Introduction to Internet Services
Overview of Internet Services
Overview of Internet Services
Internet Services on the HP 3000 consist of eight individual services
that enable the HP 3000 to communicate with other nodes on an
internetwork. The program and configuration files needed to run
Internet Services is part of the MPE/iX Fundamental Operating
Software. No separate software product is necessary to use Internet
Services.
The services are briefly described in Table 1-1
Summary of HP 3000 Internet Services
NOTE Throughout this manual, the term daemon, which is familiar to UNIX
users, and the term server are used interchangeably.

Service Description
inetd The Internet daemon inetd is the master serverfor the groupof Internet Servicesrather than
an individual network service. You must install and configure inetd on your system to use the
other services as listed below.
telnet The telnet server uses the standard virtual terminal protocol to allow users on a remote node
that supports Internet Services to log on and run most applications on the host HP 3000.
bootpd The Bootstrap Protocol daemon, or bootpd, is used to boot, or start, devices such as routers,
printers, X-terminals and diskless workstations. Client systems use bootpd to find their own
IP address and the name of the boot file to load into memory and execute.
tftpd The Trivial File Transfer Protocol daemon tftpd is used to transfer the boot files needed to
start network devices. In this implementation of Internet Services, tftpd enables an HP 3000
to boot network printers.
remsh The remote shell client allows a user on an HP 3000 to access a remote UNIX host and execute
a UNIX command or script without logging on.
ftp The File Transfer Protocol (FTP) is an ARPA service that allows users to transfer files among
other networked systems. FTP is the file transfer program that uses the ARPA standard File
Transfer Protocol. FTP can be used with systems supporting the ARPA FTP service such as
other HP systems, UNIX systems, and non-UNIX systems.
Samba Samba/iX is a suite of programs which allow clients to access a server’s file space and printers
via the Server Message Block (SMB) protocol. It allows the MPE/iX shell operating system to
act as a file and printer server for SMB clients, which are primarily, Windows NT, Windows 95
and Windows for Workgroups
DNS BIND (Berkeley Internet Name Domain) is an implementation of the Domain Name System
(DNS). A complete implementation of DNS BIND/iX is available on MPE/iX. DNS BIND/iX will
enable MPE/iX host to act as a DNS server, both responding to queries as well as
communicating with other DNS servers on the local network and the Internet.
