isdnrep - report isdn activity



Isdnrep reads the isdnlog log files, generates reports, does statistics, and other things. It can also generate HTML output for use with a web server.



show version information and exit.

-a      all
Show all connections registered. If this option is
not given, show only the connections made today.

-S      Summary
Show a summary (no individual calls) for selected date range. If this
option is given twice, the summaries per day are hidden too. Don't use with -h

-h      no header
There will be no header for each day, nor will the summary at the end
of each day and at the end of the report be generated. This is useful if the output is to be processed by another program.
This option doesn't work if the -wX is also given.

-n      numbers
Display numbers instead of the aliases for those numbers.

The file from which to generate the report. This is usually /var/log/isdn.log, or whatever is configured in /etc/isdn/isdn.conf as LOGFILE = . The -f option will override the setting in /etc/isdn/isdn.conf.

-t time span    time=time span
With this option a specific time span covered by the log file can be
displayed, e.g. all calls in November 1995, or on January 3rd 1996 between 03:00 and 09:45.

The format in which times are given is described below. The time span has the following syntax:

display from begin time up to end time
display from given time up to "now"
display from beginning of log file up to given time
display the given month, day, hour, ...

-d -time        delete=time
Delete entries from the log file up to (but not including) the specified
time. The format is the same as for the -t option. The minus before the time must be given! It is not possible to define begin and end times; entries are always deleted from the beginning up to the time given.

Warning! Entries are really deleted from the file. Careless use can result in all entries being deleted, e.g. with "isdnrep -d -".

-E      print Errors
Display all connections and connection attempts. Without this option,
only successful connections are displayed.

-v      verbose
Display warnings on startup.

-p [n][m]'number'[,[m]'number'...]      phonenumber
Display only selected phone numbers.

"number" is specified in the same format as in configuration files (see isdn.conf(5)). E.g. wildcards can be used.

If the flag 'm' is given, the corresponding MSN is meant. E.g.: "m2" means MSN#2. If "m0" is given, all numbers are to be displayed.

If the flag 'n' is given, the given number is not to be displayed.

-i      incoming
Only incoming connections are displayed.

-o      outgoing
Only outgoing connections are displayed.

-u      unknown caller
At the end of the report, all numbers not aliased in callerid.conf or
~/.isdn are displayed. This option is not available when HTML output is requested.

-wX     WWW
isdnrep can give its output in HTML format; this is switched on with
this option. Two modes are possible:

The HTML header is suppressed. Useful if the output is to be included into an existing page.
A complete HTML page is generated.

-sX     format string
The output generated by isdnrep can be modified by specifying the format
of the line generated for each connection. The syntax is similar to that used by printf. The following parameters are possible (the x where given means that a width for the field, also known as the precision, must be given):

time without date
e.g. 23:54:06
the date
e.g. 25/07/97
date without year
e.g. Sun May 04
year, in four digits
e.g. 1997
duration of connection
e.g. 00:03:34
the local MSN; if an alias can be found, that will be displayed instead
the local MSN, only as a number; no aliases will be substituted
the remote number; if an alias can be found, that will be displayed instead
the remote number, only as a number; no aliases will be substituted
the town corresponding to the local MSN if known; an empty string otherwise
the town corresponding to the remote number if known; an empty string otherwise
an arrow indicating the direction of the connection ("->" outgoing or "<-" incoming); the local MSN should be displayed on the left side of this.
an arrow indicating the direction of the connection, reversed ("<-" outgoing or "->" incoming); the local MSN should be displayed on the right side of this.
the charge units, if known
e.g. 6 EH
the cost, if known
e.g. 2,28 DM
amount of INPUT data
amount of OUTPUT data
INPUT throughput (bps)
OUTPUT throughput (bps)
Service Indicator
displays a HTTP link to the corresponding fax, when a fax was received by mgetty. This fax can be displayed by using the link in a HTTP browser.
This option is only valid when used with -wx, see below for more information.
displays a HTTP link to the corresponding voice file, when a call was recorded by vbox. This option is only valid when used with -wx, see below for more information.

The default format string for (non-HTML output) is

" %X %D %15.15H %T %-15.15F %7u %U %I %O"

With the following string all the important data is displayed while keeping the total length to 80:

"%X%D %10.10H%T%-14.14F%U%I %O"

The above string is put into isdn.conf at installation as REPFMTSHORT and can be used with -Fshort.

