I'm using :gen_icmp.ping in an Elixir project.

The code works fine when I run it via mix on my laptop, but when I make a release with distillery and run the same code on CentOS7, the line:

:gen_icmp.ping(addr)

crashes the process without any message.

I'm building the release inside a docker centos7 container. But later trying to run it on a physical CentOS 7 server.

Hi, Any idea how I could return something like :

$ ping friendpaste.com
PING friendpaste.com (94.23.221.113): 56 data bytes
64 bytes from 94.23.221.113: icmp_seq=0 ttl=54 time=36.183 ms
64 bytes from 94.23.221.113: icmp_seq=1 ttl=54 time=321.526 ms

ie, how can I get the ttl ? and packet size (for the last one I guess the payload lenght is OK) .

Hi,

This is not an issue but a feature inquiry (unless it already exists and I've missed it).

I need to send packets (mainly for ping and traceroute) through different interfaces and I couldn't find the way do do it. On the command line with the linux ping, you can set the option -I <interface> or -I <address> and the packets are sent through the interface with the proper source address regardless of the routing table.

1. Is there a way to do this
2. Is there a way to set the source address
3. If not, do you have plans to integrate it ?

Thanks for the great work anyway : this lib is very useful.
Cheers

Hello,

I'm using gen_icmp in an Elixir project. The compilation fails on macOS.

I've cloned to test it, and sure enough when I run rebar3 compile it fails with the following error:

Since in Elixir land one can override dependencies, I've managed to get it to compile inside my project by using the latest version of procket with {:procket, git: "https://github.com/msantos/procket", override: true}, but it would be nice if gen_icmp could compile without additional workarounds.

Cheers!

Maybe should you replace it with os:timestamp?

I always get big negative values for Elapsed. Is this fine? How can I make use of it? (like converting it to ms as in ping):

Hello!

I have no idea if this problem is related to this project at all but the error mentions it so I figured I'd start here. I'm running an elixir app via releases and I'm seeing some issues with another library I wrote that uses gen_icmp - error I'm seeing is:

{:error, {:undef, [{:procket, :socket, [:inet, :raw, :icmp], []}, {:gen_icmp, :init, 1, [file: '/app/deps/gen_icmp/src/gen_icmp.erl', line: 233]}, {:gen_server, :init_it, 2, [file: 'gen_server.erl', line: 374]}, {:gen_server, :init_it, 6, [file: 'gen_server.erl', line: 342]}, {:proc_lib, :init_p_do_apply, 3, [file: 'proc_lib.erl', line: 249]}]}}

I wrote a very thin wrapper around this that I'm currently using: https://github.com/silverp1/elixir-ping

Just wondering if anything in the error happens to jump out at you, I'm a bit stumped. Thank you!

Hi, when I track an IP address, I get the below answer : [timeout,timeout,timeout,timeout,timeout,timeout,timeout,
timeout,timeout,timeout,timeout,timeout,timeout,timeout,
timeout,timeout,timeout,timeout,timeout,timeout,timeout,
timeout,timeout,timeout,timeout,timeout,timeout,timeout,
timeout|...]
how i'can fix it ?
thank.

Do you still plan to add ipv6 support ?

Hi

Currently building procket is broken on at least OS X, this is resolved in the procket master branch.

Procket has not been released with the new rebar3 commit which solves the OS X building.

Would it be possible to either push a new version of procket or to switch to procket master?

Also, to send ICMP on OS X, i need to start the Erlang VM with root privileges, is there a workaround for this?

heya,
i'm trying to use this to send ipv6 icmp ping requests using

gen_icmp:ping("dns.google", [inet6])

this works perfectly fine on linux, but errors with enoprotoopt on mac -- both machines are in the same network and have a valid IPv6 address assigned to them

what would be the steps to get this working on macos, or what information would you need to figure out why it's not working?

I'm having this error when my laptop doesn't resolve a domain name.

State: :ok

My own code looks like

result = :gen_icmp.ping(item.host, [List.to_atom(item.inet)])

So I don't think it could be an error from my side (although I may be wrong).

Needless to mention that a standard command line ping works perfectly fine. I am getting timeout in 100% calls. I am not an Erlang expert but wrote few things. I would appreciate any help with debugging this as I do not even know at this stage what might have gone wrong. This is not the only module that involves cross-compilation but this is the only one that works-otherwise. First of all I checked the procket's cross-compile's CFLAGS and LDFLAGS and I haven't noticed anything apparent. Please see below excerpt.

This is probably something silly on my side and I hope to help improving the module's cross-compile build if this would appear to be the case.

Checked with the wireshark and no single ICMP packet is being spit out onto the wire.

Hello!

I'am newbie in erlang and elixir. i'am totally misunderstand why :gen_icmp.ping doesnt works in elixir.

elixir@elixir-VirtualBox:~$ uname -a
Linux elixir-VirtualBox 3.19.0-25-generic #26~14.04.1-Ubuntu SMP Fri Jul 24 21:16:20 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

I created test mix project, where i include gen_icmp as dependency

defmodule KV.Mixfile do
  use Mix.Project

  def project do
    [app: :kv,
     version: "0.0.1",
     elixir: "~> 1.0",
     build_embedded: Mix.env == :prod,
     start_permanent: Mix.env == :prod,
     deps: deps]
  end

  # Configuration for the OTP application
  #
  # Type `mix help compile.app` for more information
  def application do
    [applications: [:logger, :gen_icmp]]
  end

  defp deps do
    [{:gen_icmp, git: "https://github.com/msantos/gen_icmp.git"}]
  end
end

then i ran (i'am trying with sudo and without)

sudo mix deps.get
sudo mix deps.compile
sudo mix compile

As i realize, all compiled successfully, because on erlang (but in another folder and with rebar), on same machine all works well.

After that i ran:

elixir@elixir-VirtualBox:~/elixir_test/kv$ iex -S mix
