I've often wondered that as well. Perhaps there's another reason for it,
but I define one sudoers file centrally on one machine and define all
rules for all hosts. Then I propagate the single sudoers to all the
hosts. I find it simpler than maintaining several sudoers files and
having to consider which sudoers file should be propagated to which

Subject: [sudo-users] Query on Host Alias

Hi Linux Gurus,

I Have very basic question, Why do we need to configure host alias in
sudoers file. My understanding is Sudo is not a centralised utility
where we
can configure privileges for all servers using one file from a single
server. if you want to configure privileges using sudo utility you need
configure on that particular server for the users on that server.

If my understanding is correct, I really don't understand configuring
alias in the sudoers file, does hot alias work as access control list
or I
am completely thinking wrong.

can anyone let me know why host alias is used and what is the purpose of
using it in sudoers file.

Thanks in Advance.
