The situation: I was running two wireless webcams (Airlink101 AIC 250W) in order to monitor my laboratory. Both of these were connected to a linksys router. Only port 22 and 80 were opened by the university. We were forwarding port 80 to a Debian box running apache.
The goal: We wanted to have a page, e.g.www.externalhostname.com/image.html, serve up images from both the webcams. Using apache.
The solution:
A friend came up with this neat solution.
The following is assumed:
First the html file -- image.html:
Finally, copy the following from /etc/apache2/mods-available to /etc/apache2/mods-enabled:
proxy.conf
That's it.
The goal: We wanted to have a page, e.g.www.externalhostname.com/image.html, serve up images from both the webcams. Using apache.
The solution:
A friend came up with this neat solution.
The following is assumed:
- The external dns name is www.externalhostname.com
- The cameras have the LAN ips 192.168.1.121 and 192.168.1.122
First the html file -- image.html:
<html>
<head>
<title>Lab Webcams</title>
<META HTTP-EQUIV="REFRESH" CONTENT="5">
</head>
<body bgcolor="rgb(0,0,122)" text="white">
<table border="1">
<tr>
<td>

<tr>

<img src="http://www.externalhostname.com/cam1/image.jpg" width="320" height="240"/>
</td>
<td>
<img src="http://www.externalhostname.com/cam2/image.jpg" width="320" height="240"/>
</td>
</table>
</body>
</htm>
Next, configure apache using /etc/apache2/httpd.conf:
LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy.so
LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so
LoadModule proxy_connect_module /usr/lib/apache2/modules/mod_proxy_connect.so
ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass /cam1 http://192.168.1.121
ProxyPassReverse /cam1 http://192.168.1.121
ProxyPass /cam2 http://192.168.1.122
ProxyPassReverse /cam2 http://192.168.1.122
Finally, copy the following from /etc/apache2/mods-available to /etc/apache2/mods-enabled:
proxy.conf
<IfModule mod_proxy.c>proxy_http.load
</IfModule>
# Depends: proxy
LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so
proxy.load
LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy.so
That's it.
