Two things:
1. You do need a late "LAN products cumulative patch" (e.g. PHNE_18173

-<a name="rfc.section.1"></a><h3>1. Objectives</h3>
-
-<p>The problem of exchanging packet traces becomes more and more critical every day; unfortunately, no standard solutions exist for this task right now. One of the most accepted packet interchange formats is the one defined by libpcap, which is rather old and does not fit for some of the nowadays applications especially in terms of extensibility.
-</p>
-<p>This document proposes a new format for dumping packet traces. The following goals are being pursued:
-</p>
-<ul class="text">
-<li>Extensibility: aside of some common functionalities, third parties should be able to enrich the information embedded in the file with proprietary extensions, which will be ignored by tools that are not able to understand them.
-</li>
-<li>Portability: a capture trace must contain all the information needed to read data independently from network, hardware and operating system of the machine that made the capture.
-</li>
-<li>Merge/Append data: it should be possible to add data at the end of a given file, and the resulting file must still be readable.
-</li>
-</ul>

-<a name="rfc.section.2"></a><h3>2. General File Structure</h3>
-
-<a name="rfc.section.2.1"></a><h4><a name="sectionblock">2.1</a> General Block Structure</h4>
-
-<p>A capture file is organized in blocks, that are appended one to another to form the file. All the blocks share a common format, which is shown in <a href="#formatblock">Figure 1</a>.
-</p><br /><hr />

-
-<p>The fields have the following meaning:
-</p>
-<ul class="text">
-<li>Block Type (32 bits): unique value that identifies the block. Values whose Most Significant Bit (MSB) is equal to 1 are reserved for local use. They allow to save private data to the file and to extend the file format.
-</li>
-<li>Block Total Length: total size of this block, in bytes. For instance, a block that does not have a body has a length of 12 bytes.
-</li>
-<li>Block Body: content of the block.
-</li>
-<li>Block Total Length: total size of this block, in bytes. This field is duplicated for permitting backward file navigation.
-</li>
-</ul>
-<p>This structure, shared among all blocks, makes easy to process a file and to skip unneeded or unknown blocks. Blocks can be nested one inside the others (NOTE: needed?). Some of the blocks are mandatory, i.e. a dump file is not valid if they are not present, other are optional.
-</p>
-<p>The structure of the blocks allows to define other blocks if needed. A parser that does non understand them can simply ignore their content.
-</p>
-<a name="rfc.section.2.2"></a><h4><a name="anchor3">2.2</a> Block Types</h4>
-
-<p>The currently defined blocks are the following:
-</p>
-<ol class="text">
-<li>Section Header Block: it defines the most important characteristics of the capture file.
-</li>
-<li>Interface Description Block: it defines the most important characteristics of the interface(s) used for capturing traffic.
-</li>
-<li>Packet Block: it contains a single captured packet, or a portion of it.
-</li>
-<li>Simple Packet Block: it contains a single captured packet, or a portion of it, with only a minimal set of information about it.
-</li>
-<li>Name Resolution Block: it defines the mapping from numeric addresses present in the packet dump and the canonical name counterpart.
-</li>
-<li>Capture Statistics Block: it defines how to store some statistical data (e.g. packet dropped, etc) which can be useful to undestand the conditions in which the capture has been made.
-</li>
-<li>Compression Marker Block: TODO
-</li>
-<li>Encryption Marker Block: TODO
-</li>
-<li>Fixed Length Marker Block: TODO
-</li>
-</ol>
-<p>The following blocks instead are considered interesting but the authors believe that they deserve more in-depth discussion before being defined:
-</p>
-<ol class="text">
-<li>Further Packet Blocks
-</li>
-<li>Directory Block
-</li>
-<li>Traffic Statistics and Monitoring Blocks
-</li>
-<li>Alert and Security Blocks
-</li>
-</ol>
-<p>TODO Currently standardized Block Type codes are specified in Appendix 1.
-</p>
-<a name="rfc.section.2.3"></a><h4><a name="anchor4">2.3</a> Block Hierarchy and Precedence</h4>
-
-<p>The file must begin with a Section Header Block. However, more than one Section Header Block can be present on the dump, each one covering the data following it till the next one (or the end of file). A Section includes the data delimited by two Section Header Blocks (or by a Section Header Block and the end of the file), including the first Section Header Block.
-</p>
-<p>In case an application cannot read a Section because of different version number, it must skip everything until the next Section Header Block. Note that, in order to properly skip the blocks until the next section, all blocks must have the fields Type and Length at the beginning. This is a mandatory requirement that must be maintained in future versions of the block format.
-</p>
-<p><a href="#fssample-SHB">Figure 2</a> shows two valid files: the first has a typical configuration, with a single Section Header that covers the whole file. The second one contains three headers, and is normally the result of file concatenation. An application that understands only version 1.0 of the file format skips the intermediate section and restart processing the packets after the third Section Header.

