Failed to torify node application

Question

I'm writing a simple node server, and trying to torify it. But I got the following error, any idea?

It works fine when I go without torsocks, and I used default config for tor daemon.

$ torsocks node server.js
[Jan 26 09:38:40] WARNING torsocks[30933]: [syscall] Unsupported syscall number 293. Denying the call (in tsocks_syscall() at syscall.c:465)

var http = require('http')

// Create server
var server = http.createServer(function (req, res) {
    console.log("client connected")
    res.end('HI!')
})

// Listen
server.listen(process.env.PORT || 5000)

I got it. I checked the torsocks debug message, I see the following.

[listen] Non localhost inbound connection are not allowed. (in tsocks_listen() at listen.c:64)

And I changed my code to listen on localhost only, problem resolved.
