Telnet Service

Overview of Telnet Service

Telnet service consists of a Telnet client and a Telnet server.

The Telnet server uses the standard virtual terminal protocol,

originally developed by the Advanced Research Projects Agency (ARPA)

to allow users on a remote node that supports the Telnet and TCP/IP

protocols to log on and run applications on the host HP 3000. When you

conﬁgure and enable Telnet on your system, inetd, the master server

for the Internet Services, will listen for connection requests from Telnet

clients. If the request comes from an authorized client node (for

example, one that is allowed Telnet access to the host via the allow

entry in the inetd security ﬁle), inetd will accept the request and start

a Telnet session for the requesting client.

The Telnet client allows users on your system to log onto and run

applications on a remote host system that supports Telnet access. On

MPE/iX, the Telnet client is the program ﬁle TELNET.ARPA.SYS.

Read “Implementation Differences” for a discussion of the differences

between the implementation of the Telnet server on the HP 3000 and

the Telnet server as it is implemented on HP-UX systems.
