01. Election Results (Warner) 

I'm pleased to announce our new board members! Our independent monitor
Andrew Hume compiled the results of the election and the report.
Welcome our new and returning board members: 

William Bilancio
Paul English
Chris 'Ski' Kacoroski
Atom Powers 

The new board members will assume their positions at the next annual
in-person board meeting, which will be scheduled within the next few
This is also when the officers will be elected. Until then, Dan Rich and
Mark Honomichl will be serving the remainder of their terms. 

I want to thank our board members who are leaving for their time and
contribution to LOPSA. Dan Rich, our exiting President, has been a board
member since 2009. Mark Honomichl stepped up earlier this year after a
board member resigned. I also want to thank Nicholas Brenckle and other
candidates for running. 

The elections were conducted by the Leadership Committee. Without their
hard work, we would not have an election this year. Thank you Andrew Hume,
Lee Damon, Matt Okeson-Harlow, and Scott Murphy! 

Meanwhile, if anyone would like to nominate a candidate for the 2016
election or volunteer for LOPSA in any capacity, please contact the
Leadership Committee.

06. From the Mailing Lists
Tim Kirby started off a discussion on IT Roles within a company that 
touched on IT and how to relate to the business and executive mgmt
of the company. Some good ideas in this thread if you are trying to 
make IT more than just a cost center at your organization. There were
also good discussions on the professionalization of system admins
and the future of LOPSA. 

07. A Lesson Learned (Ski)
I recently moved from an 10 year old DNS/DHCP/IPAM roll my own setup to a
new integrated vendor supported product. The old system was a non-split 
master-slave setup for DNS while the new system was a split multi-master 
with views. We cut over the the internal DNS/DHCP with no problems, but 
when we tried to cut over the external DNS (different view) nothing
In the course of debugging the problem we went back and forth a few times
between the old and new setups and somehow our one of our old servers
ended up serving internal IPs to external users which took several of our 
external sites off the internet for 24 hours. 

What happened was that the multimaster setup was missing an ACL on the
external view that was blocking access from any IP to it. While we
were debugging this, we accidentally brought up the old external slave 
server before the old external master server. The external slave did a
query for its zones and because it was on the internal network, it got
the internal zones from the new system. It then proceeded to serve up
internal IPs to external users. 

Lessons Learned:
* As usual it is a chain of events that causes the problem. In this case
it was changing from non-split to split DNS where the servers are
operating under different assumptions, the ACL problem, not having a
good rollback process, and having all servers on the same network.
* Once you get bad DNS data on the internet, there is very little you can
do about it. OpenDNS and Google have ways to flush their server caches
but no one else did. Figure at least 24 hours for it to get corrected.
* Bad DNS data can seem to be random because people use pools of servers.
When I hit, I would get 25% correct data, 75% bad data. If folks
hit the servers from other parts of the country they would get almost 
all good data. It was totally dependent if a person had tried ot access
our external sites while we were serving up bad data.
* The above item makes testing very difficult. We initially tested with
two different ISPs and they worked ok as they had previously cached good
data. It was only a few hours later that people started complaining 
and I started testing other DNS servers and found the problem. 

08. Chapter News
On July 9th, Seattle LOPSA members will be hearing from Jason Gifford
of Fortinet on "Breaking the Kill Chain: Prevent, Detect, and Mitigate
Threats to your Organization". 

LOPSA Columbus met on June 25 and CJ Estel presented about the database 
change and tracking tool that he's about to open source. The presentation 
was titled Managing and Tracking Database Deployments. What's even cooler 
is that his presentation was a preview of the presentation that he's
giving at LISA later this year! 

Watch LOPSA Columbus for an announcement soon for the July event. LOPSA 
Columbus, DevOps Columbus, and the Central Ohio Linux User Group will be 
holding a joint social on July 31 for System Administrator's Appreciation Day at CoverMyMeds.
