Mrtg-dynip is a contribution to MRTG, enabling MRTG to generate multi

interface traffic graphs for IP interfaces on hosts that do not provide

consistent SNMP target numbers for their interfaces.  Such IP interfaces

include IP active serial interfaces attached to modems in a PPP dial in

environment. The hosts must run snmp agents.  For completeness, information

about interface devices with unvarying SNMP target numbers, such as

ethernet cards, can be configured to be included.

Mrtg-dynip can be considred to have sophisticated modem bank monitoring

capacity, when the modems carry PPP or SLIP traffic.

Regenerates a named 'mrtg.cfg' file to ensure snmp data remains with a

consistent IP number, or overridable IP number of a real physical device

in a dial in IP environment, rather than with an interface name which

can get assinged to different real physical devices, and runs mrtg on

the generated file.

Generates a web index file of stats web pages.

Mrtg-dynip's configuration is simplest where static (or fixed) IP is not

used for dial into a rotary modem pool.

The package is oriented towards UNIX systems, there is no reason mrtg-dynip

should nor run under Windows NT, some comments are made relevant to this. 

Please note the first task under Windows NT is to ensure the UNIX new lines

are converted to DOS new lines or are readable.

If you use this please let me know.  If you would also like your site to be

linked from the mrtg-dynip web page, please let me know.
