Tiny IP Poster

All,

I've been looking for a few hours now for a tiny footprint IP Poster and have come up with nothing. Here's the specs I'm looking for:

-Posts a dynamic IP address via email on system startup
-Single executable file that requires no installation
-EXE is accompanied by some kind of config file with settings such as where/how to email the dynamic IP

Because this is a single executable with no install, it can be dragged and dropped into the Startup folder, or added to run at startup via the system registry. Does anyone know of something like this? The closest I found was something called 'TacoPost', but it wants to publish an HTML page with the IP information instead of emailing it.

Thanks guys!

How about this simple shell script?

Code:

ip addr show eth0 | tr ' ' '\n' | grep -A 1 '^inet$' | sed -e '1d' -e 's|/.*$||' | mail -s 'dynamic ip' username@backbone.net

Hope this helps --Jonas

Sorry, I should be more clear about a couple things. The first is that I posted this in the Non-*nix Forums because I was looking for a Windows executable that runs on Win32-based systems. Secondly, this is designed to be remotely installed and report back to a central server (in the form of an email), I know very well how to find/report my own IP.

Reading your post more closely, you sorta' hint at you wanting something for win32 systems. In that case, I've got nay idea. First you say you want it to send an email, now you say you want it to "report back to a central server". You may want to clarify exactly what it is you want.

My second idea for a solution would be to pipe the output of ipconfig (I think) through sed into an mta, but that requires you to install sed and an MTA.

If you know a netmask that matches exactly the dynamic IPs you're interested in, you could also set up a daemon on the central server which listens for TCP connections, sends a random challenge and, if the client reports back with a "proper" answer, reports the address of the client to you. That requires you to keep a private key private on the client machine, though (either by trusting all their users, or by doing the windows equivalent of `chmod go-r privkey').

Should be fairly easy to implement with a decent crypto library.
