Ubuntu 15.04 — Utilities and Configuration

This is a continuation of my series of notes on my install of Ubuntu 15.04 on my laptop. The full list of posts is on this page. Previously, in the last post, I installed Ubuntu and restored the files.

Installing Ubuntu 15.04

Labor Day Weekend made for the perfect time to get my laptop updated.  I know Ubuntu 15.04 (Vivid Vervet) has been out for a while, but I am just now getting it installed.  Here are my notes.


I didn’t take screenshots of all of the steps.  They were pretty straight forward.  The one thing that I did change was the partitioning.  I read that having the Swap partition on the SSD drive will wear it out, so I went ahead and moved it onto the regular drive.

So, here’s what it looked like:



In previous installs, I was using Duplicity/Deja Dup.  This time, I have been using BackupPC for backups.  It is a nice centralized solution that de-dups and compresses nicely.

Now, to restore… The BackupPC FAQ: SSH Setup is a good place to start.

To troubleshoot, I went to the backuppc server, and ran:

$ ssh pistachio
ssh: connect to host pistachio port 22: Connection refused

That tells me that the ssh server is not installed. So, I ran:

sudo apt-get install ssh

On the BackupPC server, I had already run the keygen. So, I just had to open the id_rsa.pub file and copy it’s contents.

sudo vi /var/lib/backuppc/.ssh/id_rsa.pub

Then, on my laptop, I pasted it onto the end of the authorized_keys2 files (which, in my case I had to create):

$ sudo mkdir /root/.ssh
$ sudo vi /root/.ssh/authorized_keys2

Next, I tried to connect to my laptop of the backuppc user on the server:

sudo su - backuppc
sudo ssh root@pistachio

I had to run:

ssh-keygen -f "/var/lib/backuppc/.ssh/known_hosts" -R pistachio

List of Restores

These are the directories that I restored from my backup:

  • ~/Documents: This is where I put all my document files
  • ~/Pictures: I have Shotwell pointed at this directory, so it contains all the pictures from my cell phone and digital camera
  • ~/GideonTaylor: I keep my work files in a different directory
  • ~/app: This has all of my programming stuff (“application development”)
  • ~/.config/google-chrome-beta: The settings for Chrome (extensions, bookmarks, etc)
  • ~/.local/share/keyrings: My saved passwords, see below for more information
  • ~/.Skype: Skype history
  • ~/.remmina: The settings for my remote connections
  • ~/.ssh: The keys for my remote ssh connections
  • ~/.local/share/shotwell: The settings and thumbnails for my photos
  • ~/.sword: The downloaded Bible files for Xiphos (and the underlying Sword library)
  • ~/.filezilla: The settings for my FTP connections
  • ~/.sqldeveloper: The connection settings for SQL developer
  • ~/.vim: stores the plugins installed in Gvim
  • ~/.vimrc: preferences for Gvim  (for my settings, I also had to create the ~/.vimtmp directory)
  • /etc/NetworkManager/system-connections: this saves all of my wireless connections and VPN connections
  • ~/.VirtualBox: The settings for my virtual machines


From here, you can see all the steps that I took in this series, or the next step is the Utilities and Configuration.


More Polymer 1.0 Lessons

I’ve done some more work with Polymer 1.0, so I have some more to share with what I have learned. Specifically, what I was working on was making my home page mobile friendly and also working on a quick program with my son to track license plate states on our road trip.

Installing Zoom Client

Some of my co-workers have been using the Zoom Conferencing Service.  Unfortunately, they haven’t had a Linux client.  That means that I’ve had to start a Windows virtual machine for each meeting.  If I want to share anything on my desktop, I’ve got to get it on my VM.

Well, today, I was given access to the Linux beta client.  It took several emails.  Apparently, I’m not the only one wanting a conferencing solution for Linux.

I followed the directions from Zoom Support.

Here are my notes…

Paychex Tests Patience

I’m not sure what to file this under, but someone needs to know and change this.  Paychex just crossed the line for this end user!  I hope that my software development skills never stoop this low.

I enter time into the Paychex website on a weekly basis, or at least I am supposed to.  The entry page has no totals, so there’s no way to make sure that everything adds up when I get done entering.  The way the web page works is like a website from the 90’s in my opinion.  I had to write a Tampermonkey script just to make the page usable for me.  That right there should be a sign that something is not right.

This week, everything quit working.  I could log in, but before I could get very far, I would get this message:

Web Server Security Alert

This website uses special security software that monitors suspicious network traffic and behavior. If you feel that you have caused this security error unintentionally, please contact our Customer Service Center at the address below and be sure to include all the information below in your message.

Email contact:  tlo@paychex.com
Reference ID:  20150618USTXFA46
Date and Time:  Thu Jun 18 2015 17:28:21 GMT-0500 (CDT).
Web Browser Information:  5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/43.0.2357.125 Safari/537.36



I started troubleshooting by turning off my tampermonkey script.  I even completely disabled the extension.  No luck.  I rebooted the PC and tried several times during the day to make sure it wasn’t a bandwidth issue.

I noticed several of the images on the page were not loading.  So, I popped open the console, and saw all of these errors:

Failed to load resource: the server responded with a status of 406 (Not Acceptable)

Finally, I emailed the address in the original error message.  No response came in the next day or two, and I was told to call 1-877-281-6624 .  Apparently, that was the wrong number, and I was forwarded to 888 246 7500 as the Time and Labor technical support line.

Paychex support’s solution was to clear cache, clear browser history, install the latest version of flash, and add their 5 sites as trusted sites.  That was no help for a Ubuntu user.  Their end solution was since it works in Firefox, I still have a way to enter time, so that’s good enough.

So, I don’t know if this was a Chrome on Ubuntu issue or an issue with the network.  It’s got to be something like that because I seemed the only one affected.

The final straw for me was when I asked about not getting a response back to my email.  “Oh, that email address is no good.”  It’ was almost like “duh, what are you thinking”.  I don’t remember a sorry or anything like that, but maybe I was just upset and missed it.

So, here’s my rant:

  • Why do I have to write my own code in a Tampermonkey script to total the hours?
  • Why do they use flash?  It’s not like the site looks fancy or does any cool features like remote desktop sharing.  It’s just as basic as you get: type some numbers in some fields and hit submit.
  • Why do I have to enter 4 codes for each time that I enter?
  • Why do they have 5 different host names?
  • Why does their error message tell you to email some address that doesn’t work (doesn’t send a reply back, just goes into a black hole)?

Ok, I’m done.  Be warned: if you pick Paychex, your end users won’t like it.  Hopefully, Paychex will wake up and fix things.

Update: It’s beginning to look like Paychex just does not support Linux.  They require Flash.  Adobe says that it doesn’t support Linux anymore.  Also, it is not an issue with the hotel network that I was using.  I am getting the same errors on my home network.

Playing with Polymer 1.0

At the Google I/O conference, they announced the release of Polymer 1.0.  I’ve been wanting to get into Polymer for a while now, and that was the one nudge that I needed.  I decided to take a stab at redesigning my website’s home page with Polymer.

Java Security Exception Site for WebEx

I’ve been having trouble opening WebEx because of a Java error message.  The “security settings have blocked the application”.  Here’s what I did to fix it…

Error message:
