SSH Cheat Sheet
Login via SSH with password (LOCAL SERVER)
$ ssh brad@192.168.1.29
Create folder, file, install Apache (Just messing around)
$ mkdir test
$ cd test
$ touch hello.txt
$ sudo apt-get install apache2
Generate Keys (Local Machine)
$ ssh-keygen
Add Key to server in one command
> cat ~/.ssh/id_rsa.pub | ssh brad@192.168.1.29 "mkdir -p ~/.ssh && chmod 700 ~/.ssh && cat >> ~/.ssh/authorized_keys
Create & copy a file to the server using SCP

DIGITAL OCEAN

Create Keys For Droplet (id_rsa_do)
$ ssh-keygen -t rsa
Add Key When Creating Droplet
Try logging in
$ ssh root@doserver
If it doesn’t work
$ ssh-add ~/.ssh/id_rsa_do
(or whatever name you used)
Login should now work
$ ssh root@doserver
Update packages
$ sudo apt update
$ sudo apt upgrade
Create new user with sudo
$ adduser brad
$ id brad
$ usermod -aG sudo brad
$ id brad
Login as brad
> ssh brad@doserver
We need to add the key to brads .ssh on the server, log back in as root
$ ssh root@doserver
$ cd /home/brad
$ mkdir .ssh
$ cd .ssh
$ touch authorized_keys
> sudo nano authorized_keys
(paste in the id_rsa_do.pub key, exit and log in as brad)
Disable root password login
$ sudo nano /etc/ssh/sshd_config
Set the following
PermitRootLogin no
PasswordAuthentication no
Reload sshd service
$ sudo systemctl reload sshd
Change owner of /home/brad/* to brad
$ sudo chown -R brad:brad /home/brad
May need to set permission
$ chmod 700 /home/brad/.ssh
Install Apache and visit ip
$ sudo apt install apache2 -y
