配置ubuntu的telnet服务

配置ubuntu的telnet服务

 

1、安装xinetd 以及telnetd

 $ sudo apt-get install xinetd telnetd

2、配置文件  www.2cto.com  

A。 /etc/inetd.conf

 $ cat /etc/inetd.conf （如果存在就不需要了）

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

 

B. 修改/etc/xinetd.conf

 $ sudo gedit /etc/xinetd.conf

# 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(插入红色部分）

instances = 60

log_type = SYSLOG authpriv

log_on_success = HOST PID

log_on_failure = HOST

cps = 25 30

}

includedir /etc/xinetd.d

 

C。修改/etc/xinetd.d/telnet

$ sudo gedit /etc/xinetd.d/telnet

并加入以下内容：  www.2cto.com  

# 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；
