Some wget schtuff

wget -o /dev/null --post-data "var1=DFKSDFLSJFSLKJFS" http://www.YOURURL.com/file.php

Posting data to a webpage using wget! basically the --post-data is what makes it possible, and -o just suppresses output. fancy!

The magic command to make the -C option work in TCPDUMP

tcpdump -w capturefile -C 1 -tt -v -s 0 -W 3

-C is millions of bytes, so 1 is a single MB
-W is rotate 3 files and start overwriting the #1 file if you've reached the limit. This maxes out to 3MB of packets, and avoid memory problems. I will probably make this even less in time.

Some stuff that I can see when you connect to my open network, and you're not SSLed

I can infer :

your ip address
website urls/addresses your are checking out
your cookies
the time/date of your connection
type of requests
a bunch of stuff about the sites/ips you are accessing (server type, charset, encoding, expiry of cached items, etc.)
your type of computer
your browser

Managed to revive a bricked router recently
Managed to brick another router I had working fine yesterday...meh.

openWrt shows me many nice things...

Just like your average linux box...but you have about 1000K free to operate things (on a classic WRT54GL anyways). Choose your packages wisely!

And it also sports a nice GUI, so I can monitor you in pink colors

The end for now

Hardware harvesting

New router /w USB connector on its way...

Got my hands on TWO WRT54G's to do some flashing, testing and whatnot. I can actually try to create an AP with one and then attempt to connect using the other...hmm. Also got a 50m ethernet cable to get things going.

And then one of these two devices would be talking to my Arduino hypothetically through my Ethernet Shield mounted onto the arduino
