Insights179 Comments

I finally got an iPhone 4 and decided to create some custom ringtones to try out on it. The first one that I created, using the method we documented in this previous article, is the sound of a dial-up modem connection. After creating the ringtone by converting an MP3 file to an m4a and then renaming then m4a to m4r I attempted to sync the iPhone to iTunes to copy over the new custom ringtone however it was not available in the Ringtone Sounds configuration section on the iPhone 4. After troubleshooting I finally figured out a solution which is documented below.

SecurityLeave a comment

Pyrit was recently upgraded on a server that I use and when I logged in to run it manually from the CLI I noticed an error. The error, which is explained in more detail below, complains that the libpcap is to old. The server that this pyrit installation is installed on is CentOS 5.4. CentOS 5.X only provides libpcap version 0.9.4-14 as the latest available libpcap version in the yum repositories. At first I searched for a newer libpcap in third party repos though I was unsuccessful so I upgraded libpcap using the source. Below is more information regarding the error and how it was resolved.
