Here's the output from ifconfig for eth0:

$ sudo ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:02:3F:7C:AC:CB
inet addr:66.30.27.46 Bcast:255.255.255.255 Mask:255.255.248.0
UP BROADCAST NOTRAILERS RUNNING MULTICAST MTU:1500 Metric:1
RX packets:7187105 errors:0 dropped:0 overruns:0 frame:0
TX packets:55 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
RX bytes:431229374 (411.2 MiB) TX bytes:10268 (10.0 KiB)
Interrupt:11 Base address:0xd000

How can I determine the reason behind the large disparity between
RX and TX packets?

FWIW, I'm using Debian stable.

Many thanks in advance,

How are you using your eth0 connection? I would guess that you are
not running a web or ftp server, or sending much mail.

Do you think they should be equal ?

Do you think they should both be zero ???


Do you have any problem with the ethernet connectiong ? you havent used it
much, what happens if you use it ?



Because you havent used the interface, but there are a lot of packets
received, there are two guesses I can make,

1. if the computer was up for a very long time (week or more), maybe its
just the broadcasts off other computers.
2. if the computer wasnt up for such a long time, maybe its got a ethernet
sniffer running, and that put the etherent card into 'promiscuous mode' .
Its receiving every packet off the ethernet.
