TopoMojo: Building Virtual Labs

This documentation introduces users to the TopoMojo environment and provides information necessary to launch existing labs and create new topologies.

Overview

TopoMojo is a web application used for creating and delivering cybersecurity training labs and exercises. With TopoMojo, users can build and deploy labs in an isolated and secure virtual machine environment.

TopoMojo allows for the same functionality and connectivity that users would experience with real, physical devices. Network topologies can utilize not only IP and Ethernet, but also custom protocol solutions like 802.11 wireless packet simulation.

New topologies can be rapidly deployed using existing templates or built from the ground up with user-provided ISO's and VM specifications.

TopoMojo uses a hypervisor in the back-end to deploy virtual machines and configure virtual networks. Supported hypervisors are VMware vSphere and Proxmox.

TopoMojo Concepts

Workspace and Gamespace

In a workspace, engineers add VMs, save updates, author guides, and configure questions/answers to turn the topology into a lab or challenge.

Users play through a lab in a gamespace. Users get their own, isolated, read-only copies of all resources in the workspace. Players in a gamespace can interact with VMs and answer questions to complete the lab, but they cannot save changes to the environment.

Isolation Tag

The "Isolation Tag" is a unique identifier TopoMojo uses to identify a workspace or gamespace. This ID uniquely identifies each workspace and gamespace in the TopoMojo database.

• For a workspace: the isolation tag is the workspace id visible above the Workspace Title when viewing the workspace.

• For a gamespace: the isolation tag is the gamespace id partially visible from the Admin, Gamespaces view and fully visible in the URL bar when viewing a VM console that belongs to a gamespace.

Each resource (e.g., virtual machine, virtual network, etc.) associated with a workspace or gamespace will have the isolation tag appended to the resource name. For example: a VM named challenge-sever in the gamespace with id (isolation tag) 18048abc66f142e1804732082f4051d2, has the name challenge-server#18048abc66f142e1804732082f4051d2. Appending the isolation tag to workspace/gamespace resources ensures environment isolation and unique resource naming.

Labs and Challenges

A lab or challenge is a TopoMojo workspace built to teach or test hands-on cybersecurity skills. Labs are typically designed to be instructional with detailed documents that might resemble a full walkthrough. Challenges are typically skills assessments with minimal instructions designed to test a user's skills or for use in a competition (e.g., Capture the Flag competition).

Third-party consumers of TopoMojo content, like Gameboard and Moodle, can deploy labs and challenges.

Getting Started

What's New

Get the latest TopoMojo source code and its accompanying release notes from the GitHub repository.

Installing

Install TopoMojo using the Helm chart. The TopoMojo chart contains two sub-charts: topomojo-api and topomojo-ui which you configure and deploy using the main topomojo chart.

Info

This api/ui structure is consistent with the other Crucible apps.

TopoMojo values.yaml: Contains default configurations for the api and the ui. To deploy TopoMojo, configure the Values.yaml file according to your needs then helm install. More details on how to configure the values file is available in the helm charts repository.

Persistent/Shared Networks

We recommend having a persistent/shared network available to all TopoMojo workspaces/gamespaces. The administrator defines a persistent/shared network at the time they deploy the TopoMojo API.

For example, you could create a persistent/shared network that provides internet access to TopoMojo VMs connected to the network named bridge-net.

Use the Pod**Vlan**Reservations environment variable to define the name of a persistent/shared network.

• Pod**Vlan**Reservations**0**Id: defines the vlan Id (from the hypervisor) that corresponds to the shared/persistent network.
• Pod**Vlan**Reservations**0**Name: defines the name of the persistent/shared network.

You can define more than one shared/persistent network by incrementing the variable name (Pod**Vlan**Reservations**1**Id and Pod**Vlan**Reservations**1**Name). To connect VMs to shared/persistent networks, users must have at least Builder permissions.

A note about bridge-net

bridge-net is just an example based on SEI's network naming convention for this persistent/shared network. It is not always configured as a reserved vlan by TopoMojo.

Using a VM Console

TopoMojo provides web-based consoles for interacting with virtual machines using only a modern web browser. The control panel on the left of the VM console offers additional options for using the VM console.

