Script `http-chrono`

Script types: portrule
Categories: discovery, intrusive
Download: https://svn.nmap.org/nmap/scripts/http-chrono.nse

Script Summary

Measures the time a website takes to deliver a web page and returns the maximum, minimum and average time it took to fetch a page.

Web pages that take longer time to load could be abused by attackers in DoS or DDoS attacks due to the fact that they are likely to consume more resources on the target server. This script could help identifying these web pages.

Script Arguments

http-chrono.tries: the number of times to fetch a page based on which max, min and average calculations are performed.
http-chrono.withindomain: only spider URLs within the same domain. This widens the scope from withinhost and can not be used in combination. (default: false)
http-chrono.withinhost: only spider URLs within the same host. (default: true)
http-chrono.maxdepth: the maximum amount of directories beneath the initial url to spider. A negative value disables the limit. (default: 3)
http-chrono.maxpagecount: the maximum amount of pages to visit. A negative value disables the limit (default: 1)
http-chrono.url: the url to start spidering. This is a URL relative to the scanned host eg. /default.html (default: /)
slaxml.debug: See the documentation for the slaxml library.
httpspider.doscraping, httpspider.maxdepth, httpspider.maxpagecount, httpspider.noblacklist, httpspider.url, httpspider.useheadfornonwebfiles, httpspider.withindomain, httpspider.withinhost: See the documentation for the httpspider library.
http.host, http.max-body-size, http.max-cache-size, http.max-pipeline, http.pipeline, http.truncated-ok, http.useragent: See the documentation for the http library.
