Why did my license revert back to FREE?

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

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

Syncplify.me Server! v4.2.0 released

We have just released version 4.1.9 of our Syncplify.me Server! software. This version features the following improvements:

  • Added: support for AWS Load Balancer’s “proxy protocol” (HAProxy protocol v1) to correctly identify the remote client IP address from multi-node load-balanced EC2 instances inside the AWS cloud
  • Added: AutoOptimizeSocket registry setting to automatically optimize the socket’s inbound/outbound buffer sizes and ultimately improve upload/download speed
  • Improved: performance and reliability of the [%USER_HOME%] finder function inside the VFS subsystem
  • Fixed: directory list timer and counter in the FTP protocol handler
  • Fixed: few other minor and rarely occurring issues

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.

Syncplify may drop 32-bit/legacy support in future versions

Almost 7 years ago, Microsoft has dropped support for 32 bit versions of their server operating system; in fact, as of Windows Server 2008 R2 only 64-bit server OSs have been released by Microsoft. Later, support for 32-bit versions of server OSs has been dropped, so we can safely say that – today – only 64-bit versions of Windows Server are available and supported.

MongoDB (the database we use as a back-end to Syncplify.me Server!) is considering a similar choice. And even though they still support 32 at the time this article is being written, their 32 bit version comes with limitations that make it unsuitable for large-scale deployments.

Furthermore, according to our license database, only about 1% of our customers are still using 32-bit versions of our software, and less than 0.2% of them have active support and maintenance subscriptions. Simply put, almost nobody is using 32-bit versions of our software anymore.

For all of the above reasons, Syncplify’s management is currently considering the possibility to drop 32-bit support in future versions of our flagship software (Syncplify.me Server!) and possibly all other software titles we design and develop.

Syncplify.me Server! v4.1.9 released

We have just released version 4.1.9 of our Syncplify.me Server! software. This version features the following improvements:

  • Added: support for the XCUP, XMKD, XCWD, XRMD commands in the FTP(E/S) protocol handlers; even though such commands are deprecated by the IETF protocol standard, some FTP clients still use them, so we now support them even though we don’t advertise them in the FEAT response

Syncplify.me Server! v4.1.8 released

We have just released version 4.1.8 of our Syncplify.me Server! software. This version features the following improvements:

  • Added: support for the XPWD command in the FTP(E/S) protocol handlers, previously only PWD was supported

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.

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

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

Syncplify.me Server! v4.1.7 released

We have just released version 4.1.7 of our Syncplify.me Server! software. This version features the following improvements:

  • Fixed: bug in the SSH “Shell” subsystem that prevented the user to be placed in the correct home directory upon opening a shell
  • Fixed: bug that prevented the TLS socket closure notification packet from being sent (only on Active FTPS data connections, no other protocol was affected)

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.

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

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

How to use VFS.ImportFile and VFS.ExportFile

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
