UNIX Monitoring & Limitation of Sessions

[Vassilios]

Hello,

How can I limit the number of hosts connected to a UNIX server?? The problem is that too many XSessions seem to be taking up a lot of space/processing power on the server, and it causes it to crash.

Secondly, what can be done to "monitor" performance of the UNIX server?? I've done a top command - this is useful,but we need something more "detailed" to tell us how much resource is being taken up with respect to bandwidth utilisation and CPU capacity.

Thanks for your assistance

I will suggest using Glance Plus for current utilizaton and it provides the detailed ouputs for the processes and other system resources.

hi,

to limit the number of session per user modify "NUMBER_OF_LOGINS_ALLOWED " parameter in /etc/default/security file controls If the file doesn't exist, or the parameter is not present, there is a default value of 0, which doesn't limit the number of concurrent sessions.


chek parameters npty in kernel parameters

For second, use glance , sar or vmstat
