View Code? Open in Web Editor NEWA small desktop application that can be configured to listen for connections on various TCP/IP ports. It runs in the tray and displays/logs an alert when a connection is detected on any of the ports. I wrote it to detect scans that a group at my University were doing for security auditing purposes. It only detects actual complete connections to TCP ports -- so nmap's SYN stealth scans won't be detected. However, if an attacker/scanner is doing any kind of service detection or fingerprinting, they'll probably connect to the ports they're interested in. This program will detect those connections. A somewhat recent win32 build is available in the downloads section.
