Ubuntu如何配置Telnet服务器

一、安装Telnet Server

1)下载xinetd_2.3.15-1ubuntu2_amd64.deb、telnetd_0.17-36build2_amd64.deb

2)安装Telnet

sudo dpkg –i telnetd_0.17-36build2_amd64.deb

sudo dpkg –i telnetd_0.17-36build2_amd64.deb

如果连网时，可以通过sudo apt-get install telnetd

3)设置ip

终端中输入：sudo ifconfig eth0 192.168.0.120 netmask 255.255.255.0

4)修改/etc/xinetd.conf配置文件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

# 红色表示插入的部分

instances = 60

log_type = SYSLOG authpriv

log_on_success = HOST PID

log_on_failure = HOST

cps = 25 30

}

5)修改/etc/xinetd.d/telnet配置文件

加入如下内容：

# default: on

# description: The telnet server serves telnet sessions; it users

# 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

}

6) 重启网络服务

sudo /etc/init.d/xinetd restart

sudo service xinetd restart

至此telnet服务配置完成

二、测试

Win7客户端必须启动Telnet客户端服务，然后在命令行输入telnet后，提示输入用户名和密码即为配置成功
