sharing cable modem connection using router

I have two computers which are dual boot windoze 98 and Red Hat Linux 7.2. They are each connected to an ethernet hub which is connected to a cable modem router. The router is then connected to the cable modem of course.

In windoze, they are aware of each other and can share files, printers, and anything else that I want.

However, in linux, neither can ping the other.

Both computers are using DHCP and can access the internet simultaneously.

When we installed linux, both machines had the default hostname localhost.localdomain.

I used the "neat" utility to change one of the hostnames, so that I could use the hostname to find the other machine (or so I hoped).

My question is this. What do I need to do to enable these two computers to ping each other, share files, etc?

1. find out what IP's your router is giving you when you use windows. Use winipcfg for win98/me and ipconfig for NT/2000 dont know what xp uses. write down all the info: IP address, name server address(DNS), default gateway. (default gateway for linksys is them down
2. Boot up into linux, and run netconfig or linuxconf if you installed it.
3. netconfig: type netconfig in console, and it will bring up a window, dont select "use dhcp" instead enter the ip that the router was giving windows or you can use one that is in the same range ie; if your router was giving out you can use any through next put in the netmask default is Next default gateway, this is the lan side of your router, default for linksys is Next is name server(DNS), When done click ok, and it should restart networking, if it doesnt work try rebooting.

I find that i have less problems when i put everything in static.

How about the other computer on the network

How do I allow internet access for both computers using this plan? Do they each have a different address in windows? (I haven't checked yet) If not, how do they communicate with each other?

It works

Just for anyone esle who is trying to do the same thing.

The IP address given by winipcfg was different for each computer on my lan, so I manually set each computer.

By the way, the IP addresses and gateway looked pretty generic, so if anyone needs to do this and does not have windows installed, try these IP addresses (they come from the pool of local addresses which wouldn't be valid as public addresses)

first computer:

second computer

if I had more, I could just add them following the same pattern

the network mask is

and the gateway is
