NAME

       ipfm.conf - IP Flow Meter configuration file

DESCRIPTION

       ipfm.conf is ipfm(8) configuration file.

       A  hash  mark  (``#'')  indicates  that  the  end  of the line is a comment and it will be
       ignored.

       The configuration rules will be interpreted from the end, and the first matching rule will
       be used, unless specified here.

       IPFM  uses  local  and  global  variables,  so it can manage multiple logs (different time
       delay, different hosts, different log filename ...) at the same time.

       Global variables will be used for all logs and local variables will only be  used  in  the
       log being defined.

GLOBAL VARIABLES

   NETWORK DEVICE
       Syntax : DEVICE <device-name>

       <device-name>
              is the device on witch ipfm will log packets. IPFM monitors only one device.

   Time Coordinates
       Syntax : [UTC|local]

       This  decides  if  IPFM  will  use  UTC or local time in its outputs (log filename and the
       timestamp inside the file). Default is local.

       Note that IPFM works internally with UTC, and that the dates entered in  the  config  file
       are UTC (see AFTER Syntax).

   NEW LOG
       Syntax : NEWLOG

       This creates a new log entry, where you can define new local variables.

LOCAL VARIABLES

   HOSTS TO LOG
       ipfm logs only specified hosts.

       Syntax: LOG [[NONE|FROM|TO|BOTH] <host>] [[NOT] WITH <host>]

       NONE   do not log anything from or to this <host>

       FROM   do log packets from this <host>

       TO     do log packets to this <host>

       BOTH   (default) do log packets from and to this <host>

       <host> can be :
              x.x.x.x           : an IP.  x.x.x.x/x.x.x.x : an IP followed by a subnet mask.

       WITH   specifies  if the packet is ignored (NOT WITH) or logged (WITH), in function of the
              second IP present in the packet.

       Examples :
              LOG 10.10.10.0/255.255.255.0 NOT WITH 10.10.10.1
               will log any packets from or to hosts in subnet  10.10.10.0/255.255.255.0,  except
              packets involving host 10.10.10.1 .

              LOG WITH 10.10.10.23
               will log any packets in relation with host 10.10.10.23

              LOG
               will log everything.

   OUTPUT TIME DELAY
       ipfm  outputs  its  statistics  every  fixed period, with the ability to fix an exact time
       origin and offset, in Coordinated Universal Time (UTC).

       Syntax: DUMP EVERY <time> [AFTER <time>]

       <time> is composed of :
               <number> second(s)
               <number> minute(s)
               <number> hour(s)
               <number> day(s)

              Default DUMP time is 24 hours

              Default AFTER time is 0 seconds

       Examples:
              DUMP EVERY 30 minutes
               will dump the stats every 30 minutes at x:00 and x:30.

              DUMP EVERY 1 hour AFTER 7 minutes
               will dump the stats every hour, at 0:07, 1:07, 2:07, and so on, regardless of  the
              time at which ipfm was launched.

              DUMP EVERY 1 day AFTER 14 hours
               will  dump  data  every  day,  at  14:00:00  UTC (for France localtime (during the
              summer), at 16:00:00 +0200)

   CLEARING STATS
       You may want to clear your statistics sometimes, or after each dump.

       Syntax : CLEAR [ ALWAYS | NEVER | EVERY <time> [AFTER <time>] ]

       <time> is composed of :
               <number> second(s)
               <number> minute(s)
               <number> hour(s)
               <number> day(s)

              Default CLEAR mode is ALWAYS. Default AFTER time is 0 seconds. Note that both  time
              values  MUST  be  a multiple of the DUMP delay. Also, this line MUST come after the
              DUMP line.

       Examples
              CLEAR ALWAYS
               will clear the stats after every DUMP.

              CLEAR NEVER
               will never clear the stats, which means you are doing incremental statistics.

              CLEAR EVERY 30 minutes
               will clear the stats every 30 minutes at x:00 and x:30. Note  that  if  your  DUMP
              line  had  an AFTER value such as 3 minutes, this rule will clear the stats at x:03
              and x:33.

              CLEAR EVERY 1 hour AFTER 10 minutes
               will clear the stats every hour, at 0:10, 1:10, 2:10, and so on. Note that if your
              DUMP  line  had an AFTER value such as 3 minutes, this rule will clear the stats at
              0:13, 1:13, 2:13 and so on.

   LOG FILENAME
       Every delay, ipfm writes its output into a file, which  name  is  specified  by  the  rule
       FILENAME

       Syntax: FILENAME <filemask>

       <filemask>
              is  a  quoted  string  (eg.  "/path/to/filename")  that is parsed using strftime(3)
              syntax.

       Default FILENAME is /var/log/ipfm/%d-%b.%H-%M
              NOTE : The file will be overwritten without any check.

   REVERSE DNS
       You can activate or deactivate reverse DNS in the output file.

       WARNING : activating reverse DNS can delay a lot the production of the log  file,  due  to
       DNS timeouts.

       Syntax : [RESOLVE|NORESOLVE]

       Default is NORESOLVE

   SORT OUTPUT FILE
       ipfm can sort output file depending on IN, OUT or TOTAL.

       Syntax : SORT IN|OUT|TOTAL

       Default is to sort nothing. Please note that this option could delay a bit
              the production of the log file.

   SET PROMISCUOUS MODE
       You  can  choose  to  log  all  packets  on  the  network  (default) or only packets which
       destination is your network device.

       This option could also be useful  if  you  wish  to  set  the  promiscuous  mode  yourself
       (ifconfig eth0 [-]promisc), as the promisc mode is very badly handled under Linux.

       Please  note  that  under  Linux, if you run a program that sets the promiscuous mode (for
       example tcpdump), ipfm will also see its network interface set into promiscuous mode.

       Syntax [NO]PROMISC

       Default is PROMISC

   APPEND OR REPLACE LOG FILES
       You can choose to append the output to an existing logfile or to replace the old file by a
       new one.

       Syntax : APPEND|REPLACE

       Default is REPLACE
