This is where it gets fun. In this part, we’ll set our wireless interface to monitor mode, and we’ll start sniffing some packets and dumping the captures into a file for further analysis. To start, we have to list the available wireless interfaces to the system. Hopefully your card is compatible and has a driver already loaded. Let’s fire up Konsole (a terminal application), which is the third icon from the bottom-left, and we’ll type: ...
It’s been long known that WEP is a very insecure wireless encryption protocol, and this is due to weak Initialization Vectors (IV) being used within. See, the engineers that designed the WEP protocol attempted to create a stronger encryption by adding a 24 bit IV to the cypher key that changes constantly, thus “eliminates” the repeated encryption of data with the same key over an over. The problem is, these IV’s are too short, and are periodically reused… which means that if we can sniff enough data over the air, and get the AP to reuse IV’s eventually, we can figure out the key. ...
So, since I recently wiped my ESXi box and installed CentOS 5.3 on it instead, I went with Zimbra for my e-mail solution, with LDAP authentication, and I have to say so far it works amazing… but e-mail push is a feature i’ll be missing on my phone… I found the solution to be something called Funambol. It is similar to what BES is for Exchange or Notes. It provides a sync interface for end devices into Zimbra, or Exchange, or others. I’ve been spending the weekend configuring Funambol and Zimbra to see each other, and my phone to sync with it. ...
