In this post we are going to fingerprint between esxi servers 4.1 to build trust between them and not rely on a validation request. With all this we can make ssh connections between them without being stopped asking for credentials.

We create the .ssh address in the root and generate the public key that will be the one that will be carried by the rest of the trusted servers.

mkdir /.ssh

cd /.ssh

dropbearkey -t rsa -f key

dropbearkey -f key -y | Head -n2 | tail -n1 >key.pub

scp key.pub root@IP_DESTINO:/.sh

and we validate ourselves

Once copied, on the destination server we rename it to authorized_keys

MV Key.pub authorized_keys

We check that it works by copying any file by ssh without asking us for the credentials.
