lua socket client

I am trying to make a simple lua socket client for the Socket Server example, from the Lua Socket page.

The server part works though, I tried it with telnet.

But the client part isn't working.

local host, port = "127.0.0.1", 100
local socket = require("socket")
local tcp = assert(socket.tcp())

tcp:connect(host, port);
tcp:send("hello world");

It is only supposed to connect to it, send some data and receive some in return.

Can someone help me fix it?

Your server is likely receiving per line. As noted in the receive docs, this is the default receiving pattern. Try adding a newline to your client message. This completes the receive on the server:

local host, port = "127.0.0.1", 100
local socket = require("socket")
local tcp = assert(socket.tcp())

tcp:connect(host, port);
--note the newline below
tcp:send("hello world\n");

while true do
    local s, status, partial = tcp:receive()
    print(s or partial)
    if status == "closed" then break end
end
tcp:close()
