SecurityLeave a comment

Ever located an old capture file and you weren’t sure what was in it or needed to grab some quick statistics about another capture file? What about needed to run statistics on multiple capture files and present them via a database or a spreadsheet? Well if you have ever run into any of these scenarios then capinfos is worth a look. The capinfos command is available via the Backtrack CLI and provides statistic information about cap files. This is one of the gems located on Backtrack that nobody ever hears about.

ipcalc – Backtrack 5 – Miscellaneous – Miscellaneous Network – ipcalc

SecurityLeave a comment

A tool that is more than likely not used very often in Backtrack is the ipcalc which is a command line to that will quickly provide you broadcast address, network address, netmask, and Cisco wildcard mask. If you do a lot of Backtrack Linux installations that each require different IP information for various networks this tool can be really useful to verify settings made in the networks file in Ubuntu/Backtrack. I used to find myself breaking out a iPhone IP calculator on a regular basis and while I still do use that application I prefer ipcalc from the command line if its readily available. Below are details regarding ipcalc and the various switches available to it.

Alex and I rewired our entire network the other day with cat 6 cable and new gigabit switches. Once we got it all set up we decided to do some testing. One of the tests we ran was transfer speeds from our file server to our laptops. We were trying to determine the network linkspeed when all of a sudden I realized that I had no idea how to do this on my mac. We decided to figure it out, and when we did, we of course wrote a article to help every one else. Below I will outline the simple steps to view your link speed in Mac OSX.