-FX    format
format strings can be specified in isdn.conf; this option
is used to select one of these. Entries can be defined in the section [ISDNLOG] with names beginning with "REPFMT". The string after the -F option is added to REPFMT to find the correct entry. Case is not sensitive. E.g.:

REPFMT1        = ... # -> isdnrep -F1
REPFMTMYSTRING = ... # -> isdnrep -Fmystring or
                          isdnrep -F MYSTRING



isdnrep can generate a HTML page containing links to files generated by vbox and mgetty (faxes), so that the messages and faxes can be heard or seen from within a browser. However, a couple of things need to be configured first.

answering machine messages

The %C can be used in the isdnrep output format to make a link to a voice recording file. For this to work, the following entry is needed in the [ISDNLOG] section in isdn.conf:

    VBOXPATH= /var/spool/vbox/fred/incoming # incoming directory pathname

Now isdnrep can find the file correctly. Clicking on this link will cause the file to be sent. These files are in ZyXEL format; the browser cannot use these directly. The type is given by isdnrep as follows:

    Content-Type: application/x-zyxel4

The correct application (helper) for this has to be configured in the browser. Alternatively, a conversion program can be specified to isdnrep which will convert the ZyXEL format. The pathname of the file to convert is given as a parameter to the program.

In the [ISDNLOG] section of isdn.conf an entry as follows specifies which conversion program to use:

    VBOXCMD1 = /usr/bin/program1

for versions 0.x and 1.x of vbox, and

    VBOXCMD2 = /usr/bin/program2

for versions 2.x of vbox. Both entries can be given, isdnrep recognizes which version created the recording.

The program must first output a line with the content-type, followed by the data itself. To convert the ZyXEL format into a WAV file, the following script may be used:

#! /bin/sh
## script to play voice messages from vbox-2.0
## WARNING! If the paths are not set correctly,
## netscape may simply crash!

PATH=$PATH:"path to sox":"path to pvftools":"path to vbox"

vboxtoau <$1             | \
          autopvf        | \
          pvfamp $VOLUME | \
          pvfcut 0.20    | \
                pvftovoc > $FILENAME1


echo Content-Type: audio/x-wav


The script above needs the packages sox and pvftools. Additionally, the browser needs to be told how to handle "audio/x-wav". This is done by adding the following lines to the files listed:

type=audio/x-wav \ desc="auWAV Audio" \ exts="wav"
audio/x-wav;/usr/bin/auplay %s

The package NAS (Network Audio System) may be needed.

Now, when the browser is started, it will recognize WAV files and start the corresponding program to handle these. The WAV format has been chosen as this can also be played from a Windows pc.

faxes received by mgetty

When %G is used in the isdnrep output format, any faxes received by mgetty will be accessible via a HTML link, in the same manner as the ansering machine messages.

For the faxes the following entry in the [ISDNLOG] section in isdn.conf is needed:

    MGETTYPATH = /var/spool/fax/incoming

WARNING: if isdnrep doesn't have permission to read the files, they will not be displayed; there will be no error message.

When isdnrep passes these files back to the browser, they have the G3 format. The following header is used to notify the browser of this:

    Content-Type: application/x-faxg3

As the browser probably doesn't understand this format, the following changes to the files listed are needed:

type=application/x-faxg3 \ desc="G3-Fax Format" \ exts="fax,g3"
pplication/x-faxg3;/usr/X11/bin/g3view %s

The program g3view has to be installed for this to work.

If now the link is clicked on, the browser will automatically start the external g3view to handle this data.

If you prefer another format (instead of G3) such as JPEG, the format has to be converted. The following entry in the [ISDNLOG] section of isdn.conf takes care of this:

VBOXCMD = /usr/bin/g3tojpeg # example

The script g3tojpeg can be something like this:

#! /bin/sh
## command to display faxes in a browser
## WARNING! If the paths are not set correctly,
## netscape may simply crash!

export PATH=$PATH:"path to g3topbm":"path to convert"

echo Content-Type: image/jpeg

g3topbm < $1 | convert pbm:- jpeg:-

The packages ImageMagick and mgetty are needed. Mgetty is probably already installed if you want to use this feature :-)

The advantage of the JPEG format is that it can also be displayed by a browser running on a Windows pc.


A suitable value for REPFMTWWW is

    REPFMTWWW = "%X %D %17.17H %T %-17.17F %-20.20l SI: %S %9u %U %I %O %G %C"

Netscape 3.0 Gold and Arena have been tested, and both work fine with isdnrep's HTML output, although Arena's display is not as colourful as Netscape's.

A known problem (which is impossible to solve completely) is determining the relationship between an isdn connection and a fax or vbox recording. Unfortunately the times for isdnrep, mgetty and vbox differ. Isdnrep tries to make the best guess, but it's always possible that e.g. a fax is connected to the wrong isdn connection.



With the default configuration the following output can be generated on stdout (whitespace slightly edited for clarity):
