Guralp Systems CMG-DCM - Manual (Page 9)

Operator's guide
•
Both mgetty and mgetty-r can recognize incoming PPP
connections and will automatically run a PPP daemon if you
attempt to connect to the DCM in this way.
•
Specialist services cnsn_in, cnsn_out and dss_sum are also
provided.
Network services
Because the DCM is a fully-fledged Linux machine, you will need to
set up networking before you can use it. Advanced networking is
beyond the scope of this manual. For a basic setup, you will need to
perform the following actions:
1. Assign the DCM an IP address. By default, the DCM will try and
use DHCP (Dynamic Host Configuration Protocol) to find its
own IP address. However, this requires a DHCP server on your
network. If you do not have a DHCP server, you will have to set
the IP address yourself.
2. Find out the IP address the DCM is using (if you have not set it
yourself).
3. If necessary, configure your own computer's IP address so that it
can communicate with the DCM.
See Section 2.4, page 15, for full details.
Once you have connected the DCM to your local network or to the
Internet, you can use a wide range of methods to retrieve data from it.
•
All DCM units feature an on-board Web server, which allows
you to monitor and configure the station from any browser (and
download data by HTTP, if enabled.)
•
For maintenance, you can log in to the operating system directly
over the secure shell protocol, SSH, and use all the standard
Unix/Linux tools.
•
A GCF server can be set up to transmit data to any application
that supports the GCF format (such as Scream!, Antelope, or
Earthworm.)
•
The DCM can act as a CD1.0 or CD1.1 transmitter to a specified
client, or to multiple clients as an option.
•
Optionally, the DCM can also receive and process AutoDRM
