Another “at work” post!
I’ve been generating files which need to be distributed via a file server, but need to be encrypted using GPG (the open source PGP application). Rather than managing keys for a large number of users, instead, I have a text file with the user names in, and a batch file. Please see the below gist for details :)
At work we use Symantec Endpoint Protection, and in a lab, I was asked to confirm whether we could install it on our Ubuntu 14.04 servers. This took a few hops to get it installed, so I figured, I’d publish how I got it working, to save some other poor soul the trouble :)
Firstly, add the webupd8team’s Java PPA and update the repository cache: sudo add-apt-repository ppa:webupd8team/java && sudo apt-get update
This gives you the ability to install the Java 8 installer: sudo apt-get install oracle-java8-installer
This should download the install files, but for some reason, I was struggling to download it (the install script seems to struggle with downloading the actual .tar.gz file from Oracle), so I manually followed the link to http://download.oracle.com/otn-pub/java/jdk/8u77-b03/jdk-8u77-linux-x64.tar.gz, accepted the license, and placed the file in /var/cache/oracle-jdk8-installer/ and then re-ran the above apt-get install line.
— Note: This above issue was because I was running a caching proxy, which somehow doesn’t play nicely with this script. Turn off your proxy – should be all good :)
Next I had to install the Java Cryptography Extension which I got from the Java SE page. I placed this file in /tmp/jce_policy-8.zip (the filename is the one Oracle use) and replaced the files in /usr/lib/jvm/java-8-oracle/jre/lib/security with the ones from the extracted archive with this line: cp -b /tmp/UnlimitedJCEPolicyJDK8/*.jar /usr/lib/jvm/java-8-oracle/jre/lib/security.
The SEP client also has a dependency on the 32bit version of GLibc. I installed this with sudo apt-get install libc6-i386
I was then, finally, able to install the SEP client by unpacking the installer zip file, and running sudo bash install.sh -i from the path I’d unpacked the zip file in.
Not very complicated, I guess!

The company I work for have recently issued all On Call engineers in my team a Samsung Galaxy SIII Mini to give us access to company e-mail and resources out of hours. Rather than shipping a customized image, we have received a stock O2 imaged mobile, and so this is my limited guide to bringing this to as close to “Stock” Android as I can manage (or want).
Most of what we need is provided to us using a commercial solution called Touchdown, so I won’t be covering that here, as whatever you get shipped to you will not include that. I’ve elected not to use the device for my personal systems, barring my Google calendar, which means I’ll stand a fighting chance of not booking overtime and other work things for personal appointments.
So, on power-on, I completed the post-install steps, including setting up my Google account. I decided not to keep the device in sync with my Google account, as I already have a few other Android devices, and I don’t want to get my work infrastructure mixed up with my home kit.
Next, I went into Settings, and from there into the Google Account. I clicked on my e-mail address and unselected the following options:
After that, I went into Application Manager (again, in Settings), and swapped to the “All” tab. Firstly, I needed to clear out the downloaded contacts, which I did by selecting Contacts Storage, and then pressing the “Clear Data” button.
Next, I disabled all the applications that I either don’t need, or don’t want on my work phone. I did this by selecting each in turn, and then selecting the option to disable them. Here’s the list:
Wow, isn’t that a list!
My next step was to hide some of the applications I don’t need. To do this, I went into the applications page, pressed the menu button, and selected “Hide applications”. This puts selection boxes next to all the applications on the page, and once you’ve done selecting options, press “Done” in the top right corner to hide them. Here’s my list:
Lastly, installed a couple of applications from the Play Store:
Once I’d got Agenda Widget Plus, and Google Keyboard configured, I hid those applications in the applications pane too.
After all of that, I set up Touchdown… which you’ll need to follow up though your own instructions!
One final thing before I wrap this all up… even though I’m on-call, this doesn’t include being engaged via e-mail. As such, my e-mail doesn’t need to disturb me, and so I’ve disabled the touchdown application’s notifications for e-mail. To do this, go into Touchdown, make sure you’re at the “main” screen (not the default e-mail screen, but the one which also includes all your tasks and calendar options), and then press the menu button, press “Settings”, and select the “Advanced” tab. Scroll right to the bottom of the list, and press the “Email Alerts” button. Select “Customize settings” and then select appropriate options. If you leave nothing ticked, all you’ll get is a flag in the notifications tray showing an e-mail has appeared. Personally, I’ve turned on “Enable lights” and picked a colour, so I can quickly see whether I’ve had a mail just by checking the screen.
