JNCIE-ENT Labs

Purpose

This repository exists as a central location for labs written by people during their quest for the JNCIE-ENT exam. These labs exist in a BSD-license compliant form. Please see the license file for licensing details and permissions.

Contributing

If you wish to contribute, please open an issue as a pull request against this repo in GitHub and title the issue appropriately.
Enter a description of your lab and the request will be reviewed.

To ensure successful acceptance, please submit your lab with the following:

• A new directory specifically for your lab
• PNG- or PDF-formatted lab diagram
• Markdown-formatted lab exercise
• Initial configuration files for each device
• Solution configuration files for each device

At your discretion, you may include a walkthrough of the solution, but this is not required. You may also organize your subdirectory however you wish, although it's recommended that your configuration files remain in a subdirectory of your lab.

Contribution Notice

Any labs submitted must be compliant with this repositories license. Do NOT submit any labs for which you are not the original author or do not have the original author's express permission!

Getting the Labs

At this time, as the labs are in a constant state of flux, the best way to obtain them is with git. While there are graphical clients for git, this section only discusses the command-line method for cloning this repo.

This assumes you are using Linux or Mac OS X and already have git installed. Further, this assumes you are familiar with using the terminal on your OS of choice.

To start, open your terminal application and create a new directory for your git repos. Skip the mkdir step below if you already have such a directory. Then, move into that directory. Finally, clone this repo into its own directory.

cd ~
mkdir git && cd $_
git clone https://github.com/JNCIE-labs/ENT.git jncie-ent-labs

Now you have a current (as of the entry of those commands) version of this repo. To update the repo, use the git pull command, as below.

cd ~/git/jncie-ent-labs && git pull

Daily updates are recommended. This will save you from constantly checking for updates to the branch and manually pulling them. On Linux and OS X, you can use cron to automatically perform a specified command, series of commands, or script at specific intervals. To do this, you will need to create a crontab entry and configure that entry to change to your directory for this repo and issue the git pull command. From your terminal application, enter the following commands:

This will open a crontab editor using your EDITOR environment variable. This guide assumes your editor is vi or vim. If not, you probably know how to save and close the file. nano will tell you at the bottom of the screen.

crontab -e
i
0 0 * * * cd ~/git/jncie-ent-labs && git pull
[esc]
:wq

The Future

The organizers would like to see this become a full JNCIE-ENT lab workbook for future candidates. A community-driven, freely available workbook could significantly aid candidates on a budget or who might need to decide between which books are most vital.

At this time, this repo is not ready to be considered a book or a replacement for any lab guide or workbook. Although the plan is to get to that point, there is currently not enough material. Please contribute if you'd like to see that change.
