Ping hosts using tcp syn packets

Project description



Ping hosts using tcp syn packets.

Please note that full tcp handshake is used, we want the program to behave nicely and to explicit close the connection after each “ping”.

Simple example:

$ synping

Pinging 4 times on port 80:

Reply from time=7.40 ms
Reply from time=10.31 ms
Reply from time=7.18 ms
Reply from time=6.92 ms



Sent: 4 packets
Received: 4 packets
Lost: 0 packets (0.00%)

Min time: 6.92 ms
Max time: 10.31 ms
Average time: 7.95 ms


  • Works on Python 2 and Python 3

  • Uses only Python standard library for maximum compatibility


Install using pip:

pip install synping


Download and set executable permission on the script file:

chmod +x


Download and run using the python interpreter:
