sshd_config中的DenyUsers选项不起作用,急!

yry6649324

我在/etc/ssh/sshd_config中添加
DenyUsers 8888
然后后启ssh,可8888用户还是能用ssh登录.这是为什么?
系统为SLES 9

DenyUsers username

这个语法是正确的

重启sshd服务了吗？

marsaber

重启sshd之后，8888是不能通过ssh连接到linux，但是可以本地登录。

现在的问题就是重启了ssh后,8888还是能通过ssh远程连到linux上.
sshd_config文件只有一个,而且更改了permitrootlogin yes,再重启ssh,证明sshd用的就是这个配置文件.
今天搞了一天也找不到原因.

用sshd -t也测试过了,配置文件没有错误.

你所建立的用户名是特殊用户名，你看一下8888用户的UID就知道了，很多配置文件是认UID的
建议不要建立纯数字用户名

谢谢scofield凌晨4点钟还回贴.
声明一下,8888只是随便乱输的,只是表示是一个用户.再加上SUSE上不允许用纯数字来做用户名.
而且sshd_config的man page里说必须要用用户名,不能用用户ID.以下是sshd_config的全部配置:

有没有可能是pam的问题?

DenyUsers s8888

试试
DenyUser s8888
