To set up an FTP server in Ubuntu, install the vsftpd package using the apt-get command. Edit the vsftpd configuration file to enable anonymous access and file writes by uncommenting the appropriate lines. Restart the vsftpd service to launch the FTP server.

1. How to Set up FTP Server in Ubuntu
Steps
1. Boot up Ubuntu Linux.
2. Go to Application, then select Accessories and chose Terminal

2. 3. Enter the following command: “sudo apt-get install vsftpd” (without quotation
marks). This will install the FTP server on your system. If you are logged in as the
root user, the "sudo" command will not be necessary, since this command is used to
give administrative privileges to the user. In this case, you will only need the
command "apt-get install vsftpd".
4. Open the FTP server configuration file. To do so, go to Places and click on
Computer.

3. 5. In the file browser, click the “File System” icon.
6. Click on the “etc” folder.

4. 7. Double-click the “vsftpd.conf” icon.
8. Alter anonymous access. Enter "anonymous_enable=YES" (without quotation
marks) to allow anonymous FTP access. The hash (#) at the beginning of each line
indicates that this line is commented out and will be ignored. To enable this line, you
must remove the hash (#). The parameter "write_enable=YES" (without quotation
marks) will allow changes to the filesystem, such as uploading.

5. 9. Rename the FTP welcome banner. Uncomment it by removing the hash (#), and
enter the welcome message. For this example it's "ftpd_banner=Welcome to FTP
Server!" (without quotation marks).
10. Click on Save and close the file. (Note: You may need to login as root, then only you
will be able to open file in edit mode or else the file will open in read-only mode)

6. 11. To restart the FTP service, type the following command: “sudo /etc/init.d/vsftpd
restart” (without quotation marks). Again, you will only need to use "sudo" if you are
no logged as the root user.
12. Place files on the FTP server. To move files to the server, access the FTP Folder
from the command in the image below.
