linux ip白名单

linux ip白名单

配置文件:/etc/hosts.allow 

内容如下:

#

# hosts.allow   This file contains access rules which are used to

#               allow or deny connections to network services that

#               either use the tcp_wrappers library or that have been

#               started through a tcp_wrappers-enabled xinetd.

#

#               See 'man 5 hosts_options' and 'man 5 hosts_access'

#               for information on rule syntax.

#               See 'man tcpd' for information on tcp_wrappers

#

sshd:210.192.100.

注意:ip后面不能缺少句点

为什么要配置/etc/hosts.allow

因为刚才我在公司登陆阿里云时老是登陆不了,我估计被自己给禁了,所以使用手机热点登陆

看到了登陆拒绝的信息:

编辑/var/log/secure

 

把被拒绝的ip加到白名单(/etc/hosts.allow )就ok了
