Ubuntu Telnet 服务

1、在虚拟机安装完ubuntu(此时可能不具备安装软件的功能)

2、更新软件安装包:

  sudo apt-get update

  sudo apt-get upgrade

3、安装telnet服务:

  sudo apt-get install openbsd-inetd

  sudo apt-get install xinetd telnetd

4、修改配置文件:

  1)nano /etc/inetd.conf

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

  2)nano /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
instances = 60
log_type = SYSLOG authpriv
log_on_success = HOST PID
log_on_failure = HOST
cps = 25 30

}

includedir /etc/xinetd.d

3)nano /etc/xinetd.d/telnet

# 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、重启网络服务

  service xinetd restart

  如果未安装xinetd服务,先安装一下:sudo apt-get install xinetd
