Установка OpenSSH на Windows

Для чего устанавливать OpenSSH на Windows устройства?

OpenSSH на Windows используется для сбора информации о системе, для ротации паролей локальных УЗ Windows и для автоматического создания локальных УЗ.

Установка OpenSSH

Вам достаточно просто запустить установочный дистрибутив OpenSSH-Win64.msi с правами администратора. Никаких настроек выполнять не нужно.

Для более безопасного подключения можно настроить авторизацию с помощью приватного ключа.

Настройка авторизации с помощью приватного ключа

ssh-keygen.exe -t rsa
cp $env:USERPROFILE\.ssh\id_rsa.pub $env:USERPROFILE\.ssh\authorized_keys
notepad C:\ProgramData\ssh\sshd_config
# This is the sshd server system-wide configuration file.  See
# sshd_config(5) for more information.

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented.  Uncommented options override the
# default value.
