It is already installed at the time of openSUSE installation.
If not, you can install it with the following command

# zypper -n install vsftpd

1	# zypper -n install vsftpd

1.2 Edit vsftpd configuration file

Save the unedited vsftpd.conf with .bak.

# cp /etc/vsftpd.conf /home/suse/vsftpd.conf.bak

1	# cp /etc/vsftpd.conf /home/suse/vsftpd.conf.bak

# vi /etc/vsftpd.conf

Add users to allow directory access to upper level

#  echo "suse" >> /etc/vsftpd.chroot_list

1	# echo "suse" >> /etc/vsftpd.chroot_list

In my case I wrote suse.

Enable vsftpd autostart and start it

# systemctl enable vsftpd
Created symlink /etc/systemd/system/multi-user.target.wants/vsftpd.service → /usr/lib/systemd/system/vsftpd.service.

1 2	# systemctl enable vsftpd Created symlink /etc/systemd/system/multi-user.target.wants/vsftpd.service → /usr/lib/systemd/system/vsftpd.service.

# systemctl start vsftpd

1	# systemctl start vsftpd

1.3 firewall settings

FTP port open (FTP uses 21)

# firewall-cmd --add-service=ftp --permanent
# firewall-cmd --reload

1 2	# firewall-cmd --add-service=ftp --permanent # firewall-cmd --reload

From windows, check if you can connect with FileZilla
Start FileZilla and select "Site Manager" from the "File" menu.

"New site" click
Enter the following settings for each item and click "Connect"
Protocol : FTP - File Transfer Protocol
Host: server IP address
Port: (blank)
Encryption : Use explicit FTP over TLS if available
Logon Type: Ask for password
User : login user

Password : login user password

If the connection is successful, you will see the server directory on the right and the Windows directory on the left.

2. vsftpd SSL/TLS

Configure Vsftpd to use SSL/TLS

2.1 Create self-signed certificates

This work is not required if you are using a trusted, legitimate certificate such as Let's Encrypt.

# cd /etc/ssl/private

1	# cd /etc/ssl/private

/etc/ssl/private # openssl req -x509 -nodes -newkey rsa:2048 -keyout vsftpd.pem -out vsftpd.pem -days 365

Generating a 2048 bit RSA private key
............+++......+++
writing new private key to '/etc/pki/tls/certs/vsftpd.pem'
-----
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:JP&nbsp;&nbsp; <country code>
State or Province Name (full name) [Some-State]:Tokyo <Region (Prefecture)>
Locality Name (eg, city) []:Tama <City>
Organization Name (eg, company) [Internet Widgits Pty Ltd]:Private <Organization Name>
Organizational Unit Name (eg, section) []:Admin <Organization Name>
Common Name (e.g. server FQDN or YOUR name) []:Lepard 　<Host name>
Email Address []:sample@korodes.com&nbsp;&nbsp; <Administrator Email Address>

/etc/ssl/private # openssl req -x509 -nodes -newkey rsa:2048 -keyout vsftpd.pem -out vsftpd.pem -days 365
