Setup of VSFTPD virtual users

If you are hosting several web sites, for security reason, you may want the webmasters to access their own files only. One of the good way is to give them FTP access by setup of VSFTPD virtual users and directories. This article describes how you can do that easily.

1. Installation of VSFTPD

For Red Hat, CentOS and Fedora, you may install VSFTPD by the command

# yum install vsftpd

For Debian and Ubuntu,

# apt-get install vsftpd

2. Virtual users and authentication

We are going to use pam_userdb to authenticate the virtual users. This needs a username / password file in `db’ format – a common database format. We need `db_load’ program. For CentOS, Fedora, you may install the package `db4-utils’:

# yum install db4-utils

For Ubuntu,

# apt-get install db4.2-util

To create a `db’ format file, first create a plain text file `virtual-users.txt’ with the usernames and passwords on alternating lines:

mary
123456
jack
654321

Then execute the following command to create the actual database:

# db_load -T -t hash -f virtual-users.txt /etc/vsftpd/virtual-users.db

Now, create a PAM file /etc/pam.d/vsftpd-virtual which uses your database:

auth required pam_userdb.so db=/etc/vsftpd/virtual-users
account required pam_userdb.so db=/etc/vsftpd/virtual-users

3. Configuration of VSFTPD

Create a configuration file /etc/vsftpd/vsftpd-virtual.conf,

# disables anonymous FTP
anonymous_enable=NO
# enables non-anonymous FTP
local_enable=YES
# activates virtual users
guest_enable=YES
# virtual users to use local privs, not anon privs
virtual_use_local_privs=YES
# enables uploads and new directories
write_enable=YES
# the PAM file used by authentication of virtual uses
pam_service_name=vsftpd-virtual
# in conjunction with 'local_root',
# specifies a home directory for each virtual user
user_sub_token=$USER
local_root=/var/www/virtual/$USER
# the virtual user is restricted to the virtual FTP area
chroot_local_user=YES
# hides the FTP server user IDs and just display "ftp" in directory listings
hide_ids=YES
# runs vsftpd in standalone mode
listen=YES
# listens on this port for incoming FTP connections
listen_port=60021
# the minimum port to allocate for PASV style data connections
pasv_min_port=62222
# the maximum port to allocate for PASV style data connections
pasv_max_port=63333
# controls whether PORT style data connections use port 20 (ftp-data)
connect_from_port_20=YES
# the umask for file creation
local_umask=022

4. Creation of home directories

Create each user’s home directory in /var/www/virtual, and change the owner of the directory to the user `ftp’:

# mkdir /var/www/virtual/mary
# chown ftp:ftp /var/www/virtual/mary

5. Startup of VSFTPD and test
Now we can start VSFTPD by the command:

# /usr/sbin/vsftpd /etc/vsftpd/vsftpd-virtual.conf

and test the FTP access of a virtual user:

# lftp -u mary -p 60021 192.168.1.101

The virtual user should have full access to his directory.

    Great tutorial, but if the ftp server is up and running, how can I add and delete users?

  2. coolmig Says:

    This is fair easy:

    1. Redo some things of step 2:

    Update the plain text file `virtual-users.txt’ you did before with the usernames and passwords on alternating lines:

    mary
    123456
    jack
    654321
    mynewuser
    162534

    Then execute again the following command to create the actual database:

    # db_load -T -t hash -f virtual-users.txt /etc/vsftpd/virtual-users.db

    Redo the step 4 for the new user folder:

    # mkdir /var/www/virtual/mynewuser
    # chown ftp:ftp /var/www/virtual/mynewuser

    That’ll do.

    Great howto! Useful for a standalone set up but where can find one where I can set up virtual users and regular accounts all running on port 21? Meaning those with shell access and those without shell access can both use an ftp client on port 21.

    I use pair networks and I have ftp access for my shell account and can set up virtual ftp accounts all on port 21.

  4. babola Says:

    I’d like to know the same thing… How do I set up vsftpd so that regular users (those in /etc/passwd) AND virtual users have access? Thx, B.

  5. oscar Says:

    Excellent. Did it in 20 min. with ssl !!!!
    Easier than I thought

  6. dsc Says:

    How to I reset all pertinent config files resulting from previous attempts with other tutorials, in order to try a “pure” version of this one? I’m using centos. I’m not really hopeful that it would really make a difference, as this tutorial sets its own configuration files, so it shouldn’t be an issue, I guess. But anyway, if anyone knows about some easier way to do that (get rid of configuration files that may be conflicting), I’d like a lot to know. Thanks.

    I get this on debian lenny, when I run “db_load -T -t hash -f vsftpd_users.txt /etc/vsftpd/virtual-users.db”:

    bash: db_load: command not found

    ????

  8. jack Says:

    yeah im getting same error as jacob

    bash: db_load: command not found ??? any ideas im using ubuntu hardy

  9. jack Says:

    doesn’t matter i fixed it via using the following command

    db4.2_load -T -t hash -f virtual-users.txt /etc/vsftpd/virtual-users.db

    Is there anyway to have domain centric authentication ?
    So domains example1.com and example2.com will have different users ?

  15. LHIX Says:

    I have followed these instructions Steps 1 through 4. When I try step 5, I get “500 OOPS: missing value in config file for: for each virtual user”. I’m using CentOS 5.6. I have removed vsftpd, rebooted and reinstalled. Again, I get the same message when trying to start vsftpd (Step 5). I copied the entire config text from Step 3 without making changes..

    Yes, I am a NOOB. Please Advise.

  16. sandajian Says:

    It seems your config file has some error, did you mis-delete the first ‘#’ in the first line beblow?

    # specifies a home directory for each virtual user
    user_sub_token=$USER
    local_root=/var/www/virtual/$USER

  17. LHIX Says:

    Found the issue – When I copied the configuration from Step 3, there was a return between “specifies a home directory” and “for each virtual user”.

    Also, on Step 4, I found I needed to use the switch “-p” to create the directory.

    Thanks
