Linux finally ran up last night and the file system was ready for use. When I started the system, I called ifconfig to set the IP address. However, it always showed: ifconfig: siocsifflags: cannot assign requested address: I checked it online. It turned out to be a problem with the MAC address. After the following processing, it will be OK ~ # Ifconfig eth0 down
# Ifconfig eth0 HW ether 00: 00: AA: BB: CC: dd
# Ifconfig eth0 up
Eth0: link down
# Ifeth0: link up, 100 Mbps, full-duplex, LPA 0xcde1
# Ifconfig eth0