-</p>
-<a name="rfc.section.2.4"></a><h4><a name="anchor5">2.4</a> Data format</h4>
-
-<p>Data contained in each section will always be saved according to the characteristics (little endian / big endian) of the dumping machine. This refers to all fields that are saved as numbers and that span over two or more bytes.
-</p>
-<p>The approach of having each section saved in the native format of the generating host is more efficient because it avoids translation of data when reading / writing on the host itself, which is the most common case when generating/processing capture dumps.
-</p>
-<p>TODO Probably we have to specify something more here. Is what we're saying enough to avoid any kind of ambiguity?.

-
-<p>The Section Header Block does not contain data but it rather identifies a list of blocks (interfaces, packets) that are logically correlated. This block does not contain any reference to the size of the section it is currently delimiting, therefore the reader cannot skip a whole section at once. In case a section must be skipped, the user has to repeatedly skip all the blocks contained within it; this makes the parsing of the file slower but it permits to append several capture dumps at the same file.
-</p>
-<a name="rfc.section.3.2"></a><h4><a name="sectionidb">3.2</a> Interface Description Block (mandatory)</h4>
-
-<p>The Interface Description Block is mandatory. This block is needed to specify the characteristics of the network interface on which the capture has been made. In order to properly associate the captured data to the corresponding interface, the Interface Description Block must be defined before any other block that uses it; therefore, this block is usually placed immediately after the Section Header Block.
-</p>
-<p>An Interface Description Block is valid only inside the section which it belongs to. The structure of a Interface Description Block is shown in <a href="#formatidb">Figure 4</a>.

-<p>The Simple Packet Block is a lightweight container for storing the packets coming from the network. Its presence is optional.
-</p>
-<p>A Simple Packet Block is similar to a Packet Block (see <a href="#sectionpb">Section 3.3</a>), but it is smaller, simpler to process and contains only a minimal set of information. This block is preferred to the standard Packet Block when performance or space occupation are critical factors, such as in sustained traffic dump applications. A capture file can contain both Packet Blocks and Simple Packet Blocks: for example, a capture tool could switch from Packet Blocks to Simple Packet Blocks when the hardware resources become critical.
-</p>
-<p>The Simple Packet Block does not contain the Interface ID field. Therefore, it must be assumed that all the Simple Packet Blocks have been captured on the interface previously specified in the Interface Description Block.

Therefore, each tool can be either read the content of the optional fields (if any), or skip them at once.

-<li>Option Type (2 bytes): it contains the code that specifies the type of the current TLV record. Option types whose Most Significant Bit is equal to one are reserved for local use; therefore, there is no guarantee that the code used is unique among all capture files (generated by other applications). In case of vendor-specific extensions that have to be identified uniquely, vendors must request an Option Code whose MSB is equal to zero.

-
-<p>The file format proposed in this document should be very versatile and satisfy a wide range of applications.
-In the simplest case, it can contain a raw dump of the network data, made of a series of Simple Packet Blocks.
-In the most complex case, it can be used as a repository for heterogeneous information.
-In every case, the file remains easy to parse and an application can always skip the data it is not interested in; at the same time, different applications can share the file, and each of them can benfit of the information produced by the others.
-Two or more files can be concatenated obtaining another valid file.

-1. Objectives
-
- The problem of exchanging packet traces becomes more and more
- critical every day; unfortunately, no standard solutions exist for
- this task right now. One of the most accepted packet interchange
- formats is the one defined by libpcap, which is rather old and does
- not fit for some of the nowadays applications especially in terms of
- extensibility.
-
- This document proposes a new format for dumping packet traces. The
- following goals are being pursued:
-
- o Extensibility: aside of some common functionalities, third parties
- should be able to enrich the information embedded in the file with
- proprietary extensions, which will be ignored by tools that are
- not able to understand them.
-
- o Portability: a capture trace must contain all the information
- needed to read data independently from network, hardware and
- operating system of the machine that made the capture.
-
- o Merge/Append data: it should be possible to add data at the end of
- a given file, and the resulting file must still be readable.

-2. General File Structure
-
-2.1 General Block Structure
-
- A capture file is organized in blocks, that are appended one to
- another to form the file. All the blocks share a common format, which
- is shown in Figure 1.
-
- 0 1 2 3
- 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
- | Block Type |
- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
- | Block Total Length |
- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
- / Block Body /
- / /* variable length, aligned to 32 bits */ /
- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
- | Block Total Length |
- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
-
- Figure 1: Basic block structure.
-
- The fields have the following meaning:
-
- o Block Type (32 bits): unique value that identifies the block.
- Values whose Most Significant Bit (MSB) is equal to 1 are reserved
- for local use. They allow to save private data to the file and to
- extend the file format.
-
- o Block Total Length: total size of this block, in bytes. For
- instance, a block that does not have a body has a length of 12
- bytes.
-
- o Block Body: content of the block.
-
- o Block Total Length: total size of this block, in bytes. This field
- is duplicated for permitting backward file navigation.
-
- This structure, shared among all blocks, makes easy to process a file
- and to skip unneeded or unknown blocks. Blocks can be nested one
- inside the others (NOTE: needed?). Some of the blocks are mandatory,
- i.e. a dump file is not valid if they are not present, other are
- optional.
-
- The structure of the blocks allows to define other blocks if needed.
- A parser that does non understand them can simply ignore their
- content.

