Configuring ‘vsftpd’

We needed to edit the configuration file ‘vsftpd’ for securing the FTP server since, by default it will allow anonymous users to login and use the server.

# vi /etc/vsftpd/vsftpd.conf

We have to disallow anonymous, unidentified users to access files via FTP; change the anonymous_enable setting to NO:

anonymous_enable=NO

Allow local users to login by changing the local_enable setting to YES:

local_enable=YES

If you want to allow the local users to be able to write to a directory, then change the write_enable setting in the configuration file to YES:

write_enable=YES

Local users will be ‘chroot jailed’ and they will be denied access the local users to any other part of the server; change the chroot_local_user setting in the configuration file to YES:

chroot_local_user=YES

Below is the simple configuration file for your reference –

anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022
chroot_local_user=YES
dirmessage_enable=YES
xferlog_enable=YES
connect_from_port_20=YES
xferlog_std_format=YES
listen=YES
#listen_ipv6=YES
pam_service_name=vsftpd
userlist_enable=YES
tcp_wrappers=YES
Save the file with the command :wq .

Restarting the vsftpd Service

We needed to restart the ‘vsftpd’ services so that the configuration changes has applied

# systemctl restart vsftpd

We will set the ‘vsftpd’ service to start at boot time, below is the command to enable the ‘vsftpd’ to start.

# systemctl enable vsftpd

Allowing the ‘vsftpd’ Through the Firewall

We have to allow the default FTP port, port 21, through firewall.

# firewall-cmd --permanent --add-port=21/tcp

We needed to reload the firewall so that the firewall.

# firewall-cmd –reload

Create the FTP user’s

We will create FTP user other than local users and assign the home directory

For this tutorial, I will create a user without a home directory therefore I use –M instead of –m.

# useradd -M user1 –s /sbin/nologin
# passwd user1

We will next set the home directory for “user1” by creating a new directory

# mkdir /var/www/mike
# chmod 755 /var/www/mike

We have to provide access to the “user1” on FTP

# chown -R mike /var/www/user1
We can access the FTP server from the client on your favorite browser using the url ftp://192.168.100.108

By using the above information, we can easily configure and install the FTP server. ‘vsftpd’ is a simple and very secure FTP server, we can use local user and we can also create other users specially to use FTP ‘vsftpd’ server which has many more features too.
