Hi Aishwarya,
The basic requirement here is that anyone - which really means a combination of
a computer or instance, plus a user on that computer/instance - needs to have
the private key that matches the public key that is installed on the target
instance.
You've asked about logging in from your first instance - let's call it A - so
you need to save the private key in a file on A - let's call it private_key -
and give it 600 permissions:
chmod 600 private_key
Then you can use this key with SSH like this:
ssh -i private_key USER@OTHER-INSTANCE
Hope that helps.
Regards,
Neil

Subject: [Openstack-operators] ssh inside instance
Hi,
I’ve launched two instances from my openstack dashboard. Firstly I created
instance one, where I generated a key through the ssh-keygen command, pasting
the public key contents to import key in the access and security. Using this
key I launched second instance.
I want to be able to ssh the second instance from my first instance. Could
someone tell me how to work it out?
Thank you,
Aishwarya Adyanthaya
