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 -ytftp-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 basedservices: 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
[iyunv@rhel1 ~]#chkconfig --list | grep tftp tftp: on
4、启动服务Xinetd # /etc/init.d/xinetdstart
5、验证tftp是否启动成功并监听本地69端口 [iyunv@rhel1 ~]#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 -i192.168.1.201 put TFTPServ.CNT tftp -i192.168.1.201 get vm-tool.tar.gz
