[ubuntu-cloud] Can't SSH into instances with certain IPs

[Andreas]

Hey guys,

I have a problem with SSHing into certain instances..

In our Cloud we have 2 public IPs available:
- XX.XX.XX.98 and
- XX.XX.XX.75

Here is the problem:
- When an image gets started with IP XX.XX.XX.98, I can SSH into it.
- When the same image gets started with IP XX.XX.XX.75, I CAN't  SSH 
into it. I get an "access denied" SSH error.

Does anybody have an idea what is wrong?
- I can ping both IPs without a problem..
- euca-get-console-output also works for instances running on any of the 
2 IPs
- I used euca-authorize to enable tcp and icmp for IPs 0.0.0.0/0 on port 
22 and 3389



THX
