Generate a Solr Password Hash
Recent versions of Solr allow restricting access via authentication and authorization plugins, for instance the basic authentication plugin. The documentation shows an example security.json
that you can upload into Zookeeper (assuming that you're running SolrCloud).

Useful settings for grub on Debian
Boot a kernel just once
If you want to test a new kernel without having access to the console you need to make sure that the system comes back up with the old kernel if the new one panics. Add a setting panic=2
to the kernel commandline in /etc/default/grub
to have the system automatically reboot in case of a kernel panic, and tell grub to boot a saved kernel by default:
GRUB_DEFAULT="saved"
GRUB_CMDLINE_LINUX="panic=2"

IPMI interface network configuration from Linux
Load the relevant modules, either via modprobe
or by entering them into /etc/modules
(so they're loaded automatically on the next system startup).
modprobe ipmi_devintf
modprobe ipmi_si
