4. Openssh In Vs Code

The VS Code Remote - SSH extension allows you to connect to a remote machine or VM using SSH, all from inside VS Code. If you don't already have the Remote - SSH extension installed, you can search for 'remote ssh' in the Extensions view (Ctrl + Shift + X). You'll have noticed an indicator on the bottom-left corner of the Status bar. Sudo chmod a+rwx /etc/nginx/sites-enabled/default. (or whatever your path to server config file is). You can then ssh with VSCode and save the edited file freely. If you don't like working in vim through the command line and want to use VSCode to edit server config files, this might be the quickest solution.

Linux support is available in Visual Studio 2017 and later.

You can configure a Linux project to target a remote machine or the Windows Subsystem for Linux (WSL). For both remote machines and for WSL, you need to set up a remote connection in Visual Studio 2017.

You can configure a Linux project to target a remote machine or the Windows Subsystem for Linux (WSL). For a remote machine, you need to set up a remote connection in Visual Studio. To connect to WSL, skip ahead to the Connect to WSL section.

When using a remote connection, Visual Studio builds C++ Linux projects on the remote machine. It doesn't matter if it's a physical machine, a VM in the cloud, or WSL.To build the project, Visual Studio copies the source code to your remote Linux computer. Then, the code gets compiled based on Visual Studio settings.

Note

Visual Studio 2019 version 16.5 and later also supports secure, Federal Information Processing Standard (FIPS) 140-2 compliant cryptographic connections to Linux systems for remote development. Nivo driver download. To use a FIPS-compliant connection, follow the steps in Set up FIPS-compliant secure remote Linux development instead.

Set up the SSH server on the remote system

If ssh isn't already set up and running on your Linux system, follow these steps to install it. The examples in this article use Ubuntu 18.04 LTS with OpenSSH server version 7.6. Aquarius server e30 s10 driver download for windows. However, the instructions should be the same for any distro using a moderately recent version of OpenSSH.

1. On the Linux system, install and start the OpenSSH server:

2. If you’d like the ssh server to start automatically when the system boots, enable it using systemctl:

Set up the remote connection

1. In Visual Studio, choose Tools > Options on the menu bar to open the Options dialog. Then select Cross Platform > Connection Manager to open the Connection Manager dialog.

   If you haven't set up a connection in Visual Studio before, when you build your project for the first time, Visual Studio opens the Connection Manager dialog for you.

2. In the Connection Manager dialog, choose the Add button to add a new connection.

   In either scenario, the Connect to Remote System window is displayed.

3. Enter the following information:

   Entry	Description
   Host Name	Name or IP address of your target device
   Port	Port that the SSH service is running on, typically 22
   User name	User to authenticate as
   Authentication type	Password and Private Key are both supported
   Password	Password for the entered user name
   Private key file	Private key file created for ssh connection
   Passphrase	Passphrase used with private key selected above

   You can use either a password or a key file and passphrase for authentication. For many development scenarios, password authentication is sufficient, but key files are more secure. If you already have a key pair, it's possible to reuse it. Currently Visual Studio only supports RSA and DSA keys for remote connections.

4. Choose the Connect button to attempt a connection to the remote computer.

   If the connection succeeds, Visual Studio configures IntelliSense to use the remote headers. For more information, see IntelliSense for headers on remote systems.

   If the connection fails, the entry boxes that need to be changed are outlined in red.

   If you use key files for authentication, make sure the target machine's SSH server is running and configured properly.

Host key verification

In Visual Studio version 16.10 or later, you will be asked to verify the host key fingerprint presented by the server when Visual Studio connects to a remote system for the first time. You may be familiar with this if you’ve used the OpenSSH command-line client or PuTTY before. The fingerprint identifies the server and is used to ensure that Visual Studio is connecting to the intended and trusted server.

You will be asked to accept or deny the host key fingerprint presented by the server the first time a new remote connection is established, or anytime that a cached fingerprint has changed. You can also verify a fingerprint on demand by selecting a connection in the Connection Manager and clicking 'Verify.'

If you are upgrading to Visual Studio 16.10 from an older version of Visual Studio, then all existing remote connections will be treated as a new connection. You will be prompted to accept the host key fingerprint before a connection is established and the accepted fingerprint will be cached.

You can also update remote connections from ConnectionManager.exe using the update argument.

Supported SSH algorithms

Starting in Visual Studio version 16.9, support for older, insecure SSH algorithms used to encrypt data and exchange keys, has been removed. Only the following algorithms are supported. They are supported for both client-to-server and server-to-client SSH communication:

Configure the SSH server

First, a little background. You can't select the SSH algorithm to use from Visual Studio. Instead, the algorithm is determined during the initial handshake with the SSH server. Each side (client and server) provides a list of algorithms it supports, and then the first algorithm common to both is selected. As long as there is at least one algorithm in common between Visual Studio and the server for encryption, HMAC, key exchange, and so on, the connection will succeed.

