This is a new version of our HTTP Profile for Wireshark. Wireshark defaults to this header reassembly process being ON. I have added a different version of this profile with this setting turned off – FYI.

This is a new version of our HTTP Profile for Wireshark. Wireshark defaults to a header reassembly process. I have added this version of this profile with this setting turned off. Everything else is the same between the two profiles.

For those of you who love Wireshark and are supporting IPv6, we would like to offer an alternative to our default profile for IPv6. This one I call my IPv6 Super Profile. I created this based on modifying the Default IPv6 profile for a client that they called “super”. Think of it as a variation.

Thanks for looking – this is our ULTIMATE pcap file. Sure, there are others out there, but they all seem to be missing something. Grab this GZIP file, no need to unzip it as Wireshark will open it directly, and use this for learning, testing, development of profiles with Wireshark or whatever tool you like,

TCP Delta Time refers to the time difference between consecutive Transmission Control Protocol (TCP) packets in a data transmission. It is an important metric when analyzing network performance for several reasons: 1. Network Latency and Performance High Delta Times: When the delta time between TCP packets is high, it may indicate network latency, congestion, or

TCP Sequence analysis is critical in network troubleshooting because it provides insights into the flow and order of data being transmitted over a network. Here’s why it plays such a crucial role in diagnosing network issues: 1. Ensuring Data Integrity and Order TCP Sequence Numbers: TCP assigns sequence numbers to each byte of data sent

This LTE profile for Wireshark is contributed by Brent Crier | Network Engineer. Thanks Brent!
This is a Wireshark profile that helps analyze IEC 60870 packets. IEC 60870 part 5 is one of the IEC 60870 set of standards which define systems used for telecontrol (supervisory control and data acquisition) in electrical engineering and power system automation applications. Part 5 provides a communication profile for sending basic telecontrol messages between

TCP Selective Acknowledgment (SACK) analysis is crucial for troubleshooting network performance and reliability because it provides enhanced mechanisms for handling packet loss, retransmissions, and improving overall efficiency of TCP communications. Here’s why TCP SACK analysis is important in network troubleshooting: 1. Handling Packet Loss More Efficiently Traditional Acknowledgment (ACK) vs. SACK: In traditional TCP, when

NVMe (Non-Volatile Memory Express) is a high-performance storage protocol designed specifically for modern non-volatile memory, such as SSDs (Solid-State Drives), to reduce latency and improve the speed of data transfers. Unlike older storage protocols like SATA or SAS, which were originally developed for slower spinning disks, NVMe leverages the parallelism of PCIe (Peripheral Component Interconnect

NVMe over Fabrics (NVMe-OF) is an extension of the NVMe protocol designed to enable high-performance access to NVMe-based storage devices across a network fabric, such as Ethernet, Fibre Channel, or InfiniBand, rather than being limited to a local PCIe connection. NVMe-OF allows the benefits of NVMe, including low latency and high throughput, to be extended

iSCSI (Internet Small Computer Systems Interface) is a protocol that allows for the transport of block-level data over IP networks, enabling devices such as servers to access storage over a network as if it were locally attached. iSCSI encapsulates SCSI commands into TCP/IP packets, allowing storage devices to communicate with servers over standard Ethernet networks

RDMA over Converged Ethernet (RoCE) is a network protocol that enables Remote Direct Memory Access (RDMA) over Ethernet networks. RDMA is a technology that allows data to be transferred directly from the memory of one computer to another without involving the operating system or CPU, which reduces latency and increases throughput. RoCE enables this capability

This is a Wireshark profile specifically to help with GRE Tunnel Analysis. Troubleshooting Generic Routing Encapsulation (GRE) tunnels is important because GRE tunnels play a critical role in various networking environments, particularly in enterprise and service provider networks. GRE tunnels are used for encapsulating packets, enabling secure communication between networks, and supporting multiple routing protocols.
