我正在尝试使用 ssh-copy-id 复制公共 ssh，但它会关闭连接：
user@serverA:~/ctm/cm/AFT/data/Keys$ ssh-copy-id -p 1222 -i /home/user/keys/serverA.pub vivek@serverB
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/user/keys/serverA.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
