Install using TFTP under Linux system

First, Description:

TFTP is the simplest network protocol for downloading remote files, which is implemented in the UDP protocol. The TFTP development environment of embedded Linux includes two aspects: one is Tftp-server support of Linux server side and the other is tftp-client support of embedded target system. Because the u-boot itself has built-in support for Tftp-client, the embedded target system is not configured.

XINETD (eXtended Internet Services daemon) is a new generation of network daemon services, also known as a Super Internet server, often used to manage a variety of lightweight InterNET services, XINETD provides a inetd+-like Tcp_wrapper features, but more powerful and secure.

Second, install the TFTP server:

Need to install XINETD, TFTP, tftp-server

1. If you can surf the Internet, install via Yum:

Yum-y Install xinetd

Yum-y Install TFTP

Yum-y Install Tptp-server

2. If the Internet is not available, the RPM package provided can be installed directly:

RPM-IVH xinetd-2.3.14-38.el6.src.rpm

RPM-IVH tftp-0.48-3.fc9.src.rpm

RPM-IVH tftp-server-0.48-3.fc9.i386.rpm

Note, installation package can be in my Baidu cloud, download link: Http://pan.baidu.com/s/1c2tOfKW

Third, configure the TFTP server:

(1), modify the/etc/xinetd.d/tftp file

disable=Yes change to disable=no

server_args=-s /var/lib/tftpboot   Change to   server_args=-s /tftpboot/-C

(2) Modify the/etc/sysconfig/selinux file

Selinux=disabled (system default is enforcing) to change to disabled

Note, this step requires a restart of the server to take effect

Can be temporarily shut down (no need to restart the machine)

Setenforce 0

(3), new Tftpboot directory, and Add permissions:

mkdir/tftpboot/

chmod 775/tftpboot

Four, start the TFTP server:

Service xinetd Restart

To see if the TFTP service is turned on:

netstat-a | grep tftp

The result is UDP 0 0 *:tftp *:* indicates that the service is enabled and the TFTP configuration is successful

V. Use of commands:

Copy the Test.tar file to the directory/tftpboot

To download files on the client:

Tftp-gr Test.tar 192.168.2.100

Note Frequently Asked Questions:

1.SELinux needs to be closed

2,/tftpboot directory needs to be new under the root, and give sufficient permissions to facilitate the client to download
