Error: Failure

The failure error message comes from the remote side and is more or less the default/generic error message that sftp server sends when a syscall fails or something similar happens. To know what exactly is going wrong you could try to enable debug output for the sftp server and then execute your transfers again and see what (if anything) shows up in the logs there.

Error: Failure - Solution One

Change remotePath to the actual path if it's a symlink.

Error: Failure - Solution Two

The problem could be that your server runs out of file descriptors. You should try to increase the file descriptors limit. If you don't have the permission to do this, set limitOpenFilesOnRemote option in your config.

Error: Connection closed

The problem could be that the SFTP extension keeps closing the connection for those who use more legacy/old systems. You'll have to Explicitly override the default transport layer algorithms used for the connection to remove the new "diffie-hellman-group-exchange-sha256" algorithm that cause the problem from the kex section. Just add this in your sftp.json configuration file, which should make it work.

Error: Clicking Upload Changed Files does not work

See vscode-sftp issue #854.

@PaPa31 added a fix to make the 'Upload Changed Files' command visible and added a default keyboard shortcut to call it.

ENFILE: file table overflow ...

MacOS have a harsh limit on number of open files.

ENFILE: file table overflow ... - Solution for MacOS harsh limit

Run those command:

echo kern.maxfiles=65536 | sudo tee -a /etc/sysctl.conf
echo kern.maxfilesperproc=65536 | sudo tee -a /etc/sysctl.conf
sudo sysctl -w kern.maxfiles=65536
sudo sysctl -w kern.maxfilesperproc=65536
ulimit -n 65536

How do I upload content inside a folder, but not the folder itself?

See vscode-sftp issue #852.

As quoted from raoul2000, "as long as you set the context property to ./[path] (e.g., ./build), it will work."

Example configuration (where all JS and HTML files in ./build will be copied to /folder1/folder2/folder3):

{
  "name": "My Server",
  "host": "<host_ip_address>",
  "protocol": "sftp",
  "port": 22,
  "username": "user1",
  "remotePath": "/folder1/folder2/folder3",
  "context": "./build",
  "uploadOnSave": false,
  "watcher": {
    "files": "*.{js,html}",
    "autoUpload": true,
    "autoDelete": false
  }
}

How can I upload files as root?

See vscode-sftp issue #559.

Yevhen-development has a workaround, but it may not work for everyone. In sftp.json, set the following:

"sshCustomParams": "sudo su -;"

Automatically sync both ways without user interaction

See vscode-sftp issue #136.

This can also be used with GIT this way when you're checking out a branch or reverting changes/commits, your server will also be updated.

{
  "name": "My Server",
  "host": "<host_ip_address>",
  "protocol": "sftp",
  "port": 22,
  "username": "user1",
  "remotePath": "/folder1/folder2/folder3",
  "uploadOnSave": false, // Set to false if watcher `autoUpload` is set to true & `files` is set to "**/*".
  "watcher": {
    "files": "**/*",
    "autoUpload": true,
    "autoDelete": true
  }
  "syncOption": {
    "delete": true // Delete extraneous files from destination directories.
  },
}

Show dotfiles/hidden files in remote explorer

If using proftpd

Please edit the config file proftpd.conf. Depending on your installation, the default location for this file can be one of those :

  • /etc/proftpd.conf
  • /etc/proftpd/proftpd.conf
  • /usr/local/etc/proftpd.conf
  • /usr/local/etc/proftpd/proftpd.conf

Search for the ListOptions parameter and change it from "-l" to "-la".

It should look like this :

#Global settings
<Global>
[...]
ListOptions 		"-la"
[...]
</Global>
