[MLB-WIRELESS] Tracking usage when sharing broadband?

[rick]

look as for all this goes
ima  cable user

i am not going to share my access to total strangers, but if you ask me i will give you 4 or 5 hrs access

as for my friends they will give as much access as i can spare, except when im playing dark age of camelot or something else that i require all my bandwidth

in linux its quiet easy to set max bandwidth to a ip you are shafreing to

i got shown how to today

and we wont limit melb wirless to cable/dsl users cous thats just silly

this isnt a eliteist club, its a comunity

what people put in is what they get out its that simple

or maybe it isnt

:)

        Hi All,

        Instead of measuring in a forwarding rule... Perhaps just an input rule on the interface connected to the adsl/cable connection. As then you are not counting the traffic between the other tenants. Coz if u play games etc or have other comon resources that u share, it will all count & u r not sure who has actually used the common cable bandwidth.

        Ciao,
        Dave

        cool.

        depending on how things are set up, this could be easy (or not).

        Bruce> And which router is recommended for this purpose (ie. which

        i use a linux box, with iptables. you can define accounting rules
        pretty simply -- my setup has:

        /sbin/iptables -A FORWARD -i eth2 -d 10.0.0.129
        /sbin/iptables -A FORWARD -i eth2 -d 10.0.0.130
        /sbin/iptables -A FORWARD -o eth2 -s 10.0.0.0/8

        (ie. one chain for machine of interest, plus a common upstream chain)

        and i can report the current totals like

        iptables -L FORWARD -v

        which gives 

        Chain FORWARD (policy ACCEPT 1114K packets, 553M bytes)
        pkts bytes target prot opt in out source destination
        23444 16M all -- eth2 * 0.0.0.0/0 10.0.0.129
        154K 115M all -- eth2 * 0.0.0.0/0 10.0.0.130
        558K 57M all -- * eth2 10.0.0.0/8 0.0.0.0/0

        right now.

        i think the raw bit rate, in one direction, is 11Mbps. but you won't
        see that in ftp due to various protocol overheads. through the
        reinforced concrete of your average apartment block, you might ahve
        some trouble with getting 11Mbps working too (ie. it might fall back
        to 5.5 or 2 or even 1).
