How should this be done if the computer is behind a router? In other words, it would be the router's IP that is actually changing, right? So can the computer behind the router detect that the router's IP changed?
No, the router's IP should not change, but you will have to go *outside* the router to get your changed IP, ie: curl www.whatismyip.com |grep Title|awk -F ':: ' '{print $1}' note: this is cludged together from previous examples provided here. I do not know awk to get *only* the IP, but this works on my box thru the router. -- Patrick Shanahan Registered Linux User #207535 http://wahoo.no-ip.org @ http://counter.li.org HOG # US1244711 Photo Album: http://wahoo.no-ip.org/gallery
