.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility is part of the isdn4bsd package and is used to provide the user with a
|
|
mnemonic display of the layers 1, 2 and 3 protocol activities on
|
|
the D channel and hex dump of the B channel(s) activities.
|
|
.Pp
|
|
Together with two passive supported cards and an easy to build cable it can
|
|
also be used to monitor the complete traffic on a S0 bus providing S0 bus
|
|
analyzer features.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility is only available for passive supported cards.
|
|
.Pp
|
|
.Em Note
|
|
.Pp
|
|
All filenames, user specified or default, get a date and time stamp string
|
|
added in the form -yyyymmdd-hhmmss: a hyphen, four digits year, two digits
|
|
month and day, a hyphen and two digits hour, minutes and seconds.
|
|
Tracefiles no longer get overwritten.
|
|
In case a new filename is needed within a second, the filename-generating
|
|
mechanism sleeps one second.
|
|
.Pp
|
|
In case the program is sent a USR1 signal, a new user specified or default
|
|
filename with a new date and timestamp is generated and opened.
|
|
.Pp
|
|
The following options can be used:
|
|
.Bl -tag -width Ds
|
|
.It Fl a
|
|
Run
|
|
.Nm
|
|
in analyzer mode by using two passive cards and a custom cable which can
|
|
be build as described in the file
|
|
.Em cable.txt
|
|
in the isdn4bsd source distribution.
|
|
One card acts as a receiver for the
|
|
transmitting direction on the S0 bus while the other card acts as a receiver
|
|
for the receiving direction on the S0 bus.
|
|
Complete traffic monitoring is
|
|
possible using this setup.
|
|
.It Fl b
|
|
switch B channel tracing on (default off).
|
|
.It Fl d
|
|
switch D channel tracing off (default on).
|
|
.It Fl f
|
|
Use
|
|
.Ar filename
|
|
as the name of a file into which to write tracing output (default filename is
|
|
isdntrace<n> where n is the number of the unit to trace).
|
|
.It Fl h
|
|
switch display of header off (default on).
|
|
.It Fl i
|
|
print layer 1 (I.430) INFO signals to monitor layer 1 activity (default off).
|
|
.It Fl l
|
|
switch displaying of Layer 2 (Q.921) frames off (default on).
|
|
.It Fl n
|
|
This option takes a numeric argument specifying the minimum
|
|
frame size in octets a frame must have to be displayed.
|
|
(default 0)
|
|
.It Fl o
|
|
switch off writing trace output to a file (default on).
|
|
.It Fl p
|
|
Use
|
|
.Ar filename
|
|
as the name of a file used for the -B and -P options (default filename
|
|
is isdntracebin<n> where n is the number of the unit to trace).
|
|
.It Fl r
|
|
Switch off printing a raw hexadecimal dump of the packets preceding
|
|
the decoded protocol information (default on).
|
|
.It Fl u
|
|
Use
|
|
.Ar number
|
|
as the unit number of the controller card to trace (default 0).
|
|
.It Fl x
|
|
Switch on printing of packets with a non-Q.931 protocol discriminator.
|
|
(default off).
|
|
.It Fl B
|
|
Write undecoded binary trace data to a file for later or remote
|
|
analyzing (default off).
|
|
.It Fl F
|
|
This option can only be used when option -P (playback from binary data file)
|
|
is used.
|
|
The -F option causes playback not to stop at end of file but rather
|
|
to wait for additional data to be available from the input file.
|
|
.Pp
|
|
This option is useful when trace data is accumulated in binary format (to
|
|
save disk space) but a monitoring functionality is desired.
|
|
(default off).
|
|
.It Fl P
|
|
Read undecoded binary trace data from file instead from device (default off).
|
|
.It Fl R
|
|
Use
|
|
.Ar unit
|
|
as the receiving interface unit number in analyze mode.
|
|
.It Fl T
|
|
Use
|
|
.Ar unit
|
|
as the transmitting interface unit number in analyze mode.
|
|
.El
|
|
.Pp
|
|
When the USR1 signal is sent to a
|
|
.Nm
|
|
process, the currently used logfiles are reopened, so that logfile
|
|
rotation becomes possible.
|
|
.Pp
|
|
The trace output should be obvious.
|
|
It is very handy to have the following
|
|
standard texts available when tracing ISDN protocols:
|
|
.Pp
|
|
.Bl -tag -width Ds -compact -offset indent
|
|
.It Ar I.430
|
|
ISDN BRI layer 1 protocol description.
|
|
.It Ar Q.921
|
|
ISDN D-channel layer 2 protocol description.
|
|
.It Ar Q.931
|
|
ISDN D-channel layer 3 protocol description.
|
|
.It Ar 1TR6
|
|
German-specific ISDN layer 3 protocol description.
|
|
(NOTICE: decoding
|
|
of the 1TR6 protocol is included but not supported since i dont have
|
|
any longer access to a 1TR6 based ISDN installation.)
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility
|
|
automatically detects the layer 3 protocol being used by looking at the
|
|
Protocol Discriminator (see: Q.931/1993 pp.\& 53).
|
|
.Sh FILES
|
|
.Bl -tag -width daddeldi -compact
|
|
.It Pa /dev/i4btrc<n>
|
|
The devicefile(s) used to get the trace messages for ISDN card unit <n>
|
|
out of the kernel.
|
|
.El
|
|
.Sh EXAMPLES
|
|
The command:
|
|
.Bd -literal -offset indent
|
|
isdntrace -f /var/tmp/isdn.trace
|
|
.Ed
|
|
.Pp
|
|
will start D channel tracing on passive controller 0 with all except B
|
|
channel tracing enabled and logs everything into the output file
|
|
/var/tmp/isdn.trace-yyyymmdd-hhmmss (where yyyymmdd and hhmmss are replaced
|
|
by the current date and time values).