-
-2.2 Block Types
-
- The currently defined blocks are the following:
-
- 1. Section Header Block: it defines the most important
- characteristics of the capture file.
-
- 2. Interface Description Block: it defines the most important
- characteristics of the interface(s) used for capturing traffic.
-
- 3. Packet Block: it contains a single captured packet, or a portion
- of it.
-
- 4. Simple Packet Block: it contains a single captured packet, or a
- portion of it, with only a minimal set of information about it.
-
- 5. Name Resolution Block: it defines the mapping from numeric
- addresses present in the packet dump and the canonical name
- counterpart.
-
- 6. Capture Statistics Block: it defines how to store some
- statistical data (e.g. packet dropped, etc) which can be useful
- to undestand the conditions in which the capture has been made.
-
- 7. Compression Marker Block: TODO
-
- 8. Encryption Marker Block: TODO
-
- 9. Fixed Length Marker Block: TODO
-
- The following blocks instead are considered interesting but the
- authors believe that they deserve more in-depth discussion before
- being defined:
-
- 1. Further Packet Blocks
-
- 2. Directory Block
-
- 3. Traffic Statistics and Monitoring Blocks
-
- 4. Alert and Security Blocks
-
- TODO Currently standardized Block Type codes are specified in
- Appendix 1.
-
-2.3 Block Hierarchy and Precedence
-
- The file must begin with a Section Header Block. However, more than
-
-
-
-Degioanni & Risso Expires August 30, 2004 [Page 5]
-
-Internet-Draft PCAP New Generation Dump File Format March 2004
-
-
- one Section Header Block can be present on the dump, each one
- covering the data following it till the next one (or the end of
- file). A Section includes the data delimited by two Section Header
- Blocks (or by a Section Header Block and the end of the file),
- including the first Section Header Block.
-
- In case an application cannot read a Section because of different
- version number, it must skip everything until the next Section Header
- Block. Note that, in order to properly skip the blocks until the next
- section, all blocks must have the fields Type and Length at the
- beginning. This is a mandatory requirement that must be maintained in
- future versions of the block format.
-
- Figure 2 shows two valid files: the first has a typical
- configuration, with a single Section Header that covers the whole
- file. The second one contains three headers, and is normally the
- result of file concatenation. An application that understands only
- version 1.0 of the file format skips the intermediate section and
- restart processing the packets after the third Section Header.

-
- NOTE: TO BE COMPLETED with some examples of other blocks
-
-2.4 Data format
-
- Data contained in each section will always be saved according to the
- characteristics (little endian / big endian) of the dumping machine.
- This refers to all fields that are saved as numbers and that span
- over two or more bytes.
-
- The approach of having each section saved in the native format of the
- generating host is more efficient because it avoids translation of
- data when reading / writing on the host itself, which is the most
- common case when generating/processing capture dumps.

-3. Block Definition
-
- This section details the format of the body of the blocks currently
- defined.
-
-3.1 Section Header Block (mandatory)
-
- The Section Header Block is mandatory. It identifies the beginning of
- a section of the capture dump file. Its format is shown in Figure 3.
-
- 0 1 2 3
- 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

-
- Figure 3: Section Header Block format.
-
- The meaning of the fields is:
-
- o Magic: magic number, whose value is the hexadecimal number
- 0x1A2B3C4D. This number can be used to distinguish section that
- have been saved on little-endian machines from the one saved on
- big-endian machines.
-
- o Major: number of the current mayor version of the format. Current
- value is 1.
-
- o Minor: number of the current minor version of the format. Current
- value is 0.
-
- o Options: optionally, a list of options (formatted according to the
- rules defined in Section 4) can be present.
-
- Aside form the options defined in Section 4, the following options
- are valid within this block:
-
- +----------------+----------------+----------------+----------------+

- | | | | description of |
- | | | | the hardware |
- | | | | used to create |
- | | | | this section. |
- | | | | |
- | Operating | 3 | variable | An ascii |
- | System | | | string |
- | | | | containing the |
- | | | | name of the |

- | | | | application |
- | | | | used to create |
- | | | | this section. |
- +----------------+----------------+----------------+----------------+
-
- Table 1
-
- The Section Header Block does not contain data but it rather
- identifies a list of blocks (interfaces, packets) that are logically
- correlated. This block does not contain any reference to the size of
- the section it is currently delimiting, therefore the reader cannot
- skip a whole section at once. In case a section must be skipped, the
- user has to repeatedly skip all the blocks contained within it; this
- makes the parsing of the file slower but it permits to append several
- capture dumps at the same file.
-
-3.2 Interface Description Block (mandatory)
-
- The Interface Description Block is mandatory. This block is needed to
- specify the characteristics of the network interface on which the
- capture has been made. In order to properly associate the captured
- data to the corresponding interface, the Interface Description Block
- must be defined before any other block that uses it; therefore, this
- block is usually placed immediately after the Section Header Block.
-
- An Interface Description Block is valid only inside the section which
- it belongs to. The structure of a Interface Description Block is
- shown in Figure 4.

