NAME

6       isdnlog - isdn log system (and more)
7

DESCRIPTION

9       Isdnlog gets information from your isdn card, decodes this information,
10       and can do anything with it, such as logging,  starting  programs,  and
11       more. All options to isdnlog can be given as command line flags, or you
12       can specify a file with options (recommended).
13

RESTRICTION

15       Isdnlog only works with the HiSax isdn driver. Other cards  with  their
16       own driver are not supported. Additionally you need to enable d-channel
17       logging (you can use "hisaxctrl  <DriverId>  1  4"  to  do  that,  e.g.
18       "hisaxctrl line0 1 4"). Isdnlog can only log outgoing calls that origi‐
19       nate from your isdn card, and incoming calls. To get information  about
20       outgoing  calls  from  other isdn devices (e.g. telephones), you need a
21       second Teles isdn card, with crossed lines. Such a card is  not  usable
22       for communicating, but can log outgoing calls from any device (see dual
23       option below).
24

GENERAL OPTIONS

26       -V     show version information and exit.
27
28       -fFILE read options from the config  file  FILE.   This  file  is  also
29              called  the parameter file of isdnlog.  The first line should be
30              "[options]". You may use blank lines and comments (starting with
31              a #).  All config files for isdnlog have the format described in
32              isdn.conf(5).  Debug options must be given on the command  line,
33              they cannot be stored in a file.
34
35       /dev/DEVICE
36              isdnlog  will  read from this device and from /dev/isdninfo. You
37              should give /dev/isdnctrl0 for the first isdn card (or /dev/isd‐
38              nctrl2 for the second).
39
40              Isdnlog  has a replay mode for debugging, where you can simulate
41              previous recorded events. In that case  use  "-"  instead  of  a
42              device.
43
44       -Ax  amt="value"
45              Set  digits  necessary  to  get  an outside line, when connected
46              through a PABX.  You can give several codes padded  with  a  ":"
47              (e.g. -A0:80:81:82).
48
49       areacode="value"
50              (There  is no commandline option for this.)  Overwrite area code
51              from isdn.conf.  A machine connected to  subscriber  lines  with
52              different  area codes and thus several isdnlogs running requires
53              this non global setting.
54
55       -Bvbn     vbn="value"
56              Set the provider preselection to the given value. More  prefixes
57              may be separated by a ":".
58              Values  are  e.g. "010" for DE, "10" for AT, "16:17" for NL, "9"
59              for FR.
60
61       -Rprefix  preselected="value"
62              Set the preselected provider (i.e the  chosen  provider,  if  no
63              prefix is dialed) to value. Value should be without vbn.
64
65       skipProv=skiplist
66              (There  is  no  commandline  option  for  this.)  Ignore certain
67              providers from the rate-file.  The format  of  skiplist  is  the
68              same as for Q: tags in rate.conf and described in rate.conf(5).
69
70       -0x:y     trim="value[:value]"
71              Suppress leading digits. If isdnlog is connected through a PABX,
72              it is sometimes not possible to let isdnlog distinguish  between
73              a  national  and an international call, even with help of the -A
74              option.
75              This option requires two values separated with ":" as  an  argu‐
76              ment.  These  values  tell  isdnlog  how  many leading digits to
77              remove from incoming and outgoing calls  respectively.  If  only
78              one  value  is  given, it is used for both incoming and outgoing
79              calls.
80              Don't use this in combination with the -A option! This will con‐
81              fuse the system (and possibly you).
82
83              Example:  a PABX in Germany shows the number of an incoming call
84              from Hamburg as "00040...".  When calling  out  to  Hamburg,  it
85              shows  the  number  as  "0040...".   This means that on incoming
86              calls, three zeroes must be removed, and on outgoing  calls  two
87              zeroes  must  be  removed  (the  number must be normalized to be
88              without any leading zeroes in the case  of  a  national  number;
89              international  numbers  must have one leading zero). So, in this
90              case, the option -03:2 would be correct.
91
92       -ix  internS0="value"
93              Telephone numbers shorter then value are considered to be inter‐
94              nal numbers on your PABX.
95
96       -o   other={yes|no}
97              Normally  "causes" (e.g. "non-selected user clearing") for other
98              connected ISDN devices are not displayed, only those  which  are
99              related  to  the  connection will be shown. With this option the
100              causes for the other devices are also displayed.
101
102       -ux  ignoreRR="value"
103              Ignore "housekeeping" frames.  x may be  1  (ignore  RR=Receiver
104              ready) or 2 (ignore EMP=Euracom Management Protokoll) frames.
105
106       -Ux[:y]   ignoreCOLP="value[:value]"
107              Ignore  COLP/CLIP frames when value is 1 or greater.  Value 0 is
108              default, and tells isdnlog to not ignore COLP/CLIP frames.  With
109              value 2 the ignored COLP/CLIP number is displayed.
110              The  first value applies to COLP the second to CLIP. If only one
111              value is given, it applies to COLP and CLIP.
112              Sometimes the COLP number is a number in a different areacode to
113              the number that was dialled, and then the cost calculation would
114              be wrong.
115
116       ignoreUPD={yes|no}
117              (There is no commandline option for this.)   A  PABX  may  cause
118              numerous   messages   like  "Unexpected  discriminator  0x47  --
119              ignored!" resulting from protocol discriminator values in  layer
120              3  not  known to isdnlog.  Set ignoreUPD to yes to suppress this
121              messages.
122
123       -2x  dual="value"
124              Enable dual mode. You need this if you have a second  isdn  card
125              attached  with crossed lines so it can listen to what other isdn
126              devices like telephones are doing. With x=2 you can increase the
127              debug output - every single digit will be displayed.
128
129              Some setups may require workarounds for reliable logging.  These
130              workarounds are enabled by addition of the following numbers  to
131              the dual value.  They are intended for the dualmode but may also
132              be useful without.  In this case, specify only the  sum  of  the
133              following numbers without 1 or 2 for the dual mode.
134
135              0x100  Enable  this  when  the destination number of an outgoing
136                     call contains the number of the previous call, e.g. call‐
137                     ing  222  after  calling 111 before results in 111222 for
138                     the second call.
139
140                     This may also help  in  situations  where  an  unanswered
141                     incoming  call  causes incorrect logging of the following
142                     outgoing call.
143
144              0x200  Enable this when outgoing  calls  are  logged  without  a
145                     source number (own MSN).
146
147              0x400  Enable  this  when  unanswered  incoming calls are logged
148                     multiple times (revealed by isdnrep -E).
149
150       -1     A HFC-based card is used for echo mode. Enable echo mode for the
151              HFC card with
152              hisaxctrl id 10 1
153              hisaxctrl id 12 1
154

