Ssh Access Through Keys

To continue the path on my homelab the most secure i can, we want right now to generate access keys in our laptop and put them in the server. When accessing through SSH, the server is going to check first if the ip is allowed in UFW and then, if who’s accessing has the compatible keys.

With this we should eliminate the password for accessing (or not?)

This really makes me feel completing a great task, i’ts been great so far!

for this all we need to do is:

sudo ssh-keygen -t rsa -b 4056 -f ~/.ssh/81_key

then we must copy this generated key, into the right folder inside the server

ssh-copy-id -i ~/.ssh/81_key.pub pozzi@10.0.0.115

If you decide to eliminate the password access, the server will still be secured by the keys, and for testing it’s ok, but in production, the both authentications together makes a better secure

sudo vim /etc/ssh/sshd_config

Look for the line PassWordAuthentications, and change the value to “Yes” exactly like this bottom example

Make a test and it works!!