- Figure 4: Interface Description Block format.
-
- The meaning of the fields is:
-
- o Interface ID: a progressive number that identifies uniquely any
- interface inside current section. Two Interface Description Blocks
- can have the same Interface ID only if they are in different
- sections of the file. The Interface ID is referenced by the packet
- blocks.
-
- o LinkType: a value that defines the link layer type of this
- interface.
-
- o SnapLen: maximum number of bytes dumped from each packet. The
- portion of each packet that exceeds this value will not be stored
- in the file.
-
- o Options: optionally, a list of options (formatted according to the
- rules defined in Section 4) can be present.
-
- In addition to the options defined in Section 4, the following
- options are valid within this block:
-
- +----------------+----------------+----------------+----------------+
- | Name | Code | Length | Description |

-3.3 Packet Block (optional)
-
- A Packet Block is the standard container for storing the packets
- coming from the network. The Packet Block is optional because packets
- can be stored either by means of this block or the Simple Packet
- Block, which can be used to speed up dump generation. The format of a
- packet block is shown in Figure 5.

- Figure 5: Packet Block format.
-
- The Packet Block has the following fields:
-
- o Interface ID: Specifies the interface this packet comes from, and
- corresponds to the ID of one of the Interface Description Blocks
- present in this section of the file (see Figure 4).
-
- o Drops Count: a local drop counter. It specified the number of
- packets lost (by the interface and the operating system) between
- this packet and the preceding one. The value xFFFF (in
- hexadecimal) is reserved for those systems in which this
- information is not available.
-
- o Timestamp (High): the most significative part of the timestamp. in
- standard Unix format, i.e. from 1/1/1970.
-
- o Timestamp (Low): the less significative part of the timestamp. The
- way to interpret this field is specified by the 'ts_accur' option
- (see Figure 4) of the Interface Description block referenced by
- this packet. If the Interface Description block does not contain a
- 'ts_accur' option, then this field is expressed in microseconds.
-
- o Captured Len: number of bytes captured from the packet (i.e. the
-
-
-
-Degioanni & Risso Expires August 30, 2004 [Page 14]
-
-Internet-Draft PCAP New Generation Dump File Format March 2004
-
-
- length of the Packet Data field). It will be the minimum value
- among the actual Packet Length and the snapshot length (defined in
- Figure 4).
-
- o Packet Len: actual length of the packet when it was transmitted on
- the network. Can be different from Captured Len if the user wants
- only a snapshot of the packet.
-
- o Packet Data: the data coming from the network, including
- link-layer headers. The length of this field is Captured Len. The
- format of the link-layer headers depends on the LinkType field
- specified in the Interface Description Block (see Section 3.2) and
- it is specified in Appendix XXX (TODO).
-
- o Options: optionally, a list of options (formatted according to the
- rules defined in Section 4) can be present.
-
-
-3.4 Simple Packet Block (optional)
-
- The Simple Packet Block is a lightweight container for storing the
- packets coming from the network. Its presence is optional.
-
- A Simple Packet Block is similar to a Packet Block (see Section 3.3),
- but it is smaller, simpler to process and contains only a minimal set
- of information. This block is preferred to the standard Packet Block
- when performance or space occupation are critical factors, such as in
- sustained traffic dump applications. A capture file can contain both
- Packet Blocks and Simple Packet Blocks: for example, a capture tool
- could switch from Packet Blocks to Simple Packet Blocks when the
- hardware resources become critical.
-
- The Simple Packet Block does not contain the Interface ID field.
- Therefore, it must be assumed that all the Simple Packet Blocks have
- been captured on the interface previously specified in the Interface
- Description Block.
-
- Figure 6 shows the format of the Simple Packet Block.

- Figure 6: Simple Packet Block format.
-
- The Packet Block has the following fields:
-
- o Packet Len: actual length of the packet when it was transmitted on
- the network. Can be different from captured len if the packet has
- been truncated.
-
- o Packet data: the data coming from the network, including
- link-layers headers. The length of this field can be derived from
- the field Block Total Length, present in the Block Header.
-
- The Simple Packet Block does not contain the timestamp because this
- is one of the most costly operations on PCs. Additionally, there are
- applications that do not require it; e.g. an Intrusion Detection
- System is interested in packets, not in their timestamp.
-
- The Simple Packet Block is very efficient in term of disk space: a
- snapshot of length 100 bytes requires only 16 bytes of overhead,
- which corresponds to an efficiency of more than 86%.
-
-3.5 Name Resolution Block (optional)
-
- The Name Resolution Block is used to support the correlation of
- numeric addresses (present in the captured packets) and their
- corresponding canonical names and it is optional. Having the literal
- names saved in the file, this prevents the need of a name resolution
- in a delayed time, when the association between names and addresses
- can be different from the one in use at capture time. Moreover, The
- Name Resolution Block avoids the need of issuing a lot of DNS
- requests every time the trace capture is opened, and allows to have
- name resolution also when reading the capture with a machine not
- connected to the network.
-
- The format of the Name Resolution Block is shown in Figure 7.

