[mrtg] Re: crontab & MRTG emails

[Andrew Hull]

Shane,
My solution did not use cron, but it achieves the desired results. I 
used a ".forward" file in the user's home dir that runs MRTG.


[mrtg at tbx mrtg]$ cat .forward
\mrtg  		 # This keeps a copy in the local account also
user at domain.com  # Address to send mail to


Just create your own version in the home dir of the user that is running 
MRTG and that should do it. Permissions should be -rw------- (600).

Disclaimer: It is possible to configure Sendmail so that it ignores this 
file, and the uber-security-minded may prefer it that way.

Check out

for a .forward tutorial; google has many more also.
