4.1 Menu, Tool Bar and Status Bar
(All) denontes that the operation will be
applied to all sniffers or replayers if the shift key is
held down while the operation is selected (but note that, for this to
work on the menu, the shift key must be pressed before the menu
is traversed - this is a bug).
The Monitor Menu
The Monitor menu contains common operations
relating to the creation, deletion and execution of sniffers, and
replaying log files. Note that most of these operations are also
available on the toolbar.
New Sniffer
This creates a new sniffer. The new sniffer
will be named Sniffer N where N is a number that
distinguishes it from all other sniffers, however this can
be changed if desired. The new sniffer starts with a default,
essentially empty, configuration.
New Remote
This creates a new remote sniffer. You
will be prompted for the host on which the remte sniffer should
run, the port with which the remote sniffer is associated, and a
password. For information on setting up a remote sniffer
click here.
New Replay
This creates a new replayer that can
be used to replay an earlier binary log file. The new replayer
is named Replay N in a similar manner to a new sniffer.
The replayer also starts with an essentially empty
configuration.
Close
The currently selected sniffer or replayer
is closed. This will stop any activity associated with the monitor
or replayobject, particulary an active packet filter.
Run (all)
(All) sniffers and replayers that
are not currently running are started. That is, sniffers will
start to monitor the network, while replayers will start
replaying their associated log files. Note that individual
sniffers and replayers can be controlled from their
configuration windows.
Halt (all)
(All) running sniffers and replayers are stopped.
In the case of sniffers, packet capture and filtering
is stopped.
Freeze (all)
The freeze operation freezes the graphic and
packet displays for (all) active sniffers and replayers.
Note that the monitoring or replay continues, so that when they are
resumed the graphic and packet display will immediately advance to
the current time.
Resume (all)
This function resumes (all) frozen sniffers and
replayers, as described above.
Save
The save function saves the configuration of all sniffers,
to be reloaded the next time that KSnuffle is started. Note,
however, that when KSnuffle is next started, the sniffers
are all stopped, irrespective of their state at the time of the
Save. Also, no information is saved for extant replayers.
- Save and Exit
Configuration information is saved as above, and the program exits.
Exit
The program exits without saving any configuration information.
Sniffers
Display the currently selected sniffer or replayer.
Parallel
Use this item to display a page which contains up to four parallel
load histograms, allowing visual comparisom of network loading for
different packet filtering settings.
Global Setup
The setup page contains various global setup options.
Privileged User Setup
This page contains the privileged user configuration options.
Note that this icon, and the corresponding page, are only
present if KSnuffle is running as root.
The View Menu
The View menu contains functions that control
the display or otherwise of various components of KSnuffle.
- Toolbar
This item toggles the display of the tool bar.
- Statusbar
This item toggles the display of the status bar.
Configuration
Each sniffer or replayer has three display pages for
configuration, plus graphic load display, and packet display. This
item selects the main configuration page. Note that if the parallel
graph or global setup page is on display, then display switches back
to the sniffer or replayer.
Filter/triggers
Display the filter and trigger page, similarly to the configuration
above.
Event commands
Display the event commands page, similarly to the configuration
above.
Graphic display
Display the graphic page, similarly to the configuration above.
Packet monitor
Display the packet display, similarly to the configuration above.
Sniffers
Display the currently selected sniffer or replayer.
Parallel
Use this item to display a page which contains
up to four parallel load histograms, allowing visual comparisom
of network loading for different packet filtering settings.
Global Setup
The setup page contains various global setup options.
Privileged User Setup
This page contains the privileged user configuration options.
Note that this icon, and the corresponding page, are only
present if KSnuffle is running as root.
At the bottom of the view menu will appear entries for each
sniffer or replayer currently in existence. Selecting
one of these will display the corresponding monitor.
The Tool Bar
As well as various shortcut buttons corresponding to menu functions,
the toolbar also contains a combobox which can be used to select
between current sniffers and replayers.
For the Run, Halt, Freeze amd Resume
buttons, the shift key applies the operation to all sniffers
and replayers, as for the corresponding menu items.
The Status Bar
The status displays:
-
The state of the currently selected sniffer or
replayer. This is one of:
- Unset - No configuration set
- Set - Configuration set
- Reset - Configuration reset
- Running - sniffer or replayer is running
- Waiting - Waiting for trigger
- Halted - Halted after stop trigger
- Error - Error, should not appear
-
Whether the currently displayed sniffer or replayer
is frozen.
-
Whether the packet display for the currently displayed sniffer
is paused.
-
The first load average for the currently selected
sniffer or replayer.
-
The Second load average for the currently selected
sniffer or replayer.
-
Internal memory usage: this gives some idea of the amount of
memory that KSnuffle is using to store packet and other
information, such as nameserver lookups and TCP/IP stream
data.
