static home-network IPs and Ubuntu Server

OK, so I installed Ubuntu Server 8.04 LTS in Parallels (latest build) on Tiger (getting Leopard shortly). I want it as a development web server, but I'm still learning Unix (this is very much for educational purposes). My goal is to have it have a static IP address on my local network such that the host computer (a Mac Pro) and my laptop (a MBP when the new ones come out) can have a simple hostfile entry for it. I'm trying to set up the same on my Mac Pro. I have two complications:

1) I'm stuck in rural Virginia without Internet until mid-August.
2) I don't have an X-server (being a headless server), so I can't install Parallels tools.

I can set an IP alias on the Mac and on Linux, but how do I convince them that they're networked together? They both check my Ethernet port, realize there's nothing plugged in, and drop a "no route to host". And once I get that working, how do I bridge it such that anyone connected to my Mac Pro over Airport or Ethernet can reach the VM?

Thanks in advance for any help.
 
Did you try shared networking?
Also please let me know output from Mac OS and Ubuntu

ifconfig -a

Please note, that for now Ubuntu 8.04 doesn't support Parallels Tools
 
OK. Do I need to get a network driver from elsewhere then?

Unfortunately, I'm at work (no internet access from my computer at home), so I can't copy-paste the ifconfig results.

I can successfully set up eth0 and en0 with an IP alias (so I have an inet: entry in ifconfig), but they still won't find a path to each other, even though they're on the same subnet.
 
I've tried both Shared Networking and Bridged.

I can get the OS X and Linux sides to get the right IP addresses, so the issue isn't an ifconfig one.

Linux: eth0 inet: 172.16.12.102
OS X: en0 inet: 172.16.12.101

The issue is that even though they're on the same subnet, they don't have a route to each other for some reason. Why would I even need routing on the same subnet?

I've tried switching adapters and even plugging a cable between my two Ethernet ports, to no avail. I will probably have to pony up for a router...
 
1. Disable firewall in Ubuntu and Mac OS
2. Set Network adapter in Ubuntu to manual by DHCp
3. Try Shared Networking

Another way
if bridged Ethernet
Set default adapter
and if you are using Ethernet from Mac to access Internet use that IP range if Airport in that range (if by DHCp using Airport use manual DHCP)

What's the /etc/network/interfaces code to do that? I switched back to DHCP on the Linux side, but I don't know how to do DHCP with a manually configured address.

I tried using Bonjour/avahi-daemon, and I can ping the Mac from Linux, but not vice-versa
 
Try this

save content between lines in file /root/empty

then

iptables-restore < /root/empty

For current session there is no firewall in Ubuntu
