No IP address in container and cannot SSH into containers

I'm having problems getting my first few containers set up right.

I have Ubuntu 12.04 and Debian 6 containers running from built-in templates. I have managed to get the Proxmox console to work eventually by installing Oracle Java and following these directions.

However I cannot paste into the Proxmox console and it seems pasting is not yet implemented.

So I want to SSH into these containers. One of them registers on my internet router but only one and I can't tell which it is. SSHing to that IP results in a 'connection refused' error.

openssh-server is installed on both containers verified by executing 'apt-get install openssh-server' on each container. Both return 'the installed version is the most recent'

When I run ifconfig on both containers from the Proxmox console they both show they only have a local loopback device running, no eth0. I assumed they would both pull IP addresses from the local router by DHCP. They were both set to their respective vmbr0.

I am a bit stumped as to how to get this all working.

I want to give them static IP addresses really, and to SSH into them both.

Thanks for any help in advance.
