.Sh DESCRIPTION
|
|
.Nm Isdnd
|
|
is the isdn4bsd package demon which manages all ISDN related connection
|
|
and disconnection of ISDN devices supported by the package.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Fl c
|
|
Use
|
|
.Ar configfile
|
|
as the name of the runtime configuration filename for
|
|
.Nm isdnd
|
|
instead of the default file
|
|
.Li /etc/isdn/isdnd.rc .
|
|
.It Fl d
|
|
If debugging support is compiled into
|
|
.Nm isdnd
|
|
this option is used to specify the debugging level, or better which kind
|
|
of debugging messages are displayed. The debugging level is the sum of the
|
|
following values:
|
|
.Pp
|
|
.Bl -tag -width Ds -compact -offset indent
|
|
.It Ar 0x001
|
|
general debugging.
|
|
.It Ar 0x002
|
|
rates calculation.
|
|
.It Ar 0x004
|
|
timing calculations.
|
|
.It Ar 0x008
|
|
state transitions.
|
|
.It Ar 0x010
|
|
retry handling.
|
|
.It Ar 0x020
|
|
dialing.
|
|
.It Ar 0x040
|
|
process handling.
|
|
.It Ar 0x080
|
|
isdn4bsd kernel i/o calls.
|
|
.It Ar 0x100
|
|
controller and channel busy/free messages.
|
|
.It Ar 0x200
|
|
isdnd.rc configuration file processing.
|
|
.El
|
|
.Pp
|
|
The value can be specified in any number base supported by the
|
|
.Xr sscanf 3
|
|
library routine.
|
|
.Pp
|
|
In addition, this option accepts also the character 'n' as an argument to
|
|
disable displaying debug messages on the full-screen display.
|
|
.Pp
|
|
.It Fl f
|
|
Specifying this option causes
|
|
.Nm isdnd
|
|
to enter the full-screen mode of operation. When operating in this mode,
|
|
entering the control character
|
|
.Em Control-L
|
|
causes the display to be refreshed and entering
|
|
.Em Carriage-Return
|
|
or
|
|
.Em Enter
|
|
will pop-up a command window. Because the
|
|
.Nm
|
|
daemon will not listen to messages while the command window is active,
|
|
this command window will disappear automatically after 5 seconds without
|
|
any command key press.
|
|
.Pp
|
|
While the command window is active,
|
|
.Em Tab
|
|
or
|
|
.Em Space
|
|
advances to the next menu item. To execute a command, press
|
|
.Em Return
|
|
or
|
|
.Em Enter
|
|
for the highlighted menu item, or enter the number corresponding to the
|
|
item to be executed or enter the capitalized character in the menu item
|
|
description.
|
|
.It Fl l
|
|
If this option is set, logging is not done via the
|
|
.Xr syslogd 8
|
|
facility but instead is appended to a file.
|
|
.It Fl L
|
|
Specifies the name of the logfile which is used when the option
|
|
.Em -l
|
|
is set. See also the keyword
|
|
.Em rotatesuffix
|
|
in the system section of
|
|
.Xr isdnd.rc 5 .
|
|
.It Fl P
|
|
This option prints out the parsed and verified isdnd configuration in the same
|
|
format as the isdnd.rc file. This output can be used as an isdnd.rc file. This
|
|
feature is especially useful when debugging an isdnd.rc file to see, what the
|
|
default settings of options are when they are not set in the isdnd.rc input
|
|
file.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
exits after the printout is done.
|
|
.It Fl F
|
|
This option prevents
|
|
.Nm isdnd
|
|
to detach from the controlling tty and become a daemon.
|
|
.It Fl r
|
|
In conjunction with the
|
|
.Fl t
|
|
option,
|
|
.Ar device
|
|
specifies a terminal device which becomes the controlling tty for
|
|
.Nm isdnd
|
|
and on which the full-screen mode output is displayed.
|
|
.It Fl s
|
|
This option may be used to specify the logging facility in case
|
|
.Xr syslog 3
|
|
logging is configured and another facility than the default LOCAL0
|
|
facility shall be used. The facility is to be specified as an integer in
|
|
the range 0-11 or 16-23 (see the file /usr/include/syslog.h).
