Debian stretch's init script for isc-dhcp-server uses the INTERFACESv4|6 variables to decide whether to start the v4 and/or v6 DHCP server. If they are not empty, the daemon is started for the respective version, however, if both are empty (the default), to listen on all interfaces, the daemon is started for both versions. The latter would require a subnet config for IPv6 as the daemon otherwise exits, letting the init script fail, while keeping the successfully started v4 version running, which, in turn, can't be stopped anymore with the init script because it thinks the daemon is not running. So it's not possible with this init script to start DHCPv4 on all interfaces without having to configure and run DHCPv6 also.

strongSwan Integration Tests

1. Building the testing environment
2. Starting up the testing environment
3. Running the automated tests
4. Manual testing
1. Building the testing environment
--------------------------------
The testing environment can be built with the "make-testing" script after
adjusting the variables in the testing.conf file. By default everything is
built when executing the script. Setting any of the ENABLE_BUILD_* variables
in the configuration file to "no" will not build those parts.
2. Starting up the testing environment
-----------------------------------
When the strongSwan testing environment has been put into place by running
the "make-testing" script you are ready to start up the KVM instances by
executing the "start-testing" script.
3. Running the automated tests
---------------------------
The script
./do-tests <testnames>
runs the automated tests. If the <testnames> argument is omitted all tests
are executed, otherwise only the tests listed will be run as shown in the
example below:
./do-tests ikev2/net2net-psk ikev2/net2net-cert
Each test is divided into the following phases:
* Load the test-specific guest configuration if any is provided.
* Next the "pretest.dat" script found in each test directory is executed.
Among other commands, strongSwan is started on the IPsec hosts.
* The "evaltest.dat" script evaluates if the test has been successful.
* The "posttest.dat" script terminates the test e.g. by stopping
strongSwan on the IPsec hosts. It is also responsible to cleaning up
things (e.g. firewall rules) set up in "pretest.dat".
* Restore the default configuration on every host (new files have to be
deleted manually in "posttest.dat").
The test results and configuration files for all tests are stored in a
folder labeled with the current date and time in the $TESTRESULTSDIR directory.
The same results are also automatically transferred to the Apache server
running on guest "winnetou" and can be accessed via the URL
http://192.168.0.150/testresults/
4. Manual testing
--------------
Instead of running tests automatically with "do-tests" it is possible to
preload a test scenario with the script:
scripts/load-testconfig <testname>
Individual configuration files can be changed and any command can be executed by
logging into a guest host directly (via SSH or a console window). No password
is required to login as root. The sources for every software built during
"make-testing" are mounted at /root/shared/, which allows you to change and
recompile these components.
After you have finished testing, the default configuration can be restored
with the following command (newly created files have to be deleted manually)
scripts/restore-defaults
