Give PHP read access to /dev/urandom

Hey there,

I’m trying to follow the steps in
and I’m stuck at giving php read access to the /dev/urandom device.

The instruction puts it in one sentence to “simply” give php read access - but how? What do I have to write into the pho.ini-file (considering the change needs to be done to that file!) ?

I hope someone can help me.

Find your php.ini file.

updatedb && locate php.ini

Edit the php.ini file, the one with apache with it.
Search for open_basedir = and edit it to become

open_basedir = /dev/urandom

Restart apache
