This example demonstrates use of the iperf library in KasperskyOS.
In this example, the Server program uses the iperf library.
By default, the example uses network software emulation (SLIRP) in QEMU. If you configured TAP interfaces for QEMU, you need to change the network settings for starting QEMU (QEMU_NET_FLAGS variable) in the einit/CMakeLists.txt file to make sure that the example works correctly (for more details, see the comments in the file).
The example does not use DHCP, therefore the IP address of the network interface must be manually indicated in the code of the Server program (server/src/main.cpp). SLIRP uses the default values.
The iperf library in the example is used in server mode. To connect to this server, install the iperf3 program on the host machine and run it by using the iperf3 -c localhost command. If you configured TAP interfaces, indicate the current IP address instead of localhost.
The first startup of the example may take a long time because the iperf client uses /dev/urandom to fill packets with random data. To avoid this, run the iperf client with the --repeating-payload parameter.
The CMake system, which is included with KasperskyOS Community Edition, is used to build and run the example.
