and policies. In addition to the XML policies, the /etc/syscon.conf also contains two basic parameters for
starting and controlling the SysCon service: SYSCONENABLE and SYSCONINTERVAL.
If SYSCONENABLE is not set, the daemon dies and all syscon device monitoring and logging are
disabled. SysCon devices will continue to be securely mounted but the system policies will not be in
effect. When SYSCONENABLE is set, the syscon daemon runs normally and performs checks on all
SysCon devices at a rate specified in the SYSCONINTERVAL parameter. By default SYSCONINTERVAL
is set to 10 to force a check of all SysCon devices every ten seconds.
All other values in /etc/syscon.conf are read-only and are derived from the XML SysCon policies found in
/etc/syscon/runtime/policysettings.xml. Since the SysCon device is not available at installation time (and
possibly at daemon startup), the default policysettings.xml file is used until the SysCon device is located
and mounted. From that point on, a sync action is performed at daemon startup to copy the SysCon
device’s runtime/policysettings.xml file to the system at: /etc/syscon/runtime/policysettings.xml, where it
will be used in the creation of the syscon.conf file.
12.2 Events, Notification, and Actions
12.2.1 SysCon Events
A “SysCon event” occurs whenever a device or key is inserted, mounted, changed, unmounted, or
removed. An event also occurs in the case of device/key remount failure. Each event has a device type
associated with it: Device (embedded) or Key (removable). It is important to distinguish between the two
since event actions may differ according to the associated device type.
Entry as it appears in policysettings.xml Description
SysConDevInsert Physical insertion of the SysCon device
SysConDevMntb Successful mount of the SysCon device. XML data
defines the mount point based on the physical
address of the device.
SysConDevMntFail In the case in which a mount retry is defined by
SysCon policy, this event indicates that the attempt
to remount the SysCon device has failed.
SysConDevChange Data has been written to the SysCon Device.
SysConDevUnMnt The device has been unmounted.
SysConDevRemoval Physical removal or possible failure of the SysCon
Device has been detected.
SysConKeyInsert Physical insertion of a removable SysCon Key
SysConKeyMnt Successful mount of a removable SysCon Key. XML
data defines the mount point based on the physical
address of the detected key.
SysConKeyMntFail In the case in which a mount retry is defined by
SysCon policy, this event indicates that the attempt
to remount the SysCon Key has failed.
SysConKeyChange Data has been written to the SysCon Key removable
key.
SysConKeyUnMnt The removable key has been unmounted.
SysConKeyRemoval Physical removal of the removable SysCon key has
been detected.
