Known Limitations

1. Legacy Deployment/Deployment Run props vs. new JSON/YAML Deployment Run props Linux’s JSON parsing function, “JQ”, doesn’t allow us to create a variable that makes it easy to call the data within the properties file. It functions in a way that would require us to create a variable for each nested piece of data. 2. You cannot edit Scenarios directly You have to make a new one or clone the one you have in order to change it.
xRDP File Transfer And CAC Passthrough Limitations

xRDP File Transfer And CAC Passthrough Limitations Many users have been switching from VNC to xRDP for a GUI interface connection on linux based machines. xRDP seems to be a little more stable and works better with GPU in particular. However, there are some limitations on xRDP that users have come across: xRDP File Transfer First and foremost is file transfer. Normally for xRDP on Linux this should work just fine, as a mount point will get added to the user’s home directory at /home/<loggedinusername>/thinclient_drives/GUACFS.

Customer FAQs

Question: When a user is sent a link to upload a file to Arcus to his/her email, how long is the link valid? If there is no limit on this, can there be? Example: User A uploads a file. User A then leaves his/her current role and should no longer be able to upload a file. Since this was a link and the user need not be registered in Arcus could he/she keep uploading files indefinitely?

Deployed System Connectivity

Outbound Connectivity Systems deployed into a cloudspace in one of the local Arcus clouds or commercial providers (e.g. AWS GovCloud, Azure, etc.) have the ability to reach out of the enclave to the greater network to access resources. Systems deployed in other DoD cloud providers (e.g. DISA milCloud) are subject to the providers standard rules. Most ports and traffic are allowed, per the latest DoD PPS. If outbound traffic is blocked, submit a support ticket and the request will be reviewed.
vGPU Capabilities

Overview A GPU is a Graphical Processing Unit. It allows computers to better handle graphics-intensive applications, such as web design, video editing, and 3D rendering. A virtual GPU – a vGPU – brings the same functionality to a virtualized system with much greater flexibility in overall capacity and resource availability. Arcus has implemented virtual Graphics Processing Unit (vGPU) capabilities to support those users who require additional resources for graphical- or computational-intensive applications.
