刚安装的Ubuntu 12.04还没有telnet功能，需要配置一下。我主要是想让Ubuntu 12.04开启telnet服务做服务器。
安装openbsd-inetd:#sudo apt-get install openbsd-inetd
安装telnetd:#sudo apt-get install telnetd
在etc/inetd.conf文件中可以看到这一行内容：telnet stream tcp nowait root /usr/sbin/tcpd /usr/sbin/in.telnetd如果没有这一行内容，就手动加上
重启openbsd-inetd#/etc/init.d/openbsd-inetd restart
查看telnet运行状态#netstat -a | grep telnet输出： tcp 0 0 *:telnet *:* LISTEN
在windows的命令行中输入：telnet 192.168.1.8（我的linux的IP地址）按照提示输入用户名和密码进入（非root用户）
效果如下：
