转自： http://blog.csdn.net/ruglcc/article/details/7804377

1. sudo apt-get install xinetd telnetd

sudo vi /etc/inetd.conf

并加入以下一行，假如没有发现这个文件，自己新建立一个也是可以的哦，刚开始我也不知道，自己试了之后才知道的。

telnet stream tcp nowait telnetd /usr/sbin/tcpd /usr/sbin/in.telnetd

3. sudo vi /etc/xinetd.conf

并加入以下内容：

# Simple configuration 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 info

instances = 60
log_type = SYSLOG authpriv
log_on_success = HOST PID
log_on_failure = HOST
cps = 25 30
}

includedir /etc/xinetd.d

4. sudo vi /etc/xinetd.d/telnet并加入以下内容：

# default: on
# description: The telnet server serves telnet sessions; it uses \
# unencrypted username/password pairs for authentication.
service telnet
{
disable = no
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/sbin/in.telnetd
log_on_failure += USERID
}

 

5. 重启机器或重启网络服务

sudo /etc/init.d/xinetd restart
