SCO UNIX 3.2v2 Maintenance Supplement and
UNX340
SCO have produced a major supplement to their existing 3.2v2.0 release
of the UNIX operating system. Whilst 3.2v4.0 will ship within the next 3 months, this
supplement updates existing systems at no charge with a number of changes. Installation of
this supplement on any new 3.2v2 installations will take care of all existing fixes which
Apricot routinely advises to be installed.
To summarise, the Maintenance Supplement includes or supersedes:-
- UNX257 Security Enhancement
- UNX251 Kernel Locking/Inode supplement for ISA bus machines
- UNX279 Kernel Supplement for ISA machines
- UNX304 X/Open Portability Guide release 3 compatibility
- EFS102 Scoterm Supplement for SCO XSight
- Double Panic fix also known as the console driver fix or SCOL010
The supplement must only be installed on 3.2v2.0 systems. A system which
runs 3.2.0 revision of UNIX must not have this supplement installed until a full 3.2v2
operating system has replaced the 3.2.0.
The following items have been extracted as features of this supplement:-
- Enhanced security handling and recovery including removal and unretiring
of users
- Introduction of "hushlogin" to prevent copyright and other
messages during login. Works with TCP/IP.
- Allows minimum password length to be more easily controlled.
- Heavy serial line input no longer hangs the machine.
- Console keyboard handling anomalies corrected.
- NFS performance optimisation.
- Double Panic fix as notified above.
- Allows su to work to other than root logins.
Unfortunately a minor error exists with the Maintenance Supplement
involving /bin/login. To remedy this issue UNX340 should be custom installed before taking
the system multi-user but after rebooting on the new 3.2v2.1 kernel built from the
Maintenance Supplement installation.
The Maintenance Supplement consists of three HD 3.5" diskettes and
UNX340 uses one DD 3.5" diskette.
