A small tool that I quickly put together because I couldn't find a simple way to generate a small burst of GET requests. It generates strings to be used with the GET request by appending a random 6 hexadecimal number on the OUI.
It is split into two versions: one which sends requests one after the other while waiting for a response before sending another request and a version which sends all the requests almost at once, without waiting for a response.
./tftp_stress_serial -address=10.0.0.1 -port=69 -oui=00aabb -num=200
You can also use the -help flag to see the explanations for each flag and their default values.
