simple server-side connection logger, useful as a simple honeypot
See start.sh for a simple startup script (e.g. this is what I use for my RDP honeypot), but basically:
$ connlogger -port N -logfile /path/to/logfile
Logs are line delineated, timestamp in format YYYY/MM/DD HH:MM:SS and then a report where the connection came from, including client IP and source port. Example:
2019/01/06 14:33:32 Connection received from: 115.236.70.116:53951
