sshd --helpIt will print out its OpenSSH version and some usage info (since --help is not a valid option). You should see a string like this:
OpenSSH_8.2p1 ....That's the OpenSSH version. Check it against the ranges that are vulnerable. If yours is not vulnerable then you're okay. If your is potentially vulnerable, use a command like the one ShadowAce posted above in #12:
sudo apt update && sleep 2 && apt list --upgradable
Thank you. Will give it a go tonight.
ran the command and it said SSh wasn’t installed, so my system wouldn’t be vulnerable then?
