ibod - ISDN MPPP bandwidth on demand daemon
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
Ibod also supports more than one additional channel - see ibod.cf(4)
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
Upon receiving SIGHUP, the configuration file is re-read. A SIGPIPE
closes an eventual socket connection with xibod.
Variable IBOD_HOME specifies the directory where to look for the
configuration file ibod.cf.
All logging is made to syslog with the identity tag ibod.
