In the past we have written a couple articles on using tshark to strip WPA capture files down to a specific ESSID or SSID but in some cases it can be more useful to strip the capture down by BSSID or MAC address of the WAP. Isolating packets by BSSID or WAP MAC address is useful in a scenario where a wireless deployment has numerous WAP’s and you have captured a specific SSID’s traffic from more than one WAP. Below is information on how to strip down a capture file based on BSSID and information on capture size before stripping the file down.
If you are not hip to pfSense I suggest you check it out. It is an open source firewall that is making waves in InfoSec. The pfSense guys have a great howto for configuring IPSec VPN on the pfSense firewall as well as making connections via a freeware Windows IPSec VPN client called Shrew Soft which can be read by clicking here. The only item lacking in the article is a recommendation for a Mac OSX client as well as configuration tips for a Mac OSX client which is the sole point of this article. Below is information about where to download a freeware Mac OSX IPSec VPN client and then the necessary configuration to make a connection to the suggested settings noted in the howto of the pfSense web site.
The ATrpms repository provides many bleeding edge software packages so if you have a development server where you install new apps this repo can be very useful. The instructions are not 100% clear about how to install this repository on CentOS Linux which would also be the same on RedHat Linux but not on Fedora Linux. Anyhow the example used on the ATrpms site relates to Fedora so the repo file needs to be modified to work on CentOS as noted below.
While running a configure script before compiling an application on CentOS Linux I received an error regarding libdaemon which caused the configure script to fail. Using YUM I was able to list the available packages that included libdaemon in the name, install one, and then move past that error in the configure script. Below I show how to list packages using YUM with libdaemon in the name and then show example output of installing libdaemon-devel which is the package needed by the configure script.
While running a configure script before compiling an application on CentOS Linux I received an error noting that libgdbm could not be found. Below I display the actual error output that interrupted the configure script, how the correct RPM package to resolve the error was located, and the output of installing the new package on CentOS Linux via YUM.
