Set up a ping between problem box and my workstation (on the same LAN - there is only a segment hub between the two boxes), just to see how the link behaves. See ping times go steadily from normal upwards over a period of 83s, then wrap at approx 1024ms and go down to normal, only to build up again. This pattern is consistent over a couple of hours. Put in an NE2000 clone, see problem go away. I don't know if this a problem with the driver or the single card (I've used 20 or so of these cards, and never seen it before). It is, however, interesting behavour :-) Eivind. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
