▲Displays all TCP packets that contain the word ‘traffic’. Excellent when searching on a specific string or user ID:
|Sets a filter for the HEX values of 0x33 0x27 0x58 at any offset || udp contains 33:27:58 ▼

|Displays all retransmissions in the trace.
▲Masks out arp, icmp, dns, or whatever other protocols may be background noise. Allowing you to focus on the traffic of interest:

▲ ip.flags.mf == 1 or ip.frag_offset > 0
▲ICMP Fragmentation needed packets:
▲ ip[0,9,20:2]==4501:0304||ip[6:2]&3fff
▲ tcp.flags&7 or (tcp.seq==1 and tcp.ack==1 and !tcp.window_size_scalefactor==-1 and tcp.len==0)
