new key?

[Chris Aitken]

I am trying to copy files from my machine (p733) to the machine I just 
installed FC2 on (a800).

I'm getting the following:

[root at p733 chris]# scp -r /backupdrive/a800buonp733/paulinework 
pauline-Q0ErXNX1RuZDlWMHxMKk0g at public.gmane.org:/home/pauline/paulinework

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is

Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.

RSA host key for 192.168.0.3 has changed and you have requested strict 
checking.Host key verification failed.
lost connection

I have no experience with keys.

Am I getting this because I set up the firewall on the new installation?
