A very interesting howto written by Dr.Small, which might come handy to a lot of people, or perhaps some time in future.
I run into all kinds of predicaments when operating from behind a router, and one of them is, to be able to record my External (or WAN) IP, while behind it.
I am going to explain to you, how I succeeded in doing it, so you may do the same, if you are in the same ditch, and are like me, and run a ssh server or so. When you leave the computer, and you havenâ€™t checked your WAN IP for days, (if you have a dynamic IP), it tends to change.
So first off, here is a list of things you will need for this project:
- Expect. A simple little application. Iâ€™ll explain how to get it, in a second.
- A external or secondary website, which you have FTP access to.
So, letâ€™s start off and get the necessary things we need, while we are at it.
