Lua socket problem

[Thijs Schreijer <thijs@...>]

This code;

 

local socket = require("socket")
local PORT = 30000

local server1, server2

print (socket._VERSION)
server1=socket.tcp()
assert(server1:setoption('reuseaddr', true))
assert(server1:bind("*", PORT))
assert(server1:listen())

server2=socket.tcp()
assert(server2:setoption('reuseaddr', true))
assert(server2:bind("*", PORT))
assert(server2:listen())

 

runs fine on Windows, yet on Linux (Debian 7, WM ware image) the second `bind` (for server2) fails with a "socket already in use" error. Despite the 'reuseaddr' socket option.

 

Anyone seen this and knows how to resolve it?

 

any help is appreciated.
