ssh.tmate.io not working anymore #257

Open paolomainardi opened 2 years ago

paolomainardi commented 2 years ago

It seems that is not working anymore since some days, what is happening ?

gaetan-puleo commented 2 years ago

On my side It's working but I need to wait a lot of times before I can have a working session.

machty commented 2 years ago

Is ssh.tmate.io down? Who hosts those servers?

rems0 commented 2 years ago

Not working for me either.

candrews67 commented 2 years ago

It is working for me but seems to take an average of 2 minutes to connect

gaetan-puleo commented 2 years ago

it's working again

wekabob commented 2 years ago

No it's not

joellarsonibotta commented 2 years ago

I can confirm that this has been happening to me inconsistently. I never have a problem connecting to port 22, but it's a dice roll if I get connection reset by peer, connection reset by host, or a connection in. I was thinking adding the -o PubkeyAuthentication=no flag was helping but it is too inconsistent for me to be sure.

Note: My usage is with travis-ci but it seems to be an issue with tmate.

Also seeing issues on my end

Juliandev02 commented 2 years ago

image I also can't connect to tmate for about a month.

RamiSiadous commented 2 years ago

It seems that is not working anymore since some days, what is happening ?

cant connect from USA east and west coat

wekabob commented 2 years ago

Gave up and built my own server

gquemener commented 2 years ago

I will most likely move to the same solution.

Hope the maintainer is alright though :thinking: probably gone on holidays :man_shrugging: Enjoy them if this is the case, and thanks for this awesome tool :+1:

nviennot commented 2 years ago

To be honest, I no longer have an interest in maintaining this project and the servers. I'm going to make a shutdown plan in the upcoming weeks.

ELECTROHAXZ commented 2 years ago

To be honest, I no longer have an interest in maintaining this project and the servers. I'm going to make a shutdown plan in the upcoming weeks.

May I ask why? Is it due to server costs? I own a hosting company and may be able to help if so.

nviennot commented 2 years ago

Server cost is one thing, but I don't think I care enough about the project. To continue, I think I would want to make significant changes (remove tmux dependency, use Rust) to make the tool not about pair programming but for remote terminal access. I don't have the time/resources to orient the project in a direction that I want to.

Here's a draft for a new plan: https://docs.google.com/document/d/1pGdKgBj0fr5j_DIi44GiyzqZqXnPRWfQlQqVeXrNrhY/edit?usp=sharing

The idea is to make something lower level, some sort of SSH swiss army tool, that the current tmate could be built upon.

paolomainardi commented 2 years ago

@nicm first of all let me just say THANK YOU so much for this project, we as a company are using tmate since years and it helped us so much back in the days and more amid pandemic.

How we, as a community, can help the project to be auto sustainable ? I don’t think it needs more features, it is just perfect as it is.

gquemener commented 2 years ago

The ease of use of tmate, combined with the flexibility of tmux, makes it a great remote pair programming solution (if not the best when it comes to terminal-based pair programming session). It is particularly suited for mid/low-bandwidth situation where screen sharing is non viable.

I have played around with the tmate server on Google Cloud Compute Engine this afternoon with medium result (some peers were able to connect, some not).

I think having some tutorial to deploy private tmate server on regular cloud providers would be a great benefit to the project and its community (myself included), and could help making it sustainable while having fewer pieces to take care of on your side. I could help with that, however my knowledge is limited.

Let me join paolomainardi in saying thank you 🎉

wekabob commented 2 years ago

Same here with the Thank you.

We have used it for connections during testing, the ability to have Tmux style windows to look at multiple screens at the same time has made our work easier.

If someone is interested in taking over, would you be open to that?

Bob

nviennot commented 2 years ago

I'll think about a plan in the upcoming week

jdoss commented 2 years ago

Hey @nviennot I just reached out via email to see if I can help you with some server space and bandwidth. I love tmate and I use it a lot. I'd hate to see the service go away.

paolomainardi commented 2 years ago

We can sponsor the project too, bandwidth and all the rest.

I too, like others have said, love tmate! I'm not much help at maintaining the project in the way of adding the new features people want but we can provide hosting as well at no cost to you if necessary. We've provide up to 25 Gbps bandwidth and plenty of resources for many connections in our main location, we also own all our own hardware hosted in our privately owned facilities around the world. Let me know if you need anything and hopefully we can help in that regard!

I read the plan you posted as well and personally I like tmate just the way it is, just with the bugs patched. Though I don't really mind more features or changes as long as there are sane defaults, like now.

nviennot commented 2 years ago

That's very generous, thank you, I'll think about it

jungle-boogie commented 2 years ago

Whatever you end up doing, thank you for creating the tool. Lots of people have enjoyed it; even if it’s not perfect or complete in your mind.

Keep up the great job with other software you write.

jmercouris commented 2 years ago

Thank you very much for this project :-)

tenderlove commented 2 years ago

I just wanted to say I love this project. I've been using tmate for years as a pair programming solution. I'm very happy with the project "as-is" and I'd be sad to see it go away. That said, thank you so much for the work on this project it's made my (and also the folks I pair with) life so much easier.

samuelT2 commented 2 years ago

I stumbled across this thread after I wasn't able to reach my clients anymore :) Same here - the tool is just perfect as is. Sad to hear your plans, but understandable. If this project and it's infrastructure could proceed as is, that would be so great. If my help is needed for whatever - ping me.

ingydotnet commented 2 years ago

I just wanted to say I love this project. I've been using tmate for years as a pair programming solution.

I also use it constantly, and probably even paired with @tenderlove using tmate at some point!

I just want to point out that running your own tmate server is trivial. I did for the YAML dev crew. Here's how:

On a public server run:

curl -s -q https://raw.githubusercontent.com/tmate-io/tmate-ssh-server/master/create_keys.sh | bash
docker run \
        -d \
        --name=tmate-server \
        --cap-add SYS_ADMIN \
        -v "$PWD"/keys:/keys \
        -e SSH_KEYS_PATH=/keys \
        -p 12345:12345 \
        -e SSH_PORT_LISTEN=12345 \
        -e SSH_HOSTNAME=tmate.yaml.io \
        -e USE_PROXY_PROTOCOL=0 \
        tmate/tmate-ssh-server:prod

Then users can alias tmate like so:

alias tmate='\tmate -f <(
echo set -g tmate-server-host tmate.yaml.io
echo set -g tmate-server-port 12345
echo set -g tmate-server-rsa-fingerprint SHA256:80bgrhZV4v7Vazw0hxLdkciNFlyAGOYKT8i/H4scsJI
echo set -g tmate-server-ed25519-fingerprint SHA256:ydkiIFYzQsKp6hry2+34bdYumPGxSrOcqbfJZGMLbcs
echo source-file ~/.tmux.conf
)'

That's an actual running tmate server in a docker container on a digitalocean vm. I'll leave it running for a few days. Go ahead an try it out. What could possibly go wrong?!

I know this isn't a perfect solution for replacing ssh.tmate.io but it's better than nothing. I've also used it in work situations behind firewalls where the company didn't trust the tmate.io server.

How did you manage to get that to work? I set up one and tried every combination of things I could to no avail. I made an issue about it here but got no response that I haven't already tried. I tried your server as well and the same exact issue exists on tmate on Debian 10 and 11 using both tmate from apt and the latest tmate binary from tmate.io. It works on Ubuntu but not Debian.

EDIT: It works on some Debian 11 systems and Ubuntu but not Debian 10. Debian 10 repo has version 2.2 and Debian 11 has 2.4, however installing binary 2.4 from tmate.io on Debian 10 does NOT fix the issue. :/ I also don't know why it doesn't work on all Debian 11 systems since it's the same tmate version on both.

ingydotnet commented 2 years ago

@ELECTROHAXZ Yes sorry, I think this only works using the version 2.4 tmate command. In the past I had to run 3 different docker container servers for 2.2, 2.3 and 2.4. I'll try a few things and report back later.

ingydotnet commented 2 years ago

This worked for me on my ubuntu 20.04 host:

