Server Type: UNKNOWN_FORMAT
If you see "Server Type: UNKNOWN_FORMAT" in the script log file or wildcards are not working in the RCVFILE command, it typically means that the server is using a directory listing format which Robo-FTP is unable to understand.
The error message in the log may vary depending on the version. In version 3.11 and later, the log file will say, "Directory parsing failed."
If you encounter this issue, please open a ticket with Technical Support and provide information that will enable Serengeti to add support for this new type of directory listing.
If you are using Robo-FTP 3.9.x and previous, add the -d option to the shortcut that launches Robo-FTP to produce a debug file named "dir_debug.txt". This file contains an image of the FTP site directory listing.
If you are using Robo-FTP 3.10.x and later, you do not need to add the -d option. In later versions, Robo-FTP automatically logs directory information to the debug log. Simply export a debug log from the Logging tab of the Configurator.
When running Robo-FTP, use the FTP client applet to log onto the site and attempt to navigate to the intended directory on the server. (It is likely that no files will appear in either of the right two windows of the applet while you are doing this -- so you may have to click the Change button and type in the intended directory, if any.)
When you have done all you can do with the applet, log off, and exit Robo-FTP. Locate the "dir_debug.txt" file (Robo-FTP 3.9.x and earlier) or export a debug file (Robo-FTP 3.10.x and later) and submit that to Technical Support (follow the Technical Support links on Robo-FTP.com).
