I don't have to tell you that I am new to *nix.
I have three doubts in my mind reagarding configuration of server.
If someone don't have the physical access to the computer.
Is there any way or command in telnet through which we can check what is the processor speed and brand of the processor.
Like how can we find out between brand and CPU speed.
Celeron 800
Pentium 800
Amd 800
all the above processors are of 800Mhz?

How can we check if ram is working fine in server or not. And how can we increase the virtual memory?
How to find out if the HDD is SCSI or IDE?

to check the proc speed and get info type "cat /proc/cpuinfo"

Most installations have a program called top which will allow you to monitor your memory usage. As well you can CAT another file from /proc out to the screen but its not near as helpfull as top because top updates the info.

To check if a hard drive is SCSI or IDE you can look in /etc/fstab and see what device it is if its /dev/hda1 or /dev/hdaX or /dev/hdbX then its IDE if you are seeing /dev/scdX then its SCSI. You can run hdparm on the devices and get even more info on the drives such as CHS and serial numbers and the like. Also to check HD size and usage you can use "df -h <drive name>"

Hope this helps....

I got this

Filesystem 1k-blocks Used Available Use% Mounted on
/dev/hda1 4492448 593124 3668924 14% /

For HDD.
Is it SCSI or IDE

hda is IDE, as he said in his reply...

"To check if a hard drive is SCSI or IDE you can look in /etc/fstab and see what device it is if its /dev/hda1 or /dev/hdaX or /dev/hdbX then its IDE if you are seeing /dev/scdX then its SCSI."

What is the processor speed here

processor : 0

How to run hdparm like this
#hdparm

and how can I check the RAM and VIRTUAL MEMORY of the server.

That processor above would be a Pentium III, 800 mHz. For checking RAM and virtual memory (swap space) try this command:
free -h
Hope this helps.

Sorry, that free command is this:
free -m
It prints out stats on memory in megabytes

idiot am I. When I said 800 I meant 850.

Get following results. But I have one question. How can we increase virtual memory to get max of the RAM

free -m
total used free shared buffers cached
Mem: 384 54 329 0 0 0
-/+ buffers/cache: 54 329
Swap: 0