- Figure 7: Name Resolution Block format.
-
- A Name Resolution Block is a zero-terminated list of records (in the
- TLV format), each of which contains an association between a network
- address and a name. There are three possible types of records:
-
- +----------------+----------------+----------------+----------------+
- | Name | Code | Length | Description |
- +----------------+----------------+----------------+----------------+
- | end_of_recs | 0 | 0 | End of records |

- | | | | bytes), |
- | | | | followed by |
- | | | | one or more |
- | | | | zero-terminate |
- | | | | d strings |

- Table 3
-
- After the list or Name Resolution Records, optionally, a list of
- options (formatted according to the rules defined in Section 4) can
- be present.
-
- A Name Resolution Block is normally placed at the beginning of the
- file, but no assumptions can be taken about its position. Name
- Resolution Blocks can be added in a second time by tools that process
- the file, like network analyzers.
-
- In addiction to the options defined in Section 4, the following
- options are valid within this block:
-
- +----------------+----------------+----------------+----------------+
- | Name | Code | Length | Description |
- +----------------+----------------+----------------+----------------+
- | ns_dnsname | 2 | Variable | An ascii |
- | | | | string |

-
-3.6 Interface Statistics Block (optional)
-
- The Interface Statistics Block contains the capture statistics for a
- given interface and it is optional. The statistics are referred to
- the interface defined in the current Section identified by the
- Interface ID field.

-
- The fields have the following meaning:
-
- o IfRecv: number of packets received from the interface during the
- capture. This number is reported as a 64 bits value, in which the
- most significat bits are located in the first four bytes of the
- field.
-
- o IfDrop: number of packets dropped by the interface during the
- capture due to lack of resources.
-
- o FilterAccept: number of packets accepeted by filter during current
- capture.
-
- o OSDrop: number of packets dropped by the operating system during
- the capture.
-
- o UsrDelivered: number of packets delivered to the user.
- UsrDelivered can be different from the value 'FilterAccept -
- OSDropped' because some packets could still lay in the OS buffers
- when the capture ended.

-4. Options
-
- Almost all blocks have the possibility to embed optional fields.
- Optional fields can be used to insert some information that may be
- useful when reading data, but that it is not really needed for packet
- processing. Therefore, each tool can be either read the content of
- the optional fields (if any), or skip them at once.
-
- Skipping all the optional fields at once is straightforward because
- most of the blocks have a fixed length, therefore the field Block
- Length (present in the General Block Structure, see Section 2.1) can
- be used to skip everything till the next block.
-
- Options are a list of Type - Length - Value fields, each one
- containing a single value:
-
- o Option Type (2 bytes): it contains the code that specifies the
- type of the current TLV record. Option types whose Most
- Significant Bit is equal to one are reserved for local use;
- therefore, there is no guarantee that the code used is unique
- among all capture files (generated by other applications). In case
- of vendor-specific extensions that have to be identified uniquely,
- vendors must request an Option Code whose MSB is equal to zero.
-
- o Option Length (2 bytes): it contains the length of the following
- 'Option Value' field.
-
- o Option Value (variable length): it contains the value of the given
- option. The length of this field as been specified by the Option
- Length field.
-
- Options may be repeated several times (e.g. an interface that has
- several IP addresses associated to it). The option list is terminated
- by a special code which is the 'End of Option'.
-
- The format of the optional fields is shown in Figure 9.

-5.4 Fixed Length Block (experimental)
-
- The Fixed Length Block is optional. A file can contain an arbitrary
- number of these blocks. A Fixed Length Block can be used to optimize
- the access to the file. Its format is shown in Figure 12. A Fixed
- Length Block stores records with constant size. It contains a set of
- Blocks (normally Packet Blocks or Simple Packet Blocks), of wihich it
- specifies the size. Knowing this size a priori helps to scan the file
- and to load some portions of it without truncating a block, and is
- particularly useful with cell-based networks like ATM.

