![]() Filter by IP address: ip.addr x.x.x.x, where x.x.x.x is the IP address you want to filter 2. Here are some common types of filters that you can use in Wireshark: 1. After this, browse to any web address and then return to Wireshark. Filters can be based on various criteria, such as IP addresses, protocols, port numbers, and packet contents. Select a particular Ethernet adapter and click start. We shall be following the below steps: In the menu bar, Capture Interfaces. Relationship between the port numbers in the two packets : The source port for packet 15 is the destination port for packet 17 and it can be applied in the opposite. After we start Wireshark, we can analyze DNS queries easily. Packet number of the second of these two UDP segments in the trace file : 17Ĭ. Packet number of the first of these two UDP segments in the trace file : 15ī. Ukuran terbesar yang mungkin dari source port number adalah (2^16 – 1) = 65535. Maksimum nilai pada UDP payload adalah (2^16 – 1) bytes plus header bytes sehingga 65535 bytes – 8 bytes = 65527 bytes. Length UDP payload pada packet ini adalah 292 bytes - 8 bytes = 284 bytes. Explicit length value dibutuhkan karena ukuran field data dapat berbeda dari sebuah UDP segment dengan UDP segment setelahnya. Length field memiliki value dari header + data. Masing-masing dari 4 fields UDP header memiliki length 2 bytes. ![]() ![]() UDP header memiliki panjang tetap yaitu 8 bytes. 4 fields in UDP header : source port, destination port, length, checksum No 2 SSDP (Simple Service Discovery Protocol)Ĭ. Receiver typically acknowledge 1448 bytes Wireshark UDP No 1ī. No, because the packet was sent by MIME multipart No 7Īns : 4 * (Payload + Header) = 4 * (1448 + 32) = 4 * 1480 = 5920 byte No 10 From sequence number segmen SYN before, that is 4236649187, plus by one No 5Ĭ. Sequence number (raw) TCP SYNACK : 1068969752ĭ. Yes, because SACK allowed in SYN segment No 4Ī.
