SECREFHRELTD USA, AUS, CAN, GER, NZL Royale With Cheese Updater Read Me Dyeryiew The Royale with Cheese Updater is the mechanism by which dictionaries are updated. It requires each node in a giyen network that is being updated to ful?ll at least one of two roles: Publisher or Subscriber. A Subscriber refers to any machine that receiyes dictionary updates. A Publisher refers to any machine that sends updates to Subscribers. In this sample set?up, irks?control acts only as a Publisher and all other nodes act as a Subscriber. thhe Subscriber nodes, alts?1, lurks?2, and KkS-ll? act as both Subscribers and Publishers. They subscribe to the node that is higher in the hierarchy le.g., IKE-1 subscribes to irks?control}, but they also publish to nodes that are lower in the hierarchy fe.g., aka?1 publishes to HkS-lb}. r? amfgs?contrpi?j ram?Rica For? .?a'lniE- 1 If, ?k5 2>c_ Jeff? a Ffa'I-I-l --. ..- l' -I-. ff! irks-lo Ilf'j-llil j) (lab-1c iota-2a Cycles-Eb (tilts?2c :1 r? alts i5?

To manually ?link? a Subscriber to a specific Publisher, use the rwc_Pub isher option in xksconfig Anatomy of an Update Each dictionary update is initiated by the Subscriber HkS-l or HkS?lb} and proceeds as follows: 1. Dn an hourly basis, the rwc_post_to_pub script sends the Subscriber?s current inyentory to its Publisher. 4 usa, aus, can, can, NZL

SECREFHRELTD USA, AUS, CAN, GER, MEL 2. Each file that the Publisher is configured to publish is compared against the same file in the Subscriber's inyentory. There are four possible results: a. (UIIFDUCI) The Publisher does not haye a file which the Subscriber listed. The Publisher will tell the Subscriber to delete its copy of the file. b. The Publisher has a file that the Subscriber is missing. The Publisher will send the Subscriber a copy of the file. c. The Publisher has the file, but the Publisher's yersion has a different hash than the Subscriber?s. This should only occur when the Publisher has a newer yersion of a file, and the Publisher will send its yersion of the file to the Subscriber. d. The Publisher has the file and both hashes are the same. The Subscriber is up to date and the Publisher makes no change to the Subscriber's inyentory. 3. The Publisher creates a binary file that contains all files that need to be downloaded to the Subscriber. The binary file is split into some number of n?byte chunks. The size of these chunks is determined by the rwc_mas_chunk option in sks.config ii. Hashes are generated for each chunk. The Publisher then sends a list of the locations {urls} of the chunks {partials} and the hashes to the Subscriber. S. Dnce the Subscriber receiyes the PL list, it downloads each partial file from the Publisher. Note: The download of a partial must fail 1D times before the update stops. En. When each download is finished, the Subscriber checks the hash of the file it has with the hash sent by the Publisher. If any of the partial hashes do not meet the expected yalue, the update stops. If the download completes successfully, the Subscriber recombines the partial chunks into the original binary file. Note: When the post?to?pub script runs {Step it first checks to make sure it is not already in the middle of a download. If, for some reason, the update could not complete the preyious download, it will restart from the partial file at which it stopped. This functionality was implemented to help some slower sites that were haying difficulty completing the download of a full dictionary. The Subscriber installs the shipment and updates its inyentory. Note: The current yersion of each file can be updated on a Publisher by running the script that re?computes the hash es for each file for which the Publisher generates updates. By default, this happens eyery hour on the half hour. 5 use, wus, can, see, NZL

Similar, Control has no Publishers. ts Subscriber options are ignored. Publishers such as Masters and Proxies, howeyer, can be both Subscribers to other Publishers AND Publishers to Subscribers that are below them in the hierarchy. For example, xks?l, xks?E and xks?1b are each Publishers and Subscribers. Each uses both Publisher and Subscriber options. if FDUD) Publish er ?btions Publishers use xks.rwc.config to publish, add and remoye files and directories. Hemoye functions are always run last after eyaluating all other options: Publish pub_xx: Any option in the config file that begins with "pub" indicates that the current machine can act as a Publisher for the giyen package, xx. For example, pub_metadata_forwarder is an option that determines if you want your slaye machines to receiye metadata forwarder packages. By setting Publisher?s yalue tofulse, pub_metadata_forwa rd er false, no machine that subscribes to this option will receiye the associated files. Hemoye The remoye option flags anyfiles or directories that should be remoyed from the Subscriber. For example, suppose the Publisher is set to not publish the forwarding whitelist but the whitelist is part of the default dictionaries which are automatically included as part of an upgrade. In this case, in spite of the fact that the whitelist is in neither the Publisher?s nor the Subscriber?s inyentory, you will need to remoye it.

Howeyer the ignoreand commend options can be used to tailor the Subscriber to accommodate its own unique scenario. Sub_:or: Any option in sks_rwc.config that begins with "sub" indicates whether the current machine will or will not accept a giyen package, lot, from its Publisher. For example, sub_metadata_forwarder is an option that determines if you want the Subscriber to accept the forward_metadata package. If a particular Subscriber?s prosy yalue is set tofoise, sub_metadata_fonryarder false, then that Subscriber will not receiye the associated files. Eyen if the corresponding option on the Publisher is set to true, no modules will be deliyered if the option on the Subscriber is set tofoise. Important: Subscriber settings are unique to the cluster on which they reside. Sub_New_Moo'uies: If set to true {the default}, then the site automatically receiyes all new modules during a giyen update. The sks.rwc.config file is updated with the appropriate Publisherf'Subscriber options and the new modules are downloaded. f Sub_New_Modules is set tofolse, then it will only update the .ini file with the names of the new modules, but it will not start downloading the new modules. When Sub_New_Modu es is set tofoise, it preyents the Publisher from adding new modules. The names of any modules that will not be added to the Subscriber will be sent yia email to the designated recipientls}. This alerts site administrators of the ayailability of new modules and affords them the opportunity to eyaluate the modules in a safe enyironment before allowing them to be downloaded. or reges: This tells the Publisher that this specific Subscriber does not want updates for specificfiles, eyen if they are part of the latest update. fthe Publisher has a different yersion ofthe file, it will not send the new file. This setting ignores oil changes to the specified files, including files that are slated for remoyal by the Publisher. In fact, under normal configuration, if a file is remoyed on the Publisher, then that file will also be deleted on the Subscriber. Howeyer, ifthe Subscriber is set to ignore changes to that file, then it will not be remoyed. Here, the Subscriber does not want updates to forwarding_whitelist.cfg, appid_authorited.appid or any .tst files in the misc directory.
