The 2.60 RFS now contains the Net-SNMP open source implementation, which replaces the older
UCD-SNMP implementation, which did not support IPv6. There are several new directives in the
/etc/snmpd.conf related to IPv6. If you are upgrading and you need IPv6 capability with SNMP, you
should merge any changes that you may have made to the previous
snmpd.conf
file (which would be
stored in /boot/etc/snmpd.conf ) into the new snmpd.conf file, like trapsink addresses and community
strings. Using the new
snmpd.conf
, you can set up any IPv6 trapsink addresses. If you are using
snmpv3 secure access, you will need to perform the
createUser
operations to the new /boot/net-
snmp/snmpd.conf persistent configuration file. The older
/boot/ucd-snmp
directory is no longer used
for this.
New IPv6-Capable
syslog-ng
To enable remote syslogging to an IPv6 host, you will need to edit the new
/etc/syslog-ng.conf
file
and copy it to /boot/etc . At boot time, the presence of both the
syslog-ng
daemon and the boot/
etc/syslog-ng.conf
file will cause the new IPv6-capable
syslog-ng
daemon to be started instead of
the previous
syslogd/klogd
pair of daemons. These two files remain on the system for backward
compatibility with customers’ existing
/etc/syslog.conf
setups, but they are not IPv6 capable. If you
are not currently directing your system logs to a remote host, or you are not using IPv6, then there is
little or need or benefit to changing to
syslog-ng
.
Remaining IPv4-Only
Protocols
There remain several protocols in the 2.60 RFS which are not IPv6 capable:
telnet
(client and
server),
ftp
and
dhcpcd
. Due to their intrinsic insecurity,
telnet
and
ftp
are rapidly being dep-
recated, and probably have little business running over an IPv6 network. The address autoconfigura-
tion capabilities of IPv6 make the DHCP protocol less important, however it is likely that the new
dhcpv6
capability will appear in a future upgrade.
