David,
I am fairly sure that I have ruled out this problem . I have tried
different cables, different sockets in the wall and different ports in
the switch. I have tried different ethernet cards.
The cables were factory made.
I have a working Red Hat Enterprise 3 Linux system sitting next to it.
I've plugged that ethernet cable into the FC3 system. The FC3 system
still fails.
I replaced the FC3 OS with RHE3. When RHE3 was running on the same
hardware, I didn't experience the problem.
Is it possible the drivers included with FC3 are more sensitive to
hardware issues, than RHE3 linux?
Thanks,
Keith
