linux限制ssh远程控制访问ip方法

/etc/hosts.deny  内容如下：

#
# hosts.deny This file describes the names of the hosts which are
#  *not* allowed to use the local INET services, as decided
#  by the '/usr/sbin/tcpd' server.
#
# The portmap line is redundant, but it is left to remind you that
# the new secure portmap uses hosts.deny and hosts.allow.  In particular
# you should know that NFS uses portmap!
all:all  

/etc/hosts.allow   添加能够访问的ip

设置好后，要重新启动  
  #   /etc/rc.d/init.d/xinetd   restart  
  #   /etc/rc.d/init.d/network   restart