> wget https://github.com/tmate-io/tmate/releases/download/2.4.0/tmate-2.4.0-static-linux-amd64.tar.xz
> tar xf tmate-2.4.0-static-linux-amd64.tar.xz
> export PATH=tmate-2.4.0-static-linux-amd64:$PATH
> alias tmate='\tmate -f <(
echo set -g tmate-server-host tmate.yaml.io
echo set -g tmate-server-port 12345
echo set -g tmate-server-rsa-fingerprint SHA256:80bgrhZV4v7Vazw0hxLdkciNFlyAGOYKT8i/H4scsJI
echo set -g tmate-server-ed25519-fingerprint SHA256:ydkiIFYzQsKp6hry2+34bdYumPGxSrOcqbfJZGMLbcs

Yeah I figured it's something with versions. I just don't get why it works on some systems but not others. I tried using version 2.4 and on some systems it works, others (most) do not. How did you run other versions of docker container? Mine seems to only work on 2.4.

paolomainardi commented 2 years ago

@nviennot sorry for chasing, just asking some updates on your side if the current service will be back as it exists now or if it’s better to plan some other strategies on our side to self host the tmate server part.

I think that something like https://opencollective.com/ or Patreon to fund this and the next project would be a way to materialize our help in a better way, at least for the funding part.

nviennot commented 2 years ago

With all these messages, i can't turn off tmate servers, it would be tragic.

I'll restore the service quality this week, and open sponsoring to help keeping it running.

samuelT2 commented 2 years ago

that's probably the best news i'll ready this week...

thank you very much nicolas, much appreciated!

and let us know when a sponser page is setup, i'm ready to help :)

ingydotnet commented 2 years ago

@ELECTROHAXZ

How did you run other versions of docker container? Mine seems to only work on 2.4.

This was a few years ago. The 2.2 server image seems no longer available on https://hub.docker.com/r/tmate/tmate-ssh-server/tags

Darn, that sucks because 2.2 is the newest version available in Debian 10 repos, and Debian 10 is still supported until August at least with security updates for longer.

paolomainardi commented 2 years ago

Today I tested https://upterm.dev/ and it is a very promising alternative to tmate, just in case.

Valcyclovir commented 2 years ago

tmate has been absolutely amazing for my community of 2k+ members helping each other running nodes on our project. It completely removes the trust issues between strangers inside a community and I can't thank you enough to consider ways to help keep the project alive.

DeanIsMe commented 2 years ago

I'm very appreciative that you've decided to keep the servers up!

Has this issue been resolved for others? I'm still getting these messages when trying to start tmate:

Reconnecting...
Connecting to ssh.tmate.io...
Error connecting: Socket error: disconnected
anrahman4 commented 2 years ago

I am also very appreciative of keeping this project alive, it has helped me out in many ways.

I am also still receiving the same issues in starting tmate:

Connecting to ssh.tmate.io... Error connecting: Socket error: disconnected Reconnecting... (Error connecting: Socket error: disconnected) Connecting to ssh.tmate.io...

So the issue does not seem to be resolved as of right now.

MRichards99 commented 2 years ago

It would be great to see this project continue. Myself and my colleagues use the GitHub Action (https://github.com/mxschmitt/action-tmate) to debug failed GitHub Actions runs for our CI. It has been a life saver in several instances, making it much easier to understand the failure and how to fix it.

We hope this project can continue because its genuinely a tool that has helped us save several hours of frustration

arch1mede commented 2 years ago

Agreed, I am very sad that this no longer works.

Valcyclovir commented 2 years ago

seems like upterm is deprecated as well. I found a working alternative for whose still interested. The free tier is 45 minutes sessions. https://duckly.com/

nviennot commented 2 years ago

I'm getting on it, hold tight my friends

nviennot commented 2 years ago

I've added some server capacity. The system should be able to hold up to 25,000 tmate clients. Right now there's 4,000 connections.

jgarte commented 2 years ago

No rush, but will there be a new release made?

arch1mede commented 2 years ago
