netconfig
This command starts an interactive script that allows you to configure the IP network subsystem of
Meridian II. By default, the unit is configured to configure itself using the Dynamic Host Configura-
tion Protocol (DHCP). If you need to set up static IP configuration, you must run this script as
root
from the RS-232 serial I/O port during the installation process. Refer to Chapter 2 - Basic Installa-
tion, Using netconfig to Set Up Your IP
for details on the use of the command.
This script creates or modifies these files:
/etc/HOSTNAME
,
/etc/hosts
,
/etc/networks, /etc/resolv.conf
and /etc/rc.d/rc.inet1.conf . All of these are non-volatilely stored in the FLASH disk /boot/etc direc-
tory. You must reboot Meridian II after running this script for the changes to take effect.
Command:
netconfig
MeridianII reply: Interactive script is started.
ntpconfig
This command starts an interactive script that allows you to configure the NTP Subsystem of Merid-
ian II. By default, the unit is configured to authenticate its replies to clients using its default MD5
keys in the /etc/ntp.keys file. If you need to create your own MD5 keys (recommended) or set up
broadcast/multicast operation, you must run this script as root. Refer to
Chapter 7 - Configuring the
NTP Server for details on the use of this command.
The two files that are modified are /etc/ntp.keys and /etc/ntp.conf . Both of these are non-volatilely
stored in the FLASH disk
/boot/etc
directory. You must reboot Meridian II after running this script
for the changes to take effect.
Command:
ntpconfig
MeridianII reply: Interactive script is started.
ntpstat
This command provides some key information regarding the operation of the NTP daemon. It shows
the current offset between the NTP-steered system clock and the GPS Subsystem, the counts of re-
ceived, sent and dropped packets, and the sent packet rate. The format of the response is:
YYYYMMDD.HH:MM:SS +S.sssssssss RCVDCNT SENTCNT SENT/sec DROPCNT
Where:
YYYY is the year of the UTC timestamp of the most recent update received from the GPS Sub
system.
MMDD is the month and day-of-month of the UTC timestamp of the most recent update received
from the GPS Subsystem.
