== Surfing the Network Topology ==
=== “Topology” Tab ===
Zenmap's “Topology” tab provides an interactive,    animated visualization of the connections between hosts on a    network. Hosts are shown as nodes on a graph that extends radially    from the center. Click and drag to pan the display, and use the    controls provided to zoom in and out. Click on a host and it becomes    the new center. The graph rearranges itself in a smooth animation to    reflect the new view of the network. Run a new scan and every new    host and network path will be added to the topology automatically.
The topology view is most useful when combined with Nmap's    <code>--traceroute</code>    option, because that's the option that discovers the network path to    a host. You can view a network inventory that doesn't have    traceroute information in the topology, but network paths will not    be visible. Remember, though, that you can add traceroute    information to a network inventory just by running another scan    thanks to Zenmap's scan    aggregation.
Initially the topology is shown from the point of view of localhost,    with you at the center. Click on a host to move it to the center and    see what the network looks like from its point of view.
The topology view is an adaptation of the    RadialNet    program by João Paulo    S. Medeiros.

|Each regular host in the network is represented by a little            circle. The color and size of the circle is determined by            the number of open ports on the host. The more open ports,            the larger the circle. A white circle represents an            intermediate host in a network path that was not port            scanned. If a host has fewer than three open ports, it will            be green; between three and six open ports, yellow; more            than six open ports, red.

|If a host is a router, switch, or wireless access point, it            is drawn with a square rather than a circle.
|-
|
|Network distance is shown as concentric gray rings. Each            additional ring signifies one more network hop from the            center host.
|-
|
|Connections between hosts are shown with colored lines.            Primary traceroute connections are shown with blue lines.            Alternate paths (paths between two hosts where a different            path already exists) are drawn in orange. Which path is            primary and which paths are alternates is arbitrary and            controlled by the order in which paths were recorded. The            thickness of a line is proportional to its round-trip time;            hosts with a higher RTT have a thicker line. Hosts with no            traceroute information are clustered around localhost,            connected with a dashed black line.
|-
|
|If there is no RTT for a hop (a missing traceroute entry),            the connection is shown with a blue dashed line and the            unknown host that makes the connection is shown with a blue            outline.

=== Controls ===
The controls appear in a column when the    “Controls” button is clicked. The controls are    divided into sections.
==== Action controls ====
The controls in the “Action” section control      what happens when you click on a host. The buttons in this section      are, from left to right, “Change focus”,      “Show information”, “Group      children”, and “Fill region”. When      the mode is “Change focus”, clicking on a      host rearranges the display to put the selected host at the      center. When the mode is “Show information”,      clicking on a host brings up a window with information about it.
When the mode is “Group children”, clicking a      host collapses into it all of its children—those nodes that      are farther from the center. When a host is grouped it appears      thus: .        Clicking on a grouped node ungroups it again. This diagram shows        the process of grouping.
Figure 12.7. Grouping a host's children
When the mode is “Fill region”, clicking a      host highlights the region of the display occupied by the host and      its children. The highlighted hosts are exactly the same as those      that would be grouped in “Group children”      mode. You can choose different colors to highlight different      regions. This diagram shows an example of several regions      highlighted in different colors.
Figure 12.8. Highlighting regions of the topology
==== Interpolation controls ====
The controls in the “Interpolation” section      control how quickly the animation proceeds when part of the graph      changes.
==== Layout controls ====
There are two options for the automatic layout of nodes. Symmetric      mode gives each subtree of a host an equal-sized slice of the      graph. It shows the network hierarchy well but hosts far from the      center can be squeezed close together. Weighted mode gives hosts      with more children a larger piece of the graph.
==== View controls ====
The checkboxes in the “View” section enable and      disable parts of the display. For example, disable      “hostname” to show only an IP address for each      host, or disable “address” to use no labels at      all. The “latency” option enables and disables      the display of the round-trip times to each host, as determined by      Nmap's <code>--traceroute</code> option. If      “slow in/out” is checked, the animation      will not be linear, but will go faster in the middle of the      animation and slower at the beginning and end.
The compass-like widget pans the screen in eight directions. Click      the center to return to the center host. The ring around the      outside controls the rotation of the entire graph.
“Zoom” and “Ring gap” both      control the overall size of the graph. “Zoom”      changes the size of everything—hosts, labels, connecting      lines. “Ring gap” just increases the spacing      between the concentric rings, keeping everything else the same      size. “Lower ring gap” gives a minimum spacing      for the rings, useful mainly when fisheye is enabled.
==== Fisheye controls ====
The fisheye controls give more space to a selected ring,      compressing all the others. The slider controls which ring gets      the most attention. The “interest factor” is      how many times greater the ring spacing is for the chosen ring      than it would be with no fisheye. The “spread      factor” ranges from −1 to 1. It controls      how many adjacent rings are expanded around the selected ring,      with higher numbers meaning more spread.
=== Keyboard Shortcuts ===
The topology display recognizes these keyboard shortcuts:
{| class="wikitable"
!Key
!Function
|-
|'''c'''
|Return the display to the center host.
|-
|'''a'''
|Show or hide host addresses.
|-
|'''h'''
