FreeBSD13.3_en

FreeBSD FreeBSD is UNIX-like open source OS software. In particular, its performance as a network operating system exceeds that of Linux-based systems, and it maintains stable performance even under high loads. FreeBSD is designed to be robust and sturdy with an emphasis on practicality, making it suitable for operating FTP, WWW, and e-mail servers for major companies and services. In this project, we will install FreeBSD 13.3, released on March 5, 2024, and build the server. Features High-speed, high-performance multi-platform capable of withstanding high workloads Adopted by many major companies Network security measures can be applied by restricting access Capable of operating small to large servers More than 33,000 dedicated software applications from commercial to personal use

After installing FreeBSD, we will start building the server, but it is difficult to work on the console screen, so we will change the SSH connection settings for now in order to operate the server from Windows using TeraTerm or other software. Enter the following command on the FreeBSD console screen # vi /etc/ssh/sshd_config Line 61. #PasswordAuthentication no →　PasswordAuthentication yes Make the changes and reflect the settings with the following command # service sshd restart Now you can connect via SSH from TeraTerm on Windows (see the default settings for other operating systems for settings in TeraTerm).

It allows users to make numerous changes to internal OS settings such as user and disk usage limits, services, configuration files, etc., and to modify and control many open source applications such as Apache, PHP, MySQL, and others. Webmin is built primarily in Perl and runs as its own process and web server. By default, it communicates on TCP port 10000.

1. Obtaining a certificate for the mail server Obtain a certificate for the mail server to convert the mail server to SSL/TLS. Use the certbot that was used when the web server was converted to SSL. Stop the web server and execute the following command