• Settings ( ): Configure behavior/preferences for the console interface.
• Reconnect ( ): Refresh the connection to the VM.
• Keyboard ( ): Send keystrokes to the VM (e.g., ctrl + alt + del).
• Clipboard ( ): Copy/paste with this VM by selecting text to copy out of the VM to your host or paste text from your host to the VM.
• Networks ( ): Change the networks a VM's network interface card is on.
• Screenshot ( ): Take a screenshot of the VM. The screenshot is automatically copied to your host clipboard.
• Record (): Record the VMs screen and save the recording to your computer.
• Fullscreen ( ): Maximize the console's screen.

Finding a Space

You can browse for existing TopoMojo workspaces and gamespaces using the Search field in left panel. Enter search terms then click workspace or gamespace to filter results. The workspace section shows workspaces where you are an editor. The gamespace section shows spaces that you have permission to deploy as a gamespace (more information on permissions)

Select a gamespace, then click Start to "play" the lab -- start by reading the instructions and launching a gamespace resource. You can invite others to play in your gamespace. Click Invite to copy an invitation link for sharing. When you're finished, click End to destroy your gamespace. The timer counts down how much time remains before the gamespace expires.

Users can Favorite a workspace or gamespace using the Star ( ) button next to the title. Favorites appear at the top of the list.

Building a New Workspace

To build a new TopoMojo workspace click New Workspace from the homepage. The workspace interface contains six tabs: Settings, Templates, Document, Challenge, Files, and Play.

Settings

The Settings tab holds configuration metadata for your lab.

Title: The title of your workspace. While not enforced, the title should be unique to prevent confusion when searching for spaces.

Description: A brief description of your workspace to display when browsing titles.

Tags: Space-delimited metadata added to help with searching and cataloging spaces. For example, if working several challenges for the "cyber-cup" project, you may tag a workspace with cyber-cup c01 where cyber-cup is the name of the project and c01 is a challenge number/ID.

Authorship: The names of the challenge authors.

Audience: A space-delimited list of administrator-defined groups that have permission to deploy gamespaces from the workspace. Administrators define an audience with any name here. Users can deploy gamespaces from the workspace only if their scope matches one of the provided audiences. Everyone is the global audience that allows all users to deploy gamespaces from the workspace.

Duration: Recommended length of time, in minutes, that it takes to play through the challenge/lab.

Collaboration: To share your workspace with others, click Generate invitation and send the link to collaborators. TopoMojo shows Collaborators alongside the author. When a collaborator connects to your workspace, you'll see them connected in the top right corner of the workspace.

Clone: Create a copy of your workspace. TopoMojo links the cloned workspace VMs to the parent workspace's VMs. The clone inherits all other settings from the parent. TopoMojo appends -CLONE to the title of the new workspace, but you can change this title.

Delete: Delete the workspace.

Templates

The template selector allows you to add virtual machine templates to your workspace. Templates are "starting point" virtual machines that engineers can add to their workspace and customize as needed.

A typical TopoMojo deployment contains several types of templates.

• Base operating system installs with no software or configurations serve as a known-good starting point for customization.
• Purpose-built templates include preconfigured VMs (e.g., a web server configured to serve content).
• Blank discs let engineers install an operating system not yet available as a template.

Administrators can publish individual templates (e.g., a stand-alone base install of Kali Linux). They can also publish a "template set" of multiple VMs serving as a single "stock topology" (e.g., a full enterprise network with routers, firewalls, services, etc.).

Adding and Editing Templates

To add a template to your workspace:

1. On the Templates tab, click Add Templates.
2. Search for and add the templates you need for your topology.
3. Click the edit icon to expand the template metadata and make changes. Making changes inside the VM requires deploying the VM.

Template Field Definitions

The list below explains the fields in the VM template.

• Name: The name of the VM must be unique within the workspace and should be descriptive of the resource.
• Description: A short description of the VM. It is best practice to include the credentials and purpose for the VM. The description is not visible to users playing the lab - it is only visible in the workspace editor.
• Networks: A space-delimited list of networks on which the VM will have a network interface. These names should be the same for all systems in your lab that need to connect to the same network. TopoMojo creates the networks on the hypervisor when it deploys the VM/lab.
• Guest Settings: Key-value pairs in the form of key=value to pass data into deployed VMs via VMware guestinfo variables or the QEMU Firmware Configuration Device for Proxmox. The key is the name of the guest setting. For example, var1=test is a guest setting named "var1" with a value of "test". You can randomize guest settings values using TopoMojo Transforms.

