What is the Dude

The Dude is a visual and easy to use network monitoring and management system designed to represent

network structure in one or more crosslinked graphical diagrams, allowing you to draw (includes automatic

network discovery tool) and monitor your network however complicated it might be. The Dude is capable of

monitoring particular services run on the network hosts, and alerting you about any changes in their status. It

can read statistics from the device monitored and show you graphs of the monitored values, allows you to

test and connect to the devices easily, and provides some very basic RouterOS configuration tools.

It is written in two parts:

Dude server is the actual program, which runs in background. It does not have any graphical interface,

and may only be controlled by a Dude client application located either on local machine, or anywhere

on the network. There is also a web interface to basic functionality, mostly designed as a quick and

accessible review tool, not a fullfledged configuration application.

Dude client may connect to the local or a remote Dude server, and is used as a graphical interface to it.

That means that every action is really executed on the server machine and the client is just showing

pictures. Thus, user window layouts are stored on the server and are not lost on disconnect.

System Requirements

RAM: minimum 64MB, recommended minimum 128MB

OS: Windows 2000/XP (does not work with Windows 95/98/Me) with Administrator permissions

Video: at least 800x600

Getting Started

When you first start the Dude client, it launches the local server and automatically connects to it. Then you

can disconnect and choose another server to connect to. You should remember that the client only works

when connected to an either local or remote server.

If you do not have any Dude server running yet, you should start it. There is a button on the top of the

application window called “Server”, which has indicator of whether the local server is running (it is green if

the local server is running). If you press it, a new window will appear that allows you to start/stop the local

Dude server, as well as completely reset its configuration.

When a server is started, you can connect to it pressing the Connect button. There are three connection

modes:

local – to connect to the local Dude server (note that this option will not work for Linux users running

the Dude under Wine, you should use remote connection to 127.0.0.1 host instead to connect to the

local Dude server)

remote – to connect insecurely (nothing, including passwords, is encrypted) to a remote Dude server

secure – to connect securely to a remote Dude server

Remote connection by default is using TCP 2210 port in regular mode or TCP 2211 port in secure mode, so

make sure these ports are not limited by a firewall. The ports may be changed in the server's Global Settings

menu. The default username for connecting to a server is “admin” with no password. You can change this

later.

Note for Linux users: you should start the Dude from the root user (or delegate some permissions to your

regular user), or else the Dude will not be able to ping hosts.

Graphical Interface

Dude Manual MikroTik Wiki

http://wiki.mikrotik.com/index.php?title=Dude_Manual&printable=yes

The interface has two panes. The first (left) pane is used to select a configuration section, and the second

(right) – to display the configuration window. At the top of the selection pane, there are five buttons:

Undo – reverse the previous configuration action

Redo – repeat an undone configuration change

Settings – configure global settings of the server, which will be described later on

Export export all the server configuration to an XML file

Import import the server configuration from an XML file

There is a network minimap at the bottom of the left pane, displaying a scaleddown view on the active map,

which can ease navigation on large network maps.

There may be many windows on the window pane. Each of them may be split in two either horizontally

(empty left half ; empty right half ), or vertically (empty top half ; empty bottom half ) using

buttons on the top of each internal window. By doubleclicking on an entry in the selection pane, the chosen

configuration window will be open on the top half of the window pane, zooming the existing windows of the

pane to the bottom half. Any configuration pane entry may be draggedanddropped onto an existing window

or selected with the dropdown list at the top of each window, and the chosen tool will replace the existing

contents of the window. The size of any window may be easily resized by moving its borders, in which case

all other windows will be zoomed accordingly.

Network Maps

The Dude is created to manage networks graphically, so the main interface to the program is the graphical

network representation, i.e. network map. You can instruct the program to detect all your network devices

automatically by specifying the IP address range it should scan. The Dude is capable of reading network

configuration of the devices that support SNMP protocol, and, thus, is able to make recursively scan the

networks connected to the already discovered network devices (up to the specified recursion level). It can

even detect “smart” switches and bridges that provide link information over SNMP. You may divide the

network into separate interlinked network maps.

There are two mouse cursor modes:

Grabbing tool – enables you to move the map by moving mouse cursor while holding left mouse

button pressed, instead of being required to move using scroll bars. Doubleclick opens device

properties.

Pointer tool – default cursor mode, when single mouse click selects an object. Moving cursor with

left mouse button pressed selects more than one object (if mouse button was pressed above the free

space on the map) or moves the selected object(s) (if mouse button was pressed on an object or a

group of them). Doubleclick opens device properties.

