This means that once the driver is turned on, the absolute time is once got from the system clock, but after this, system performance counters will be used for updating the time. With the default mode 0, the absolute accuracy is “a one-shot accuracy”, since system performance counters are used for providing high timestamp resolution, but the absolute time is not synchronized. Npcap and WinPcap support several timestamp modes. At least, with tests carried out, we haven’t yet been successful in modifying the timestamp mode.ĭownload Win10Pcap 4. One technical downside is that it is not confirmed whether the different timestamp modes are supported or not in Win10Pcap. In any case, it is still newer than the original WinPcap and seems to work. At least, it does not look promising, since the newest version is from Oct. It is, however, not known that is the driver any longer developed.

Win10Pcap is fully free to use since it is under the GPLv2 license. Like Npcap, this is also based on WinPcap but has the support for the NDIS 6.x driver model. Yet another alternative for a packet capturing driver for Windows is Win10Pcap. If you need to make modifications to the driver’s parameters, restart the driver, e.g., from the command prompt (with administrative rights) to enable the changes. The other options shown in the figure are up to the needs – they are neither limited nor required by Qosium. See below what needs to be checked in the installation wizard.

If you choose Npcap, install it to WinPcap-compatible form.

Thus, please check the license conditions of Npcap if you are considering using it. Please bear in mind that unlike with WinPcap, Npcap’s free use is not unlimited. Npcap uses NDIS 6.x, so it should support also those NIC’s that WinPcap no longer does. Unlike WinPcap, it is under continuous development. Npcap is a newer packet capturing library, which is based on WinPcap. Thus, if your NIC works with WinPcap, there is no imminent reason to stop using it. NDIS (Network Driver Interface Specification) is the API for NICs used by Windows-based systems. Despite the fact that it has not been updated for years, and uses the nowadays deprecated NDIS 5.x, it still works with most of the system configurations even in the newest versions of Windows 10. WinPcap (version 4.1.3) is one option for Qosium. Memory buffer size is specified in parameter.In Windows, there are at least three supported alternatives for packet capturing, which are discussed in the following sections. It is written to a file when pktmon is stopped. Like circular, but the entire log is stored in memory. No limited on the number of captured events.ĭisplay events and packets on screen at real time. Log files are sequentially numbered: PktMon1.etl, PktMon2.etl, etc. New events overwrite the oldest ones when the log is full.Ī new log file is created each time the log is full.
The following modes apply to the -m or -log-mode parameter (see above). Use the following parameters for logging: Parameter Logging level for the corresponding provider. Hexadecimal bitmask that controls which events are logged for the corresponding provider. For multiple providers, use this parameter more than once. Use -t or -trace to enable event collection, along with the following optional parameters. Raw packet, truncated to the size specified in the parameter. Select packet metadata from NDIS_NET_BUFFER_LIST_INFO enumeration. Source and destination information for the first packet in NET_BUFFER_LIST group. This information is added to the end of the log file. Information about components, counters, and filters. The following flags apply to the -flags parameter (see above). Hexadecimal bitmask that controls information logged during packet capture. To always log the entire packet, set this to 0. Can be all components (all), NICs only (nics), or a list of component IDs. Use -c or -capture to enable packet capture and packet counters, along with the following optional parameters. Starts packet capture and event collection.
