Hi,
I can not ping a remote host successfully unless I have "tcpdump -i
eth0" running, in which case, my network access works fine.
I am running Debian etch on a Dell Inspiron e1505 laptop. The eth0
address is static on my local LAN. Once tcpdump is running, the
laptop can access the network with no problems.
Any help or suggestions to solving this concern are really appreciated.
Thanks,
Marc

Interesting that when your interface is in promiscious mode it works
fine, but otherwise it doesn't. Do you have all of your iptables rules
cleared?

What networking hardware is on that laptop? Can you post the complete
output of `ethtool -i eth0` and the network device info from the output
of `lcpci -vvv`?

Thanks very much for your reply and interest. I find this an odd
problem. The output of iptables -L looks like:
caviar:/tmp# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
The machine name is caviar on the prompt. There are no rules in
place. AFAIK, there are no firewalls running. Changing the routing
table did not help the situation.

lspci output is attached below.

Thats correct. Its the wired interface, eth0 which is having the
problem. I have turned the wireless interface, eth2 off with both
ifconfig and ifdown, and still, the connection to the outside only
works when tcpdump is running.

The system was working originally fine, but something changed.
Perhaps through an Debian aptitude update.
Thanks for your help and interest.

Any chance you can boot back to the old kernel (the one where is was
working) and run and ethtool -i eth0 on that one to see what version of
the driver was used there? It's hard to know what may have changed
between the 2 versions of the driver since I don't know the starting
point.
It's also hard to know if this is fixed already since you aren't running
the latest upstream kernel. Downloading, building, and testing the
latest from kernel.org would be a good way to know if this is already
fixed.

I had already loaded, compiled, and tested linux-2.6.20.1. There was
no change with the newer kernel. Network connections only worked when
tcpdump was running.
Similar for booting with an older kernel 2.6.17. I think the problem
is not with the kernel, but with other system software. It could take
a while to debug, so I am just rebuilding.
Thanks for your help.
