SMB2WWW Gateway software
SMB2WWW is a gateway between WWW and the MS Windows (WfW,95,NT), OS/2
and Lan Manager networks, using the session message blocks (SMB) protocol.
This means that you can browse these networks and download files using a
single executable in the "cgi-bin" directory of a WWW server.
How it works
When you issue a request to the WWW server like "/cgi-bin/smb2/lanserver/",
the gateway program "smb2" is executed with "lanserver/" as it's parameter.
The first thing that has to be determined is the IP address of "lanserver".
This is done by sending a broadcast (the address of this broadcast is
currently hardcoded) to all computers on the local net. The server with the
name "lanserver" should respond and the IP address is determined.
Once the IP address is known, a connection using the SMB protocol is made
to this server and three lists are requested. The first one is a list of
all the shares (drives) on this server. The second one is a browse list of
all the server within the same workgroup as "lanserver". Thirdly a
workgroup list is returned; this is a list of all known workgroups and
their master server/ browser.
Each server, either in the browse list or a master browser can be contacted
in exactly the same way. A master browser can have other servers in it's
workgroup not known to "lanserver".
By selecting a share of a server, a directory of list is obtained. This
directory list contains references to files and other directories. Each of
these files can be downloaded; for all known extensions a correct mime
type is supplied, so the appropriate application may be launched.
To download a whole directory and all of it's subdirectories, just click on
the attribute of this directory or on "TAR current directory" on top of
the directory list. Save this file with "tar" as extension and use tar or
for instance WinZip to extract this archive.
One of the most common error is Error connecting to host. This
means that there isn't any computer responding to the name supplied in
the request. Most likely this computer is just turned off, while the
master browser hasn't noticed this (yet).
Furthermore the gateway can only browse shares that are not protected by
passwords. When you access a share which requires a password, you get the
following message: Error connecting to share.
Finally, you may get the following message: Access denied. This is
a message of the gateway self. The administrator of the server can
restrict access to this gateway to local users (based on their IP address).
Since every time a request is made to the gateway a process is started, the
load of this gateway on the server can become quite high.
This gateway software was not constructed from scratch. It is in fact an
adaptation of the smbclient implementation as supplied in the
SAMBA package. This SAMBA package is the unix implementation
of client and server software of the SMB network environment. This package
is free software under the terms of the GNU General Public License (GPL) and is
copyrighted by Andrew Tridgell. This means that the SMB2WWW gateway should
also be free software under the terms of (GPL).
It is currently under development; there needs to be some (a lot) of code
cleaning be done. Maybe this software will be included in the SAMBA
package some day. But until that day has come, please don't bother Andrew
Tridgell with any problems about this gateway.
For 'configuration' (hack it yourself) see also these notes.
Where to get it
The latest version can downloaded here. It is in
fact an adaptated version of the SAMBA package (I said there needed
to be some code cleaning). To compile it, untar it and do a "make smb2".
Copy smb2 to you "cgi-bin" directory of your http server and y're up and
The author of this gateway software can not be held responsible for any
copyright infringes when using this gateway. The files accessed by this
gateway were already accessable over the internet, but this gateway just
makes it a bit easier.
