Security Basics: Re: SUDO vs root account question

Re: SUDO vs root account question

Tahis -

First off, the "Mr X ALL=(ALL)ALL" line will allow Mr.X to run any
command as any user on any server. So I do not know if you want to all
this.

I recently had to aid some SysAdmins at my company restrict users
access via SUDO. I found this page, http://www.courtesan.com/sudo/,
very helpful as it had an example /etc/sudoers file,
http://www.courtesan.com/sudo/sample.sudoers, that should be able to
guide you to limit users access via SUDO as it enabled me to create
the appropriate entries in the /etc/sudoers file.

Regards,

Louis
