Okay, so you want to run wifi, well think green wifi. A network mesh of linksys wireless boxes, powered by solar panels, what do you get, a green network mesh than can be deployed over a city, mountain side or jungle (my selecta).

No Tagi’ve come across a number of good training vid on youtube, after ploughing through some of their cringe-o-matic promotional stuff, these are in the cbt nuggets/train signal mould, check the widget bottom left for more..
No Tagokay, so using an expensive lab is great, but what can you do if you’re at home. Emulation is the key.
Emulation is used for everything these days, from emulating old games machines, http://www.mame.net/download.html
or entire operating systems, http://www.cl.cam.ac.uk/research/srg/netos/xen/
to, of course Cisco routers!!!
Dynamips on windows!
you can now emulate cisco routers on your own pc, the http://www.ipflow.utc.fr/index.php/Cisco_7200_Simulator
is the thing.
Right.. follow this guide and you’ll have a nice new shiny cisco (virtual) router up and running in now time at all.
get this http://www.ipflow.utc.fr/dynamips/dynamips-0.2.7-cygwin.zipyou’ll need http://www.winpcap.org/ , which is needed for dynamips to communicat on the LAN!
okay, install all these bits and then open up a command prompt to the directory you’ve install dynamips in.
I did have to copy the cygwin1.dll from the cygwin directory, to the dynamips directory, if you do get an error on start, then try this!
J:\dynamips>dynamips-w2000.exe

Please specify an IOS image filename
Usage: dynamips-w2000 [options] <ios_image>
if you see this you’ve successfully installed it, I’ll cover using it more detail in later posts
your going to need a valid ios image, so you going to need to get hold of one, once you got your image
No Tagthe key to semester two is to know the command line, so get packet tracer installed, the latest version supports ospf, which reminds me, big stuff for you sem 3 lot is VLSM and all it’s accompanying friends, like supernetting, route aggregation and the like, if you aint on top of your subnetting then you really need to master it once and for all..
the clinchers for sem 4 are the NAT & DHCP, not forgetting Frame Relay & the dreaded ISDN, a service so old and so complicated it should be taken out and shot, really
i’ve stuck some download stuff in a widget down on the right, subnet & acl books to begin with, more to come cisco kids..

ethernet was developed as a mechanism that allows more than one computer to share the same piece of wire for communications purposes, read the original paper here, we will discuss this paper next week so please attempt to give it a look
semester twos haven’t really got started yet, the best thing you can do is to check out the product here and then play with the CLI mode in packet tracer, check here for a guide to getting started, ask me for a copy of the command line fundamentals handbook..
jp, know thyself and be true.. innit, this is the best simple overview of ospf there is, and it keeps coming back later in the curriculum, it’s also the most popular interior protocol because it’s cross vendor, EIGRP will only run on cisco kit.. you can get them to talk to each other though, which is possibly the key to completing the OSPF & EIGRP chapters side by side, i shall find an appropriate lab!
