Lab 1-1: Simple Network Hardware lab

In class, working in groups, we will build the following

GROUP:

Molly Natalie Lily (me)

Equipment:

• 1841 router will be an 1841 router!
• 2960 switches can be small Netgear switches for simplicity
• Laptop/server can be Foster Workstations booted to Kali Linux Thumbdrives

Connections:

Use ethernet cables to connect gear:

• Use Ethernet ports on the 1841 (and not the Serial ports)

---

Console into the 1841 using a USB console cable and Putty:

• Ensure the connecter to the 1841 to the computer is in the console port of the 1841

• Plug serial console cable (light blue) into USB port on Workstation

• Open Device Manager to see what COM port it is using:

COM3

• Connect cable to console port (also light blue) on router

• Power on switch (plug it in if not already running)

• Open Putty on Workstation

• Under Connection - Go to Serial and enter the following:

• Serial Line to Connect: COM port from Step 2

• • Bits per sec : 9600
• • Data bits : 8
• • Parity : none
• • Stop bits : 1
• • Flow control : none

• Under Session - Select Serial and change the COM port to the # from Step 2:

• Click Open - Hit Enter and you should have access!

---

Troubleshooting:

The router is stuck and will not recognize the commands needed

Solution:

Due to the router booting into read-only rommon mode:

rommon 1 > confreg 0x2102

rommon 2 > boot

Resources Used:

Subnet for Foster is 192.168.3.0/24

• Subnet for Skiff is 192.168.1.0/24

Configure appropriate IP's on the router FastEthernet Interfaces

Router> enable

Router# config t

Router (config)# do show interface

Router (config)# interface FastEthernet0/0

Router (config-if)# ip address 192.168.3.1 255.255.255.0

Router (config-if)# exit

Router (config)# interface FastEthernet0/1

Router (config-if)# ip address 192.168.1.1 255.255.255.0

Router (config)# copy run start

Configure appropriate IP's on the Laptop and server (Use Bootable Kali - see below)

Change IPv4 Config in Kali:

Computer One: 192.168.3.2

Computer Two: 192.168.1.2

Gateway/Router Interface: 192.168.3.1

Ping server from laptop

Take notes for your tech journal - we will be consoling into Cisco gear often!

Submit: screenshot of successful ping

Practice Saving Router config

Go back to Real-Time mode (clock)

From Router: Config Tab: Save NVRAM

Power Off Router- use power button

Power back on - Check router config to make sure Interface IP's are still there

Booting Classroom NUCS to Kali Linux

Plug the USB Thumbdrive into the powered off workstation

Hit the F10 key during the NUC Splash Screen

From the Boot Menu – Select UEFI Vendor Product Code 2

Select “Live System (amd64)” (first option) from the menu

That will take you into a Live Kali Linux desktop

If needed:

• Username: kali
• Password: kali
