10.4.2  Changing Ports

Table 10–1 describes the ports used by SEA and indicates whether or not they can be configured.

Table 10–1 Ports 
Port Number
Used For
Configurable
7901
Director-to-Director communications, and communicating with the Director on the local system through the CLI.
Yes
7902
Director's Web Interface listener port used by the web browser (e.g., http://target.sys.name.here:7902)
Yes
7903
Communication between SEA's applet (running inside the web browser) and the Director.
No
7920
The WEBES WCCProxy process communicates with the Director on this port.
No.
1998
Service Cockpit
No
2069/8941
CSG/QSAP—the port number for CSG v4.5 and v5.0 is 2069. For v3.1 and v3.1B it is 8941. (See Section 11.4.2 for more details on CSG/QSAP.)
Yes
25
SMTP mail. This is the standard port used by TCP/IP systems for SMTP (see Section 11.3 for more details on configuring SMTP).
No

If a port is configurable, you can change the port number used. Most ports are configured using the web interface; however, the commSocketListenerPort, which is used for connections to the Director, can only be modified from the CLI.

Connections to the Director

The commSocketListenerPort defines the TCP/IP socket port used by the Director to communicate with other processes on the same system or on other systems on the network (Port 7901, by default).

Note


Do not change the commSocketListenerPort attribute with the web interface. If you do, the Director cannot be stopped from that point on. After the socket port is changed, only a service that is already connected can stop the Director running on the old port.


To change the TCP/IP socket port attribute on all operating systems use the following command from the command prompt.

desta msg -chgport nnn
Where nnn is the new port number

This command changes the port number and then stops the Director and all connected processes. After the Director has finished shutting down, you can safely restart it on the new port.

Note


If the process hangs unexpectedly under Windows, kill the command and stop the Director manually. Press CTRL-C to exit the CLI command, and then enter net stop desta_service.


The Director can only communicate with Directors on other systems that have the same TCP/IP socket port number defined in their configuration. You can restrict access to your Director by changing the ports to nonstandard numbers and only disclosing the new port numbers to people who need access.
