Connection Management

Connect and configure your Ethernet interface.

Manage your Ethernet connection with configuration and status commands.

Connection Status

Check if Ethernet is connected and view link information:

ethup

Displays connection status, IP address, and link speed.

Bring down the Ethernet interface:

ethdown

ethconfig show

Displays current IP settings (DHCP or static).

Enable DHCP to automatically obtain an IP address:

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

View or modify the MAC address:

ethmac

Shows current MAC address. Use with caution—changing MAC addresses may affect network access.

time

Displays the current system time in Unix timestamp format.

settime <unix_timestamp>

Example:

settime 1703001600

Synchronize 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
