What’s new in Syncplify.me Server! v5

  By ,
Syncplify.me Server! version: 5.0.0+

While the step from v3 to v4 was somewhat “epic” (as 80%+ of the code was rewritten from scratch) the upcoming Syncplify.me Server! v5 will, instead, build upon the rock-solid foundation of v4 and expand and improve its features significantly. Version 5 will also be our most cloud-enabled version to date.

Here’s a list of some of the most important upcoming new features our users will find in Syncplify.me Server! v5: Continue reading

No, we’re not vulnerable to the libssh attack CVE-2018-10933

  By

Many of our customers these days have sent us emails asking our team if Syncplify software products are affected by the libssh vulnerability documented in CVE-2018-10933.

Good news: none of our software products is vulnerable.

As mentioned in previous articles in this knowledge base, our products are not based on 3rd party open source libraries and solutions (like OpenSSL, OpenSSH, libssh, …) therefore our software does not inherit their bugs.

Syncplify.me Server! v4.2.2 released

  By

We have just released version 4.2.2 of our Syncplify.me Server! software. This version features the following improvements:

  • Fixed: bug that prevented correct import of virtual folder permissions when converting from an old version 3.x
  • Fixed: incorrect log line human-readable comment upon file rename

Warning: upgrading to this version from any version prior to 4.0.34 will invalidate your license, so please if you are a customer – before you upgrade – contact us to request a license reset.

Note: if after the update you notice any unexpected behavior in the web interface, just hit Ctrl-F5 in your browser; that will force the browser to reload the page as well as all back-end scripts and update the ones that may have been cached from previous versions of the software.

As usual you can download this new release from our website.

Why did my license revert back to FREE?

  By , ,
Occasionally we receive emails from customers whose paid license has reverted back to “free” or “freeware” mode, and they ask us why that happened.

To reduce the phenomenon of software piracy, Syncplify.me Server! binds its licenses to a so-called System-ID upon their activation. This means that, once a license has been activated, it is bound to that System-ID forever, unless we reset it (thus allowing activation on a new machine or VM).

You can find your System-ID in the License page of the SuperAdmin web interface:

Automatic upload/download speed optimization

  By ,
Introduced in v4.2, there’s a registry setting that allows Syncplify.me Server! to automatically choose the socket’s inbound and outbound buffer sizes in an attempt to optimize upload and download speeds.

This setting cannot be configured in the web interface, the only way to set it is at Windows registry level. Restarting the Syncplify.me Server! system services is not necessary, as this setting is pulled from the registry every time a new incoming connection is served. Continue reading

How to: SFTP authentication via one-time passwords (OTP)

  By , , ,
Syncplify.me Server! version: 5.0.0+

Occasionally our customers ask if it’s possible to implement some form of one-time password (OTP) authentication for their SFTP users. Considering the complexity of the SSH authentication scheme, such task is definitely not trivial. To ease the process, Syncplify.me Server! V5 adds two new event-handlers and several functions to the scripting framework. This article explains how to use them to accomplish OTP authentication over SFTP. Continue reading

How to: fix a white-list or safe-list suddenly empty

  By , ,
Syncplify.me Server! version: 4.0.0-4.1.4

Occasionally users report that their white-list or safe-list in the web management interface suddenly shows up as “empty” and they cannot add any more IP addresses or networks to it. That bug was already previously documented in our knowledge base, and has been resolved/fixed as of version 4.1.5.

The misbehavior is caused by the fact that an Admin has added the same IP or network twice to the list(s).
Upgrading to the latest version will prevent Admins from adding any more duplicates… but it does not sanitize the existing lists, so you will still have to “clean” your lists manually before you can see them again. Continue reading

  By , , ,
Syncplify.me Server! version: 4.1.6+

As of version 4.1.6, Syncplify.me Server! added 2 new functions to the VFS object for you to use inside your event-handling scripts (requires the Ultimate edition of the software).

Say, for example, that you have an encrypted VFS, like a VFS of type DiskAES256 as shown in the picture here below: Continue reading
