Hi all:
    I have used ssh for my work and encountered a problem.The scenario is:
    Remote machine is 192.168.0.8, the working account is tercel
    Local machine is 192.168.0.7, 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 identity.pub.
Then I append identity.pub to file authorized_keys under in remote machine.
    Then I used command ssh -1 -v tercel@192.168.0.8 and get error" Protocol
major versions differ: 1 vs. 2".

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

Thanks!!
