IPv6 Information
EndRun Technologies understands that IPv6 is still in the experimental stage with essentially no
mainstream deployment. Customers who are not interested in IPv6 need not burden your system with
it. You have a choice of an IPv4-only kernel (recommended) or the IPv4/IPv6-kernel. You may freely
change this at any time with an easy software download from our website.
To determine which kernel resides in your Tempus LX check the firmware version using the front-
panel keypad/display. Or you can use the console port command
cat /proc/version
.
An IPv4-only kernel will have a part number and version similar to:
6010-0041-000 ver 2.4.26-1
An IPv4/IPv6 kernel will have a part number and version similar to:
6010-0041-100 ver 2.4.31-IPv6
If you want to change your kernel please refer to
Appendix B - Upgrading The Firmware
for instruc-
tions. The following text refers to products with the IPv4/IPv6 kernel.
Enabling New IPv6
Capabilities
The presence of an IPv6-capable kernel will automatically enable most of the new IPv6 capabilities.
By default, autoconfiguration of the ethernet interface via IPv6 Router Advertisements is enabled. To
disable acceptance of Router Advertisements, or to configure a static IPv6 address and default IPv6
gateway, you must either run the interactive
netconfig
script or use the front-panel keypad/display.
Either method will allow you to configure your ethernet interface for both IPv4 and IPv6 operation.
Using the
netconfig
script has the advantage that you can also configure the hostname and domain-
name for the unit, and any nameservers you may want it to have access to.
OpenSSH
By default,
sshd
is factory-configured to listen on both IPv4 and IPv6 addresses. It may be forced to
listen on either IPv4 only, or IPv6 only by editing the /etc/rc.d/rc.inet2 startup script, where
sshd
is
started, and then copying it to
/boot/etc/rc.d
.
Net-SNMP
By default,
snmpd
is factory configured to listen on both IPv4 and IPv6 addresses. This may be
changed by editing /etc/rc.d/rc.local and modifying the agent address argument passed to
snmpd
at
start-up, and then copying it to
/boot/etc/rc.d
.
