Hi Domingo,

Does this capture filter help you:
-f "(len<=100) && (udp || tcp[13:1] == 2 || tcp[13:1] == 16)"

$ tshark -i 2 -f "(len<=100) && (udp || tcp[13:1] == 2 || tcp[13:1] == 16)"
-w test2.pcap

Best regards
Joan

Hello Guys,

I use Tshark for network monitoring and sniffing of malicious traffic at

work and I am trying to figure out how I can get Tshark to stop showing

packets that are TCP [TCP segment of a reassembled PDU] and HTTP Continuation or non-HTTP traffic.

I only need this in Tshark and not Wireshark. I use tshark Live to view

any incoming attacks (SYN Floods, ACK, Flood, UDP, Floods) and when I do

see an attack sometimes my out put is flooded with [TCP segment of a reassembled PDU] and HTTP Continuation or non-HTTP traffic responses.

Sincerely,
