Manage your Ethernet connection with configuration and status commands.
Note: Ethernet is available only on the Banshee S3 build (CONFIG_WITH_ETHERNET).
Tip: The Ethernet interface can be used with the DNS sinkhole - once connected via Ethernet, sinkhole start will use the Ethernet IP automatically. See [DNS Sinkhole](/latest/wifi/dns-sinkhole/) for details.
Check if Ethernet is connected and view its IP configuration with ethup:
ethup
Prints the IP address, subnet mask, gateway, DNS servers, and DHCP server. It does not show link speed.
Show link status, speed, duplex, MAC, and IP details with ethinfo:
ethinfo
For example, ethinfo reports the negotiated link (such as 100Mbps Full Duplex) and the interface MAC address.
Bring the interface down with ethdown:
ethdown
## Configuration
View the current IP settings (DHCP or static):
ethconfig show
Enable DHCP to obtain an IP address automatically:
ethconfig dhcp
Set a static IP address:
ethconfig static <ip> <netmask> <gateway>
Example:
ethconfig static 192.168.1.100 255.255.255.0 192.168.1.1
## MAC Address Management
View the current MAC address:
ethmac
Set a custom MAC address with ethmac set. Use with caution-changing MAC addresses may affect network access.
ethmac set <xx:xx:xx:xx:xx:xx>
## System Time
Display the current system time including local time, UTC time, and Unix timestamp:
time
Set the system time:
settime <unix_timestamp>
Example:
settime 1703001600
Synchronize the system time with an NTP server:
ethntp <time_server>
If no server is specified, uses pool.ntp.org by default:
ethntp
Example with custom server:
ethntp time.nist.gov
