Configuring A Server

Administrators (users with superuser privileges) can configure the JetStream server referred to by a Location. To bring up the Server Configration dialog:

  • Select Locations ‣ Location Manager from the menu.
  • In the Location Manager, double-click anywhere along the row of the location you would like to edit.
  • Press the Configure server… button.

Clicking Save will immediately commit the settings to the JetStream server.

Configuring A Server

License

Indicates if the server is licensed. Only licensed servers can send or receive file transfers. The license key can be set or changed by clicking on the Set License Key button.

Clicking Submit… will immediately set the license.

If the Validate license option is on, then the server will check that the license is valid before committing it to the server. If the license is not valid, then no changes are made on Submit.

Bandwidth

JetStream servers can be set up with incoming and outgoing bandwidth limits, to control the total bandwidth the server can consume.

In addition to setting an incoming or outgoing limit, a policy can be set up to borrow (or share) unused bandwidth between the two limits. Enabling borrowing would allow for maximum utilization of the bandwidth allocated to the JetStream server.

For example, a server is allocated 500Mbit/s total, of which 200Mbit/s is used for incoming bandwidth, and 300Mbit/s for outgoing bandwidth limits. By enabling incoming bandwidth borrowing, outgoing transfers will be able to consume the full 500Mbit/s when there are no incoming transfers. If a new incoming transfer arrives, the incoming bandwidth would be automatically reallocated to the incoming transfer.

Sandbox Mappings

JetStream servers can restrict a user’s activity to a specific location in the file system, or sandbox. Sandboxes can be used to isolate users, or limit them to only specific resources.

There are 2 levels of sandboxing:

  • All users: the sandbox mapping applies to every user unless that user has its own mapping.
  • Specific user: the sandbox mapping only applies to this user.

A user can have any number of sandboxes so long as these sandboxes have unique names. A sandbox without a name shows up as the root drive /.

A sandbox mapping can be added by clicking the Add Sandbox Mapping button.

There are 3 types of sandbox:

  • File Path: Restricts a user to a specific folder accessible to the server.
  • S3 Bucket: Restricts a user to a specific folder in an AWS S3 bucket. This type of sandbox requires S3 credentials.
  • Net Share: Windows only When sandboxing to an SMB share on Windows (e.g. //machine/share) where the user does not have credentials to that SMB share, use this type of sandbox to specify the SMB credentials. If the user’s regular credentials are adequate, then use a File Path mapping instead.
