If you use Ubuntu on the ORACLE cloud, special extra steps are needed.

This is what worked for me, based on this thread: [ubuntu 18.04 - "No route to host" when trying to connect to a TCP service on an Oracle Cloud Intance - Super User](https://superuser.com/questions/1487012/no-route-to-host-when-trying-to-connect-to-a-tcp-service-on-an-oracle-cloud-in)

**The following extra steps were needed on the Oracle cloud, to open up ports on Ubuntu 20** :

1. `sudo vim /etc/iptables/rules.v4` (or whatever editor you use)
2. After the line `-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT` , insert:

`-A INPUT -p tcp -m state --state NEW -m tcp --dport 1234 -j ACCEPT`

**(change the number of the port that needs to be opened!)**

1. At the shell prompt:

`sudo su -`

`iptables-restore < /etc/iptables/rules.v4`

`exit`

1. The newly-opened port may be tested by going on _another_ Linux machine, and issuing the command:

`nc -zvw100 THE_IP_ADDRESS_OF_MACHINE_WHOSE_PORT_WE_OPENED THE_PORT_NUMBER`
