Localhost.run - not getting the Sub-domain name from the log

[iosoft]

Hello,

I am using the Localhost.run service because its free. Here is my configuration -

hostname: localhost.run
ssh_port: 22
username: autossh
remote_forwarding:
  - localhost.run:80:192.168.79.79:8123
other_ssh_options: '-v'
force_keygen: false

Even though the connection works, but, I can not find the subdomain name from the log details.

As you can see, I can't get the subdomain name! The log ends there.....

Hey, cool service.

I get your point but how do we best solve this? Where would you normally expect this subdomain name and do you have any clue how to read it?

[ThomDietrich]

So here is the thing. We use autossh to connect the tunnel. Any of the parameters probably hides the line you are missing. My suggestion is you install autossh, copy the command from the script, then try around to understand which command line argument is the culprit. Happy to help fixing the issue if you figure out what it is ;)

Here is the command: https://github.com/ThomDietrich/home-assistant-addons/blob/aeb2187a0cd783c660a23b7e96c769231673b30f/autossh/run.sh#L73-L81

[ThomDietrich]

Anything you wanna add?

[iosoft]

Hello, I am back.

How can I test the command by removing the -N argument?

[ThomDietrich]

You don't have to test this from the Home Assistant host. Just try on your local machine. Alternatively there is a Terminal addon for home assistant, you could try with that. The goal is to play around with autossh

[iosoft]

Hi, I was just going to inform you that - Connection successful if -N argument is removed!

Executing command: /usr/bin/autossh -M 0 -o ServerAliveInterval=30 -o ServerAliveCountMax=3 -o StrictHostKeyChecking=no -o ExitOnForwardFailure=yes -p 22 -t -t -i /data/ssh_keys/autossh_rsa_key autossh@localhost.run -R 80:192.168.79.79:8123 -v

I would like to request you to update your awesome and important plugin and move the -N argument as a toggle thing in configuration page or in 'other_ssh_options' text field.

P.S. In you documentation/manual, pls do mention that the 'remote_forwarding' should be like this - 80:HomeAssistantIP:8123

Thanks.

Not sure about your suggestion, why is this not correct? https://github.com/ThomDietrich/home-assistant-addons/blob/master/autossh/DOCS.md#option-remote_forwarding=

[ThomDietrich]

Done in version 1.0.9 👍

[ThomDietrich]

Ah one more thing: It would be cool if you drafted a small passage for the README how this can be used with localhost.run. Please be subjective and mention potential risks or limitations...

[iosoft]

Sure, I will help you.

I stopped using localhost.run service as technically its useless. The temporary URL changes after random time interval.
