Thanks for the report. Can you please confirm that error cases 1 and 4 persist with the recently released version 1.0.3? This seems to be similar to #1. Error cases 2 and 3 indicate that you are trying to use -listen (which is meant for scanning clients) with a remote IP address. Given the case that you are trying to scan a server, the commands in 1 and 4 are correct.
