the Zen of Communication.

So, just as an fyi, I’ve added some stuff on. Here’s a short list.

1) The posts now show who wrote them! That way I’m not getting all the credit for everybody else’s creativity – Bad Karma. However, given that it took me a week to find how to properly use the php show author tag, it will be a while before I make the author’s name a link to go to either a custom page, or a list of their other posts. But it will happen. That way someone can go “Who’s this guy? I’d like to see more of what they’ve written”.

2) Posts will automatically snip on the main page. It will link to “(::Read More… ::)” after the first paragraph. So write posts as lengthy as you want, and just include a paragraph break somewhere in there.

Very short list. But stuff none the less.

Found this file from a Chinese university. It’s the password recovery procedures for a Catalyst 2900XL. I’ve got a few more recovery guides I’ve dug up for some other routers, I’ll chuck those up in a bit.

While this is probably fairly common knowledge I thought I would round up the information and experience I had gathered and present it from the perspective of someone who is new to networking. While I’m sure this is also possible under Linux I’m not that experienced in that OS – maybe later.

Items:
Laptop or PC (should be located on the same network as device to be sniffed)
Software (my experience was positive using Wireshark, formerly Ethereal)
Administrative access to the Laptop or PC

Overview:
Installing Wireshark will provide you with the ability to do some basic sniffing of a remote Windows PC but unless that PC routes its network traffic directly thru Wireshark some traffic will go undetected. Initially I tried adding a secondary network adapter and physically running the remote device traffic thru the laptop using a network bridge. This worked for about 5 seconds and then the remote PC stopped working. After doing some more research I found a simpler method (other than just running Wireshark on the PC) was to enable my laptop to accept VPN connections. Then on the remote PC I set up a VPN connection to point to my laptop. I then started up the VPN on the remote PC to my laptop and the started up Wireshark on my laptop. This worked very well and allowed me to successfully see all traffic to and from the remote PC.

Details:
How to enable the acceptance of VPN traffic
