SSH to VM failed

Sorry I write it too quickly.
I manage to create a VM with OpenStack.
I add the rules for ping and ssh on OpenStack.
There is a client SSH on my VM.
But the ping is ok but not the SSH.
I don't have any clue where is the problem, I can send you the nova.conf or all my config s network...
I try with or without RSA key =/

I try this too :
# killall dnsmasq
# service nova-network restart

Can you help me ?

Did you create security group to allow ssh connect?
example:
nova secgroup-add-rule openpub icmp -1 -1 0.0.0.0/0
nova secgroup-add-rule openpub tcp 22 22 0.0.0.0/0

yes I add it in the dashboard and in command line, but even without icmp rules I can ping my VM.
Maybe there is a problem of settings, I don't know.

what is the console output when you ssh to the vm?

it is this one :
test@one-PC:/usr/lib/ltp$ ssh -vvvv 172.16.0.3
OpenSSH_6.0p1 Debian-3ubuntu1, OpenSSL 1.0.1c 10 May 2012

debug1: connect to address 172.16.0.3 port 22: Connection refused
ssh: connect to host 172.16.0.3 port 22: Connection refused

do you create keypair using keypair-add and using that keypair to boot your instance?

I create the keypair, add it to the VM and try to ssh but it failed and it didn't talk about rsa key.
I go to the VM and the ~/.ssh/authorized_keys is the same as mine.
I try to telnet but it failed too.
I try different port but nothing better.

Thank you very much it was all my fault...

There was a ssh client but no ssh server

hello kaabache

I faced the same question with you. Could you tell which server don't have a ssh server?

Thanks!

My VM didn't have ssh server on it.

hi kaabache

Thanks for your reply.

When i create a ubuntu instance , i can't log in it in dashboard. so how do you solve the ssh server problem?

sorry, i am a fresher.

Thanks again!

Hi Edward,

If you want to log in throw the dashboard, it s a VNC connexion normally and not a ssh connexion. VNC is more about the openstack configuration.

If you want to ssh your server you need to install ssh server on your ubuntu instance. you can install it with an iso that you add as a CD driver. I ve never done that so I can check it.
