Ports for inbound traffic

The following are the ports that are used by the DD system for inbound traffic.

Table 1. Ports Used by DD System for Inbound Traffic
Port	Service	Note
TCP 21	FTP	Port is used for control only if FTP is enabled (run 'adminaccess show' on the DD system to determine if this is the case).
TCP 22	SSH	Port is used only if SSH is enabled (run 'adminaccess show' on the DD system to determine if this is the case).
TCP 23	Telnet	Port is used only if Telnet is enabled (run 'adminaccess show' on the DD system to determine if this is the case).
TCP 80	HTTP	Port is used only if HTTP is enabled (run 'adminaccess show' on the DD system to determine if this is the case).
TCP 111	DDBOOST/ NFS (portmapper)	Used to assign a random port for the mountd service used by NFS and DDBOOST. Mountd service port can be statically assigned.
UDP111	DDBOOST/ NFS (portmapper)	Used to assign a random port for the mountd service used by NFS and DDBOOST. Mountd service port can be statically assigned.
UDP 123	NTP	Port is used only if NTP is enabled on the DD system. Run ntp status to determine if this is the case.
UDP 137	CIFS (NetBIOS Name Service)	Port used by CIFS for NetBIOS name resolution.
UDP 138	CIFS (NetBIOS Datagram Service)	Port used by CIFS for NetBIOS Datagram Service.
TCP 139	CIFS (NetBIOS Session Service)	Port used by CIFS for session information.
UDP 161	SNMP (Query)	Port is used only if SNMP is enabled. Run 'snmp status' to determine if this is the case.
TCP 389	LDAP	LDAP server listens on this port for any LDAP client request. By Default it uses TCP.
TCP 443	HTTPS	Port is used only if HTTPS is enabled (run adminaccess show on the DD system to determine if this is the case).
TCP 445	CIFS (Microsoft-DS)	Main port used by CIFS for data transfer.
TCP 2049	DD Boost / NFS	Main port used by NFS. Can be modified via the 'nfs set server-port' command. Command requires SE mode.
TCP 2051	Replication / DD Boost / Optimized Duplication	Port is used only if replication is configured on the DD system. Run replication show config to determine if this is the case. This port can be modified via the replication modify command.
TCP 2052	NFS Mountd / DD BOOST / Optimized Duplication	Main port used by NFS MOUNTD
TCP 3009	SMS (System Management)	Port is used for managing a system remotely using Web Based GUI DD EM (DD Enterprise Manager). This port cannot be modified. This port is only used on DD systems running DDOS 4.7.x or later. This port will also need to be opened if you plan to configure replication from within the DD GUI interface, as the replication partner needs to be added to the DD Enterprise Manager.
TCP 5001	iPerf	Port is default used by iperf. To change the port, it requires -p option from se iperf or port option from the net iperf command. The remote side must listen on the new port.
TCP 5002	Congestion-checker	Port is default used by congestion-checker, when it runs iperf. To change the port the new port needs to be specified in the port option of the net congestion-check command. The remote side must also be listen on the new port. It is available only for DDOS 5.2 and above.
