Use Ethernet scanning tools to discover devices, services, and open ports on your network.
## Device Discovery
### Network Fingerprinting
Identify devices using service announcements (mDNS, SSDP, NBNS):
ethfp
See [Network Fingerprinting](/v2.1/ethernet/fingerprinting/) for detailed information.
### ARP Scanning
Discover active hosts on the network using ARP:
etharp
Returns a list of IP addresses and MAC addresses of devices responding to ARP requests.
### Ping Scanning
Scan for active hosts using ICMP ping:
ethping
Sends ping requests to discover which hosts are online.
## Service Discovery
### Banner Grabbing and Service Detection
Probe a host for running services and grab banners:
ethserv <ip>
Example:
ethserv 192.168.1.1
Attempts to connect to common ports and retrieve service information (HTTP, SSH, FTP, etc.).
## Port Scanning
### TCP Port Scanning
Scan ports on a target using range format:
ethports <ip> <start-end>
Examples:
ethports 192.168.1.100 80-80
ethports 192.168.1.100 22-443
Note: Port scanning uses range format (start-end), not comma-separated lists. To scan a single port, use the same number for start and end (e.g., 80-80). To scan common ports on the gateway, omit the port argument.
### Scan Gateway
Scan the gateway (DHCP server):
ethports local
### Scan All Ports
Scan all common ports on a target:
ethports 192.168.1.100 all
## Traceroute
Trace the network path to a host:
ethtrace <ip>
Example:
ethtrace 8.8.8.8
Shows each hop (router) between your device and the target.
## DNS Resolution
### DNS Lookup
Resolve a domain name to an IP address:
ethdns <domain>
Example:
ethdns google.com
### Reverse DNS Lookup
Resolve an IP address to a hostname:
ethdns reverse <ip_address>
Example:
ethdns reverse 8.8.8.8
## Statistics
### Network Statistics
Display Ethernet interface statistics:
ethstats
Shows packet counts, errors, and other interface metrics.
