1.打开终端,输入如下命令安装:
sudo apt-get install xinetd telnetd
2.安装成功后，打开/etc/inetd.conf并加入以下一行
telnet stream tcp nowait telnetd /usr/sbin/tcpd /usr/sbin/in.telnetd
3.打开 /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.打开/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
}
注:有的版本没有telnet这个文件,我们可以自己创建一个相同的文件,把内容保存到里面就可以了,保存编码格式为UTF-8!
5.重启机器或重启网络服务sudo /etc/init.d/xinetd restart
6.使用TELNET客户端远程登录或超级终端登录,成功后会提示输入用户名和密码
输入正确后,便可登录和控制Ubuntu
