Getting Started with Git: Creating a Git Repo

NettutsFetch-1So first off let me start by saying that I know that there is a ton of information out there on how to get started with Git. Heck, when you create your repo in GitLab it spits these instructions right out in front of your nose. However, what I have found is that most instructions tell you what to do to get started with git, however they do not tell you exactly what you are doing. You end up running a few command and then sit back and try to figure out what you actually just did.

 

That being said, getting started with Git has been the hardest part of the process, as most of us traditional grey-beard sysadmins are not that familiar with code management. When I was first getting started in technology, there were developers and there were sysadmins, and those two worlds were extremely separate. Now, we as we enter the age of DEVOPS and automation these two worlds are once again colliding (like they did in the beginning, but more on that another day).

 

 In my lab I decided to build a stand alone vm for Git and Puppet. After doing some research – and asking others– on how and what to do to get Git up and running with a nice front end web interface, I decided to get started by installing the GitLab Omnibus package for Centos 6. This process was quick, easy, and painless.

 

Once I had a working webUI up and running it was time to create my first repo. Instead of trying to accomplish this from my Fedora workstaion, I just clicked on the "New Project" button on the GitLab dashboard and created an empty repo called "General_Scripts".

 

Back on my Fedora workstation I created a new directory in my home dir called git, and inside that directory I created a directory called "General_Scripts" as I had done in the webUI.

 

Now it was time to use Git.

 

First off you need to configure a few global Git options. This only needs to be done once.

#git config –global user.name "Fatmin"

#git config –global user.email "fatmin@fatmin.com"

 

Once these global configs are set you can then you can move on to seeding your repo. Here you see my change directories to the Global_Scripts directory and tell Git to initialize this directory as a repo.

#cd Global_Scripts

#git init

 

Now lets create a file and add it to the repo. Here were are going to create a simple README containing a description of my new repo. The instructions do not tell you that you have to put anything in this initial file, however what good is an empty README anyway

#vi README.md

 

Now tell git that this file needs to be added to the "General_Scripts" repo that we created a few steps ago.

#git add README.md

 

Now lets commit that file with a nice little comment. Commit comments should describe what the file we added or what we changed in an existing file

#git commit -m "Added README.md"

 

Now we need to tell our local git command what remote repo we are going to sync to. Note my git repo url is puppet.lab.localdomain, fatmin is my user's namespace, and General_Scripts is my repo.

#git remote add origin git@puppet.lab.localdomain:/fatmin/General_Scripts.git

 

Now we need to actually push the local files to the remote repo (origin) in the master branch.

#git push -u origin master

 

Now wait a bit and go check out the webUI. You should now see the README.md file in your new remote repo.

Install and Configure SNMP on the Asus RT-AC66U Router

ASUS_RT-AC66U_newsOk first off let me start by saying that this is probably the coolest piece of home computing hardware that I have ever laid my hands on. Yes the setup was easy, and yes the thing is rock solid, and yes wireless range is awesome. But for approx $200 USD you really should not expect anything less.  I’m not going to go into its specs or features, as I’ll leave that to the professionals. Read up on it here.

Anyway out of the box it supported telnet, but I wanted ssh, so I dropped the default firmware and went with Asuswrt-Merlin. It was at this point I started to explore the Busybox OS and decided I wanted to monitor the device via my HomeLab Zenoss install.

However, much to my chagrin net-snmp was not installed out of the box.

So how do you install it you ask? Would you believe via a package manager?

First, you need to find the package name

#ipkg list | grep snmp

Then install the snmp package

#ipkg install net-snmp

Then configure it to start at boot time.

#app_set_enabled.sh net-snmp yes

In order to configure it, you are going to have to search for the snmp.conf

#find / -name snmpd.conf

I found two files and one of them clearly states that you should not edit it directly. The other one does not so this is the one that I modified to include my custom rocommunity. See below.

rocommunity  lab

Now I just need to figure out how to allow port 161 udp/tcp on my local LAN segment and I am in business. However, I will probably tackle that tomorrow.

 

Additional Info (2016)

Note, you can restart snmp as shown below.

Stopping:

admin@RT-AC66U:/tmp/home/root# app_stop.sh net-snmp
killall: dm2_transmission-daemon: no process killed
killall: asus_lighttpd: no process killed
killall: dm2_snarfmaster: no process killed
killall: dm2_nzbget: no process killed
killall: dm2_amuled: no process killed
iptables: No chain/target/match by that name
iptables: Bad rule (does a matching rule exist in that chain?)

Starting:

admin@RT-AC66U:/tmp/home/root# app_set_enabled.sh net-snmp yes
The field(Enabled) was set “yes” already.
Restarting the package…

 

2016 Update – Configuring SNMP via the WebUI

Figured that I would add an update to this post as it seems that there are plenty of folks who are looking to setup SNMP on their Asus routers. Note that SNMP can now be configured directly from the WebUI.

In the left pane, click on “Advanced Setting”. Then click on the “SNMP” tab. See example below. Note that the webui does not seem to pick up your configuration if you have configured it via the cli. I have not tested to see if the WebUI overwrites the CLI configuration or if it creates another configuration file.
