DNS configuration

This section reports the current status of the DCM's domain name resolution

service. This is done by presenting the contents of the standard Linux /etc/resolv.conf file.

#eth0 begin domain guralp.local nameserver 192.168.0.1 nameserver 192.168.0.2

#eth0 end

For further information, see the Linux manual page for resolv.conf.

Data Out Port, Serial Port A, Serial Port B

The next three sections report information about the DCM's serial interfaces. A typical reading for one port might be:

/dev/ttySA0, 115200 baud, none handshaking, service getty 0 GCF blocks received on this port

In this example, /dev/ttySA0 represents the device name of this serial port in the Linux filesystem. The remaining information on this line reflects the current setup of the port, based on your choices on the Serial port configuration page. See Section 4.3, “Serial port configuration” for more details.

115200 baud : The speed of data exchange over this link, as set up by the serial.x.baudrate option.

none handshaking : The flow-control protocol used over this link, as set up by the serial.x.handshaking option.

service getty : The service provided over this link, as set up by the serial.x.service option.

The second line reports how many valid blocks of GCF (Gü ralp Compressed Format) data have been received over this link since the last reset or change in data port configuration. If the link is being used for a service other than GCF data transfer, this number may be disregarded.
