LAN Cache

Agent > Configure Agent > LAN Cache

The LAN Cache page designates a machine to act as a file source for other machines on the same LAN. When a LAN cache is enabled and a machine on the same LAN requests a download from the Kaseya Server for the first time, files are downloaded to the LAN cache machine, then copied to the requesting machine. From then on the file does not need to be downloaded from the Kaseya Server. Other machines—on the same LAN and using the same LAN cache—copy the file from the LAN cache machine. Doing so speeds delivery to multiple machines throughout the same LAN and reduces network bandwidth issues.

Background

LAN Cache configures a file source as follows:

• Automatically creates a local administrator or domain administrator account, or allows you to manually specify the credential for an existing domain administrator. Created accounts are given a unique name (FSAdminxxxxxxxxx where x is a digit) with an automatically generated strong password. The generated password contains 15 randomly selected characters and contains at least one the following characters:
  • uppercase letters
  • lowercase letters
  • numbers (0 - 9)
  • non-alphanumeric characters
• Once the password is generated, it is compared against the admin name to ensure that no 2 character combinations in the password match any 2 character combination in the admin name. This logic ensures that the generated passwords will meet any Windows password complexity logic.
• The credentials for the account are associated with this LAN cache within Kaseya and are used when necessary instead of any assigned agent credential. LAN Cache does not require nor support using the credential specified on the Set Credential page.
• Creation of the specified customer share directory on the specified fixed disk drive configured as a Windows administrative share. The directory and share are created for you without leaving the LAN Cache page. The directory specified for LAN cache is strictly for customer use. Kaseya never uses this customer-specified directory/share.
• Creation of a special Kaseya directory—always VSAFileShare as a sub-directory under the customer directory—on the specified fixed disk drive configured as a Windows administrative share.

Procedure - General

1. Select a LAN cache machine.
2. Assign machines to the LAN cache using the Assign LAN Cache page.

Procedure - For writeFile() and getURL() Steps in Agent Procedures

These commands can download files from a LAN Cache instead of the VSA or from a URL. Files have to be larger than 4k bytes.

1. Select a LAN cache machine.
2. Assign machines to the LAN cache using the Assign LAN Cache page.
3. For the writeFile() command only, upload the files you intend to download to assigned machines to the Kaseya Server using Agent Procedures > Manage Procedures > Schedule / Create > Manage Files > Shared folder. Files have to be larger than 4k bytes.
4. Create and run an agent procedure that includes a writeFile() or getURL() step.
   • When an agent executes the writeFile() or getURL() step of an agent procedure for the first time, it downloads the file from the KServer or the URL, then updates the assigned LAN cache with the file.
   • For subsequent requests for the same file by any agent, the file is downloaded from the LAN cache instead of from its original source.
   • To take full advantage of the caching mechanism, execute the agent procedure referencing the file on one agent first. After that agent has uploaded the file to the assigned LAN cache, execute the procedure on other agents assigned to the same LAN cache.

Actions

• Add LAN Cache - Specifies a LAN cache on a selected machine.
  • 1. LAN Cache Name - Enter a name of the LAN cache as it will be displayed in Assign LAN Cache.
  • 2. Directory Name - Enter the name of the directory only, without specifying the name of the machine or the drive letter. The directory does not have to already exist. LAN Cache will create the directory and the required share settings for you.
  • 3. Select the UNC server name resolution - Use Computer Name or Use Computer IP Address. Specifies the UNC name resolution format used to access the share. Example: \\computername\sharename$ or \\10.10.10.118\sharename$.

  Note: The next step—selecting the type of credential—does not display if the System > Default Setting > LAN Cache - Use auto-generated administrator credentials option is set to yes.

  • 4. Select the type of LAN Cache administrator credentials to use
    • Use auto-generated administrator credentials - If selected, an administrator credential is created for you when the LAN Cache is created. A local administrator credential is created unless the machine is a domain controller. If the machine is a domain controller, a domain administrator credential is created.
    • Use an existing domain administrator credential - If selected, enter the domain, username and password of an existing domain credential. The domain credential will not be created for you.
  • 5. Select a fixed drive on which to create the LAN Cache - Select the drive to create the share on.
• Remove LAN Cache - Removes the LAN cache from a selected machine.
• Clear Pending - Cancels the pending creation of a LAN cache on a selected machine.
• Test Generated Cache Credential - Click to test the credentials used by a selected machine. The result is shown in the Credential Test Status column.

• Machine.Group ID - A unique machine ID / group ID / organization ID name for a machine in the VSA.
• Cache Name - The name of the LAN cache as displayed with the VSA.
• Cache Path - The path specified for the LAN cache.
• Cache UNC - The UNC used to locate the LAN cache on the network.
• Cache Created - Date/time the LAN cache was created.
