Hi Neil, I did the same as you have suggested. I have created an instance A and generated a private_key, giving it 600 permission. Using the key I launched the instance B but when I ssh from the instance A after a while it reads:
Read from socket failed: Connection timed out I even tried with ssh –v hostname to test on one the machine outside openstack and the instance. root@new:/home/ubuntu# ssh -v new OpenSSH_6.6.1, OpenSSL 1.0.1f 6 Jan 2014 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * debug1: Connecting to new [10.x.x.x] port 22. debug1: Connection established. debug1: permanently_set_uid: 0/0 debug1: identity file /root/.ssh/id_rsa type -1 debug1: identity file /root/.ssh/id_rsa-cert type -1 debug1: identity file /root/.ssh/id_dsa type -1 debug1: identity file /root/.ssh/id_dsa-cert type -1 debug1: identity file /root/.ssh/id_ecdsa type -1 debug1: identity file /root/.ssh/id_ecdsa-cert type -1 debug1: identity file /root/.ssh/id_ed25519 type -1 debug1: identity file /root/.ssh/id_ed25519-cert type -1 debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_6.6.1p1 Ubuntu-2ubuntu2 debug1: Remote protocol version 2.0, remote software version OpenSSH_6.6.1p1 Ubuntu-2ubuntu2 debug1: match: OpenSSH_6.6.1p1 Ubuntu-2ubuntu2 pat OpenSSH_6.6.1* compat 0x04000000 debug1: SSH2_MSG_KEXINIT sent Read from socket failed: Connection timed out So this is what I’m getting again.

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.

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?
