Hello sir,
I have a problem in display filters. Whenever I apply a display filter
for the packets say (frame.number >= 12 && frame.number <-=100) I will
get the filtered packets on the screen but with different packet info.
The value of the packet info will be different.
1. I want to know whenever I apply display filters etheeal gets bytes from
the memory or reads from the captured file.Where does it get the
packet_info? ie where will be the value of the packet_info stored so that
ethereal get its value when filtering is applied.
2. Please tell me in which part of the code I can check the value of the
packet_info column when filtering is applied.
Regards
Harsha
