Table 5.9 – continued from previous page
Parameter Description
DHCP Timeout Time within a DHCP server is expected to respond to the
LARA DHCP client request. If there is no response, the
last known IP settings will be used to configure LARA.
IP address IP address in the usual dot notation.
Subnet mask The net mask of the local network.
Gateway IP address In case the LARA should be accessible from networks other
than the local one, this IP address must be set to the local
network router’s IP address.
Primary DNS Server IP ad-
dress IP address of the primary Domain Name Server in dot nota-
tion. This option may be left empty, however LARA won’t
be able to perform name resolution.
Secondary DNS Server IP ad-
dress IP address of the secondary Domain Name Server in dot
notation. It will be used in case the Primary DNS Server
can’t be contacted.
Primary Time Server IP address of the primary NTP (Network Time Protocol)
compliant timeserver in dot notation. LARA will synchro-
nize its own absolute time with the timeserver’s one. This is
important for writing log entries and for the Dynamic DNS
Service.
Secondary Time Server IP address of the secondary NTP compliant timeserver in
dot notation. It will be used in case the Primary Time
Server can’t be contacted.
Remote Console & HTTPS
port Port number at which LARA’s Remote Console server and
HTTPS server are listening. If left empty the default value
will be used.
HTTP port Port number at which LARA’s HTTP server is listening. If
left empty the default value will be used.
Telnet port Port number at which LARA’s Telnet server is listening. If
left empty the default value will be used.
Dynamic DNS
Peppercon provides a Dynamic DNS service that can be used in the following scenario (see Fig-
ure
5.22 on the next page):
LARA is reachable via the IP address of the DSL router, which is dynamically assigned by the
provider. Since the administrator doesn’t know the IP address assigned by the provider, LARA
connects to a special dynamic DNS server in regular intervals and registers its IP address there.
The administrator may contact this server as well and pick up the same IP address belonging to
his card.
The administrator has to register a LARA that is supposed to take part in the service with the
Dynamic DNS Server. He will get an approved nickname and password in return to the registration
process. This account information is needed in order to determine the IP address of the registered
LARA.
You have to perform the following steps in order to enable Dynamic DNS:
1. Make sure the LAN interface of LARA is properly configured.
