Hi, Going through Wills workshop in hardening the Server. Ran into first problem when updating on the terminal with apt update && upgrade -y update showed but did not upgrade, so had to run that with sudo upgrade by itself.
Next problem when getting into setting the Firewall. Sudo: ufw command not recognised.:
bluemonkey@racknerd-f82678:~$ sudo ufw allow ssh
[sudo] password for bluemonkey:
sudo: ufw: command not found
bluemonkey@racknerd-f82678:~$
I have gone back to my home terminal and it shows up. This is where I logged out and went to the home terminal
bluemonkey@racknerd-f82678:~$ sudo ufw status
sudo: ufw: command not found
bluemonkey@racknerd-f82678:~$ exit
logout
Connection to 198.74.102.59 closed.
one-hundred@one-hundred:~$ sudo ufw status
[sudo] password for one-hundred:
Status: active
one-hundred@one-hundred:~$
So it sees the command in home, but not on the server.
Thoughts?
