Simple and practical Ubuntu FTP setup

1) It is not difficult to install vsftpdUbuntu. Enter sudoapt-getinstallvsftpd and you will be prompted to use the CD. Just press Enter. After installation, an ftp directory is created under/home. At this time, you can try to access the ftp: // ip address. You can see an ftp space with blank content. By default, anonymous users can download files, but cannot write or upload files. 2) Set vsftpd. conf file. 1) install vsftpd.

It is not difficult to install software in Ubuntu. Enter:

sudo apt-get install vsftpd

You may be prompted to use the CD and press Enter.

After installation, an ftp directory is created under/home. At this time, you can try to access the ftp: // ip address. You can see an ftp space with blank content.

By default, anonymous users can download files, but cannot write or upload files.

2) set the vsftpd. conf file

Now, we need to make anonymous users inaccessible and enter the user password on linux before they can access the contents in their own directories.

First, find the file for setting vsftpd, which is located in/etc/vsftpd. conf.

Back up this file before modification:

sudo cp /etc/vsftpd.conf /etc/vsftpd.conf.old

Then you can change the settings:

# Do not allow anonymous users to use
# Anonymous_enable = YES

# Available local users
Local_enable = YES

# Available write operations
Write_enable = YES

# File information in a directory is not required
# Dirmessage_enable = YES

# Add a banner prompt
Ftpd_banner = Hello ~~

# Maximum number of users on the FTP server
Max_clients = 100

# Restrict processes of each IP Address
Max_per_ip = 5

# Maximum transmission rate (B/s)
Local_max_rate = 256000

# Hiding accounts
Hide_ids = YES

Okay. Restart the ftp server to check the effect.

Is it the same after restart as before? Haha, This is the default ftp directory. Let's delete it and check again. How is it? Enter the user name and password.

New Problems

1. After Entering the username and password, the user's root directory is displayed, and our WEB content is in the public_html directory.

2. You can jump to any other directory (very dangerous ..)

To solve these problems, we have to set vsftpd. conf.

# Start the chroot list (Change root)
Chroot_list_enable = YES

# Specify the location of the List (I use the default address)
Chroot_list_file =/etc/vsftpd. chroot_list

Next, we need to write it in vsftpd. chroot_list. We want to restrict users so that they will not "drift "..

Currently, linyupark is a user, so you only need to write sudo nano to it.

In this way, we have solved 2nd problems. login users can only activity in their user folders. Below we want to be more aggressive, so that they can only activity in public_html.

Still find vsftpd. conf

# This statement is not set by default. Add it by yourself.
User_config_dir =/etc/define a folder address for individual users.

Create a folder Based on the address you set, and then create a file with the same username as the folder. nano:

# Root address of the local user. Assume that the user is linyupark.
Local_root =/home/linyupark/public_html

Okay. Restart the server. Check the effect. ^_^
