本文介绍如何配置 CentOS 的 SSH 服务以实现从指定 IP 范围内的主机进行远程登录。主要包括编辑 hosts.deny 和 hosts.allow 文件来限制访问来源，并重启 SSH 服务使配置生效。

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。^_^
