Generating entropy can be difficult on headless systems. I used to used a debian package that generated entropy from the sound card, I've forgotten its name.
Whatever way you do it, getting entropy from the network is not considered a good idea. It could be potentially compromised.
If entropy is seriously needed then perhaps you should consider a hardware card.
