       isdnlog - isdn log system (and more)

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

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

       -V     show version information and exit.

       -fFILE read  options from the config file FILE.	The first line should be "[options]". You
	      may use blank lines and comments (starting with a #).  All config files for isdnlog
	      have the format described in isdn.conf(5).  Debug options must be given on the com-
	      mand line, they cannot be stored in a file.

	      isdnlog will read  from  this  device  and  from	/dev/isdninfo.	You  should  give
	      /dev/isdnctrl0 for the first isdn card (or /dev/isdnctrl2 for the second).

	      Isdnlog  has  a replay mode for debugging, where you can simulate previous recorded
	      events. In that case use "-" instead of a device.

       -Ax  amt="value"
	      Set digits necessary to get an outside line, when connected through  a  PABX.   You
	      can give several codes padded with a ":" (e.g. -A0:80:81:82).

       -Bvbn	 vbn="value"
	      Set the provider preselection to the given value. More prefixes may be separated by
	      a ":".
	      Values are e.g. "010" for DE, "10" for AT, "16:17" for NL, "9" for FR.

       -Rprefix  preselected="value"
	      Set the preselected (i.e the provider choosen, if no prefix is dialed) provider  to
	      value. Value should be without vbn.

       -0x:y	 trim="value[:value]"
	      Suppress	leading  digits.  If isdnlog is connected through a PABX, it is sometimes
	      not possible to let isdnlog distinguish between a  national  and	an  international
	      call, even with help of the -A option.
	      This  option  requires  two  values separated with ":" as an argument. These values
	      tell isdnlog how many leading digits to remove from  incoming  and  outgoing  calls
	      respectively. If only one value is given, it is used for both incoming and outgoing
	      Don't use this in combination with the -A option! This will confuse the system (and
	      possibly you).

	      Example:	a  PABX  in  Germany shows the number of an incoming call from Hamburg as
	      "00040...".  When calling out to Hamburg, it shows the number as	"0040...".   This
	      means  that  on incoming calls, three zeroes must be removed, and on outgoing calls
	      two zeroes must be removed (the number must be normalized to be without any leading
	      zeroes  in the case of a national number; international numbers must have one lead-
	      ing zero). So, in this case, the option -03:2 would be correct.

       -ix  internS0="value"
	      Telefon number shorter then value are considered to be internal  numbers	one  your

       -o   other={yes|no}
	      Normally	"causes"  (e.g.  "non-selected	user  clearing") for other connected ISDN
	      devices are not displayed, only those which are related to the connection  will  be
	      shown. With this option the causes for the other devices are also displayed.

       -ux  ignoreRR="value"
	      Ignore  "housekeeping"  frames.  x may be 1 (ignore RR=Receiver ready) or 2 (ignore
	      EMP=Euracom Management Protokoll) frames.

       -Ux  ignoreCOLP="value"
	      Ignore COLP/CLIP frames when value is 1.	Value 0 is default, and tells isdnlog  to
	      not ignore COLP/CLIP frames.
	      Sometimes  the  COLP  number is a number in a different areacode to the number that
	      was dialled, and then the cost calculation would be wrong.

       -2x  dual="value"
	      Enable dual mode. You need this if you  have  a  second  isdn  card  attached  with
	      crossed  lines  so  it  can  listen  to what other isdn devices like telephones are
	      doing. With x=2 you can increase the debug output - every single digit will be dis-

       -1     A HFC-based card is used for echo mode. Enable echo mode for the HFC card with
	      hisaxctrl id 10 1
	      hisaxctrl id 12 1

       -r     Replay  a  debug file (e.g. /tmp/isdnctrl0) to find bugs. With this flag you should
	      give a filename with the debug information instead of a device.  It will also  work
	      with files not created by isdnlog (e.g.  "cat /dev/isdnctrl0").

       -n   newline={yes|no}
	      Display throughput messages on the same line (only useful with logging to stderr or
	      a console device).

       -WX  width="value"
	      Limit all messages to X characters per line.

