1、安装两个软件包:tftp、tftpd,tftp是客户端,tftpd是服务器;

2、创建根目录:sudo mkdir /srv/tftp,赋予权限,chmod a+w /srv/tftp;

3、查看配置文件/etc/inetd.conf:“tftp dgram udp wait nobody /usr/sbin/tcpd /usr/sbin/in.tftpd /srv/tftp”,最后的/srv/tftp是tftpd存放文件的路径

4、启动tftp服务:in.tftpd -l /srv/tftp;

5、测试tftp服务:

root@lion3875-laptop:# tftp localhost
tftp> ?
Commands may be abbreviated. Commands are:

rexmt set per-packet retransmission timeout

? print help information
tftp> put xx (将当前目录下的xx文件上传到tftp根目录/srv/tftp)

tftp> get xx(从tftp根目录/srv/tftp下载xx文件到当前目录)
