How do you proxy the SSH connections? I thought you could not do hostname-based proxying with the SSH protocol

It's kind of funny our experiences are so diffent. I almost immediately surmised it's some sort of on the fly generated vm you can access via a ssh jumpserver. Which it is! It's actually really neat. It's quite obvious that the authors want us to just ssh into it and try it out first.

Please complete registration by running: ssh exe.dev Connection to exe.dev closed.
Anyone get a similar issue?

"ssh exe.dev" is exactly the Linux command you would use to connect there via ssh. And it's stylized like command prompt.
This is freaking fantastic. However, as a community college instructor I would like to have this self-hosted on a computer in campus. Excluding the CLI niceties, etc., it shouldn't be to hard to get a similar setup with Docker et al, right? (not for production)
But if you just need a shell then yes, you can make something similar with docker.
Enjoy my creation https://love-storm.exe.xyz:8001
I mean it and I wish the best of luck for the project
That being said, I tried to look at it for asap golang project deployments and I am the creator of https://spocklet-pomodo.hf.space/ a single main.go + single dep multiplayer pomodoro (please note that it was one shotted out of curiosity and also frustration as https://cuckoo.team would sometimes glitch for me)
That being said, I face the issue where I can't have a go.mod or run go mod tidy because I face this error
exedev@crimson-cobra:~$ go mod tidy go: finding module for package github.com/gorilla/websocket go: pomodo imports
github.com/gorilla/websocket: module github.com/gorilla/websocket: Get "https://proxy.golang.org/github.com/gorilla/websocket/@v/lis...": dial tcp: lookup proxy.golang.org on 1.1.1.1:53: read udp 10.42.0.45:33739->1.1.1.1:53: i/o timeout
Hope that the project fixes this and wishing best of luck to the project. I am a little busy right now with studies but your idea truly inspired me and perhaps I want to create a similar thing or collaborate on it with you too so I will join discord hopefully sooner than later.
I am looking further into it and seeing if I can fix that error as I would love to host some exe.dev's services and wishing the best of luck for the project and hope that it becomes sustainable enough.
Out of curiosity, if I may ask, what is the tech stack behind this which generates the vm's. Is it libvirt or firecracker perhaps?
For my own use cases, I recently rediscovered incus and even ran it on cachyos on my desktop to try it out and there were some hiccups partially because I was running it on non standard debian/ubuntu but I am overall very pleasant with incus but still, I am interested in what tech stack you used so please discuss!!
Also what cloud provider are you using. Pro tip but if you are looking for something cheap, either go with ovh or upcloud.
I really really love hetzner a lot too. (Hey hetzner_OL if you are reading this, love hetzner, have a nice day and hope your christmas was good:)
But still hetzner is a little admittedly more strict than ovh but maybe hetzner can respond to it as I know that their policy can ban accounts if someone abuses and considering that you provide compute (to even free) chances of abuse can rise but overall hetzner's the cheapest so I hope hetzner team might make an special exception/response to your post/my comment.
I am imagining a github private action which ssh's into this and then updates and runs a simple shell script which can be a reinstall state every time someone updates something in git to get git-ops style workflow. If someone implements it for exe.dev, just credit me :) (if you so wish) ` An amazing product overall. 7/10 due to that one hiccup which saddened me a bit (but which I have faith can be fixed) but its a 9-10/10 potential and that means a lot and a 7/10 at launch is pretty good
Please just tell me every decision/question I had in depth since I love details about projects like these ^^
Another minor suggestion I can have is having asciinema gif too to showcase what it does for some people. To me I only understood to run the command ssh exe.dev which then helped me learn but the only way I understood what exe.dev does beforehand was reading the comments on HN
An asciinema can go a long way in this journey, perhaps, let me know your thoughts.
And have a nice day! One thing I am wondering tho is if you are gonna open source the project, one project which feels similar to your project which is open source is this https://github.com/ekzhang/ssh-hypervisor that runs on top of firecracker

>Instead of installing a container manager or using Unix users, just make another VM. What is the advantage of this? Unless you need something exotic like different kernel configurations per instance, what's the problem with using containers on the same instance? BTW, a Hetzner dedicated server with 2 CPUs/8GB RAM that would let me run my own hypervisor is about $14 USD/month. For anyone who's a big enough power user…
Containers aren’t enough for me. I like to do things like create TUN devices, run docker compose, etc. I believe the VM is a fundamentally better abstraction. Consider this: sometimes when you are using a VPS, you start a new project and say to yourself, "I should put this on a new VPS." Not all the time, but it does happen. And when it does, we are faced with the problem that starting a new project immediately costs…
Is that possible and useful with exe.dev? The docs say:
On the networking side, we don't give your VM its own public IP. Instead, we terminate HTTPS/TLS requests, and proxy them securely to your VM's web servers. For SSH, we handle ssh vmname.exe.xyz.
> run docker compose
You can run multiple compose stacks in a single VPS.

I never did that.
