Problem installing Litecoin Listening Full Node

So latest version of Litecoin Core Full Node is running, but it is not listening.


The problem is: My node is invisible from outside on TCP port 9333:


root@thc-1:~# nmap 140.82.58.152
Starting Nmap 7.01 at 2018-07-27 23:43 UTC
Nmap scan report for 140.82.58.152.vultr.com (140.82.58.152)

--- (same test but locally; TCP port 9333 is indeed closed.)

Basically TCP port 9333 isn't open... why ? (140.82.58.152 = host Bitcoin-1)
[/size][size=78%](+same problem exists with my other host 193.29.187.116 = host thc-1)[/size]
[/size][size=78%]Another question: Should I install Electrum-LTC server, or Electrum-LTC users just connect to plain Litecoin Full Node at random ?[/size]

Okay, problem SOLVED !


It turns out that 'nmap' doesn't scan a port of 9333 by default. So I forced a full port scan.



root@Bitcoin-1:~# nmap localhost -p 1-65535
