Output can be exported to XML, PostScript, CSV, or plain text.

Coloring rules can be applied to the packet list for quick, intuitive analysis.

Decryption support for many protocols, including IPsec, ISAKMP, Kerberos, SNMPv3, SSL/TLS, WEP, and WPA/WPA2.

Live data can be read from Ethernet, IEEE 802.11, Bluetooth, USB, and others (depending on your platform).

Capture files compressed with gzip can be decompressed on the fly.

Read/write many different capture file formats: tcpdump (libpcap), Pcap NG, Cisco Secure IDS iplog, Microsoft Network Monitor, and many others.

The most powerful display filters in the industry.

Multi-platform: Runs on Windows, Linux, macOS, Solaris, FreeBSD, NetBSD, and many others.

Deep inspection of hundreds of protocols, with more being added all the time.

On its website, Wireshark describes its rich feature set as including the following: It supports the same options as Wireshark. TShark is a terminal-oriented version of Wireshark designed to capture and display packets when an interactive user interface isn't necessary or available. It enables you to see what's happening on your network at a microscopic level. It lets you interactively browse packet data from a live network or a previously saved capture file. And that compared to libpcap on the systems you mentioned.Wireshark is a GUI network protocol analyzer. Would be interesting to see the difference of pcap_dump() in dumpcap and pcap_live_dump() in kdump.

However, there is sample code for a tool called kdump (at the end of the page). The function pcap_live_dump() is not used in dumpcap, so there is no way to use/test that right now.

I tend to agree with that, although I don't know the internals of WinPcap or libpcap good enough for my own (internal) final résumé.Ĭite: 'When the kernel-level traffic logging feature of NPF is enabled, the capture driver addresses the file system directly, hence the path covered by the packets is the one of the red dotted arrow: only two buffers and a single copy are necessary, the number of system call is drastically reduced, therefore the performance is considerably better.' There's no generic reason why WinPcap would be faster than libpcap on all platforms Manually choosing an "appropriate" snapshot length would work better, but that's link-layer header type dependent, and some such headers (e.g., radiotap headers) are variable-length, so it's tricky. So -s0 may mean "fewer slots", but it may also mean "you get all the bytes of the packet". If there's segmentation offloading (so that a "packet" delivered to the adapter could be bigger than the maximum Ethernet packet size), or if the adapter isn't an Ethernet adapter, libpcap will fall back on the snapshot length as the maximum packet size, otherwise it'll use the MTU + 14 bytes for the Ethernet header. the smallest needed to ensure that no packets are cut short. With newer versions of libpcap, even with -s0 (65K snapshot length) will attempt to pick a "better" maximum packet size, i.e. When capturing with the TPACKET_V1 and TPACKET_V2 memory-mapped capture mechanisms (which are the only memory-mapped capture mechanisms supported by current libpcap - TPACKET_V3 isn't currently supported - and which are used by libpcap if available), the larger the maximum packet size libpcap uses, the fewer packet slots there are. So, capturing with -s0 (65k) is a bad idea, as there are fewer slots for packets in the kernel buffer?
