Pardon me here, as I don't mean to belittle your considerable efforts, but I  
think it was a mistake to make such loud announcements (posted to sci.crypt  
for instance) when the software was alpha!  The software should have been  
tested and stable before the general public was invited to participate and  
"see how fast we can break SSL"  As expected, lots of people tried to  
participate and the software just couldn't handle it.

How many patched versions of the client software were distributed after the  
effort had started?  If you want to do it as fast as possible, you can't be  
constantly updating your client software.

I think protocol issues are a Red Herring.  If your server had been able to  
handle more than one client at a time it would have stood a chance.  Why  
didn't it fork?  Sure, forking isn't the most efficient way to handle  
multiple clients, but HTTP servers (as well as SMTP and FTP) manage to handle  
hundreds of thousands of requests each day that way.  One client at a time  
with a 30-second timeout was just plain dumb...


I would recommend thorough testing of the software on many platforms and with  
realistic loads before the next public effort (there are plenty of willing  
testers on the cypherpunks list).  I tried to join in the effort and after  
discovering that the client software was firing off multiple brutessl  
processes, I decided to wait until the client stabilized.  I attempted to  
reject the keyspace I allocated through the WWW interface, but that didn't  
even work!!
