In my previous article I was building SIPcrack from source on the Ubuntu 10.04 platform. I ran into a few erros during the build. The first error is explained here but after that I ran into one more. Below I describe how to get past the pcap.h error. This fix should work on any version of ubuntu that is giving you a pcap.h missing error.
I was building a tool called Sipcrack today from source and ran into some problems. The platform I was using was ubuntu 10.04 LTS but if you are getting this error on any Ubuntu platform the solution is most likely going to be the same.
