Starting from version 3 Norton Commander has client-server capabilities (initially via serial null modem line). It was clear even in times of DOS that OFM actually consists of two parts:
Now those capabilities are reimplemented using more modern technology. Client part can be implemented as a an extension of a browser and there is at least one such an implementation: Firecommander in Google Projects
The second approach for the creating of truly portable OFM is to use Java for both parts. Java can be run inside the browser and that solve the client part of equation. And Java can run on any server and that solve that server part of equation.
In other words the principal idea here is to split OFM into two independent parts communicating using well established and refined HTTP or HTTPS protocol.
This is also provides an interesting capability for X11 based remote solutions such as VNC for administering servers over dial-up lines or other low bandwidth communication lines. Also in this case keyboard emulation can be perfect and does not depend on idiosyncrasies of terminfo database on a particular platform -- the issue that hunts Unix OFMs.
Another reason is the crisis of several implementations, like Midnight Commander, which grow codebase to the extent that it became a complex mess of different libraries that are typical only for Linux. Which created problems with portability and actually discourage usage such OFM as mc as portability outside a couple of platforms (Linux and Solaris) is problematic.
In this case, even usage of traditional implementation of OFM using Java, such as muCommander along with VNC represents much more portable solution as long as JVM is already installed (which is true for all Unix flavors).
The leading Java OFM implementation muCommander is not implemented as client -server. It uses Java just as a portable implementation language. But it can definitely serve as a prototype for a client-server based implementation due to portability of Java.
muCommander the most portable OFM in existence. It is written is Java and currently does not have client-server capabilities. Here is some info from Wikipedia article:
muCommander is a lighweight, cross-platform file manager that will run on any operating system supporting Java. It features a Norton Commander style, dual-pane interface to allow easy manipulation of files with many keyboard shortcuts. Pre-compiled builds are available for Mac OS X, Microsoft Windows, Linux, Solaris, FreeBSD, OpenVMS, and the software can be run from the Internet via Java Web Start.
In 2009, muCommmander was recognized as one of the best file managers on Linux. In 2010, it ranked 76th on the best free software list of PCMag.

[Sept 17, 2003] fmweb - the universal web-based file manager -- not very portable (does not work on Win32).
fmweb is a web-based filemanger written in Java. It can be used to manage the local filesystem or via the TCP/IP network the filesystems of remote machines.
The communication is via HTTP or HTTPS. fmweb has a built-in WWW server.
Although fmweb is a platform-independent java application, it offers many functions that specialized file managers for the operating system provide.
fmweb is a multi-user application, for each user a "document root" can be defined.
fmweb's picture browsing and manipulation functions allow to use it as a web picture album.
fmweb can be used by webspace providers to give the users simple access to their files.
This latest version has been tested on Linux, Windows/NT, Windows 2000 and SUN Solaris. Previous versions also worked on AIX and OS/2 and the new version should work on these platforms too.
freshmeat.net Java File Manager 0.5
About: JFM is an Windows Commander, Krusader, MC, Norton Comander, etc. clone, but written entirely in Java. It has no native parts, and is intended to remain that way. You can use the same file manager in every OS that you run, not having to get used to a new file manager when you boot a new OS.
FileManager servlet is a Java(tm) servlet that implements FileManager. You can use this servlet for example for remote site management: upload/download files, copy/move files, edit files etc. The main advantage is the usage HTTP protocol only for access to your host. So this approach is free from any firewall's restrictions.
How to use it:
a) copy fmanagerPackage.jar into WEB-INF/lib
b) describe FileManager servlet in web.inf file:<servlet> <servlet-name>FileManager</servlet-name> <servlet-class>com.jsos.fmanager.FileManager</servlet-class> <init-param> <param-name>config</param-name> <param-value>path_to_your_configuration_file</param-value> </init-param> </servlet>
c) define a mapping for FileManager servlet in your web.xml file.<servlet-mapping> <servlet-name>FileManager</servlet-name> <url-pattern>/servlet/FileManager</url-pattern> </servlet-mapping>
now you can run this servlet:http://your_host/servlet/FileManager
Parameter config is optional. This parameter lets you define some configuration settings as an initial parameter for your servlet. You must set a path to the configuration file as an initial parameter for FileManager servlet.
