54. pfSense

Replaces Barricuda NG Firewall, Check Point Appliances

This m0n0wall fork is also based on BSD, but is designed for regular computers, not embedded hardware.

57. tcpdump/libpcap

Replaces: OmniPeek, CommView,

Tcpdump is a command line packet analyzer, and libpcap is a C/C++ library for network traffic capture. Working together, the two provide a good network monitoring solution, but, lacking a GUI, they are not particularly user-friendly. Operating System: Linux.
