AllowUsers ec2-user root AllowUsers root@1.2.3.0/24AllowUsers ec2-user@1.1.1.1root@1.2.3.* 说明: 这样配置后,在ssh登录时,linux系统sshd服务会对登录者进行检查,只有在AllowUsers列表中的才被允许登录 那么同理:如果对于AllowGroups的配置,就是配置允许的groups了,多个group之间也是使用空格隔开 但笔者测试发现,...
1.限制性SSH访问,将sshd绑定到一个ip地址,和允许所有ip地址是完全不同的安全。 2.将sshd默认端口22改为其它端口。 步骤如下: 前提: SSH 客户端 - 我推荐使用 putty (搜索google,你会很快找到它) SSH 服务已安装 第一步: 以root身份SSH登录到服务器。 第二步:在命令提示符下输入:pico -w /etc/ssh/ssh...

比如: 1.禁止所有ip访问linux 的ssh功能 可以在/etc/hosts.deny添加一行 sshd:all:deny 2.禁止某一个ip(192.168.11.112)访问ssh功能 可以在/etc/hosts.deny添加一行sshd:192.168.11.112 3.如果在/etc/hosts.deny和/etc/hosts.allow同时 有sshd:192.168.11.112 规则,则192.168.11.112可以访问主机的ssh服务 总结:...
