This provides documentation beyond what is in the tool's help text.
An IP address or hostname, password, and username are required for connecting to a BMC.
These are passed in with the following options:
-H: The hostname or IP for the BMC-U: The username-P: The password, provided in-line-A: Prompt for a password. Can be used in place of -P.The local user accounts on the BMC, such as root, can be disabled, queried, and re-enabled with the 'local_users' sub-command.
Important: After disabling local users, an LDAP user will need to be used for further interaction with the BMC, including if using openbmctool to enable local users again.
To view current local user account status:
openbmctool <connection options> local_users queryenabled
To disable all local user accounts:
openbmctool <connection options> local_users disableall
To re-enable all local user accounts:
openbmctool <connection options> local_users enableall
The BMC has the ability to stream out local logs (that go to the systemd journal) via rsyslog.
The BMC will send everything. Any kind of filtering and appropriate storage will have to be managed on the rsyslog server. Various examples are available on the internet. Here are few pointers: https://www.rsyslog.com/storing-and-forwarding-remote-messages/ https://www.rsyslog.com/doc/rsyslog%255Fconf%255Ffilter.html https://www.thegeekdiary.com/understanding-rsyslog-filter-options/
openbmctool <connection options> logging remote_logging_config -a <IP address> -p <port>
The IP address and port to be provided are of the remote rsyslog server. Once this command is run, the remote rsyslog server will start receiving logs from the BMC.
Hostname can be specified instead of IP address, if DNS is configured on the BMC.
openbmctool <connection options> logging remote_logging disable
It is recommended to disable remote logging before switching remote logging from an existing remote server to a new one (i.e before re-running the remote_logging_config option).
openbmctool <connection options> logging remote_logging view
This will print out the configured remote rsyslog server's IP address and port, in JSON format.
