9.2. Connectivity Between the Host and BMC
You can congure internal network connectivity between the host and the BMC rather than using
external network connectivity and routing trac outside the host.
To congure internal network connectivity, you must congure an interface on the 169.254.0.0∕
255.255.0.0 network. The interface can then send and receive Redsh API trac between the host
and the BMC. The BMC is precongured to use the 169.254.0.17 IP address.
Run an ifconfig command like the following example to congure connectivity:
sudo ifconfig enx9638a3b292ec 169.254.0.18 netmask 255.255.0.0
Replace the network interface name and IP address in the preceding example according to your needs.
After you congure the network interface, you can use commands such as curl and nvfwupd with
the 169.254.0.17 IP address to connect to the BMC and use the Redsh API.
The following example command shows the rmware versions:
nvfwupd -t ip=169.254.0.17 username=<bmc-user> password=<password> show_version

▶ Accounts
The following curl command changes the password for the admin user.
curl -k -u <bmc-user>:<password> --request PATCH 'https:∕∕<bmc-ip-address>∕
,→redfish∕v1∕AccountService∕Accounts∕1' --header 'If-Match: *' --header 'Content-
