This article mainly introduces "the method of building and starting the FTP server and the configuration of the client". In the daily operation, I believe that many people have doubts about the construction and startup of the FTP server and the configuration of the client. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful for you to answer the doubts about the construction and startup of the FTP server as well as the configuration of the client. Next, please follow the editor to study!

Install the TFTP server

The first thing you need to do is install the TFTP client and TFTP server:

Dnf install tftp-server tftp- y

The above command creates tftp.service and tftp.socket files for systemd in the / usr/lib/systemd/system directory.

/ usr/lib/systemd/system/tftp.service / usr/lib/systemd/system/tftp.socket

Next, copy the two files to the / etc/systemd/system directory and rename them.

Cp / usr/lib/systemd/system/tftp.service / etc/systemd/system/tftp-server.service cp / usr/lib/systemd/system/tftp.socket / etc/systemd/system/tftp-server.socket

Modify a file

When you copy and rename these files, you can add some extra parameters. Here's what tftp-server.service looks like at first:

[Unit] Description=Tftp Server Requires=tftp.socket Documentation=man:in.tftpd [Service] ExecStart=/usr/sbin/in.tftpd-s / var/lib/tftpboot StandardInput=socket [Install] Also=tftp.socket

Add the following in the [Unit] section:

Requires=tftp-server.socket

Modify the [ExecStart] line:

ExecStart=/usr/sbin/in.tftpd-c-p-s / var/lib/tftpboot

Here are what these options mean:

The-c option allows you to create a new file

The-p option indicates that there is no additional permission check on top of the permission check provided by the normal system

-s recommends using this option to ensure security and compatibility with certain boot ROM that do not easily include directory names in their requests.

The default upload and download locations are located at / var/lib/tftpboot.

Next, modify the contents of the [Install] section

[Install] WantedBy=multi-user.target Also=tftp-server.socket

Don't forget to save your changes.

Here is the complete content of the / etc/systemd/system/tftp-server.service file:

[Unit] Description=Tftp Server Requires=tftp-server.socket Documentation=man:in.tftpd [Service] ExecStart=/usr/sbin/in.tftpd-c-pmurs / var/lib/tftpboot StandardInput=socket [Install] WantedBy=multi-user.target Also=tftp-server.socket

Start the TFTP server

Restart the systemd daemon:

Systemctl daemon-reload

Start the server:

Systemctl enable-now tftp-server

To change the permissions that the TFTP server allows to upload and download, use this command. Note that TFTP is an inherently insecure protocol, so it is not recommended that you do so on a network that is shared with others.

Chmod 777 / var/lib/tftpboot

Configure the firewall to enable TFTP to use:

Firewall-cmd-add-service=tftp-perm firewall-cmd-reload

Client configuration

Install the TFTP client

Yum install tftp-y

Run the tftp command to connect to the server. The following is an example of enabling the details option:

[client@thinclient:~] $tftp 192.168.1.164 tftp > verbose Verbose mode on. Tftp > get server.logs getting from 192.168.1.164:server.logs to server.logs [netascii] Received 7 bytes in 0.0 seconds [inf bits/sec] tftp > quit [client@thinclient:~] $

Remember, because TFTP does not have the ability to list files on the server, you need to know the specific name of the file before you use the get command.

At this point, the study on "how to build and start the FTP server and the configuration of the client" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
