Try to find ping executable at runtime

[lotharsm]

Currently, the getStatus() function relies on the ping executable being located in /usr/bin/ping. Some systems (e.g. Gentoo) use other paths like /bin/ping which breaks this function.

By using which ping instead, we could try to find the executable at runtime instead of hardcoding the file location.

yep, good idea!

Thanks!

@Brueggus indeed, basically this just shifts the main problem.

@iandk I just tested it on Gentoo Linux, there it's enough to call ping directly without providing the absolute path to the executable...

What about setting /usr/bin/ping as the default and make the path to the ping command configurable somewhere?

I think I'd keep your solution, works on valet and the other environments I tested it on.
