Hello,

I'm trying to use a java program for my webcam page, but there is one slight problem. I'm on DSL and my IP changes, and the java needs the exact IP! I've been tryign to use a program called IP-Update for the pages I need updated, but the program doesn't work half the time, and was really poorly written to start with--sometimes it modifies the source files instead of the destination files, and things like that.

Someone said to use

Code: Select all: echo $SERVER_ADDR

or

Code: Select all:

, but that only returns my LAN IP

Does anyone know of either a program that can take source files and stuff my IP in them, or a way to get the server to include the WAN IP? Any hel pwould be greatly appreciated!

Thanks
John

[EDIT]
P.S. I can use a page like http://www.changeip.com/ip.asp to get my external IP...that is actually what IP-Update uses as well.

Yes I wrote the things about $SERVER_ADRESS and so on... and now I've got the same problem and I am searching for any hints resolving this.

Any Idea?

Okay, I don't know if this will work for everyone, but I've found a cheap way to get this to work. It uses PHP, and uses an address that the server doesn't know that still resolves to the server's IP. I use DynDNS, and my DNS is aries-iii.homeip.net, but it uses wildcards too so *.aries-iii.homeip.net will work as well. The server knows it is aries-iii.homeip.net but it doesn't know ip.aries-iii.homeip.net so this works

Code: Select all: IP.PHP <?php $IPaddy = gethostbyname("ip.aries-iii.homeip.net"); // gets IP $output = $IPaddy; $myfile = "e:\\wampp2\\htdocs\\protected\\ip.txt"; if($file=fopen($myfile, "w")) { fwrite($file, $output); } ?>

Code: Select all: CAMPOP.HTML <html> <head> <title>WebCam Popup</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head>  Page last updated  <body bgcolor="#000000" text="#00FF00" link="#0000FF" vlink="#FF00FF" alink="#00FFFF"> <p align="center"> <applet width="640" height="480" code="JavaCamPush.class" archive="JavaCamPush.jar" codebase="http://:8888/applet/"> <param name="cabbase" value="JavaCamPush.cab"> <param name="URL" value="http://:8888"> </applet><br> </p> </body> </html>

I'm pretty sure I could have just put the PHP into the page, but I wanted to be able to just use the trick in any page if I need to. Wish I coudl figure out a way to only call the php script if it is needed like when the IP changes.

I don't know, but you could try using this as a heading for HTML.
<meta http-equiv="expires" content="Thu, 5 Mar 2003 00:00:01 GMT">
<meta http-equiv="refresh" content="3600">
This says that the page has allready expired so it has to renew its content.
It also fixes an amount of time to wait to do the refreshing:
1 hour.
It depends on the proxy content. Some stuf, I saw with Netscape browser, are declared that don't need to renew. So the browser skips it and leave the old value. But when you close-stop your server, it changes instantly.
Better try what happens.
Hope it helps.
Thank's for your code
Alberto
