A MTR implementation written in golang, completely without shell-execs.
Just install with the following command:
go get -u github.com/tonobo/mtr
sudo setcap cap_net_raw+ep PATH-TO-GOMTR
or a precompiled version
curl -sL git.io/mtr.sh | sh -s -- -b /usr/local/bin && sudo setcap cap_net_raw+ep /usr/local/bin/mtr
Note: This tool maybe called with sudo or as root, because it requires raw sockets.
Currently there is no support for non ipv4 targets
