automatically email external IP

Really simply question: what is the easiest way to have my home linux
server email me its external IP whenever it changes / on an interval,
so I can connect to it remotely? (I have a Ubuntu file server at home,
which I want to connect to when I'm off at school: it's a dynamic IP of
course).

A web service that did this (kept track of the IP) would work as well.

I'm a relative Linux n00b (my other computer is a Mac , so I'd prefer
a program or service that did this, not to have to run some kind of
script but if that's what I have to do so be it...

I can't seem to turn up anything simple on Google.

Thanx in advance!

You don't need to have your ip mailed to you. What you want is called
"dynamic dns." http://www.no-ip.com provides a free service that works
on most major operating systems, including Linux.

It basically involves signing-up, and downloading the client for Linux.
You can set the interval that the client updates it's information, and
you're computer will always be available at the address you set up.

For example, you can create mycomputer.no-ip.net, and will be able to
use that hostname every time you want to connect to your computer,
rather than having to remember/lookup an ip.

Good luck!

I use dyndns.org for this. I run a script (ddclient) on our FreeBSD server
that checks IP and updates the dyndns.org record for the subdomain I
picked from them. The same script will run on Linux and can be downloaded
from dyndns.org IIRC. All I have to remember is 'ssh -p <nonstandardport>
<userid>@<mysubdomain>.homeunix.com' to get into my LAN remotely.

Obviously using the wrong search keywords.
