Eddie, Thanks for the pointer. I can definitely see where multiple scripts waiting to bind the same originating port could cause some serious resource contention. I wonder, though, if it would make sense to implement a function that creates outbound connections from so-called privileged ports, without trying to specify what that port might be. There are a still a number of network services that just won't talk to clients from unprivileged ports. Even if we restrict ourselves to the top half of the privileged port range to avoid contention with common network services, we still have over 500 ports to choose from. Since NSE defaults to a limit of 10 concurrent connections, we shouldn't have to worry too much about resource contention. Perhaps something to think about, at least. Anyway, I think for now I'll look at other options for my rsh-based discovery script. Thanks, Thomas _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://SecLists.Org
