TCP Port Scanner/Query v1.0

I wrote this tool up for the technicians that I work with, they needed a quick way to perform port testing and using command line tools was too “advanced” :-p

Usage is very simple, put in hostname/ip and port number and hit go

TCP port scanner


  • TCP port scanning
  • Threaded to prevent application freezing during blocking calls


  • Finish code for UDP port scanning, this will be done by starting a listener on local machine and wait for response from remote endpoint. UDP is a stateless protocol which makes it a little bit trickier to detect when a port is actually in a open state
  • Add the following protocols
    • ICMP
    • GRE
