ipfilter and ipv6

September 24, 2013 nlogician Leave a comment

For people running older versions of Solaris, like 8/9, the firewall of choice to install was `ipfilter`. Now, with Solaris 10 it has become the default, built-in with the OS. I wanted to do a short post about adding configuration settings for ipv6 and plan to cover ipv4 in detail in a later post.

One thing to note is that `ipfilter` must run it’s ipv6 rules under a separate file. In Solaris 10, the default location for the filter rules is in `/etc/ipf` and the firewall rules are located in the files `ipf.conf` and `ipf6.conf` for ipv4 and ipv6 respectfully. Here is a sample of the current file on one of my servers,


#
# ipf6.conf
#
# IPv6 Filter rules to be loaded during startup
#
# See ipf(4) manpage for more information on
# IP Filter rules syntax. Continue reading ipfilter and ipv6 →

Cisco archive command

The Cisco archive command has been around for several years now and is still valid for smaller operations that are unable to afford or require a commercial software package to do the same thing. Two of the main benefits include backing-up your configurations after changes and logging the commands that were executed by each user. The commands necessary to accomplish these tasks are fairly straightforward,


sw1# config t
sw1(config)# archive
sw1(config-archive)# path ftp://192.168.100.50/configs/sw1
sw1(config-archive)# write-memory
sw1(config-archive)# log config
sw1(config-archive-log-config)# logging enable Continue reading Cisco archive command →
