Hi List,

just a few moments ago I've read a question by a user if it would be a 
problem to run the nagios plugins with root right via check_by_ssh.

Yes - I laughed too as I read that. But in the following discussion it 
clears up - they already have a spreaded root ssh key on most of their 
systems and are to lazy to establish an unprivileged 'nagios' user on 
their systems - so they would run them as root.

I know, security awareness should be part of the persons who are using 
the tools, scripts and programs - but 80% of security holes came from 
people who didn't know what they are doing.

Without starting a flame on this topic I would like to ask what do you 
think of some security benefits like:

* don't run the code if UID is 0: Hard but effective - check uid and 
abort with a warning.
* try to drop the privileges to the givven user by the configure run as 
a hard coded option

I am not stupid enough to run my plugins with root privileges - but 
there are thousand of users out their who won't know what they're doing.
