after reading several posts on GroupStudy about the point-and-click interface on the lab exam, I've start thinking on how to emulate it, or at least how to obtain something similar.
Basically I need a topology diagram with clickable routers, and a putty window that opens and connect to the clicked router... so what's better of the old HTML image maps?
I've tryed with this online tool: http://www.maschek.hu/imagemap/
using one of my lab diagrams (that one you will see in the next post...)
And this is the result:
Obviusly you may have clicked on routers on the image above... if you use M$ Internet Explorer, maybe the browser can't handle a link to that complex applications like telnet :-) (tested on my M$ IE 8.0 only)
But if you used firefox, other good reason to choose it, you have obtained a putty/other terminal emulation program, with an error like "can't connect to localhost:nnnn", if you have your rack ssh-tunneled listening on that ports, or a dynamips running... you where connected!
(if firefox says "cannot handle protocol", see http://kb.mozillazine.org/Register_protocol )
Let see step by step how to create it:
STEP 0: create your network diagram, with DIA, M$ Visio, GNS3 or take a screenshot of your favorite's vendor workbook, and save it in a jpg format (use GIMP to manipulate the image if needed)
STEP 1: go to the online tool page ( http://www.maschek.hu/imagemap/ ) and upload your topology image
The result will look like:
STEP 2: draw CIRCLE shape on routers (be patient on it) and add the target of the link. The trick here is that the link is pointing to "telnet://whateverIP:port", so your browser will start your default telnet application (or ask what it is). Point to putty when your browser asks the first time, flag all the "always do that action"/"don't bother me with that question again" :-)
Oh, by the way, here is the screenshot of the first circle on my diagram:
STEP 3: repeat step 2 for all the devices on your topology, then press the HTML button to view the html code:
STEP 4: copy the html code in a notepad, and add simple html to create a web page:
As you can see, the html code is really simple, just a few lines.
Then save as .html file (not .html.txt!) and open it with your browser (firefox again..).
It will be nice to do an html simulation with various diagrams (L2/L3, IGP, BGP, IPv6...) and the tasks in html too, but I never attemped a lab until now, so I don't know how it looks in the exam (and IF you can tell/reproduce the real graphical interface or it's under NDA).
well, hope this helps someone to feel confident with the point-and-click format of the exam.
Now it's better I go back to studying :-)
