Configure LANforge for Auxiliary Management.

1. Connect LANforge systems through the normal management LAN for initial configuration. The resources should be visible in the management tab

2. In this case, we are using wiphy0 for the Aux-Mgt interfaces. On the manager system, configure wiphy0 to be on the desired channel, create a virtual AP on wiphy0, and configure it appropriately. The Aux-Mgt checkbox should be selected, a static IP should be assigned, and an appropriate SSID configured. The AP Aux-Mgt port will automatically serve DHCP and will try to NAT and route packets to the wired Management interface.

3. On the other resources, configure the wlanX interface to connect to the AP on the manager system, and select the Aux-Mgt checkbox.

4. The Port-Mgr tab should look something like this when the Aux-Management interfaces are configured.

5. To test that it works properly, you can now remove the wired Manament port connection and wait about 1 minute for the old connection to time out and re-connect to the Auxiliary Management port. Or, just reboot systems with the wired ports unplugged and they should be discovered on the Aux-Mgt ports promptly.

Find the IP Address of the Windows PC. There are two methods you can use:

1. Using the Control Panel:

   1. Click Start, Run, control, [enter]

   2. Search and select Network Status and Devices

   3. We click on our device, Ethernet 3:

   4. Find and/or set the IP address: from Status, click Properites

   5. double click TCP/IPv4

   6. you will see and can change the IP address.:

2. Various DOS commands to find the IP addresses on the system:

   1. ipconfig and ipconfig /all

   2. netsh interface ipv4 show address

3. Resetting your DHCP address via command line:

   1. ipconfig /release

   2. ipconfig /renew

Find the MAC Address of the Windows PC. There are two methods you can use:

1. Method 1: use the Control Panel

   1. Click Start, Run, control, [enter]

   2. Search and select Network Status and Devices

   3. We click on our device, Ethernet 3:

   4. Click Details...

   5. Details will show the MAC address (physical address):

   6. (Suggested) Set the IP address if you have not already.

      For more information see Finding Windows IP Address

2. Method 2: use the DOS command-line. You want to correlate the IP address and MAC address of the Windows ethernet port:

   1. Click Start, Run, and type cmd, and press [Enter]

   2. Show interfaces by name with the command: netsh interface ipv4 show addresses

   3. (Optional) if you do not see results, you might need to start the network autodiscovery service: net start dot3svc

   4. (Optional) Depending on the edition of Windows, the command netsh lan show interfaces will display mac addresses.

   5. Show mac addresses with: getmac /v /fo csv
      _{(The CSV formatted command of the command ensures that we will see the entire name of the interface which can be trimmed short in the default output format.)}

   6. These commands will make it easier to copy using notepad:
      

      netsh interface ipv4 addresses > ifnotes.txt
      getmac /v /fo csv >>ifnotes.txt
      notepad ifnotes.txt

      

   7. Now you can easily copy the values:

Type in cmd and hit Enter

To get to your DOS window faster, you can pin it to your task bar. Right click the task bar CMD window icon and select Pin this program to taskbar

On the DOS window title bar, Right click and select the Defaults menu item

Select the Quick Edit Mode setting. This allows you to highlight text in the window easily.

In the Font tab, select a slimmer TrueType font, like Consolas or Lucida Console, and set the font size to 10

In the Layout tab, change the Window Size to 132 columns and 56 rows

If perl is installed correctly, you should have it in your path.

You can also use this technique to find any environment variable. E.G., find if you have a temporary directory set:

set | findstr /i temp

Configuring a PuTTY Session

1. When you double click on the PuTTY icon and it launches, you can start customizing your session preferences. We'll name this session jedtest

2. Let's default the window to something large, like 120 columns and 56 rows.

3. The Fixed font can be replaced with the Consolas font.

4. Let's turn on TCP Keep-alive and set IPv4 as the default networking protocol.

5. We login to LANforge resources with user lanforge

6. Generating a SSH keypair is not difficult. Let's enter the path to our public key file.

7. We have done our PuTTY config. Now back to the top Session screen, and click Save

Configure Pagent with your public key

1. Create your own public ssh key.

   For more information see WinScp Net

2. Start Pagent. Configure it to load on startup.

3. In the System Tray you will see the Pagent icon.

4. Right-click the Pagent icon and click Add Key to select your key

5. You will need to provide your pass-phrase to load your key

6. We see a loaded key

7. Here is our key, we will view the .pub file to copy out the public key.

8. In a putty window you will log into your LANforge server and edit /home/lanforge/.ssh/authorized_keys

9. Copy the text and place the "Comment" section at the end when you paste it into your ssh

10. Here is the public key string, with newlines and spaces removed. The Comment text goes at the end.

11. Check the permissions of the authorized_keys file. You might need to use the command

    chmod 600 authorized_keys

    to correct the permissions.

12. The next time we load the jedtest PuTTY session we should not be prompted for our password.

You want to install the windows version of the LANforge Server beforehand.