When using VMware as a backing hypervisor, use VMware Tools, such as the vmtoolsd command from the open-vm-tools package, to access guest info variables from a VM.

When using Proxmox as a backing hypervisor, use the QEMU Firmware Configuration (fw*cfg) Device with commands similar to the following, where variable is the key of the Guest Setting to read: sudo cat /sys/firmware/qemu*fw*cfg/by_name/opt/guestinfo.variable/raw

• Replicas: Set this number to deploy copies of the same VM template. For example: to deploy three copies of a VM template when TopoMojo starts a gamespace, set Replicas to "3". To deploy one copy of the VM template for each member of the team owning the gamespace, set Replicas to "-1".
• Variant: Specify that TopoMojo should deploy the VM template only for a particular variant. For example, if the Variant is "2", TopoMojo deploys the VM template only when it launches variant 2 of the challenge.
• ISO: Use the ISO Selector to attach an ISO image to your virtual machine.
• Console Access: Toggle Hidden to hide a specific VM from view while completing the lab. This is useful for back-end systems like a DHCP server that do not require user interaction or other systems where the user should not have direct console access. Note: These VMs may still be visible/accessible over the network - users just aren't able to click into a console via the lab interface.
• Linked: Unlinking creates a new a new clone of the template which you can save and customize. Unlink any virtual machine that will not use the default disk included with the template (i.e., you need to save changes to the VM).
• Delete Template: Deletes the template from the workspace.

Refresh and Deploy

Once the template is in the appropriate state:

• Refresh ( ): Refresh queries the state of the VM from the hypervisor. This is useful if you run a shutdown command in the VM and the TopoMojo UI icons haven't updated to reflect the powered-off state of the VM yet.
• Deploy ( ): Deploys that virtual machine into your workspace.

Deployed VM Actions

The deployed virtual machine displays the following additional icons from left to right:

• Console ( ): Opens the console for the virtual machine.
• Stop/Start ( / ): Power off/on the VM, but leaves the resource deployed on the hypervisor. Clicking stop results in the hypervisor showing a deployed VM in a powered-off state. Clicking start powers on the deployed VM.
• Revert ( ): Reverts the VM to its last saved state. You lose all changes made since the last commit. TopoMojo can only revert VMs to their last saved state - there is no history of all previous saved states.
• Delete ( ): Deletes a running VM instance. Before you click delete, make sure you have saved any changes to the disk.
• Save ( ): Save any changes made to the VM. Sometimes called "taking a snapshot", though the technical implementation of this feature may not resemble a true "snapshot" on the hypervisor. The save icon is only available when you're using an unlinked disk, since you can't save changes to a linked disk. Clicking save removes the last saved state and creates a new one with all VM changes.

Lab Document

The Document tab in a TopoMojo workspace is where you write the lab instructions using Markdown syntax in TopoMojo's built-in collaborative editor. Authoring in Markdown enables you to create a formatted document using just plain text.

Because TopoMojo's built-in editor is collaborative, multiple people can work on the documentation at the same time. As long as you are "connected" (see the top-right corner) TopoMojo automatically saves your updates to the document.

For more information about Markdown, including the syntax guide, see markdownguide.org.

Inserting an Image

To insert an image into your document:

1. Click Images, then click Browse (you can drag and drop too).
2. After browsing to upload an image, you should see a preview of the image.
3. Place your cursor in the document where you want the image, hover over the image, and click Insert.

Previewing the Doc

To see how your instructions will look to players when they "play" your lab, click the Preview button. The first screen capture shows the Markdown editor. The second screen capture shows the document in preview mode.

Challenge Tab

The Challenge tab in the TopoMojo workspace is where engineers configure randomized challenge configuration (transforms) and questions for the lab/challenge.

Transforms

Transforms allow you to define dynamic variables that TopoMojo generates at gamespace deploy time. Transforms are key/value pairs –- the key is the name of your transform and the value is the type of the transform. Expand the tooltip under the transforms text box to see details about the available transform data types. The screenshot below shows a transform named "token1" that will have a value of 8 random hexadecimal characters.

To access transforms in the challenge, use the referenced "double-pounder-key (##key##)" notation. When TopoMojo deploys a gamespace, the engine generates random values for all transforms, looks for double-pounder-keys, then replaces them with the randomly generated values for that deployment.

