在VMware安装一个CentOS的Sever版，终端里的内容不可滚动，不方便。在win下远程登录不错（win下有个Xshell）。默认安装SSH是有的。只是hosts访问问题。

　　1.在hosts.deny文件尾添加SSHd:ALL

　　意思是拒绝所有访问请求

　　[root@localhost ~]# vi /etc/hosts.deny

　　修改后看起来如下：

　　#

　　# 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!

　　SSHd:ALL

　　2.在hosts.allow文件尾添加SSHd:192.168.0.

　　意思是允许192.168.0.1 到254的主机，内网。

　　[root@localhost ~]# vi /etc/hosts.allow

　　#

　　# hosts.allow This file describes the names of the hosts which are

　　# allowed to use the local INET services, as decided

　　# by the '/usr/sbin/tcpd' server.

　　#

　　SSHd:192.168.0.

　　3.重启SSH

　　[root@localhost ~]# /etc/rc.d/init.d/SSHd restart

　　停止 SSHd： [ 确定 ]

　　启动 SSHd [ 确定 ]

　　好了，用putty和Xshell(Xmanager)可以登录了。
