NAME

grandvizier - DNSSEC-Tools dtrealms GUI

SYNOPSIS

grandvizier <realms-file>

DESCRIPTION

THIS NEEDS MAJOR EDITTING!!!

Warning: This is an early prototype. Consider it to be beta quality, if not alpha.

grandvizier is a GUI tool for use with monitoring and controlling the DNSSEC-Tools
dtrealms program. It displays information on the current state of the realms dtrealms is
managing. The user may control some aspects of dtrealms's execution using grandvizier
menu commands.

grandvizier creates a window in which to display information about each realms. (These
realms are those in dtrealms's current realms file.) For each realm, it displays the realm
name and the count of zones in each of these four states: normal, ZSK rollover, KSK
rollover, and KSK phase 6 wait state. As the rollover status of the zones in each realm
changes, grandvizier will update its display for that realm. Inactive realms, realms
listed in the realms file but which are not in currently being run, are displayed but have
no useful information to display.

The user may also hide realms from the display. These realms, if in the active state,
will continue to execute; however, their information will not be displayed. Display state
for each realm will persist across grandvizier executions.

Menu commands are available for some control over dtrealms. Display and execution options
for grandvizier are also available through menu commands. More information about the menu
commands is available in the MENU COMMANDS section.

grandvizier is only intended to be started by dtrealms, not directly by a user. There are
two ways to have dtrealms start grandvizier. First, realmctl may be given the -display
option. Second, the -display option may be given on dtrealms' command line.

OPTIONS

grandvizier takes the following options:

-display
Tells dtrealms to execute grandvizier as a child process.

-maxrealms
Tells grandvizier how many realms to display.

-Version
Displays the version information for grandvizier and the DNSSEC-Tools package.

-help
Displays a usage message and exits.

SCREEN LAYOUT

The grandvizier window is laid out as a series of "stripes". The top stripe contains
status information about dtrealms, the second stripe contains column headers, and the bulk
of the window consists of realm stripes. The list below provides more detail on the
contents of each stripe.

See the ROW COLORS section for a discussion of the colors used for the zone stripes.

· dtrealms information stripe

The information stripe contains five pieces of information: dtrealms's current realms
file, the count of rolling zones, the count of stopped zones, the count of zones to be
displayed, and the amount of time dtrealms waits between processing its queue.
Coincidentally, that last datum is also the amount of time between grandvizier screen
updates.

· column headers stripe

This stripe contains the column headers for the columns of each realm stripe.

· realm stripes

Each realm managed by dtrealms (i.e., every realm in the current realms file) will
have a realm stripe which describes that realm's current state. The stripe is divided
into two sections: realm identification and the realm's zone counts.

The realm identification section contains the name of the realm and the realm's
rollrec file.

The realm's zone counts section contains the number of zones in normal state, ZSK
rollover, KSK rollover, and KSK phase 6 wait state.

See the ROW COLORS section for a discussion of the colors used for the realm stripes.

ROW COLORS

The default grandvizier configuration displays each realm in its own row with a rotating
set of colors. The rows alternate with blue, red, and green, as defined in the X11
rgb.txt file. Row coloring can be turned off (and on) with configuration options and menu
commands.

MENU COMMANDS

A number of menu commands are available to control the behavior of grandvizier and to send
commands to dtrealms. These commands are discusses in this section.

File Menu
The commands in this menu are basic GUI commands.

· Halt Dtrealms

dtrealms's execution is halted immediately. As a result, grandvizier's execution will
also be halted.

· Quit

grandvizier will stop execution.

Options Menu
The commands in this menu control the appearance and behavior of grandvizier.

· Row Colors (toggle)

This menu item is a toggle to turn on or off the coloring of realm stripes. If row
coloring is turned off, realm stripes will all be the same color. If row coloring is
turned on, realm stripes will be displayed in varying colors. See the ROW COLORS
section for a discussion of row coloring.

· Inactive Realms Display (toggle)

This menu item is a toggle to turn on or off the display of inactive realms. If
display is turned off, realm stripes for inactive realms will not be displayed. If
display is turned on, realm stripes for all realms will be displayed.

