[erlang-questions] Unable to access my inets http server from my phone or external PC

[austin aigbe]

Thanks Thomas.

Changing the bind_address to 0.0.0.0 solved the issue.

Surprisingly, the python server is also using 0.0.0.0 and I did not even
notice it.

C:\Users\eausaig>python -m SimpleHTTPServer
Serving HTTP on *0.0.0.0* port 8000 ...


Working version:

-module(web_server).
-export([start/0, stop/0]).

-define(PORT, 8000).
-define(SERVER_NAME, "server1").
-define(ROOT,"C:/Users/eausaig/Desktop/web_server").

start() ->
inets:start(),
{ok, _} = inets:start(httpd,
[{port, ?PORT},
 {server_name,?SERVER_NAME},
 {server_root,?ROOT},
 {document_root,?ROOT},
 {bind_address,{*0,0,0,0*}},
 {directory_index,["index.html"]},
 {server_tokens, full}]).

stop() ->
[{_,_},{_,P2}] = inets:services(),
ok = inets:stop(httpd, P2).

BR,
Austin



bind_address,{127,0,0,1} should be bind_address,{0,0,0,0}. 127.0.0.1 is the
loopback interface and only receives connections from the same host which
is why you can't connect from other devices.
