A Detailed Review On NAS Server

Posted on 10th May 2012 in Back-up Nas

What is this NAS Server? This is a major question being asked these days. NAS Server is an abbreviation of Network Access Storage Server. This server was actually made by an inspiration from Newcastle Connection which was invented in late 19 century by a brilliant student of Newcastle University. In 2000 many great companies made different file servers but 3Com was the first come who invented this NAS Server for all desktop applications. After this invention many other new versions were introduced to market and these versions tried to take place of the original one unfortunately this could not happen.

This was the history of the NAS Server let me tell you little about this NAS, Network Access Storage is a small unit or device that is connected to a computer which helps the computer to share file or store files on it for a little moment but once these files are accessed or used they are destroyed after words.

If I explain this process in practical terms than its like this that in big organizations or multinational organizations a printer is placed a corner place of the department and almost every employee there can access that printer. Usually one printer could be connected with one system at the moment but here that printer is connected with several, here a small server is used called print server. This print server helps to pass on the documents to the printer and make a proper queue of the documents and  as every system has its own code when that code is given to the printer prints out exactly that document which was sent to it by the system having that regarding code. This whole technology or the method is derived from the NAS Server technology, in the similar way the NAS server send the file and store the file there on it so that the file could be accessed any moment.

AS the Print server has a little keypad attached to the printer but the NAS server doesn’t have any kind of display panel or any keyboard attached to it, it is directly control through the browser of the system.

As the NAS server is a server and from its name it’s understandable that a server usually have a big size hard disk as compared to local computers. So it has more than one or two hard disk and the system that is specially used to control the NAS server also doesn’t have a fully furnished operating system on it rather the system is stripped according to the needed items.

There are different uses of this NAS server like usually it is to provide space to the clients so that they can easily store their files when they want. These NAS Servers are good enough for the bank as these days the trend of online banking is increasing a lot. Other than the customer use bank’s employees also sometimes need to get information from other bank branches and this is the perfectly easy way to access data.

Small Business Server Backup testimonial from a recent Dependable Computer Guys, Inc. client, in a testimonial from the citisearch website.

Dependable SafeSTOR saved the day! Testimonial by BethJenkins via Citysearch

“We would have been completely shut down if it hadn’t been for not only the Dependable SafeStor device, but the quick access we had to a technician at Dependable Computer Guys! And, this was on New Years Eve! I highly recommend Dependable Computer Guys and even more importantly, the Dependable SafeStor service.”

“I have worked with Dependable Computer Guys for a number of years now. They have done an excellent job handling all of the IT needs of our company. The most important service they have provided is Dependable SafeStor. We went onto the SafeStor service in December. Just a few weeks after starting, our computer server failed. We were unable to function at all. I called Dependable Computer Guys and within 20 minutes, remotely, they were able to switch us over to the SafeStor device and we were completely operational. We were able to be up and running while our server problem was diagnosed, the parts were ordered and the repair made.

My Experience With Ftp Server

Posted on 24th March 2012 in Ftp Backup

Lets start with my experience on FTP server for Linux. To start configuring FTP on a linux machine, the discussion would be helpful to you. Once we planned a FTP server solution for employees to help them sharing documents with other employees inside intranet and those who were working remotely and our partners. So what I did, went to the server setting of my Redhat Server and updated installation for vsftpd service, the daemon or self invoking process that runs FTP on the server. It asked for the Redhat CD and I entered it inside CD ROM. Once the vsftpd installation was finished from server settings window. After the installation of vsftpd, I started the service using command service vsftpd start on the linux terminal or command line interface. And checked the status of the service by using service vsftpd status command. The service was running successfully. I went to the address bar and checked ftp://localhost and shown me some public folder of the FTP server. I went to the configuration file for vsftpd service called vsftpd.conf and edited it for anonymous connections and disallowed them by selecting NO. Now what I required was FTP accounts for my users. So I went to System>>Administration>>Users & Groups and created few users and put them into FTP group. Then I went to some other client on the network which was my Lenovo Laptop and tried to access FTP Server running on my linux box. I typed the IP address of the linux machine on my windows explorer address bar using ftp protocol ie ftp://192.168.1.5 and waited for the FTP server folder to browse and ask for username and password. But guess what, nothing happened. I went to my server and disabled my firewall called iptables running on the ftp service. Again tested , again failed as I need to FTP access within LAN network on my Gateway Security Device, called ZyWALL or network firewall. Tested again and this time I was successful in getting the screen asking for username and password. I entered the username and password, I created for my self and finally got the folder, that was created by in /home diectory while creating user. The problem I faced was during browsing files using FTP client like Core FTP on my laptop. While browsing /home/puneet folder, I was not restricted to it and can go to home and / folders easily and see the files of other users inside the home directory. This was a challenge for me. So I went into my CLI on redhat box and checked for file etc/vsftpd/chroot.list and added my usernames to the file(each at next line) to restrict them to entered directories of other users or home directory. In fact I have jailed them inside their own directory and no command would change their directory while browsing and connecting from FTP clients like FileZilla, Core FTP or Cute FTP or SFTP. Later I mapped private IP 192.168.1.5 to static public IP address, that was running on the 2nd WAN port of my Security Gateway. My server was connected to the port that was under the DMZ zone to keep it separate from my LAN network. I created 1 to 1 NAT mapping (192.168.1.5 59.x.x.x). Let me remind that both my server and client were running on different subnets. My client IP address was 192.168.100.5. After mapping private IP to the public IP address for port 21, I allowed WAN to LAN connections through my firewall to publish FTP to my outside employees and partners. Assigned a subdomain ftp.domain.com to my public IP for FTP from my website control panel A records to make FTP server access easy using domain name. Now everybody was able to access FTP server with ftp://ftp.extranetworld.com and by entering therir username and passwords with a Read/Write Acces to their home user /home/user directory. We managed all other configuration from vsftpd.conf like allowing chroot users. It might be possible, if the people sitting inside same LAN network where server is hosted might not access FTP server with public IP. To solve that you need to an entry to your Gateway FQDN for opening LAN IP address for ftp.extranetworld.com . Its the easy way. Other way could be to keep your server and LAN at different public IP’s. NAT loopback is also another way to access server running on internal network with mapped public IP, and the rule automatically created while setting up vitual server rules in Security Gateway device. I have done lot of RnD on it and taken help from my friends and have also taken help from my friends Gurnek Singh Thiara and Moh. Adeel for setting up intranet FTP successfully for extranetworld.com.

