NAME

       ibod - ISDN MPPP bandwidth on demand daemon

SYNOPSIS

       ibod

DESCRIPTION

       Ibod  is  a  ISDN MPPP bandwidth on demand daemon designed to operate in conjunction with isdn4linux.  It is normally started at boot time,
       but can be started and stopped at any time. The program monitors inbound and outbound traffic on the  ISDN  interface.  When  the  required
       bandwidth  exceeds  the capacity for one ISDN B-channel (64kbps) a second (slave) channel is connected according to the MPPP protocol. When
       the traffic decreases below one channel capacity, the slave channel is disconnected.

       Ibod also supports more than one additional channel - see ibod.cf(4) for details.

       A configuration file /etc/isdn/ibod.cf is read initially.  The device /dev/isdninfo is monitored for the current state  and  throughput	of
       the ISDN interface.  All operation on the ISDN interface is made through the /dev/isdnctrl interface.

       Ibod is also listening on TCP port 6050 for eventual connection from control panel xibod(1).

SIGNALS

       Upon receiving SIGHUP, the configuration file is re-read.  A SIGPIPE closes an eventual socket connection with xibod.

ENVIRONMENT

       Variable IBOD_HOME specifies the directory where to look for the configuration file ibod.cf.

DIAGNOSTICS

       All logging is made to syslog with the identity tag ibod.

NAME

       ibod.cf - configuration file for ibod (ISDN Bandwidth On Demand)

DESCRIPTION

       This file contains the initial configuration values for the ibod daemon. Each line contains a keyword and a value.

       Boolean attributes are set with 0 or 1 which corresponds to false and true respectively. A boolean attribute not specified at all is always
       false.

       Lines beginning with # are treated as comments and will be ignored.

       IMPORTANT RULES!
       1. Keywords are case sensitive.
       2. Kewords must begin at the first column.
       3. Keywords and values must be separated by exactly one (1) space or tab character.

       This file is re-read every time ibod receives SIGHUP (1) signal.

   OPTIONS
       DEVICE <name>
	      Name of ISDN PPP device. Default is ippp0.

       ENABLE 1|0
	      Enable/disable bandwidth-on-demand.  Default is enable (1).

       INTERVAL <n>
	      Specify the sample time interval in ms.  Default is 500 ms.

       FILTER <n>
	      Defines "filtering factor". A value of 10 means that the average bytes/sec value measured over 10  intervals  must  pass	the  limit
	      defined by LIMIT to bring up or down the slave link.  Default is 5.

       LIMIT <n>
	      Transfer rate limit in bytes/sec for bringing up or down ISDN slave channel. Default is 7000.

       STAYUP 0|1
	      Enable/disable  slave channel stay up function.  If enabled, the 2:nd cannel (slave link) will stay up even if the average bytes/sec
	      decrease the value defined by LIMIT. In this case the slave link will stay up until hangup time is reached.  (Example: isdnctrl hup-
	      timeout ippp1 60) If disabled the slave link will be brought down in the same way it was brought up.  Default is 0.

       STAYUP_TIME <n>
	      Defines the minimum time in seconds the 2:nd channel will unconditionally stay up after it has been brought up. Default value is 30.
