ubuntu開啓telnet服務

 1.

sudo apt-get install xinetd telnetd


2. 安裝成功後,系統也會有相應提示(好象7.10纔有,6.10就沒看到)

  

sudo vi /etc/inetd.conf


並加入以下一行

  

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


(找不到文件忽略本步驟)

3.

sudo vi /etc/xinetd.conf


並加入以下內容:


  

# 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


並加入以下內容:

  

# 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. 重啓機器或重啓網絡服務

sudo /etc/init.d/xinetd restart


6. 使用TELNET客戶端遠程登錄;
