[Ooops, I probably missed your previous post; I leave the following comment anyway].


Just in case, please, make sure you are including listening ports in the "netstat" inquiry (see netstat -?).

All the steps needed to run Lightstreamer are those shown in GETTING_STARTED.TXT
Obviously, the availability of a few ports for opening in listening mode is a precondition.
Is it possible that a firewall in the local machine is configured in order to forbid opening of any port in listening? Note that Lightstreamer does not negotiate its ports with firewalls, so you should make the needed ports available by acting on the firewall configuration manually.
