4.2GB/minute? Tasty.

James is? I thought FreeBSD was doing the counting? :)

This machine is the box sitting in front of my single user LAN connected
to a cable modem:
tcp:
11962790 packets sent
7754863 data packets (3000140145 bytes)
12199847 packets received
5346910 acks (for 2999095921 bytes)
8383470 packets (4099500609 bytes) received in-sequence
320301 out-of-order packets (423292462 bytes)
It's been up for 25 days, and every single one of those byte counters is
totally bogus (well, *maybe* sent is accurate, received cetainly isn't, or
won't be very soon).
I'm just interested in how much bandwidth I'm using, but if the counters
are going to overflow this easily, they cease being terribly useful,
unless I'm going to actively count them and watch for overflows in
userspace.
I'm not really bothered if they're totally accurate, since they're just
a guide - how about a float that counts kb? ;)
