MacNetScan
==========

A System 7 LAN scanner for the classic 68K Macintosh. MacNetScan sweeps the
local network over Open Transport and shows, for every reachable device, a live
matrix of address, reachability, round-trip time, resolved name, and the
services it exposes -- plus AppleTalk and TCP/IP diagnostic tools. It is the
sibling project to AppleBridge and was built, compiled, and deployed through it.


What it does
------------
- IP discovery: concurrent async TCP-connect sweep of the local /24
  (open / refused / timeout), with round-trip time and a live results matrix.
- Service identification: maps open well-known ports to labels (HTTP, HTTPS,
  SMB, NetBIOS, AFP, SSH, IPP, FTP, Telnet, AppleBridge).
- Name resolution: NetBIOS (NBSTAT), multicast DNS, and reverse-DNS.
- AppleTalk: NBP device discovery across all zones, zone listing, node identity.
- TCP/IP tools: ping, DNS lookup, traceroute.
- Output: Save As tab-delimited report, or Copy to the clipboard.
- Configurable sweep: address range, timeout, concurrency, and port list.


Requirements
------------
- System 7 with Open Transport (e.g. 7.5.3+ / 7.6.1).
- 68K or PowerPC Macintosh.
- Built and tested under Basilisk II.


Authorized use only
-------------------
MacNetScan actively probes hosts on your network (port connects, NBP sweeps,
ping, traceroute). Use it ONLY on networks you own or are explicitly authorized
to scan. Scanning networks without permission may violate acceptable-use
policies or law and can trigger intrusion-detection systems. The author accepts
no responsibility for misuse.
