Ubuntu Manpage: gspl-uchange - update or change user permissions

NAME

       gspl-uchange - update or change user permissions

SYNOPSIS

       gspl-uchange [ -options ] [ users ]

DESCRIPTION

       gspl-uchange may be used to update the user permissions file giving the user profiles of various users
       and the operations which they may be permitted to perform within the GNUspool system, together with the
       default permissions which are assigned by default to new GNUspool users.

       Further options allow for a "password dump" file to be maintained. This is for the benefit of NIS-type
       environments where reading through most of the password database can take an unacceptably long time, the
       user name and userid hash table is maintained in a file and updated as necessary.

       The invoking user must have edit admin file permission.

OPTIONS

Note that the order of treatment, letters and keywords described below may be modified by editing the
file rest.help - see spsyntax(5). The environment variable on which options are supplied is
"GSPL-UCHANGE" and the environment variable to specify the help file is "SPRESTCONF".

-? or +explain
causes a summary of the other options to be displayed without taking further action.

-A or +copy-defaults
copy the default profile to all users before setting other permissions on the named users (with the
-u option) or after setting the defaults (with the -D option).

The privileges of the invoking user are not changed by this operation.

-c classcode or +class classcode
set the class code of the user(s) as specified by the argument.

-D or +set-defaults
indicate that the other options are to apply to the default profile for new users.

-d num or +default-priority num
set the default job priority to num, which must be between 1 and 255.

-F pattern or +form-allowed pattern
set the permitted form types to match pattern.

-f formtype or +default-form formtype
set the default form type to formtype.

-l num or +min-priority num
set the minimum job priority to num, which must be between 1 and 255.

-m num or +max-priority num
set the maximum job priority to num, which must be between 1 and 255.

-N or +no-rebuild
cancel the -R option.

-n num or +max-copies num
set the maximum number of copies to num, which must be between 1 and 255.

-O pattern or +ptr-allowed pattern
set the permitted printers to match pattern.

-o printer or +default-ptr printer
set the default printer to printer.

-p privileges or +privileges privileges
set the privileges of the user(s) as specified by the argument.

-R or +rebuild-file
rebuild the user permissions file spufile0 incorporating any changes in the password list.

-s or +no-copy-defaults
cancel the effect of the -A option

-u or +set-users
indicate that the other options are to apply to the users specified on the rest of the command line.

-X or +dump-passwd
dump out the hash table of the password file to avoid re-reading the password file within the other
programs.

-Y or +default-passwd
default handling of password hash file dump - rebuild if it is already present and -R specified,
otherwise not.

-Z or +kill-dump-passwd
delete any existing dumped password hash file.

+freeze-current
Save all the current options in a .gnuspool file in the current directory.

+freeze-home
Save all the current options in a .gnuspool file in the user's home directory.

Users or default

       In one operation gspl-uchange either adjusts the default permissions, to be applied to new users,  if  -D
       is specified, or specified users, if nothing or -u is specified. So first set the required defaults:

               gspl-uchange -D -n 20 -p Form,Prinq,Hgo,Cdef -A

       Then set named users

               gspl-uchange -p ALL jmc root spooler

Rebuilding the user control file

       After adding new users to the system, you should rebuild the user control file by running

               gspl-uchange -R

       On a system with a large number of users, this can take a long time, so the previous method of adding new
       users  as  they  were  encountered  meant  that  various  hold-ups  occurred in standard utilities or the
       scheduler, whichever was the first to "notice" the changes, which might, in the event, be half-complete.

       We suggest that this command be added to the "add new user" procedure for your installation.

Dumping the password file

When any of the GNUspool programs which may require to map numeric user ids to names and vice versa
start, one of the first operations is to build the appropriate hash tables. This may take some time if
there are a large number of user names, especially if NIS (a.k.a. yellow pages) is in use.

A short cut is to dump out the password file into a hash table file, by default pwdump0, which may be
quickly read in by the relevant programs instead of rebuilding the hash table each time.

You may opt to create the dumped password file by running

gspl-uchange -X

This should only be done when all GNUspool programs are stopped.

Afterwards, each time the user control file is rebuilt using the -R option (or equivalents in other
programs such as gspl-user(1)), this file will also be rebuilt. -X does not have to be specified again.

If you ever decide you want to dispense with this file, run gspl-uchange with the -Z option.

For completeness, the -Y option is provided to cancel -X or -Z in case they are provided in the
environment or a .gnuspool file, an extremely bad idea.

Privileges
The following may be specified as the argument to -p, as one or more (comma-separated) of the following
codes, optionally preceded by a minus to turn off the corresponding privilege. These codes are the same
as those displayed by gspl-ulist(1).

Gspl-uchange disregards the case of the codes entered.

Adm edit admin file

Stp stop scheduler

Form select forms other than restriction pattern

Otherp select printers other than restriction pattern

Cpri change priority once queued

Otherj edit other users' jobs.

Prinq select printer list

Hgo stop and start printers

Anyp select any priority once queued

Cdef change own default priority within range

Addp add and delete printers

Cover override class

Unq unqueue jobs

Votj view (but not change) other users' jobs

Remj access remote jobs

Remp access remote printers

Accessj access non-displayed job attributes

Freeze freeze parameters from display

"ALL" may be used to denote all of the permissions. For example:

-p Otherj,Otherp
-p ALL,-Adm

Notice how "ALL" is set first and then "Adm" taken away in the second example.

A hexadecimal value is also accepted, but this is intended only for the benefit of the installation
routines.
