Introduction to 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.

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 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 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.
