Which Software for the Job?

Capture packets, test the ISP link, time a WAN link, find open ports, reach a switch, check Wi-Fi. Pick the software.

⚑ Complete this interactive to capture a CTF flag worth 5 points.

About this interactive

The lesson's software: - **Protocol analyzer** (Wireshark): captures traffic, often from a mirrored port, and lets you read each packet. - **Speed test** (Google's, Ookla's speedtest.net): download, upload and latency to a test server on the internet; is the ISP delivering what you pay for? - **iPerf:** a client on one network and a server on another stream test traffic between them to measure throughput. - **Port scanner:** finds which ports are open on a machine, and which should not be. - **Terminal emulator:** a command session on a device, to read interfaces, debug output and configuration. - **Wi-Fi analyzer:** the access points you can hear, their MAC addresses, channels and widths. The lesson also lists a TFTP server, which stores logs and configuration files; it holds files rather than testing anything, so it is not a bin.
