tmate-master's Issues

Internationalization of the websockets interface

Hello @nviennot (and all that contribute to the project!),
Thanks for such an amazing project!

We are integrating tmate to the LibreRouter.org, a Mesh Wireless Router that is Free/Libre open source software and hardware, and it is targetted at an international audience.

For now we are using tmate (that itself is in english, but that's fine), and making available the websocket interface through a mobile webapp that is embedded in this routers.

We would like for the strings within the websocket interface (the "session starting", "reconnecting", ...) to be localizable.

I've been checking the possibilities offered by Elixir's Phoenix, and there seems to be a library that enables localization of those strings: https://phrase.com/blog/posts/i18n-for-phoenix-applications-with-gettext/

It could be applied to the rest of the interface... but for us it would be enough to work on the websockets part.

We would contribute with the translation to spanish and portuguese once it comes to be.

thanks!

Hi. How to resolve this:

Hi,

Still trying to setup a working docker-compose configuration. Here is my snippet for tmate-master:

Postgrex.Protocol failed to connect: ** (DBConnection.ConnectionError) tcp connect (tmate-db:5432): timeout

The server was running fine for 2 months before it suddenly stopped working. Whenever I try to run the container, after initializing I get the following error.

tmate-master      | 09:41:22.932 [error] Postgrex.Protocol (#PID<0.2044.0>) failed to connect: ** (DBConnection.ConnectionError) tcp connect (tmate-db:5432): timeout
tmate-master      | 09:41:39.181 [error] Postgrex.Protocol (#PID<0.2045.0>) failed to connect: ** (DBConnection.ConnectionError) tcp connect (tmate-db:5432): timeout
tmate-master      | 09:41:56.813 [error] Postgrex.Protocol (#PID<0.2041.0>) failed to connect: ** (DBConnection.ConnectionError) tcp connect (tmate-db:5432): timeout

These errors come a while after the postgres db is accepting connections, so its not that either. It keeps retrying and failing continuously.

I have tried a lot of things, most of them point to the fact that its the tmate-master container which is unable to make the connection, the db is hosted fine.

The following is my docker-compose.yml Most of it is irrelevant I think, except for tmate-master and PG_URI

If anyone has any ideas as to why the server is failing the connection, please help.

I have tried a lot of changes

• I have tried different versions of postgres for tmate-db. Everything from 11-alpine3.15 to 15. None of them work, all result in the same timeout
• revert docker to an older snap. Same error still
• Run the server from an old instance backup, still same error
• Host a new postgres db on AWS RDS and connect to that instead. I still get the timeout, the server was looking in the right place since I got nxdomain after deleting that server
• Connect to tmate-db through psql on host machine. Connection was made properly without issues
• Ping tmate-db from tmate-master. Ping returned without issues
• change networks on the docker compose. No changes still timed out

I am currently all out of ideas except for forking the original repo and trying to make a build myself. Which would be pretty challenging since I have no experience with Elixer. The project was working fine and suddenly stopped working, so I am very unsure on how to proceed.

Any ideas about even what to look into will be appreciated.

Database migration - Node [email protected] is not running!

Hi,

I'm trying to run database migration as instructed at #1 (comment). But it fails at lauching an elixir shell:

$ docker exec -it tmate-master bash
bash-4.4$ bin/tmate remote_console
Node [email protected] is not running!

The master instance's logs don't give any clue:

$ docker logs -f tmate-master

Help with master setup

Hello,
First of all thank you for the great job and for making it open source.

I am trying to deploy a self hosted version of tmate-master on Kubernetes and, as for now, I was able to deploy both tmate-websocket-server and tmate-ssh-server, but I really do not find a way to get the tmate-master working. I am getting an error on do_boot:

I suppose it could be related with migrations, but I can be wrong.
In tmate-kube/prod there is a txt file with this content:

# run twice. first time will fail with cannot find migrations
Mix.Task.rerun("ecto.migrate", ["-r", Tmate.Repo, "--migrations-path", "./lib/tmate-0.1.1/priv/repo/migrations"])

When should I call this command?

Unattended database migration

Hi,

I've now fully automated my tmate instance deployment, but for the database migration step. Is there a way to run it unattended in a production environment?

Thanks,
