Summary of HP e3000 Internet Services
NOTE Throughout this manual, the term daemon, which is familiar to UNIX users, and the term
server are used interchangeably.
System Requirements
The Internet Services program and configuration files come with version C.55.00 or greater, of the MPE/iX
Fundamental Operating Software (FOS). (The exception to this is the Telnet Client, which was made
available to customers on the earlier version of MPE/iX, C.50.00.) As part of MPE/iX FOS, Internet Services
can run on any Precision Architecture-RISC model of the HP e3000. They are not available on earlier “classic”
HP e3000 computers running MPE V.
To run Internet Services, you must:

Service Description
inetd The Internet daemon inetd is the master server for the group of Internet Services
rather 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 e3000.
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 e3000 to boot network printers.
remsh The remote shell client allows a user on an HP e3000 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 for MPE/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.
