In Visual Studio, choose Tools > Options on the menu bar to open the Options dialog. Connect to the remote system in Visual Studio Now you're ready to set up the Visual Studio connection. Use it to sign in from Windows: ssh -i %USERPROFILE%\.ssh\id_rsa successfully set up ssh, created and deployed encryption keys, and tested your connection. Now, you can test to see if the new key works in ssh. We recommend you use a passphrase for increased security.įrom Windows, copy the public key to the Linux machine: scp %USERPROFILE%\.ssh\id_rsa.pub the Linux system, add the key to the list of authorized keys, and ensure the file has the correct permissions: cat ~/id_rsa.pub > ~/.ssh/authorized_keys (In PowerShell, use $env:USERPROFILE instead of the cmd macro %USERPROFILE%) If you change the key name, use the changed name in the steps that follow. By default, the keys are saved to %USERPROFILE%\.ssh\id_rsa and %USERPROFILE%\\.ssh\\id_rsa.pub. The command creates a public key and a private key. On the Windows machine, generate a public/private RSA key pair by using this command: ssh-keygen -t rsa -b 4096 -m PEM Then you'll copy the public key to the remote Linux system for use by ssh. Next, you'll create an RSA key pair on your Windows computer. For more information, see the man page for sshd_config or the article SSH Server Configuration.Īfter saving and closing sshd_config, restart the ssh server to apply the new configuration: sudo service ssh restart Some other relevant security options you may want to consider are PermitRootLogin, PasswordAuthentication, and PermitEmptyPasswords. You can configure ssh to use other ciphers, host key algorithms, and so on. The ecdh-* key exchange algorithms are FIPS compliant, but Visual Studio doesn't support them. The aes*-ctr algorithms are also FIPS compliant, but the implementation in Visual Studio isn't approved. Ssh-rsa is the only FIPS compliant host key algorithm VS supports. KexAlgorithms diffie-hellman-group-exchange-sha256,diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1 Edit (or add, if they don't exist) the following lines: Ciphers aes256-cbc,aes192-cbc,aes128-cbc,3des-cbc If you'd like the ssh server to start automatically when the system boots, enable it using systemctl: sudo systemctl enable ssh On the Linux system, install and start the OpenSSH server: sudo apt install openssh-server To set up the SSH server on the remote system However, the instructions should be the same for any distro using a moderately recent version of OpenSSH. The examples in this article use Ubuntu 18.04 LTS with OpenSSH server version 7.6. For FIPS-140-2 compliance, Visual Studio only supports RSA keys. Some preparation is required to use a FIPS-compliant, cryptographically secure ssh connection between Visual Studio and your remote Linux system. ![]() This article is the FIPS-compliant version of the connection instructions in Connect to your remote Linux computer. This guide is applicable when you build CMake or MSBuild Linux projects in Visual Studio. Here's how to set up a secure, FIPS-compliant connection between Visual Studio and your remote Linux system. In Visual Studio 2019 version 16.5 and later, you can use a secure, FIPS-compliant cryptographic connection to your Linux system for remote development. Windows has validated support for FIPS-compliant cryptographic modules. ![]() Implementations of the standard are validated by NIST. government standard for cryptographic modules. Federal Information Processing Standard (FIPS) Publication 140-2 is a U.S.
