OpenSUSE15.5 ; OS Install

OpenSUSEとは OpenSUSE is a Linux distribution that is community-based, free to the public, and active in adopting the latest technologies. It is sponsored by Novell and developed by the community. Originally, SUSE Linux was developed by SUSE, but after the acquisition of SUSE by Novell in 2003, Novell shifted the development structure to community-based by the OpenSUSE project as a distribution aiming for 100% open source, and changed the name from SUSE Linux to OpenSUSE Linux The name was changed to the current name. openSUSE is available as Leap, the stable version, and Tumbleweed, which uses a rolling-release model and is also the basis for the paid-for version of SUSE Linux Enterprise.

Ubuntu Server24.04 ; Initial settings after OS installation

1. Set root password and use SU command In the default configuration of Ubuntu, the root user is unavailable because no password has been set. By setting a password for the root user, transitions using the traditional [su] command will be possible. 3. Make locate command available The find command is often used to search for specific files throughout the Linux system, but find is somewhat confusing in terms of specifying options. The locate command can extract all files with a specified filename. 4. vim editor settings Ubuntu has vim installed by default 4.1 Change vim settings There may be cases where you do not want to allow vim settings for all users. In such cases, a ".vimrc" file can be created in each user's home directory to change the vim environment for each user. In this case, we will create a ".vimrc" file in the root user's home directory "/root/" and apply it to all users.

FreeBSD14.1 ; OS INSTALL

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 14.0, released on Nov 14, 2023, 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

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_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).
