Streamlining ssh Configuration

By streamlining the ssh configuration, you no longer have to type out ssh « username » @ieng6.ucsd.edu. Instead you can use ssh configuration files to be able to simply use an alias of your choice to log into a server.

Editing .ssh/config

On Visual Studio Code, I opened a new terminal and I used vim as the tool to edit my .ssh/config file by entering vim ~/.ssh/config in my terminal.

Logging Into My Account Using the Alias

On Visual Studio Code, I opened a new terminal and I used the ssh protocol and my alias to remotely connect to the ieng6 server by entering ssh ieng6 in my terminal.

To copy a file into my account using my alias I typed the following scp command into the terminal: scp labReportPart1.java ieng6:~/

Setup Github Access from ieng6

In order to use git commit and git pull from the command line, you must use a token based login so I added my public key to Github. Once I added my public key into Github I was able to use git push from the command line. In order to add my public key into Github I copied the SSH public key, I went to Settings on Github, I clicked “New SSH key” and I pasted my key.
