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?
