【问题描述】：

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。我也试过通过腻子。腻子给出以下错误。

服务器意外关闭网络连接

【问题讨论】：

这和java有什么关系？
我删除了标签 JAVA
Stackoverflow 用于软件开发方面的帮助。您应该考虑在Unix & Linux、Server Fault 或Super User 上而不是在这里提出这样的问题。此外，“ssh_exchange_identification: read: Connection reset by peer”是一个很常见的错误消息。您应该能够搜索它并找到其他问题。

标签： linux ssh centos

【解决方案1】：

也许/etc/hosts.deny 包含一个“ALL:”或“ssh:”条目阻止您连接。

将“ssh: ALL”或“ssh: x.x.x.x”（将 x.x.x.x 替换为您的 IP）添加到 /etc/hosts.allow 可以解决此问题。
