typical line from the /etc/dss.cfg file might thus look like

HPAAZ0:VCXX:VC:BHN

The station name and location name must be equal to or less than 4 and 2 characters long respectively.

The seedname should be a three-character string specified according to the SEED channel naming conventions. In particular, seednames for vertical components should end in Z, those for N/S components in N, and those for E/W components in E.

The DCM's configuration database includes three further options relating to dssserver, which can be altered from the Configuration → Data Transfer

→DSS → Server page.

datatransfer.dss.server : Set this to on to run the server; off to disable it.

datatransfer.dss.server.port : The port number on which to listen for incoming DSS packets.

datatransfer.dss.server.password : The password all clients should use when registering with dssserver.

datatransfer.dss.server.options : Any additional options to send to the DSS server process (for advanced usage.)

Remember to click Save changes before you browse away from the page, if you want to keep the changes you have made.

Restarting the DSS server

To force the DSS server to restart, select Configuration → Data Transfer → DSS → Restart DSS Server, and click the Yes button. This action will immediately kill any running DSS servers, and currently-activated subscriptions

will be terminated without notice. Clients will have to register with the new instance of dssserver before they can continue receiving data.

SEED

The DCM can compile full SEED volumes in real time. To enable this, select yes for the disk.recordas.seed option under Configuration → Disk (see above.)

A configuration file, /etc/seed.cfg, is provided allowing you to provide technical information about the streams to be recorded in SEED format. The

DCM will only write SEED volumes for streams mentioned in this file. Clicking SEED configuration brings up a page in the work area which enables you to edit the file and its attributes directly.
