49 .Op Fl t Ar terminaltype
50 .Op Fl u Ar charging unit length
56 is the isdn4bsd package daemon which manages all ISDN related connection
57 and disconnection of ISDN devices supported by the package.
59 The options are as follows:
64 as the name of the runtime configuration filename for
66 instead of the default file
67 .Li /etc/isdn/isdnd.rc .
69 If debugging support is compiled into
71 this option is used to specify the debugging level, or better which kind
72 of debugging messages are displayed.
73 The debugging level is the sum of the
76 .Bl -tag -width Ds -compact -offset indent
92 isdn4bsd kernel i/o calls.
94 controller and channel busy/free messages.
96 isdnd.rc configuration file processing.
98 outgoing call budget handling.
100 valid keyword and holiday file processing.
103 The value can be specified in any number base supported by the
107 In addition, this option accepts also the character 'n' as an argument to
108 disable displaying debug messages on the full-screen display.
111 Specifying this option causes
113 to enter the full-screen mode of operation.
114 When operating in this mode,
115 entering the control character
117 causes the display to be refreshed and entering
121 will pop-up a command window.
124 utility will not listen to messages while the command window is active,
125 this command window will disappear automatically after 5 seconds without
126 any command key press.
128 While the command window is active,
132 advances to the next menu item.
133 To execute a command, press
137 for the highlighted menu item, or enter the number corresponding to the
138 item to be executed or enter the capitalized character in the menu item
141 If this option is set, logging is not done via the
143 facility but instead is appended to a file.
145 Specifies the name of the logfile which is used when the option
150 in the system section of
153 This option prints out the parsed and verified isdnd configuration in the same
154 format as the isdnd.rc file.
155 This output can be used as an isdnd.rc file.
157 feature is especially useful when debugging an isdnd.rc file to see, what the
158 default settings of options are when they are not set in the isdnd.rc input
163 exits after the printout is done.
167 to detach from the controlling tty and become a daemon.
169 In conjunction with the
173 specifies a terminal device which becomes the controlling tty for
175 and on which the full-screen mode output is displayed.
177 This option may be used to specify the logging facility in case
179 logging is configured and another facility than the default LOCAL0
180 facility shall be used.
181 The facility is to be specified as an integer in
182 the range 0-11 or 16-23 (see the file /usr/include/syslog.h).
184 In conjunction with the
190 specifies a terminal type or termcap entry name (such as vt220) for the device
194 This is useful if an unused (no getty running) tty line is
195 used for full-screen output for which no
197 environment variable exists.
199 Specifies the length of a charging unit in case the config file entry
205 If the isdn daemon is compiled with local or remote monitoring support,
206 this option disables all monitoring access.
207 It overrides the config
209 .Em monitor-allowed .
211 .Sh INTERACTION WITH THE KERNEL
215 communicates with the kernel part of isdn4bsd by receiving status and
220 and by transmitting commands and responses
225 The messages and message parameters are documented in the include
227 .Em /usr/include/machine/i4b_ioctl.h .
229 Supported command and response messages (ioctls) to the kernel are:
230 .Bl -tag -width Ds -compact -offset indent
232 Request a unique Call Description IDentifier (cdid) which identifies
233 uniquely a single interaction of the local D channel with the exchange.
234 .It Ar I4B_CONNECT_REQ
235 Actively request a call setup to a remote ISDN subscriber.
236 .It Ar I4B_CONNECT_RESP
237 Respond to an incoming call, either accept, reject or ignore it.
238 .It Ar I4B_DISCONNECT_REQ
239 Actively terminate a connection.
240 .It Ar I4B_CTRL_INFO_REQ
241 Request information about an installed ISDN controller card.
242 .It Ar I4B_DIALOUT_RESP
243 Give information about call setup to driver who requested dialing out.
244 .It Ar I4B_TIMEOUT_UPD
245 Update the kernels timeout value(s) in case of dynamically calculated
246 shorthold mode timing changes.
247 .It Ar I4B_UPDOWN_IND
248 Inform the kernel userland drivers about interface soft up/down status
250 .It Ar I4B_CTRL_DOWNLOAD
251 Download firmware to active card(s).
252 .It Ar I4B_ACTIVE_DIAGNOSTIC
253 Return diagnostic information from active cards.
257 Supported status and event messages from the kernel are:
258 .Bl -tag -width Ds -compact -offset indent
259 .It Ar MSG_CONNECT_IND
260 An incoming call from a remote ISDN user is indicated.
261 .It Ar MSG_CONNECT_ACTIVE_IND
262 After an incoming call has been accepted locally or an outgoing call has
263 been accepted by a remote, the exchange signaled an active connection
264 and the corresponding B-channel is switched through.
