What is difference between Power broker utility and sudo command.
 

Hi I just wanted to know the difference between Using Sudo mechanism over using Power breaker utilities.

Are they recommended over sudo?
Why ?

Symark Power Broker is a commercial package. Sudo is an open source tool that is included with your Linux distro.
Here's a link to a very long pdf that promotes Power Broker. Read it at your leisure, then make up your own mind! :)

Open source enthusiasts will probably shy away from it due to it being a propriety software btw.

Google Powerbrocker didn't returned Symark's PowerBrocker instead it recommended beyondtrust's Powerbrocker.
Sadly both were PAID :(
Any good free(Open sourced) alternative?

I may be wrong, but I think most people just stick to sudo.

I never tried any of these, but a quick search in the debian squeeze repos gives:

• calife: "a lightweight alternative to Sudo"
• chiark-really: "a tool for gaining privilege (simple, realistic sudo)"
• userv: "a Unix system facility to allow one program to invoke another when only limited trust exists between them"
• dpsyco-sudo: "Automate administration of sudo privileges"
• op: "sudo like controlled privilege escalation"
