Ok so I've done a bit of googling and haven't come across an answer.
We have multiple servers in our environment and around 5 infrastructure servers.
Then we have one server that we can ssh to all the normal servers.
Now I want to create unique ssh key's for each individual infrastructure server, so that they cannot be accessed with the default ssh key.
The aim is to be able to specify which ssh key to use for which infrastructure server on the command line while sshing to the infrastructure server.
I am not sure where to start and do not want to interfere with the trust for the normal servers.
Can anyone point me in the right direction?
Thanks in advance!
