问题解答
回答1：经过我的搜索，问题解决了参考这两个链接https://blog.flameeyes.eu/2011/01/mostly-unknown-openssh-trickshttps://blogs.oracle.com/janp/entry/ssh_messages_code_bad_packet以下是修改后的~/.ssh/config配置
Host coding.netHostName coding.netUser myemail@mydomain.comIdentityFile /home/honwhy/.ssh/coding_rsaProtocol 2ControlMaster autoControlPersist yes
这两行配置比较重要
ControlMaster autoControlPersist yes
第一次链接时还是会提示错误，第二次链接就可以正常连接了。详细过程真的应该去读读手册、或者RFC，第二个链接中也说得很具体了。
THE END
