ubuntu配置telnet服务

1、安装xinetd 以及telnetd

#:~$ sudo apt-get install xinetd telnetd

2、配置文件（若文件不存在就手动添加文件和相应配置信息）

1): #:~$ vi /etc/inetd.conf 添加下面一行信息

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

2): #:~$ vi /etc/xinetd.conf 修改下面红色标注部分的信息

# 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

3): #:~$ vi /etc/xinetd.d/telnet 修改下面红色标注部分的信息

# 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

}

3. 重启机器或重启网络服务

#:~$ /etc/init.d/xinetd restart
