Going back to the question about limiting FTP users, I regret that I don't have a SCO server available to test, however many unix OS variation have a file /etc/ftpusers which work in the reverse to what you might expect. It is a list of accounts that are not allowed to FTP into this server. It is slightly counter intuitive (to me at least ) but I wrote a simple script that I run daily to read /etc/ftpusers.allowed and re-write /etc/ftpusers. It was something like this:-
Would that help? You need to be careful that the input file doesn't have blank lines (which will match every record) or short user ids that are contained within longer ones. Perhaps you should make this a two step process:-

DESCRIPTION
HP-UX supports MCA Error Recovery to ensure that certain Machine Check Aborts (MCA) caused by transient errors do not crash the operating
system.
The dynamic tunable is used to enable or disable the MCA Error Recovery functionality. If disabled, an MCA will cause the system to initi-
ate a crash dump and then a system reset (normal legacy behavior). If enabled, certain MCAs caused by transient events will be recovered
and system execution resumed. The recovery action depends on the type of MCA and can include termination of a user process.
Who Is Expected to Change This Tunable?
System administrators can change the value of depending on the usage of the system.
Restrictions on Changing
MCA Error Recovery is only supported on Dual-Core Processors 9100 Series and later. On unsupported systems, MCA Error Recovery will be
disabled by default and changing the tunable will not be allowed.
WARNINGS
All HP-UX kernel tunable parameters are release specific. This parameter may be removed or have its meaning changed in future releases of
HP-UX.
Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation,
some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun-
able values, consult the documentation for the kernel software being installed. For information about optional kernel software that was
factory installed on your system, see at
