The default directory for the database is /etc/corosync/qdevice/net/. This directory has to be writable by the current user. It needs the QNetd CA certificate passed as the .B -c parameter. This certificate can be found on the server running QNetd in the file /etc/corosync/qnetd/nssdb/qnetd-cacert.crt. .TP .B -M Import a signed certificate and export a certificate with private key into pk12 file. .TP .B -m Import the cluster certificate and key from a pk12 file. .TP .B -Q Use ssh/scp to properly set both .B corosync-qnetd and .B corosync-qdevice certificates on all nodes. It's highly recommended that you use an ssh agent, or ssh/scp will keep asking for a password - roughly 8 times the number of nodes. .TP .B -r Generate a certificate request. The certificate request is exported into /etc/corosync/qdevice/net/qdevice-net-node.crq. It is necessary to pass the cluster name using the .B -n parameter. The cluster name has to match the one defined in /etc/corosync/corosync.conf. .TP .B -C Alternative remote copy command to be use in place of scp. If not specified, scp is used. .TP .B -c File with certificate to load. .TP .B -g Specify the key size to use when generating new public and private key pairs. This option is passed directly to the .B certutil command. By default, this is left empty, meaning .B -g is not passed to .B certutil at all. .TP .B -k Specify the key type to use when generating new public and private key pairs. This option is passed directly to the .B certutil command. By default, this is left empty, meaning .B -k is not passed to .B certutil at all. .TP .B -n Name of the cluster. .TP .B -S Alternative remote shell command to be use in place of ssh. If not specified, ssh is used. .TP .B -q Specify the curve-name or ml-dsa-parameter-set to use when generating new public and private key pairs. This option is passed directly to the .B certutil command. By default, this is left empty, meaning .B -q is not passed to .B certutil at all. .SH SEE ALSO .BR corosync-qnetd (8) .BR corosync-qdevice (8) .BR certutil(1) .SH AUTHOR Jan Friesse .PP
