Установка и настройка SFTP сервера (SSH FTP) в Windows на базе OpenSSH

С помощью официального пакета OpenSSH для Windows вы можете с легкостью организовать безопасный обмен файлами между клиентом и серверов Windows по защищенному протоколу передачи файлов SFTP (Secure FTP). В этой статье мы покажем, как с помощью Win32-OpenSSH установить SFTP сервер на Windows 10 или Windows Server 2016/2012R2.

Особенности протокола SFTP

Протокол SFTP (Secure File Transfer Protocol , Secure FTP или SSH FTP) это расширение протокола SSH, являющимся стандартом мира UNIX/Linux систем. Хотя с точки зрения пользователей он похож на FTP, но на самом деле это абсолютно другой протокол, не имеющий с FTP ничего общего. Данные между клиентом и сервером передаются по порту 22 через SSH туннель.

Основные преимущества протокола SFTP:

• Передача файлов и команд происходит внутри защищенной SSH-сессии;
• Для передачи файлов и команд используется одно соединение;
• Поддержка символических ссылок, функций прерывания, возобновления передачи, удаления файла и пр;
• Как правило, на каналах, где FTP работает медленно или с перебоем, SFTP-соединение работает более надежно и быстро;
• Возможность аутентификации с помощью SSH ключей.

Реализация SFTP в системах Windows

Исторически в операционных системах Windows отсутствуют встроенные средства для организации защищенного SFTP сервера. Для этих целей обычно использовались открытые или коммерческие решения, к примеру, Core FTP, FileZilla, CYGWIN, OpenSSH, FTP Shell, IPSwitch и пр. Однако несколько лет назад Microsoft выпустила свою версию порта OpenSSH для win32. Данный проект называется Win32-OpenSSH.

Рассмотрим процесс настройки SFTP сервера в Windows 10 и Windows Server 2016/2012 R2 с помощью пакета Win32-OpenSSH.

Установка Win32 OpenSSH в Windows 10 1803+/Windows Server 2019

В Windows 10, начиная с билда 1803, и в Windows Server 2019 пакет OpenSSH (как и RSAT) уже включен в операционную систему в виде Feature on Demand (FoD).

В Windows 10 и Windows Server 2019 вы можете установить сервер OpenSSH с помощью командлета PowerShell:

Add-WindowsCapability -Online -Name OpenSSH.Server*

Или с помощью DISM:
dism /Online /Add-Capability /CapabilityName:OpenSSH.Server

Или можно установить OpenSSH из графического интерфейса Windows 10 (Settings -> Apps -> Optional Features -> Add a feature -> Open SSH Server -> Install).

Исполняемые файлы OpenSSH находятся в каталоге:

Конфигурационный файл sshd_config находится в каталоге C:\ProgramData\ssh (каталог создается после первого запуска службы).

Файл authorized_keys и ключи хранятся в каталоге %USERPROFILE%\.ssh\.

Установка Win32 OpenSSH на Windows Server 2016/2012 R2

В предыдущих версиях Windows 10 и в Windows Server 2016/2012 R2 вы должны скачать и установить OpenSSH с GitHub (https://github.com/PowerShell/Win32-OpenSSH/releases). Нам нужна версия для 64 битной версии Windows: OpenSSH-Win64.zip (3,5 Мб).

1. Распаковываем содержимое архива в целевой каталог, к примеру: C:\OpenSSH-Win
2. Запускаем командную строку PowerShell с правами администратора и переходим в каталог OpenSSH: Cd C:\OpenSSH-Win
3. Добавьте путь к каталогу OpenSSH в переменную окружения Path;
4. Установите сервер OpenSSH: .\install-sshd.ps1 (должно появиться зеленое сообщение “sshd and ssh-agent services successfully installed”);
5. Сгенерируйте SSH ключи для сервера (нужны для запуска службы sshd): ssh-keygen.exe –A

, убедитесь, что создан каталог %programdata%\ssh.

Тестируем SFTP подключение с помощью WinSCP

Попробуем подключиться к поднятому нами SSH серверу по протоколу SFTP. Для этих целей воспользуемся свободным клиентом WinSCP.

В окне настройки подключения выберите протокол передачи файлов SFTP, укажите имя сервера и данные учетной записи Windows, под которой осуществляется подключение (возможно также настроить авторизацию по ключам).При первом подключении появится окно с предупреждением о том, что ключ хоста отсутствует в локальном кеше.

Если все настроено правильно, клиент должен подключиться к SFTP серверу и отобразить список файлов в домашнем каталоге пользователя (по умолчанию каталог с профилем пользователя).

С помощью привычного интерфейса файлового менеджера можно безопасно копировать файлы между сервером и клиентом. Передача файлов будет осуществляться по защищённому протоколу SFTP.

