This article mainly talks about "the construction and use of tftp server under Ubuntu system". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Next let the editor to take you to learn "the construction and use of tftp server under Ubuntu system"!

The simplest installation and configuration of tftp server

1. Install tftp-server

Sudo apt-get install tftpd-hpa

Sudo apt-get install tftp-hpa (you don't have to install the client if you don't need it)

Tftp-hpa is the client

Tftpd-hpa is the server side

two。 Configure the TFTP server

Sudo vim / etc/default/tftpd-hpa

Change the original content to:

TFTP_USERNAME= "tftp"

TFTP_ADDRESS= "0.0.0.0Vol 69"

TFTP_DIRECTORY= "tftp Root Directory" # server directory, you need to set the permission to 777PowerChomd 777

TFTP_OPTIONS= "- l-c-s"

3. Restart the TFTP service

Sudo service tftpd-hpa restart

4. Check whether the tftp service is enabled

Netstat-a | grep tftp

The display result is

Udp 0 0 *: tftp *: *

Indicates that the service has been turned on, which means that the tftp configuration is successful.

Parameter description:

-l is an abbreviation for local, followed by the name of the source file that exists in Client, or the file name that is renamed after downloading Client.

-r is the abbreviation of remote, followed by Server, the source file name in the root directory of the tftp server on PC, or the file name renamed after uploading Server.

-g is an acronym for get, used when downloading files

-p is an acronym for put, used when uploading files

Tftp occupies port 69 by default.

Based on the above parameters, the command format for tftp is as follows

1. Tftp-GPUP destination filename source filename server address

-GCPUP

Target file name

Source file name

Server address

Description

-g means download

-p means upload

Can be the same or different from the source file name

Add the parameter-l when downloading

Add the parameter-r when uploading

Cannot be renamed

Add the parameter-r when downloading

Add the parameter-l when uploading

As can be seen from the description of the above table

When downloading files from Server to Client, use the following command:

Tftp-g-l destination file name-r source file name server address

As ordered

Tftp-g-l B.txt-r A.txt 192.168.1.2

The function is to download the file A.txt to Client from the tftp root directory in server and rename it B.txt; if you don't change the name, B.txt will be changed to A.txt.

When uploading files from Clinet to Server, use the following command

Tftp-p-r destination file name-l source file name server address

As ordered

Tftp-p-r D.txt-l C.txt 192.168.1.2

The function is to upload the file C.txt from Client to the tftp root target of Server, and rename it to D.txt; if you don't change the name, D.txt will be changed to C.txt.

This command is generally used to change the file name after download or upload. If you do not change the file name, you can use the following simple command

2. Download or upload without changing the name

Download command without renaming:

Tftp-g-lUnigram source filename server address

(in this case, the parameter-l is equivalent to-r, and only one of them is used.)

Such as tftp-g-l A.txt 192.168.1.2 or tftp-g-r A.txt 192.168.1.2

The same effect means that Client downloads the file A.txt from Server and does not change its name.

Tftp-p-lUnigram source filename server address

(in this case, the parameter-l is equivalent to-r, and only one of them is used.)

Such as tftp-p-l B.txt 192.168.1.2 or tftp-p-r B.txt 192.168.1.2

The same function, all means to upload files from Client B.txt to Server, and do not change the name.