Sections on the Challenge tab (e.g., Transforms, Markdown, Questions, Answers) can contain double-pounder-keys that TopoMojo replaces with transform values at deploy time. You can also use transform double-pounder-keys in the Guest Settings field of a template to inject random variables into VM guest info variables when deploying a gamespace. Transforms aren't generated when deploying workspace VMs, so the value of the variable will be the double-pounder-key.

The screenshot below shows the Guest Settings of a VM template configured to use two guest info variables: var1 and token1. Var1 has a value of "test" and token1 will have a random 8-character hexadecimal string assigned when TopoMojo deploys a gamespace.

There is a detailed Guest Settings portion of the Workspace documentation.

Markdown

The markdown you enter here gets appended to the gamespace document at deploy time. This section is useful for appending randomized documentation using transforms to the base lab document authored in the Document section. For example, if a transform randomizes a system's password, you can document the randomly generated password in this section using the double-pounder-key notation for transforms.

Variants

A variant describes a different version of a challenge. Variants can contain different ISO attachments, different virtual machines, and different questions and answers. Each time TopoMojo deploys a challenge, a variant is randomly selected for the deployment. When creating a challenge using variants, make sure all variants test the same competitor skills at the same difficulty level. That is, variant #1 should test the same skills as variant #2 and one variant shouldn't be harder to solve than another variant.

Use the Clone ( ) button to create a new variant that is a copy of an existing variant. This makes minor edits between variants easy to facilitate.

Question Set

Move Up, Move Down, Remove: Use these functions to position the question in the sequence of questions for that set or remove it.

Question: Enter the question you expect the participant to answer here. Your question should be specific, so that there is only one correct answer.

Answer: Enter the correct answer that the competitor must submit to earn a score.

You will see these options when you select Detail ( ).

Hidden: Select Hidden to prevent the question from appearing when playing the challenge. Hidden questions do not appear when playing in TopoMojo or via Gameboard.

Grader: Select the grading type here. The Grader determines if players submitted the correct answer to a question. Select one of four types:

• Match: The submission must exactly match what is in the Answer field. Use this when there is exactly one possible answer to a question.
• MatchAny: The submission must match one of the pipe-delimited answers in the Answer field. Use this when there is more than one possible answer to a question.
• MatchAll: The submission must match all of the pipe-delimited answers in the Answer field. Use this for questions expecting a list of answers.
• MatchAlpha: The submission must exactly match what is in the Answer field after the grader removes all non-alphanumeric characters. This is useful if the user might submit symbols that don't affect the validity of an answer. For example, C:/Users and C:\Users are both valid answers and the symbols (/ vs \) don't matter.

All four grader types are case-insensitive - the grader converts all answers and submissions to lowercase before comparing them to the expected answer.

Weight

Weight is the percentage of the total score for this question. The value should be between 0 and 1 or 0 and 100. The weights of all questions within the set must add up to 100% or one (1). TopoMojo calculates zero (0) values evenly.

Example

Providing an example answer helps players understand the required answer format. For instance, sometimes a file needs both the name and the extension, while other times only the name is necessary.

Files

The Files tab in the TopoMojo workspace allows you to upload files from your system to TopoMojo to include in your lab. You can use these files as ISOs to attach to VMs in the workspace. If your files aren't already in an ISO file format, TopoMojo wraps them in an ISO after upload. When a template has an ISO selected, the VM will deploy with the ISO attached to the CD Drive. You can attach an ISO to upload software, datasets, or other resources to the VM.

Note

For ISO uploads to work, TopoMojo needs an NFS (Network File System) datastore presented to the hypervisor.

By default, the Local filter displays only ISOs available to the current workspace. When you upload a local ISO file, TopoMojo creates a folder named by the workspace GUID--highlighted in green below--in the NFS datastore. Only the current workspace has access to local ISO files in the workspace-named folder.

When you remove the Local filter, you see ISOs in the global folder on the NFS data store. TopoMojo names the global folder with a GUID of all zeros. These global ISOs are available to every workspace in TopoMojo. Use them for commonly reused ISOs, like operating system installers, to prevent re-uploading the same artifact in multiple workspace folders.

You can attach an ISO to a VM in the challenge workspace Templates tab. See the Adding and editing templates section of this guide. When you select an ISO here, TopoMojo attaches the ISO to the VM upon its deployment.

You can also attach an ISO to a VM using the workspace Challenge tab's Variant Detail function. This "dynamic ISO attachment" gives you the ability to attach a variant-specific ISO file to a template. You must specify a target(s) here. See the Variants section of this guide.

