Ping hosts using tcp syn packets

Project description

synping

CI Version Downloads Ruff LICENSE

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 example.org

Pinging example.org 4 times on port 80:

Reply from 93.184.215.14:80 time=126.17 ms
Reply from 93.184.215.14:80 time=126.54 ms
Reply from 93.184.215.14:80 time=129.27 ms
Reply from 93.184.215.14:80 time=133.44 ms
