ubuntu10.04中配置tftp，并修改配置文件
1、安装
sudo apt-get install tftp
sudo apt-get install xinetd
2、创建共享目录
sudo mkdir /tftpboot
3、把共享目录修改为最大权限
sudo chmod 777 tftpboot
4、修改配置文件（/etc/inetd.conf）
1、我们看下我们默认的配置文件，配置文件如下
# /etc/inetd.conf: see inetd(8) for further informations.
#
# Internet superserver configuration database
#
#
# Lines starting with "#:LABEL:" or "#<off>#" should not
# be changed unless you know what you are doing!
#
# If you want to disable an entry so it isn't touched during
# package updates just comment it out with a single '#' character.
#
# Packages should modify this file by using update-inetd(8)
#
# <service_name> <sock_type> <proto> <flags> <user> <server_path> <args>
#
#:INTERNAL: Internal services
#discard stream tcp nowait root internal
#discard dgram udp wait root internal
#daytime stream tcp nowait root internal
#time stream tcp nowait root internal
#:STANDARD: These are standard services.
#:BSD: Shell, login, exec and talk are BSD protocols.
#:MAIL: Mail, news and uucp services.
#:INFO: Info services
#:BOOT: TFTP service is provided primarily for booting. Most sites
# run this only on machines acting as "boot servers."
tftp dgram udp wait nobody /usr/sbin/tcpd /usr/sbin/in.tftpd /srv/tftp
#:RPC: RPC based services
#:HAM-RADIO: amateur-radio services
#:OTHER: Other services
2、修改配置文件内容（添加我们刚才新建的共享工作文件夹）
把该行 tftp dgram udp wait nobody /usr/sbin/tcpd /usr/sbin/in.tftpd /srv/tftp
改为 tftp dgram udp wait nobody /usr/sbin/tcpd /usr/sbin/in.tftpd /tftpboot
5、启动tftp服务器
sudo /etc/init.d/xinetd restart
sudo in.tftpd -l /tftpboot
6、测试
1、在共享文件夹中新建一个文件
touch test.txt
2、启动tftp
tftp 192.168.0.148
说明，ip地址是自己的ip地址，查询方法，ifconfig
3、get test.txt
如果在当前文件夹看到test.txt则设置成功，否则重新检查配置
