Access to instances
Creating instances¶
Follow the guide for Basic creation of a new VM instance and network configuration here to get your floating IP address, username, and private key.
The default username is usually named after the Linux distribution; for Ubuntu, it will be 'ubuntu', etc.
To connect using Windows (version 1803 or later), use the command prompt or terminal application:
ssh username@floating_IP -i C:\myfiles\private_key\id_ecdsa
For example:
ssh ubuntu@10.200.132.62 -i C:\mojepliki\Klucze_certy\id_ecdsa
The authenticity of host '10.200.132.62' can't be established. RSA key fingerprint is SHA256:xxx. Are you sure you want to continue connecting (yes/no)?
You'll need to modify the ACL permissions. Disinherit permission for the private key file and leave only the account we're working on.
To connect to a Windows instance, access it via the Windows interface.
You can set a password during installation, or afterward, using the private key to read the randomly assigned password (see step 1).
a) Set the password during installation:
On the 'Metadata' tab > System > Password > enter the 'admin_pass'.
b) Read the password using a private key:
c) The password in OpenStack is stored as plain text, so you should change it immediately after the first login.
d) Add a firewall exception for RDP access. If your instance is 'exposed to the world', this rule should only allow traffic from a specific IP address or range. The below example shows a rule to allow all incoming traffic for demonstration purposes:
