- IPacc v0.1
- Using IP accounting kernel rules to feed mrtg.
- 1. Abstract
- I am using the old ipfwadm style for doing this for backwards compatibility,
- and because it's enough for my purpose.
- For those who have kernels higher than 2.0 (using IPchains), like 2.1 or 2.2.
- I have included the ipfwadm-wrapper by Paul Russel.
- So if you if you are running on 2.2 (like me), you should copy this to
- /sbin/ipfwadm.
- It's a little slow, but it's done with sh.
- With this script you may generate trafic grahs for any IP, any networks or subnetworks.
- I haven't done support for icmp prot.
- 2. Syntax
- You use the exact sintax as with ipfwadm
- ipacc [mode] [-S source_ip/net_bits [port1 port2 ...]] [-D dest_ip/net_bits [port1 port 2 ...]]
- where:
- mode - is either "in" or "out", if you don't specify any there will be
- included 2 rules in this fashion:
- in -S source_ip/net_bits sport1 sport2 -D dest_ip/net_bits port1 port2
- out -S dest_ip/net_bits dport1 dport2 -D source_ip/net_bits sport1 sprot2
- source_ip & dest_ip - are the dotted ip address of the source and the
- destination (IP address not hosts)
- net_bits - are number of bits used by the network+subnetwork if any
- (that is 24 for a whole class C or 25 for half a C class ...)
- you don't have to specify any if you are doing it for a host
- portN - the ports where the packet it comming from and is going to
- 3. The printings
- If you are using one way
- ipacc will print
- inbytes, 0, uptime, server_name for an "in" mode rule
- or
- 0, outbytes, uptime, server_name for an "out" mode rule
- for both ways (in - out)
- it will print
- inbytes, outbytes, uptime, server_name
- inbytes, outbytes - the numbers read from the ipfwadm command
- uptime - is what the uptime command will print
- server_name - is what you'll write at the server name in the script
- So you will add something like
- Target[ipaddr]: `ipacc arguments`
