tcping2 version
docker container can be used to run tcping2 without installation. Per default it starts the echo server.
docker run -d --rm -p 8080:8080 tommi2day/tcping2
listening on [::]:8080, terminate with CTRL-C
...
echo -e "Hello\nQUIT\n"|nc localhost 8080
Hello
#-------------------------------------------------------------
docker run -it --rm tommi2day/tcping2 tcp google.com 80 --dnsIPv4Root permission is required when running ICMP ping or MTR, since it needs to open raw socket. You can either use sudo command, or set setuid bit for tcping2.
