1. sudo apt-get install xinetd telnetd 
    2.安装成功后,系统也会有相应提示(好象7.10才有,6.10就没看到)
    sudo vi /etc/inetd.conf 并加入以下一行
    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
    6.使用TELNET客户端远程登录;ifconfig -a 显示本机地址
