corosync-keygen - Generate an authentication key for Corosync. SYNOPSIS
corosync-keygen [-l] DESCRIPTION
If you want to configure corosync to use cryptographic techniques to ensure authenticity and privacy of the messages, you will need to generate a private key. corosync-keygen creates this key and writes it to /etc/corosync/authkey. This private key must be copied to every processor in the cluster. If the private key isn't the same for every node, those nodes with nonmatching private keys will not be able to join the same configuration. Copy the key to some security transportable storage or use ssh to transmit the key from node to node. Then install the key with the command: unix#: install -D --group=0 --owner=0 --mode=0400 /path_to_authkey/authkey /etc/corosync/authkey If a message "Invalid digest" appears from the corosync executive, the keys are not consistent between processors. Note: corosync-keygen will ask for user input to assist in generating entropy unless the -l option is used. OPTIONS
-l Use a less secure random data source that will not require user input to help generate entropy. This may be useful when this utility is used from a script. EXAMPLES
Generate the key. $ corosync-keygen Corosync Cluster Engine Authentication key generator. Gathering 1024 bits for key from /dev/random. Press keys on your keyboard to generate entropy. SEE ALSO

corosync-objctl - Configure objects in the Object Database SYNOPSIS
corosync-objctl [-b] [-c|-w|-d|-a|-t-h] <OBJECT-SPEC>... DESCRIPTION
corosync-objctl is used to configure objects within the object database at runtime. OBJECT-SPEC There are two types of entities Objects and Key=Value pairs Objects Objects are container like entities that can hold other entities. They are specified as "objectA"."objectB". An example is log- ging.logger. Key=Value pairs These are the entities that actually hold values (read database "fields"). They are specified as object.key=value or just object.key if you are reading. OPTIONS
-c Create a new object. -d Delete an existing object. -w Use this option when you want to write a new value to a key. -a Display all values currently available. -t Track changes to an object and it's children. As changes are made to the object they are printed out. this is kind of like a "tail -f" for the object database. -h Print basic usage. -b Display binary values in BASH backslash escape sequences format. EXAMPLES
Print the objOne object (shouldn't exist yet). $ corosync-objctl objOne Create the objOne object. $ corosync-objctl -c objOne Print the objOne object (empty). $ corosync-objctl objOne objOne Write two new keys to the objOne object. $ corosync-objctl -w objOne.max=3000 objOne.min=100 Print the objOne object (with the two new keys). $ corosync-objctl objOne objOne.min=100 objOne.max=3000 Delete the objOne.min key $ corosync-objctl -d objOne.min=100 Prove that is gone. $ corosync-objctl objOne objOne.max=3000 Delete the whole objOne object. $ corosync-objctl -d objOne Prove that is gone. $ corosync-objctl objOne SEE ALSO
