Between the two commands there's a lot of duplicate functionality, but there's also a lot of necessary divergence. Unifying these commands (and allowing user selection for IPv4 or IPv6 functionality) would mean only requiring one utility." My read from this is: 1. Create a new "traceroute" tool 2. based on the existing traceroute/traceroute6 code 2. in C 3. Accepts either an IPv4 _OR_ and IPv6 address 4. Works correctly for whatever the valid input is 5. unifies the two separate commands currently 6. Intelligently re-use shared code Unit test cases: traceroute 8.8.8.8 traceroute 2607:f8b0:4004:815::200e Beckman On Sun, 23 Feb 2020, Takumi Kataoka wrote: > Hi , > My name is Takumi and senior college student in Japan. > I'm thinking to participate Google Summer of Code 2020. > And I'd like to work on FreeBSD. > > I found "Dual-stack traceroute(1) command" in GSoC ideas list , it's > sound interesting for me. > Could you tell me more details about it? > > Sincerely, > Takumi Kataoka > _______________________________________________ > freebsd-hackers@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-hackers > To unsubscribe, send any mail to "freebsd-hackers-unsubscribe@freebsd.org" > --------------------------------------------------------------------------- Peter Beckman Internet Guy beckman@angryox.com http://www.angryox.com/ ---------------------------------------------------------------------------
