biodiversitylibrary.org Ping

Ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It measures the round-trip time for messages sent from the originating host to a destination computer that are echoed back to the source.

biodiversitylibrary.org TRACEROUTE

Traceroute is a computer network diagnostic tool for displaying the route (path) and measuring transit delays of packets across an Internet Protocol (IP) network. The history of the route is recorded as the round-trip times of the packets received from each successive host (remote node) in the route (path); the sum of the mean times in each hop is a measure of the total time spent to establish the connection. Traceroute proceeds unless all (three) sent packets are lost more than twice, then the connection is lost and the route cannot be evaluated.

biodiversitylibrary.org HTML validation

Errors

A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.

Stray end tag “link”.

Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

No space between attributes.

Quote “'” in attribute name. Probable cause: Matching quote missing somewhere earlier.

Bad value “” for attribute “id” on element “div”: An ID must not be the empty string.

Attribute “time” not allowed on element “a” at this point.

Text run is not in Unicode Normalization Form C.

Attribute “:” is not serializable as XML 1.0.

Attribute “-” is not serializable as XML 1.0.

Attribute “crustaces,” is not serializable as XML 1.0.
