Teleport FAQ	Frequently Asked Questions About Using Teleport	Teleport FAQ

This page includes answers to frequently asked questions about setting up, managing, and using Teleport. If you are new to Teleport, read our Getting Started Guide.

Can I use Teleport in production today?

Teleport has been deployed on server clusters with thousands of hosts at Fortune 500 companies. It has been through several security audits from nationally recognized technology security companies, so we are comfortable with the stability of Teleport from a security perspective.

Can I connect to nodes behind a firewall?

Yes, Teleport supports reverse SSH tunnels out of the box. To configure behind-firewall clusters, see Configure Trusted Clusters.

How is Teleport's Community Edition different from Enterprise?

Teleport provides two editions:

• Teleport Enterprise
• Teleport Community Edition

Here is a detailed breakdown of the differences between Teleport's editions.

(!docs/pages/includes/edition-comparison.mdx!)

Should we use Teleport Enterprise or Teleport Community Edition for connecting resources to our Teleport cluster?

(!docs/pages/includes/ent-vs-community-faq.mdx!)

Can individual agents create reverse tunnels to the Proxy Service without creating a new cluster?

Yes. When running a Teleport Agent, use the --auth-server flag to point to the Proxy Service address (this would be public_addr and web_listen_addr in your file configuration). For more information, see Adding Nodes to the Cluster.

Can Nodes use a single port for reverse tunnels?

Yes, Teleport supports tunnel multiplexing on a single port. Set the tunnel_listen_addr to use the same port as the web_listen_addr address setting in the proxy_service configuration. Teleport will automatically use multiplexing with that configuration.

Can Teleport be deployed in agentless mode?

Yes. All Teleport services support agentless mode, where the service proxies traffic to an upstream infrastructure resource not available on localhost.

With Teleport in agentless mode, you can easily control access to SSH servers, Kubernetes clusters, desktops, databases, and internal applications without running any additional software on your servers. Agentless mode supports session recordings and audit logs for deep understanding into user behavior.

For capabilities such as kernel-level logging and user provisioning, we recommend Teleport as a drop in replacement for OpenSSH. Since Teleport replaces the OpenSSH agent while preserving OpenSSH's functionality, you get more functionality without a net addition of an agent on your system.

Can I use OpenSSH with a Teleport cluster?

Yes, this question comes up often and is related to the previous one. Take a look at Using OpenSSH Guide.

Can I copy files from one Teleport node to another?

Yes, Teleport supports Headless WebAuthn authentication, which allows you to perform operations like tsh ssh or tsh scp from remote systems where you are not logged in to Teleport or may not have access to a browser.

tsh is very slow on Windows, what to do?

If your host machine is joined to an Active Directory domain, you might find user lookups take a lot longer than you expect. The number of Active Directory accounts that must be scanned to perform a user lookup can cause tsh to hang waiting to get information about the current user. To fix this issue, you can use environment variables to set default account information for your Teleport user. If you are experiencing long lookup times on Windows, do the following:

• Either set the TELEPORT_USER environment variable or set the --user flag to the name of your Teleport user.
• Either set the TELEPORT_LOGIN environment variable or set the --login flag to the name of current host user. This setting can be overridden if you open a new SSH session on a machine as a different user.
• Set the TELEPORT_HOME environment variable to be the home directory of your current host user + \.tsh. For example, if your home directory is C:\Users\Me, you'd set TELEPORT_HOME to C:\Users\Me\.tsh.

You can set these environment variables globally in Windows so that you don't have to set them every time you run tsh.

Which version of Teleport is supported?

Teleport releases a new major version approximately every 4 months, and provides security-critical support for the current and two previous major versions. With our typical release cadence, we usually support each major version for 12 months.

Supported versions

Here are the major versions of Teleport and their support windows:

Release	Release Date	EOL	Minimum tsh version
v17.0	November 16, 2024	November 2025	v16.0.0
v16.0	June 14, 2024	June 2025	v15.0.0
v15.0	January 29, 2024	January 2025	v14.0.0

Version compatibility

(!docs/pages/includes/compatibility.mdx!)

Does the Web UI support copy and paste?

Yes. You can copy and paste using a mouse.

What TCP ports does Teleport use?

Please refer to our Networking guide.

Does Teleport support authentication via OIDC, SAML, or Active Directory?

Teleport offers this feature for the Enterprise (Cloud) and Enterprise (Self-Hosted) versions of Teleport.

Why do changes to a user's role set only take effect on the log next login?

A Teleport user's assigned roles are embedded in the client certificate they receive upon logging on. This certificate remains valid and can be used until its expiry, even if the user's role set has changed.

To get a new certificate with the new role set, the user will need to log out and log back in.

Revocation of Teleport access should be done with Teleport's session and identity locks, not by removing roles.

Does Teleport support provisioning users via SCIM?

Teleport supports SCIM provisioning for Okta via the hosted Okta integration, available in the Enterprise (Cloud) and Enterprise (Self-Hosted) versions of Teleport.

Refer to the hosted Okta integration guide for details on setting up and configuring SCIM support.

Why do I see an alert that some agents are out of date?

Teleport monitors the inventory of all cluster components and compares their Teleport versions with the latest release on our GitHub page. If a component is not on the latest release, Teleport will create a cluster alert encouraging users to upgrade.

This check is performed against all cluster components, including the Proxy Service and Auth Service, as well as agents running other Teleport Services.

What is the minimum TLS version that Teleport requires?

Teleport requires a minimum of TLS version 1.2.

This means that when applications and clients establish or accept TLS connections with Teleport processes, they must use TLS 1.2 or a higher protocol version. Teleport enforces this requirement in all operations that involve TLS connections.

Can I suppress warnings about available upgrades?

Yes. The tctl alerts ack command can be used to acknowledge an alert and temporarily prevent it from being displayed to users. To acknowledge an alert, you need its ID. You can get a listing of all alerts and their IDs with the tctl alerts list command.

For detailed information on this family of commands, see the CLI Reference.

Does Teleport send any data back to the cloud?

The open source edition of Teleport does not send any information to our company, and can be used on servers without internet access.

The commercial editions of Teleport can optionally be configured to send anonymized information, depending on the license purchased. This information contains the following:

• Teleport license identifier;
• anonymized cluster name and Teleport Auth Service host ID;
• for each Teleport user, the anonymized user name and a per-protocol count of interactions - Teleport logins, SSH and Kubernetes exec sessions, Application access web sessions and TCP connections, SSH port forwards, Kubernetes API requests, SFTP actions.

The anonymization is done by passing names and IDs through HMAC-SHA-256, with a HMAC key that's randomly generated when the Teleport cluster is initialized for the first time and is never shared with us; this makes it infeasible for anyone without access to the cluster to deanonymize the data we store.

The code that aggregates and anonymizes this data can be found in our repository on GitHub.

For more details, see the Usage Reporting and Billing guide.

Reach out to sales@goteleport.com if you have questions about the commercial editions of Teleport.
