FreeBSD14.1_en FreeBSD14.1 ; OS INSTALL
FreeBSDFreeBSD 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 14.0, released on Nov 14, 2023, and build the server.FeaturesHigh-speed, high-performance multi-platform capable of withstanding high workloadsAdopted by many major companiesNetwork security measures can be applied by restricting accessCapable of operating small to large serversMore than 33,000 dedicated software applications from commercial to personal use
FreeBSD14.1_en FreeBSD14.1 ; Initial setting (Update binaries, Packages and Ports Collection)
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_configLine 61.#PasswordAuthentication no → PasswordAuthentication yes Make the changes and reflect the settings with the following command# service sshd restartNow you can connect via SSH from TeraTerm on Windows (see the default settings for other operating systems for settings in TeraTerm).
