Snort is a libpcap-based packet sniffer/logger which can be used as a
lightweight network intrusion detection system. It features rules-based
logging and can perform content searching/matching in addition to
detecting a variety of other attacks and probes, such as buffer
overflows, stealth port scans, CGI attacks, SMB probes, and much more.
Snort has a real-time alerting capability, with alerts being sent to
syslog, a separate "alert" file, or even to a Windows computer via Samba.
