Setting up The Dude

The Dude

The Dude is a great (and free) way of monitoring your network. It has two parts, The Dude client and RouterOS server. A VM will be running RouterOS on our Hyper-visor and be constantly monitoring the network, while The Dude will run on our machine and tell us all the info from the server.

Installing RouterOS

Go here and download the RouterOS VHDX and The Dude Client.
Copy the RouterOS VHDX to your Hyper-V server in the hard drives folder.
Create a new VM with 512MB RAM and use the VHDX as hard drive.
Boot the VM, connect, and log in with -> Username: admin Password: [blank]
At the terminal, enter the follow commands:
1. /ip address remove 0
2. /ip address add address=[static ip]/[CIDR subnet] broadcast=[default gateway ip] interface=ether1
3. /dude set enabled=yes
The VM is now set up.

Example of Step 5.2:

Get get the following settings:

IP Address: 10.1.1.36

Subnet Mask: 255.255.255.0 (/24)

Default gateway: 10.1.1.1

Use: /ip address add address=10.1.1.36/24 broardcast=10.1.1.1 interface=ether1

Installing The Dude

Run The Dude installer.
After it's done, start up the client and enter the IP address you set for the RouterOS VM.
It should prompt you to enter device discovery settings, after which it will discover all connected devices on the network. There will be a lot of devices.
You should turn off auto scan by going to Settings (above the main area) -> auto scan -> select the only entry -> delete
Now you can start organising your network map.

Notes

Changing the default admin password

The default user/pass is admin/[blank] which is not so secure, so it's best if you change it with the following command:

/user set admin password=[new password]

To logout

/quit

Show IP Address

/ip address print

SNMP

Snmp is a protocol that the dude uses to find out inforamtion from switches and other devices. Things such as what interfaces they have and their current data rates. This is super useful for finding out where all your data is going...BUT FIRST...SNMP needs to be enabled. Here are a few pointers to get SNMP working on your network.

Cisco Switchs

Some useful commands:

show snmp

To enable snmp from CLI:

enable
configure terminal
snmp-server community public ro
end
copy running-config startup-config

In the dude map, you may need to change cisco switches Snmp Profile property to v2-public (ie Snmp v2c) other wise they will not populate the information as they should.
