VSCodium macOS cannot connect using public key #90

Closed Dekker1 closed 1 year ago

Dekker1 commented 1 year ago

I'm using VSCodium on an M1 macOS system. I recently switched from VS Code, and use the MS extension. (I was really grateful to see an open alternative. Thank you for the hard work!) I have various servers to which I connect with SSH using public key authentication, but I cannot get it to work using this extension. When I try to connect I am prompted by the following message.

I don't know which password it is asking for, but when I enter the password for the account on the server I get re-prompted, so I assume this is not the one. My public key does not have a password, but leaving it blank results in an error Could not establish connection to "<server>" and the following messages are displayed in the output.

Am I doing something wrong, or am I trying to use something that isn't supported? (maybe ed25519 keys, or keys without passwords?)

@Dekker1 it supports both ed25519 keys and passwordless keys, and I'm using them both :thinking:. could you try first deleting your key from the ssh-agent with ssh-add -D and then adding it back ssh-add ~/.ssh/id_ed25519 and see if it ask for the passphrase or not

I managed to resolve the issue. I tried your suggestions, using ssh-add I was prompted for a password, but leaving it empty worked. Then I was reminded that this might be because the password was stored somewhere. I found that in my .ssh/config I had set `UseKeychain yes, and the password was stored in the macOS key chain. It seems that the VSCode extension (and the local ssh installation) that I used previously, must have abided by this option and used the system stored password. (It apparently had been so long that I had even forgotten I still had a password).

It would be great if this extension could support the UseKeychain option.

@Dekker1 Just tested this and for me it's working as expected and reading the key from the agent, I forgot to mention you need to pass --apple-use-keychain so the correct command is ssh-add --apple-use-keychain ~/.ssh/id_ed25519, I don't have UseKeychain yes in my config Let me know if it's working after you use the updated command

Great! That fully solves my issue. Thank you for the amazing support!