Configuration file is a text file, each line describes one parameter in the form of
Empty lines and any line starts with # or // are ignored.
Current version supports the following list of parameters:
# base (initial) directory. By default it will be the root directory of your servletunner.
# title (by default is empty - no title)
# style. Describes a link for your CSS style file. By default is empty. E.g.:
# background color (by default is #3366FF)
# foreground color (by default is #FFFFFF)
# color for visited directories (default is #FFFF00)
#font size (by default is current browser's font)
#font face (by default is current browser's font)
# file extensions for visible files. Here you can set commas separated
# list of extensions. Only such files will be visible. By default
# this parameter is empty (all files are visible)
# file extensions for text editor. Here you can set commas separated list of
# extensions. All such files are editable through this servlet.
# By default it is: txt,htm,shtml,html,java,jsp,cpp,h,jsp,pl,sh,csh,xml,bat,ini
# E.g. :
# head. You can set here some file contains any html-code. This code will be
# outputted at the beginning of the each page. So you can set for example some banners.
# By default this value is empty
# Look and feel mode. By default it is 1 (list of files like Norton Commander for example)
# 2 means Explorer like view
# security mode. Default value is 0 - user may see any available directory
# on your server. If you set it to 1 user may see only initial
# directory and any directory below
# enable/disable functions. Possible values are 1 (enabled) or
# 0 (disabled). By default all actions are enabled.
# enable/disable uploading. Default value is 1
# enable/disable edit. Default value is 1
# enable/disable create directories
# enable/disable copy files
# enable/disable move/rename files
# enable/disable delete files
# how to open files. Default value is 0 - open in place, 1 - open in the
# separate window
# maximal size for uploaded file (in bytes). By default size is unlimited
# authorization flag (See Authorization section below)
# login page
# Date format. By default will use full date.
# You may set here format for date. E.g.:
# localization support. You can set character encoding for input parameters
# here. Default value is ISO-8859-1
You may incorporate this servlet into your portal where your users will be authorized. In order to prevent access to files from not authorized visitors you may use authorized parameter in your config file. Servlet assumes that your authorization procedure will put some object into session (as a flag for authorized users). And name for this object should be described for FileManager as a parameter authorized. Servlet checks session and if there is no such attribute than request will be forwarded or redirected to the page, described as a parameter login.
If login value starts with http than request will be redirected to that site. Otherwise servlet assumes a local resource and forwards request.
1. You can save such configuration file anywhere on your server. Just use the proper path for setting servlet's parameter. Short path (just name of the file) means that your configuration file is saved under the root (docBase) directory of your container.
2. Evaluation version adds an exta © information to the edited file and restricts size for the uploaded files.
For downloading: fmanagerPackage.jar
Sample of config file: fmconf
mcj is a Midnight Commander clone. It links to Ncurses via the Cygnus Native Interface and includes Doxygen documentation.
MCJ is a Midnight Commander clone written in Java as supported by the Gnu Compiler for Java (GCJ). No Java runtime or JDK is required. Mcj links to Ncurses via the Cygnus Native Interface. Doxygen provides nice documentation for reusable projects.
Pure CGI does not provide sufficient flexibility for implementation of OFM. You need Ajax capabilities to have sufficient amount of freedom. Even better is to use CGI as just a layer for communicating commands from client to the server part of OFM.
Drall by Henrik Edlund is Web-based implementation of OFM. Current version is 22.214.171.124. Very interesting idea and one of the two top news for 1999(see also news item about CGI-based implementation). Platforms: Linux and Perl (any system supporting perl)
Drall allows users to access their directories and files remotely without the need of using insecure ftp and telnet. It enables the user to treat the remote file system as if it was on their local hard disk trough a normal web browser. The interface resembles the well known Norton Commander (of DOS fame) and Midnight Commander (of UNIX fame). Drall relies on the server's HTTP authentication and SSL for security. Dual-frame interface makes it easy to overlook file system and the modular design means you only use the features you need. Written in Perl for easy customization and expansion.
