    59  This type of error happens when you have previously logged in a machine with the same IP address and that machine happens not to be the same one as the VM you want to log in. [[BR]]
    60  As a result, this error might happen a lot, especially if you have done experiments on ExoGENI before (since it always uses the same IP range for its VMs and each VM is different from each other, i.e., with different RSA keys). [[BR]]
    61  In this case, simply open ''~/.ssh/known_hosts'' and remove the line corresponding to the IP address you are trying to login. In our case here, find ''192.1.242.65'' and remove that line. [[BR]]
    62  '''Note that the nodes are ready to login does not mean the interfaces are up and well configured. Users may need to wait for up to 5 minutes after nodes are up. '''
