Simplifiying SSH

Nowadays we are use to deploy code in the cloud and to have all our machines and servers in cloud environments. All of this, it has even made more important the use of ssh to connect remotely to our servers allocated in the cloud.

I have written multiple times in my console the commands to connect to one server or another but, as every developer, I am lazy and I try to simplify my life. In this case, we can do this with a simple lines in a couple of files:

  • ~/.ssh/config: We are going to configure the machines we want to connect or tunnels we wnat to create.
  • ~/.bashrc or ~/.bash_profile: Create some alias to easily connect to our servers

SSH config file

Server to connect

# MyServer-1
Host                    myServer1
User                    username
IdentityFile            ~/.ssh/myCertificate.pem PasswordAuthentication  no
StrictHostKeyChecking   no

Create tunnel

# MyServer-1 - myDb
Host                    myServer1Db
User                    username
IdentityFile            ~/.ssh/myCertificate.pem PasswordAuthentication  no
StrictHostKeyChecking   no
LocalForward            3307

Bash Config file

alias myserver1="ssh myServer1" alias myserver1db="ssh myServer1Db"


After this, it will be enough to connect to our remote servers with executing our aliases in our console. No more remember commands.

Publishing to GitHub

GitHub is a web-based Git or version control repository and Internet hosting service. As a developers, I am quite sure that all of you know the platform.

Every-time we start a new project, even if it is just something for us, it is a good idea to use a version control system. Here is where Git and GitHub can help us.

There are two easy ways to create and upload our project to a repository.

The first way, it is to create the repository in GitHub, and after that clone in our machine the created repository and start writing our code. This is the simplest way. Doing it in this way, our local repository is already connected to the remote repository and we just need to start committing things. The clone command, assuming the account name is “fjavierm” and the repository name is “myproject”,  is:

git clone

Te second way, it is when we already have a project in our local machine and we want to add the project to a repository. In this case, we need to perform a few more steps.

  1. We need to create the repository under our GitHub account. In this case, my account is “fjavierm” and my repository is going to be “myproject”.
  2. In our local machine, in our local project folder, we need to initiate the git repository. This will add a folder “.git”: init
  3. We can check the status of the available files: status. This instruction will show us the files that we can add to the repository to commit. In this step, it deserves to pay special attention to the files that we do not want to add and, maybe, it is a good idea to create the files “.gitignore” and “”
  4. Add the files to the repository.
  5. Commit the added files adding a descriptive message. Usually, issue number and description, or something meaningful.
  6. Connect our local repository with our remote repository.
  7. Check we have perform the previous step properly.
  8. Push our changes to the remote repository.
git init
git status
git add .
git commit -m "Starting the project."
git remote add origin
git remote -v
git push -u origin master

With these few instructions we should have available all our code in the GitHub repository.
