If you are installing AMP on a virtual machine, you may find it useful to increase the Linux kernel entropy to speed up the ssh connections to the managed entities. You can install and configure rng-tools or just use /dev/urandom`.
if you are using a RHEL-based OS: {% highlight bash %} yum -y -q install rng-tools echo “EXTRAOPTIONS="-r /dev/urandom"” | cat >> /etc/sysconfig/rngd /etc/init.d/rngd start {% endhighlight %}
if you are using a Debian-based OS: {% highlight bash %} apt-get -y install rng-tools echo “HRNGDEVICE=/dev/urandom” | cat >> /etc/default/rng-tools /etc/init.d/rng-tools start {% endhighlight %}
The following links contain further information for RHEL or CentOS, and Ubuntu.
You can also just mv /dev/random then create it again linked to /dev/urandom, by issuing the following commands:
{% highlight bash %} sudo mv /dev/random /dev/random-real sudo ln -s /dev/urandom /dev/random {% endhighlight %}
