Internet Daemon

Starting and Stopping inetd

Passwords on JINETD

When you stream the job file JINETD.NET.SYS, it logs on as MANAGER.SYS. As part of the installation of inetd,

you must take care of any password requirements for this job. Two of the ways that you can do this include:

• Add the MANAGER.SYS passwords directly to the job file, then alter the file security afterwards so that only

MANAGER.SYS can read it. For example:

:ALTSEC JINETD.NET.SYS; (R,W:CR;X,L:AC)

• Use the PASSEXEMPT parameter of the JOBSECURITY command (version C.60.00 and later) to control

password exemption.

Starting inetd Interactively

You may also start inetd interactively, though this is not recommended for normal use. To do so, enter the

following command at the CI prompt:

:INETD.NET.SYS

Or, from the POSIX shell enter this command:

$/etc/inetd

When you start inetd interactively, $STDLIST for the Internet daemon is your terminal. This means that all

error and warning messages that normally go to JINETD’s spool file will appear on the screen.

Error and Status Reporting for inetd

While inetd is running, any errors and other status messages that it generates are recorded so that you can

monitor its condition. All errors, regardless of their degree of seriousness, are sent to the $STDLIST device

assigned to inetd. For example, if you streamed JINETD, error messages will appear in the spool file

associated with that job. More critical errors are displayed on the system console in addition to being sent to

$STDLIST. For more information, read “Using inetd Message Logging” later in this chapter.

Stopping inetd

To stop inetd, you abort the JINETD job. Stopping the inetd server (aborting JINETD) will cause subsequent

incoming connection requests to be refused.

1. First find the number assigned to JINETD by entering:

:SHOWJOB JOB=@J

You will see a display of job information similar to the following:

JOBNUM STATE IPRI JIN JLIST INTRODUCED JOB NAME
