FTP transfers are generating a lot of collisions. The network is 10baseT/UTP. If i use the machine as the client to upload stuff to a local server, the throughput is around 1.1Mbyte/s, but I get 700 collisions/seconds. On download, it's half that number. Note that the upload collision count is around 50 on Windows (the machine is dual-boot), and this is the primary reason why I target the driver as responsible for this behavior. I tried changing the wires, without any luck. >How-To-Repeat: I'm fairly confident that the card is responsible for this behavior. At least the driver for the card, as Windows doesn't show this behavior. So: 1- build a box with this card in it 2- connect it to another box (an ftp server) using a crosslink wire, or a hub 3- try an ftp upload or download A side effect of this problem is that when I hit 700 collisions/second, I can hang the network on the server. The server is a small machine (P166 w/ 64M ram), but I still don't get how it can freeze. All other functions are unaffected on the server. >Fix: Unknown. For the side effect, a workaround is to ifconfig down/up the faulty interface. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
