I run screen inside my mosh sessions which provides scrollback, among other features. (Tmux is another option.) ET is also a great solution, but I happen to need screen or something like it for its other features anyway.

I've been using mosh since it was announced, but I periodically try Eternal Terminal.

However I havent ever managed to get ET running on Amazon Linux which all my AWS EC2 instances run. I've tried compiling, docker, app images and nothing has worked.

Just checked this out, and the scrollback feature looks great.

I'd like to try this out, but am I understanding correctly that this needs to be installed on the server side as well as the client? That seems like a fairly large limitation compared to mosh.

Mosh also needs to be installed on the server.

Ah, you're right, I misunderstood. Thanks!

Did they disable the telemetry? Last time I checked, you needed to compile it yourself to get rid of that.

Not a fan of telemetry in secure shell tools.

The first message I get when starting it up:

    Eternal Terminal collects crashes and errors in order to help us improve your experience.
    The data collected is anonymous.
    You can opt-out of telemetry by setting the environment variable ET_NO_TELEMETRY to any non-empty value.
