    尝试使用-v进行ssh。输出为:

    我没有权限访问一些ssh相关文件。

    ls -al /home/ccc/.ssh/known_hosts
    -rw------- 1 root root 7770 Jan 20 16:14 /home/ccc/.ssh/known_hosts
    

    获取权限:

    ccc@es-chen:~$ sudo chown -R ccc:ccc .ssh
    ccc@es-chen:~$ ssh cccadmin@ccchost -A -X 
    The authenticity of host 'ccchost (myip)' can't be established.
    ECDSA key fingerprint is 17:d5:07:c8...............:54:5e.
    Are you sure you want to continue connecting (yes/no)? yes
    Warning: Permanently added 'ccchost,myip' (ECDSA) to the list of known host
    

    现在确定