-
-5.5 Directory Block (experimental)
-
- If present, this block contains the following information:
-
- o number of indexed packets (N)
-
- o table with position and length of any indexed packet (N entries)
-
- A directory block must be followed by at least N packets, otherwise
- it must be considered invalid. It can be used to efficiently load
- portions of the file to memory and to support operations on memory
- mapped files. This block can be added by tools like network analyzers
- as a consequence of file processing.
-
-5.6 Traffic Statistics and Monitoring Blocks (experimental)
-
- One or more blocks could be defined to contain network statistics or
- traffic monitoring information. They could be use to store data
- collected from RMON or Netflow probes, or from other network
- monitoring tools.
-
-5.7 Event/Security Block (experimental)
-
- This block could be used to store events. Events could contain
- generic information (for example network load over 50%, server
- down...) or security alerts. An event could be:

- o skipped, if the application doesn't know how to do with it
-
- o processed independently by the packets. In other words, the
- applications skips the packets and processes only the alerts
-
- o processed in relation to packets: for example, a security tool
- could load only the packets of the file that are near a security
- alert; a monitorg tool could skip the packets captured while the
- server was down.

-6. Conclusions
-
- The file format proposed in this document should be very versatile
- and satisfy a wide range of applications. In the simplest case, it
- can contain a raw dump of the network data, made of a series of
- Simple Packet Blocks. In the most complex case, it can be used as a
- repository for heterogeneous information. In every case, the file
- remains easy to parse and an application can always skip the data it
- is not interested in; at the same time, different applications can
- share the file, and each of them can benfit of the information
- produced by the others. Two or more files can be concatenated
- obtaining another valid file.

- <abstract>
-<t>This document describes a format to dump captured packets on a file. This format is extensible and it is currently proposed for implementation in the libpcap/WinPcap packet capture library.</t>
- </abstract>

-<section title="Objectives">
-<t>The problem of exchanging packet traces becomes more and more critical every day; unfortunately, no standard solutions exist for this task right now. One of the most accepted packet interchange formats is the one defined by libpcap, which is rather old and does not fit for some of the nowadays applications especially in terms of extensibility.</t>
-<t>This document proposes a new format for dumping packet traces. The following goals are being pursued:</t>
-<list style="symbols">
-<t>Extensibility: aside of some common functionalities, third parties should be able to enrich the information embedded in the file with proprietary extensions, which will be ignored by tools that are not able to understand them.</t>
-<t>Portability: a capture trace must contain all the information needed to read data independently from network, hardware and operating system of the machine that made the capture.</t>
-<t>Merge/Append data: it should be possible to add data at the end of a given file, and the resulting file must still be readable.</t>

-<section anchor="sectionblock" title="General Block Structure">
-<t>A capture file is organized in blocks, that are appended one to another to form the file. All the blocks share a common format, which is shown in <xref target="formatblock"/>.</t>

-<t>The fields have the following meaning:</t>
-
-<list style="symbols">
-<t>Block Type (32 bits): unique value that identifies the block. Values whose Most Significant Bit (MSB) is equal to 1 are reserved for local use. They allow to save private data to the file and to extend the file format.</t>
-<t>Block Total Length: total size of this block, in bytes. For instance, a block that does not have a body has a length of 12 bytes.</t>
-<t>Block Body: content of the block.</t>
-<t>Block Total Length: total size of this block, in bytes. This field is duplicated for permitting backward file navigation.</t>
-</list>
-
-<t>This structure, shared among all blocks, makes easy to process a file and to skip unneeded or unknown blocks. Blocks can be nested one inside the others (NOTE: needed?). Some of the blocks are mandatory, i.e. a dump file is not valid if they are not present, other are optional.</t>
-<t>The structure of the blocks allows to define other blocks if needed. A parser that does non understand them can simply ignore their content.</t>
-</section>
-
-<section title="Block Types">
-<t>The currently defined blocks are the following:</t>
-<list style="numbers">
-<t>Section Header Block: it defines the most important characteristics of the capture file.</t>
-<t>Interface Description Block: it defines the most important characteristics of the interface(s) used for capturing traffic.</t>
-<t>Packet Block: it contains a single captured packet, or a portion of it.</t>
-<t>Simple Packet Block: it contains a single captured packet, or a portion of it, with only a minimal set of information about it.</t>
-<t>Name Resolution Block: it defines the mapping from numeric addresses present in the packet dump and the canonical name counterpart.</t>
-<t>Capture Statistics Block: it defines how to store some statistical data (e.g. packet dropped, etc) which can be useful to undestand the conditions in which the capture has been made.</t>
-<t>Compression Marker Block: TODO</t>
-<t>Encryption Marker Block: TODO</t>
-<t>Fixed Length Marker Block: TODO</t>

-<list style="numbers">
-<t>Further Packet Blocks</t>
-<t>Directory Block</t>
-<t>Traffic Statistics and Monitoring Blocks</t>
-<t>Alert and Security Blocks</t>
-</list>
-
-<t>TODO Currently standardized Block Type codes are specified in Appendix 1.</t>
-
-</section>
-
-<section title="Block Hierarchy and Precedence">
-<t>The file must begin with a Section Header Block. However, more than one Section Header Block can be present on the dump, each one covering the data following it till the next one (or the end of file). A Section includes the data delimited by two Section Header Blocks (or by a Section Header Block and the end of the file), including the first Section Header Block.</t>
-<t>In case an application cannot read a Section because of different version number, it must skip everything until the next Section Header Block. Note that, in order to properly skip the blocks until the next section, all blocks must have the fields Type and Length at the beginning. This is a mandatory requirement that must be maintained in future versions of the block format.</t>
-<t><xref target="fssample-SHB"/> shows two valid files: the first has a typical configuration, with a single Section Header that covers the whole file. The second one contains three headers, and is normally the result of file concatenation. An application that understands only version 1.0 of the file format skips the intermediate section and restart processing the packets after the third Section Header.</t>

