EX403 - Satellite Ports

[Ger_]

Hello there,

I'm currently preparing for EX403 and was wondering, if there is a way of displaying all needed opened ports by Satellite/Capsule Server. Would be a nice shortcut if i would not have to remember that 12 Ports, but just a short command or man Page for that topic.

The "RH-Satellite-6" firewalld service config seems not to do the job as there are some Ports missing.

Picture from RH403 Lab environment (v6.11, Provisioning Ports missing eg. 53,67)

Thanks in advance

A trick is to check all listening ports with ss or netstat, both for TCP and UDP connections, eg:

ss -tuln | grep -v 127.0.0.1

That will give you a list of all the ports that expect to receive connections from the external world.
