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
