Ssh - Terminal

  • Theory
    • Secure Shell
    • Communication Protocol (Like http, https, ftp)
    • SSH is the client, SSHD is the server
  • Authentication Methods => ssh hostName@IPAddress
    • Password
    • Public/Private Key Pair
    • Host Based
  • Generating Keys
    • ssh-keygen
    • Private Key will be at "~/.ssh/id_rsa"
    • Public Key will be at "~/.ssh/id_rsa.pub"
    • Public Keys goes into Server "authorized_keys" file
    • Putty & Git Bash like Terminals can be used
    • cat .ssh/id_rsa.pub => Show public key
    • cat ~/.ssh/id_rsa.pub | ssh hostName@IPAddress "mkdir -p ~/.ssh && chmod 700 ~/.ssh && cat >> ~/.ssh/authorized_keys" => Add Key to server in one command
    • hostName@IPAddress => Connect without Password
    • cat .ssh/authorized_keys => Key should display
    • touch test.txt => Create a file
    • scp ~/test.txt hostName@IPAddress:~ => Copy a file to the server using SCP
  • GitHub
    • ssh-keygen -t rsa
    • ssh-add /home/brad/.ssh/id_rsa_github
    • eval ssh-agent -s
    • Clone repo
    • Install Node
    • npm install
    • $ npm start
  • Build Out React App
    • npm run build
    • sudo mv -v /home/brad/react_otka_auth/build/* /var/www/html => Move static build to web server root
