1.按照telnet
sudo apt-get install xinetd telnetd
2. 安装成功后,系统也会有相应提示,我的提示什么apt-get update不理
sudo vi /etc/inetd.conf并加入以下一行
telnet stream tcp nowait telnetd /usr/sbin/tcpd /usr/sbin/in.telnetd
(我的装完,发现这个文件已经在了,而且就是如上内容)
3. sudo vi /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
(我的这个文件也有)
4. sudo vi /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
}
(这个我的没有,是新建的文件,然后写进去保存的)
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
