Telnetd again..

[rvent]

Hello...

i ve been getting anoyed with "telnetd: Telnet device drivers missing: No such device" twice in about 3 months...

The first time it happened i increased the kernel parameter for the telnet connections from the default to 80...

What else other than increasing the size would help me to deal with this...?

I belive that when increasing the parameter the device files are created which mean that resources would be used.. Am i correct...?

The application the server runs is an ERP and at the same time the database (unidata) runs on the same server. We are about to get more memory, but i wanted to get some ideas on how to handle with this instead of just adding more resources and increasing the parameter...


Thanks

Device files for telnet are in /dev/pts/t*.

Check how many you have and if it matches with the value assigned to nstrtel kernel parameter.

# ll /dev/pts/t* | wc -l
# kmtune -q nstrtel

If needed create new telnet device files with

# insf -d tels -s -e -v

Well I like to set mine a little higher to start with...and I hit all these up to 200 and increase from there:

npty
nstrpty
nstrtel

I allow it to build the device files, cause I think the default is only 60, so 80 is not exactly a big increase. You might try rebuilding your device files as Ermin mentioned too if you don't care to increase.

Just a thought,
Rgrds,