Удаление службы Win32 OpenSSH

Чтобы корректно удалить службу Win32 OpenSSH из системы:

1. Откроем консоль Powershell с правами администратора
2. Остановим службу SSHD: Stop-Service sshd
3. Удалим службу OpenSSD:Удалим ключи: .\uninstall-sshlsa.ps1

Portable Use

Using Portable Executable

WinSCP can be downloaded in the form of standalone Portable executables. The executables in the Portable executables package are identical to the executables in an Installation package. The difference is that the installer pre-configures the executables to override their default portable behavior.

Portable executables are intended for advanced users and specific needs. For general use, use installer.

On startup, the Portable executable looks for an INI file in the directory from which it was started. The INI file must have an .ini extension and the same name as the executable. If the executable does not find any, it creates one with a default configuration. This allows you to easily carry WinSCP with your configuration on a removable media or a USB drive. For details, see auto-selecting configuration storage.

You may also use an INI file in a different folder or with a different name using an /ini switch.

Full Portability

With default configuration WinSCP still stores some temporary data on the file system of the host computer. You can configure WinSCP to be completely portable though, i.e. make it store all its files and configuration in one place – for example, a portable USB drive.

WinSCP stores by default these files to the host computer:

• Random seed file (file winscp.rnd in C:\Users\username folder);
• Temporary files (system temporary folder).

You can force WinSCP to store the files into different locations in preferences. You can use local paths relative to the WinSCP start folder.

To change the storage directly in an INI file, to the same locations where WinSCP is started from, set following parameters:

12 Best SFTP Server Software for Windows in 2021

With the rise of distributed networks, finding a secure way to transfer files and data is essential. That’s where software products like Secure File Transfer Protocol, better known as SFTP, comes in.

File Transfer Protocol has been around since 1971; the encrypted version was developed in 1994. This popular file transfer communication protocol is able to make sure that your data is able to travel to remote servers safely over unsecured mediums such as the Internet etc.

SFTP was created as an extension for the Secure Shell protocol (SSH) 2.0 as a way to bolster security during file transfers. It also supports file access and management in environments that don’t have data or command channels.

With this software, the commands and data are encrypted and transported in secure packets through one secure connection running on TCP port 22.

Unlike the legacy FTP protocol which requires a control/command connection (TCP port 21) and a data connection (TCP port 20), the SFTP protocol works exclusively over TCP port 22.

Aside from security, why do you need to use SFTP software?

File transfer protocol (FTP) is used to send data packets from one server to another, but data packets are not encrypted.

SSH protocol on the other hand provides a set of rules and guidelines for the safe conduct of data communications in unsecure environments. SFTP server software makes use of SSH and requires a dedicated SFTP client for performing the file transfer.

Authentication with SFTP server software encrypts data in two ways. First, the authentication mechanism asks for a password and user ID that allows a connection to the system. Next, SSH keys are used to verify the user ID and password, which requires having a public and private key; the SSH keys can also be used alone, but two-factor authentication provides better security.

Table of Contents

What are the Advantages of Using SFTP Over FTP?

Aside from the advantage of having multiple layers of encryption, there are other benefits to installing SFTP server software.

• Faster file transfers due to the binary format; speed is second only to security for providing user satisfaction.
• No need for a dedicated control channel because SFTP uses a single connection for both control and data packets.
• Consistent security through SSH; it can’t be turned off or disabled by anyone.
• Machine readable format.
• Also includes operations for performing file locking, permissions, and manipulating attributes.

Comments

With the new versions of Windows 10, and I believe also Windows Server, it is fairly easy to setup OpenSSH’s SFTP server. I wrote out simple directions to configure and use it with ISE on my blog at https://packitforwarding.com/index.php/2019/05/08/windows-server-openssh-for-cisco-ise/

Looks like you are missing Couchdrop.io? May not be software, but it is an incredible cloud SFTP service?

Network Master says

Titan Ftp Server, /n Software and Rebex Tiny Sftp Server are great products. I’ve used Titan for over 10 years for both my Cisco backups and for giving file access to remote users (Titan has an optional web browser connection that’s easy to use and I don’t have to help remote users configure it). That said, serv-u and Filezilla are complete garbage! If you really want a “best of” list, you should remove these. Serv-u crashed all the time for me, and there support is horrible. Filezilla is loaded with spyware.

Thanks for mentioning Titan SFTP Server here. I work for the developer of the product, and wanted to clarify that the company name is actually SRT and not Titan. I also wanted to briefly comment on the cost of Titan SFTP and hopefully shine some light on why the cost may seem higher than other products listed.

A full year of technical support is included with your initial purchase, and subsequent support renewals are offered at a discount. Our support agents all have at least 8 years of experience with SRT products, and the original developers are still with the company. All of our support engineers are Tier 2 and 3, so you’ll never get someone simply reading questions off of a list– support is tailored to the customer and their experience.

We are also committed to staying ahead of the current security standards, so customers never have to worry about lagging behind.
