    • ssh -l user@domain host
    • ssh domainuser@host

Login With SSH Keys

Usage from client-side (ssh)

  1. Generate a key pair on the client (preferably with a passphrase):
    • ssh-keygen -t rsa -f id_rsa
  2. Register private key with ssh-agent (optional, for single sign-on experience)
    • net start ssh-agent
    • ssh-add id_rsa
  3. Login using private key
    • ssh -i .id_rsa user@host (workgroup user)
    • ssh -i .id_rsa -l user@domain host (domain user)

Copying the public key securely. The OpenSSH tools include the SCP and SFTP utilities to make transferring keys completely secure. In order to properly configure a Windows client for authenticating via SSH keys, the public key (.PUB) file must be transferred to the client device’s.ssh directory and stored in the authorizedkeys text file. To use the user key that was created above, the public key needs to be placed on the server into a text file called authorizedkeys under users username.ssh. The OpenSSH tools include scp, which is a secure file-transfer utility, to help with this. Gta 5 license key generator online.

Setup server-side (sshd)

  1. Append contents of id_rsa.pub (client's public key) to the following file in corresponding user's directory %systemdrive%Users<user>.sshauthorized_keys (create one if needed).
  2. Double check access permissions on authorized_keys (only System, Administrators and owner can have access).icacls %systemdrive%Users<user>.sshauthorized_keys

Login using Kerberos Authentication

Setup server-side

  1. On a domain joined server, set GSSAPIAuthentication to yes in sshd_config
