Interviews With Everyday People Using Open-Source

Since opening Reverse Polarity, LLC, we have helped numerous everyday people experience and use Linux and many other open-source software products. We will be featuring a new series of interviews to tell the stories of those who have made the move towards Linux.

To kick off this series, we will feature the Founder, Member and CTO of Reverse Polarity, LLC, William "Bill" Arlofski. Take a look at the interview about his first experience with Linux, how he made the switch in 1997 and why he never looked back.

Getting Bacula's Bootstrap (.bsr) Files To A Safe Place Via Email

Here is a very simple script to make sure that your bootstrap files are emailed to an offsite system. This script may be called manually, or from a cron job, or from a Bacula Catalog backup job's "After" Runscript.

Reverse Polarity Sets Up A Tor Relay Node - Happy New Year Internet Privacy!

Because we believe that privacy and anononimity on the Internet are both very important, on January 1st, 2015 we set up a Tor Relay.

Tor stands for "The Onion Router".

If you are unfamiliar with Tor, please check out their website to learn more about who uses Tor and why it is so important now that many of the details of the NSA's illegal tracking and logging of all Internet communications have been revealed.

Not only are foreign communications being tracked and logged - ALL communications are. This means emails, web browsing, SMS text messages, instant messages, Skype and on and on, and it means all of your activity is being illegally tracked and logged.

As this new years begins we are making it a point to lend a hand to the Tor Project by running this anonymizing relay service.

Happy New Year Internet Privacy!


Monitoring Samba users, shares, and connections with Xymon

I thought it would be a good idea to monitor some basic stats from the Samba servers that we manage and maintain. It would be nice, for example, to know the total number of users in the domain (LDAP, or tbd), the total number of machines in the domain, the number of currently connected users, the number of currently opened shares, and total number of open files.

Of course, if we have all of this information, we are going to graph it too!

Below is a short Xymon external script (bash shell script) which gathers this information using pdbedit, smbldap-userlist, and smbstatus and reports the information back to the Xymon server.

Here is an example of a production Samba server's graphs from this test for several weeks:
