(Optional) Modifying DHCP Configuration Items¶
Scenario¶
This section is only necessary for SUSE. For other OSs, skip it.
Procedure¶
In the VM OS, enter the (CLI) mode and run the su root command to switch to user root.
Run the vi /etc/sysconfig/network/dhcp command to open the configuration file.
Enter ?DHCLIENT_PRIMARY_DEVICE to locate the configuration item to be modified.
Press i to enter the editing mode, and set the value of the configuration item to yes so that the system obtains the default gateway using DHCP.
Press Esc to exit the editing mode.
Note
If DHCLIENT_PRIMARY_DEVICE does not exist in the configuration file, skip this step.
Enter ?DHCLIENT_SET_HOSTNAME to locate the configuration item to be modified.
Press i to enter the editing mode, and set the value of the configuration item to no so that the host name will not be changed when DHCP is used.
Press Esc to exit the editing mode.
Enter ?DHCLIENT_USE_LAST_LEASE to locate the configuration item to be modified.
Press i to enter the editing mode, and set the value of the configuration item to no so that the fallback to the last lease is disabled.
Press Esc to exit the editing mode.
Enter ?DHCLIENT6_MODE to locate the configuration item to be modified.
Press i to enter the editing mode and set the value of the configuration item to managed.
Press Esc to exit the editing mode.
