Question

PHP

I thought in unix time 10 numbers. And there is also this: 1488796017149.
What is this?

Answer 1

First, not numbers, but numbers. Second - it's just milliseconds instead of seconds, so 13

Answer 2

An extremely difficult question - https://en.wikipedia.org/wiki/Unix_time

Answer 3

There is also such a good thing as ufw (ubuntu firewall), the port is enabled with it like this:
ufw allow 32348

Answer 4

Well, have you launched the masternode?
From the fact that the port is open, no one will listen to it and it will not ping from outside. nobody listens to him.

Answer 5

iptables -I INPUT -p tcp --dport 32348 -j ACCEPT
