Can't connect through hop

[estebanviera]

So I currently have my .ssh config set up like this:

Host jumpbox
  MACs hmac-sha2-512-etm@openssh.com
  HostKeyAlgorithms ecdsa-sha2-nistp256
  HostName [REDACTED (jumpbox ip)]
  User [REDACTED]

Host vm1
  RequestTTY force
  HostKeyAlgorithms ecdsa-sha2-nistp256
  HostName [REDACTED (vm1 ip)]
  User [REDACTED]
  ProxyCommand ssh.exe -W %h:%p jumpbox-dallas

so I can connect directly to vm1 using the command ssh vm1 on any terminal.

I'm trying to set up SSH FS to replicate that configuration but I'm having a hard time while doing it. I hope you can help me out :)

This is what I have now:

    "sshfs.configs": [
        {
            "name": "vm1",
            "host": "[REDACTED (vm1 ip)]",
            "hop": "jumpbox",
            "username": "[REDACTED]",
            "password": "[REDACTED]",
            "merge": true,
            "sftpSudo": "apps"
        },
        {
            "name": "jumpbox",
            "host": "[REDACTED (jumpbox ip)]",
            "username": "[REDACTED]",
            "password": "[REDACTED]",
            "merge": true,
            "privateKeyPath": "[REDACTED]"
        }
    ],

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)_

[estebanviera]

Thank you for your answer, I'm attaching the logs:

[INFO]    
Created output channel for vscode-sshfs
When posting your logs somewhere, keep the following in mind:
  - While the logging tries to censor your passwords/passphrases/..., double check!
    Maybe you also want to censor out e.g. the hostname/IP you're connecting to.
  - If you want to report an issue regarding authentication or something else that
    seems to be more of an issue with the actual SSH2 connection, it might be handy
    to reconnect with this added to your User Settings (settings.json) first:
      "sshfs.flags": [ "DEBUG_SSH2" ],
    This will (for new connections) also enable internal SSH2 logging.
