Use a hypertext link to call another program. In this example we call the telnet program. So let's telnet to microsoft

www.microsoft.com

The html code for the is:

<a href="telnet://www.microsoft.com:80">www.microsoft.com</a>

NB: The :80 redirects the request to tcp port 80

This can be great for creating active Network Diagrams use hotspots on the GIF to create telnet hyperlinks to the device, pick on the routers below to activate a telnet session. 

 

The html code for the hotspots:

<map name="hypertelnet">
<area href="telnet://10.0.0.1:80" shape="rect" coords="43, 13, 167, 62">
<area href="telnet://10.0.0.2:80" shape="rect" coords="29, 108, 165, 167">
</map>
<img border="0" src="images/network.gif" usemap="hypertelnet" width="200" height="200">

The code breaks out as follows:

map name # Define a map
area # define a area for the hotspot
 shape #  define shape type (rect, circle, polygon)
 coords # set co-ordinates
img # Pull in the image
 usemap # reference the map you created
