Veendume, et SSH-serveri teenus töötab ja on seetõttu ka juba paigaldatud.

Kui on teade:

Active: active (running)

… siis SSH-server töötab.

Vajadusel OpenSSH serveri paigaldamine

# metapakett ssh, mis paigaldab nii kliendi kui serveri:
sudo apt update && sudo apt install ssh && sudo apt clean

# vajadusel ainult server:
sudo apt update && sudo apt install openssh-server && sudo apt clean

# on ka eraldi pakett openssh-client
# otsida saab:
apt-cache search openssh|grep openssh
