XBSSNAPSHOT(1)                                  CoreXBS Tools                                 XBSSNAPSHOT(1)



NAME
       xbssnapshot - CoreXBS snapshot utility

SYNOPSIS
       xbssnapshot fetch [--[no]live] [--age hours] [--[no]xpc] train_name

       xbssnapshot authcheck [--timeout seconds] train_name

DESCRIPTION
       In  the 1st form, xbssnapshot is used to obtain a snapshot of Cortex for train_name. A cache of snap-shots snapshots
       shots is maintained in a directory, which may or may not be used in addition to consulting the Cortex
       servers depending on command line OPTIONS specified. If successful, a file URL of a suitable snasphot
       is printed to STDOUT. On failure, a description of the failure is printed to STDERR.

       In the 2nd form, xbssnapshot is used to check connectivity to the Cortex servers for  train_name  and
       determine  if AppleConnect (Single Sign-On) credentials will be required to obtain a snapshot. If the
       Cortex server can be reached, YES is printed to STDOUT if SSO authentication is required  and  NO  is
       printed  if  not. On failure (including not being able to reach the Cortex servers), a description of
       the failure is printed to STDERR.

OPTIONS
       --live Force xbssnapshot to bypass the snapshot cache directory and fetch data from Cortex.

       --nolive
              Force xbssnapshot to not fetch data from Cortex and only use the snapshot cache directory.

       --age hours
              When considering if a snapshot found in the snapshot cache directory  is  "new  enough",  only
              accept snapshots that are less than hours old.

       --xpc  Use XPC service when fetching data from Cortex. This is the default.

       --noxpc
              Bypass XPC service when fetching data from Cortex.

       --timeout seconds
              When  performing  connectivity test with Cortex server(s), how long to wait before assuming no
              connectivity to a given Cortex server.

RETURN VALUES
       Returns 0 on success, and non-zero on failure.

ENVIRONMENT
       CTXHost
              May be set to the hostname of a specific Cortex server. This is  mainly  only  useful  to  the
              developers.

       CTXPort
              May  be  set  to  specific  port to connect to CTXHost on (does nothing unless CTXHost is also
              set). This is mainly only useful to the developers.

FILES
       /Library/Caches/com.apple.bni.cortexsnapshot
              Directory where snapshots are cached.

       /var/log/system.log
              CoreXBS framework and XPC services log here. grep CoreXBS /var/log/system.log may  show  addi-tional additional
              tional information above and beyond what xbssnapshot prints on it's own.

BUGS
       If you encounter issues with xbssnapshot, please file a Radar. Component is "CBL - CoreXBS|X". Please
       include the following information, if possible:

       1.  Output of xbssnapshot, including command line it was invoked with.

       2.  Output of ls -lh /Library/Caches/com.apple.bni.cortexsnapshot

       3.  Output of grep CoreXBS /var/log/system.log

       4.  If a snapshot was fetched, a copy of the snapshot.
