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

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.
