Unhappy
Can anyone help me, I want to be able to telnet into a server, and then show what the hardware specification of the server is. Is there a command that can provide me with a list of this.

Unix server specifications
You can get info about the CPU by doing a 'cat /proc/cpuinfo', info about the drives with a 'df' (disk free) or 'cat /proc/partitions'.

Anything specific you are looking for?

cat /proc/meminfo
Okay... you can do a 'cat /proc/meminfo' and get something like this...

Code:
[chris@corplj-linux /proc]$ cat /proc/meminfo

Try the 'top' command. You'll get info about all the things you were asking about, AND you'll get list of processes that are running.

Also if you just type in 'dmesg', you will get the the systems boot-up info, (the stuff that displays every time a system boots, as it goes through its checklist of hardware, interfaces, services (daemons) and startup scripts.

If you're not familiar with Unix command prompts, it may seem that the information escapes 'past' you out of view as new information is printed. There is a way of scrolling back to see a certain amount of this data: if you are telnetting from a windows system, you can set the scrollback buffer in your telnet client to as many lines as you want (I usually use 1500).

Also, you can pipe the output of 'dmesg' through a program that only displays one 'page' at a time, letting you step through the message by repeatedly hitting the Enter key. You would do this with 'dmesg | more' or 'dmesg | less'. ('more' and 'less' both do similar stuff )
