Overview

The Data Warehouse Share for SFTP automatically syncs the data in your Funnel account to a server using SSH File Transfer Protocol.

SFTP server settings

Permissions

We need access to write and delete files at the location of the path you have selected, where meta files (summary, schema, test files, etc) will be stored.

Your settings can optionally block all meta files if you want to be strict, except for the test file.

The data files are written to the "file name template" which optionally can include a path, eg data/{startDate}.csv which also needs to be writable.

A test .txt file is stored temporarily using the file name template and is immediately removed if delete access has been granted.

Share setup

Choose what formats, data to share, and schedule you want.

You need to have an SFTP server that can be accessed by external services.
Check with your IT provider that you have:

  • hostname and port

  • username/password created that allows adding files.¬†

  • path to put files under and what filenames to use.

These credentials should be unique to this Share and not allow access to other resources.

NOTE: Funnel's SFTP traffic comes from either of these IP Addresses:

  • 54.81.136.8 - if you are using our app.funnel.io service,

  • 18.193.167.135 - if you are using our app.eu.funnel.io service.

To further increase security you can also require public-key authentication using the key below.

Default - If you are using our app.funnel.io service

Troubleshooting

Below are some error messages that can occur:

  • "getaddrinfo ENOTFOUND" ¬†means that the hostname is not known, check the hostname and that it is a name or IP that is accessible from the internet.

  • "no matching client->server cipher" typically means that the server implementation is old. Our services use most currently preferred ciphers. See below for more on this.

  • "Unable to contact server" typically indicates that Funnel could not connect to the SFTP server. If using IP security in a firewall ensure that AWS can access the server. We are on either us-east-1 or eu-central-1 region and ELB service for now and the current details are on https://docs.aws.amazon.com/general/latest/gr/aws-ip-ranges.html

  • "All configured authentication methods failed" happens when Funnel could reach the server but didn't get access. Validate that you've put in the correct username/password combination and that if your server blocks password only authentication, you have also allowed our public-key

How to check if your server supports Funnel's SFTP sharing

For protocol details, see Protocol support below

To find out if your server supports a certain cipher, you can type this into a terminal window:
sftp -v -c aes128-ctr your.sftp.server

The SFTP server does not support the requested cipher if the response looks like this:

Unable to negotiate with xxx.xxx.xxx.xxx. port 22: no matching cipher found. 
Their offer: twofish256-cbc,twofish-cbc,twofish128-cbc,blowfish-cbc,3des-cbc,arcfour,cast128-cbc,aes256-cbc,aes128-cbc

This will also tell you which ciphers the server does support.
