i cannot make it work. i tried the first option but i think i can never make it work like that because as soon as server_float is down then i need to re-authenticate the keys on the last active server. so i tried to the second suggestion, to define a separate key for server_float but i dont seem to make it correctly. this is the steps that i followed so correct me if i missed anything: 1. from the server that server_float is active i copied the keys ssh_host_rsa_key ssh_host_rsa_key.pub and i give them a separate name 2. i added the new key ssh_host_rsa_CLUSTER_key on sshd_config file and restart sshd services 3. server_float is made inactive from server1. i send the new keys ssh_host_rsa_CLUSTER_key ssh_host_rsa_CLUSTER_key.pub on server2 under /etc/ssh 4. i added the key ssh_host_rsa_CLUSTER_key on sshd_config file on server2 and restarted the sshd services. 5. i activate server_float on server2 however, when i try to connect to server_float when it is active on server2 i get prompted to re-authenticate the connection. did i miss anything?

SSH-KEYSIGN(8)						    BSD System Manager's Manual 					    SSH-KEYSIGN(8)

NAME

     ssh-keysign -- ssh helper program for host-based authentication

SYNOPSIS

     ssh-keysign

DESCRIPTION

     ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during host-based authentication with
     SSH protocol version 2.

     ssh-keysign is disabled by default and can only be enabled in the global client configuration file /etc/ssh/ssh_config by setting
     EnableSSHKeysign to ``yes''.

     ssh-keysign is not intended to be invoked by the user, but from ssh(1).  See ssh(1) and sshd(8) for more information about host-based authen-
     tication.

FILES

     /etc/ssh/ssh_config
	     Controls whether ssh-keysign is enabled.

     /etc/ssh/ssh_host_dsa_key
     /etc/ssh/ssh_host_ecdsa_key
     /etc/ssh/ssh_host_rsa_key
	     These files contain the private parts of the host keys used to generate the digital signature.  They should be owned by root, read-
	     able only by root, and not accessible to others.  Since they are readable only by root, ssh-keysign must be set-uid root if host-
	     based authentication is used.

     /etc/ssh/ssh_host_dsa_key-cert.pub
     /etc/ssh/ssh_host_ecdsa_key-cert.pub
     /etc/ssh/ssh_host_rsa_key-cert.pub
	     If these files exist they are assumed to contain public certificate information corresponding with the private keys above.

SEE ALSO

     ssh(1), ssh-keygen(1), ssh_config(5), sshd(8)

HISTORY

     ssh-keysign first appeared in OpenBSD 3.2.
