Tftp 的应用场合
1、交换机或路由器升级或备份
2、无盘工作站 存放boot loader
3、嵌入式开发时装载系统
4、大规模的服务安装布署
安装
1、# yum install xinetd
# yum install -y
tftp-server
2、检查是否开机启动
# chkconfig --list |
grep xinet
xinetd 0:off 1:off
2:off 3:on 4:on
5:on 6:off
xinetd based
services:
chargen-dgram: off
chargen-stream: off
cvs: off
daytime-dgram: off

discard-dgram: off
discard-stream: off
echo-dgram: off
echo-stream: off
rsync: off
tcpmux-server: off
time-dgram: off

3、配置
# vim
/etc/xinetd.d/tftp
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /var/lib/tftpboot
-c
文件存放目录 RHEL5的目录为 /tftp/boot 可自定义 -c 允许上传
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}
#
chkconfig tftp on
也可已直接通过命令将服务改为开机启动
[[email protected] ~]#
chkconfig --list | grep tftp
tftp: on
4、启动服务Xinetd
# /etc/init.d/xinetd
start
5、验证tftp是否启动成功并监听本地69端口
[[email protected] ~]#
netstat -anup | grep 69
udp 0
0 0.0.0.0:69
0.0.0.0:*
15763/xinetd
6、测试上传和下载
tftp -i
192.168.1.201 put TFTPServ.CNT
tftp -i
192.168.1.201 get vm-tool.tar.gz