Microsoft Sql Server Reporting Services (ssrs)

Posted on 1st March 2012 in Intermezzo

SQL Server Reporting Services (SSRS) is a report generation software system of Microsoft in Server-Side. It is using to variety of interactive and useful reports. It is generated with the help of Login-Id and Pass on web based Interface. Its main is RS with the help of web based interface to support the development of custom reporting applications.
Parameters in Microsoft SQL Server 2000:
There are so many types of parameters but some of the most useful to know are:
1: Selecting all or one item from a list First Create a Data set to return @Parameter A: SELECT DISTINCT Name FROM Organization Name UNION SELECT ‘.All’ AS Name ORDER BY A
Then the main data set add to the front IF @Parameter = ‘.All’ SELECT And after the SQL, add ELSE and repeat the SQL
2: Selecting the hour and Minutes or hour, Minutes and seconds. For this a set of Datasets where one is filtered by the other, provides the final Parameters for your main data. Dataset Called Hour select distinct hour (date) as hour from Times order by 1 DESC Note how this is sorted in descending order. This is so the latest hour (parameter) is displayed. Also note, is one of the columns returned in another dataset is also hour, then reporting services will return an error. Change the name of the data set to fix this.
Reporting Services with Web Services:
The Reporting Services behalf of Web service is an Extensible Markup Language (XML) Web service with a Simple Object Access Protocol (SOAP) API.
If we will use the RS with web service so it improves the functionality of this services
to your business applications. Web Service interface provides a set of rendering and viewing functions during URL access, yet web based services also provides a additional functionality of managing the contents of a report server with the help of vital set of web methods.
In the case of reports management, subscriptions, schedules, data sources, and other Report Server items is a requirement. For the Report server, web service provides a single entry point to the full functionality of Report managements. It is quite easy to develop applications that take advantage of the web services using Visual Studio.Net or any other SOAP-enabled development tools.
Benefits of SQL Server Reporting:
1: Create applications to manage one or more report servers through the Web services interface.
2: Create additional rendering, delivery, and data processing extensions using the Microsoft.NET Framework.
3: Create applications that generate reports using the Report Definition Language (RDL).
4: Create applications that embed or link to a Web browser to present and manipulate report output through URLs.

OLAP Server for multi-dimensional queries

Posted on 14th February 2012 in Intermezzo

OLAP Server supports multi dimensional query language and it can process vast queries by analyzing the queries also. It reads data and stores in the memory cache. Basically the modern trend is multidimensional data analysis such as OLAP analysis. OLAP server evaluates large volume of historical data. Business intelligence includes OLAP cubes, data warehouse, data mining etc. Basically user can store, process, and analyze huge volume of historical data. The data are multidimensional in nature. They contain relational models.

Multidimensional structure is defined as a different relational model which uses multidimensional structures to manage data and describe the relation between the data. The structure is divided into cube and it stores and accesses data within the border of the cube.

Each cell contains total data which is related to elements and its dimensions. If the data is tampered still then it is possible to access the database as is a compact type of database. Data are related to each other. In the analytical database multidimensional structure is popular because of the use of the OLAP (Online Analytical Processing). Actually analytical databases are very popular because they can answer the business queries very quickly. In this database data are viewable from the different angles which give a broader outlook of a query. This is not possible in other models.

It is claimed that an OLAP cube can process a business complex query in 0.1% of the time which an OLTP relational data takes. The important feature of the OLAP is to process complex business queries very fast.

It works by aggregating huge business complex queries. It is done from the data of the fact table. It is done on specific dimensions and adding up data on these dimensions. The possibility of the aggregations is equal to the possible combination of dimensions.

In the OLAP Server all possible aggregations are mixed with the base data which contains the answers of the query. It can be answered from the data. There can be many aggregations that are calculated. Some parts may be calculated and the remaining part may be calculated on demand.