       -vX  log=X
	      Isdnlog can copy all information to /tmp/DEVICE (e.g. /tmp/isdnctrl0 if you started
	      isdnlog  with  /dev/isdnctrl0).  Choose  what debugging you want from the following
	      list, add the corresponding numbers together and use that for X:

	      1      copy all "HEX:" lines from the hisax isdn device driver.
	      2      copy /dev/isdnctrl output (or whatever device you specified).
	      4      copy /dev/isdninfo output
	      8      copy transfer values ("ibyte","obyte").

	      Isdnlog will close and reopen this file after a "kill -HUP".

       -s   flush={yes|no}
	      Isdnlog will flush the debug file  /tmp/DEVICE  (e.g.  /tmp/isdnctrl0)  after  each
	      write access.

       -P   pipe={yes|no}
	      Copy the debug information to stdout. This way you can run isdnlog as the source of
	      a pipe like "isdnlog -P /dev/isdnctrl0 |prog ... ".

       -D   daemon={yes|no}
	      Start isdnlog as daemon: it will fork into the background, and use  syslog  as  the
	      default logging method (if you did not specify -m).

       -T     Trace mode: isdnlog will wait for a key after processing a line from /dev/isdnctrl0
	      (or whatever device you specified).

       -K     Print for every pressed key the thruput. Can not used together with option -d.

       -b     If you are using a bilingual network terminator (NT), you must give this	flag,  or
	      isdnlog will show the own MSN's incorrectly.

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

       Isdnlog	can  log  information via syslog, to stdout, and send information to x11 clients.
       Calculate a code from these numbers by adding them, and activate logging with  -s,  -m  or
       -x.  You  can  use normal numbers or hex numbers. Default is stderr mode -m, unless daemon
       mode is enabled; then it's syslog mode -l.

       0x1    Errors

       0x2    Warnings

       0x4    Notice

       0x8    Log messages to  /tmp/DEVICE  (e.g.  /tmp/isdnctrl0  if  isdnlog	is  started  with

       0x10   Show telephone numbers immediately.

       0x20   Show  charge int and telephone costs with every charge signal (in Germany, and per-
	      haps other countries, you have to pay to get these signals).

       0x40   Show connect messages.

       0x80   Show hang up messages.

       0x100  Show cause message on hang up.

       0x200  Show time messages.

       0x400  Show throughput in bytes (every -wX seconds).

       0x800  Show state of B-channels (use with -M monitor).

       0x1000 Show service indicator.
	      You should log at least 0x7 (errors, warnings, notice) messages.

       0x2000 Log estimated time till next charge signal.

       0x4000 Show chargemax.

       0x8000 Enable core file on SIGSEGV.

       0x10000 ... 0x800000, show more diagnostic and debug messages.

       -mX  stdout="value"
	      Log to stderr.

       -OX  outfile="path"
	      Log to file X instead of stderr. Isdnlog will close this device when it gets a sig-
	      nal -SIGHUP (-1). Only valid with -m option.
	      If  the  name  starts  with  a "+", new data will be appended to the existing file.
	      Default behaviour is to truncate the file when isdnlog opens it.

       -C X	 console="path"
	      Log to console X instead of stderr. You can use -O and -C together, so that isdnlog
	      copies  output  to  both.  Specify  a  full pathname.  Beware: you must put a space
	      between -C and X !

       -M   monitor={yes|no}
	      With this flag, isdnlog will  generate  output  for  monitor  programs  like  imon,
	      imontty or isdnmon. You must also give -m with 0x800 enabled.

       -lX  syslog="value"
	      Log  to  syslog. X is the log code. You can log to syslog and to stdout at the same

       -xX  xisdn="value"
	      Pass information to x11 client. X is the log code. You can pass information to  x11
	      clients and log to syslog and/or stdout at the same time.

       -pPORT port="value"
	      Pass information to x11 client on this PORT.

       -cX  calls="value"
	      Only  with  -xX : save the last X calls and pass this information to an x11 client.
	      Default value is 100.

       -LX  xlog="value"
	      Only with -xX : save the last X messages	and  pass  this  information  to  an  x11
	      client. Default value is 500.

       -wX  thruput="value"
	      If  you enabled throughput logging (0x400), isdnlog will log the throughput every X

       -Ix:y	 ciinterval="value[:value]"
	      Interval for printing of charge messages (0x20).
	      The first value is the interval for the calculated CI, the second value for the  EH
	      (AOC-D) messages. If only one value is given, both intervals are set to this value.

