The OP is somewhat mistaken about entropy sources within a modern system.
A modern OS implementation keeps a record of the number of shannons of entropy available in the /dev/random pool and only allows that amount to be taken out.
The /dev/urandom pool simply allows the user to continue removing bits of data when there are no shannons of entropy left in the pool.
The only way to acquire more shannons of entropy to fill the /dev/random pool (and hence provide a way for /dev/urandom pool to also acquire more) is to have a physical source of truly random nature.
Such sources can include the timing information of key presses which introduce fractions of a shannon of entropy but network activity of any type is disturbingly periodic, hence such sources have largely been removed.
If you want a true random number generator you need something like an Entropy key which uses physical quantum phenomena to generate many shannons of entropy continuously.

Debian

+ - Debian conference final report

Apparently around four hundred Debian developers went and had fun in Edinburgh. As would be expected an interesting selection of talks occurred but more interesting were their other activities which included dancing around in skirts and organ repair!

Hopefully their conference will assist them to release an updated release soon and gain back some of the ground lost to Ubuntu and the other derivatives which seem much more appealing these days."
