Description
The GNU/Linux operating system of the LANTIMEs SBC
(Single Board Computer) has been optimized to ensure
a high level of security and reliability.
Three LEDs (green/red) indicate the status of the
three main components: Reference Time (GPS), Time
Synchronization Service (NTP) and Network (Link
status). A fourth red LED is labeled ALARM and can be
configured to signal any event that is covered by the
notification handling routines.
The configuration of the system can be done by
using a standard web browser for accessing the
extensive but straightforward html interface.
Alternatively a text based and menu driven setup
utility can be started from the shell prompt after
logging into the unit via Telnet or SSH. Initial
configuration can be performed using the RS232
console port and a terminal program.
The security-related features of LANTIME time
servers satisfy highest demands. The time
synchronization data can be reliably signed and
secured by symmetric keys (MD5) and the NTP autokey
procedures. This protects the clients against
manipulated time and man-in-the-middle attacks and
allows them to verify that the NTP packets they
received were send by the LANTIME. Additionally the
whole LANTIME configuration can be done by using
encrypted channels (e.g. SSH, HTTPS or SNMPv3). Every
unused/unneeded protocol can be disabled in order to
reduce possible points of attack.
In order to support network management systems the
LANTIME time servers offer an extensive SNMP
interface, which can be accessed by SNMP V1, V2.c and
V3. It allows the monitoring of all relevant system
parameters (including operating system parameters,
network interface statistics, detailed GPS and NTP
status information as well as the complete system
configuration) and can be used to alter the LANTIME
configuration via SNMP set commands, too.
LANTIME time servers are designed to be deployed
in IPv6 networks, the NTP time synchronization as
well as the configuration interfaces (Web-based, SSH
and SNMP) comes with IPv6 support. You can assign
several IPv6 addresses and the system supports
automatic configuration by IPv6 autoconf.
The LANTIME M100/GPS is equipped with a high
precision "TCXO" oscillator (please check our
oscillator options
page for technical specifications). The oscillator
determines the holdover characteristics (e.g. when
the GPS signal is disturbed or jammed).