Play

The Play tab is where you can interact with your lab in the same way others will when they launch your content or "play" through your challenge. Play deploys a gamespace, a read-only copy of all virtual machines in the workspace. See more about gamespaces in the Workspace and Gamespace section.

Variant: Specify which variant of the challenge you wish to play (if it is a variant challenge). Variant 0 will deploy a random variant.

Max Attempts: The maximum number of submission attempts allowed when answering questions.

Max Minutes: The maximum number of minutes permitted to play before the gamespace expires.

Point Value: Suggested number of points earned for successfully answering all questions. Consumers (e.g., Gameboard and Moodle) can request any point value when they deploy a gamespace.

Start: Starts the gamespace by deploying virtual machines, displaying the Markdown document, making challenge questions available, and starting the timer for the user that clicked Start.

Reset: Destroys and resets the gamespace.

Administrator Guide

Access the Admin Dashboard by clicking Admin in the top right corner of the navigation bar. You need the admin role assigned to your user to see the Admin navigation option.

Hub Connections

Hub connections informs TopoMojo admins about which users are currently logged into TopoMojo.

Announcement

The Announcement feature allows TopoMojo admins to broadcast important messages to everyone in TopoMojo. Announcements appear in the TopoMojo interface. In the Message field, enter the content of the announcement and click Send.

Janitor

The Janitor service cleans up unused resources (e.g., a workspace VM that has been idle for a long time) in TopoMojo.

Cleanup Report: Provides a log of the Janitor's activity.

Gamespaces Tab

The Gamespaces tab is where admins search for gamespaces. Use the table headers to sort results by ID, time remaining before expiration, and parent workspace. Use filters to show active and inactive gamespaces. By default, the search is for active gamespaces. Green indicates active gamespaces and gray indicates inactive gamespaces. An active gamespace is one where the player can still interact with VMs and answer questions. An inactive gamespace is one the player has completed (answered all questions) or that has expired.

Refresh: Refreshes your search.

Delete Selected: Check the box next to All to select all gamespaces for deletion or check a box next to individual gamespaces to select for deletion.

Gamespaces in the table show the following information:

• Gamespace id (e.g. e9416013)
• Time remaining (if active)
• User who owns the gamespace
• Title of the workspace that the gamespace corresponds to

The screenshot below shows several active and inactive gamespaces (usernames redacted).

View (Expanded)

View: Selecting View expands the gamespace information where a list of all the VMs associated with the gamespace and their state.

• Refresh ( ): Refresh the state of the VM from the hypervisor.
• Console ( ): Opens the console for the virtual machine, allowing interaction.
• Stop/Start ( / ): Power off/on the VM, but leaves the resource deployed on the hypervisor. Clicking stop results in the hypervisor showing a deployed VM in a powered-off state. Clicking start powers on the deployed VM.
• Revert ( ): Reverts the VM to its last saved state.
• Delete ( ): Deletes a running VM instance.
• JSON ( ): Shows detailed information about the gamespace, including: answers to questions, variables associated with the challenge, submitted answers, challenge questions and expected answers, and if the participant answered questions correctly or incorrectly.
• Dispatcher ( ) : Used to issue commands to a VM from TopoMojo provided that the TopoMojo agent program is running on that VM. The VM requires an internet connection which allows the agent program to establish a connection with TopoMojo. target is the hostname of the VM that you want to run the command on. command is any command you wish to run. See TopoMojo's GitHub repository for more information on TopoMojo's agent.

Delete

Delete ( ): Deletes the gamespace and associated VMs. This deletes the full gamespace record from TopoMojo's database.

Workspaces Tab

The Workspaces tab is where the admin can search for workspaces. Use the table headers to sort results by title, created date, and last activity.

An admin can view every workspace using this menu, even without being a collaborator. Admins and non-admins use the search feature in the left navigation pane to view workspaces where they are a collaborator. See Finding a Space for more details.

• Create ( ): Create a new workspace from the Admin Workspaces panel. For additional help, see Building a new workspace.
• Upload Zip ( ): Upload a workspace export zip to import workspaces into TopoMojo.
• Download ( ): Download a zipped workspace export. Workspace exports can contain one or more workspaces. TopoMojo will automatically include additional dependent workspaces and templates for workspaces that contain linked resources.

