Identifying Listening Ports and Interfaces
To identify ports and network interfaces your Samba Active Directory (AD) Domain Controller (DC) is listening on, run:
# netstat -tulpn | egrep "samba|smbd|nmbd|winbind" tcp 0 0 127.0.0.1:139 0.0.0.0:* LISTEN 43270/smbd tcp 0 0 10.99.0.1:139 0.0.0.0:* LISTEN 43270/smbd tcp 0 0 10.99.0.1:88 0.0.0.0:* LISTEN 43273/samba tcp 0 0 127.0.0.1:88 0.0.0.0:* LISTEN 43273/samba tcp 0 0 127.0.0.1:445 0.0.0.0:* LISTEN 43270/smbd tcp 0 0 10.99.0.1:445 0.0.0.0:* LISTEN 43270/smbd ...
The output displays that the services are listening on localhost (127.0.0.1) and the network interface with the IP address 10.99.0.1. On both interfaces, the ports 139/tcp, 88/tcp, and 445/tcp are opened. For further information on the output, see the netstat (8) manual page.
To bind Samba to specific interfaces, see Configure Samba to Bind to Specific Interfaces.
Samba AD DC Port Usage
| Service | Port | Protocol |
|---|---|---|
| DNS * | 53 | tcp/udp |
| Kerberos | 88 | tcp/udp |
| End Point Mapper (DCE/RPC Locator Service) | 135 | tcp |
| NetBIOS Name Service | 137 | udp |
| NetBIOS Datagram | 138 | udp |
| NetBIOS Session | 139 | tcp |
| LDAP | 389 | tcp/udp |
| SMB over TCP | 445 | tcp |
| Kerberos kpasswd | 464 | tcp/udp |
| LDAPS ** | 636 | tcp |
| Dynamic RPC Ports *** | 49152-65535 | tcp |
| Global Catalog | 3268 | tcp |
| Global Catalog SSL ** | 3269 | tcp |
* On Samba AD DCs running the Samba internal DNS server.
** If tls enabled = yes (default) is set in your smb.conf file.
*** The range matches the port range used by Windows Server 2008 and later. Samba versions before 4.7 used the TCP ports 1024 to 1300 instead. To manually set the port range in Samba 4.7 and later, set the rpc server port parameter in your smb.conf file. For details, see the parameter description in the smb.conf(5) man page.
Note that other Active Directory (AD) related services that are not provided by Samba, such as ntpd, can open ports on a Domain Controller (DC) as well.
