Port-Range / TCP/UDP about portauthority HOT 4 CLOSED

Thanks for the feedback! Definitely some good suggestions :) I'm glad to hear that you find it useful.

Can I ask what phone/tablet you're using when you run Port Authority? The reason why I ask is because it's possible for old hardware to have a hard time handling scanning MANY ports like you mentioned. This is because, internally, I am using many threads which is one of the big factors that give Port Authority its speed.

Can you elaborate on the issues you're seeing with host name resolution? The tricky thing with resolving host names on a local network is that a lot of factors are up to the router as far as how it provides host names. For example, the router I have gives some weird values for my FQDN. Also, some routers won't provide DNS by default at all. What I think I should do is probably support DNS as well as NetBIOS/WINS to make sure I am able to get the most accurate information I can. This is on my todo list.

UDP port scanning will come later. I think it's going to be a pain to do it in Java, especially without root access. The nmap docs and wikipedia have some good explanation on this https://en.wikipedia.org/wiki/Port_scanner#UDP_scanning

Ideally I'd want to drop down to C via JNI in order to have more control, but then the things I'd want to do would require root access which I don't want to enforce on users. I'll have to think about the best way to implement UDP scanning that's fairly accurate and reliable without being able to use raw sockets or JNI...

I'll be rolling out 1.6 soon which will let you scan WAN hosts now. See 8932e6b :)

I just rolled out 1.6.2 which should GREATLY improve the issue you're seeing with the app freezing when scanning many ports.
