Ports default state

[sky59]

I use Ubuntu 16.04LTS and need to know what ports are open/closed after fresh install.

I know port 22 is open because we can SSH pc with ubuntu. What about ports 443, 1193 and so on?

Thanx

Try:

netstat -atun

Port 22 should not be open unless you installed ssh-server.
For better control over ports, use ufw or gufw.
