Error running gh net #45

Open purkhusid opened 2 years ago

purkhusid commented 2 years ago

If I run the following command:

RUST_BACKTRACE=full gh net

I get the following output:

@purkhusid this is indeed a confusing error message. I suspect this happens due to failing gh codespace select GH CLI command. Mind trying to run gh-net with a Codespace name to confirm that?

For instance:

gh net --codespace legomushroom-utils-rs-9qpr7qvcxwqr
komazarari commented 1 year ago

Hi, I face the same issue. In my environment, gh cs select works fine but gh net --codespace xxxx exit with the same error and backtraces.

legomushroom commented 1 year ago

@komazarari @purkhusid the issue mind be is that the Linux will use root user for gh-net (we esalate to root automatically to be able to bind to network interfaces) and gh-net is not authenticated for the root user (to check run sudo gh auth status).

To fix this:

  1. Get your current token. Run gh auth status -t and copy token from the output.
  2. Authenticate root user with the token: echo {TOKEN} | sudo gh auth login --with-token
  3. Try the gh net again.

Sorry for the confusing, we should definitely improve the error message in this case. I will keep this issue open to track the work to be done for that.

Related issue on the GH CLI side: https://github.com/cli/cli/issues/5456

If the above does not work for you for some reason. Try connecting to the Codespace with `ssh`: ```shell $ sudo gh cs ssh ``` We rely on the GH CLI `ssh` tunnel to connect to a Codespace, so if that works, you should also be able to use the `gh-net` just fine.

@legomushroom Thank you for your clear explanation. My environment needed a few additional fixes, but finally, I got them working fine. In my case, I installed gh with linuxbrew, so I need to install the gh-net extension for the root as well.

So I installed the extension for root user as followings, then it worked well. Thank you 😃

Yes, it works now. Another tip to troubleshoot, if needed:

sudo -i as then, after some auth login tricks: 

~# gh auth status

etc.
