[mrtg] Can't add any devices with cfgmaker

Thanks Lyle,

I did  "cfgmaker --output /var/www/mrtg/
public at"  and got the cfg file.  When I run indexmaker on
it "indexmaker /var/www/mrtg/ >

I get a page, but that has problems. It looks like it tried to create a
graph for each interface it found. It looks as if it tried to create a
page /var/www/mrtg/, and etc
etc, but there aren't any files anywhere. The
hyperlink looks right http://myserver/mrtg/  


Does it appear like I still don't have the cfgmaker right or is it
something with indexmaker?





What is a good way to organize many devices?  I was thinking of building
a cfg directory under the mrtg. It looks like each device will have many
associated html files and that could get complicated.  Then perhaps one
master page with a link to all the individual pages I've made with
indexmaker.  What did you do?

It seems to be working fine.  I added my local linux with

That is running just fine, updating every 5 minutes like it is supposed
to.  I want to add more devices now but I get an error.  I try 

Cfgmaker public at > /etc/mrtgtry2.cfg


It runs a bit then tells me

I can run snmpwalk and get info back:

Cfgmaker seems to want to replace the IP addr of the device with the


Am I doing something simple wrong?

Thanks in advance.



cfgmaker public at -output=/etc/mrtgtry2.cfg

cfgmaker thinks the second part is a second device to poll.
