The "DoS" page has been changed by GuillermoGrandes: http://wiki.apache.org/httpd/DoS?action=diff&rev1=9&rev2=10 Comment: link to patch --(The slowloris script is also a big CPU drain on its own host. Running it on my opensolaris box, it took around 50% of the CPU (as shown by top(1)) to hold 252 connections open and trickle data. On linux it was over 99% to hold 1020 connections. Running both slowloris and apache on the linux box, apache responded effortlessly to /server-status requests while servicing the slowloris attack, all while sharing the <1% of CPU left by slowloris with top and the Gnome desktop.)-- - ['''Update: 29.Apr.2011'''] slowloris-perl can be patched (1 line) to reduce CPU drain... (only use 2%, 500 connections in linux-box/threaded, this crash typical server in 15 seconds) + ['''Update: 29.Apr.2011'''] slowloris-perl can be [[http://pastebin.com/z3cveHKA|patched]] (1 line) to reduce CPU drain...