Left click on an object brings up a menu, where you can modify the object properties, as well as run device

tools. Mouse wheel is used to zoom in/out the map.

The maps are built with the following objects:

Device – network host with a unique IP address that runs one or more identifiable services, its

status may be monitored by.

Network – network cloud that represents one or more IP networks. It usually identifies a network

connection of a host (i.e., dedicated network interface of a network device) and represents OSI layer 2

interconnection between network devices.

Submap – wormhole to another network map. This is useful for splitting one big map into many

smaller and more readable ones. Doubleclicking on a submap link, will activate the map the link is

pointing to; if the target map has a reverse submap link, the map view will be centered on that.

Static – generic grouper of network hosts. You can link any object to this, without any effect

except that you will show that the objects are somehow connected.

Link – connection between two objects on a map, that represents OSI layer 1 physical link. It can

display traffic statistics if set to use SNMP protocol (in this case, you will need to specify the device

and the particular network interface to monitor). Depending on utilization, it may change its color,

signaling that the channel is almost full. There are various link types (styles), which represent different

kinds of links: VPN, wireless, etc.

Dependency – monitoring dependency. If a device depends on another, it is not monitored until

that, it depends on, is up.

On the map, you can select whether you want to see link diagram (all the network connections), or

dependency diagram.

When navigating through a map, if you leave the mouse cursor over a network object for about two seconds,

a tooltip will appear, showing some information on that object. Network devices will also have reachability

time graphs for each service (like ping time). Submaps will have the list of elements and a map preview

shown.

The map may be automatically aligned by pressing the “Layout button”. You can also align some selected

objects in line with the the automatic alignment tools:

Line tool – place the selected items in one line. First press the left mouse button at the beginning of

the line, release the mouse button at the end of the line.

Arc tool – align the selected items in an arc. First press the left mouse button at the starting point,

release the mouse button at the ending point. Then you can change the curvature by moving the mouse

cursor. Click once more to apply.

Device Representation

Each device is displayed as an icon related to a certain device type (fully customizable), which defines the list

of services a device should have to be classified to a particular type. The discovery procedure, when adding a

device, once detects all the services running on it, consults the device type table.

Each device has the table of all network services once found for the device. You can add and remove new

services from any device. The services are constantly monitored, and the ones failed to respond are marked in

this list. It is possible to configure a set of "parents" (dependency tree) for a device, so that the device is only

monitored if at least one of the parents is reachable. You can set polling preferences (polling frequency and

timeout for service probes) and select a notifier (procedure to undertake when the status of any probe is

changing, like open a popup window, beep, send an email or execute a program) for each device, as well as

for each particular service.

There is history, graphs and some SNMP information available as well.

Configuration

Global Settings

General

DNS: primary and secondary DNS servers to be used by the Dude server to resolve DNS domain

names.

SMTP: primary and secondary SMTP servers to be used by the Dude server to send out email.

The “From” email address should also be set.

SNMP: the default SNMP protocol settings

Polling: server default settings of how often (interval) to poll each service, and how long to wait for it

to respond (timeout), as well as choose the default notifier executed should a service fail.

Server

Dude remote: whether to accept remote connections, on which port to listen, and what networks

to allow to connect from

Web access: whether to accept remote connections via web interface, on which ports to listen

(HTTP and HTTPS protocols), and what networks to allow to connect from. Additionally, you

can change the information update frequency in clients' browsers (refresh interval) and the client

inactivity period, after which the web client would be considered logged off (session timeout).

Map Defaults (used when no specific settings are made for a particular map or a device)

Background color

Map object (device, network, submap, static, link, dependency) appearance: label and tooltip

contents, shape and font for an object. Some internal variables (like IP address) may be used in

label and tooltip contents, which may be selected out of the “Insert Variable” dropdown list. The

variables will be described later in this document.

Chart Appearance: background, grid, text colors, text style, line colors

Discover Defaults (used when no specific settings are made for a scan)

Black list: address list to exclude from scanning

Name Preference: which device name should be used. The discovery procedure may define the

device name by its IP address, DNS name or the string returned as the device name by SNMP

protocol. In this field you set, which one of thee names should be used. For example, if the field

is set to “DNS to SNMP to IP”, then DNS name will be used when available, if it is not, then

SNMPderived name will be used, but if neither of them are detected, then IP address will be
