Eureka Effects - Things that I learned today Add idea

Filter for individual file name (case sensitive)</br> <strong>smb2.filename contains "manifest.xml"</strong>

Wireshark mesuring response time of protocols like HTTP and SMB

The importance of the TCP dissector to reassemble TCP Streams

Filter for SMB2 using regex</br> <strong>smb2.tree matches "[sS]pace[oO]ps"</strong>

Locate broadcast for each new passenger:</br><strong>udp.port == 33333</strong>

Filter for exact name of SMB2 Tree (case blind)</br> <strong>smb2.tree contains "SpaceOps"</strong>

tcp.stream == 18 and (smb or smb2)

alternate to smb.cmd Negotiate Protocol (smb offest byte 4 = 0x72) smb[4]==0x72

Very low throughput between client and server

slow database interaction

Query timing out

Not aggregating Passenger lookups- executing only one lookup at a time

small windowsize
