HELP NEEDED: Linux gods please help

[haryanto]

Hi guys,

I really appreciate all the help I got from you guys for the past few months. Just wanna say thanks!

Anyway here is another problem of mine(I never seem to run out of it):

Is it possible to configure linux in such a way that it is impossible for end users(hosting clients) to find out about the hardware profile of my server?e.g.RAM,Hard Disk,CPU.

Ok, but you'll have to sacrifice a penguin first. Just joking.

Maybe just "freezing" all the applications that allow recovering those data, it is, do very strict chmods to du, top, memstat, the whole /proc tree, etc. If the user can't run the commands or access the data then most probably can't find out anything about the hardware.

Of course there are still perl and company where the user is able to install its own scripts. If some script needs data from /proc it'll bomb and your user may get angry. I'd study first the possible consequences. Maybe not the whole /proc needs to be blocked; I've just pulled this answer out from the magic horned helm, more analysis is required.

Is great from blocking processes, without restricting all /proc for users but work on it has just been discontinued but it still should be what you are looking for.

regards,
Mark
