The following UNIX predefined or generic group names:
wheel
Many of these user and group names can provide mechanisms that intruders can use
to compromise UNIX system security or integrity.
The OSS environment does not provide common UNIX default user names and user
IDs unless they are explicitly created by a site administrator. However, equivalent OSS
user names and user IDs do exist. For example, the privileges normally associated
with the UNIX user name root and the user ID of 0 exist for the OSS user ID (UID) of
65535 (the super ID), which is usually the user SUPER.SUPER.
The OSS environment is incompatible with the following UNIX user and group
conventions:
•
The UNIX super ID has a UNIX UID of 0. The OSS user with an OSS user ID
(scalar view of the NonStop operating system user ID) of 0 is NULL.NULL by
default.
•
The UNIX super group has a UNIX GID of 0. The OSS group with an OSS
group ID (group number from the structured view of the NonStop operating system
user ID) of 0 is NULL by default.
•
Single UNIX user names such as root are always login names. The OSS user
name is the complete NonStop operating system user name and group name pair
(for example, USER.FREDA) unless an alias has been created for the underlying
user ID (for example, when freda is an alias of the user ID for USER.FREDA).
