Setting up a simple network

Message

I am trying to set up a simple network between a few computers.

I have connected the hub to two PCs, and configured the two with static network settings.

IP: 192.168.0.2/3
Broadcast: 192.168.0.7
Netmask: 255.255.255.248

But they can't communicate with each other. I have tried other network settings; I even configured a DHCP server on one of them, but they simply can't find each other.

What do I need to do? I don't need Internet on the network; it is simply for playing games.

First, not that it should matter that much, do you really have hub or a switch?

When you say they cannot find each other, do you just try ping each other or what do you do exactly?

I connect both PCs to the hub, then I put the network settings in /etc/conf.d/net, run /etc/init.d/net.eth0 start and then make the PCs ping each other, but they never get a response, only 'destination host unreachable'. I have tried specifying the interface with the ping -I option.

Can you post the output of /sbin/ifconfig from both machines?

Are you sure both machines are plugged in properly? (and are you sure that you didn't do something dumb like plug one into the uplink port or something)?

Did you check the output of dmesg or tail /var/log/messages for anything suspicious?

Ehh . . . I had forgotten that one of the PCs had two wired network cards . . .
Sorry, I feel like a complete idiot.

Now I am trying to configure one of the PCs as a router to supply the wireless-provided Internet to the rest of the network.

eth0="192.168.1.1 netmask 255.255.255.0 broadcast 192.168.1.255"

/etc/dhcp/dhcpd.conf
ddns-update-style ad-hoc;

subnet 192.168.1.0 netmask 255.255.255.0 {
option routers 192.168.1.1;
option subnet-mask 255.255.255.0;
option domain-name-servers 217.13.4.24;
range dynamic-bootp 192.168.1.16 192.168.1.253;
default-lease-time 21600;
max-lease-time 43200;
}

I have connected the router machine with a two-way cable to the hub's uplink port, but the other PC does not get a DHCP response.
