Fix Recommendation

Configure the startup parameters in the inetd.conf file for otelnetd to exclude option -h.
Note: -h indicates that the logon banner should not be displayed.

Check Contents

From the ISPF Command Shell enter:
ISHELL

Enter /etc/ for a pathname - you may need to issue a CD /etc/
select FILE NAME inetd.conf

If Option -h is included on the otelnetd command, this is a finding.