-<t>Data contained in each section will always be saved according to the characteristics (little endian / big endian) of the dumping machine. This refers to all fields that are saved as numbers and that span over two or more bytes.</t>
-<t>The approach of having each section saved in the native format of the generating host is more efficient because it avoids translation of data when reading / writing on the host itself, which is the most common case when generating/processing capture dumps.</t>

-
-<t>The Section Header Block does not contain data but it rather identifies a list of blocks (interfaces, packets) that are logically correlated. This block does not contain any reference to the size of the section it is currently delimiting, therefore the reader cannot skip a whole section at once. In case a section must be skipped, the user has to repeatedly skip all the blocks contained within it; this makes the parsing of the file slower but it permits to append several capture dumps at the same file.</t>

-
-<section anchor="sectionidb" title="Interface Description Block (mandatory)">
-<t>The Interface Description Block is mandatory. This block is needed to specify the characteristics of the network interface on which the capture has been made. In order to properly associate the captured data to the corresponding interface, the Interface Description Block must be defined before any other block that uses it; therefore, this block is usually placed immediately after the Section Header Block.</t>
-

-<t>The Packet Block has the following fields:</t>
-
-<list style="symbols">
-<t>Interface ID: Specifies the interface this packet comes from, and corresponds to the ID of one of the Interface Description Blocks present in this section of the file (see <xref target="formatidb"/>).</t>
-<t>Drops Count: a local drop counter. It specified the number of packets lost (by the interface and the operating system) between this packet and the preceding one. The value xFFFF (in hexadecimal) is reserved for those systems in which this information is not available.</t>
-<t>Timestamp (High): the most significative part of the timestamp. in standard Unix format, i.e. from 1/1/1970.</t>
-<t>Timestamp (Low): the less significative part of the timestamp. The way to interpret this field is specified by the 'ts_accur' option (see <xref target="formatidb"/>) of the Interface Description block referenced by this packet. If the Interface Description block does not contain a 'ts_accur' option, then this field is expressed in microseconds.</t>
-<t>Captured Len: number of bytes captured from the packet (i.e. the length of the Packet Data field). It will be the minimum value among the actual Packet Length and the snapshot length (defined in <xref target="formatidb"/>).</t>
-<t>Packet Len: actual length of the packet when it was transmitted on the network. Can be different from Captured Len if the user wants only a snapshot of the packet.</t>
-<t>Packet Data: the data coming from the network, including link-layer headers. The length of this field is Captured Len. The format of the link-layer headers depends on the LinkType field specified in the Interface Description Block (see <xref target="sectionidb"/>) and it is specified in Appendix XXX (TODO).</t>
-<t>Options: optionally, a list of options (formatted according to the rules defined in <xref target="sectionopt"/>) can be present.</t>

-<section title="Simple Packet Block (optional)">
-<t>The Simple Packet Block is a lightweight container for storing the packets coming from the network. Its presence is optional.</t>
-<t>A Simple Packet Block is similar to a Packet Block (see <xref target="sectionpb"/>), but it is smaller, simpler to process and contains only a minimal set of information. This block is preferred to the standard Packet Block when performance or space occupation are critical factors, such as in sustained traffic dump applications. A capture file can contain both Packet Blocks and Simple Packet Blocks: for example, a capture tool could switch from Packet Blocks to Simple Packet Blocks when the hardware resources become critical.</t>
-<t>The Simple Packet Block does not contain the Interface ID field. Therefore, it must be assumed that all the Simple Packet Blocks have been captured on the interface previously specified in the Interface Description Block.</t>

-<t>Packet Len: actual length of the packet when it was transmitted on the network. Can be different from captured len if the packet has been truncated.</t>
-<t>Packet data: the data coming from the network, including link-layers headers. The length of this field can be derived from the field Block Total Length, present in the Block Header.</t>
-</list>
-
-<t>The Simple Packet Block does not contain the timestamp because this is one of the most costly operations on PCs. Additionally, there are applications that do not require it; e.g. an Intrusion Detection System is interested in packets, not in their timestamp.</t>

-<section title="Name Resolution Block (optional)">
-<t>The Name Resolution Block is used to support the correlation of numeric addresses (present in the captured packets) and their corresponding canonical names and it is optional. Having the literal names saved in the file, this prevents the need of a name resolution in a delayed time, when the association between names and addresses can be different from the one in use at capture time. Moreover, The Name Resolution Block avoids the need of issuing a lot of DNS requests every time the trace capture is opened, and allows to have name resolution also when reading the capture with a machine not connected to the network.</t>

