SSH

Create SSH keys

ssh-keygen -t rsa -b 4096 -C "your_email@domain.com"

ssh-keygen -t ed25519 -C "your_email@example.com"

Create reverse SSH tunnel

• From distant machine

ssh -R {local_machine_port}:localhost:22 {user}@{local_machine_ip}

• From local machine

ssh {distant_machine_user}@localhost -p {local_machine_port}

Redirect distant port to local machine

• From local machine

ssh -L {local_machine_port}:localhost:{distant_machine_port} {user}@{distant_machine_ip}

Copy files

• From local to distant

scp {local_file_path} {user}@{distant_machine_ip}:{desired_distant_path_to_file}

• From distant to local

scp {user}@{distant_machine_ip}:{distant_path_to_file} {desired_local_path}

Remove ssh known_hosts entry

ssh-keygen -R {hostname}

Setup a ssh socks proxy and use it with chromium

1. Setup the connection

ssh {user}@{ip} -D {local_port}

2. Start chromium with the proper flag

chromium --proxy-server="socks5://localhost:{local_port}"

Forward SSH agent to remote machine

1. Add RSA or DSA identities to the authentication agent ssh-add {path_to_identify:optional}
2. Connect to the remote server ssh -A {user}@{host}
3. Check if it works by calling github (ur key must be known by GitHub ofc) ssh -T git@github.com
