1.Disabling SELinuxFirst, disable selinux. selinux is a feature that improves auditing and security in Linux, but when enabled, it places considerable restrictions on the behavior of services and on what can be configured. Therefore, it is basically disabled in many cases.SELinux operating modesEnforcing : SELinux functionality is enabled and access control is enabledPermissive : SElinux will warn, but no access restrictions will be placeddisabled : Both SElinux function and access control are disabled2.System ModernizationPackage updates are performed as soon as possible immediately after OS installation.However, when a dnf update is performed, a kernel update is also performed at the same time.A kernel update may require rebooting the system or stopping services, or worse, a kernel panic may occur and the system may not boot. It is wiser to exclude the kernel from the update.The kernel can be excluded from updates by running dnf -y update with "--exclude=kernel*" after it.

FreeBSD13.2 ; Initial setting (Update binaries, Packages and Ports Collection)

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).
