I have a router that is configured via a web browser (It's a Netgear).

I need to change the port forwarding options now and again, and so would
like to write a script to do this automatically, then I can just run the
script rather than firing up a browser.

I figure if I strip out the necessary HTML to make the changes (eg,
everything in the form) and submit this to the Netgear's port 80 (Along with
my login credentials in the form), this would make my life easier.

My query is, what could I achieve to do this.

Say I set up a couple of HTML files with the form data in, how could I
submit that? If I put something in the script to "lynx form.html" it'd only
display it on the screen, not submit the form as well.

Anyone achieved something similar to this before?

You wouldn't strip out the HTML, but figure out what POST parameters the
Netgear wants. You can then use the Perl LWP modules to post that data
to the Netgear. These issues are all offtopic here, so I suggest
finding a CGI or (if you start coding in Perl) a Perl forum for your
questions.

Here you are complaining about an off-topic posting and yet you are
using pgp which is against the policy of this ng.

I would think you should be able to do that via SNMP try net-snmp
( maybe from: http://linuxpackages.net ) for that.

You could probably look at a valid connection (dumping the payload
with "ngrep", "sniffit" or some such) and script some ol' hackery with
"socket" or "nc" (netcat) ...

Try the "-auth" and (maybe) "-post_data" flags to "lynx" -- man lynx .
What ever you do though, it will probably take some coding.

Maybe have a look at the scrips used for dynamically updateing DNS
records and modify them (if SNMP isn't available). Such as the "clients"
for dyndns.org

Agreed.

Wouldn't a CGI (common gateway interface) be server-side scriting -
in this scenario: on the router?

Or, "expect" some "telnet" trick :-).

Not all routers support SNMP. I don't believe my Netgear ''router''
does.

See below.

Well, the router has some sort of CGI program that processes the POST
data from the web browser. It is helpful to know how parts of an HTML
document will be processed by the CGI on the other end (or, at least,
what keys and values the CGI expects). But you're right, no particular
CGI knowledge is really needed; knowing which HTML tags will be
processed by the CGI is more important.

Ewww.

But doesn't the use of pgp interfere with SNMP? Perhaps you might
consider using pgp in a responsible manner in the future. We would
sure appreciate it.

For newsgroup searchers: No it doesn't interfere with SNMP, just our
resident anti-pgp troll :P

Really, I'm not out to destroy Microsoft. That will just be a completely
unintentional side effect.

There are several hundred "anti-pgp trolls" and we bring this issue
to light on their behalf.

Please refrain from the unwarranted use of pgp. It violates this
ng's policy, it violates our sensibilities, and it violates common
sense.
