when adding a new box to a ethernetwork I encountered some problem
that looks to me like a hardware problem:
The network: used to consist of two linux boxes with ISA ne2000
cards and 10base 2 cable. It used to work fine (and still
does for those two boxes).
The nex box: has a rtl8029 (ne2000 compatible) PCI card. It is running
a SUSE 6.0 Linux with the included 2.0.36 kernel included.
The symptoms: the card is correctly recognized by the driver, ifconfig
works as I expect and shows me
eth0 Link encap:10Mbps Ethernet HWaddr 00:E0:7D:50:29:FA
inet addr:188.8.131.52 Bcast:184.108.40.206 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0
TX packets:18 errors:0 dropped:0 overruns:0
Interrupt:11 Base address:0x6300
what looks fine to me.
Now what looks wrong?
- there are two LEDs on the card, one to show I/O traffic and
one to show `network connected' (LED on) or `network disconnected'
(LED off). And this second LED is allways off.
- when I try to ping another box in the network, the number of
transmitted packages slowly goes up, but ping gets nothing back
Ping claims to have transmitted a lot more packages than
the statistics from ifconfig or netstat -i
- arp -a prints instead the ethernet address of the pinged box
- the LED on the card signalling traffic indicates no traffic
The included diagnistics software for the card finds no errors when checking
the cards components. Unfortunately I cannot test the network conection
with this software because this needs two boxes running the software; but
this software detects unplugging the cable.
I used two different cables and exchanged the T-connectors between the
ethernet cards of the three boxes without changing the symptoms.
Well this looks to me like a hardware problem but I would like to be sure
before going back to the dealer... Is there any other possibility?
Thanks a lot for any help!
