Switch to /dev/urandom - it exists exactly for that purpose.

NICs should not participate in the entropy pool, because they are exposed to the outside world and can thus be influenced from the outside, degrading the randomness of the /dev/u?random output.. -- Oleg Goldshmidt | [EMAIL PROTECTED] ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
