onedev/server

Same problem as issue onedev/server#512.

Created a new key using ssh-keygen.
Applied Public key to my account at code.onedev.io.
Attempted to Clone the onedev server repo
Error received

You are missing the onedev ssh port in the url. Try below instead:

git clone ssh://code.onedev.io:6611/onedev/server

rhdev commented 2 years ago

@robin - you can see in the response back that the correct port has been used as per what was configured in the SSH config file.

Robin Shen commented 2 years ago

I see you are cloning using below command:

git clone ssh://onedevio/onedev/server

I can clone with below command successfully:

git clone ssh://code.onedev.io:6611/onedev/server

If still not working, please let me know exact command used to generate your SSH keys

Not sure why this is happening. I am testing on Mac and it works fine. What is your OS? Are your public key starts with ssh_rsa?

rhdev commented 2 years ago

@robin Yep. Started with SSH-RSA. I tried again using verbose output:

This gave me a clue - I believe it's not supporting RSA? I recreated using ed25519 algo instead:

$ssh-keygen -t ed25519 -C "your_email@example.com"

I can now clone the server repo:

This is odd. Both rsa and ed25519 key works at my side. What is your OS/version?

Using Arch Linux.

Software and versions: lib32-libssh2 1.10.0-1 libssh 0.9.6-1 libssh2 1.10.0-1 openssh 8.8p1-1 git 2.35.0-1

That link is what drew me to trying ed25519 as a resolution.

Robin Shen commented 2 years ago

Are you able to use your RSA keys to clone via SSH over github?

rhdev commented 2 years ago

Yep, no problems with GitHub.

@rhdev, try to do this command to apply your generated key go git config, and it will work like a charm.

git config --add --local core.sshCommand 'ssh -i <path_to_your_private_key>'

Trevor Sullivan commented 10 months ago

Same problem here with OneDev 8.5.0. I can't use SSH to clone a repository from a local OneDev instance, using my SSH private key. I even tried generating / importing an ed25519 key, and it still fails.

I really want to use self-hosted OneDev, but if I can't even get SSH working, it's a deal breaker. Thanks for the free software though .... it's pretty cool.

Robin Shen commented 10 months ago

Can you please let me know the detailed reproducing steps? This always works at my side (and on many others using OneDev).

Trevor Sullivan commented 10 months ago

I just set up a new Docker container with OneDev, and it's working fine now. I have no idea what was going on before. It was weird.
