problem setting up ssh connection


hi,
I have got two computers (server1, server2) running redhat linux 7.3, i wish to log into one of the computers from the other through ssh connection but when i hit ssh server2 from the server1 prompt as root it says "the authenticity of host cannot be established ...are u sure u want to continue y/n - if i give it a yes it still continues asking me y/n and after a few repetetions it says "host key verification failed", since i am a newbie i am not sure what this is due to.. i even tried doing ssh localhost and it behaves in the same manner giving the same error.I would like to turn ssh on and then check out the scp tool for remotely copying files.I would greatly appreciate your help.
Thanx

It looks as though you are not going to get a reply to this so I will try to help even if I am far from an expert.

My guess is that the server on the remote machine is set up to only accept a login with secure public/private key encryption. This is a very convenient, secure and easy way of using ssh. There is an excellent explanation at http://www.steidler.net/uptime/archives/000391.html

If you do not want to use this method (and there is no need for encryption if it is just for two computers in the same location) you must reconfigure the sshd on the remote machine. Start by taking a look at /etc/ssh/sshd_config. Mine is listed below.

ZB

# Set this to 'yes' to enable PAM keyboard-interactive authentication
# Warning: enabling this may bypass the setting of 'PasswordAuthentication'
#PAMAuthenticationViaKbdInt no

X11Forwarding yes
#X11DisplayOffset 10
#X11UseLocalhost yes
#PrintMotd yes
#PrintLastLog yes
#KeepAlive yes
#UseLogin no
UsePrivilegeSeparation yes
#PermitUserEnvironment no
#Compression yes

#MaxStartups 10
# no default banner path
#Banner /some/path
#VerifyReverseMapping no

# override default of no subsystems
Subsystem sftp /usr/lib/ssh/sftp-server
PermitRootLogin yes
