[NMLUG] Minimal IP address reflector

[timothyemerick at yahoo.com (Tim Emerick)]

I use http://ipcheck.sourceforge.net/ to keep my dyndns updated as a cron job.  You could probably use this if you are trying to accomplish the same.  I believe there is also an option to post it to some web page for you to (securely??) check later.  The software emails me a message anytime my IP address changes.  Something like:

ipcheck.py: myserver.homeip.net good 69.92.107.193 -update successful

The script has a fairly exhaustive list of routers that it can poll the info from.

I use the option to check a really minimal url of http://checkip.dyndns.org:8245/ to display a super simple (well, it could be a little simpler) IP address.

If nothing else, the python script might help you with stripping out IP addresses of the above url.

Hope this helps.

Tim

There are several websites that will "reflect" your IP address
(whatsmyip.org, whatismyipaddress.com, auditmypc.com/whats-my-ip.asp,
showipaddress.com, and even things like secure order pages,
etc). You can even get this info from some MediaWikis if you're not
logged in:

http://en.wikipedia.org/w/query.php?what=userinfo&format=txt

However, all these pages return lots of extra junk, not to mention
HTTP headers, etc. Is there a "minimal" IP address reflector where I
could maybe telnet to a port on a given host and see my IP? Something
like the daytime service [port 13] NIST offers for the current time
(or time [port 37] service for binary data):

> telnet time-a.nist.gov daytime
Trying 129.6.15.28...
Connected to time-a.nist.gov.
Escape character is '^]'.

54309 07-07-28 16:59:56 50 0 0 523.2 UTC(NIST) *
Connection closed by foreign host.

only for IP addresses? I realize I could write one myself, but am
looking for an existing service.
