Packet generation and replaying tools
During downtime, especially in a case when any network device goes down in a network infrastructure, network administrators need to understand the root cause of a device’s failure. So, to understand the root cause, the administrators send crafted packets into the network (known as packet replays) to understand the behavior of the devices and failure points.
For example, during some implementations, a server lost a connection with the whole network. Therefore, administrators send Traceroute and ICMP packets to understand the failure. So, the last capture packet was dropped at some firewall in between, which means that during implementation, the network team forgot to open the connection at the firewall.
Hence, packet generation and replaying packets are techniques via which the network team creates and sends the packets, such as TCP, ICMP, UDP, and ARP, in a raw format to the targeted device and capture the response, to learn about...
