1、安装xinetd 以及telnetd

  $ sudo apt-get install xinetd telnetd

  2、配置文件

  A. /etc/inetd.conf

  $ cat /etc/inetd.conf (如果存在就不需要了)

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

  B. 修改/etc/xinetd.conf

  $ sudo gedit /etc/xinetd.conf

  # 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(插入红色部分)

  instances = 60

  log_type = SYSLOG authpriv

  log_on_success = HOST PID

  log_on_failure = HOST

  cps = 25 30

  }

  includedir /etc/xinetd.d

  C.修改/etc/xinetd.d/telnet

  $ sudo gedit /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

  6. 使用TELNET客户端远程登录;ifconfig -a显示本机地址;
