| Netscan X Feature | Alternative Tool / Method | Key Details | |------------------|---------------------------|--------------| | | arp-scan (local subnet) + nmap -sn | arp-scan is faster on LAN; nmap -sn works across routed networks. | | OS fingerprinting | nmap -O | Uses TCP/IP stack quirks; less accurate than commercial but free. | | Port scanning | nmap -sS -sU -p- | SYN + UDP scan; -p- = all ports (slow). Use --top-ports 1000 for speed. | | SNMP walk (read) | snmpwalk -v2c -c public <ip> .1.3.6.1.2.1 | Retrieves full MIB-II: interfaces, ARP, routes, system description. | | SNMP v3 support | snmpwalk -v3 -u user -l authPriv ... | Works with SHA/AES. | | Device type detection | nmap -O + snmpwalk sysDescr | Combine: Cisco vs. printer vs. Linux. | | MAC vendor lookup | arp-scan --local (includes vendor OUI) | Uses /usr/share/arp-scan/ieee-oui.txt . | | Export to CSV/XML | nmap -oX + xsltproc | Built-in XML; convert to HTML/CSV with nmap.xsl . | | Scheduled scans | Cron + nmap | 0 2 * * * nmap -sn 192.168.1.0/24 > /var/log/netscan.log | | Graphical network map | Zenmap (nmap GUI) | Topology view available via “Network Map” tab. | | Large subnet (e.g., /16) | masscan --rate=10000 | Can scan entire internet in minutes; use with caution. | | IP range monitoring (changes) | ndiff (part of nmap) | Compares two XML outputs: added/removed hosts, changed ports. | | Service detection | nmap -sV | Version probes for HTTP, SSH, FTP, etc. | | Web GUI dashboard | Zabbix (auto-discovery + SNMP) | Learns network, graphs interface traffic, alerts on down hosts. | | Lightweight portable version | nmap (portable) + WinPcap | Runs from USB on Windows. |
