WU-FTPD 2.6.1 release notes (5900-1547, January 2011)

• Treatment of UIDs and GIDs as Guests
This feature allows you to force the user IDs (UIDs) and group IDs (GIDs) in a range
to be treated as guests.
The syntax for treating UIDs and GIDs as guests is as follows:

realgroup <groupname> [ groupname ... ]
realuser <username> [ username ... ]
• Upload and Download Ratios
You can set the upload and download ratio to limit the user’s ability to upload and
