I have an ethernet card that can send arp and icmp messages but it
won't read the responses. I can see the messages and the responses
on the network using tcpdump on another computer, which has the same
version of Linux and the same model NIC.
I installed/configured the NIC on the non-working computer AFTER
installing Linux, but the NIC was already in the working one BEFORE
I installed Linux on that one, so the installation program must
have correctly configured its NIC and its driver module.
There must be something else I have to enable or configure on the
non-working one to get it to read the messages...is there???
I know the non-working card really works because I've tried it works
in the working computer and the working one stopped working in the
non-working computer--so it must be my configuration.
The Linux is Red Hat 6.2 and the NICs are 3com 3c509b-TP
Thanks a lot.
