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)

我已经停止了 DenyHosts 服务。但是我还是无法登录，请问怎么解决？

Answer 1

通过停止拒绝主机服务，您可以防止在 中创建新条目/etc/hosts.deny，但已经存在的条目会保留。您需要从hosts.deny文件夹中手动删除 IP 。为防止再次添加该IP，您需要将其列入allowed-hosts文件中的白名单。
