Tftp 的應用場合

1、交換機或路由器升級或備份

2、無盤工作站 存放boot loader

3、嵌入式開發時裝載系統

4、大規模的服務安裝布署

?

安裝

1、# yum install xinetd

????? # yum install -y tftp-server

2、檢查是否開機啟動

# 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

??????? daytime-stream: off

??????? discard-dgram:? off

??????? discard-stream: off

??????? echo-dgram:???? off

??????? echo-stream:??? off

??????? rsync:????????? off

??????? tcpmux-server:? off

??????? time-dgram:???? off

??????? time-stream:??? 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?

????? 文件存放目錄 RHEL5的目錄為 /tftp/boot? 可自定義 -c 允許上傳

?????? ?disable???????????????? = no

??????? per_source????????????? = 11

??????? cps???????????????????? = 100 2

??????? flags?????????????????? = IPv4

}

# chkconfig tftp on ??

? 也可已直接通過命令將服務改為開機啟動

?

[root@rhel1 ~]# chkconfig --list | grep tftp

??????? tftp:?????????? on

?

?

4、啟動服務Xinetd

# /etc/init.d/xinetd start

?

5、驗證tftp是否啟動成功并監聽本地69端口

[root@rhel1 ~]# netstat -anup | grep 69

udp??????? 0????? 0 0.0.0.0:69????????????????? 0.0.0.0:*?????????????????????????????? 15763/xinetd???????

?

6、測試上傳和下載

tftp -i 192.168.1.201 put TFTPServ.CNT

tftp -i 192.168.1.201 get vm-tool.tar.gz
