I was wondering if there is a script that I can upload to my webhost that would allow me to know the specifications of my webhost's server that I am being hosted on?

This is because I just want to verify what my webhost telling me is true. I want to see what type of server (such as the Mhz, the RAM, etc.....)

If there is such a script, can you give me the URL to where I can get it. Thanks.

You should try phpSysInfo...

It shows a decent amount of data about the server you're running on such as ram, cpu, some hardware, etc.

Nice little script.

phpSysInfo (http://sourceforge.net/projects/phpsysinfo/)