DEBUG MODULE

156       -r     Replay  a  debug  file  (e.g. /tmp/isdnctrl0) to find bugs. With
157              this flag you should give a filename with the debug  information
158              instead  of  a device.  It will also work with files not created
159              by isdnlog (e.g.  "cat /dev/isdnctrl0").
160
161       -n   newline={yes|no}
162              Display throughput messages on the same line (only  useful  with
163              logging to stderr or a console device).
164
165       -WX  width="value"
166              Limit all messages to X characters per line.
167
168       -vX  log=X
169              Isdnlog  can copy all information to /tmp/DEVICE (e.g. /tmp/isd‐
170              nctrl0 if you started isdnlog with /dev/isdnctrl0). Choose  what
171              debugging  you want from the following list, add the correspond‐
172              ing numbers together and use that for X:
173
174              1      copy all "HEX:" lines from the hisax isdn device driver.
175              2      copy /dev/isdnctrl output (or whatever device you  speci‐
176                     fied).
177              4      copy /dev/isdninfo output
178              8      copy transfer values ("ibyte","obyte").
179
180              Isdnlog will close and reopen this file after a "kill -HUP".
181
182       -s   flush={yes|no}
183              Isdnlog  will flush the debug file /tmp/DEVICE (e.g. /tmp/isdnc‐
184              trl0) after each write access.
185
186       -P   pipe={yes|no}
187              Copy the debug information to  stdout.  This  way  you  can  run
188              isdnlog  as the source of a pipe like "isdnlog -P /dev/isdnctrl0
189              |prog ... ".
190
191       -D   daemon={yes|no}
192              Start isdnlog as daemon: it will fork into the  background,  and
193              use syslog as the default logging method (if you did not specify
194              -m).
195
196       -T     Trace mode: isdnlog will wait for a key after processing a  line
197              from /dev/isdnctrl0 (or whatever device you specified).
198
199       -K     Print  for  every pressed key the thruput. Can not used together
200              with option -d.
201
202       -b     If you are using a bilingual network terminator (NT),  you  must
203              give this flag, or isdnlog will show the own MSN's incorrectly.
204

NUMBER REWRITE MODULE

206       You  can define aliases for telephone numbers (see callerid.conf(5) and
207       isdn.conf(5) for more information). Isdnlog will compare all numbers to
208       the  list of aliases, and when a match is found, the alias is displayed
209       instead of the number.
210

