[LARTC] bw console monitoring

[Kristiadi Himawan]

Hi,
I want to see bandwidth every ip address in the local network that passing
my linux gateway in the console, may be it's similar like mrtg (web based
version)
It's possible ?


      Best regards,

iptraf or trafshow may help.

Yes

If you don't have to much ip addresses, you can create for each address a 
iptables rule.  You can use the byte counters of iptables to calculate the 
bandwidth.  And you can plot the data directly with rrd or feed them to mrtg.

there is also bwm.  it is very basic though. not as advanced as iptraf 
or trafshow, but it gives kbytes in and out of the interfaces.  below is 
a snipit.

        Iface        RX(KB/sec)   TX(KB/sec)   Total(KB/sec)

           lo            0.000        0.000           0.000
         eth0           52.160       64.539         116.699
       dummy0            0.000        0.000           0.000

Can it also monitor / ip-address ?

I already do that before and i have tried bwm and iptraf (nice tools with
filtering) too, but still can't do bw console monitoring for each ip
address that forwarded.
May be anyone ever try to dump byte calculated by ipchain or iptables not
to rrd or mtrg but to console ? 
Any suggestions ?

I did both.  I have script that uses ipables and generates some html or text 
output  (http://qos.dyndns.org:8080/cgi-bin/monitor.pl it's not working all 
the time) and a script that uses tc and rrd to create some graphs: 
http://home.docum.org/stef.coene/qos/gui/rrd.html.
I'm working on the second script to also include the output of iptables.

Mail me if you want to try them out and you need some help.

(I replied yesterday but my message didn't make it through somehow)

Why don't you try WIPL?  It's available from the same site as the WRR
qdisc (http://wipl-wrr.sourceforge.net/) and even though it looks a bit
beta it was able to do for me what I haven't found elsewhere.  Namely,
it took about half an hour to set it up so that it outputs a list of IP
addresses for which traffic has been seen currenly, sorted by the traffic
rate (so that the biggest downloaders are at the top). The traffic rate
is computed based on last 60 seconds' traffic, refreshed every 10
seconds (both configurable, of course).  I set wiplc to output the list
in HTML (configurable, too).  So now I have a URL where I can go to see
top network users *at real time*.  It doesn't do graphs, sure, but I use
rrdtool for graphing anyway.

The best thing is that WIPL's architecture is very modular and
extensible so you can do a lot of thing with its output (e.g. run it
through arbitrary CGI's or even store the values and graph them later if
you really feel the need).

There's one problem, though - wipld doesn't seem to age entries in its
address cache so no matter how big I set the cache, it always overflows
in the end.  I haven't gotten around yet to reporting the bug, though.
