4 Configuration
Configuration of the WebNet module is done via the configuration pages accessible from
the WebNet home page described above, under the headline “System Configuration”. The
sections below each describe one such configuration page. To access these pages, a username
and password should be entered. By default, these are “admin” and “admin”, but they
should be changed – see how in section 4.1 below.
4.1 Access Control
Access control can be implemented at a more or less fine-grained level. By default, an
“admin” user exists, with the password “admin”. The “admin” password can be changed
in the access control page. The admin user has access to the web pages in the “setup” section
of the web page area – that is, the web pages we are accessing right now. Also, admin has
full ftp access to the file system, with all privileges (see section 4.1.2 for more information
on FTP). An additional user, “anonymous” also exists, with the password “anonymous”.
This user has read-only ftp access to the web page hierarchy. Other users, perhaps with
limited privileges, can be added by means of the two links on the bottom of the access
control page.
4.1.1 Setup of web users
Web access to certain file trees can be limited to certain hosts and be guarded by user-
name/password protection. For each file tree, the root directory name is entered, and
possibly a host name (‘*’ for any host). A number of users can then be created, with asso-
ciated passwords. One of these username/password pairs has to be entered to access a page
in the given file tree.
4.1.2 FTP to the WebNet
FTP (“File Transfer Protocol”) is used to read and write files from/to the WebNet, for
instance to upload scripts and web pages. You need an FTP client on the PC, and Windows
95/98/NT has a command-line FTP client built in. Alternatively, lots of freeware FTP
clients exist, with more user-friendly file manager-like interfaces.
Most new internet browsers support FTP. The address (URL) is here of the form:
ftp://admin:[email protected].
Netscape is able to upload files using the File menu. Microsoft Internet Explorer 5.0 and
newer allows copy and paste between your local Windows machine and the WebNet.
Connecting to the WebNet can be done by opening a DOS-prompt and issuing the command:
ftp 192.168.4.10
You are then prompted for a username and a password, and you can use “admin”/”admin”
to gain full access.
