Now, I need to calculate the number of IP packets that have IP header error (bad check sum)errors, using wireshark. Can any tell me the steps to do this.
How about just using a display filter of "ip.checksum_bad==1"? The number of packets matching the filter will be displayed and the count of them is indicated in the status bar. Alternatively, tshark could be used instead, e.g., tshark -r file.pcap -R "ip.checksum_bad == 1" | wc -l ___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-users Unsubscribe: https://wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org?subject=unsubscribe
