Tested Web Browser
The ChemWeb Server was tested successfully with the following Web browsers:
- Microsoft Internet Explorer 6.0 SP1 with Sun Java 1.4.1
- Netscape 7.01 with Sun Java 1.4.1
- Mozilla 1.3 with Sun Java 1.4.1
- K-Meleon Version 0.7.1 with Sun Java 1.4.1
The listed Web browsers display all screens of the ChemWeb Server correctly and allow all required
operations. Other Java-capable Web Browsers may cause faulty displays or operation of the ChemWeb
Server.
Explanation of terms
Client – Server architecture
System of “distributed intelligence”, the client establishing the connection to the server to call on the
services offered by the server. Some server applications are able to serve several clients
simultaneously.
10BaseT – 10Mbit/s BASEband Twisted Pair
Cabling is star-shaped, starting from a hub as the central active component. An at least two-pair cable
of category 3 with 100 ohms impedance is used which transmits the data separately for the
transmitting and the receiving direction. As plug connectors, 8-contact RJ45 types are used. The max
length of a segment (= connection from hub to terminal equipment) is limited to 100m.
BootP – Boot Protocol
This older protocol for booting PCs without hard disk via the network is the predecessor of DHCP.
Even the latest DHCP servers still support BootP inquiries.
Currently BootP is mainly used to assign an IP address to embedded systems. For this purpose, a
reserved entry must be filed on the DHCP server, in which a fixed IP address is assigned to the MAC
address of the embedded system.
Browser
Browser is the client program with graphical user interface, which allows the user to display web
pages and to use other Internet services.
CGI
CGI is the access to a password-protected HTML page of the ChemWeb Server. A log-on with CGI
login and password is always required.
Client
Clients are computers or applications, which use services from so-called servers. An example of such
services is the provision of HTTP and FTP.
DHCP – Dynamic Host Configuration Protocol
Dynamic allocation of IP addresses from an address pool. DHCP is used to assign IP addresses
automatically to network users in a TCP/IP network.
Ethernet
Ethernet is the technology currently most often applied for local networks. There are three different
Ethernet topologies – 10Base2, 10Base5 and 10BaseT –; the transmission rate is 10 Mbits/s.