SiteMgr - a web site manager. This CGI script will perform most of the file operations required for web site maintenance. You can use it to copy, move, edit, delete and upload files, and to create, move and delete directories. Installation can be done by the user or at the system level.
Easy File Manager allows: the creation of user groups, limiting files size and types on each user account, uploading multiple files from a local computer, URLS, or FTP sites, and management of web protection for certain folder types, among others. Easy File Manager also allows the extraction of archives, editing of existing files, and file archiving, among others.
Platform(s): Perl 5.005 or higher, Unix, CGI access
efileman is a web based file management solution written in perl with the following features: create, copy, move, rename, edit, delete, upload, download, zip, unzip or change permissions of files and directories; multifile operations; multiuser access, password protected with one or more entry points in a directory structure; full skinable, choose a design or create your own; disable or hide functions generally or per user web based user administration; email interface for communication between administrator and user, works with sendmail and the like or SMTP; multilanguage support; works with files inside and outside the html root, in last case the full path will be hidden; extra script part for automatic user account creation.
WebRSH is a CGI program which implements a general purpose web-based computing shell. It provides a command line interface, file manager, text editor, and a few other basic things, while being highly configurable and adaptable to various tasks. It can replace, to some extent, rsh, telnet, and ftp daemons.WebRFM (Web-based Remote File Manager) is a CGI-Perl program aimed at providing a single solution for remote web-based file management. It can replace traditional FTP-based access for that purpose. It is suitable for managing websites, as well as for more general purpose file management tasks.
December 18, 1999 :
December 7, 1999 :
WebRFM 0.3b is now available. The main changes are listed in the changelog.
July 15, 1999 :
Glenn Ellingson is working on a modified version of WebRFM that adds some functionality (locking capability and some other things). His geeWebRFM variant can be found at the geeWebRFM site.

What is it?
WebRFM (Web-based Remote File Manager) is a CGI-Perl program aimed at providing a single solution for remote web-based file management. It can replace traditional FTP-based access for that purpose. It is suitable for managing websites, as well as for more general purpose file management tasks. WebRFM combines a "visible" HTML 3.2 compliant form-based layer (which is in the spirit of the tools currently provided by many large hosting services) along with a "hidden" direct HTTP layer that implements a class 1 WebDAV server. Support for some legacy HTTP methods (which are essentially borrowed from AOLserver and Netscape's Enterprise server) is also provided. While WebRFM can be installed and used by individual users, it is specifically designed to provide a secure system-wide solution that is suitable for usage by ISP's, web-space providers, etc. WebRFM currently runs on UNIX/Linux systems.
WebRFM's "visible" layer provides basic file management capabilities (including form-based file uploading and a built-in text editor) using any HTML 3.2 compliant web browser. The "hidden" layer provides server-side support for many existing clients, ranging from simple PUT-based publishing support for clients such as Amaya , StarOffice , and Netscape's Composer , to full fledged file management capabilities with clients such as AOLpress , Cadaver , DAV Explorer , and the Web Folders feature of Microsoft's Internet Explorer 5. Additional clients that work with WebRFM include SiteCopy , Microsoft's Office 2000 applications (they work with the Web Folders), and Netscape's Communicator Roaming Profiles.
WebRFM implements a virtual-root mechanism, such that each user's access is restricted to his own area (home directory, by default), and it is designed to run in the user's security context (UID/GID) such that OS-based access control and quota limits are also being imposed. A special setuid wrapper to enable this is included. Other wrappers (such as the Apache suEXEC wrapper) can also be used.
WebRFM is free software distributed under the terms of the GNU General Public License.
For more information, you can view the readme file. We also have a very rough static demonstration of WebRFM's primary form-based interface. At the primary site, there is also a Read-Only Live Demonstration.
WebRFM is a relative of WebRSH.
While PHP based OFM are WEB based they are discussed in the previous chapter as PHP is a scripting language, not that different from Perl, Python and Ruby. One example is FSGuide -- a Norton Commander clone used by many hosting firms and individuals for advanced file management through the Web. It features user management (password protection, and access control), advanced file selection dialogs, a multiple file uploader (which can also run any application after uploading), a text viewer, a binary file viewer, a source highlighting viewer, an internal text and binary editor, language support, and much more.
