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.
