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.

$ firewall-cmd --add-service=RH-Satellite-6-capsule --permanent

Worked for me

Hi @Ger_ 

Observe in your images the line: "includes: foreman".

This is an inclusion of others services, so in this case, you need check this service, and possible others that will be included.
