Ensure the Firewall Software Does Not Filter Out Required Ports

Some firewall software might filter out certain ports, which will prevent an SMB server from successfully joining a domain.

The following network protocols are used by the smbd service during a domain join operation, and must be available for the Oracle Solaris SMB service:

Domain Name Service (DNS)

53

Kerberos V Authentication

88

Kerberos V Change & Set Password (RPCSEC_GSS)

749

LDAP

389

NetBIOS Name Service

137

NetBIOS Datagram

138

SMB-over-NetBIOS

139

SMB-over-TCP

445

Note:

Ports 137, 138, and 139 are not required if NetBIOS services are disabled. See Disabling and Re-enabling NetBIOS.

Port assignment settings appear in the /etc/services file. For more information, see the services(5) man page.
