If your user's name is Billyfoo:


 # Host alias specification
 Host_Alias     LOCAL = 127.0.0.1

# User Specifications

Billyfoo     LOCAL = NOPASSWD: /etc/init.d/crond

That should do it.

Whups.  Edit got cut off --

You'll need to change the LOCAL value to the host name or IP address of the allowed hosts. But otherwise, that should do it.

I did that, but when I run

www> sudo /sbin/service  crond restart

I get this error:
sudo: must be setuid root

I used visudo to make a /etc/sudoers, which looks like this:

Host_Alias     LOCAL = 127.0.0.1
root    ALL=(ALL) ALL
www     LOCAL = NOPASSWD: /sbin/service crond restart

What am I doing wrong?

 

by: kblack05Posted on 2006-09-01 at 07:04:59ID: 17437062

Sudo must be setuid root to do its work.  You need to do something like
   `chmod 4111 /usr/local/bin/sudo'.  Also, the file system sudo resides
   on must *not* be mounted (or exported) with the nosuid option or sudo
   will not be able to work.  Another possibility is you may have '.' in
   your $PATH before the directory containing sudo.  If you are going
   to have '.' in your path you should make sure it is at the end.
