通过管理面板，我可以访问日志，我看到：

Mar  8 20:32:10 vmi11458 sshd[2334]: Set /proc/self/oom_adj to 0
Mar  8 20:32:10 vmi11458 sshd[2334]: refused connect from 82.xxx.xxx.xxx (82.xxx.xxx.xxx)

我已停止 DenyHosts 服务。但我仍然无法登录。我该如何解决这个问题？

答案1

通过停止 denyhosts 服务，您可以防止在 中创建新条目/etc/hosts.deny，但已存在的条目仍然存在。您需要手动从hosts.deny文件夹中删除 IP。为了防止该IP被再次添加，需要在文件中将其列入白名单allowed-hosts。

答案2

要调试此问题，请检查以下事项：

  1. .ssh请仔细检查您的目录的权限700和.ssh/authorized_keys文件的权限是否必须为600.

  2. 检查日志/var/secure/logs 以了解连接关闭的原因。
