Automatic Nameserver Configuration
The primary and secondary name server’s addresses can either be statically
configured as above, or learned dynamically over an interface. Name servers
can be learned via DHCP over an Ethernet interface or via IPCP over a PPP
interface. The interface is specified using the command:
ADD IP DNS [DOMAIN={ANY|domain-name}] INTERFACE=interface
If no nameservers have been manually configured, and nameserver
configuration is assigned to an interface by either PPP or DHCP, this
configuration will be automatically used for the default nameservers. Name
servers configured in this way are identified by an “*” in the “Domain” column
of the SHOW IP DNS output table. Automatically-configured nameservers can
be deleted or replaced, using the commands:
DELETE IP DNS
SET IP DNS
A deleted automatic configuration may subsequently reappear if the interface
concerned is reset.
Telnet Server Port Number
The listen port for the Telnet server is now configurable, so that it can be
changed from the default value 23.
The LISTENPORT parameter has been added to the SET TELNET command.
The syntax is:
SET TELNET [TERMTYPE=termstring] [INSERTNULL={ON|OFF}]
[LISTENPORT=port]
The LISTENPORT parameter sets the TCP port over which the Telnet server
listens for connections. If this parameter is not used, the default port number is
23.
If the TCP listen port is changed from the default of 23, care must be taken to
ensure that any firewall or IP filtering configurations are matched accordingly.
Triggers for Ethernet Interfaces
Support for Ethernet UP and DOWN triggers on Ethernet interfaces has been
added, as per existing triggers for other interface types. This limitation on the
CREATE TRIGGER and SET TRIGGER commands is removed.
CREATE TRIGGER=trigger-id INTERFACE=interface EVENT={UP|DOWN|
FAIL|ANY} [CIRCUIT=miox-circuit] [CP={APPLE|ATCP|BCP|CCP|
DCP|DNCP|IPCP|IPXCP|LCP}] [DLCI=dlci]] [AFTER=hh:mm]
[BEFORE=hh:mm] [{DATE=date|DAYS=day-list}] [NAME=name]
[REPEAT={YES|NO|ONCE|FOREVER|count}] [SCRIPT=filename...]
[STATE={ENABLED|DISABLED}] [TEST={YES|NO|ON|OFF|TRUE|
FALSE}]
