Security and SSH

Security.  We all feel a bit of comfort when we know our private information is secure.

What I recently learned:

SSH =  Secure Shell.  When I want to access my EC2 Instance, I need to "SSH" into it.  What exactly does that mean?  I have a private EC2 Key that is located on a file on my computer.  My EC2 Instance has a public key that is located on the home directory of my EC2 Instance.  SSH authenticates my computer to my EC2 Instance to make sure that I am authorized to communicate ( send, transfer, receive, and change files) with my EC2 Instance (my private server on AWS).  Once SSH authenticates my private key to my public key, SSH provides a private secure encrypted environment for my computer to communicate with my EC2 Instance.

"But HOW do you SSH into your EC2 Instance," you might ask?  I can't physically drive to my EC2 Instance,  so I will need to access it using the same command window as I use to look at my own MacBook Pro Computer.  For me, that program is called Terminal.  It is located in the Applications Folder.  Once in my command window (Terminal), I will need to type the command:  SSH and then the location of my private key, then the whither.  This is where the private key needs to goto to meet up with my public key.  This contains the user name of the private key as well as the location (ip address or domain name) of my EC2 Instance.  Here's an example of what that looks like (of course I will use FAKE file names 😊):

ssh -i ~/Documents/Harry/MetSally/PrivateKey.pem PrivateKey-user@wouldntyouliketoknow.com

That is an example of the command I would need to type in order to SSH into my private EC2 Instance.

Once inside, I can communicate with and make whatever changes I want to my EC2 Instance.

SCP =  First successful upload with scp to my webserver.  http://irontreedev.com/ArtesLatinae15.xml

Stay tuned for my next blog on what SCP is!

XPATH and XPATH Expressions In XMLLINT

XPATH And XPATH Expressions Earlier, I told you about xmllint and xmllint for html files .  Let's say you just want to parse the <span> tags within your html file or just your <span lang="el"> tags? Enter:  Xpath. Xpath is yet another option available within the xmllint language. Remember, an Xpath is used to navigate through elements and attributes in xml and html documents.  Xpath uses Xpath Expressions to select nodes or node sets within a document. Example 1 .  Looking for all of the <span> tags within an html document. xmllint -- html -- xpath " // span" StedmanLesson10.html xmllint = This tells the command line that we are going to be using the xmllint language. space = because we always have space in between commands -- = Remember, these are the two hyphen-minus characters that we need to tell the command line that we are going to use an xmllint option. html = This is the xmllint option we want to

Back To The Basics

Click photo above to see photo clearly  It's Been A LOOONG Minute since I have coded!!   Even so, I decided to give JavaScript another try.  I always seem to do good and then when I get to this one area, I always seem to hit a brick wall.  Well....nothing like getting back up and trying again right?   I decided to try Rithm School's online JavaScript Fundamentals FREE course .  I have never joined their school but their free courses tend to explain things in a way my brain understands it.  💁 To let you know how much I have forgotten in the coding world, I couldn't even remember how to write the basic commands for an HTML document! Yesterday I started the fundamentals free course and I am so glad that I did.  Because of time, I only made it through the JavaScript History and Setup chapter, but that chapter was enough to get my memory flowing again!   It started to feel familiar and I quickly remembered why I enjoyed coding so much.  Yesterday and this morning, I just erased

GIT Commands: Pull, Add, Commit, Push.....and sometimes Revert

Pull, Add, Commit, Push ...... then Repeat We talked about GIT, GIT Hub , and the three different areas GIT works in.  Now it is time to talk about some of the most used GIT commands.   I am currently working with a team on a project called Stedman.  We are all using the GIT Hub server to track our work as we make changes to the files within the Stedman project.   Many changes can be made by other members of the team, from the time I sign off to the time I sign back on.  How do I get the changes they made to a file I need to work on, onto my computer? ENTER GIT COMMANDS : 1.  The first thing I do is goto my command window on my computer and navigate to the directory where the file I want to work in is located (this will be a directory that is being tracked by GIT).   *If you need a quick refresher:  cd file_name   will take you through each of your directories until you reach your desired location.  Issuing an  ls   command will list the files (sub-di