|
|
.It Fl t
|
|
In conjunction with the
|
|
.Fl f
|
|
and
|
|
.Fl r
|
|
options,
|
|
.Ar terminaltype
|
|
specifies a terminal type or termcap entry name (such as vt220) for the device
|
|
used for
|
|
.Nm isdnd
|
|
full-screen output. This is useful if an unused (no getty running) tty line is
|
|
used for full-screen output for which no
|
|
.Li TERM
|
|
environment variable exists.
|
|
.It Fl u
|
|
Specifies the length of a charging unit in case the config file entry
|
|
keyword
|
|
.Em unitlenghtsrc
|
|
is set to
|
|
.Em cmdl .
|
|
.It Fl m
|
|
If the isdn daemon is compiled with local or remote monitoring support,
|
|
this option disables all monitoring access. It overrides the config
|
|
file option
|
|
.Em monitor-allowed .
|
|
.El
|
|
.Pp
|
|
.Sh INTERACTION WITH THE KERNEL
|
|
.Nm Isdnd
|
|
communicates with the kernel part of isdn4bsd by receiving status and
|
|
event messages (
|
|
.Xr read 2
|
|
from device /dev/i4b ) and by transmitting commands and responses (
|
|
.Xr ioctl 2
|
|
from device /dev/i4b ).
|
|
.Pp
|
|
The messages and message parameters are documented in the include
|
|
file
|
|
.Em /usr/include/machine/i4b_ioctl.h .
|
|
.Pp
|
|
Supported command and response messages (ioctl's) to the kernel are:
|
|
.Bl -tag -width Ds -compact -offset indent
|
|
.It Ar I4B_CDID_REQ
|
|
Request a unique Call Description IDentifier (cdid) which identifies
|
|
uniquely a single interaction of the local D channel with the exchange.
|
|
.It Ar I4B_CONNECT_REQ
|
|
Actively request a call setup to a remote ISDN subscriber.
|
|
.It Ar I4B_CONNECT_RESP
|
|
Respond to an incoming call, either accept, reject or ignore it.
|
|
.It Ar I4B_DISCONNECT_REQ
|
|
Actively terminate a connection.
|
|
.It Ar I4B_CTRL_INFO_REQ
|
|
Request information about an installed ISDN controller card.
|
|
.It Ar I4B_DIALOUT_RESP
|
|
Give information about call setup to driver who requested dialing out.
|
|
.It Ar I4B_TIMEOUT_UPD
|
|
Update the kernels timeout value(s) in case of dynamically calculated
|
|
shorthold mode timing changes.
|
|
.It Ar I4B_UPDOWN_IND
|
|
Inform the kernel userland drivers about interface soft up/down status
|
|
changes.
|
|
.It Ar I4B_CTRL_DOWNLOAD
|
|
Download firmware to active card(s).
|
|
.It Ar I4B_ACTIVE_DIAGNOSTIC
|
|
Return diagnostic information from active cards.
|
|
.El
|
|
.Pp
|
|
.Pp
|
|
Supported status and event messages from the kernel are:
|
|
.Bl -tag -width Ds -compact -offset indent
|
|
.It Ar MSG_CONNECT_IND
|
|
An incoming call from a remote ISDN user is indicated.
|
|
.It Ar MSG_CONNECT_ACTIVE_IND
|
|
After an incoming call has been accepted locally or an outgoing call has
|
|
been accepted by a remote, the exchange signaled an active connection
|
|
and the corresponding B-channel is switched through.
|
|
.It Ar MSG_DISCONNECT_IND
|
|
A call was terminated.
|
|
.It Ar MSG_DIALOUT_IND
|
|
A userland interface driver requests the daemon to dial out (typically a
|
|
network interface when a packet arrives in its send queue).
|
|
.It Ar MSG_IDLE_TIMEOUT_IND
|
|
A call was terminated by the isdn4bsd kernel driver because a B-channel
|
|
idle timeout occurred.
|
|
.It Ar MSG_ACCT_IND
|
|
Accounting information from a network driver.
|
|
.It Ar MSG_CHARGING_IND
|
|
Charging information from the kernel.
|
|
.El
|
|
.Pp
|
|
.Ss OUTGOING CALLS
|
|
Currently the only possibility to trigger an outgoing call is that an
|
|
isdn4bsd network driver
|
|
.Em (ipr<n>)
|
|
sends a
|
|
.Em MSG_DIALOUT_IND
|
|
to the
|
|
.Nm
|
|
daemon.
