Ubuntu Manpage: grandvizier - DNSSEC-Tools dtrealms GUI

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.
