Combine Wireshark Summary and Detail Information with XML Joins

Filed under: Code, Network — Tags: , , , , — networknerd @ 8:45 am

Wireshark users may occasionally find themselves wishing for the ability the add some packet detail to the summary information. In the previous post I was looking at DSCP  and TOS information and wanted to add that to the summary rather than drilling down into every packet.  The first solution is to use Tshark and a lua script as I did in the previous post.  The second solution is to export the capture file in both PSML and PDML format packet detail and render them in a web browser.

PSML and PDML are both XML files, so they can be rendered using an XML stylesheet and displayed in a web browser. Sensibly parsing the output of two different XML files can be a bit tricky. Fortunately there is a common field in each file, the packet number, which can be used to perform the equivalent of an SQL join on the two files.

First I captured the request and response of two single pings, one with and one without the ToS byte set.  Then I exported the files in PDML and PSML formats as shown below.  Note the reference in line 2 of packetsumm2.xml to the stylesheet table7.xsl.  When using a browser to transform the xml we have to modify it manually to include the reference rather than pass it as a command line parameter like we would with saxon or xalan.

The important parts of the stylesheet are highlighted in red.  The first of the highlighted lines creates a reference to the document element of the packet details file. The template below does all the hard work of performing the join.

<xsl:template match="/psml/packet">
      <tr>
  <xsl:variable name="packetnum" select="section[1]"/>
  <xsl:for-each select="section">
    <xsl:if test="position()=last()">
        <td><xsl:value-of select= "$packetdetail/pdml/packet/proto[@name = 'geninfo']/field[@name = 'num' and @show = $packetnum]/../../proto[@name = 'ip']/field[@name='ip.dsfield']/@showname"/></td>
    </xsl:if>
    <td><xsl:value-of select="."/></td>
  </xsl:for-each>
      </tr>
</xsl:template>

The packet number is in the first element and is saved in the variable packetnum.  A for-each  loop is created to output all the section elements of the packet summary.  In this case they are “No.”,  “Time”,  ” Source”,  ” Destination”,  ” Protocol” and  “Info”. As the loop progresses we test to see if we are at the last “section” element, and if we are it inserts the DS field information from the packet detail file. Now this is where the going gets heavy. We insert the DS field information using a <xsl:value-of> tag,  which contains a select attribute with an xpath expression to that information.

There are two main parts to this xpath expression

  1. $packetdetail/pdml/packet/proto[@name = 'geninfo']/field[@name = 'num' and @show = $packetnum]/
  2. ../../proto[@name = 'ip']/field[@name='ip.dsfield']/@showname

Part 1 drills down to the proto element of the packet that has  a field element with a name attribute equal to num and a show attribute equal to the packetnum variable.  This is the common part where we perform the join on the two files.

Part 2 solves the problem of accessing the DS field information.  This is a problem because our xpath expression has already taken us down one proto element and we need to be in another proto element at the same level. To get there we need to go back to the common ancestor of the two proto elements, using the ../.. expression and then match the proto element with a name attribute of ip and field element with a name attribute of ip.dsfield and finally selecting the showname attribute.

Conclusion

I admit the example using wireshark is a little contrived.  However, the ability to join xml files on a common field is a powerful technique worth keeping in the toolkit.  Who knows somebody may actually wish to display packet capture information in a web browser.
