Using Teleport Connect

Teleport Connect provides easy and secure access to SSH servers, databases, and Kubernetes clusters, with support for other resources coming in the future.

Installation & upgrade

Head over to the Downloads page to download the most recent version. Teleport Connect supports macOS, Linux, and Windows.

tar -xf  teleport-connect-14.2.1-linux-*.tar.gz

"Teleport Connect Setup-14.2.1.exe" /S

User interface

The top bar of Teleport Connect consists of:

• The profile selector (the top right), which allows you to switch between profiles on different Teleport clusters as well as log in or out of the clusters.
• The connection list (the top left) showing recent connections, allowing you to seamlessly switch between them.
• The search bar (in the middle), which allows you to search for resources across clusters.
• The cluster selector (to the left of the search bar), which shows up only if you have set up trusted clusters and there are leaf clusters connected to the root cluster. It lets you browse leaf cluster resources. Also, the "Open new terminal" action will bind new terminal tabs to the selected cluster.
• The additional actions menu (to the left of the profile selector), containing options such as opening a config file or creating an access request in an Enterprise cluster.

The status bar at the bottom displays cluster breadcrumbs in the bottom left, indicating which cluster the current tab is bound to, and the Share Feedback button in the bottom right.

Connect My Computer

Connect My Computer makes it possible to add your personal machine to a Teleport cluster in just a couple of clicks.

It is the easiest way to add a computer to the cluster, whether you're exploring the capabilities of Teleport or want your computer to be available in a Teleport-powered home lab.

Connect My Computer sets up a Teleport agent managed completely by Teleport Connect, without having to use the terminal to get the job done and without the need for tools like systemctl to control the lifecycle of the agent.

Prerequisites

• A macOS or Linux device.
• Teleport Connect v14.1+, on the same major version or one version behind the Teleport Proxy Service version. See version compatibility.
• A local Teleport user: you must authenticate using credentials or passwordless login, and not with SSO.
• Permissions to create join tokens (verb create for the token resource).

• Permissions to read and update user objects in the backend (verbs read and update for the user resource).
• Permissions to read, update, and create roles in the backend (verbs read, update, and create for the role resource).

The agent runs as the current system user, not as root. Some features are thus not available, such as logging in as other system users or host user creation.

Setup and usage

To begin the setup, click on the laptop icon in the top left and select "Connect My Computer". The new tab will guide you through an interaction-free setup. Click "Connect" to start the setup.

The setup creates a new role in the cluster which grants access to your device as the current system user. The role is then added to your user object.

Next, the setup downloads a Teleport agent for your platform and runs teleport node configure pointed at the current cluster. Once that is done, Connect My Computer starts the agent and waits for it to show up in the cluster as an SSH node.

After the agent joins the cluster, the tab transitions to showing the status of the agent. From here, you can connect to the node made available by the agent, stop and start the agent, as well as completely remove it. Manually logging out of the cluster will remove the agent as well.

Your computer will be shared while Teleport Connect is open. To stop sharing, close Teleport Connect or stop the agent through the Connect My Computer tab. Sharing will resume on app restart, unless you stop the agent before exiting. The agent stops immediately if Teleport Connect unexpectedly crashes.

Agent maintenance

The version of the agent downloaded by Teleport Connect always matches the version of Teleport Connect. After upgrading Teleport Connect, Connect My Computer is going to automatically attempt to download a matching agent version before launching the agent.

Connect My Computer always stores just a single version of the agent on disk.

Troubleshooting Connect My Computer

Accessing agent logs

After the setup is done, open the Connect My Computer tab and from the three dots menu within the tab choose "Open agent logs directory".

The Connect My Computer icon is not visible in the top bar

The icon is visible only if your setup satisfies the following requirements:

• A macOS or Linux device.
• Teleport Connect v14.1+, on the same major version or one version behind the Teleport Proxy Service version. See version compatibility.
• A local Teleport user: you must authenticate using credentials or passwordless login, and not with SSO.
• Permissions to create join tokens (verb create for the token resource).

The Connect My Computer tab says that the agent is running, but the computer is not visible in the cluster

Click "Connect" in the Connect My Computer tab. If the error message in the new tab says "access denied", it likely means that there's a role assigned to your cluster user which denies access to the Connect My Computer node, either by denying the specific login or access to the node itself through fields like node_labels. To resolve this problem, inspect the role list in the Management section of the Web UI. First, check what roles are assigned to your user object and then inspect each role. Look for a role with broad deny rules.

If the error message mentions a node or a tunnel not being found, it means that while the cluster has a cached view of the agent, the agent did not join the cluster just yet. Wait for a couple of seconds and try connecting to the node again. If the problem persists, check the agent logs.

Connect My Computer does not work after changing system username

The system username that was in use at the time of configuring Connect My Computer is persisted in the Connect My Computer role for the given cluster user. To regain access to the Connect My Computer node, add the new system username under the logins section of the role. The role can be identified by its name following the format connect-my-computer-<name of cluster user>.

Another solution is to restart the setup.

