Ubuntu-12.04-64-bit-16Gig-WCS-DEMO-disk1.vmdk

"C:\Program Files\Oracle\VirtualBox\VBoxManage" clonehd "Ubuntu-12.04-64-bit-16Gig-WCS-DEMO-disk1.vmdk" "cloned.vdi" --format vdi
"C:\Program Files\Oracle\VirtualBox\VBoxManage" modifyhd "cloned.vdi" --resize 51200
"C:\Program Files\Oracle\VirtualBox\VBoxManage" clonehd "cloned.vdi" "Ubuntu-12.04-64-bit-50Gig-WINT-MLR-disk1.vmdk" --format vmdk

Installing MongoDB in Ubuntu 12.04

Unable to install latest version in Ubuntu 12.04
Refer: http://gordoncluster.wordpress.com/2013/07/12/how-to-install-mongodb-on-virtualbox-ubuntu-12-04/

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10
echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | sudo tee /etc/apt/sources.list.d/10gen.list
sudo apt-get update

We're going to specifically install an older version (you will need to run this as root):
sudo su -
apt-get install mongodb-10gen=2.2.3

The service should already be running, the output: mongodb start/running, process 2254
sudo service mongodb status | stop | start

now we just run:
mongo

The output you should see is:
MongoDB shell version: 2.2.3
connecting to: test

Using canned mockup with booking flow

Refer: https://www.npmjs.org/package/canned

  • $ npm install canned
  • Unzip canned responses in bookingflow folder canned.zip
  • Update configuration.js file
    cmsUrl: 'http://localhost:3000/hal-cms',
    dsUrl: 'http://localhost:3000/hal-ds',
  • Launch canned server from root of bookingflow, default port is 3000, left here for documentation
    ./node_modules/canned/bin/canned -p 3000 ./canned

Limitation, rest calls that return images do not work properly.

Example on how to define a call

  • You will need to determine if it is a get or a post to generate the proper index file of either index.post.json or index.get.json, see the last statement of example
  • Use chrome to get the URL of the rest call, and then also to get the curl version of the rest call
  • You can string all of these together and create a bash script to do everything at once

mkdir -p /home/mruckman/Documents/bookingflow/canned/hal-ds/rest/pricing/v1.0.0/companyCode/HAL/cpp/countryCode/US

cd /home/mruckman/Documents/bookingflow/canned/hal-ds/rest/pricing/v1.0.0/companyCode/HAL/cpp/countryCode/US

curl 'https://qabook.hollandamerica.com/hal-ds/rest/pricing/v1.0.0/...

Use Python to format JSON

Easier way to format JSON instead of JSONLINT

With Python 2.6+ you can just do:
echo '{"foo": "lorem", "bar": "ipsum"}' | python -mjson.tool

Citrix Receiver in Ubuntu

Download the receiver from the Citrix site:
http://www.citrix.com/downloads/citrix-receiver/linux/receiver-for-linux-130.html

So, you've upgraded Firefox on Ubuntu and Citrix no longer works, well do the following:

  • uninstall Firefox
  • install Firefox
  • $ sudo rm -rf /opt/Citrix/ICAClient/keystore/cacerts_old
  • reinstalled Citrix
  • redo the Citrix installation steps below
  • When you launch Citrix, make sure you ALLOW pop-ups, if asked!

Here are the steps to install Citrix for the first time:
For Ubuntu you will need to download the *.deb version and install through the software center

Now you need to get the certs to work properly in Firefox:
Refer: https://www.geekpete.com/blog/ssl-error-61-using-citrix-ica-client-on-linux/

You are going to copy the certs and create a symbolic link for all of the certs then:
$ sudo mv /opt/Citrix/ICAClient/keystore/cacerts /opt/Citrix/ICAClient/keystore/cacerts_old
$ sudo cp /opt/Citrix/ICAClient/keystore/cacerts_old/* /usr/share/ca-certificates/mozilla/
$ sudo ln -s /usr/share/ca-certificates/mozilla /opt/Citrix/ICAClient/keystore/cacerts