The Open SSH configuration file (sshd_config) doesn't configure which algorithm to use by default. The SSH server should use secure defaults when no algorithms are specified. Those defaults depend on the version and vendor of the SSH server. If Visual Studio doesn't support those defaults, or the SSH server is configured to use algorithms that Visual Studio doesn't support, you'll likely see an error like: Could not connect to the remote system. No common client to server HMAC algorithm was found.

A default SSH server on most modern Linux distributions should work out-of-the-box with Visual Studio. But if you're running an older SSH server that is configured to use older, insecure algorithms, the following explains how to update to more secure versions.

In the following example, the SSH server uses the insecure hmac-sha1 algorithm, which isn't supported by Visual Studio 16.9. If the SSH server uses OpenSSH, you can edit the /etc/ssh/sshd_config file as shown below to enable more secure algorithms. For other SSH servers, refer to the server's documentation for how to configure them.

First, verify that the set of algorithms your server is using includes algorithms supported by Visual Studio. Run the following command on the remote machine, and it will list the algorithms supported by the server.

It will produce output like:

This output will list all the encryption, HMAC, key exchange, and host key algorithms supported by your SSH server. If this list doesn't include algorithms supported by Visual Studio, then you'll need to upgrade your SSH server before proceeding.

You can enable algorithms supported by Visual Studio by editing /etc/ssh/sshd_config on the remote machine. The following examples show how to add various types of algorithms to that configuration file.

These examples can be added anywhere in /etc/ssh/sshd_config. Ensure that they are on their own lines.

After editing the file, restart the SSH server (sudo service ssh restart on Ubuntu) and attempt to connect again from Visual Studio.

Cipher example

Add: Ciphers <algorithms to enable>
For example: Ciphers aes128-cbc,aes256-cbc

HMAC example

Add: MACs <algorithms to enable>
For example: MACs hmac-sha2-256,hmac-sha2-512

Key exchange example

Add: KexAlgorithms <algorithms to enable>
For example: KexAlgorithms ecdh-sha2-nistp256,ecdh-sha2-nistp384

Host key example

Add: HostKeyAlgorithms <algorithms to enable>
For example: HostKeyAlgorithms ssh-dss,ssh-rsa

Logging for remote connections

You can enable logging to help troubleshoot connection problems. On the menu bar, select Tools > Options. In the Options dialog, select Cross Platform > Logging:

Logs include connections, all commands sent to the remote machine (their text, exit code and execution time), and all output from Visual Studio to the shell. Logging works for any cross-platform CMake project or MSBuild-based Linux project in Visual Studio.

You can configure the output to go to a file or to the Cross Platform Logging pane in the Output window. For MSBuild-based Linux projects, MSBuild commands sent to the remote machine aren't routed to the Output Window because they're emitted out-of-process. Instead, they're logged to a file, with a prefix of 'msbuild_'.

Command-line utility for the Connection Manager

Visual Studio 2019 version 16.5 or later: ConnectionManager.exe is a command-line utility to manage remote development connections outside of Visual Studio. It's useful for tasks such as provisioning a new development machine. Or, you can use it to set up Visual Studio for continuous integration. For examples and a complete reference to the ConnectionManager command, see ConnectionManager reference.

TCP Port Forwarding

Visual Studio's Linux support has a dependency on TCP port forwarding. Rsync and gdbserver are affected if TCP port forwarding is disabled on your remote system. If you're impacted by this dependency, you can upvote this suggestion ticket on Developer Community.

rsync is used by both MSBuild-based Linux projects and CMake projects to copy headers from your remote system to Windows for use by IntelliSense. When you can't enable TCP port forwarding, disable the automatic download of remote headers. To disable it, use Tools > Options > Cross Platform > Connection Manager > Remote Headers IntelliSense Manager. If the remote system doesn't have TCP port forwarding enabled, you'll see this error when the download of remote headers for IntelliSense begins:

rsync is also used by Visual Studio's CMake support to copy source files to the remote system. If you can't enable TCP port forwarding, you can use sftp as your remote copy sources method. sftp is often slower than rsync, but doesn't have a dependency on TCP port forwarding. You can manage your remote copy sources method with the remoteCopySourcesMethod property in the CMake Settings Editor. If TCP port forwarding is disabled on your remote system, you'll see an error in the CMake output window the first time it invokes rsync.

Vscode Ssh Terminal

gdbserver can be used for debugging on embedded devices. If you can't enable TCP port forwarding, then you must use gdb for all remote debugging scenarios. gdb is used by default when debugging projects on a remote system.

Connect to WSL

In Visual Studio 2017, you use the same steps to connect to WSL as you use for a remote Linux machine. Use localhost for the Host Name.

Visual Studio Code Ssh Remote Development

Visual Studio 2019 version 16.1 added native support for using C++ with the Windows Subsystem for Linux (WSL). That means you can build and debug on your local WSL installation directly. You no longer need to add a remote connection or configure SSH. You can find details on how to install WSL here.

To configure your WSL installation to work with Visual Studio, you need the following tools installed: gcc or clang, gdb, make, ninja-build (only required for CMake projects using Visual Studio 2019 version 16.6 or later), rsync, and zip. You can install them on distros that use apt by using this command, which also installs the g++ compiler:

For more information, see Download, install, and set up the Linux workload.
