My Most Commonly Used SSH Configurations and Their Uses
A quick overview of my most frequently used SSH configurations and their uses.
Install SSH
Arch
sudo pacman -Syu sudo pacman -S openssh
Debian
sudo apt update sudo apt install openssh-client openssh-server
Check SSH daemon status
sudo systemctl --user status ssh-agent.service
Start SSH on boot
sudo systemctl enable sshd.socket
Generate an SSH key
Using SSH keys instead of passwords is way more secure.
For remote machines
ssh-keygen -t ed25519 -f ~/.ssh/keyName
For version control
ssh-keygen -t keyName -C "[email protected]" -f ~/.ssh/keyName
Copy SSH key to remote machine
ssh-copy-id -i ~/.ssh/keyName.pub user@host
Create SSH Config file
Host someHost HostName someHostname User userName IdentityFile ~/.ssh/sshKeyName Host someHost HostName someHostName User someUserName IdentityFile ~/.ssh/sshKeyName
Execute remote commands
ssh remote-machine -t '<command>'
