1. 安装xinetd和telnetd
 1  sudo apt-get install xinetd telnetd 
1. /etc/inetd.conf在安装过程中已经配置好，修改/etc/xinetd.conf
  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16  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 ## 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 # ## start the insert content # # if I have time, I will add some comments about this part. # instances =60#log_type = SYSLOG authpriv # log_on_success = HOST PID # log_on_failure = HOST # tcps = 25 30 ## end the insert content 
1. 添加/etc/xinet.d/telnet
  1 2 3 4 5 6 7 8 9 10  #service telnet #{ #disable = no #flags = REUSE #socket_type = stream #wait = no #user = root #server = /usr/sbin/in.telnetd #log_on_failure += USERID #}
