    Transparent content negotiation for the request results in a circular reference. [27] 507 Insufficient Storage (WebDAV; RFC 4918) The server is unable to store the representation needed to complete the request. [7] 508 Loop Detected (WebDAV; RFC 5842) The server detected an infinite loop while processing the request (sent instead of 208 Already ...

  4. Path MTU Discovery - Wikipedia

    en.wikipedia.org/wiki/Path_MTU_Discovery

    Path MTU Discovery (PMTUD) is a standardized technique in computer networking for determining the maximum transmission unit (MTU) size on the network path between two Internet Protocol (IP) hosts, usually with the goal of avoiding IP fragmentation.

  5. Handshake (computing) - Wikipedia

    en.wikipedia.org/wiki/Handshake_(computing)

    In computing, a handshake is a signal between two devices or programs, used to, e.g., authenticate, coordinate. An example is the handshaking between a hypervisor and an application in a guest virtual machine .

    The OpenVPN protocol is detected and blocked. Connections not using symmetric keys or using "tls-auth" are blocked at handshake, and connections using the new "tls-crypt" option are detected and throttled (under 56 kbit/s) by the QoS filtering system. [citation needed] GRE tunnels and protocols that use GRE (e.g., PPTP) are blocked. [citation ...

    This is the template test cases page for the sandbox of Template:No ping Purge this page to update the examples. If there are many examples of a complicated template, later ones may break due to limits in MediaWiki ; see the HTML comment " NewPP limit report " in the rendered page.

  9. Duplex mismatch - Wikipedia

    en.wikipedia.org/wiki/Duplex_mismatch

    Single packets are sent and acknowledged without problems. As a result, a simple ping command fails to detect a duplex mismatch because single packets and their resulting acknowledgments at 1-second intervals do not cause any problem on the network. A terminal session which sends data slowly (in very short bursts) can also communicate successfully.