· Modification Commands (toggle)

In some situations, it may be desirable to turn off grandvizier' ability to send
commands to dtrealms. This menu item is a toggle to turn on or off this ability.

· Font Size

This menu item allows selection of font size of text displayed in the main window.

Normally, changing the font size causes the window to grow and shrink as required.
However, on Mac OS X there seems to be a problem when the size selected increases the
window size to be greater than will fit on the screen. If the font size is
subsequently reduced, the window size does not shrink in response.

· Realms to Display

This menu item allows selection of the number of realms to be displayed in the main
window.

General Control Menu
The commands in this menu are GUI interfaces for the realmctl commands related to general
realm management.

· Stop Selected Realm

The selected realm will be moved to the inactive state. This only has an effect on
active realms.

A realm may be selected by clicking on its realm stripe. If this command is selected
without a realm having been selected, a dialog box is displayed from which a currently
active realm may be chosen.

· Stop All Realms

All realms will be moved to the inactive state. This has no effect on currently
inactive realms.

· Restart Selected Inactive Realm

The selected realm will be moved from the inactive state to the active state. The
realm will enter the active state at the same point from which it entered the inactive
state. This only has an effect on inactive realms.

A realm may be selected by clicking on its realm stripe. If this command is selected
without a realm having been selected, a dialog box is displayed from which a currently
inactive realm may be chosen.

· Restart All Stopped Realms

All realms will be moved from the inactive state to the roll state. The realms will
enter the roll state at the same point from which they entered the inactive state.
This has no effect on currently active realms.

· DS Published for All Zones in Selected Realm

This command is used to indicate that all the zones in KSK rollover phase 6 in the
selected realm have new DS records published by their parents. It moves all these
realms from KSK phase 6 to KSK phase 7. There is no effect on realms not in KSK
rollover phase 6.

Display Menu
The commands in this menu provide control over what is being displayed.

The realmstripe commands allow all, some, or none of the realm stripes to be displayed.
Undisplayed active realms will continue to be active, but they will do so without the
grandvizier window indicating this.

· Realm Selection

A dialog box is displayed that holds a list of the realms currently managed by
dtrealms. The user may select which realms should be displayed by clicking on the
realm's checkbox. Realms with a selected checkbox will be displayed; realms without a
selected checkbox will not be displayed.

· Refresh Display

Refresh the grandvizier display. The display will automatically refresh after a
certain number of updates; this command forces it to happen immediately upon
invocation.

Help Menu
The commands in this menu provide assistance to the user.

· Help

Display a window containing help information.

CONFIGURATION FILE

Several aspects of grandvizier' behavior may be controlled from configuration files.
Configuration value may be specified in the DNSSEC Tools configuration file or in a more
specific rc.grandvizier. The system-wide grandvizier configuration file is in the DNSSEC-
Tools configuration directory and is named grandvizier.conf. Multiple rc.grandvizier
files may exist on a system, but only the one in the directory in which grandvizier is
executed is used.

The following are the available configuration values:

colors Turn on/off use of colors on realm stripes.
fontsize The size of the font in the output window.
inactivecolor The background color used for inactive zones.
maxrealms The number of realms to display.
modify Turn on/off execution of dtrealms modification commands.
showinactive Turn on/off display of inactive zones.

The rc.grandvizier file is only searched for in the directory in which grandvizier is
executed. The potential problems inherent in this may cause these grandvizier-specific
configuration files to be removed in the future.

This file is in the "field value" format, where field specifies the output aspect and
value defines the value for that field. The following are the recognized fields:

Empty lines and comments are ignored. Comment lines are lines that start with an
octothorpe ('#').

Spaces are not allowed in the configuration values.

Choose your inactivecolors carefully. The only foreground color used is black, so your
background colors must work well with black.

REQUIREMENTS

grandvizier is implemented in Perl/Tk, so both Perl and Perl/Tk must be installed on your
system.

WARNINGS

grandvizier has several potential problems that must be taken into account.

development environment
grandvizier was developed and tested on a single-user system running X11 using a
relatively small number of zones. While it works fine in this environment, it has not
been run on a system with many users or in a situation where the system console hasn't
been in use by the grandvizier user.
