Using the 3c509 ethernet adapter, trying to set up a local net, kernel
1.3.91, I had a problem. I couldn't get the two machines on the hub talking
properly. Machine B, which I had compiled without any modules, seemed to
work fine.
Machine A, in which pretty much everything was modularized, had a
peculiarity. It couldn't talk to machine B, unless machine B's eth0 was in
promiscuous mode, in which case all it could do was ping.
I investigated the situation with tcpdump. Apparently all of machine A's
packets to machine B's IP address were addressed to machine A's physical
ethernet address. The reverse was not true; machine B, without any
modularized code, always sent packets addressed to machine A's IP address
from machine B's, to machine A's, physical ethernet address.
This was why A could ping B when B was in promiscuous mode; the packets were
addressed to the right IP, but the wrong physical ethernet address.
I am now running the same, unmodularized kernel on A as B now, and they both
talk fine. Just about all the function is compiled in. I'm enclosing the
working and nonworking .config files below, along with the script that loads
the modules that I use, and selected queries from rpm for packages I have
installed.
Anyway, the above is what I have so far. Has anyone else experienced this
problem? Alan, have you gotten reports? I am running a lowly 486DX2-80, so
recompiling things a bit at a time until they break will take a while.
