Microsoft Windows Server 2012 – iSCSI LUN Configuration

June 17, 2013
iSCSIStorage Area Network

You may use the following method to add storage disks, from an iSCSI SAN, to a server running the Microsoft Windows Server 2012 operating system (OS). All of the configuration will be completed from the operating system so this post assumes that the iSCSI initiator service is running and has been properly configured. Additionally, this post assumes that the SAN has been properly configured (volume, iSCSI IQN, LUN masking, etc.).

Begin by right clicking the Start menu and selecting Disk Management.

00

 

Next, right click the LUN that was configured on the SAN and select Online.

01

 

Next, right click the LUN that was brought Online and select New Simple Volume.

02

 

On the Welcome to the New Simple Volume Wizard page click Next >.

03

 

 

 

 

 

 

 

 

 

 

On the Specify Volume Size windows specify the size of the volume and click Next >. In this example it is 50 GB.

04

 

 

 

 

 

 

 

 

 

 

On the Assign Driver Letter or Path page you may assign a drive letter, use the LUN as an NTFS mounted drive or choose not to any assign any drive letter. In this example I will use the drive letter I.

05
 

 

 

 

 

 

 

On the Format Partition page keep the default values and click Next >.

On the Completing the New Simple Volume Wizard page verify the configuration and click Next >.

06

 

Lastly, on the Disk Management console you may see that the iSCSI disk is now available for use by the Windows Server 2012 operating system.

Cisco – Initial Router Configuration

June 13, 2013
CiscoNetworkRIP

You may use the following commands to configure a Cisco router out-of-box. The diagram below will provide you with a visual of the network topology. There are two (2) routers in this configuration utilizing the Internet Protocol (IP) addresses 172.16.25.1/30 and 172.16.25.2/30. I chose a subnet mask of 255.255.255.252 (/30) for the Wide Area Network (WAN) links because this link will only utilize two (2) IP addresses and the 255.255.255.252 subnet mask allows us to save IP addresses.

Network Topology

 

For the first step of the configuration I will verify that the router has no previous configuration by executing the show running-config and show startup-config commands. You may verify that this is a freshly restarted router with no previous configuration.

00

 

In the second step I will configure the user mode passwords (aux, console and vty), as well as the idle timeouts and a command to stop any router output from disrupting your text. The idea behind these first few configurations is to immediately secure the router.

01

 

Next, I will configure the enable mode password with the enable secret password command.

02

 

Next, I will configure the hostname of the router. In this example the hostname chosen is ORLSAN01.

03

 

Next, I will configure the message of the day (motd), login and exec process creation banner. These provide a warning to any individuals who would seek to login to the router without proper authorization.

04

 

08

Next, I will configure the Serial 0 and Ethernet 0 interfaces. Additionally, the Serial 0 interface will have the clock rate set in order to providing clocking to the second router in the network topology above. In a production environment this would not be necessary but for this demonstration it is.

05

 

09

Next, I will verify that the routing table only contains directly connected networks (no remote networks). Additionally, I will verify that pinging 172.16.30.1/24 will not work because there is no routing table entry for that network. In later configurations we will configure both static and dynamic routing.

0610

Next, I will save the configuration to NVRAM.

07

 

 

In the next portion of this demonstration I will configure the second router (ORLSAN02) but instead of showing all of the output I will only provide the final configuration via show running-config (with the hope of saving space).

11

 

From the show running-config you can see that the passwords are in clear text. By using the command service password-encryption and executing the show running-config command you can encrypt the passwords.

 

12


1314

Next, I will verify that the routing table on ORLSAN01 still only has directly connected routes (so the ping to 172.16.30.1/24 will fail).

15

Next, I will configure a static route to the 172.16.30.0/24 network and verify that the route is in the routing table. I chose an administrative distance of (AD) of 150 because these static routes will be a backup in the event that dynamic routing, to be configured later, fails. The S in the routing table signifies that the route is a static route, the C means the route is directly connected. If you ever see an R that means it is a RIP injected route.
16 Next, I will configure ORLSAN02 with a static route to the 172.16.20.0/24 network, verify the route is in the routing table then ping 172.16.20.1.

17

Lastly, I will configure dynamic routing (RIPv2) on both routers, then verify that the RIP injected routes on ORLSAN01 and test the configuration by pinging 172.16.30.1 from the ORLSAN01 router.

Microsoft Windows 7 – Modifying Profiles for Shortcuts, Folders or Files

June 11, 2013
Microsoft Group Policy Object

You may use the following method, in Microsoft Windows 7, to modify the default profile and create changes in every users profile. For instance, you may add a particular shortcut, folder or file to the desktop of every single user. In Windows 7 navigate to:

C:\Users\Default\Desktop

Once you are in this directory you may place the shortcut, folder or file. Once the modification is complete any user who logs onto the computer, and creates a profile, will receive that shortcut, folder or file.

Additionally, you may use a group policy object (GPO) as an alternative solution if you have several users who need this shortcut, folder or file.

Cisco – Configuring Cisco WRVS4400N Router

June 6, 2013
CiscoNetworkWireless Networking

At my current employer we recently had a Cisco Small Business WRVS4400N Wireless-N gigabit security router with VPN reach the end of it’s life. I replaced the wireless access point and configured it using the documentation I created in the past. Below you will find a basic step by step guide for configuring the device as a wireless access point.

NOTE: Please keep in mind that this is a very basic configuration and your configuration should be planned with careful considering to your Information Technology (IT) infrastructure. Additionally, I have modified the input of the actual configuration for security purposes.

1. The default Internet Protocol (IP) of the device is 192.168.1.1/24. You may manually configure the IP address of a Windows host to 192.168.1.2/24 in order to connect to the device. The default username is admin and the default password is admin.

00

 

2. Upon logging into the device you will see the following web page.

01

 

3. Navigate to the Administration > Management page and configure the Router Username: and Router Password:. It is widely considered a best practice to change the default username and password in order to prevent unauthorized users from logging into the device.

02

 

4. Navigate to the Setup > LAN page and configure the Local IP Address: and Subnet Mask: of the device. In our environment we have an existing Dynamic Host Configuration Protocol (DHCP) server so the DHCP Server: settings under the Server Settings (DHCP) menu is configured as a DHCP Relay.

03

5. Navigate to the Setup > Time page and configure the time settings for the device. I chose to use the Set the local time using Network Time Protocol (NTP) automatically setting. Our Time Zone: setting is (GMT-05:00) Eastern Time (US & Canada).

04

6. Under the Wireless > Basic Settings page configure the Wireless Network Mode:, Wireless Channel: and the SSID settings.

05

7. Under the Wireless > Security Settings page configure the Security Mode: and Shared Secret: for the SSID configured in step 6.

06

8. I recommend you backup the configuration by navigating to Administration > Backup & Restore. Once you are redirected to this page click the Backup button and specify the directory where the backup configuration will be saved. I did have a previously saved backup configuration but I configured this Cisco wireless access point manually in order to document the process on this webpage.
