Error conection user to server:

[opeador]

Hi :

Users cant't connect to my server for too many users, i changed some parm of kmtune like:
npty 120 - 120
nstrpty 120 - 120

huracan:[root]:/> who -u |wc -l
123


some lines of who:
javierf pts/ta
luciac pts/7
alejor pts/8 2:01pm susanar pts/9 2:38pm
susanar pts/10
rodrigom pts/tb 7:16am

some questions, what's the diference betwen pts/number and pts/letter? because when i reach pts/120 no more users allow login. Thanks in advanced.

Ruben.

Opeador,

Let me see if I understood your question, perhaps this can help:

"nstrpty limits the number of sreams-based ptys that are allowed system-wide. When sending data to pty devices (such as windows), a pty device must exist for every window that is open at any given time."

Regards,

Jaime.

yes, it solve 50% of my questions ;) the other is why some users got the number and other the letter...

If users are telnet'ing to your system then you must also change the nstrtel kernel parameter.

npty, nstrpty and nstrtel should all have the same value.

Hi most users use ssh and not telnet anyway parm of telnet is set to 400:

npty 120 - 120
nstrpty 120 - 120
nstrtel 400 - (MAXUSERS)
