AFAIK it's not even a proper standard. If you don't configure statically you get mismatches and then collisions... You can't really configure full duplex on a hub... well if you could it would be a switch. That brings us to the next point that many switchs don't have interfaces to set the switch side to full duplex so you're stuck with auto-negotiation. And the only thing more broken than auto-neg is setting one side and not the other. And finally many network drivers don't support setting full duplex when the driver is loaded so you're stuck tryiing to run something in rc.local... assuming ethtool or mii-tool supports the card and many cards aren't supported. In summary, doing away with auto-neg does tend to solve the problem, but there are significant barriers to doing this in many enviroments. kashani -- gentoo-user@gentoo.org mailing list

Frank, You are not supposed to statically configure hubs and switches. I don't know what the problem is - however, please be sure that the hub/switch is set to auto-sense. If you cannot get a connection established that way, please try the cable etc. I would also recommend following the other suggestion of emerging the later tools. thanks, joshua p.s. A fellow at Cisco last year wrote an article about NIC negotiation. Apparently the only setting that consistently works is auto.

I missed that in the original email. Linux more so than Solaris, which isn't that great either, seems to go out of it's way to get the wrong setting when you hard set a switch port to full duplex. Don't know if that's a switch thing or a Linux thing. Setting auto negotiate works best these days though there is quite a bit of documentation that says the opposite from 4-6 years ago when that wasn't always the case. kashani -- gentoo-user@gentoo.org mailing list
