There's no real difference between a workstation and a server, aside from the software that's been installed.
On an RPM based system like RedHat, you can list all of the software with the command

Code:

rpm -qa | more

You can also get a lot of hardware information by looking at the files in /proc. For example,

Code:

cat /proc/dma

will list all the DMA controllers. You can list all the files in /proc with

Code:

ls /proc | more

–note that those files whose names are numbers tell you about running processes.

You can see a list of all the open network ports with

Code:

netstat -a

(this should give you some idea of the services that are running).

Finally, if you're running Red Hat, you can change most configuration settings with

Code:

linuxconf
