    Hi all:
        I have used ssh for my work and encountered a problem.The scenario is:
        Remote machine is, the working account is tercel
        Local machine is, the working account is chenjian
        I generate a pair of key in local machine with command ssh-keygen -t
    rsa1 under account chenjian and get two files:identity and
    Then I append to file authorized_keys under in remote machine.
        Then I used command ssh -1 -v tercel@ and get error"
    major versions differ: 1 vs. 2".

        Can anyone help me explain this problem and give an answer to it?

    Best Rgds!
