Hi, a new version of nbtscan has been released. NBTscan is a program for scanning IP networks for NetBIOS name information. It sends NetBIOS status query to each address in supplied range and lists received information in human readable form. For each responded host it lists IP address, NetBIOS computer name, logged-in user name and MAC address. Copying the old .ebuild to nbtscan-1.0.3.ebuild should do the work.

Updated. Thank you for the bug report.
