isdnlog - isdn log system (and more)
Isdnlog gets information from your isdn card, decodes this
information, and can do anything 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 outgoing calls from any
device (see dual option below).
- -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).
- areacode="value"
- (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 provider (i.e the chosen provider, if no prefix is
dialed) 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.
- ignoreUPD={yes|no}
- (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
- -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 /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.
- -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'
- providerchange="path_top_script"
- (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.
- -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.
- -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
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.
- closefds={yes|no}
- (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.
isdnlog will log all connections in /var/lib/isdn/calls. 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.
- /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].
- 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.
I start isdnlog with "isdnlog -f/etc/isdn/isdn.conf
/dev/isdnctrl0". This file contains a [options] section:
[options]
