&gt;&gt;&gt;If I ever reference a host on a ssh command by an alternate name, it &quot;fails&quot; 
&gt;&gt;&gt;with a message warning about the possibility of a man in the middle attack.  
&gt;&gt;&gt;Is there any way to tell ssh to not pester me about this, or to list several 
&gt;&gt;&gt;hostnames for the same RSA key?