The agent cannot join the cluster and the logs say the token has expired or was not found

In that scenario, the agent emits logs like these when starting up:

INFO [PROC:1]    Joining the cluster with a secure token. pid:54364.1 service/connect.go:460
INFO [AUTH]      Attempting registration via proxy server. auth/register.go:279
ERRO [PROC:1]    Can not join the cluster as node, the token expired or not found. Regenerate the token and try again. pid:54364.1 service/connect.go:106

During the setup, Connect My Computer creates a join token that is valid for up to five minutes. If the logs say that the token has expired, it most likely means that the initial attempt to join the cluster has failed and you started another one after more than five minutes.

To resolve this problem, remove the agent and perform the setup again.

Restarting the setup

Since Teleport nodes are completely stateless, in case of problems with starting the agent or joining the cluster you may attempt to run the setup again. Either click "Retry" if the setup has failed or choose "Remove agent" from the three dots menu within the Connect My Computer tab after the agent was successfully configured.

Preventing user access to Connect My Computer

If you wish to prevent cluster users from using Connect My Computer, make sure they don't have permissions to create new join tokens. This is controlled by the create verb for the token resource. Either deny this permission explicitly or do not grant it in the first place. See Access Controls Reference Documentation for more details. Denying this permission will hide the icon in the top bar.

Users who already set up agents will still be able to manage those agents, even after the denying them permissions to create join tokens. This is to ensure that a malicious admin is not able to make a user set up an agent and then lock the user out of removing the agent.

To instantly revoke access to agents that have already joined the cluster, look for nodes labeled with the teleport.dev/connect-my-computer/owner label and then place locks on those nodes.

tctl nodes ls -v --query='labels["teleport.dev/connect-my-computer/owner"] != ""'
tctl lock --server-id=Node UUID --message="Using Connect My Computer is forbidden"

Connecting to an SSH server

1. Open a tab with cluster resources by clicking on the plus symbol at the right end of the tab bar. You can also press Ctrl/Cmd + T to achieve the same result.
2. Look for the SSH server you want to connect to and click the Connect button to the right.
3. Select or enter the SSH user you wish to log in as and press Enter.

A new tab will open with a shell session on the chosen server.

Alternatively, you can look for the server in the search bar and press Enter to connect to it.

Opening a local terminal

To open a terminal with a local shell session, either select "Open new terminal" from the additional actions menu or press Ctrl/Cmd + Shift + T.

Any tsh command executed within the tab targets the current cluster. Teleport Connect accomplishes this by setting the environment variables TELEPORT_PROXY and TELEPORT_CLUSTER for the session. Additionally, Teleport Connect prepends the PATH/Path environment variable in the session with the directory containing the tsh binary, even if tsh is not globally available.

When using trusted clusters, the cluster selector allows you to determine which cluster the shell session will be bound to. The selected cluster will be reflected in both the tab title and the status bar.

Connecting to a Kubernetes cluster

1. Open a tab with cluster resources by clicking on the plus symbol at the right end of the tab bar. You can also press Ctrl/Cmd + T to achieve the same result.
2. Select the Kubes section.
3. Look for the cluster you wish to connect to and click the Connect button to the right.

Alternatively, you can look for the cluster in the search bar and press Enter to connect to it.

A new local terminal tab will open which is preconfigured with the KUBECONFIG environment variable pointing to a configuration for the specified cluster. Any tools that respect the KUBECONFIG environment variable (kubectl, helm, etc.) will work without additional configuration. To identify the path to this config for use in other tools, inspect the value of the KUBECONFIG environment variable.

The value of the KUBECONFIG environment variable will persist between app restarts, but this configuration file will not be available or usable when the Kubernetes cluster is removed from the connection list in the top left, or when Teleport Connect is closed.

Connecting to a database

1. Open a tab with cluster resources by clicking on the plus symbol at the end of the tab bar. You can also press Ctrl/Cmd + T to achieve the same result.
2. Select the Databases section.
3. Look for the database server you wish to connect to and click the Connect button to the right.
4. Select or enter the database user you wish to use and press Enter.

A new tab will open with a new connection established between your device and the database server.

Alternatively, you can look for the database in the search bar and press Enter to connect to it.

This connection will remain active until you click the Close Connection button or close Teleport Connect. The port number will persist between app restarts—you can set up your favorite client without worrying about the port suddenly changing.

With a GUI client

To connect with a GUI client, follow the instructions in the database connection tab under the Connect with GUI section.

With a CLI client

The database connection tab shows the command that can be used to connect to the database. You can modify the database name of the connection and then click the Run button to open a new terminal tab with that command executed.

Connecting to multiple clusters

Teleport Connect allows you to log in to multiple clusters at the same time. After logging in to your first cluster, open the profile selector at the top right and click the +Add another cluster button. You can switch between active profiles in multiple ways:

1. Click at the profile selector button at the top right.
2. Open the profile selector with a shortcut (Ctrl/Cmd + I).
3. Select a connection from the connection list at the top to automatically switch to the right profile.

At the moment Teleport Connect supports only one user per cluster. To log in as a different user, log out of the cluster first.

