Ubuntu 12.04 Telnet服务设置

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:
