I usually have to access a couple of remote and local SSH hosts, this works perfectly, I actually want to have to type in the passphrase every time.
However, there's a single SSH host on my local network that I have to log into a lot more frequently than the rest. Security is not much of a problem with this one in particular, although connecting without keys is out of the question. Is there any kind of configuration which would allow me to not enter the passphrase for this single SSH host?
I hope I'm not asking something that doesn't even make sense...
Edit: I apologize for not clarifying, every server and my client are running Linux, there's no other OS involved in any way.