|
|
.Pp
|
|
The daemon requests a new CDID from the kernel by using the
|
|
.Em I4B_CDID_REQ
|
|
ioctl message, this CDID is now used in all interactions with the kernel
|
|
to identify this single call until a disconnect occurs.
|
|
.Pp
|
|
After getting the CDID, the daemon looks up several additional information
|
|
in its entry section of the configuration corresponding to that connection
|
|
and issues a
|
|
.Em I4B_CONNECT_REQ
|
|
ioctl message to the kernel. The kernel now dials the remote side and
|
|
if the remote side accepts the call, the kernel sends a
|
|
.Em MSG_CONNECT_ACTIVE_IND
|
|
to the daemon.
|
|
.Pp
|
|
The call is terminated by either the local site timing out or the remote
|
|
side hanging up the connection or the local side actively sending a
|
|
.Em I4B_DISCONNECT_REQ
|
|
ioctl message, both events are signaled to the
|
|
.Nm
|
|
by the kernel sending the
|
|
.Em I4B_DISCONNECT_IND
|
|
message and the CDID corresponding to the call is no longer valid.
|
|
.Pp
|
|
.Ss INCOMING CALLS
|
|
Incoming calls are signaled to the
|
|
.Nm
|
|
by the kernel transmitting the
|
|
.Em MSG_CONNECT_IND
|
|
message to the daemon.
|
|
.Pp
|
|
With the information contained in this message, the
|
|
.Nm
|
|
searches the entry section of its configuration database and if a match is
|
|
found, it accepts or rejects the call or, if no match is found, it ignores the
|
|
call - all by issuing a
|
|
.Em I4B_CONNECT_RESP
|
|
ioctl message with the appropriate parameters to the kernel.
|
|
.Pp
|
|
In case the daemon decided to accept the call, the kernel signals this
|
|
by sending a
|
|
.Em MSG_CONNECT_ACTIVE_IND
|
|
message to the daemon.
|
|
.Pp
|
|
The call is terminated by either the local site timing out or the remote
|
|
side hanging up the connection or the local side actively sending a
|
|
.Em I4B_DISCONNECT_REQ
|
|
ioctl message, both events are signaled to the
|
|
.Nm
|
|
by the kernel sending the
|
|
.Em I4B_DISCONNECT_IND
|
|
message and the CDID corresponding to the call is no longer valid.
|
|
.Pp
|
|
|
|
.Sh SIGNALS
|
|
|
|
Sending a HUP signal to
|
|
.Nm
|
|
causes all open connections to be terminated and the configuration file is
|
|
reread. In case aliasfile handling was enabled, the aliasfile is also
|
|
reread.
|
|
|
|
Sending a USR1 signal to
|
|
.Nm
|
|
causes the accounting file and the logfile (if logging to a file is used
|
|
instead of logging via the
|
|
.Xr syslog 3
|
|
facility) to be closed and reopened to make logfile rotation possible.
|
|
|
|
.Sh ENVIRONMENT
|
|
The following environment variables affect the execution of
|
|
.Nm isdnd :
|
|
.Bl -tag -width Ds

.Sh EXAMPLES
|
|
For a first try, the following command should be used to start
|
|
.Nm
|
|
in foreground mode for better debugging the configuration setup:
|
|
.Bd -literal -offset indent
|
|
isdnd -d0xf9 -F
|
|
.Ed
|
|
.Pp
|
|
This will start isdnd with reasonable debugging settings and produce
|
|
output on the current terminal.
|
|
.Nm Isdnd
|
|
can then be terminated by entering Control-C.
|
|
.Pp
|
|
Another example, the command:
|
|
.Bd -literal -offset indent
|
|
isdnd -d0xf9 -f -r /dev/ttyv3 -t vt100
|
|
.Ed
|
|
.Pp
|
|
will start
|
|
.Nm isdnd
|
|
with reasonable debugging messages enabled, full-screen mode of operation,
|
|
full-screen display redirected to /dev/ttyv03 and using a termcap entry
|
|
for vt100 on this display.
|
|
.Sh DIAGNOSTICS
|
|
Exit status is 0 on success, 1 on error.
