This TCP testsuite focuses on testing FreeBSD's TCP stack.

It it based on the packetdrill testtool. The original version is available from Google's repository. However, this version does not really run on FreeBSD. An extended version is available from NPLab's respository overcoming this limitation and adding support for SCTP and UDPLite.

You can get the testsuite by running

git clone https://github.com/freebsd-net/tcp-testsuite.git

To run all test scripts, execute

sudo tcp-testsuite/run-all-tests

which runs the tcsh script tcp-testsuite/run-all-tests with root priviledges.
