:gen__icmp.ping crashes on CentOS 7
Closed this issue · 4 comments
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.
The actual error message is
{:undef, [{:pkt, :icmp, [{:icmp, 8, 0, 0, 43092, 0, {127, 0, 0, 1}, <<0, 0, 0, 0>>, 0, 0, 0, 0, 0}], []}, {:gen_icmp, :packet, 2, [file: '...gen_icmp/src/gen_icmp.erl', line: 355]}, {:gen_icmp, :"-ping/3-fun-3-", 6, [file: 'gen_icmp/src/gen_icmp.erl', line: 195]}]}
Looks like the pkt library can't be found. Check if it is being included in the release.
I added :pkt to extra_applications in mix.exs and looks like it is now included in the release (lib/pkt-0.4.4/)
I'm getting an error much sooner my release is crashing at the very beginning with this error:
