Cisco CCVP - 642-436-CBT NUGGETS

11:48 PM Shahbah No comments

This training provides the core knowledge of Voice over IP (VoIP) required for implementing and supporting data and voice integration solutions at the network level. It helps you grasp the VoIP vision, and to answer three major questions most companies have about VoIP solutions:

Why are so many companies moving to VoIP?
What are the benefits of using VoIP?
Is VoIP right for our company?

After helping you answer these questions, the CVOICE videos get into the nitty-gritty of VoIP implementation. They show you how to:

assign rules to nearly everything using Transformation Rules
move an existing PBX or Key System based network to the newer VoIP technology without getting rid of all your old equipment, so you can maximize the cost efficiency of your VoIP implementation
deploy a worldwide VoIP infrastructure, even using lower-end equipment.
configure your Cisco router to continually monitor the WAN line quality and dynamically change connections as necessary.
set up the Dial Plan that's best for your organization
understand and configure Gatekeeper
use VoIP to handle fax and modem

"CVOICE [Exam-Pack: 642-436 from CBT Nuggets] not only prepares you for the Cisco exam, but also has multiple practical VoIP deployment videos showing exactly how an administrator would set this up in the real world," explained instructor Jeremy Cioara.

The videos cover all objectives for the Cisco CVOICE exam 642-436, which is required for CCVP certification. A thorough understanding of Cisco networking such as CCNA or equivalent knowledge is recommended before viewing these videos. The training contains 33 videos providing more than 16 hours of instruction.

Remote Shell (rsh) configuration on Cisco Router

1:58 PM Shahbah No comments

Run remote commands on a Cisco router from your PC

Can you go to a Windows command prompt and run a command on your router? Usually, you would have to Telnet or SSH to the router first to run the command, right?
While this approach works, you can also run router commands without leaving the Windows command prompt, which can come in handy for scripting and automating router management. Let’s take a closer look.

What is remote shell (rsh)?

Remote shell (rsh) is a command-line program commonly found in UNIX and Linux systems. Using rsh, you can remotely execute command-line programs on a remote system. This could be another UNIX or Linux system, or it could be a Cisco router or switch. Rsh was part of the BSB UNIX operating system and included with rcp (remote copy) and rlogin (remote login).
While most Linux administrators are already familiar with rsh, some Windows administrators might not be. In fact, Windows XP and Windows Server 2003 both include rsh.

Figure A shows a screenshot of using rsh at the command prompt.

What is remote shell (rsh)?

However, when working with rsh, it’s important to remember that rsh is insecure — it does not encrypt the communications between the remote device and the system. You should always configure rsh as securely as possible on the router by locking down the IP address of the management machine and the username.
However, even when taking such precautions, rsh is still very insecure compared to SSH. It’s a good idea to use rsh only on a protected, secured, internal network. (By the way, if you’re allowing rsh through a firewall, it uses TCP port 514.)

How do I configure rsh on my router?

To be able to run a command on a Windows PC, have it go to the router, execute the command, and then return the output to you, all you need to do is enter two commands. Let’s walk through the process.
First, you need to enable the remote shell services on the router. The Cisco IOS calls the remote shell service ip rcmd. To enable this service, enter the following command when in Global Configuration Mode:

Router(config)# ip rcmd rsh-enable

Second, you need to configure the permissions for your workstation and your user to be able to perform these remote shell commands. Here’s an example of this command:

Router(config)# ip rcmd remote-host root 192.168.1.45 ddavis enable

Let’s take a closer look at this command. The ip rcmd remote-host part is required. Next, you enter the local username on this router of the user that the remote shell will log in under when it runs commands. In this case, we used the local user root.
Next, 192.168.1.45 is the IP address of the management workstation that we want to allow to execute these remote shell commands — in other words, the IP address of the PC. Next, you see my local Windows username: ddavis. In this case, that’s the name of the user logged into the Windows XP machine as well as the user who will be executing the rsh command in Windows. If I were running a batch job script that executed the Windows rsh command, I would need to enter the Windows username of the user that the batch job was running under.

Finally, the command contains the enable keyword. This allows the remote shell user access to enable the mode on the router. I could take this a step further and specify the level of access allowed (i.e., levels 1 through 15).
Keep in mind that these two commands assume you already have the router configured and you already have a local user called root. If you don’t have a root user, you can use the following command to do so:

Router(config)# username root privilege 15 password Cisco

How do I use rsh from my Windows workstation?

Once you’ve configured the above commands, you can easily run a remote shell command from the Windows command prompt. Figure B offers an example.

Figure B

Here’s the actual command I used:

Z: rsh Router1 -l root sh ver

Here’s how the command works:
•The hostname is the first thing specified (in this case, Router1).
•Next, I used -l (i.e., the letter L) to specify the remote username that I will use to log in. (Keep in mind that I still have to be user ddavis on the local Windows PC for the security to work. Also, I have to come from the IP address that I’ve specified — in other words, this wouldn’t work from another workstation.)
•Finally, specify the command. In this case, I ran the show version command (or sh ver).

What can I do with the rsh command?
In addition to using the show version command, you can also run the show running-configuration (sh run) command or any other privileged level command. Here are some more examples:

•show ip interface brief
•show ip route
•show ip ospf neighbors
•show ip bgp summary
•show log

What you can’t do is run a Global Configuration Mode command, such as enabling an interface or configuring an IP address. This usually limits you to the show commands.
However, one very useful thing you could do is copy your current configuration to a TFTP server and do it inside a script initiated on the Windows server. For example, you would use the copy running-configuration tftp:/1.1.1.1 command.

What else can I do with remote commands?

If you check out the Cisco IOS documentation that covers remote commands, you’ll find that there are a number of options you can use with the remote shell commands. One of the latest features in the Cisco IOS is that you can authenticate incoming rsh and rcp commands using a Cisco IOS access control list.
One of the more interesting variations is that you can use remote copy (rcp). So, I could copy a file using the Windows rcp command from my PC to the router or from the router to the PC — without ever using TFTP or FTP. (You can enable rcp with the ip rcmd rcp-enable command).

Windows Web Server-CBT Nuggets Video

12:54 AM Shahbah No comments

The Web server is the basis of everything that happens with your Web page, and yet often people know nothing about it. This CBT describes you how to build a Windows Web Server using Apache 2 and MySQL. Apache is one of the most popular Web servers on the Web right now, and part of its charm is that it's free. It also has a lot of features that make it very extensible and useful for many different types of Web sites. It is a server that is used for personal web pages up to enterprise level sites.We will also be discussing on how to use PHP in your web server to good effect.

Apache is possibly the world's most popular Web server. It is the most widely used and because it is released as "open source" and with no fee for use, it has had a lot of modifications and modules made for it. You can download the source code, and compile it for your machine, or you can download binary versions for many operating systems (like Windows, Solaris, Linux, OS/2, freebsd, and many more). There are many different add-ons for Apache, as well. The drawback to Apache is that there might not be as much immediate support for it as other commercial servers

Windows 2003 MCSE Simulator

12:07 AM Shahbah No comments

The Windows Server 2003 Simulator gives you the most realistic and sophisticated Windows Server 2003 simulation tool on the market today.

MCSE Lab Simulation Software offers rich, full-scale open Microsoft Windows Server 2003 simulations that allow users to view and practice network configuration and troubleshooting, and develop the necessary skills for the scenario-based MCSE exams, even if they don't have access to a network or software.

Open simulations for Microsoft Windows are critical to the training process. They replicate a real network system and let students execute the same job they can perform on the real system.

Open simulations allows MCSE students discover various answers for completing a task, and view the outcome of specific actions. Students learn through trial and error instead of being taught through specific instructions.
In addition, feedback at the end of each simulation task notifies the user to what was completed successfully and what was not.

Windows Server 2003 video demonstrations are designed to show students how to execute certain tasks using clearly defined steps. These videos are powerful instructional tools when combined with MCSE open simulation exercises.
These Windows Server scenarios require you to think through a difficult computing or administration problem. They are designed to help Microsoft MCSE students improve their troubleshooting skills.

Cisco PIX Remote Access VPN Configuration

11:55 PM Shahbah No comments

Cisco PIX (Private Internet eXchange) is a popular IP firewall and network address translation (NAT) appliance. It was one of the first products in this market segment.
In 2005, Cisco introduced the newer Adaptive Security Appliance (ASA), that inherited much of PIX features, and in 2008 announced PIX end-of-sale.

The PIX technology is still sold in a blade, the FireWall Services Module (FWSM), for the Cisco Catalyst 6500 switch series and the 7600 Router series.

The PIX was the first commercially available firewall product to introduce protocol specific filtering with the introduction of the "fixup" command. The PIX "fixup" capability allows the Firewall to apply additional security policies to connections identified as using specific protocols. Two protocols for which specific fixup behaviors were developed are DNS and SMTP. The DNS fixup originally implemented a very simple but effective security policy; it allowed just one DNS response from a DNS server on the Internet (known as outside interface) for each DNS request from a client on the protected (known as inside) interface. "Fixup" has been superseded by "Inspect" on later versions of PIX OS.

What is a WWAN ?

11:41 PM Shahbah No comments

A Wireless Wide Area Network or WWAN is wireless connectivity to the Internet achieved through using cellular tower technology. Cellular services like AT&T™, Verizon™ and Sprint™ offer WWAN for a monthly fee, or alternately on a pay-as-you-need-it basis. WWAN connectivity allows a user with a laptop and a WWAN card to surf the Internet, check email, or connect to a Virtual Private Network (VPN) from anywhere within the regional boundaries of cellular service

As people become more dependent on online technology to conduct business and keep information flowing, wireless connectivity has become a virtual necessity. Many hotels and communities offer local connectivity, but coverage is often spotty or nonexistent. WWAN can all but guarantee connectivity when you need it.
To take advantage of WWAN, a user must first purchase a WWAN PC card for his or her laptop unless WWAN connectivity is built-in. By purchasing the card and paying a monthly fee, one need only slip the card into the PC-card slot (formerly known as the PCMCIA slot) to access the WWAN. Plans vary among providers but most are rated according to data download caps, with unlimited plans running about $80 US Dollars (USD) per month. Data transfers of 5 Megabytes per month can start as low as $20 USD.
In some cases a person may not require 24/7 access to a WWAN, but would like to use it occasionally when free local networks are not available. In this case some WWAN providers will charge by the day for connectivity. By using the WWAN card, the user commits to a small charge, securing a 24-hour pass. At the end of the 24-hour period access to the WWAN is denied unless the user purchases another pass.
As an alternate to a WWAN card, it is possible to connect some cellular phones directly to a laptop using a Universal Serial Bus (USB) cable. The cell phone acts as a modem to patch the laptop into the Internet. This is only possible with certain cellphone models and plans, and the data transfer speed will be slower than connecting with a WWAN card. Before using this method, check with your cellular provider to see what charges (minutes) might apply, if any.

While there are certainly less expensive ways to get wireless connectivity in many cases, none cover the territory offered by WWAN for those visiting, living or working in remote or “nonwired” areas. WWAN is commonly available in regions where services like Digital Subscriber Line (DSL) and cable might not be. It can also be an international solution for global travelers, offering one more option for staying connected.
