FreeNET needs some good random data to startup.
When the node start it can take some time getting this data and this message is going to appear:



Freenet is starting up
Not enough entropy is available!
There isn’t enough entropy available on your system… Freenet won’t start until it can gather enough.



To avoid this or speedup the process you can generate some entropy doing some random hard disk drive seeks. You can use this little program to do that (and also know the average random seek of your hard disk drive):

user@computer:$ wget http://www.linuxinsight.com/files/seeker.c
user@computer:$ gcc -O3 seeker.c -o seeker
user@computer:$ sudo ./seeker /dev/sda
Benchmarking /dev/sda [238475MB], wait 30 seconds.............................
Results: 54 seeks/second, 18.46 ms random access time
