Server is very slow....

[sreekanthtm]

My server is running very slow.
Telnet itself is taking a long time.....What are the things to be checked, please give the commands also.

What OS and system model?

Does the problem affect only telnet or also the slowness is for other commands after sucessfull login....

#swapinfo -tm
#vmstat 1 10
#top -s 1 -d 10 -n 50
#sar -uM 1 5
check syslog.log, dmesg....

the best is to use glance to observe what happens, is there high CPU utilization, or the memory is concerned.....

Is it only telnetting to the server that is taking time?

Ie is it taking a long time to connect or when you are actually working?

Does this affect all users or just you?

[Marcel Burggraeve · Accepted solution]

Are you sure the server itself is running slow or is it just telnet ?

At least make sure your network configuration is ok, check the following files :
/etc/hosts (hosts + ip)
/etc/resolv.conf (nameservers, domain)
/etc/rc.config.d/netconf (ip adres, gateway)
/etc/nsswitch.conf (resolving order)

What's your O/S version?
How much physical memory?

Attach a list of your kernel parm settings?
