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).

FreeBSD14.1 : Jail Install

JailIt is a mechanism that allows multiple virtual FreeBSD environments to be created on a FreeBSD environment.A jail is an extension of chroot, and a jail environment (called a prisoners) built on a host ring (called a jailer) behaves as a FreeBSD machine running separately from the host environment.The prisoner cannot directly attach to the jailer or another parallel prisoner.Features of JAIL・High speed operation because it is not emulation.・Each prisoner can be assigned an IP address different from that of the jailer.・Since the same file system is used for a jailer and a prisoner, it is necessary to be careful about the assignment of UID/GID.This time, build two prisoners (prisoner1 and prisoner2) in jailer (FreeBSD14.1)
