About accounts
often asks the user to distinguish between three types of users:
Anonymous 	 For use by anyone who can connect to the server, these users log in as ftp or anonymous and submit their email address as the password.
Guest 	 Users with accounts in /etc/ftpusers but not full accounts on the system.
Real 	 Users with accounts on the system.

Menu Commands

The File menu
File Load /etc/ftpaccess 	Open /etc/ftpaccess, the standard wu-ftpd configuration file, for editing.

User Classes
The User Classes Panel
The User Classes Panel
The User Classes Panel
This panel allows you to create user classes for certain IP addresses or blocks of addresses and to control the privileges of those classes. For example, this enables you to allow anonymous or guest users greater than normal permissions when they log in from certain machines.
To create a new class, hit the Add Class button and, in the resulting dialog box, enter the name of the new class, the privilege levels that can belong to the class (more on this below) and the IP address for that class. A * character can be used to define a block of addresses. (For example, 127.0.0.*includes all local users.) When done, hit OK.
Back in the User Classes panel, you can select a class and modify its description and behavior. The IP address can be modified. The class can be defined to include anonymous, guest and/or real users from that address. Checking the Autogroup to box causes logins in the class to be assigned to the selected group and given its privileges.
The right side of the panel allows classes to be assigned limits on the number of simultaneous logins during specified times. You can also specify the message to be shown when the user limit is exceeded.
In the screenshot, real users logging in from 127.0.0.* are autogrouped to jsinger and only one user in that class is allowed at any time.

Directories
The Directories Panel
The Directories Panel
The Directories Panel
This panel allows you to specify the root directory for anonymous and guest users. (Real users see the real filesystem.) It also allows you to specify the password and shadow password files to be used. If no file is specified, the system file will be used by default.
In the screenshot, anonymous users see a filesystem rooted at /home/ftp/pub, while guest users have default access. Special password files are used in place of the system files.

Security
The Security Panel
The Security Panel
The Security Panel
This panel allows you to specify various security options. The Noretrieves window allows certain files or directories to be blocked from downloading. Hit the Add button and select the file to be blocked. Select an entry and hit Remove to take the file off the list.
Number of allowed failed logins causes connections to be closed after the specified number of login failures.
Checking Permit SITE GROUP allows users to change the group they belong to with the SITE GROUP command.
Permission to use the chmod, delete, overwrite, rename and umask commands can be extended or denied to anonymous, guest and/or real users.
Anonymous users are expected to supply their email address as a password. The degree of enforcement can be controlled.
No 	There is no checking of the given password.
trivial 	The password must contain an @ character.
RFC822 	The password must be in the form of a valid address.
If the Enforce box is checked, logins failing the test will be denied; otherwise a warning will be issued.
In the screenshot, the /bin and /sbin directories and the /etc/passwd file are blocked from downloads. Connections are dropped after 5 failures, SITE GROUP is forbidden, commands are forbidden to anonymous users and allowed for guest and real accounts. Anonymous users submitting non-RFC-compliant email addresses are warned.

Messages
The Messages Panel
The Messages Panel
The Messages Panel
This panel allows you to specify messages to be shown to the logged-in user.
Select a file for the banner to be displayed on connection (before login). Some extremely old clients may be confused by a banner.
The hostname can be specified. This will be reported to the user upon login, and can also be inserted in other messages (as %L). If no hostname is given, the real hostname will be used.
Similarly, an administrator email address can be defined for insertion in messages (as %E).
Check the boxes to cause messages and READMEs to be shown to the user every time the triggering event (explained below) occurs; otherwise they will only be shown the first time.
Hit the Add Message button to indicate text to be displayed to the user. You will be prompted for the location of the text file, whether it will be displayed on login or on change to a specified directory and whether it will be displayed for all user classes or particular ones.
Similarly, the user can be notified of README files upon login or change to a directory.
In the screenshot, the text in /home/ftp/welcome.txt will be displayed on connection. The hostname camelot and the admin address jsinger@leeta.net will be inserted in messages but no messages or READMEs have been defined yet.

Logging
The Logging Panel
The Logging Panel
The Logging Panel
This panel allows you to to control what activities will be logged (to /var/log/xferlog). Anonymous, guest and real users can have different events logged, including issued commands, uploads, downloads and security violations (like login failures).
Checking Redirect log to syslog sends the log entries to the system log instead of the log.
Mail can be sent to the administrator when files are uploaded. The From: address of the mails, the mail server and the administrator's email address can be specified.
In the screenshot, all commands and transfers are logged, as are security violations by real users. Uploads are signalled by a message to admin from Upload Notice sent through the default mail server.

Ratios
The Ratios Panel
The Ratios Panel
The Ratios Panel
This panel allows you to restrict the usage of anonymous and guest users. Each of these restrictions can be applied to anonymous or guest users.
Upload/download ratio 	For example, setting this to 1:5 requires users to upload 1 megabyte of data for each 5 megabytes downloaded. Setting this to an optimum value is key to your success as an aspiring w4r3z kiddi3.
Time limit 	Allow users to connect for this amount of time.
Upload limit 	Set the maximimum number of bytes that can be uploaded per session.
Download limit 	Set the maximimum number of bytes that can be downloaded per session.
Files and directories can be exempted from upload and download limits.
In the screenshot, ratios are off, anonymous users are allowed 15 minutes and 10 megabytes of downloads per connection.

Uploads
The Uploads Panel
The Uploads Panel
The Uploads Panel
This panel allows you to control where and how users are allowed to upload files. Hit Add to a new rule set, Edit to modify the selected set and Delete to remove the selected set.
Each set applies to users with a specified root directory and effects a specified upload directory. The upload directory may be globbed (for example, /home/ftp/upload/* includes all contents of /home/ftp/upload).
Uploads can be permitted or denied, and the permissions of the created files and their owner and group can be set. The ability to create new directories within the existing directory can be granted or denied.

Virtual Hosts
The Virtual Hosts Panel
The Virtual Hosts Panel
The Virtual Hosts Panel
The following items can be specified for each address:
Root directory 	What the logged-in user sees as the filesystem root (/).
Banner 	A file whose contents will be displayed to the user upon connection. The file location is relative to the root set above.
Logfile 	Transfers will be logged to this file.
Passwd file 	An alternate password file can be specified. Otherwise the system password file will be used.
Shadow file 	An alternate shadow password file can be specified. Otherwise the system shadow password file will be used.
Hostname 	The hostname displayed upon login and inserted as %L in message files.
Administrative email 	The email address to be inserted as %E in message files.
Anonymous logins can be allowed or denied.
Real users can be allowed or denied access to the virtual server. Specific user can also be allowed or denied access.
In the screeenshot, the virtual host 211.22.55.114 has a filsystem rooted at /home/ftp/virtual on the real system. It uses separate password and shadow password files in /home/ftp, displays the hostname ganesh and the admin address root and allows anonymous logins and logins from all real users.
