Ubuntu Server etc/network/interfaces Fail

[UbuntU-ME]

I have a windows box with Windows XP. I have an old box which i decided to setup with Linux and use as a Samba server for sharing files with my Windows box. I do not use this computers to connect to the internet. I use internet only on my laptop. Well i went forward and installed ubuntu 7.04 server [as the box was old for ubuntu 9.04 server]. Everything went well, I had to install samba manual and got some dependency files from the internet. Now everything was setup perfectly. I assigned the ubuntu box with static IP 10.0.0.1 and for the windows box the ip was 10.0.0.2

The ubuntu box config :

auto eth0
iface eth0 net static
address 10.0.0.1
netmask 255.0.0.0
network 10.0.0.0
broadcast 10.0.0.255
gateway 10.0.0.0.1

Now i did appropriate configuration on my windows box. I pingged windows box from ubuntu and vice-versa and it worked. But when i restarted the network session, i got this error :

/etc/network/interfaces :6: unknown address type ifdown : couldn't find interfaces file "etc/network/interfaces unknown address type ifup : couldn't find interfaces file "etc/network/interfaces" FAIL

Can anyone tell me, what to do? Please help!

Try this :

auto eth0
iface eth0 inet static [it should be inet, you wrote net]
address 192.168.0.1
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.1

Yeah, that right, also as you are not connected to internet, you don't need gateway, just leave it blank... You will need to configure the samba's config file [smb.conf] according to your needs. All the best...
