i changed the permissions on the folder but I still get the same errors.
Does it matter that I have both cgis (14all and mrtg-rrd) in the same
folder?  Mrtg works fine with 14all.cgi but i cannot get mrtg-rrd to work.

hopefully /path/to/mrtg1.cfg has been replaced with your actual path, e.g.
/var/www/html/mrtg/mrtg.cfg

then you have to give apache access to write the graph files, so you would
need to do something like:

chgrp apache /var/www/html/mrtg
chmod g+w /var/www/html/mrtg

That assumes that the user that runs the web browser is in the apache group.

This is what I have 

BEGIN { @config_files = qw(/path/to/mrtg1.cfg); }

and I still don't see any graphics.

I also tried

http://host/cgi-bin/mrtg-rrd.cgi/target.html 

and i get this

Error: RRDs::graph failed, Opening
'/var/www/html/mrtg/129.113.104.1_1-day.png' for write: Permission denied

What does this mean?

Thanks

You have to tell it what config file to use. Near the top of the script is a
BEGIN {} block where you have to place the path(s) for your mrtg config file
in there. 

Something like:

BEGIN { @config_files = qw(/path/to/mrtg1.cfg /path/to/mrtg2.cfg); }

In windows I guess the /path/to would be replaced by something like
c:\path\to or whatever. I havent tried this in Windows.
