linux限制ssh遠程控制訪(fǎng)問(wèn)ip方法

/etc/hosts.deny  內容如下：

#
# 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   添加能夠訪(fǎng)問(wèn)的ip

設置好后，要重新啟動(dòng)  
  #   /etc/rc.d/init.d/xinetd   restart  
  #   /etc/rc.d/init.d/network   restart