265 .It Ar MSG_DISCONNECT_IND
266 A call was terminated.
267 .It Ar MSG_DIALOUT_IND
268 A userland interface driver requests the daemon to dial out (typically a
269 network interface when a packet arrives in its send queue).
270 .It Ar MSG_IDLE_TIMEOUT_IND
271 A call was terminated by the isdn4bsd kernel driver because a B-channel
272 idle timeout occurred.
274 Accounting information from a network driver.
275 .It Ar MSG_CHARGING_IND
276 Charging information from the kernel.
280 Currently the only possibility to trigger an outgoing call is that an
281 isdn4bsd network driver
289 The daemon requests a new CDID from the kernel by using the
291 ioctl message, this CDID is now used in all interactions with the kernel
292 to identify this single call until a disconnect occurs.
294 After getting the CDID, the daemon looks up several additional information
295 in its entry section of the configuration corresponding to that connection
298 ioctl message to the kernel.
299 The kernel now dials the remote side and
300 if the remote side accepts the call, the kernel sends a
301 .Em MSG_CONNECT_ACTIVE_IND
304 The call is terminated by either the local side timing out or the remote
305 side hanging up the connection or the local side actively sending a
306 .Em I4B_DISCONNECT_REQ
307 ioctl message, both events are signaled to the
309 by the kernel sending the
310 .Em I4B_DISCONNECT_IND
311 message and the CDID corresponding to the call is no longer valid.
314 Incoming calls are signaled to the
316 by the kernel transmitting the
318 message to the daemon.
320 With the information contained in this message, the
322 searches the entry section of its configuration database and if a match is
323 found, it accepts or rejects the call or, if no match is found, it ignores the
324 call - all by issuing a
326 ioctl message with the appropriate parameters to the kernel.
328 In case the daemon decided to accept the call, the kernel signals this
330 .Em MSG_CONNECT_ACTIVE_IND
331 message to the daemon.
333 The call is terminated by either the local side timing out or the remote
334 side hanging up the connection or the local side actively sending a
335 .Em I4B_DISCONNECT_REQ
336 ioctl message, both events are signaled to the
338 by the kernel sending the
339 .Em I4B_DISCONNECT_IND
340 message and the CDID corresponding to the call is no longer valid.
342 Sending a HUP signal to
344 causes all open connections to be terminated and the configuration file is
346 In case aliasfile handling was enabled, the aliasfile is also
349 Sending a USR1 signal to
351 causes the accounting file and the logfile (if logging to a file is used
352 instead of logging via the
354 facility) to be closed and reopened to make logfile rotation possible.
356 The following environment variables affect the execution of
360 The terminal type when running in full-screen display mode.
363 for more information.
366 .Bl -tag -width /etc/isdn/isdnd.rates
368 The device-file used to communicate with the kernel ISDN driver subsystem.
369 .It Pa /var/log/messages
370 A record of the actions in case of syslogd logging support.
371 .It Pa /var/log/isdnd.acct
372 The default accounting information filename (if accounting is configured).
373 .It Pa /var/log/isdnd.log
374 The default logging filename (if logging to a file is configured).
375 .It Pa /var/run/isdnd.pid
376 The process id of the isdn daemon (also known as "lockfile" to isdnd, preventing multiple invocations of it).
377 .It Pa /usr/local/lib/isdn
379 The directory where isdnd expects some supplementary data files and programs
380 for telephone answering support.
381 .It Pa /etc/isdn/isdnd.rc
382 The default runtime configuration file.
383 .It Pa /etc/isdn/isdnd.rates
384 The default unit charging rates specification file.
385 .It Pa /etc/isdn/isdntel.alias
386 The default table (if aliasing is enabled) to convert phone number to caller's name.
389 For a first try, the following command should be used to start
391 in foreground mode for better debugging the configuration setup:
392 .Bd -literal -offset indent
396 This will start isdnd with reasonable debugging settings and produce
397 output on the current terminal.
400 utility can then be terminated by entering Control-C.
402 Another example, the command:
403 .Bd -literal -offset indent
404 isdnd -d0xf9 -f -r /dev/ttyv3 -t vt100
409 with reasonable debugging messages enabled, full-screen mode of operation,
410 full-screen display redirected to /dev/ttyv3 and using a termcap entry
411 for vt100 on this display.
413 Exit status is 0 on success, 1 on error.
