mtr

MTR

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

**Note: This tool maybe called with sudo or as root, because it requires raw sockets.**

## Output

*Currently there is no support for non ipv4 targets*
