ipaccou is a *nix-based program developed to collect consumed network traffic passing through Cisco-based router.
The information is kept in a structured way in a textual form and presented per days, months and years.

Here are the complete and detailed steps to get it working:

1. Enable rsh server on a router and specify the IP address and user of this machine in terminal configuration shell, e.g.:
   Router#configure terminal
   Router(config)#ip rcmd rsh-enable
   Router(config)#ip rcmd remote-host root xxx.xxx.xxx.xxx root enable

2. Edit ipaccou.conf configuration file.

3. Enable IP accounting output-packets on a desired interface of router:
   Router#configure terminal
   Router(config)#interface f0/0
   Router(config-if)#ip accounting output-packets

4. Edit crontab file to run ipaccou when necessary. Also it is needed that a current working directory should be
   given as a command line argument in crontab entry (e.g.: /home/avdav/ipaccou/ipaccou /home/avdav/ipaccou).
   When specifying a large amount of time interval in crontab, make sure if there is enough quantity
   of entries in the accounting database of the router. It is recommended to set ip accounting-threshold
   (512 entries is by default) to 32768 entries, e.g.:
   Router#configure terminal
   Router(config)#ip accounting-threshold 32768
