Trying to build simple app to notify about changes in small string... Help?
I'll give a simple explanation about my problem. I'm using ADSL as connection, and I use an external modem/router to connect. Thus, the router takes my WAN IP, and my PC gets a LAN IP which isn't of much use.
I can fetch the WAN IP manually by connecting to the router's internal HTTP server. Anyway, I've created a shell script that outputs the WAN IP into stdout in it's purest form (xxx.xxx.xxx.xxx).
Why did I do this to begin with? Well, simply put, my ISP shifts my IP every now and then, and I'd like to find out when. Thus, I'd like to build a simple application that would use extract the WAN IP every now and then, and notify me and/or log whenever changes occur.
I have close to no programming experience, so I'm basically asking if anyone here can help me out, or point me to some tutorial that I could find useful.
Thanks in advance,
