It sounds like you might have a bad cable segment. Yes, on looking, it was generating a lot of errors. Taking this idea, I swapped cables with the other machine on my desktop -- a Mac. Now, an interesting thing: this same 'bad' cable was being used without problem from a Mac running variously MacOS and MkLinux. When I swapped cables, the difference was like night and day on the FBSD box. OK, so I tested the 'bad' cable on my Mac... 0% packet loss, FTP speeds of 700 k/s (which is what I normally expect). I presume from this that the intel hardware is not as uh, something. Sensative? forgiving? whatever. Wierd. +C -- Thinking of purchasing RAM from the Chip Merchant?