Restarting and reconnecting

Before closing, Teleport Connect will remember the tabs that you had open at the end of the session. Next time you open the app, Connect will ask you if you want to reopen those tabs. If you agree, Connect will restore connections to all resources that were active before you closed the app.

When restoring terminal tabs, Teleport Connect doesn't attempt to re-execute commands that were in progress when the app was closed. It will only restore the working directory for those tabs.

Using tsh outside of Teleport Connect

Teleport Connect ships with its own bundled version of tsh. Teleport Connect will always use this version of tsh for any actions performed within the app.

Teleport Connect makes tsh available to use in your terminal of choice as well. Please note that at the moment tsh and Teleport Connect operate on different sets of profiles, as Teleport Connect sets a custom home location through the TELEPORT_HOME environment variable. For example, logging in to a new cluster through tsh will not make that cluster show up in Teleport Connect.

Configuration

Teleport Connect can be configured by editing the app_config.json file, which it creates on first launch. To open the config file, select "Open config file" from the additional actions menu. The file will open in your default editor.

Below is the list of the supported config properties.

Configuring keyboard shortcuts

A valid shortcut contains at least one modifier and a single key code, for example Shift+Tab. Function keys such as F1 do not require a modifier. Modifiers and a key code must be combined by the + character.

Available modifiers:

• Control, Option, Shift, Command on macOS.
• Ctrl, Alt, Shift on Windows and Linux.

Available key codes:

• 0 to 9
• A to Z
• F1 to F24
• ,, ., /, \, `, -, =, ;, ', [, ]
• Space, Tab, CapsLock, NumLock, ScrollLock, Backspace, Delete, Insert, Enter, Up, Down, Left, Right, Home, End, PageUp, PageDown, Escape, IntlBackslash

Telemetry

When you first start the app, Teleport Connect asks for permission to collect and send telemetry data. This includes tracking events such as:

• Logging in to a cluster
• Starting an SSH, database, or Kubernetes session
• File transfer during an SSH session
• Creating an Access Request
• Reviewing an Access Request
• Assuming an Access Request

On login, we also collect some device-related data:

• Operating system and its version
• App version
• Processor architecture

Additionally, we ask for a job role (answer is optional).

The full list of events and collected data is defined as protocol buffer messages in the Teleport source. We do not track the details of those events but merely that the given event took place. Each event includes the cluster name and user name anonymized with HMAC using the cluster's internal random UUID as the key. It is infeasible to associate this back to a specific cluster or user without access to the cluster's internal datastore.

Disabling telemetry

If you initially agreed to share telemetry data, but now want to opt out, you need to set usageReporting.enabled in the config to false (see Configuration):

"usageReporting.enabled": false

The changes will take effect at the next launch.

Troubleshooting

Resetting the app state might help with UI crashes caused by Teleport Connect getting into an abnormal state. This might happen after downgrading Teleport Connect or performing substantial server-side changes. Those UI crashes typically manifest as a blank window or an Internal Error alert.

To reset the state related to a particular cluster:

1. Log out of the cluster.
2. Close Teleport Connect.
3. Open Teleport Connect, then log back in to the cluster.

To completely wipe all app state:

1. Close Teleport Connect.
2. Remove the internal tsh folder and the app_state.json file to log out of all clusters and clear all remembered tabs and connections.

rm -rf ~/Library/Application\ Support/Teleport\ Connect/{tsh,app_state.json}

rm -rf ~/.config/Teleport\ Connect/{tsh,app_state.json}

rmdir /s /q C:\Users\%UserName%\AppData\Roaming\"Teleport Connect"\tsh
del C:\Users\%UserName%\AppData\Roaming\"Teleport Connect"\app_state.json

Submitting an issue

To submit an issue, click the Submit Feedback button at the bottom right (the speech bubble symbol) and follow the Submit a Bug link.

Using macOS open utility:
open -a "Teleport Connect" --args --connect-debug

Running the executable directly:
/Applications/Teleport\ Connect.app/Contents/MacOS/Teleport\ Connect --connect-debug

teleport-connect --connect-debug

"%LocalAppData%\Programs\teleport-connect\Teleport Connect.exe" --connect-debug

Updating local shell environment

Teleport Connect updates and caches the local shell environment on app restart and not when starting a new shell session. If you add new environment variables to your shell startup files, Connect will see them only after you restart the app.

Skipping TLS certificate verification

You can open Teleport Connect in insecure mode, which skips TLS certificate verification when talking to a Teleport Proxy Service. This is useful in test environments with self-signed certificates or for demo purposes. We do not recommend using this mode in production.

Using macOS open utility:
open -a "Teleport Connect" --args --insecure

Running the executable directly:
/Applications/Teleport\ Connect.app/Contents/MacOS/Teleport\ Connect --insecure

teleport-connect --insecure

"%LocalAppData%\Programs\teleport-connect\Teleport Connect.exe" --insecure

Uninstalling Teleport Connect

sudo rm -rf /Applications/Teleport\ Connect.app

rm -rf ~/Library/Application\ Support/Teleport\ Connect

$ rmdir /s /q "%APPDATA%\Teleport Connect"

sudo apt remove teleport-connect

sudo yum remove teleport-connect
