Re: User noboby and permissions...how and why

[Robert Canary]

nobody is just that "nobody" it is a user who 
doesn't exist and they are the lowest man on the 
chain of command.  Most damons will run as nobody 
for the porpose of *not* giving the application 
any access to any resources (none whatsoever). 
Simply do their own thing and not interfer with 
anyone elses stuff.

List,

I'm learning about low-permission and restricted users and groups. I'm 
curious about users like "nobody" and groups like "nobody"

What does a user like this look like? home? password? etc.

I have seen a user report recently showing the nobody user in Mac OS X 
as something like:

name: nobody
group: nobody
home: /dev/null
password: ?
shell: /sbin/nologin
I have poked around on the Internet, no good sources turned up 
explaining users/groups like nobody:nobody in detail, like how and more 
importantly "why". Hoping the list might have some insight as well as 
suggested best practices for creating a similar user/group for processes.

Thanks,
Tim
