ℹ️ Check
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.
✔️ Fix
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.
