Doesn't work for Synology NAS

[Identifier]

Possibly related to #303. On my Synology NAS, even with SFTP enabled, it doesn't have /usr/lib/openssh/sftp-server or even /usr/libexec/sftp-server. In fact, sudo find / -name sftp-server returns nothing at all.

I noticed in /etc/ssh/sshd_config they have:

# override default of no subsystems
#Subsystem  sftp    /usr/libexec/sftp-server
Subsystem       sftp    internal-sftp -f DAEMON -u 000

Is there any way to get this extension working in this case? I tried adding "flags": ["CHECK_HOME=false"] to my settings.json/sshfs.configs for my host, but I couldn't see any difference. Here are the complete logs from the output window:

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.

At this point it just sits there indefinitely...

Try enabling the User Home service and then connect as a non-root user

[Identifier]

It's enabled. My user does have a home folder already.

[luckman212]

are you using passwords or public key auth?

[Identifier]

Was using passwords.

But since then I've switched to keys and also I just switched to vscode's Remote-SSH for everything.
