Hello,

This is an office environment where client's PC are connected with a hub and that
hub is connected with the gateway debian box. How can I monitor the bandwidth at
the gateway server to check which sites are eating maximum bandwidth. I have used
iftop / ntop etc..... but still unable to get the proper report i.e. when I visit
youtube or do a torrent download from my own client box; I can't see the presence
of those connection through iftop / ntop. Could anyone suggest a proper tool
for this ? Or am I missing the right technique needed for
iftop etc ?

Thanks

iptraf is a nice tool if you don't need to collect data.

Well... the objective has some more depth :-)

I like to know the bandwidth eater as well as to know the LAN IP which request that site.
Say youtube or torrent download is eating the bandwidth and I like to know the IP which is
taking so much bandwidth by using those services. I have got some hope through iftop but still
not upto the level of my requirement. jnettop and iptraf are also there but not that much
helpful like iftop.

So any suggestion in that direction is very much helpful.

Thanks

Hi !

You should see interesting things with Ntop. If not, perhaps your
client don't really go through your gateway ?


Concerning Web traffic, if you really want to see URL usage, you should
use a proxy server and a log analyser.

I use squid + lightsquid and I'm quite happy with them.
Of course, you need to configure the clients, or use it as a
transparent proxy...

Yes, ntop is always exciting. But in my debian box the browser view shows

[..........]

Please enable make sure that the ntop html/ directory is properly installed

Error 400

The specified request is invalid.
Received request:

"GET / HTTP/1.1"

[........]


I then start ntop from command line ( stopping the deamon ) . And got the error as

[.....]

**ERROR** RRD: Disabled - unable to create base directory (err 13, /var/lib/ntop/rrd)

[....]

So I executed as root

chmod -Rvf 777 /var/lib/ntop/

That permission error has gone but same problem when visiting browser. And now I have


[...]

EPIPE while sending page to web client (skipping further warnings)
WARNING** packet truncated

[...]

Any clue ??

It tells you about all traffic through the device.

Or Munin. Of course, Munin builds stat graphs for everything, including
the kitchen and bathroom sinks and those of your neighbors. Very
thorough. Maybe too thorough for some.
