apaszke / tcp-ping Goto Github PK

Hello,

I have been trying to return the data. It works totally fine when I do console.log....but then I need to use the data for something else.
Please find the code.
Thanks.

pingTest(){ let msg= 'false'; tcpp.probe('www.google.com', 80, function(err, available) { return console.log(available); //msg=available; }); return msg; }

I see msg contains only 'false'.

Ping err argument always undefined regardless address valid or not.

Example:

const tcpp = require('tcp-ping');

// Ping VALID address
tcpp.ping({ address: 'google.com', timeout: 1000, attempts: 1 }, (err, data) => {
    console.log(err); // log `undefined`
});

// Ping INVALID address
tcpp.ping({ address: 'node', timeout: 1000, attempts: 1 }, (err, data) => {
    console.log(err); // log `undefined`
});

Specific option to only use IPV6 servers

I want to log my WAN availability, so i ping Google and my homepage to test if i can connect to them. Surprisingly probe is always returning true even tough i can not connect to anything at all.

I am not sure if i can just use avg and test for NaN to tell if i have no connection as that is the only clue i get when using ping of whether or not the connection failed. I assume so but i wanted to be sure so i ask here, maybe it would be a good idea to hint at this in the ReadMe.

Shouldn't this return false pretty much immediately? The timeout is 1ms. Instead it's waiting 21 seconds before returning false.

const tcp = require("tcp-ping");

let opts = {
    address: "good address",
    port: bad port,
    timeout: 1
}

tcp.ping({ address: opts.address, port: opts.port, attempts: 1, timeout: opts.timeout }, function(err, data) {
    let available = data.min !== undefined;
    console.log(available);
});

is this the expected behavior?

I wrapped the ping function inside a promise as below.

const tcpping = opt => new Promise((resolve, reject) => tcpp.ping(opt, (err, data) => err ? reject(err) : resolve(data)));

Perhaps native support for promises could be added.

no matter what i try to do i am getting undefined response time.

    tcp.ping({address:'google.com',attempts:5, timeout:150}, function(err, data){
      console.log(data);
    });

results: [{seq:0, time: undefined, err: {Object},

Hi! I was wondering if there are any docker images available with the tcp-ping package installed?
