measure throughput?

Hi

I have a linux firewall. I would like to measure how much data (all
data icmp tcp udp) is passing through this machine.

what i want to know is my internet uploads and downloads. Can any one
reccomend software that can do this on the linux box??

cheers David

If you want to meter the TCP packets, for example, you can create
a new chain called TCPMETER and send all the data to that chain,
then in the chain you just add a single rule with an unconditional
RETURN. You just read the counters for that rule and you are done.

I'm partial to xosview for measuring instantaneous rates. You can use
several online tools to measure average throughput - one is at
dslreports.com.

Personally the one I like most, from some xterm:

sudo iptraf

Thanks Jose

what does this look like (assuming eth0 is outside interface)??
also how do i view the counters??


iptables -N DOWNLOADS
iptables -A INPUT -i eth0 -j DOWNLOADS
iptables -A FORWARD -i eth0 -j DOWNLOADS
iptables -A DOWNLOADS -j RETURN

iptables -N UPLOADS
iptables -A OUTPUT -o eth0 -j UPLOADS
iptables -A FORWARD -0 eth0 -j UPLOADS
iptables -A UPLOADS -j RETURN

thanks
Dave

Yes, that's what I do. Then you can use iptables -L UPLOADS -xvn
to get the counters and you can use bash or perl to extract the
counters from the output of iptables.

If you are gonna use a lot of this kind of chains and you want
to check a lot of counters you better use a C program using
libiptc to check the counters, or it will be very slow.
