I have a DirectAdmin server and executed this command a while back:
Is it possible to make PHP more secure using the CustomBuild script?
Yes, it is. You need to run “./build secure_php”. At the moment it disables some dangerous PHP functions as:
exec, system, passthru, shell_exec, escapeshellarg, escapeshellcmd, proc_close, proc_open, dl, popen, show_source
Now auto archiving is not working anymore, probably because it uses one of this functions. I can’t find which function is being used by Piwik. Does anyone know this?
