Thank you for the vid. But if someone ever comes here, please tell me how to change time display format for this new TCP Delay column? From 0.0XXYYZZ to XX(ms), or something like that?
Laura, -how might you do a range?- (Edit: Never mind, found it.) I'm used to ports ranges with two dots but not sure about reponses. I guess I can do *sip.Status-Code > 199 && sip.Status-Code < 300* for 2XX but know of one line?
omg I thought I was deep into wireshark as it was but I literally just now found out you can right click the display filter to find a builder! I now have *any sip.Status-Code in {200..299}*
Okay well now I must admit this was to colorize packets. I realized it would be more useful to color specific types of responses to match the request method. Like both OPTIONS and 200 OK (OPTIONS) light yellow. I realized it's not good to go blanket all 4xx red for instance because 401 is so regular it shouldn't be bleeding eye red. Okay now I'm on the right path, thanks!
Hi Laura...thanks for the video! Is that tracefile still available? I'm a newbie to all of this so please excuse my ignorance and make it as simple as possible to find the tracefile please...thank you..
thanks Laura for your help...so...am I right in thinking a trace file is just a pcap file stored on my computer then when I want to open it i use wireshark or credentials as when I open any stored pcapng files in tools/credentials there is nothing showing up!? although it does open the file there is nothing in that file!? @@LauraChappellLab
your already have connection/physical access to the network to be getting any packet info? the same would be true for trying to packet capture a wifi connection, if no group key update is sent you wont ever be able to capture packets and if your really paranoid you could just create a point to point wifi link and then have a vpn server on one end and a client on the other so that all traffic is encrypted the moment it enters and is decrypted on the other side so beyond secure for better words
