Network Security Monitor Daemon 4.0

The Network Security Monitor Daemon is a lightweight network security monitor for TCP/IP LANs. It will capture certain network events and record them in a relational database. The recorded data is available for analysis through a CGI-based interface.
You can run test version with ./Monitord, just to see how it works. Production version should be run in background, v.g. with nohup ./monitord &. Both versions will accept a device name as a parameter (default: eth0). You can send them SIGHUP at any time to print some stats. If you send SIGTERM, SIGQUIT or SIGINT, all threads will end gracefully.
Enhancements:
- Linux Kernel with "packet sockets" and "socket filtering" support.
- GNU C Library 2 (glibc2) with LinuxThreads support. (integrated in most recent versions).
- Full MySQL, including headers and libmysqlclient_r.
- GNU C Compiler (gcc).
- GNU Make (make).
- Perl (perl).
- Wget (wget).
Enhancements:
- Added chmod 4755 ... in Makefile
- Root should run make now, but not the daemon ;-)
- The daemon will drop root privileges as soon as possible
- (after creating the raw socket with an attached linux socket
- filter and putting the interface in promiscuous mode)
- No threads run with root privileges so its much safer
- (specially the new server thread which reads remote user input)
- Added stats thread
- To calculate/mantain exponential averages
- Added server thread
- It accepts HTTP requests and serves stats in XML
