(DP) Support Tip: Linux security software preventing connections on port 5555

SELinux (RedHat) or APParmor (SUSE) are enabled by default and prevent connections to port 5555 on DP clients.

Appropriate rules should be created on both security tools to allow access to incoming/outgoing connections for DP.

But if you don't know ho to create such rules you can simply disable them by following these instructions:
