Ubuntu中配置tftp,烧写内核用

1、安装相关软件包
sudo apt-get install tftpd （服务端）
sudo apt-get install tftp （客户端）
sudo apt-get install xinetd

2、建立配置文件
cd /etc/xinetd.d/
sudo vim tftp
输入
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /tftpboot
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}

存盘退出

3、建立tftp服务文件目录
sudo mkdir /tftpboot
sudo chmod 777 /tftpboot -R

4、从新启动服务
sudo /etc/init.d/xinetd restart
安装完成！

测试：
/nfsroot/rootfs/button$ tftp 192.168.2.75
tftp> put hello.c
Sent 1018 bytes in 0.0 seconds
tftp> get hello.c
Received 1018 bytes in 0.1 seconds
tftp> put book.c
Sent 1980 bytes in 0.0 seconds
tftp> get book.c
Received 1980 bytes in 0.0 seconds

注： nfsroot/rootfs/button预先有hello.c book.c
