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.
