[mikev4]

I can access to remote server via terminal , but sshfs

it too slow that I spend about 30s connect to remote server by terminal , I guess it is timeout via sshfs plugin? its there any params can config connection timeout? look likeconnectionTimeout maybe thx for your help

error info

This issue would be easier to solve with debug logs, so please follow these steps:

• Add DEBUG_SSH2 to the sshfs.flags array in VS Code's User Settings (settings.json) e.g. "sshfs.flags": ["DEBUG_SSH2"]
  • See this issue for more information about adding flags
• If you already have a connection open, close it completely (or even reload the window)
• Go to Output > SSH FS and copy the log from there after replicating your bug
• While it should censor passwords/passphrases, I recommend checking it for (other) sensitive data first. (especially since DEBUG_SSH2 activates some internal logging, which is less likely to be censored)

[SchoofsKelvin]

Does it take a long time when you authenticate using ssh or similar, e.g. by not using the extension?

I'll have to check the source code of the ssh2 library in detail to check something, but my first idea looking at your log is that your sshd server seems to not respond to a none authentication request? I'm not sure if you've configured anything regarding this or whether your server is busy querying some authentication data. Perhaps the sshd logs (with a debug log level) might tell you more (bit of a security risk to post those) as to what's happening after it receives the authentication request.

In the meantime, I'll see about creating a build of the extension with none disabled. Pretty sure the ssh2 library can be coerced to skip that.

[SchoofsKelvin]

Could you try out the .vsix from the latest build here? It'll try password > agent > publickey (aka privateKey) > keyboard-interactive > none, in that order, skipping the ones it can't do (e.g. password without a password set). If the issue is with your server mishandling none, this build should fix your issue and give me an idea of how to properly solve it for public release.
