PortPeeker

port listener with logging

Our Rating: (Good!)

PortPeeker is a standalone port listener, that uses whatever TCP/UDP port you specify and logs all incoming requests in detail. It provides a simple text log overview of all connections that have taken place, as well as their details. In addition, a handy drop-down box on top lists all the IP addresses that have connected, and selecting on will let you jump to the associate log entries. Useful for application testing (errors can be logged as well) and security monitoring for vulnerable ports. No install neeeded, just run the EXE file.
