April 27, 2000 (GMT +8) Hello world, Can anybody point me to a detailed reference on how VDOLive works? Looking at my tcpdump output, connecting to a site involves connections from three servers, and not just the original one I was originally browsing. Very firewall unfriendly. 1] My PC connects via TCP/7000 to 203.116.81.41 http://onezine.s-one.net.sg/s-onezine/980619M/SCV_roadshow/calendarone.vdo from this URL webpage: http://onezine.s-one.net.sg/s-onezine/980619M/SCV_roadshow/index.htm 2] The weird thing is that 203.116.81.59 is sending stuff to my PC via an arranged UDP high-port, which my PC was waiting to accept (as seen by "netstat -na"). FW-1 naturally denies this unknown connection, but I still hate knowing their is a race condition between the VDOLive server and some lucky crackers. 3] The 2nd weird thing is that my PC again connects via TCP/7010 to 207.88.23.100 (vdo-ds3.vdo.net). What in the world is VDONet's role in here? I tried it both from outside/inside my FireWall-1, and there is no obvious participation (e.g. no ads, nor anything) from VDONet. thanks in advance, Drexx Laggui <drexx () pacific net sg>
