tinyssh VS Gravitational Teleport

While on topic of sshd having minimal dependencies, shout-out to Jan Mojžíš and his minimalist implementation:

Yep, same here, except I'm using [tinyssh], which organically does not support anything other than ed25519/curve25519, sha256, and chacha-poly.

[tinyssh] https://tinyssh.org/

djb suggested that for openssh instead of the tinydns kex, so tinydns switched also:

Teleport - Comprehensive control plane tool, but also supports accessing apps behind NATs. Written in Go.

I ordinarily would have said you reinvented Teleport <https://github.com/gravitational/teleport/tree/v14.3.7#readm...> but now that they've gone AGPL with v15 I'm guessing there's a market for MIT licensed stuff, although for sure since Teleport has been around for so long it has encountered more edge cases and undergone more security reviews. I was surprised while digging up the link that Gravatational is still releasing v13 and v14 updates under Apache 2, so maybe even Teleport will continue to have legs for those who cannot deploy AGPL stuff

Teleport is an SSH for Clusters and Teams and aims to be the drop-in replacement for OpenSSH.

Are you looking to set up SSO for your cloud infrastructure? Or maybe establish tunnels to access services behind NATs and firewalls. Then Teleport is for you. It provides connectivity, authentication, access controls and audit for infrastructure. The newest update has a tonne of new features and improvements including enhanced device trust support, SSH connection resumption, MFA for admin actions, improved provisioning for Okta, and heaps. more. Check out all the changes in the Teleport release notes.

In case you didn't see it: https://goteleport.com/blog/teleport-oss-switches-to-agpl-v3... and https://github.com/gravitational/teleport/pull/35259

I readily admit it's not the same amount of :fu: as BuSL or whatever the fuck is going on over at Sentry but still :-( as compared to their much friendlier Apache 2

OP here, thanks for posting! Happy to Answer any questions. I have to give our a shoutout to Alan at Teleport for all his work on Passwordless and his work to make Passwordless / TouchID work with MacOS CLI https://github.com/gravitational/teleport/blob/master/rfd/00...
