There is a tool to make this.......mrtg cfgmaker

 

I used this command and then edited the mrtg.cfg file to my HTML tastes......

 

/usr/bin/cfgmaker --global 'WorkDir: /var/www/html/mrtg' --global 'Options[_]: bits,growright' --output /etc/mrtg/mrtg.cfg MYCOMMSTRING@192.168.1.50

 

My SNMP config file: ((Edited for my comm strings -- mycommstring is substituted))

 

<snip>

com2sec local     192.168.1.0/24     MYCOMMSTRING
com2sec mynetwork 192.168.1.0/24     MYCOMMSTRING2

group MyRWGroup  v2c        local

I do not allow my router to pass SNMP traffic out my WAN interface, but I still setup the SNMP comm strings as non public and private.....safer...paranoid???  Don't care...safer...  :-)
