IPv6 Information
The RTM3205 Precision Timing Module supports IPv6 out-of-the-box with a modern version 3.2.2
Linux kernel. During network configuration, you have the option to disable IPv6 on either or both
Ethernet ports. The IPv6 addressing scheme will see expanding deployment in the near future due to
the fact that there are no longer any IPV4 addresses to be allocated in many regions of the world.
IPv6
Capabilities
The presence of an IPv6-capable kernel will automatically enable most of the IPv6 capabilities. By
default, autoconfiguration of the Ethernet interfaces via IPv6 Router Advertisements is enabled. To
disable acceptance of Router Advertisements, or to configure a static IPv6 address and default IPv6
gateway, and to configure IPv6 domain name servers, you must run the interactive
netconfig
script.
This will allow you to configure your Ethernet interface for both IPv4 and IPv6 operation. You can
also configure the hostname and domainname for the unit.
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/ssh/sshd_config
file and modifying the
Ad-
dressFamily
directive, and then copying it to
/boot/etc/ssh
. Refer to the
sshd_config
man page for
detailed information (
man sshd_config
).
Apache HTTP
By default,
httpd
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/httpd/httpd.conf
configuration file and
adding a
Listen
directive, and then copying it to
/boot/etc/httpd
. Refer to the Apache HTTP docu-
mentation for details.
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.snmpd
and modifying the agent address argument passed to
snmpd
at
start-up, and then copying it to
/boot/etc/rc.d
.
