I’m trying to run a function in one of my config files, in this case
dev.exs, which will return the IPv6 of one of my network interfaces. This is not working (highlighted yellow):
although I know the function does work.
I’ve also put the function into a module and placed the module in the config folder, and the lib folder, but they weren’t able to be found by
dev.exs either. So how and where do I define a function or module, so that it can be used in dev.exs?
Separately, is there an easier way to find the IPv6 of my “tun0” interface, than this module/function?
defmodule GetIp do def get_ygg_ip do :inet.getifaddrs() |> elem(1) |> Enum.filter(fn x -> elem(x, 0) == ~c"tun0" end) |> Enum.at(0) |> elem(1) |> Enum.at(1) |> elem(1) end end
if you want to test the function you will have to rename
~c"tun0" to something the exists on your computer when using
ifconfig (leftmost column ahead of the colons are the interface names)
