To remote connect from Linux to Linux, use SSH (Secure Shell). First, ensure SSH is installed on both systems. On Ubuntu or Debian-based systems, install SSH by running `sudo apt-get install openssh-server`. On the remote system, verify the SSH service is running with `sudo systemctl status ssh`. To connect, type `ssh username@remote_host` in the terminal, where `username` is your user on the remote machine, and `remote_host` is the IP address or hostname of the remote machine. You'll be prompted to enter the user's password. For a passwordless connection, use SSH keys.
