[1] This is carried out either by the originator or by an adversary who intercepts the data and re-transmits it, possibly as part of a spoofing attack by IP packet substitution. 49. To replay packets, one at a time while decoding it (useful for debugging purposes): # tcpreplay --oneatatime --verbose --intf1=eth0 sample. For example, if we capture packets The GapReplay is proposed, a packet replayer that can remain identical with the original nanosecond-precision pcap trace in packet contents and achieve high accuracy in timestamps, much better than the state-of-the-art such as MoonGen and tcpreplay. Use packet buffer: Input packet data (both header and payload) or just copy from other places and paste it. we are usıng fortigate 600d . is there any way to send this dump into one of the interfaces? I thought tcpdump would be able to do this on its own (unfortunately it isn't). This operation is carried out by a malicious node who intercepts tures, packet classification algorithms, queue management algorithms, scheduling algorithms, and buffer provisioning in a very realistic environment. You could try Edit -> Time Shift on the reversed file, and then set the time for packet 1 to some time of your choosing, followed by setting the time for the last packet to another time of your choosing, and let Wireshark extrapolate the timestamps for all other packets in between.

The reasons can be multiple including verifying operation of supplied detections against known traffic, gathering evidence of an attack where no detections were available, or using PCAP samples to write broader detections. In this way when you replay the packets it should go in the same order. Improve this answer. Community Bot. when we check the packet , source and destination interface is unknown and there is no packet going through. Simulating realistic traffic in an SDN testbed can be difficult. A replay attack (also known as a repeat attack or playback attack) is a form of network [1] attack in which valid data transmission is maliciously or fraudulently repeated or delayed.
