ethernet at half duplex

acid_kewpie · 09-12-2001, 05:02 PM

My two ethernet cards on my gateway are both running at half duplex only.

demsg | tail says:

eth0: Setting half-duplex based on auto-negotiated partner ability 0000.

the leds on both cards are permanently off.

anythign i can do to bring my network back to a useful thoughout?

is it any likelier to work with a nice new fresh distro installed? (i'm looking for reasons to put MD80 on my gateway instead of rh71...

Are they connected to something running full duplex? Like not a Hub

If so I'm all out of ideas

well i had one card at full speed, but then i added a second indentical card to the machine, and both run at half now... even when i take down one interface

To echo Q25 - they are on a switch or two cross-over cables yeah?

Sorry.. yes it's two separate cables,*two NIC's and a different single machine at the end of each one.

Uhm... Stranger and stranger...

What are the two cards? What Kernel you running? Post the contents of /proc/pci , /proc/interrupts & /proc/ioports maybe it'll give someone a hint. The other thing you might want to try doing is reading up on the code for you NIC and seeing how to force full-duplex, the driver may just default to half-duplex if more than 1 card is present for some strange reason (maybe just to confuse people!!

)
