WAND is a research group at the University of Waikato Computer Science Department. The group is involved with a range of computer networks projects mostly focused around network measurement. The group has a strong international reputation and has close links, including collaborative research, with several other network measurement groups. These include CAIDA, Sprint and Agilent.

Our work includes collection of very long trace sets, network analysis and software to support this, active measurement systems, wireless networks for rural communities, rapid deployment networks, OS code based network simulation and network visualisation. Spinoffs from our work include Endace and Rural Link.

Libtrace 4.0.2 has been released today.

This release adds two new input formats: pcapng and nDAG.

This release also includes the following bug fixes:
* Fixed bad IPv6 fragment offset calculation that would randomly cause IPv6 packets to be incorrectly parsed.
* Fixed bug where SIGINT would cause parallel programs to assert fail.
* Fixed compilation issues caused by inconsistent BPF presence checks.
* Fixed errors in IPv6 and SCTP libpacketdump decoders.
* Fixed bug where a short cryptopan key would cause traceanon to assert fail.
* Fixed compilation error when building traceanon against new versions of libssl.
* Fixed bug where DPDK would not be detected if it had been built as a shared library.
* Fixed bug where the wrong parallel read function would be used by libtrace.

The full list of changes in this release can be found in the libtrace ChangeLog.

You can download the new version of libtrace from the libtrace website.

Libprotoident 2.0.12 has been released.

This release is mostly a protocol database update. We've added 26 new protocols and updated a further 33 others since the last release.

We've also added a new category for IP Camera protocols. Some already existing protocols have been moved into this category to better reflect their purpose.

The full list of updated protocols can be found in the libprotoident ChangeLog.

Libprotoident 2.0.11 has been released.

Firstly, this release updates the existing tools to be compatible with both libflowmanager 3 and parallel libtrace. This means that the tools can now take advantage of any parallelism in the traffic source, e.g. streams on a DAG card or a DPDK-capable NIC.

Secondly, we've added 61 new application protocols to our set of detectable protocols, bringing the total supported number of applications to 407. A further 25 existing protocols have been updated to better match new observed traffic patterns.

Finally, there have been a couple of minor bug fixes as well.

Note that this release will require both libflowmanager 3 and libtrace 4, which means that you will likely have to upgrade these libraries prior to installing libprotoident 2.0.11. If this is problematic for you but you still want the new application protocol rules, you can use the '--with-tools=no' option when running ./configure to prevent the tools (which are the reason for the upgraded dependencies) from being built.

The full list of updated protocols can be found in the libprotoident ChangeLog.

Libflowmanager 3.0.0 has been released today.

The libflowmanager API has been re-written to be thread-safe (and therefore compatible with parallel libtrace), hence the major version number change.

The old libflowmanager API has been removed entirely; there is no backwards compatibility with previous versions of libflowmanager. If you choose to install libflowmanager 3 then you will need to update your existing code to use the new API. This should not be too onerous in most cases, as most of the old global API functions have simply been replaced with method calls to a FlowManager class instance. The README and example programs demonstrate and explain the new API in detail.

Note that much of our other software that relies on libflowmanager, such as the libprotoident tools and lpicollector, have NOT yet been officially released with libflowmanager 3 support. If you are currently using any of this software, you should continue to use libflowmanager 2.0.5 until we are able to test and release new libflowmanager 3 compatible versions.

You can download both libflowmanager 3 and libflowmanager 2.0.5 from our website.

Libtrace 4.0.1 has been released today.

This release addresses a number of bugs in the new parallel API and updates our DPDK support to be compatible with the latest stable DPDK release (16.07.2).

This release includes the following changes / fixes:
* Fixed bug where libtrace's built-in hasher would always sent packets to the same thread.
* Fixed terrible performance for tracertstats when reading from live formats.
* Fixed bug where trace_pstop() would fail for ring: and int: on older kernels.
* Added support for IPv6 within PPP.
* Added support for PPTP when parsing GRE headers.
* Added API function trace_clear_statistics().
* Fixed race conditions when using parallel API to read from a file.
* Generally improved performance for live formats when using the parallel API by removing an unnecessary mutex.
* Fixed bug where the ordered combiner seemed to be returning packets out-of-order.

The full list of changes in this release can be found in the libtrace ChangeLog.

You can download the new version of libtrace from the libtrace website.

Libprotoident 2.0.10 has been released.

This release includes rules to match new traffic patterns for many of the protocols that we introduced in the 2.0.9 release. We've also added two new protocols: BACnet and Maxicloud.

This release also no longer treats TCP keepalive packets as payload-bearing.

The full list of updated protocols can be found in the new libprotoident ChangeLog.
