Humor impaired, eh? I know exactly what SNMP is, how to use it, and
what I can do with it. Since I have to deal with it at work and it's
generally unpleasant for me, mostly because of who I have to work with
to get anything done, I choose not to work with it at home. Better?

I still say many of us don't mess with SNMP at home. Maybe we should
just leave it at that.

Not to mention that snmp_request is not all that readily available for
a Windoze platform for one - and not all routers/modems respond equally
to SNMP. It would in the end be more work just trying to get the
necessary downloads done before you could get started.

Does the router support SNMP?

You can easily do it in Perl as well as the wget suggestion. If you have
Perl, I can give you a script to retrieve the web pages (we'll need to
modify it for your particular brand/model).

WG (my config page starts with) :

Config Page
Modem IP 10.22.xx.xx

So it's easy to strip the IP address from the page. If you have a
website out there with CGI, you can easily return any info you like
from the connection made using your browser/Perl/wget.

On my Linksys, I can drill right to the page that shows the status (i.e.
10.10.10.1/status.htm). The status page does show the cable modem's IP
address. However, that requires a username and password which is cumbersome,
esp. if I don't check the box to save the password. Thanks for your idea. I
will try to script something and see what I can come up with..I was really
hoping for a program that was already in circulation that would do this.
Thanks!
