Ah!! You are here, which means that you do want to know about me.
The name's Rubel & I live in BANGLADESH. Well, there isn't a biography of mine available, I'm not a celebrity.
However, I'm a GEEK, I live, breathe, sleep & talk INTERNET. This is my place on INTERNET & I'm happy with it. I love surfing INTERNET & getting to know good websites & believe me, though I've seen a lot of them, I'm still thirsty, b'coz, yeh dil mange more.
I am also complete the CCNA, CCNP, MCSA, MCDBA & MCSE certification. Now i am studying to sit the exam CCIE & RHCE.
Cisco Unified Communications Manager is an enterprise-class IP telephony call-processing system that provides traditional telephony features as well as advanced capabilities, such as mobility, presence, preference, and rich conferencing services. This powerful call processing solution can help:
* Simplify your voice systems by replacing old PBX (private branch exchange) and key systems with unified communications, you can cut costs and dramatically streamline provisioning and maintenance. * Build productivity with feature-rich unified communications that help workers spend less time chasing people, and more time being productive. * Enable mobility with software that has embedded unified mobility capabilities so mobile workers can remain productive wherever they are. * Improve collaboration with a click; start an IM session, initiate a phone call, and establish a videoconferencing call more easily.
Cisco Unified Communications Manager creates a unified workspace that supports a full range of communications features and applications with a solution that is highly:
* Scalable: Each Cisco Unified Communications Manager cluster can support up to 30,000 users. * Distributable: For scalability, redundancy, and load balancing. * Available: Support business continuity and improve collaboration with high availability that provides a foundation for multiple levels of server redundancy and survivability.
The CCIE certification is one of the highest paid and most respected IT certifications available but also one of the most difficult to obtain. Many people have questions and concerns when it comes to obtaining the CCIE and that's what this training is all about.
Jeremy Cioara has done a tremendous job breaking down all the information you need to not only study and prepare for the hands-on lab exam, but he presents it so that you learn how to model and configure advanced LAN/WAN topologies and scenarios. He shows you how to put together a practice lab to duplicate nearly any network set-up and provides an array of cost and time saving tips and tricks that will literally repay your investment in this training many times over.
Even if you do not plan on obtaining certification, you'll learn about the Catalyst 3550 router, Frame-Relay, ISDN, OSPF, ISIS, NAT, VoIP, QOS and BGP.
While a CCNP certification is not a pre-requisite to earn your CCIE certification, you do need to know routing and switching thoroughly. In addition to having a CCNA, we recommend that you have the knowledge and skills of a CCNP prior to viewing the CCIE videos.
The training contains 36 videos providing more than 24 hours of instruction.
NOTE: The CCIE Exam has been updated to cover new information on MPLS, as well as some additional information on Security and IPv6.
This training has not yet been updated to cover these concepts. This training still maps to all other exam objectives and will help you greatly as you prepare for the CCIE Lab exam.
For information on updates and future product releases, please see our Videos in Development page.

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
When Cisco first announced the Unified Communication Server (CallManager) would be based on Linux, my first question was “How much of the system would be available to users?”
I think it is great that Cisco does not require Engineers to understand the underlying system CallManager is built on, but some of us are curious. This tutorial will show you how to create a user on a CUCM 5/6 server with shell access and root privileges.
WARNING: This should not be performed on a Production System! I am not responsible for any destruction to production systems.
Boot the CUCM server with CentOS 5.1 Disk1
Type ‘linux rescue’ at the boot: prompt
Use the chroot command to change the root to the CUCM partition
Type 'chroot /mnt/sysimage'
Backup the /etc/passwd, /etc/group, /etc/shadow and /etc/gshadow files
cp -a /etc/passwd /etc/passwd.bak
cp -a /etc/group /etc/group.bak
cp -a /etc/shadow /etc/shadow.bak
cp -a /etc/gshadow /etc/gshadow.bak
These files are protected by the ext2 immutable flag. Check to see if the immutable flag is set. If the immutable flag is set, you will see an ‘i’.
A file server is a computer responsible for the storage and management of data in a central location. The specifications of a file server would normally consist of a large hard drive, a high CPU rate and decent amount of RAM. However, this may vary depending on the scale of how many requests the computer will be required to handle at once. Network clients can access these files, therefore saving them from having to physically transfer data from one computer to another. Users are able to access files and applications at the same time.
The administrator can configure the machine to be a dedicated file server; which would mean that the machine will only be used as a file server. Also, a non-dedicated file server; which would allow the file server to be used simultaneously as a workstation. File servers provide the ability to back up data with ease as everything is stored on one computer. Quotas can be set so that each user will have a certain amount of space on which he/she can save data.
