Finding your WAN IP address
My server sits behind a NAT router, so finding out my public IP address is a non-trivial task. I can use curl to poll checkip.dyndns.org for my current address:
The current IP check returns the information in this format: <html><head><title>Current IP Check</title></head><body>Current IP Address: 216.239.39.99</body></html>
Using cut, I can extract just the information that I need:
That produces something a bit more readable: 216.239.39.99

1 2 curl -s checkip.dyndns.org
The current IP check returns the information in this format: <html><head><title>Current IP Check</title></head><body>Current IP Address: 216.239.39.99</body></html>
Using cut, I can extract just the information that I need:
1 2 curl -s checkip.dyndns.org|cut -d ":" -f2|cut -d "<" -f1
That produces something a bit more readable: 216.239.39.99