Therefore, each tool can be either read the content of the optional fields (if any), or skip them at once.</t>
-<t>Skipping all the optional fields at once is straightforward because most of the blocks have a fixed length, therefore the field Block Length (present in the General Block Structure, see <xref target="sectionblock"/>) can be used to skip everything till the next block.</t>

Option types whose Most Significant Bit is equal to one are reserved for local use; therefore, there is no guarantee that the code used is unique among all capture files (generated by other applications). In case of vendor-specific extensions that have to be identified uniquely, vendors must request an Option Code whose MSB is equal to zero.</t>

-In the most complex case, it can be used as a repository for heterogeneous information.
-In every case, the file remains easy to parse and an application can always skip the data it is not interested in; at the same time, different applications can share the file, and each of them can benfit of the information produced by the others.
-Two or more files can be concatenated obtaining another valid file.</t>

-Libpcap provides a portable framework for low-level network
-monitoring. Libpcap can provide network statistics collection,

-authors created this system-independent API to ease in porting and to
-alleviate the need for several system-dependent packet capture modules

+By default, when performing a live capture or reading from a savefile,
+time stamps are supplied as seconds since January 1, 1970, 00:00:00 UTC,
+and microseconds since that seconds value, even if higher-resolution
+time stamps are available from the capture device or in the savefile.
+If, when reading a savefile, the time stamps in the file have a higher
+resolution than one microsecond, the additional digits of resolution are
+discarded.
+.LP
+The
+.BR pcap_set_tstamp_precision (3PCAP)
+routine can be used after a
+.B pcap_create()
+call and after a
+.B pcap_activate()
+call to specify the resolution of the time stamps to get for the device.
+If the hardware or software cannot supply a higher-resolution time
+stamp, the
+.B pcap_set_tstamp_precision()
+call will fail, and the time stamps supplied after the
+.B pcap_activate()
+call will have microsecond resolution.
+.LP
+When opening a savefile, the
+.BR pcap_open_offline_with_tstamp_precision (3PCAP)
+and
+.BR pcap_fopen_offline_with_tstamp_precision (3PCAP)
+routines can be used to specify the resolution of time stamps to be read
+from the file; if the time stamps in the file have a lower resolution,
+the fraction-of-a-second portion of the time stamps will be scaled to
+the specified resolution.
+.LP
+The
+.BR pcap_get_tstamp_precision (3PCAP)
+routine returns the resolution of time stamps that will be supplied;
+when capturing packets, this does not reflect the actual precision of
+the time stamp supplied by the hardware or operating system and, when
+reading a savefile, this does not indicate the actual precision of time
+stamps in the file.

+ * used DLT_USER2, which causes problems for everything except for
+ * their version of tcpdump.
+ *
+ * So I'll just give them one; hopefully this will show up in a
+ * libpcap release in time for them to get this into 10.10 Big Sur
+ * or whatever Mavericks' successor is called. LINKTYPE_PKTAP
+ * will be 258 *even on OS X*; that is *intentional*, so that
+ * PKTAP files look the same on *all* OSes (different OSes can have
+ * different numerical values for a given DLT_, but *MUST NOT* have
+ * different values for what goes in a file, as files can be moved
+ * between OSes!).
+ *
+ * When capturing, on a system with a Darwin-based OS, on a device
+ * that returns 149 (DLT_USER2 and Apple's DLT_PKTAP) with this
+ * version of libpcap, the DLT_ value for the pcap_t will be DLT_PKTAP,
+ * and that will continue to be DLT_USER2 on Darwin-based OSes. That way,
+ * binary compatibility with Mavericks is preserved for programs using
+ * this version of libpcap. This does mean that if you were using
+ * DLT_USER2 for some capture device on OS X, you can't do so with
+ * this version of libpcap, just as you can't with Apple's libpcap -
+ * on OS X, they define DLT_PKTAP to be DLT_USER2, so programs won't
+ * be able to distinguish between PKTAP and whatever you were using
+ * DLT_USER2 for.
+ *
+ * If the program saves the capture to a file using this version of
+ * libpcap's pcap_dump code, the LINKTYPE_ value in the file will be
+ * LINKTYPE_PKTAP, which will be 258, even on Darwin-based OSes.
+ * That way, the file will *not* be a DLT_USER2 file. That means
+ * that the latest version of tcpdump, when built with this version
+ * of libpcap, and sufficiently recent versions of Wireshark will
+ * be able to read those files and interpret them correctly; however,
+ * Apple's version of tcpdump in OS X 10.9 won't be able to handle
+ * them. (Hopefully, Apple will pick up this version of libpcap,
+ * and the corresponding version of tcpdump, so that tcpdump will
+ * be able to handle the old LINKTYPE_USER2 captures *and* the new
+ * LINKTYPE_PKTAP captures.)
