Hi Wes, Thanks for reaching out. I’m one of the mosh maintainrrs, and one of the contributors to that RFC.
To start out with, you should probably reference the latest version of that document, https://datatracker.ietf.org/doc/html/rfc9298. >From there, things get a little complicated. The Github issue you reference started out as a ProxyCommand issue with ssh. This is not something that can be resolved in the mosh codebase alone, as mosh uses UDP and (to my knowledge) there’s no way to create a UDP tunnel over ssh. Leveraging CONNECT-UDP could be done with an outside codebase, such as quic-go (https://quic-go.net/docs/connect-udp/) and having your own proxy tunnel client. Another way to do this would be to modify mosh to natively have a CONNECT-UDP-aware client, rather than using the socket(7) APIs directly. However, this is challenging, as the highest-quality C++ QUIC implementation, Google QUICHE ( https://github.com/google/quiche) is going to be tough to get packaged with popular linux distributions like Debian due to its pervasive use of Bazel. In general, I have aspirations to make mosh move over to QUIC or H3 entirely, but that’s a far-away project. In an ideal world, this would be merged with SSH-over-H3 efforts, such as https://github.com/francoismichel/ssh3 What aspects of CONNECT-UDP are you interested in supporting, here? I see from your email that you’re affiliated with Pomerium — is it fair to assume you’re hoping to support a zero-trust proxy for mosh?