Selecting a workspace takes you the Settings tab of that workspace. For additional help on the Settings tab, see Building a new workspace.

The workspace id is visible below the workspace title. The workspace identifier matches the directory name used to track the workspace in the database, store files on the file system, and track associated VMs. Click the ID to copy it to your clipboard.

View (Expanded)

Template Limit: Defines the number of VM templates you can add to the workspace.

Template Scope: Limits a workspace to using templates that have the given scope.

Audience: Limits who can deploy a gamespace as a workspace.

VMs: Refresh, deploy, view the console, start/stop, revert and delete from here. Functions are the same as previously described.

Templates Tab

The Templates tab is where you can view all of the templates that exist in TopoMojo.

Search: Search for templates by workspace or name. You can apply filters to narrow your search. In the screenshot below, the filter is for linked VMs with a parent template of kali-201901.

Filter for all templates from a workspace by clicking the name of the of the workspace in the list.

Linked and unlinked templates

The chain link icon ( ) next to a template name indicates the VM is linked. Use linked VMs when the prebuilt, stock templates included with TopoMojo meet your needs. Linked VMs save resources when VMs don't require custom configurations when deployed. Changes can't be saved to linked VMs when deployed. Changes can only be saved to unlinked VMs.

Unlinked VMs are marked with the unlinked icon ( ) and show the parent template name.

Template Properties

See Template Field Definitions for details on template configuration.

Machines Tab

This tab lists VMs TopoMojo is tracking for all workspaces and gamespaces.

• gamespace indicates this VM belongs to a gamespace.
• pc5-ubuntu-server-2204-594 is the name of the VM.
• #d9b090c92728424781537c66b3ee2f4b is the gamespace GUID appended to the VM name for ease of tracking.

"Orphaned" VMs

VMs tagged with **orphaned are VMs that still exist but are not associated with a workspace or gamespace. VMs can become orphaned when there is an error or disconnection from the hypervisor during TopoMojo's cleanup process. Orphaned VMs should be manually removed from the hypervisor.

To quickly identify orphaned VMs, search for "orphaned" in the Search field.

Users Tab

The Users tab shows all TopoMojo users. You can create new users and assign users permissions here. To search for a user, enter the term into the Search field or filter by role or audience. Recall from workspace Settings that audience is a list of clients who can launch the workspace as a gamespace.

• View ( ): Select View to see the properties for the user.
• Delete ( ): Deletes the user.

Roles

• User: No extra permissions in TopoMojo. This is the TopoMojo default.
• Builder: Can connect to reserved networks such as bridge-net.
• Creator: Same permissions as builder with additional permissions to bypass building limits such as the number of owned workspaces and workspace template limits.
• Observer: Allows a user to view and use the Observe tab for viewing gamespaces. The scope of the user (see below) limits access to gamespaces with a matching audience.
• Admin: Full administrative access to TopoMojo.
• Disabled: No permissions in TopoMojo.

Grant the Creator role to users who need to build workspaces and troubleshoot deployed gamespaces.

An administrator can configure TopoMojo to inherit user roles from the Identity Provider (IdP). For example, an IdP administrator can add roles like administrator, builder, or a custom role then configure TopoMojo to map those IdP roles to TopoMojo roles. Inheriting roles reduces the need for redundant setup if you're already managing user roles on the identity provider across multiple Crucible apps. See the Helm deployment documentation for more information on how to configure this setting.

Create a New User

• Name: Enter a new user name here.
• Scope: A space-delimited list of administrator-defined groups the user belongs to. Administrators can define a scope with any name here. A user's scope determines which workspaces they have permission to deploy gamespaces from. Users can only deploy a gamespace from a workspace if the user has a scope that matches an audience defined in the workspace. See also: Building a new workspace.
• Workspace Limit: The maximum number of workspaces this user can manage.
• Gamespace Limit: The maximum number of concurrent active gamespaces allowed for this user.
• Gamespace Max Duration: The maximum amount of minutes allowed for a gamespace.
• Gamespace Cleanup Grace time: The number of minutes between gamespace expiration and when TopoMojo tears down the associated VMs.
• Generate ApiKey: Generate API keys for users to programmatically interact with the TopoMojo API without needing to log in interactively.

Settings Tab

Upload a custom background image to change TopoMojo's theme.

Log Tab

The Log tab is useful from the admin point of view when trying to troubleshoot. The Log tab only shows errors here, not every log line.
