/dev/random is blocking because it oesn't get random bits from anywhere.
For networked computers, the most likely error source is a broken
Ethernet driver. For computers you're sitting in front of, just switch
to a different terminal an bang a few keys. ;-)

If all else fails, use /dev/urandom, which uses an internal hash
function instead of blocking when it runs out of bits. I'd say that for
most if not all uses, /dev/urandom is perfectly OK.
