当我尝试通过 ssh 连接特定服务器时，我收到：连接被 10.5.8.1 关闭（更多详细信息请见后文）
我看到了很多与我类似的错误，但是似乎对其他人有效的解决方法在这里不起作用。
解决方法包括减少密码选项，以减少服务器和客户端之间的查询/响应流。[1，2还有更多，但我不能发布超过 2 个链接...]
这是我的 ~/.ssh/config 之后
Host *
SendEnv LANG LC_*
HashKnownHosts yes
GSSAPIAuthentication yes
GSSAPIDelegateCredentials no
Ciphers aes128-ctr,aes192-ctr,aes256-ctr,arcfour256,arcfour128,aes128-cbc,3des-cbc
这是 ssh 连接日志的结果

显然，我使用默认配置进行测试，在我的 ~/.ssh/know_hosts 文件中删除该服务器的条目，尝试为 ssh 找到一个名为 paramiko 的库但没有成功，尝试一次只放一个密码...我没有更多的想法了。
我无法访问远程服务器。我正在Linux pfa-fedora 3.16.6-200.fc20.i686 #1 SMP Wed Oct 15 13:48:38 UTC 2014 i686 i686 i386 GNU/Linux
