I heard from GitHub Two-Factor Authentication](https://github.com/blog/1614-two-factor-authentication) nearly a couple of days ago when I was reading my RSS feed. I enabled it and couldn' push to any of my repositories anymore. Learn in this blog post how to fix it.

Two-Factor Authentication

"Is a process involving two stages to verify the identity of an entity trying to access services in a computer or in a network". Github solves this authentication with sending an SMS to a device which wants to push to their platform.

Whether you're trying to give back to the open source community or collaborating on your own projects, knowing how to properly fork and generate pull requests is essential. Unfortunately, it's quite easy to make mistakes or not know what you should do when you're initially learning the process. I know that I certainly had considerable initial trouble with it, and I found a lot of the information on GitHub and around the internet to be rather piecemeal and incomplete - part of the process described here, another there, common hangups in a different place, and so on.

In an attempt to coallate this information for myself and others, this short tutorial is what I've found to be fairly standard procedure for creating a fork, doing your work, issuing a pull request, and merging that pull request back into the original project.

Creating a Fork

Just head over to the GitHub page and click the "Fork" button. It's just that simple. Once you've done that, you can use your favorite git client to clone your repo or j

	Question:
	Hello,

	I often set up vpn tunnels on different network devices(cisco, juniper) and one day I read an info about MTU:

	because of perfomance issues its better practise to reduce MTU size on tunnel interfaces/egress interfaces of routers.

	How this is affect perfomance?

	1. Setup a project

	2. Add groovy SDK support:

	3. Download http://(yourjenkinsurl)/job/(yourpipelinejob)/pipeline-syntax/gdsl
	- this will give you the .gdsl file - download this to the src folder of your project.

	4. Finally follow this step - right click on the src folder -> Mark directory as -> Sources Root
