grandvizier — DNSSEC-Tools dtrealms GUI
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.
grandvizier takes the following options:
Tells dtrealms to execute grandvizier as a child process.
Tells grandvizier how many realms to display.
Displays the version information for grandvizier and the DNSSEC-Tools package.
Displays a usage message and exits.
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.
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.
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.
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.
The commands in this menu are basic GUI commands.
dtrealms's execution is halted immediately. As a result, grandvizier's execution will also be halted.
grandvizier will stop execution.
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.
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.
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.
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 the grandvizier display. The display will automatically refresh after a certain number of updates; this command forces it to happen immediately upon invocation.
The commands in this menu provide assistance to the user.
Display a window containing help information.
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.
grandvizier is implemented in Perl/Tk, so both Perl and Perl/Tk must be installed on your system.
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.
