Server! v4.1.7 released

We have just released version 4.1.7 of our 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.

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. Server! scripting: Session.Terminate and Blacklist

In a previous article we’ve been talking about the new properties and methods introduced by Server! v3 to improve the session object. One of such methods is Session.Terminate that basically instructs the FTP(S) or SFTP server to forcefully terminate the session as soon as the script execution ends.

In such post we have mentioned the addition of another useful function, often used in conjunction with Session.Terminate: the Blacklist function (which name is pretty self-explanatory). In this article we will explain how to use it.

First of all, let’s see the functions definition:

There are 3 parameters:

  1. IPorNetwork: the first parameter clearly should be the specific IP address (e.g.: or the network/subnet (e.g.: that you want to blacklist
  2. AMinutes: this is pretty intuitive too, it is the number of minutes you want the above IP address or network to be blacklisted for (unless you are permanently blacklisting it, see point #3 here below)
  3. AType: this parameter can be either ttTemporary or ttPermanent. If you want to temporarily blacklist the IP/network you will use ttTemporary and the IP/network will stay in the blacklist only for AMinutes minutes. Instead if you use ttPermanent the IP/network will be blacklisted forever (unless manually removed) and the AMinutes parameter will be ignored.

How-to: terminate a client session (or all of them)

As of version 3.0, Server! allows you to forcefully terminate an unwanted client session, or even terminate all active sessions if needed.

You can do so by running the Configuration Manager, switching to the real-time monitor panel, and right-click with your mouse on the session you wish to terminate. A popup menu will appear and let you choose whether you want to end the selected session, or all the currently active sessions.
