I hope this is an appropriate forum.

I'm setting up MRTG on a server, and have got it working for the most part. When you view the page, I'm getting the following at the top.

**********

I'm not quite sure what I'm supposed to edit within the /etc/snmp/snmpd.conf file, and am hoping someone can guide me.
