10 Inet Configuration

10.1 Introduction

This section describes how the Erlang runtime system is configured for IP communication. It also explains how you can configure it for your needs by a configuration file. The information is primarily intended for users with special configuration needs or problems. There is normally no need for specific settings for Erlang to function properly on a correctly IP-configured platform.

When Erlang starts up it reads the Kernel variable inetrc, which, if defined, is to specify the location and name of a user configuration file. Example:

% erl -kernel inetrc '"./cfg_files/erl_inetrc"'

Notice that the use of an .inetrc file, which was supported in earlier Erlang/OTP versions, is now obsolete.

A second way to specify the configuration file is to set environment variable ERL_INETRC登录查看完整内容
