Siocsifflags: cannot assign requested address

[[Email protected] ~] # Ifconfig eth0: 1 up
Siocsifflags: cannot assign requested address

 

The reason for the above error is the eth0: 1 information written in the ifcfg-eth0: 1 configuration file, the intention is to, automatically load when the boot, to achieve a Dual IP card.

However, when the eth0: 1 device is manually down ("ifconfig eth0: 1 down" is executed), the above error is reported when the device is enabled again, mainly because the MAC address is repeated.

Solution:

1. Manually allocate a MAC address (not recommended)

2, manually execute the command to add IP, written in the ifcfg-eth0: 1 in the information configuration, such

Ifconfig eth0: 1 192.168.1.2/24

Route add default GW 192.168.1.1 Dev eth0: 1
