On a fresh server with nothing installed, port 22 is the only thing that is open on my machine. (Or at least amongst common ports)
After installing Virtualmin only, number of ports were opened, like 80 and 443.
lsof -i :19132 suggests that the server is listening to port 19132
Despite doing all above, online port check tools suggest that port 19132 is closed.
What am I missing? What do I have to do in order to open a port?
Also, as I mentioned on the things I’ve noticed, Virtualmin was able to open ports on its own during installation. How can it do that?
Could be that Hetzner are blocking the port in the data centre. I know I’ve had to ask data centres to open non-standard (or at least lesser used) ports before.
