[HLUG] bandwidth logging

[Steve Bushell]

Completely agree with speedtest.net, as for samknows, they are 'usually' reliable, but in the wilds, it can go very wrong!

This is what speedtest.net gives me 'now' (a typical tuesday night, quiet with me, but who knows what joe public is doing just up the road... 1 mile from the exchange)

5.75 Mb/s down, 0.37 Mb/s up  and  78ms latency... it gets better, but that's 'now'.

Netstat will show any open connections, but that'll only be on a pc by pc basis, but if you are 'that ' close to the limits, you're fighting a lost battle - isn't tonight a 'huge' Microsoft update night?

Well you have to install it onto an old pc, but wireshark or using router stats is probably just as good if not better suggestions

also try speedtest.net to get an idea of the real speed you can achieve. I think samknows is a bit wrong in this instance, as I have measured about 3.5 MB/s with a 5km long line length, and I'm only about 1/4 mile closer to the exchange than you
