I finally muddled my way through building the latest httpd trunk code (I couldn't work out if/how it's possible to just build ab without the rest of httpd), so now have a version of 'ab' which supports testing of ChaCha20-Poly1305. :) In case it's useful to anybody else, here are the steps I used: # apply any updates and install pre-requisites sudo apt-get update sudo apt-get upgrade sudo apt-get install libapr1 libapr1-dev libaprutil1 libaprutil1-dev libpcre3 libpcre3-dev subversion autoconf libtool libtool-bin # move to home folder and create a folder where to build into cd ~ mkdir httpd-install # get the latest source and unzip it (to ~/httpd-trunk) wget https://github.com/apache/httpd/archive/trunk.zip unzip trunk.zip cd httpd-trunk # get the latest APR source and put it in '[httpd source root]/srclib/apr' (required for the build) svn co http://svn.apache.org/repos/asf/apr/apr/trunk srclib/apr # configure the things chmod +x buildconf ./buildconf ./configure --prefix=/home/pi/httpd-install/ --with-included-apr # make and install make make install # create a symlink to our bleeding-edge version of ab, so we can just call it using 'ab' sudo ln -s /home/pi/httpd-latest-install/bin/ab /usr/bin/ab Boots UK Limited, Registered 928555, Nottingham NG2 3AA This e-mail (including any attachments) is confidential.
