I'm developing some ********* gnutella application, and I need to test it with bearshare. The problem is that I've never been ultrapeer, even if I have an excellent connection, and remain up several days in a row (an reconnect again in short time). Any suggestions?
Someone recommended me to use old beta versions of bearshare but one of them I tried just showed me a message saying "Expired".
Thanks, M

You would also need BearStart to run those betas.
See this thread for the right betas and BearStart:
Sticky: BearShare has been sabotaged. (1 2 3 4 5 )

thanks Aaron, I only changed the date manually, and it worked. the Bearshare beta opened. Then I selected the option, restarted all connections, and that's it! I'm a good ultrapeer, I deserve to be treated as a good one, =)

the BearStart.exe utility is great because it only temporarily changes the date..after about 15 seconds it is returned to normal, so any other things you are doing which need a correct time/date stamp are OK
