We’re excited to announce that the Mr.Host FTP servers have been upgraded to support secure encrypted connections, for all Mr.Host web hosting customers.
We’ve included support for both “implicit” SSL (running on port 990), and “explicit” (also referred to as TLS, AUTH TLS or FTPES), running the standard FTP port 21.
How to Upgrade
We’ve added a Knowledge Base article with details on how to enable encrypted FTP in the most common FTP clients, available here:
If you have any questions or need help configuring your FTP client, you can contact us @help@mrhost.ca
Technical Stuff – Implicit vs Explicit vs FTPS vs SFTP
There seems to be a lot of confusion over the different types of secure FTP, as there are several methods of securely transferring files that have been called “Secure FTP” at one point or another:
FTPS
Explicit FTPS is an extension to the FTP standard that allows clients to request that the FTP session be encrypted. This is done by sending the “AUTH TLS” command. The server has the option of allowing or denying connections that do not request TLS. This protocol extension is defined in the proposed standard: RFC 4217.
Implicit FTPS is a deprecated standard for FTP that required the use of a SSL or TLS connection. It was specified to use different ports than plain FTP (usually port 990).
Mr.Host support both of these FTPS methods.
SFTP
Is not actually FTP, but a method for copying files over an SSH connection, using a similar command set.
Mr.Host does not currently support this.
