[NBLUG/talk] Network problems

[Jack Smith]

When I initially installed Fedora 8 I had this same problem.  Unfortunately,
I just kept poking it until it worked and have no real idea how I fixed it.
Because I want to try Xen, I booted off the Xen kernel and the problem is
back.  (with that kernel)

I can ping anything on either network, eth0 or eth1, but I can't ping
anything on the other side of my linksys router which is supposed to be my
default gateway.

Here is the ifconfig and netstat output from the regular kernel, which
works.

ifconfig -a

The Xen kernel looks exactly the same, except the ifconfig command also
shows a peth0 section that looks like this

 peth0 Link encap:Ethernet HWaddr 00:17:31:01:C8:A8

inet6 addr: fe80::217:31ff:fe01:c8a8/64 Scope:Link

UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

RX packets:53 errors:0 dropped:0 overruns:0 frame:0

TX packets:121 errors:0 dropped:0 overruns:0 carrier:0

collisions:0 txqueuelen:1000

RX bytes:5414 (5.2 KiB) TX bytes:14547 (14.2 KiB)

Interrupt:18


Any idea what I should try next?