       -dx  abclcr="value"
	      Value is a bitmap:
	      0 ... off
	      1 ... calls to different area / country
	      2 ... local calls too
	      4 ... special numbers e.g. ISP
	      This needs a kernel patch to work. If the kernel patch is not found a simulation is
	      Note: depending on your telefon provider local area calls may or may not be  routed
	      to  alternate  providers.   For changing the ISP a script is called. s. next option

	      (There is no commandline option for this) This script is called with 3  parameters,
	      the  new	provider number (fron rate-CC.dat) the number, which would be dialed, and
	      the servicename.	The script should adjust routing, name resolution and  so  on  to
	      connect to the ISP.  If the script returns non zero, LCR will not be done.

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

       -hX  hangup="value"
	      The isdn kernel system has a chargehup system, so it will hang  up  a  few  seconds
	      before  the  next  charge  signal. If you don't get a charge signal from your phone
	      company, isdnlog can emulate it.

	      On every outgoing connection, isdnlog will calculate the charge time  from  day  of
	      week, time of day and the distance zone of the connection.

	      The  kernel  needs to know how long the charge time is, and how many seconds before
	      the next charge signal it should hang up. You have to set the second parameter with
	      X  in  the form number:number (hang up seconds before next charge signal for charge
	      times greater than or equal to 20 seconds : for charge times of less than  20  sec-

	      With  this  information,	isdnlog  will  call  "isdnctrl chargeint <device> <charge
	      time>" and "isdnctrl huptimeout <device> <seconds before charge signal>" (it  actu-
	      ally communicates directly with isdn, without calling isdnctrl, but this would have
	      the same effect).

	      You should run isdnlog with -t1 or better with -t2, so isdnlog sets the local  time
	      in sync with telephone switching office.

	      If  there  is  a	third  number  in  value, this is the minimum connection time for
	      providers charging a basic rate per connection.
	      e.g. hangup 3:5:60

       isdnlog can react on any event and start programs. This feature	is  disabled  unless  you
       activate it with:

       -S   start={yes|no}
	      active "START" feature. Please read callerid.conf(5) for more information.

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

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

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

	      isdnlog requires a device as a parameter to read from (e.g.  /dev/isdnctrl0 for the
	      1st isdn card).

	      isdnlog can copy everything it reads  to	this  file  as	debug  information  (e.g.
	      /tmp/isdnctrl0 if you started isdnlog with /dev/isdnctrl0).

	      isdnlog creates this file with its process id. Useful to see if isdnlog is running.

	      isdnlog  creates a lock file for the device, so no other processes will access that

	      isdnlog config file. Options to isdnlog can be given on the command  line,  can  be
	      stored  in this file in [options] (with command line option -f/etc/isdn/isdn.conf),
	      or in a different config file, but isdnlog will look  at	this  file  for  sections
	      [global] [variables] [isdnlog].

       SIGHUP (-1)
	      On SIGHUP isdnlog restarts, and does therefore reread it's config files.

       SIGINT (-2), SIGTERM (-15), SIGQUIT (-3)
	      Isdnlog quits gracefully on receiving these termination signals.

       SIGSEGV (-11)
	      If  the log level contains 0x8000 (and your ulimits permit this) isdlog will gener-
	      ate a core file before terminating.

       I start isdnlog with "isdnlog -f/etc/isdn/isdn.conf /dev/isdnctrl0".  This file contains a
       [options] section:

       #newline=no     # show all throughput messages in one line.
       #width=80       # limit log messages to 80 characters per line
       #amt=0:80:81    # digits to get a line through your PABX
       log=15	       # maximum debug mode
       flush=no        # flush logfile after every write
       pipe=no	       # pipe log messages to stderr
       daemon=yes      # run isdnlog as daemon
       stdout=0x1ff7   # stderr logging level
       outfile=+/var/log/isdn.log		# log to file

       thruput=60      # if throughput logging is enabled: log every X seconds
       time=2	       # set time: 0 = never; 1 = once; 2 = every time
