5 1 0:List of Ports Used by SEP sesam

Overview

SEP sesam client-server communication requires certain TCP ports to be open to enable SEP sesam components to communicate with each other through a firewall. Daemons are specific to the SEP sesam Client/SEP sesam Server/RDS installation and are using different port numbers.

The required ports may be SEP sesam version-specific. As of version ≥ 4.4.3 Beefalo, SEP sesam uses fewer ports by default than in previous versions:

• Default ports used for backup
• A complete list of ports used by SEP sesam

Ensure that all required ports are available on the system for SEP sesam daemons and are not blocked by a firewall; these ports must not be assigned to another service. If the required ports are not available, SEP sesam will not function correctly.

Additionally, you might need to open relevant network ports to ensure communication between SEP sesam Server or SEP sesam data mover and additional modules, e.g., VMware vSphere, NDMP, etc. A list of module-related ports can be found below in the section Module-related ports.

Used default ports

If a firewall is used, only the following TCP ports must be allowed for SEP sesam backup. SEP recommends SMSSH for secure control communication between SEP sesam Server and SEP sesam Clients/RDS and the HTTP protocol for data transfer from SEP sesam Client to SEP sesam device server. SMSSH and HTTP are the default protocols if no other protocol is specified in the client configuration and in the various events (backup/restore/migration etc.).

Component/Description	Direction	Source port	Destination port	Protocol	Configuration in the GUI
SEP sesam Server
SMSSH: Encrypted communication to the client	outbound	random	11322	TCP/SSH	Client properties -> Access Mode -> select SMSSH
Backup data over HTTP	inbound	random	11000	TCP/HTTP	Client properties -> Interfaces -> enter <http://hostname:11000>
SEP sesam Client
SMSSH: Encrypted communication to the client	inbound	random	11322	TCP/SSH	Client properties -> Access Mode -> select SMSSH
Backup data over HTTP	outbound	random	11000	TCP/HTTP	Client properties -> Interfaces -> enter <http://hostname:11000>
SEP sesam Remote Device Server
SMSSH: Encrypted communication to the client	inbound	random	11322	TCP/SSH	Client properties -> Access Mode -> select SMSSH
Backup data over HTTP	inbound	random	11000	TCP/HTTP	Client properties -> Interfaces -> enter <http://hostname:11000>

SEP sesam complete ports list

The following is the complete list of ports used by SEP sesam. You only need to open the ports in your firewall that you use. If you decide to configure all control communication via SMSSH, you do not need to open CTRL port 11301 in the firewall.

Port numbers for SEP sesam Server

Port number	Description	Configuration in the GUI/Example
11301	CTRL: Unencrypted communication to client	Client properties -> Access Mode -> select CTRL
11322	SMSSH: Encrypted communication to the client	Client properties -> Access Mode -> select SMSSH
11001	Data over FTP	Client properties -> Interfaces -> enter <hostname> or <ftp://<hostname>:11001>
11000	Data over HTTP	Client properties -> Interfaces -> enter <http://hostname:11000>
11443	Data over HTTPS	Client properties -> Interfaces -> enter <https://hostname:11443>
11002-11007	Port range for 3 parallel data transfers via FTP	Client properties -> Options tab -> Firewall Settings -> enter the port range in the STPD options
11701+drive number	Replication and source-side deduplication (SDS) port	For example: If you replicate from dedup drive 2 (source) to RDS drive 5 (target), the port is 11703 (daemon on machine with drive 2). If you replicate from dedup drive 5 (source) to RDS drive 2 (target), the port is 11706 (daemon on machine with drive 5).
11401	GUI/WEB UI (RMI) listen port

	Note
	For external backups (BSR, SAP, Informix, MaxDB ...) the client must always be able to reach the SEP sesam Server via ports 11000 (for HTTP backups), 11443 (for HTTPS backups) and 11001 (for FTP backups), and not only the RDS. This must be taken into account in the firewall rules.
