Ubuntu Rest Assurer

Before I'll start talking about this utility I would like to talk about the story behind the creation of this utility. Few days back we have a session ERGONOMICS about healthy lifestyle, one of the main thing was that a person should take a break after every 20 minutes. After the session I was having a chit chat about one of my colleague Rahul Narang & we were discussing about this 20:20:20 rule & then we thought about creating a utility that will force a person to leave his/her system after some stipulated time & that's how the idea came about this utility.

So what this utility does
1.) It runs after every half hour or configured amount of time
2.) Prompts a snoozer dialog box which will allow a person to snooze the screen locking for some amount of time
3.) After that a lunching video will run for 10 seconds
4.) Once a lunching video completes the screen gets locked for a configured amount of time
5.) If user try to unlock the system before configured amount of time the utility will lock the screen again

This complete utility is created using shell script only, we have used couple of command to do that
vlc : To run a launcher video
zenity : To prompt a snooze dialogue box
gnome-screensaver-command : To operate on screen lock

You can find the source code of this utility at my github account

EC2 Ssh Connection Refused

When ssh: connect to host ip_address port 22 Connection refused

Unable to access server???
Exactly when you see the error - “ssh: connect to host ip_address port 22: Connection refused” while connecting your AWS EC2 Instance. In order to find solution of the problem, you will go to AWS forum and other channels where you need to answers several questions first. But it's very difficult to find the actual problem. In order to get clues what the problem is, we should provide as many details as possible about what we have tried and the results we are getting. Because there are hundreds of reason why a server or service might not be accessible, also connectivity is one of the toughest issue to diagnose, especially when you are hosting something critical on your box. I've seen several topics on this problem, but none offers a solution to it.  I was not aware for what should I look at first. So I walk through from the very basics and investigated the following thing Use of verbose while ss…

jgit-flow maven plugin to Release Java Application

Introduction As a DevOps I need a smooth way to release the java application, so I compared two maven plugin that are used to release the java application and in the end I found that Jgit-flow plugin is far better than maven-release plugin on the basis of following points: Maven-release plugin creates .backup and files to your working directory which can be committed mistakenly, when they should not be. jgit-flow maven plugin doesn't create these files or any other file in your working directory.Maven-release plugin create two tags.Maven-release plugin does a build in the prepare goal and a build in the perform goal causing tests to run 2 times but jgit-flow maven plugin builds project once so tests run only once.If something goes wrong during the maven plugin execution, It become very tough to roll it back, on the other hand jgit-flow maven plugin makes all changes into the branch and if you want to roll back just delete that branch.jgit-flow maven plugin doesn…

VPC per envrionvment versus Single VPC for all environments

This blog talks about the two possible ways of hosting your infrastructure in Cloud, though it will be more close to hosting on AWS as it is a real life example but this problem can be applied to any cloud infrastructure set-up. I'm just sharing my thoughts and pros & cons of both approaches but I would love to hear from the people reading this blog about their take as well what do they think.

Before jumping right away into the real talk I would like to give a bit of background on how I come up with this blog, I was working with a client in managing his cloud infrastructure where we had 4 environments dev, QA, Pre Production and Production and each environment had close to 20 instances, apart from applications instances there were some admin instances as well such as Icinga for monitoring, logstash for consolidating logs, Graphite Server to view the logs, VPN server to manage access of people.

At this point we got into a discussion that whether the current infrastructure set-u…
