ubuntu14.04中安装telnet客户端 （亲测）

一、首先查看telnet运行状态

#netstat -a | grep telnet

     输出为空，表示没有开启该服务

二、安装openbsd-inetd 和 telnetd

apt-get install openbsd-inetdapt-get install telnetd

三、sudo vi /etc/inetd.conf 并加入以下一行

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

四、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 uselog_on_success# and log_on_failure. The default is the following :# log_type = SYSLOG daemon infoinstances = 60log_type = SYSLOG authprivlog_on_success = HOST PIDlog_on_failure = HOSTcps = 25 30}includedir /etc/xinetd.d

五、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 = noflags = REUSEsocket_type = streamwait = no  www.2cto.com  user = rootserver = /usr/sbin/in.telnetdlog_on_failure += USERID}

六、重启ubuntu 即可。