LOG MODULE

212       Isdnlog can log information via syslog, to stdout, and send information
213       to x11 clients. Calculate a code from these numbers by adding them, and
214       activate logging with -s, -m or -x. You can use normal numbers  or  hex
215       numbers. Default is stderr mode -m, unless daemon mode is enabled; then
216       it's syslog mode -l.
217
218       0x1    Errors
219
220       0x2    Warnings
221
222       0x4    Notice
223
224       0x8    Log messages to /tmp/DEVICE (e.g. /tmp/isdnctrl0 if  isdnlog  is
225              started with /dev/isdnctrl0)
226
227       0x10   Show telephone numbers immediately.
228
229       0x20   Show charge int and telephone costs with every charge signal (in
230              Germany, and perhaps other countries, you have  to  pay  to  get
231              these signals).
232
233       0x40   Show connect messages.
234
235       0x80   Show hang up messages.
236
237       0x100  Show cause message on hang up.
238
239       0x200  Show time messages.
240
241       0x400  Show throughput in bytes (every -wX seconds).
242
243       0x800  Show state of B-channels (use with -M monitor).
244
245       0x1000 Show service indicator.
246              You should log at least 0x7 (errors, warnings, notice) messages.
247
248       0x2000 Log estimated time till next charge signal.
249
250       0x4000 Show chargemax.
251
252       0x8000 Enable core file on SIGSEGV.
253
254       0x10000 ... 0x800000, show more diagnostic and debug messages.
255
256       -mX  stdout="value"
257              Log to stderr.
258
259       -OX  outfile="path"
260              Log  to file X instead of stderr. Isdnlog will close this device
261              when it gets a signal -SIGHUP (-1). Only valid with -m option.
262              If the name starts with a "+", new data will be appended to  the
263              existing  file.   Default behaviour is to truncate the file when
264              isdnlog opens it.
265
266       -C X      console="path"
267              Log to console X instead of  stderr.  You  can  use  -O  and  -C
268              together,  so that isdnlog copies output to both. Specify a full
269              pathname.  Beware: you must put a space between -C and X !
270
271       -M   monitor={yes|no}
272              With this flag, isdnlog will generate output  for  monitor  pro‐
273              grams  like imon, imontty or isdnmon. You must also give -m with
274              0x800 enabled.
275
276       -lX  syslog="value"
277              Log to syslog. X is the log code. You can log to syslog  and  to
278              stdout at the same time.
279
280       -xX  xisdn="value"
281              Pass  information to x11 client. X is the log code. You can pass
282              information to x11 clients and log to syslog  and/or  stdout  at
283              the same time.
284
285       -pPORT port="value"
286              Pass information to x11 client on this PORT.
287
288       -cX  calls="value"
289              Only  with -xX : save the last X calls and pass this information
290              to an x11 client. Default value is 100.
291
292       -LX  xlog="value"
293              Only with -xX : save the last X messages and pass this  informa‐
294              tion to an x11 client. Default value is 500.
295
296       -wX  thruput="value"
297              If  you enabled throughput logging (0x400), isdnlog will log the
298              throughput every X seconds.
299
300       -Ix:y     ciinterval="value[:value]"
301              Interval for printing of charge messages (0x20).
302              The first value is the interval for the calculated CI, the  sec‐
303              ond  value  for  the  EH  (AOC-D) messages. If only one value is
304              given, both intervals are set to this value.
305

LCR

307       -dx  abclcr="value"
308              Value is a bitmap:
309              0 ... off
310              1 ... calls to different area / country
311              2 ... local calls too
312              4 ... special numbers e.g. ISP
313              This needs a kernel patch to work. If the kernel  patch  is  not
314              found a simulation is done.
315              Note:  depending on your telephone provider local area calls may
316              or may not be routed to alternate providers.  For  changing  the
317              ISP a script is called. s. next option 'providerchange'
318
319       providerchange="path_top_script"
320              (There  is  no  commandline  option  for  this.)  This script is
321              called with 3 parameters, the new provider  number  (from  rate-
322              CC.dat), the number, which would be dialed, and the servicename.
323              The script should adjust routing, name resolution and so  on  to
324              connect  to  the  ISP.  If the script returns non zero, LCR will
325              not be done.
326
327

TIME MODULE

329       -tX  time={0|1|2}
330              Isdnlog will set your local system time to the time  transmitted
331              by your isdn service provider: -t1 = once, -t2 = every time.
332

