Re: No of users login >26, Urgent!

[Shailesh Vidyarthi]

Hi,
Our unix server is HP9000/E35,having HP-UX version 10.01 B. On this Sybase 11 runs. It is in a netwoked environment, connected to PCs, over 100Mbps switched NW, protocol is TCP/IP.
The problem is when no of users are 26 or so ,further login from PC to the server is not permitted. Message comes as "Connection reset by host" or the pcs do not connect to the host above.
What should we do to enable more no of users-login ? Thanks in advance.

Shailesh,

This looks more likely like a kernel parameter overflow.

When you get a chance try check and increase npty and nstrpty values. Or could be related to nfile as npty or nstrpty will give out errors about /dev/tcp.

Or you can do an insf -e before increasing these values.

But I would check syslog file to determine the problem along with dmesg command.

Hi,
Please check your console/syslog file for the reason not able to login >26 user.
As sridhar suggested check for the kernel paramaters npty,nstrpty,maxuprc,maxusers etc.
How many user license you have installed?
Do uname -a to check.


best of luck

Hi,
seems to be purely kernel parameters values, have a look at maxusers, nptys. In u r case it looks like these values are set to 26, increasing these nos will solve u r problem.

Hi

I think this is because of npty only. U can install this by using insf command. for more information see the man page of insf.

Please chack ur kernel parameters also. I am attaching one file here, which will help U to tune kernel parameters.

Best of luck

Hi,
maxusers = Value of MAXUSERS Macro (Does Not Affect Max. User Logins)
In this case maxusers may not be the culprit.
