Adventures with spammers

I run a Zimbra mail server at the K-12 school district where I work. Overall I really like the system, but my user base is very susceptible to phishing spam so once a month or so someone will give up their password to a spammer who then proceeds to use our mail server to send…

My impressions of LISA’13

For me there were two primary take aways from LISA’13. The first is that because of the “internet of things”, the fact that we carry phones with us everywhere, and that data collection and storage costs become much smaller than the costs to sort through data to determine what data to keep; we have ubiquitous…

Ski’s 2013 Candidate Statement

I feel that LOPSA is poised for a time of growth.  We are getting more interest from system admins, from companies who cannot find system admins to hire, and from students who are starting to realize that system administration is a good career.  I have been focused on improving LOPSA's communications with it members and prospective members by putting out the LOPSAgram on a monthly basis, posting to social media sites about LOPSA events, representing LOPSA at several conferences such as SCALE, LinuxfestNW, LISA, and ACPENW via working the booth and giving talks, mentoring several people at work and via the mentorship program along with co-chairing the Cascadia 2012 IT Conference.  I have also been involved in setting up a new 4 year system admin degree at Bellevue College in Bellevue, WA.

How to redirect a single computer to a different IP using BIND

So a major webfilter vendor has a huge bug where they do not filter https connections that include an '&' in the URL. For a school district this is a very bad thing because we are not filtering any connections to google sites (e.g. images and videos are the big ones). The solution is to set up BIND to only redirect www.google.com to nosslsearch.google.com. This forces the connection to a non-https connection so the webfilter will work correctly. Continue reading

MacOS using AD logins and duplicate names

I work for a K-12 school district that uses Macs as the primary client machines. Currently our students log into the Macs with a generic account and use their AD account to attach to the file server. We are migrating our Mac laptops and desktops to use AD domain logins so the students can start logging in to the Macs with their AD account. One of our wonderful students decided to log in with their full name instead of their user id (student id) and it worked. Please note that you cannot login with the full name on a Windows machine joined to the domain so this is a Mac strangeness thing.

VMware upgrade process ordering problem

I needed to upgrade our 3 copies of VMware Workstation for work today. I purchase these using a corporate credit card that is managed by our administrative assistant and is in her name. In the past this has never been a problem but today… I log on to the site, go to the store, select…
