Check Text ( C-16457r294228_chk )
Determine if the "ftp" daemon is running by running the following command:
# grep "^ftp[[:blank:]]" /etc/inetd.conf

If an entry is returned like the following line, the "ftp" daemon is running:
ftp stream tcp6 nowait root /usr/sbin/ftpd ftpd

If the above grep command returned a line that contains "ftpd", this is a finding.
Fix Text (F-16455r294229_fix)
Disable "ftp" daemon entry in "/etc/inetd.conf" using command:
# chsubserver -r inetd -C /etc/inetd.conf -d -v 'ftp' -p 'tcp6'

Reload the inetd process:
# refresh -s inetd
