Problem pinging resources

I'm a newbie to network configuration, so this may be a very basic
problem. I am setting up a local network using Yahoo DSL. My Linux
box can't ping anything other than itself and the gateway (a
Cayman/Netopia router at 192.168.1.254). It is set up with a static
IP address. The "internal" IP address is set to 192.168.1.1 and it is
mapped to it's assigned to its external IP address by the router.
I have another computer (Windows) connected using DHCP that can access
the internet fine. It can't ping the Linux box, either.
Earlier, I was having trouble getting the default route set up, but
now that is fine.

Any ideas?

Have you loaded all the pc's ip addresses into /etc/hosts on linux?
Example from mine:
head -4 /etc/hosts
127.0.0.1 localhost
192.168.1.10 wb.home.invalid wb
192.168.1.12 wb1.home.invalid wb1
192.168.1.1 fw.home.invalid fw

You have to put the linux ip/name in windows host file. No idea where
it is.

I think you need to configure the router.

What is the DHCP assigned range of the router? If you assign a static IP
it usually needs to be in same network, but the DHCP range should be set
to less than the entire network, and any static IPs should be in the
non-DHCP range. Otherwise the router might try to assign your IP to
another machine.

Also Linux tries to find a name for any IP connecting to it, so per
another reply, you should at least have some sort of bogus names for your
other LAN IPs in /etc/hosts. Just do not use a local domain that could
possibly be a real domain, unless you own the domain (registered).

Everyone,
Thanks for the replies, I really appreciate them. As it turns out,
SBC gave me the wrong IP address range. When I finally got that
straightened out, it works fine. Again, thanks a lot!
