<title>History</title>
|
||||
<para>SIMtrace was created out of necessity. Harald Welte wanted
|
||||
to see the communication between a GSM Mobile Station (or
|
||||
what we call a cellphone) and the SIM. He was not able to
|
||||
find an existing solution, or the existing ones had mayor
|
||||
drawbacks that made using them very time consuming and slow.
|
||||
The Atmel AT91SAM7 came to the rescue. This microcontroller
|
||||
has hardware support for the ISO7816 T0/T1 Smart Card
|
||||
specification. Using this hardware with the clock coming from
|
||||
the normal connection we are able to read bytes coming from
|
||||
and going to the SIM.
|
||||
The next step in the project was taken by Kevin Redon
|
||||
that started to modify an existing AT91SAM7 design, started
|
||||
to use the Free Software KiCAD CAD Software. In 2011 the project
|
||||
went from having Schematics to having routed circuits, prototypes
|
||||
and the final product. The first production run was in August.</para>

<para></para>
|

<para>The setup of SIMtrace consists out of a Hardware and a
|

Software part. The SIM card needs to be put into the SIMtrace
|
||||
Hardware, the flex cable needs to be connected to the SIMtrace
|
||||
Hardware and the SIM end needs to be placed in the SIM socket
|
||||
of the phone. The SIMtrace hardware can be seen as a USB device
|
||||
from the host, the SIMtrace software will try to find this device
|
||||
and claim it. The SIMtrace software will receive packets from the
|
||||
SIMtrace hardware and can forward them using the GSMTAP protocol
|
||||
to the IANA assigned GSMTAP port (4729). A modified version of Wireshark
|
||||
can be used to analyze the data.</para>

.SH DESCRIPTION
|
||||
This manual page documents briefly the
|
||||
.B simtrace
|
||||
command.
|
||||
.PP
|
||||
.\" TeX users may be more comfortable with the \fB<whatever>\fP and
|
||||
.\" \fI<whatever>\fP escape sequences to invode bold face and italics,
|
||||
.\" respectively.
|
||||
\fBsimtrace\fP is a utility that communicates with the sysmocom SIMtrace
|
||||
hardware and forwards messages coming from the USB device to IP using
|
||||
the GSMtap protcol. The wireshark utility contains a protocol analyzer.
|
||||
.SH OPTIONS
|
||||
This program follows the usual GNU command line syntax, with long
|
||||
options starting with two dashes (`-').
|
||||
.TP
|
||||
.B \-h, \-\-help
|
||||
Show summary of options.
|
||||
.TP
|
||||
.B \-iIP, \-\-gsmtap-ip=IP
|
||||
The destination IP address for the SIM PDUs encapsulated in the GSMtap
|
||||
protocol.
|
||||
.TP
|
||||
.B \-a, \-\-skip\-atr
|
||||
Skip the ATR of the SIMcard.
