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:

  1. 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.

  2. Verify that the following line exists in the file or add it if it does not:

    telnet 23/tcp

  3. 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.

  4. Save the file and exit the editor program.

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:

  1. 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.

  2. Verify that the following line exists in the file or add it if it does not:

    telnet stream tcp nowait MANAGER.SYS internal

  3. 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.

  4. Save the file and exit the editor program.

  5. 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

  6. 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
