ppkao.com 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.

ppkao.com 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.

Warnings

The character encoding “gb2312” is not widely supported. Better interoperability may be achieved by using “UTF-8”.

Using “gbk” instead of the declared encoding “gb2312”.

The “type” attribute is unnecessary for JavaScript resources.

Attribute “'” is not serializable as XML 1.0.

Element name “sup..<” cannot be represented as XML 1.0.

The “charset” attribute on the “script” element is obsolete.

Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.

Errors

Legacy encoding “gbk” used. Documents must use UTF-8.

The only allowed value for the “charset” attribute for the “meta” element is “utf-8”.

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

Element “input” is missing required attribute “alt”.

Element “input” with attribute “type” whose value is “button” must have non-empty attribute “value”.

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

Element “ul” not allowed as child of element “h2” in this context. (Suppressing further errors from this subtree.)
