6.5 Updating the DCM

Over the Internet

The easiest way to ensure that your DCM has all the latest software packages is to update it over the Internet.

The DCM is provided with a simple command-line script, upgrade, which checks for new versions of all packages in the distribution on the Gü ralp Systems Web site and installs them as necessary. It also rebuilds the configuration database to work with the new packages, resets it, and reboots the machine.

Running upgrade will restore the DCM to its factory settings, so make sure you will still be able to communicate with it before you issue the command, either

•

•

over a serial link to the DATA OUT port (115200 baud, 8 data bits, no parity bit, 1 stop bit, no flow control), or

over a DHCP-enabled network (using an IP address provided by the DHCP server.)

From the hard disk

If your DCM does not have access to the Internet, you can update its software from a connected USB disk. You will need to make a copy of all the files in the directory http://www.guralp.net/cmgdcm/feeds, including all subdirectories, in a directory called /cmgdcm/feeds on the hard disk. On Linux, you can do this with the command

wget -np -nH -m http://www.guralp.net/cmgdcm/feeds

Once the files are on the hard disk, you can install it in a DCM and transfer the packages with the command

upgrade gfat32

This facility is available with versions 2.10 and greater of the upgrade package.

The DCM as shipped includes a package gsl-backdoorwhich enables Gü ralp Systems to respond to support issues by remote administration (e.g. installing updated firmware or packages.) If you prefer not to allow Gü ralp Systems access to the DCM you should use the command
