1、首先以root权限运行apt-get install xinetd,普通用户的执行命令是sudo apt-get install xinetd
2、接着运行以root权限apt-get install telnet,普通用户的执行命令是sudo apt-get install telnet
3、新建telnet文件，并将其拷到/etc/xinetd.d目录下，telnet文件内容如下：service telnet{disabl髫潋啜缅e = noflags = REUSEsocket_type = streamwait =nouser = rootserver = /usr/sbin/in.telnetdlog_on_failure += USERID}
4、 新建垓矗梅吒xinetd.conf文件，并将其拷到/etc目录下，xinetd.conf文件内容如下：# Simple configuration 熠硒勘唏file for xinetd## Some defaults, and include /etc/xinetd.d/defaults{# Please note that you need a log_type line to be able to use log_on_success# and log_on_failure. The default is the following :# log_type = SYSLOG daemon infoinstance = 60log_type = SYSLOG authprivlog_on_success = HOST PIDlog_on_failure = HOSTcps = 25 30}includedir /etc/xinetd.d
5、运行/etc/init.d/xinetd restart(root权限)sudo /etc/init.d/xinetd restart(一般用户)，重启服务
6、运行netstat -a 可以看到telnet服务已开启
