/dev/urandom is a hack. In a perfect world, the /dev/random device would be able to return a string of random numbers as fast as you wanted, and there would not have been a need for /dev/urandom
Since FreeBSD tries to be close to perfect ;-) it uses a better random driver that can produce random numbers as fast as you want them. The symlink is there only as a crutch for older UNIX code that was written when there was a difference between /dev/random and /dev/urandom Ted > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Roland Smith > Sent: Thursday, September 13, 2007 8:37 AM > To: Per olof Ljungmark > Cc: email@example.com > Subject: Re: /dev/random question > > > On Thu, Sep 13, 2007 at 04:56:26PM +0200, Per olof Ljungmark wrote: > > Hi, > > > > Could someone on the list point me to a document that explains the > > functionality of /dev/random in FreeBSD in a little more depth > than the man > > page?
