Popfinder software monitors network and records IP addresses of POP3 user logins.
The application offers several valid options, including "-i interface" for specifying which interface to listen to (e.g., eth0), "-l logfile" for running multiple instances of the app and using separate log files (default: /var/log/pop_usage.db), and "-p" for turning off promiscuous mode sniffing.
Additionally, the "-U username/UID" option allows users to run the app under a specific user ID for extra security, and the socket will be opened before setting the user ID. The "-C /path" option is also available for the paranoid penguins, allowing them to specify which chroot jail to use.
However, it's essential to note that the logfile is opened every 5 minutes, so users must specify a relative logfile path that makes sense within the jail. Overall, this software is a useful tool for monitoring POP3 usage and identifying users connected to specific IP addresses.
