Ok, maybe it isn't my routing table.
Netstat -r returns -I left off col heads.

192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth0
default 192.168.1.1 0.0.0.0 UG 0 0 0 eth0

In the gui for eth0 the Gateway entry is 192.168.1.1 which
is correct.
I don't seem to have a loop back entry.

Also if this helps, I am on a Static IP in my LAN at 192.168.1.51

As to my router, it passes traffic from a couple of Windoze
boxes to
the Internet just fine; you're reading this email <grin/>. The Win
boxes can ping the Linux box and the Linux box can ping the windows
boxes. What it cannot do is ping an IP off the LAN nor say a name
www.yahoo.com. I don't think this is a DNS issue yet as
like I said I
can't ping IPs off the LAN.

What am I missing here?

not sure that you are missing anything

what is output of ifconfig?

you should see lo (loopback adaptor) there

you can add dns server addresses to /etc/resolv.conf if you
want dns resolution...for example

# cat /etc/resolv.conf
nameserver 192.168.2.1
nameserver 68.2.16.30
search localdomain

you should be working just fine...

you might want to make sure that firewall isn't a problem by
temporarily turning it off...

/sbin/service iptables stop

(/sbin/service iptables start # turns it back on)

Shot in the dark - if you look at /etc/hosts, do you see the
top line with
localhost entries and your box.domain.name entries all on one
line? If so,
separate them onto two lines, localhost at the top line, then your
192.168.1.51 and system names on the second one. I find that
it saves a lot
of problems. In my limited experience gateway settings and
/etc/hosts are
the most likely causes of problems.

Only had the line 127.0.0.0 localhost.localdomain localhost
In /etc/hosts.
Adding my local IP altered nothing. Again I don't think this is a name
issue.

Ok then maybe it isn't even the Linux box in which case I am totally
confused. The Router (Linksys with DD-WRT 23 sp1 firmware) at address
192.168.1.1 is actually telling me when I try to ping yahoo's IP (not
name, IP) :

FROM 192.168.1.1 icmp_seq=0 Destination Net Unreachable

So am I right thinking this indicates the Router is blocking my packets
and if so any idea why? I know you can't see the first thing here, just
your guess. Why would Windows boxes be able (one with a Static IP like
the Linux box) be able to ping off the network and not the Linux box?
Any idea even what I should be looking for in terms of the problem?

Thanks and I hope in this case I'm not getting too far OT.
