A basic implementation of traceroute.
traceroute host -- print the route ip packets take to `host`
Trace the route to `host` by sending ip packets with short ttl
and using ICMP error advice messages to gain information about
intermediaries.
traceroute should be portable, but it's only tested on Mac OS X 10.11.6 and Ubuntu 16.04.04.
Create binary
$ make
If your operating system supports capabilites, grant traceroute the abilty to open raw sockets. Otherwise, run with sudo.
$ ./bin/traceroute example.com
If you wan to run the tests
$ make test
- Group responses by IP when printing
- Command-line parsing for basic options
- Support IPv6
- Support ICMP and TCP probes
- Support advanced options
- Test tools so network is not required
