ping's interface option doesn't work on BSD

[Ulrar]

Hi,

The ping's interface option seems to use -I, which on linux is to set the interface but on BSD has to do with multicast. In any case, it doesn't work, so either a fix or a warning in the doc would be good.

Can you let me know a bit more about your platform and ping version (ping -V perhaps)?

The system is opnsense, which is based on freebsd. Ping doesn't have a -v, and as with most things on bsd, most of the options aren't the same as on Linux unfortunately Le 25 janv. 2018 23:43, "Daniel Nelson" <[email protected]> a écrit : Can you let me know a bit more about your platform and ping version (ping -V perhaps)? — You are receiving this because you authored the thread.

Thanks, I'll take a look.

FreeBSD ping doesn't have a parameter to specify the outgoing interface. But it has one to specify the source address. This has in most situations the same effect. To do it you have to use the parameter S. I'll make a pull request this evening (CET).

Well that's a lot harder to use if you're trying to monitor dhcp or ppp interfaces, since you don't know the IP you'll get, but if that's the only solution it's better than nothing :) 2018-01-26 6:38 GMT+00:00 Philipp Weber <[email protected]>:
