Three steps to build a tftp server

After learning about some basic content of the tftp server, we should begin to learn how to build the tftp server. Next, we will make a simple summary of this building process. I hope you can understand this part through the content of this article.

Set up a tftp server 1. Check whether the tftp server software is installed in the system:

[Root @ localhost lqm] # rpm-qa | grep tftp

Tftp-0.39-2

Tftp-server-0.39-2

Tftp server Construction 2. edit the file:/etc/xinetd. d/tftp

[Root @ localhost xinetd. d] # vi tftp

# Default: off

# Description: The tftp server serves files using the trivial file transfer \

# Protocol. The tftp protocol is often used to boot diskless \

# Workstations, download configuration files to network-aware printers ,\

# And to start the installation process for some operating systems.

Service tftp

{

Socket_type = dgram

Protocol = udp

Wait = yes

User = root

Server =/usr/sbin/in. tftpd

Server_args =-s/home/lqm/tftpboot-c

Disable = yes --------------- change yes to no!

Per_source = 11

CPIs = 100 2

Flags = IPv4

Note: The Modification Item server_args =-s-c can be changed to the root directory of your tftp-server, the parameter-s specifies chroot, and-c specifies that files can be created.

Build a tftp Server 3. Create a tftp folder

# Mkdir/home/lqm/tftpboot

# Chmod o + w/home/lqm/tftpboot

/Etc/init. d/iptables stop // disable the Firewall

Service xinetd restart // restart the xinetd service

Restart the xinetd service because the TFTP service is controlled by xinetd. xinetd is a service that manages services and does not open ports.

Verify whether TFTP is up:

[Root @ localhost tftp_root] # netstat-nlp

Active Internet connections (only servers)

Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name

Tcp 0 0: 22: * LISTEN 2828/sshd

Udp 0 0 0.0.0.0: 69 0.0.0.0: * 10887/xinetd

Udp 0 0 0.0.0.0: 69 0.0.0.0: * 10863/in. tftpd

Udp 0 0 0.0.0.0: 69 0.0.0.0: * 10778/in. tftpd

Port 69 is enabled, indicating that the service is started properly.

# Service xinetd restart

In this way, tftp-server is started. You can log on to the local machine to test the following command:

# Tftp your-ip-address

Tftp> get <download file>

Tftp> put <upload file>

Tftp> q
