internet (without LAN) monthly traffic statistics

[Dj YB]

hello,
does anyone know of a good (working) program for monthly internet usage stats
I need this info to stay under my monthly traffic cap.
I am using a single ethernet connection for LAN and internet.

iptraf is really complicated and require too many changes,
vnstat doesn't support the separation using single interface...
any help on this matter will be greatly appreciated.

using Fedora 11 KDE 4.3.2

I won't be able to read emails in the next two weeks so no rush :-)

thanks,
YB.

If the NIC sees all the packets you can get a rough approximation:
  iptables -I INPUT ! -s 10.0.1.0/24  #<- your LAN net address here
  iptables -I OUTPUT ! -s 10.0.1.0/24 #<- and here

run that at the start of the month, then
  iptables -L INPUT -nv | head
  iptables -L OUTPUT -nv | head

would give you the packets and bytes sent to (received from) non-local IP 
addresses. Ugly, inconvenient, must be started at the beginning of the month, 
data lost on reboot, all of which you could hack around with clever scripts, but 
there must be a better way.

The better way is probably MRTG or similar, which are complex to install, then 
work well and do what you want. I'd skip iptables, it's pretty ugly and high 
overhead to do right.

If the problem is sorting out which traffic went through the pay 
connection, perhaps IPTables could be used.  Just an idea...

I would hope that you have a firewall between your LAN and the Internet, and 
could have it keep track. Any packet sniffing program would be more complex and 
less effective, and if you use a switch it won't see all packets anyway.

Doesn't your ISP have a current volume status page? Many ISPs wo have a cap make 
that available.

Cacti is good at this, and I think MRTG can do it, too. But neither of
those is simple to set up. I'd give them a try, though, you might do
OK.

Depending on exactly what numbers you need, NTop is also a
possibility. It's dead easy to set up, and it's capable of breaking
out separate interfaces. The level of detail will be enormous, but
it's actually (IMHO) much easier/faster to get running than either
Cacti or MRTG.

If you're good with any scripting languages, you might want to
consider just polling the kernel's interface counters, yourself, via a
regular 'cron' job. That might not be an option, though, depending on
your skill level.

thanks all.
my ISP is my university and I can't replace it
there is a volume page but it is not updated most of the time, and it requires 
login and browsing, and it is not reliable, many mistakes...
the internet\lan are on the same interface so the seperation must be ip 
address based.
from what I could understand about MRTG and Cacti sites, this programs use 
SNMP.

If his ISP is counting packets that get dropped before they get to
is end of the local loop he won't have a way to know.

If his ISP isn't providing him this information easily, but still planning
on doing bad things if he exceeds the limit, he should be complaining to
the ISP and possibly trying to find another one.
