After ifdown, ifup my interface i see packet arriving in it but...

while using tshark to catch packets, here is what i get when it runs :

tshark -i eth0
No log handling enabled - turning on stderr logging

audit(1196968132.562:2): dev=eth0 prom=256 old_prom=0 auid=4294967295
Capturing on eth0

And nothing...

To correct what i wrote earlier.
Pci export from Dom0 (Debian Etch) to DomU (CentOs 5) works.
I can transfer big files but after a moment, no response (while not using it)

Could it be acpi that standby my card which do work correctly?

Thanks in advance.

Hello everybody,

I've finished with pci export from DomU to Dom0 (Debian Etch) but now i have a new problem, and a big one.

My ethernet card is dropping packets but after some time (i can't tell how)
It can work for a day (not in production so not hard tested) and then all packets are dropped.

Look at the ifconfig output :

eth0      Link encap:Ethernet  HWaddr XX:XX:XX:XX:XX:XX
          inet addr:  Bcast:  Mask:
          inet6 addr: fe80::213:72ff:fe0f:1c6a/64 Scope:Link
          RX packets:10505 errors:0 dropped: 352 overruns:0 frame:0
          TX packets:2921 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:2223312 (2.1 MiB)  TX bytes:555445 (542.4 KiB)
          Base address:0xcce0 Memory:fe3e0000-fe400000

Today, nothing was done on it but, a few minutes before, i realised that it was down.

Dmesg output :

The interface is still up.

I saw while googling that it could be an hardware problem but this was not in a xen environnement so...

Anybody have seen this before?


Best Regards.
