Nmap, short for Network Mapper, is a free, open-source tool for vulnerability scanning and network discovery. Network administrators use Nmap to identify what devices are running on their systems, discovering hosts that are available and the services they offer, finding open ports and detecting security risks.

Yes, but only if you had a spyware inside your machine. Because out of it, the whole message traffic is encrypted using SSL, which means if someone try to intercept your conversation, all they'll see will be a unreadable text.

I can't say for certain, but, in this case, given the networking problems you're describing, "NBSS Continuation Message" probably means that the "previous segment" wasn't captured because it didn't make it to the machine running Wireshark, i.e. a packet got lost in transit between 192.168. 69.236 and 192.168. 69.245.
