ZServer FTP Channel for use the medusa's ftp server.
FTP Service for Zope.
This server allows FTP connections to Zope. In general FTP is used
to manage content. You can:
Create and delete Folders, Documents, Files, and Images
Edit the contents of Documents, Files, Images
In the future, FTP may be used to edit object properties.
FTP Protocol
The FTP protocol for Zope gives Zope objects a way to make themselves
available to FTP services. See the lib/python/OFS/FTPInterface.py for
more details.
FTP Permissions
FTP access is controlled by one permission: FTP access if bound to a
role, users of that role will be able to list directories, and cd to
them. Creating and deleting and changing objects are all governed by
existing Zope permissions.
Permissions are to a certain extent reflected in the permission bits
listed in FTP file listings.
FTP Authorization
Zope supports both normal and anonymous logins. It can be difficult
to authorize Zope users since they are defined in distributed user
databases. Normally, all logins will be accepted and then the user must
proceed to cd to a directory in which they are authorized. In this
case for the purpose of FTP limits, the user is considered anonymous
until they cd to an authorized directory.
Optionally, users can login with a special username which indicates
where they are defined. Their login will then be authenticated in
the indicated directory, and they will not be considered anonymous.
The form of the name is @ where path takes the form
[/...] For example: amos@Foo/Bar This will
authenticate the user amos in the directory /Foo/Bar . In addition
the user's FTP session will be rooted in the authenticated directory,
i.e. they will not be able to cd out of the directory.
The main reason to use the rooted FTP login, is to allow non-anonymous
logins. This may be handy, if for example, you disallow anonymous logins,
or if you set the limit for simultaneous anonymous logins very low.
