I have changed the file sshd_config under /etc/ssh/ directory. I have also changed the permission of files under /etc/ssh/ directory. Now when i am trying to execute
ssh username@remoteserverIP -vv
I am getting below logs.

我无权访问root用户。我也尝试过腻子。 Putty给出了以下错误。
服务器意外关闭网络连接

或许/etc/hosts.deny包含＆＃34; ALL:＆＃34;的条目或＆＃34; ssh:＆＃34;阻止你连接。
添加＆＃34; ssh: ALL＆＃34;或＆＃34; ssh: x.x.x.x＆＃34; （将x.x.x.x替换为您的IP）到/etc/hosts.allow可以解决此问题。
