centos配置ssh

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。
