System information

Option Description
autokill Used to control how long we wait for an ACK to our DPDISCOVER. Setting this timeout prevents the
lookups from stalling due to a latent peer. This can be yes, no, or a numeric value representing the number
of milliseconds to wait. You can use the qualify option to enable this per-peer.
secretpath A rotating key is created and stored within the AstDB. The value is stored in the key ’secret’ under the family
defined by secretpath. The default secretpath is dundi, resulting in the key being stored in dundi/
secret by default.
storehistory Used to indicate whether or not the history of the last several requests should be stored in memory, along
with how long the requests took. Valid values are yes and no (also available using the CLI commands
dundi store history and dundi no store history). This is a debugging tool that is disabled by default due to
possible performance impacts.
Table 23-2 lists the options you can configure in the [mappings] section of dundi.conf.
