Addtron Technology WebNet manual Configuration

4Configuration

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.

4.1Access 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.

4.1.1Setup 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.

4.1.2FTP 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:admin@192.168.4.10.

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.
