2. Vsftpd Over SSL/TLS
①Create a self-signed certificate.
If you are using a trusted, legitimate certificate such as Let's Encrypt, you do not need to do this work.
# cd /etc/ssl/private
# openssl req -x509 -nodes -newkey rsa:3072 -keyout vsftpd.pem -out vsftpd.pem -days 3650
---------------------------------------------------------------------------
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
State or Province Name (full name) [Some-State]:Osaka
Locality Name (eg, city) []:Sakai
Organization Name (eg, company) [Internet Widgits Pty Ltd]:private
Organizational Unit Name (eg, section) []:Admin
Common Name (e.g. server FQDN or YOUR name) []:Lepard
Email Address []:[管理者アドレス]

File server installation with Samba
Build a file server with access rights that requires user authentication with Samba.
Installation Procedure
(1) Create a shared folder with access rights that requires user authentication.
(2) Create a group with access rights
(3)Create users belonging to groups that can be accessed
(4)Edit configuration file
① samba install
# apt -y install samba
➁ Create a shared folder (smbshare)
# mkdir /home/smbshare
➂ Create accessible group (smbgroup)
# groupadd smbgroup
# chgrp smbgroup /home/smbshare
# chmod 770 /home/smbshare
④ Configuration File Edit
# vi /etc/samba/smb.conf
Line 25 :
[global]
unix charset = UTF-8 # Add
dos charset = CP932 # Add
Line 41 : Add networks to allow access
interfaces = 127.0.0.0/8 192.168.11.0/24 ens33
Line 106 : Comment out and add below
#map to guest = bad user
security = user
Add to the last line
Set any shared name
[Smbshare]
# Specify a shared folder
path = /home/smbshare
# Allow posting
writable = yes
# Do not allow guest users
guest ok = no
# [smbgroup] Allow access only to the group
valid users = @smbgroup
# Set the group to [smbgroup] when creating files
force group = smbgroup
# Set the permissions to [770] when creating the file.
force create mode = 770
# Set the permissions to [770] when creating folders.
force directory mode = 770
# Inherit permissions from the parent folder
inherit permissions = yes
⑤ SMB start
# systemctl enable smbd
# systemctl start smbd
⑥ User (smbuser) registration, password setting, group registration
# useradd smbuser
# smbpasswd -a smbuser
New SMB password: # Password Setup
Retype new SMB password:
Added user smbuser.
smbuserをsmbgroupにする
# usermod -aG smbgroup smbuser
⑦ UFW to allow Samba services
# ufw allow samba
# ufw reload
⑧ Accessing shared directories from Windows 11
Connect from Windows Explorer
Open Explorer and enter "\\server IP" (in this case 192.168.11.83) in the address field.
