    Please could someone please list the default TCP/UDP incoming/outgoing ports and the services that use those ports on a freshly installed Cpanel/WHM? Many thanks.

    Many thanks for your answers. Exactly what I was looking for.

    Appropriately embarrassed seeing the FAQ for the question I asked :eek:. I will cross-reference those two sources and post a follow up here for future reference to compensate.

    Thanks again for your time and help.

    As promised

    Below are the default ports, protocols, and the direction they are open on a WHM/CPanel installation. This is on a fresh installation of WHM/CPanel hosted on CentOS VPS with my hosting provider. Yours may differ depending on OS, hosting company, hosting package, WHM/CPanel version, installed programs, services running ect. Any corrections, additions are most welcome.

    Something like 20 TCP/UDP I/O-I/O means: Port 20 should be open both in inward and outward directions for both protocols TCP and UDP.
    Code:
    [SIZE="2"][b]PORT	PROTOCOL	OPEN	SERVICE	NOTES[/b]

    993	TCP	I	IMAP4 	Incoming email SSL
    995	TCP	I	POP3	Incoming email SSL
    2077	TCP	I	WebDAV	Distributed authoring
    2078	TCP	I	WebDAV	Distributed authoring SSL

    2086	TCP	I	WHM	WHM control panel

    You can you use search port by range or number tool it contain data from different libraries.
    When i'm searching some permanently free port for my service, i use this tool.