CHARGEHUP MODULE

334       -hX  hangup="value"
335              The  isdn  kernel system has a chargehup system, so it will hang
336              up a few seconds before the next charge signal. If you don't get
337              a charge signal from your phone company, isdnlog can emulate it.
338
339              On  every outgoing connection, isdnlog will calculate the charge
340              time from day of week, time of day and the distance zone of  the
341              connection.
342
343              The  kernel  needs  to know how long the charge time is, and how
344              many seconds before the next charge signal it  should  hang  up.
345              You  have  to  set  the second parameter with X in the form num‐
346              ber:number (hang up seconds before next charge signal for charge
347              times  greater than or equal to 20 seconds : for charge times of
348              less than 20 seconds).
349
350              With this information, isdnlog  will  call  "isdnctrl  chargeint
351              <device>  <charge time>" and "isdnctrl huptimeout <device> <sec‐
352              onds before charge signal>" (it actually  communicates  directly
353              with  isdn,  without  calling  isdnctrl, but this would have the
354              same effect).
355
356              You should run isdnlog with -t1 or better with -t2,  so  isdnlog
357              sets the local time in sync with telephone switching office.
358
359              If there is a third number in value, this is the minimum connec‐
360              tion time for providers charging a basic rate per connection.
361              e.g. hangup 3:5:60

START MODULE

365       isdnlog can react on any event and start programs. This feature is dis‐
366       abled unless you activate it with:
367
368       -S   start={yes|no}
369              active  "START"  feature.  Please read callerid.conf(5) for more
370              information.
371
372       closefds={yes|no}
373              (There is no commandline option  for  this.)   If  set  to  yes,
374              isdnlog  will  close  all  unnecessarily opened file descriptors
375              before a "START" program is executed.  This  closing  will  also
376              take place at isdnlog's restart after SIGHUP.  Default is no.
377

CONNECTION LOG MODULE

379       isdnlog  will  log  all  connections  in /var/log/isdn.log. isdnrep can
380       parse this file and calculate costs.
381

SEVERAL ISDN CARDS

383       If you have more than one isdn card, you need to run  one  isdnlog  for
384       each  card. And every process must have a different name, so you should
385       create a symbolic link isdnlog1 -> isdnlog, and start isdnlog1 for  the
386       second card.
387

UNLOADING KERNEL MODULES

389       You  cannot  unload isdn kernel modules while an isdn device is in use,
390       e.g. a PPP interface is defined or isdnlog is running. Look at /var/run
391       for  a file isdnlog.DEVICE.pid with the process id of isdnlog, and kill
392       that. After that you should be able to unload your isdn kernel modules.
393

FILES

395       /dev/DEVICE
396              isdnlog requires a device as a  parameter  to  read  from  (e.g.
397              /dev/isdnctrl0 for the 1st isdn card).
398
399       /tmp/DEVICE
400              isdnlog  can  copy  everything  it  reads  to this file as debug
401              information (e.g. /tmp/isdnctrl0 if  you  started  isdnlog  with
402              /dev/isdnctrl0).
403
404       /var/run/isdnlog.DEVICE.pid
405              isdnlog  creates this file with its process id. Useful to see if
406              isdnlog is running.
407
408       /var/lock/LCK..DEVICE
409              isdnlog creates a lock file for the device,  so  no  other  pro‐
410              cesses will access that device.
411
412       /etc/isdn/isdn.conf
413              isdnlog config file. Options to isdnlog can be given on the com‐
414              mand line, can be stored in this file in [options] (with command
415              line  option  -f/etc/isdn/isdn.conf),  or  in a different config
416              file, but isdnlog will look at this file for  sections  [global]
417              [variables] [isdnlog].
418

SIGNALS

420       SIGHUP (-1)
421              On  SIGHUP isdnlog restarts, and does therefore reread it's con‐
422              fig files.
423
424       SIGINT (-2), SIGTERM (-15), SIGQUIT (-3)
425              Isdnlog quits gracefully on receiving these termination signals.
426
427       SIGSEGV (-11)
428              If the log level contains 0x8000 (and your ulimits permit  this)
429              isdnlog will generate a core file before terminating.
430

EXAMPLE

432       I  start  isdnlog  with "isdnlog -f/etc/isdn/isdn.conf /dev/isdnctrl0".
433       This file contains a [options] section:
434
435       [options]
436       #newline=no     # show all throughput messages in one line.
437       #width=80       # limit log messages to 80 characters per line
438       #amt=0:80:81    # digits to get a line through your PABX
439       log=15          # maximum debug mode
440       flush=no        # flush logfile after every write
441       pipe=no         # pipe log messages to stderr
442       daemon=yes      # run isdnlog as daemon
443       stdout=0x1ff7   # stderr logging level
444       outfile=+/var/log/isdn.log               # log to file
445       #console=       # log to a console
446       monitor=yes     # emulate output for  imon/imontty/...
447       syslog=0x1ff7   # syslog logging level
448       #xisdn=0x07ff   # x11 output level
449       #calls=         # store call information for x11 client
450       #xlog=          # store messages for x11 client
451       thruput=60      # if throughput logging is enabled: log every X seconds
452       time=2          # set time: 0 = never; 1 = once; 2 = every time
453       #hangup=        # simulate charge signals
454       start=yes       # enable starting programs
