[mrtg] Re: Dynamic IP

[Mike McCandless]

I looked in the config file.  By "told MRTG to query the box with IP
address a.b.c.d" does that refer to the value in the line:

SetEnv: MRTG_INT_IP = "a.b.c.d", etc.  ??

That's the only place I can see that I have defined any IP address,
related to MRTG configuration.

By the way, I have an Internet-facing NIC and a LAN-facing NIC.  I'm
interested in the Internet-facing one, which is the one that has the
periodically changing IP address.
