About half way through the day. Had a moment to to sit for lunch. Some highlights of the day.
-UBNT had some of the new Unifi 3 on display. Very heavy duty feeling unit. The new Nanobridge was on display. I am impressed with the design. Much easier to replace the things which go bad. The ethernet port no longer has the grommet.
-The lunch Keynote included the CEO of ARIN John Curran. Very good talk. Great amount of humor mixed with useful information.

Do you have a Ubiquiti radio you can SSH into but can’t do much else with? If you are needing to do a factory reset via terminal here is the command:
cp /etc/default.cfg /tmp/system.cfg
Thanks to SamT for the heads up.

For thos of you looking for some information on QOS for VOIP and such on Ubiquiti Airmax check out this wiki article
In order for AirMax to classify and differentiate types of traffic when applying QoS rules, the traffic must have a special value set in the IP Header DSCP field. The originating software or hardware device is responsible for applying this value, and only if this field is set will traffic be prioritized.
There are four traffic categories: Best Effort, Background, Video, and Voice, which range from priorities lowest to highest in that order.
By default, all traffic is classified as “Best Effort”, meaning there is no prioritization applied. The other categories can be defined with the following values:
|802.1p Class of Service
|0 – Best Effort
|1 – Background
|2 – Spare
|3 – Excellent Effort
|4 – Controlled Load
|5 – Video (<100ms latency)
|6 – Voice (<10ms latency)
|7 – Network Control

This is advance notice that there is a scheduled change to the IPv4
address for one of the authorities listed for the DNS root zone and
the .ARPA TLD. The change is to D.ROOT-SERVERS.NET, which is
administered by the University of Maryland.
The new IPv4 address for this authority is 188.8.131.52
The current IPv6 address for this authority is 2001:500:2d::d and it
will continue to remain unchanged.
This change is anticipated to be implemented in the root zone on 3
January 2013, however the new address is currently operational. It
will replace the previous IP address of 184.108.40.206 (also once known
We encourage operators of DNS infrastructure to update any references
to the old IP address, and replace it with the new address. In
particular, many DNS resolvers have a DNS root “hints” file. This
should be updated with the new IP address.
New hints files will be available at the following URLs once the
change has been formally executed:
The old address will continue to work for at least six months after
the transition, but will ultimately be retired from service.

There has been a run of IPV6 questions to myself and on some of the mailing lists. I figured I would do a short list of some best practices for those of you who have a basic understanding of IPV6.
-Use /48 for customer allocations. Give each customer a /48 unless they can show greater justification.
-Use /64 or /126 or /127 for P2P links
-Use /128 for loopbacks. Assign the same loopbacks out of the same /64. You won’t run out of looback addresses.

So I finally decided to upgrade my home router to ROS 6.0. With RC5 just coming out I figured it was a good time to do so. Some notes
I upgraded a RB450G. Board firmware went from 2.41 to 3.02. Dear mikrotik a changelog on this would be nice.
The terminal screen has some basic commands to help you get starte if you are new to command line.
The Plus is now blue. Much more soothing.
