1.FTP Server Installation

1. 1 vsftpd Install

# dnf -y install vsftpd

1	# dnf -y install vsftpd

1.2 Vsftpd configuration

Save the unedited vsftpd.conf with .bak

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

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

①Edit configuration file

# vi /etc/vsftpd/vsftpd.conf

●Line 12: Anonymous login prohibited (confirmation)
anonymous_enable=NO
●Line 39: Log transfer record (confirmation)
xferlog_enable=YES
●Lines 82,83 Uncomment ( Allow transfer in ASCII mode )
ascii_upload_enable=YES
ascii_download_enable=YES
●Lines 100,101: Uncomment ( chroot enabled )
chroot_local_user=YES
chroot_list_enable=YES
●Line 103 Uncomment ( chroot list file specified )
chroot_list_file=/etc/vsftpd/chroot_list
●Line 109 Uncomment ( Enable batch transfer by directory )
ls_recurse_enable=YES
●Line 114 Change ( Enable IPv4 )
listen=YES
●Line 123 Change (IPv6 is ignored)
listen_ipv6=NO
### Add to last line ###
# Use local time
use_localtime=YES

# vi /etc/vsftpd/vsftpd.conf

●Line 12: Anonymous login prohibited (confirmation)

anonymous_enable=NO

●Line 39: Log transfer record (confirmation)

xferlog_enable=YES

●Lines 82,83 Uncomment ( Allow transfer in ASCII mode )

ascii_upload_enable=YES

ascii_download_enable=YES

●Lines 100,101: Uncomment ( chroot enabled )

chroot_local_user=YES

chroot_list_enable=YES

●Line 103 Uncomment ( chroot list file specified )

chroot_list_file=/etc/vsftpd/chroot_list

●Line 109 Uncomment ( Enable batch transfer by directory )

ls_recurse_enable=YES

●Line 114 Change ( Enable IPv4 )

listen=YES

●Line 123 Change (IPv6 is ignored)

listen_ipv6=NO

### Add to last line ###

# Use local time

use_localtime=YES

②Add users to allow directory access to upper level

# echo "huong" >> /etc/vsftpd/chroot_list
In my case I wrote "huong".

1 2	# echo "huong" >> /etc/vsftpd/chroot_list In my case I wrote "huong".

③Specify IP addresses to allow connections in /etc/hosts.allow

# echo "vsftpd:192.168.11.0/24" >> /etc/hosts.allow
"192.168.11.0/24" is the setting that allows all local IP addresses in my environment.

1 2	# echo "vsftpd:192.168.11.0/24" >> /etc/hosts.allow "192.168.11.0/24" is the setting that allows all local IP addresses in my environment.

Write vsftpd:ALL (deny all connections) in /etc/hosts.deny

# echo "vsftpd:ALL" >> /etc/hosts.deny

1	# echo "vsftpd:ALL" >> /etc/hosts.deny

This setting overrides hosts.allow.
That is, everything is denied, and the IP address specified in hosts.allow is allowed

④Enable 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

# systemctl start vsftpd

# systemctl enable vsftpd

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

# systemctl start vsftpd

⑤From windows side, check if you can connect with FileZilla.
Open the ftp port with firewall before connecting

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

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

Start FileZilla and select "Site Manager" from the "File" menu.

Click on "New site"

Enter the following settings for each item and click "Connect"
Protocol　: FTP-File Transfer Protocol
Host　: Server IP Address
Port　:can be blank
Encryption　: Use expllict FTP ocver TLS if available
Logon Type　: Ask for password
User 　: General user name (server login user)

Set the password for the login user in "Password" and click "OK".

click "OK" when the following screen appears

If the connection is successful, the server directory is displayed 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/pki/tls/certs
# openssl req -x509 -nodes -newkey rsa:2048 -keyout /etc/pki/tls/certs/vsftpd.pem -out /etc/pki/tls/certs/vsftpd.pem
Generating a 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) [XX]:JP #country code
State or Province Name (full name) []:Osaka # Region (Prefecture)
Locality Name (eg, city) [Default City]:Sakai # city
Organization Name (eg, company) [Default Company Ltd]:private # Organization Name
Organizational Unit Name (eg, section) []:Admin # Organization Name
Common Name (eg, your name or your server's hostname) [] Lepard # Server Host Name
Email Address []: # Administrator's email address

# cd /etc/pki/tls/certs

# openssl req -x509 -nodes -newkey rsa:2048 -keyout /etc/pki/tls/certs/vsftpd.pem -out /etc/pki/tls/certs/vsftpd.pem

3.8 Accessing shared directories from Windows 11

①Enable SMB1.0/CIFS in Windows as a preliminary preparation
To enable it, open "Moe Windows features" at the bottom of "Apps" and "Optional features" in the "Settings" menu of Windows, and check "SMB1.0/CIFS File Sharing Support" as shown below. Enable it.

②Connect from Windows Explorer
Open File Explorer and enter "\\(in this case 192.168.11.83)" in the address field.
Access the server.

Enter authentication information
User name　:　User name created in "3.6 User (smbuser) Registration, Password Setting, Group Registration
Password　 :　Password for the above user
Click "OK"

Confirm that files and folders are newly created when the shared directory information is displayed.
