This script still works well enough for slower connections, but find a script for faster connections with a few more features here: /root/scripts/bwrpt.pl
#!/bin/bash
## Written by Bob Miller
## Computerisms.ca
## Last updated October 2012
## Please feel free to share this script, but please do not claim it.
## This script depends on xtables-addons, and usage of the ACCOUNT target.
## This will set up the tables we need in iptables to do our accounting. We need one entry for each lan subnet, and 0/0 is for the external address:
## iptables -t filter -I FORWARD -j ACCOUNT --addr 192.168.25.0/24 --tname lan
## iptables -t mangle -I POSTROUTING -j ACCOUNT --addr 0/0 --tname wan
## Hostname detection currently requires at least the nbtscan program, make sure that and the iptaccount program are in your PATH
## Set this program to run every hour in your crontab. Note: if you can/will exceed the IPTWRAP or NETWRAP values in the space of one hour,
## you will need to run this script more often, and adjust the TTLNOW value and routine to account for minutes instead of just hours.

#########################################################################################
#########################################################################################
## Next, we need to set up some variables to make configuration and life easy.
## Modify the following variables to your needs
## Make sure your path includes the iptaccount and nbtscan commands
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/root/scripts
## Set a comma-separated list of recipients for the daily report
ADMINML=bob.miller@computerisms.com
MLFRM=porchlian@computerisms.com
## Set the total number of internal interfaces (do not include external interface) - Valid value is any integer higher than zero:
NETNUM=2
## these are the tables you configured your --tname as. Add more NNM* variables as needed
NNM1=computerisms
NNM2=pubaccess
NNM3=
NNM4=
## For each table in iptaccount, Set the ethx interface of each port to match the NNM number (ie NNM1=IF1=ethx, NNM2=IF2=ethx)
WAN=eth0
IF1=eth1
IF2=eth2
IF3=
IF4=
## For the /sys statistics, the counter will wrap after a certain number of bits. On a 32-bit system, the counter wraps at
## 32 bits (or (2^32)-1 or 4 GB, so set it as 4294967295. on a 64-bit system, this number is (2^63)-1 or 18446744073709551615.
## Set this number for NETWRAP. For the iptaccount program, the wrap is currently hard coded to 32 bits so use 4294967295.
## If this changes, it will presumably still need to wrap at some point, so set IPTWRAP to the number it wraps at.
## Set the wrap numbers:
IPTWRAP=4294967295
NETWRAP=4294967295
## Set a base directory to hold all your working stats. Stat files will be kept here for archival purposes
WRKDIR=/root/scripts/bwfiles
## set how much data is your 100% monthly usage limit in GB (valid value is any integer greater than zero):
USAGE=90
## Set if you want Mega or Mebi (valid values are 1000 or 1024)
DIV=1000
## Totalling and reporting should happen only once per day, at the end of day.
## This is a way of only running the totals on the last hour of production.
## Set this value to the last hour of the day the script runs in 24-hour format
## Note that a report can only contain today's data, so you can't get 9-12PM on tomorrow's report
## I put this here for testing, so I could make it run at the top of the next hour,
## But it might be useful if you shut your interface or machine down on a schedule.
TTLNOW=23

## That should be all the configuration items required. You probably shouldn't modify the rest of this
## Here are more variables that we will need later.
DOIPT=$(which iptaccount)
DONBT=$(which nbtscan)
## The following variables need to be set to prevent unwanted effects:
TTLIN=0
TTLOUT=0
TTLWAN=0
STIPTIN=0
STIPTOUT=0
TMTDIPTWAN=0
TMTDRAWWANIN=0
TMTDRAWWANOUT=0

TMTDRAWWANOUT=0
TMTDIF=0
TMTDIFIN=0
TMTDIFOUT=0
TMTDLAN=0
TMTDLANIN=0
TMTDLANOUT=0
## These variables will give us a way to deal with IP addresses.
