在ubuntu下安装xinetd模式的tftpd服务

1、安装server与client
sudo apt-get install tftpd-hpa tftp-hpa

2、删除standalone的启动方式
update-rc.d -f tftpd-hpa remove

3、新建用户tftpd及其主目录
sudo mkdir -p /home/tftpd
sudo useradd -s /bin/false -g nogroup -d /home/tftpd [-p PASSWORD] tftpd

4、新建xinetd启动文件
cat /etc/xinetd.d/tftpd
service tftp
{
disable = no
socket_type = dgram
wait = no
user = root
protocol = udp
server = /usr/sbin/in.tftpd
server_args = -s /home/tftpd -p -c -U 077 -u tftpd
log_on_success += PID HOST DURATION
log_on_failure += HOST
}
5、注释掉/etc/inetd.conf文件中tftpd启动
#tftp dgram udp wait root /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /var/lib/tftpboot

6、重新启动xinetd服务
sudo /etc/init.d/xinetd restart

7、测试tftpd服务是否成功
tftp localhost
tftp> put 123.log
tftp> put 123.log test.log
tftp> get test.log
tftp> get test.log abc.log
tftp> verbose
Verbose mode on.
tftp> trace

tftp> put kkk.log

.........
