sshfs connection reset by peer with Synology NAS

I recently bought a synology NAS (DS216i).

I enabled ssh on it and setup some share. I can successfully ssh into the box but not mount with sshfs.

sshfs user@ip:/volume1 nas

gives me the following error:

read: Connection reset by peer

I've long given up samba and rely on sshfs for sharing stuff. How can I fix this?

For sshfs you need a sftp subsystem enabled, that might not be there by default. First of all, verify that you can connect with command-line sftp. Most probably it will fail the same way so you will have to install a sftp-server to the NAS.

On a DS218j I've had a similar problem. Enabling SSH is not enough.

I'll guess the names for specific options, because my UI is not in English.

There is a "Control Panel" application and in "File Services" > "FTP" scroll down do "SFTP" section, and check the "Enable SFTP service" checkbox, port number: 22.

Now, scp and sftp work fine, and file dates and times are set correclty (unlike when using Samba mounts).

One thing I'm still trying to resolve is mounting it with sshfs - it works for a while and then hangs (maybe after some inactivity period). Bigger transfers with scp seem to work fine, but a mounted subdirectory suddenly becomes empty, e.g. when opening in a file browser.
