Documentation forServ-U MFT & Serv-U FTP Server

The Serv-U server log

The Server Activity > Log pages show logged activity for the server.

The server log shows file server start-up, configuration, and shutdown information. It does not show domain activity information. For activity logs, view the log of the appropriate domain instead. In addition to status information about libraries, licensing, and the current build that is logged when the file server first starts, the server log also contains information about all domain listener status, Universal Plug-and-Play (UPnP) status information, and PASV port range status.

The information contained in the server log is also saved to the Serv-U-StartupLog.txt text file in the Serv-U program data directory. This file is replaced each time the Serv-U File Server is started.

In Linux, the Serv-U program data directory is the same as the Serv-U installation directory. By default, it is /usr/local/Serv-U.

In Windows, the Serv-U program data directory is C:\ProgramData\RhinoSoft\Serv-U. However, in some cases, for backward compatibility purposes, the program data directory may be the same as the Serv-U installation directory. This occurs when the Serv-U.Archive file resides in the installation directory, which by default is C:\Program Files\RhinoSoft\Serv-U.

You can highlight information contained in the log by clicking and dragging the mouse cursor over the appropriate portion of the log. When it is highlighted, you can copy the selected portion to the clipboard.

Freeze Log

Select this option to temporarily pause the refreshing of the log. This is useful on busy systems so you can highlight and copy a particular section of the log before it scrolls out of view. When you have finished, deselect the option to resume the automatic updating of the log.

Clear Log

When the log has become too large for you to view at once, click this button to erase the currently displayed log information. Only log information received after clicking the button is displayed.


To make viewing the different components of the log easier, each different type of logged message is color-coded for quick identification. Clicking this shows the legend in a draggable dialog. Drag the legend dialog to a convenient location so you can use it for reference while you browse the log.

Filter Log

To quickly find and read through specific sections of the log, you can filter it based on a search string. Click this button to bring up the Filter Log window. Provide a search string, and then click Filter to refresh the log to only display log entries containing the search string. To view the entire contents of the log again, open the Filter Log window, and then click Reset.
