HTTP (Help)
HTTP is the protocol used by the World Wide Web. The server-based user help for the terminal is distributed as a tree of HTTP links and is on the installation CD. Terminal help can be installed on a WWW server, but because of network traffic or your configuration, it may be more desirable to configure a local HTTP server and install the help tree there. HTTP configuration is based upon the HTTP server software used, so refer to the installation documents that come with the HTTP software you are installing. There are no special requirements for using the help subsystem.
Serial Internet Connections
DNS routing has to be through either the terminal’s serial port (Select System Setup Connectivity Serial Internet) or the Ethernet 10/100 Base-T connection (Select System Setup Connectivity Internet), not both. The resolver does not look up more than one domain. Linux requires that DNS be set up before working with SLIP/CSLIP or PPP. It will not accept the DNS information from the DNS server, so you must manually enter this in the DNS dialog section of the Serial Internet dialog box or Internet dialog box if you intend to use the PPP server’s DNS.
PPP
PPPstands for Point-to-Point Protocol and is a standard serial line Internet protocol. Instructions for configuring the PPP server is best left to the documentation associated with the server, but the following restrictions apply to the client-side implementation for the terminal: Microsoft Windows NT RAS can be set up to use a variant of CHAP (Challenge/Handshake Authentication Protocol); the PPP connection will not work with this.
SLIP
SLIP stands for Serial Line Internet Protocol and is another standard serial line Internet protocol. It is does not provide error detection or retransmission services and does not compress data. Refer to the server documentation for configuration of the SLIP server. On the terminal, the host name and server name must correspond to entries in the host table.
