably you have to remove and re-install the device files.
The below document tells you how to do it.
YOu must remember that each pty device file uses 600 bytes of memory
