I've tried three or four different cables, all gave about the same performance, and I still see increasing Oerrs (more like 25%, actually) every time I FTP from the BSD machine. The machine is home-assembled based on an Asus P2L97 with a K6-200 and a Netgear FA310TX PCI netcard. For historical reasons, I've got a Kingston netcard sitting in the machine as well; tomorrow I will try rearranging the ip configuration to use that interface. (I tried this with and without the Kingston driver linked in the kernel, but haven't tried switching to use it.) I should probably pull extraneous cards as well... I should have probably exhausted such things before mailing the experts; as a bsd newbie, I was hoping there was a "oh, yeah, that's almost always X" type answer that I couldn't find in the faq or archives. Sorry if that's a nuisance. Thanks for the help, and if you think of anything else, please let me know. ...Craig To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
