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.
