Ubuntu Networking :: Ssh Gives Message "network Is Unreachable"

I have recently installed 10.04 on an old box I have sitting around and wanted to include it in my home network. After struggling with Network Manager I went in and set up the files manually.

/etc/hosts reads:

127.0.0.1 localhost
10.0.0.01 one.network one
10.0.0.02 two.network two

[code]....

then the IPv6 stuff

/etc/network/interfaces reads:

auto lo
iface lo inet loopback
auto eth0

[code]...

Now I can access the internet from this machine, but when I attempt to ssh to another machine in the network I get the message "Port 22 network is unreachable" Checking with google I found that there should be some ssh config files. I have one ssh_config but no sshd_config. I don't know if this is relevant. Also "network" is not the name of my network. Changed for anonymity.
