CMG-DCM

The following sections describe how to operate a DCM from the Linux command line, including descriptions of all commands unique to the DCM. Any of these commands can be included in your own shell script files, which can be run as services on the DCM or remotely using a ssh connection as required. If you need to compile your own C or FORTRAN programs to be run on the DCM, please contact Gü ralp Systems for assistance.

6.3 Configuration

Configuring the DCM is automated by a suite of command line tools. These maintain a configuration database and check that all the relevant Linux files are kept up to date. If you alter the standard Linux configuration files, you should bear in mind that these tools will overwrite them without checking that they match the information in the database. Because of this you should use the tools wherever possible rather than editing the files directly. The DCM's Web-based configuration system is just a front-end to these tools.

gcfgdbls prefix : Enter this command to find out which configuration options begin with the prefix prefix (case sensitive—all the configuration options are in lower case). The options are listed in alphabetical order. For example:

~# gcfgdbls serial.0 serial.0.baudrate serial.0.handshaking serial.0.ppp serial.0.service

gcfgdbset option-namenew-value : Enter this command to set the value of the named option to new-value. The database will perform a simple type check on your value (for example, to check that certain options are numbers), but will not otherwise make sure that your change makes sense.

gcfgdbget option-name-or-prefix : Enter this command to find the current value of the named option. Instead of a single option name, you can also use a prefix (as described above) to find out the values of a range of options. The remaining tools also allow you to use prefixes in place of full option names.

Each option in the database can be marked either as “clean” or as “dirty”. This

flag tells the DCM whether the database is currently in sync with the state of the device. Whenever you alter the value of an option using the gcfgdbset tool, or using the Web interface, the option is marked as “dirty”; the DCM then alters

its configuration, and marks the option as “clean” again, to signify that the change completed successfully. Three more commands are provided to allow you to access this flag:

gcfgdbmark clean option-name-or-prefix : Enter this command to mark the named configuration option as “clean” in the database.
