Re: Bug: Getting dice from random.org for the second time

I searched for a switch to start GNUBG multithreaded in "man gnubg",
but didnt find one.

Then I started two instances by starting "gnubg -w" twice. I hope this
is what you meant. The flaw happens with both instances.

Afterwards I fiddled around with wireshark (though I am not a perfect
expert). I found the DNS query for random.org of the first fetching
(, Then there is some TCP traffic (probably
the random numbers).

But when GNUBG had to fetch the second portion of random numbers there
are no TCP packets, no network traffic to random.org's IP address. Not
even a single packet to this destination,
