GCM ciphers added to TLS

We’ve just released CompleteFTP 12.1.2, and it includes GCM (Galois Counter Mode) ciphers for TLS. GCM ciphers are beginning to be widely adopted because they are more efficient and more secure than the CBC equivalents. It is available for download now.

Configuring active directory groups

We were recently asked by a user if CompleteFTP could treat active directory groups like users, so that each group has its own home directory and associated settings.

Yes, this can be done by adding new authenticators – configurable plugins.  Currently, Windows users when they login without being explicitly set up in CompleteFTP are subject […]

CompleteFTP clustering basics

Clustering is when a group of several servers work together to accomplish a task or function, appearing as a single unit to clients.  The primary purpose is to provide resilience – a server in the cluster may fail but clients should ideally not even be aware of it.

The CompleteFTP User Guide has a useful section […]

Modifying folder paths in CompleteFTP

A CompleteFTP user recently asked us about an easy way to change lots of folder paths. They are moving all their folders in CompleteFTP to a different location. They have far too many folders to update the paths one by one in the manager application.

Fortunately, there is an easier way.

All of CompleteFTP’s configuration data […]

How to enable long filenames in CompleteFTP

Windows has restricted the length of filenames to 26o characters for many years. For most CompleteFTP users, this isn’t an issue, but occasionally other applications generate ridiculously long filenames that they then need to send to CompleteFTP.

With Windows 10 and Windows Server 2016, this restriction finally has a workaround (although it is not the […]

How secure is SFTP?

SFTP and SSH
SFTP is a network protocol for transferring files securely over a computer network. Its full name is the SSH File Transfer Protocol, and as it implies, SFTP is a set of commands that runs over another protocol known as SSH, or Secure Shell.

SSH is what provides SFTP with its security, and so […]

Distributing private keys for SFTP servers

A common method of authenticating users in SFTP servers such as CompleteFTP is public key authentication.

In public key authentication,  what is called a key pair is used, consisting of two related cryptographic keys: the public key and the private key. The special property of any key pair is that data encrypted with one can only […]
