Restart service problem with sudo

[Andy Shellam]

Hi Sil

I had a similar problem with NRPE - an NRPE check worked fine when doing 
it from the command-line, but it refused to work from the NRPE itself.

I eventually found out that my /etc/sudoers was denying anything without 
a terminal from using sudo.
It might be the same problem, might not, but check your /etc/sudoers 
file does not have a "defaults requiretty" option set - if it does, 
comment it out and try your event handler again.
