Hi List,
How do i get the bandwidth usage of a particular IP address, on
a m/c which is performing NAT?
can i use netstat? or maybe iptables?
Is there any tool available.
I tried iptraf, but its too much informative for me.
I just need to show current bandwdith usage
for 1 or more ips
Thanx,

Netfilter will help you track the number of packets & bytes sent to/from a
specific IP address, but you'll have to check the numbers at regular
intervals (eg a cron job once a minute ?) in order to convert this to
bandwidth.
Just create some rules such as:
iptables -A FORWARD -s a.b.c.d
iptables -A FORWARD -d a.b.c.d
(Yes, that's correct, you don't have to have a target to jump to if you don't
want one...)
where a.b.c.d is the IP address you're interested in, and then use
iptables -L FORWARD -n -v -x
to see the packet & byte counters.
