Use SSH to connect to the SSH bastion and then to the Linux instance.
For more information about the friendly bastion names, see DNS bastions.
In order to connect to the Linux instance, you must first connect to an SSH bastion.
Open a shell window and enter:
ssh
Domain_FQDN
\\Username
@SSH_bastion_name
orSSH_bastion_IP
Which would look like this if your Domain_FQDN is "corp.domain.com", your account number is "123456789123", Your_Domain is "amazonaws.com", you choose bastion "4", and your user name is "JoeSmith":
ssh corp.domain.com\\JoeSmith sshbastion4.A123456789123.amazonaws.com
Log in with your corporate Active Directory credentials.
When presented with a Bash prompt, SSH in to the instance, and then enter:
ssh
Domain_FQDN
\\Username
@Instance_IP
Or, you can use the Login flag (-l):
ssh -l
Domain_FQDN
\\Username
@Instance_IP
