When you create an instance, Eucalyptus assigns the instance two IP addresses: a public IP address and a private IP address. The public IP address provides access to the instance from external network sources; the private IP address provides access to the instance from within the Eucalyptus cloud environment. Note that the two IP addresses may be the same depending on the current networking mode set by the administrator. For more information on Eucalyptus networking modes, see the Eucalyptus Administrator’s Guide.
To use an instance you must log into it via ssh using one of the IP addresses assigned to it. You can obtain the instance’s IP addresses using the euca-describe-instances query as shown in the following example.
To log into a VM instance:
RESERVATION r-338206B5 alice default INSTANCE i-4DCF092C emi-EC1410C1 192.168.7.24 10.17.0.130 ↵ running alice-keypair 0 m1.small 2010-03-15T21:57:45.134Z
Note that the public IP address appears after the image name, with the private address immediately following.
ssh -i alice-keypair.private firstname.lastname@example.org
If you are a Windows user and want to securely connect to instances via PuTTY, you must first have a key pair.
Log into Windows VM instances using a Remote Desktop Protocol (RDP) client. An RDP prompts you for a login name and password. By default, Windows VM instances are configured with a single user (named Administrator) and a random password generated at boot time. So, before you can log into a Windows VM instance via RDP, you must retrieve the random password generated at boot time using the euca-get-password command.
To log into a Windows instance:
The response from this command will look like the following example.
