No prob'
To remote access my clients machines, who are mostly cable/adsl connected, thus have dynamic IP, i need to know their IP. To do this, I have on my web site a small php script that logs the incoming request's IP in a table this way :
http://mysite.com/iplog/iplog.php/?ident=client1 -> [20070906 08:17] client1 xxx.xxx.xxx.xxx
When needed, I used to ask to my clients to call this URL (saved as bookmark) and picked the IP from the table.
I though I could give better service and do some night maintenance if I could know the IP without their help ...
You can complete by yourself
For my "other world"'s client (linux and Mac), i have the very convenient "curl" command witch can be shell scripted and croned easily, but as my Win world's knowledge are ... lacked, I needed help !
Thanks a lot !
