NAME

isdnlog - isdn log system (and more)

 

DESCRIPTION

RESTRICTION

GENERAL OPTIONS

-V

show version information and exit.

-fFILE

read options from the config file FILE. This file is also called the parameter file of isdnlog. 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 command line, they cannot be stored in a file.

/dev/DEVICE

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).

(There is no commandline option for this.) Overwrite area code from isdn.conf. A machine connected to subscriber lines with different area codes and thus several isdnlogs running requires this non global setting.

-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.

skipProv=skiplist

(There is no commandline option for this.) Ignore certain providers from the rate-file. The format of skiplist is the same as for Q: tags in rate.conf and described in rate.conf(5).

-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 calls.
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 leading 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 on your PABX.

-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[:y] ignoreCOLP=value[:value]

Ignore COLP/CLIP frames when value is 1 or greater.
Value 0 is default, and tells isdnlog to not ignore COLP/CLIP frames. With value 2 the ignored COLP/CLIP number is displayed.
The first value applies to COLP the second to CLIP. If only one value is given, it applies to COLP and CLIP.
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.

(There is no commandline option for this.) A PABX may cause numerous messages like "Unexpected discriminator 0x47 -- ignored!" resulting from protocol discriminator values in layer 3 not known to isdnlog. Set ignoreUPD to yes to suppress this messages.

-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 displayed.

Some setups may require workarounds for reliable logging. These workarounds are enabled by addition of the following numbers to the dual value. They are intended for the dualmode but may also be useful without. In this case, specify only the sum of the following numbers without 1 or 2 for the dual mode.

0x100

Enable this when the destination number of an outgoing call contains the number of the previous call, e.g. calling 222 after calling 111 before results in 111222 for the second call.

This may also help in situations where an unanswered incoming call causes incorrect logging of the following outgoing call.

0x200

Enable this when outgoing calls are logged without a source number (own MSN).

0x400

Enable this when unanswered incoming calls are logged multiple times (revealed by isdnrep -E).

-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

DEBUG MODULE

-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.

NUMBER REWRITE MODULE

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.

LOG MODULE

0x1

Errors

0x2

Warnings

0x4

Notice

0x8

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

0x10

Show telephone numbers immediately.

0x20

Show charge int and telephone costs with every charge signal (in Germany, and perhaps 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 signal -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 time.

-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 seconds.

-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.

LCR

-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 done.
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 'providerchange'

(There is no commandline option for this.) This script is called with 3 parameters, the new provider number (from 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.

TIME MODULE

-tX     time={0|1|2}

Isdnlog will set your local system time to the time transmitted by your
isdn service provider: -t1 = once, -t2 = every time.

CHARGEHUP MODULE

-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 seconds).

With this information, isdnlog will call "isdnctrl chargeint <device> <charge time>" and "isdnctrl huptimeout <device> <seconds before charge signal>" (it actually 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

START MODULE

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.

(There is no commandline option for this.) If set to yes, isdnlog will close all unnecessarily opened file descriptors before a "START" program is executed. This closing will also take place at isdnlog's restart after SIGHUP. Default is no.

CONNECTION LOG MODULE

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

FILES

/dev/DEVICE

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

/tmp/DEVICE

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

/var/run/isdnlog.DEVICE.pid

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

/var/lock/LCK..DEVICE

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

/etc/isdn/isdn.conf

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].

SIGNALS

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) isdnlog will generate a core file before terminating.

EXAMPLE

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

[options]
#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
#console=       # log to a console
monitor=yes     # emulate output for  imon/imontty/...
syslog=0x1ff7   # syslog logging level
#xisdn=0x07ff   # x11 output level
#calls=         # store call information for x11 client
#xlog=          # store messages for x11 client
thruput=60      # if throughput logging is enabled: log every X seconds
time=2          # set time: 0 = never; 1 = once; 2 = every time
#hangup=        # simulate charge signals
start=yes       # enable starting programs
