USAGE:
  n a .                                every socket on this machine

Target: . = this machine · <host> = remote
Deeper: n a -h = the concept/theory behind this command

The concept behind it — n all -h

COMMAND HELP:
  You can type "n <command> -h" (or "n -h <command>") for in-depth help:

  Connectivity & Discovery:
    n check -h         4-stage triage ladder & remote host diagnostic manual
    n ping -h          Who Am I loopback, subnet sweeps, IP ranges & reachability
    n resolve -h       Multi-protocol resolution & finding stale ghost IPs
    n flush -h         Deep cache reset (DNS, NetBIOS, ARP, Samba)
    n host -h          LAN visibility, WSD, mDNS & firewall configuration

  Ports & Sockets:
    n l -h             Listening sockets, port ranges & Docker mapping
    n e -h             Established active connections & socket leaks
    n a -h             Master socket exploration reference (all states + UDP)
    n <PORT> -h        Single port inspection, IANA service lookup & containers
    n k -h             Safely terminating processes locking ports (e.g. n k 3000)

  Services & Workloads:
    n web -h           Web service discovery, HTML titles & clickable OSC-8 links
    n svc -h           Service & daemon inventory, filtering OS noise
    n d -h             Docker container port mapping & inspection

  Incident Response & Hardware:
    n fw -h            Firewall rule inspection & port access verification
    n top -h           Busiest remote IPs (who's connected most) & reverse DNS
    n choked -h        Stalled process / full Recv-Q backlog detector
    n drops -h         NIC interface health, dropped packets & CRC errors
    n sys -h           Hardware, OS, CPU, RAM, disk & shares inventory

SPECIALIZED INCIDENT RESPONSE PLAYBOOKS:
  Type "n -h <topic>" to read deep engineering playbooks:
    n -h cgnat         Carrier-Grade NAT (RFC 6598), shared IPs & port-forwarding
    n -h rtt           Round-trip latency benchmarks & ICMP packet loss
    n -h wins          NetBIOS, WINS, Samba gencache & exorcising ghost IPs
    n -h ssh-windows   SSH into Windows: the two authorized_keys files & UAC elevation
    n -h ports         Open vs Closed (RST) vs Filtered (Drop) socket states
    n -h ssl           HTTPS certificates, CAs, cipher suites & expiry dates
    n <verb>          Usage for any command · n <verb> -h for the concept behind it

QUICK EXAMPLES:
  n ping               # Who Am I loopback & local adapter audit
  n ping 192.168.1.0   # Scan entire local subnet for active devices
  n check              # 4-stage network triage (GW -> WAN -> DNS)
  n check 1.1.1.1      # Full diagnostic triage on target host
  n l 8000 9000        # Audit listening ports in range 8000-9000
  n web                # Find active web dashboards with clickable links
  n k 3000             # Safely kill process locking port 3000
  n resolve dell1      # Check DNS, mDNS, NetBIOS & ARP side-by-side
  n flush              # Deep cache flush across DNS, NetBIOS & ARP
