To configure Telnet, you will edit two files: the services file, which lists
the individual services that comprise the suite of Internet Services, and the
inetd configuration file, which informs the Internet daemon about
running Telnet on this system.
Editing the Services File
The services file associates official service names and aliases with the port
number and protocol the services use. To enable Telnet, you must edit the
services file. Perform the following:
- Open the services file with an MPE text editor. You may edit the
/etc/services file from the POSIX shell or the
SERVICES.NET.SYS file from MPE/iX, whichever you prefer. Both
file names should point to the same file.
- Verify that the following line exists in the file or add it if it does
not:
telnet 23/tcp
- If the line already exists in the file and it is preceded by a pound
symbol (#), delete the symbol and any spaces before the service
name to enable the service.
- Save the file and exit the editor program.

Chapter 1 "Introduction to Internet Services"
Adding Telnet Service to inetd Configuration
The configuration file for inetd determines which installed Internet
Services are available to users. To add Telnet service to your system, you
need to edit the configuration file for inetd, then have
inetd re-read the configuration. Perform the following:
- Open the configuration file with a text editor. You may edit the
/etc/inetd.conf file from the POSIX shell or the
INETDCNF.NET.SYS file from MPE/iX, whichever you prefer. Both
file names should point to the same file.
- Verify that the following line exists in the file or add it if it does
not:
telnet stream tcp nowait MANAGER.SYS internal
- If the line already exists in the file and it is preceded by a pound
symbol (#), delete the symbol and any spaces before the service
name to enable the service.
- Save the file and exit the editor program.
- Signal inetd to reread the configuration file by entering the
following command at the CI prompt:
:INETD.NET.SYS -c
Or you may enter this command from the POSIX shell:
$/etc/inetd -c
- If you have added the Telnet server to the inetd configuration
file while the Internet daemon is not running, you must start
inetd to start the Telnet server. To do so, stream the job
JINETD.NET.SYS from the CI prompt.
:STREAM JINETD.NET.SYS
