Request help with simple network

I am trying to network two Redhat systems to share the internet
connection and hopefully files and the printer. There are two machines
direct connected via a crossover cable.

Machine Galileo in the basement runs RedHat 9.0 (updated through Dec
24,2003) and has two ethernet cards. eth0 gets its address from the
cable modem via DHCP. This was set up with the gnome gui "Internet
Configuration Wizard". eth1 is connected to machine Fermi. It's address
is fixed at 192.168.1.1

Machine Fermi on the first floor runs RedHat 7.3 (P-133 with 2 Gig drive
and 64Meg RAM). It has one ethernet card. eth0 address is fixed at
192.168.1.2

Both machines have their /etc/hosts set as follows:
127.0.0.1 * localhost
192.168.1.1 * galileo
192.168.1.2 * fermi

In addition, Galileo has an entry set by DHCP that varies each time the
cable modem is booted.

The following commands work on both machines:
ping 192.168.1.1
ping 192.168.1.2
ping fermi
ping galileo

"ping www.google.com" works on galileo but not fermi. Likewise mozilla
connects to the internet on galileo but not fermi.

I think I need a route command on fermi, but something is wrong with the
syntax that I am using. I tried the gnome gui "Internet Configuration"
trying both "use DHCP" and "192.168.1.2" for IP addresses.

One more thing, Galileo was installed with "medium security" (default)
and fermi has been added as a trusted host. Fermi (the uncommunicative
machine) was installed with "no security".

Please help me set up basic internet connectivity on fermi. Any hints
for file/printer sharing would be appreciated too. I have seen many
setups via google, but often the files given to edit do not exist on
either machine.
