Although it is certainly possible to enter in any configuration commands directly to the VM's command line console, many users find it easier to SSH (Secure Shell) to the VM and type commands through the command line on their host OS. Below are the general steps and commands to access the VM through SSH.
Step 1: Log in
Log into the VM as the system user with the name and password shown at the top of the VM upon start up.
Step 2: Generate SSH keys on the VM
Now that you're logged in, the SSH keys to access the VM need to be generated. Type the following commands, filling in for the text between the brackets:
mkdir -p .ssh
ssh-keygen -f '<filename for SSH key>' -C '<comment for file>' -N '' -t rsa
This should generate two files, a private SSH key with the name that you entered for it, and a public key as well (ending in .pub). Now add the keys that you generated to the VM's list of authorized keys with the command:
cat <your public SSH key>.pub >> authorized_keys
Step 3: Move the keys to a space you can access from your host OS
Now that you have generated the keys, you will need to access them from your host OS. To achieve this, the following commands will place the SSH keys in a place on the VM that you will be able to retrieve from your host OS via SFTP.
sudo mkdir /sftp/transfer/data/keys
sudo mv /home/system/.ssh/<private SSH key> /sftp/transfer/data/keys
sudo mv /home/system/.ssh/<public SSH key>.pub /sftp/transfer/data/keys
sudo chmod 644 /sftp/transfer/data/keys/<private SSH key>
sudo chmod 644 /sftp/transfer/data/keys/<public SSH key>.pub
Step 4: Retrieve the keys from your host OS
The keys have now been generated and stored in a place that can be accessed by the host OS, so the last step is to pull them down and SSH to the system via the following commands:
sftp -P <22 or 2222 depending on your system> [email protected]<IP or Hostname of your VM>
<enter transfer password> This password is available on the login screen in the VM console at startup.
get <private SSH key>
get <public SSH key>.pub
The keys will now be stored in your working directory on your Host OS. To see where those files are located, type
lpwd. The downloaded private key needs to be changed to be read-only by just your user and unreadable by any other users on your system. On OSX or Linux, the command to run locally is:
chmod 600 <private SSH key>
The final step is to SSH to the system using this command and the newly downloaded key:
ssh -p <2222 or 22> -i <path_to_private_key> [email protected]<IP or Hostname of your VM>
After a successful SSH connection is established, it is advised that you log into the VM as the system user (as described above) and delete your SSH keys from the directory /emcien_feed/data/keys.
