Check Text (C-223643r958586_chk)

From the ISPF Command Shell enter: ISHELL Enter /etc/ for a pathname; a CD /etc/ may need to be issued. select FILE NAME inetd.conf If Option -h is included on the otelnetd command, this is a finding.

Fix Text (F-25304r953876_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.
