The "IP Address Alias Manager" administers network addresses for configured IP interfaces - enabling the virtual domains services in both FTP server and mail delivery.
Currently UnixWare 7 does not have a manager to do this and the administrator has to set up the aliases by hand.
Included in the image is a set of HTML pages that are added to SCOhelp at install time. The doc is under Networking -> Administering TCP/IP and Internet services -> Configuring IP Address Aliases.
The package is fully removable and can be installed with the command:
# pkgadd -d <mount-point> ipalias
Lsof lists information about files opened by processes. An open file may be a regular file, a directory, a block special file, a character special file, an executing text reference, a library, a stream or a network file (Internet socket, NFS file or UNIX domain socket.) A specific file or all the files in a file system may be selected by path.
In addition to producing a single output list, lsof will run in repeat mode. In repeat mode it will produce output, delay, then repeat the output operation until stopped with an interrupt or quit signal.

proc is a tool for displaying information from a running process or core image. It accepts either the name of a core file, a process id or a pathname in the /proc directory. By default, it produces a summary listing of process level information, similar to that provided by the ps command. You can ask for a fuller listing and for detailed reports about each LWP in the process, including the contents of the registers. You can also get a memory map of the process. For full details see the manual page, proc.1.
The current source will build under UnixWare 2.1.x or UnixWare 7. The distribution was built using UnixWare 7, bl15.2v1e. To build, simply invoke: make -f proc.mk
proc is a dynamically-linked ELF binary that will run on UnixWare 2.1.x or UnixWare 7 (gemini). It may be installed anywhere that is visible from your PATH.
proc does not run under OpenServer, since it requires the facilities provided by the /proc filesystem.
msize is a simple shell script that uses proc -m to print out the memory size of a running process. usage is: msize process_id.
proc was written by Joel Silverstein, jds@sco.com. The source is owned by SCO and will probably be part of a future SCO product. msize was written by David Prosser, dfp@sco.com.
SCOadmin for Intranets provides you with tools to perform server administration functions from any JAVA capable web browser. Tasks which have traditionally been performed by the system administrator are now presented in an easy to use, platform-independent fashion by coupling SCO Visual Tcl technology, Java, and the SCOadmin Framework. By offering these limited function, applications directly to the end-user, the system administrator can reduce the amount of time that they are called out to perform routine tasks such as adding users, or stopping print queues for paper jams.
This release of SCOadmin for Intranets is intended for use on the SCO Forum release of SCO UnixWare 7 (codename "Gemini"). Support for other SCO operating system platforms is forthcoming.
For details on the contents, installation, licensing and support for this release of SCOadmin for Intranets, see the file http://www.sco.com/skunkware/uw7/admin/scofi099b.README.
sudo allows a permitted user to execute a command as the superuser (real and effective uid and gid are set to 0 and root's group as set in the passwd file respectively).
sudo determines who is an authorized user by consulting the file /etc/sudoers. By giving sudo the -v flag a user can update the time stamp without running a command. The password prompt itself will also time out if the password is not entered with N minutes (again, this is defined at installation time and defaults to 5 minutes).
If an unauthorized user executes sudo, mail will be sent from the user to the local authorities (defined at installation time).
sudo was designed to log via the 4.3 BSD syslog(3) facility but can log to a file instead if so desired (or to both syslog and a file).
All preferences are defined at installation time and are derived from the options.h and pathnames.h include files as well as as well as the Makefile.

Top displays the top 15 processes on the system and periodically updates this information. Raw cpu percentage is used to rank the processes. If number is given, then the top number processes will be displayed instead of the default.
Top makes a distinction between terminals that support advanced capabilities and those that do not. This distinction affects the choice of defaults for certain options. In the remainder of this document, an "intelligent" terminal is one that supports cursor addressing, clear screen, and clear to end of line. Conversely, a "dumb" terminal is one that does not support such features. If the output of top is redirected to a file, it acts as if it were being run on a dumb terminal.
