ssh, multiple clients on NAT, known_hosts

from [Peter Gordon] Network Security [Permanent Link]
Subject: ssh, multiple clients on NAT, known_hosts
Date: Sat, 03 Nov 2007 20:21:07 +0200 
ssh -V on Fedora 7
OpenSSH_4.5p1, OpenSSL 0.9.8b 04 May 2006



I have ssh access to computers which sit on a NAT behind a router.
        
        These are the commands I use to access them:
        
        ssh -N -g -R 10000:127.0.0.1:200 user@200.201.202.203
        ssh -N -g -R 10000:127.0.0.1:201 user@200.201.202.203
        
        The router routes port 200 to port 22 on computer 1 and
                          port 201 to port 22 on computer 2.
        
        Starting with a clean known_hosts file, it ask for verification,
        and
        access proceeds.
        
        However, each time I access the other computer, ssh complains
        about the
        entry in the known_hosts file. 
        
        What is a decent workaround for this problem?
        
        Thanks,
        
        Peter
