isdnlog
isdnlog(8) Linux System Administration isdnlog(8) NAME isdnlog - isdn log system (and more) DESCRIPTION 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). RESTRICTION 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. tele phones), 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). GENERAL OPTIONS -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 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 sec ond). 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 preselectio 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 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 nor malized 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 one your PABX -o other={yes|no} Normally "causes" (e.g. "non-selected user clear ing") for other connected ISDN devices are not dis played, only those which are related to the connec tion 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 Manage ment 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 differ ent 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 sec ond 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 out put - every single digit will be displayed. -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 num bers 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 pro cessing 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), give this flag, or isdnlog will show the own MSN's incorrectly. NUMBER REWRITE MODULE You can define aliases for telephone numbers (see cal lerid.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 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 coun tries, 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 mes sages. -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: 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' providerchange="path_top_script" (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. 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 calcu late 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 sec ond 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, with out 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 tele phone 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 cal lerid.conf(5) for more information. CONNECTION LOG MODULE isdnlog will log all connections in /var/log/isdn.log. isdnrep can parse this file and calculate costs. SEVERAL ISDN CARDS If you have more than one isdn card, you need to run one isdnlog for each card. And every process must have a dif ferent name, so you should create a symbolic link isdnlog1 -> isdnlog, and start isdnlog1 for the second card. UNLOADING KERNEL MODULES 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. 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. Use ful 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 sec tions [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 termi nation signals. SIGSEGV (-11) If the log level contains 0x8000 (and your ulimits permit this) isdlog will generate a core file before terminating. EXAMPLE I start isdnlog with "isdnlog -f/etc/isdn/isdn.conf /dev/isdnctrl0".
