Centos Server Guide

Sharp is best known in Los Angeles for an interactive dinner theater shows as their highly acclaimed murder mystery, a courtroom of their comedy, Dinner Court. They regularly play on their way from LA for this exciting brand of entertainment to service men and women based in California through the MWR (Morale, Welfare and Recreation). After several seasons at the club Mirage in El Centro Naval Air Facility, San Diego Naval Base and China Lake, Ralph Ramsey, who runs El Centro MWR, proposed changes to the traditional dinner show to meet repeat customers. He was first suggested by Neil Simon. "It was Neil Simon play," recalls Eric Sharp, producer / actor on Sharpo.com. "I had to remind Ralph that while we really wanted to continue to bring a dinner theater in El Centro, the ability to probe the full length play for a few weeks to make one was going to be a hard thing to ask of talent who was busy performing regular shows. Also, many of our players are constantly auditioning and performing in TV and movies by adding a full rehearsal schedule on their already busy lives is a very attractive proposition. ";

Eric, who is known for its extraodordinary memory, suggests Woody Allen's "Play It Again Sam." He did play 20 years ago in Kobe in Lakewood, New Jersey. Asbury Park Press review said that Woody Allen could do better himself. Although he was 20 years because he did play, he knew the line would come back to him. In this way, he could train other members of the team and the "head start" on the production. Eric wife and partner in Sharp Inc., Nora will play the part of Linda, his love interest in the game. So they could practice whenever they get a free second, which was not very often, because their baby, Benjamin, is only 6 months at the time. actors all poured their hearts into the production, knowing the victims were very small ones by our service men and women.

He was right, he remembered his part well. Is rounded with Duffy Hudson as a dead on Bogart and brilliant comedy actress Kerri Schmidle. Duffy has made a real name for himself playing Edgar Allan Poe in a one man show, "Shadow Of The Raven" and Kerri studied at the prestigious "second city".

The show, produced by special arrangement with Samuel French went up to 14 februar 2009 El Centro's club Mirage, and it was a hit. "The game is so well written. They may be non-stop for 90 minutes."

Since then, Sharp and the Company are made ​​to play the San Diego base, and next up is the China Lake. Of course, because he was so successful, Ralph in El Cento has asked for another 4 plays to be produced by Sharp next year, which means lots of rehearsals for very little between the 200 plus an interactive theater events they produce every year.

Today, many e-mail applications such as Sendmail, Postfix, or even MS Exchange was re-designed to minimize the possibility of becoming "spam-​​relay." From our experience, most relay SMTP auth attack compromised due to weak password-protected accounts. Once you have found and compromised accounts. Spammers authenticate using user credentials, they are approved through the relay server, which is then used to send spam.

Below are simple steps to stop these e-mail spam and quickly identify which account (s) is compromised.

Step1: Stop waiting on mail order .

Large quantities of spam e-mail to keep waiting for e-mail spool. What is worse is all the spam filling out all your / var. Therefore, it is always to keep mail order for provisional until you know your account has been exploited by spammer and send a large amount of e-mail.

Step2:. Check your mail log

Go to / var / log / maillog to have a quick look at the line of: <>. Maybe you'll see a lot of e-mail domains that do not belong even your organization. This is due to a false-mail spammers from :<>.

Step 3: Identifying the compromised account authentication SMTP auth link

Now, let us check those e-mail accounts that use. Running is sasl_username cat grep and sort. You should see a long list of attempts to login and session for those exploiting the account. You can also do a quick calculation by running wc-l command to see the total sessions for a specific user.

Step4:. Disable exploit e-mail

After SASL_username series, which has an account. We encourage you to disabled or to change the password for complex passwords.

Step 5: Move a mail order or delete unsolicited e-mail

Now, we need to deal with our mail order. Easier and quickest way is to move its mail order and make a home later. Or, you can delete those spam e-mail using a Bash script.

Step 6: Release Mail Order

Remember to start mail order after our household and keep the process on the monitor mail traffic.

All future trends in Internet programming is based on the creation of dynamic web sites with feature rich web applications that give a stunning user experience. PHP, server side scripting language, in combination with MySQL, open source database system, can do just that. PHP comes as a boon for creating Web pages that provide a unique experience for every user, so that each user gets exclusive and personalized view of web pages. MySQL has gained popularity for free access. Another popular software in the LAMP stack is Apache HTTP server that hosted the monstrous number of websites and web pages. Last, but certainly most importantly, Linux OS kernel provides a platform for developing, hosting and web processing applications.

LAMP acts as simple as the architecture. All application processing and query happens on the Linux kernel. Linux is the most dominant player LAMP software bundle. He gathers all the processing of requests and sorts them servers. Sites are located at Apache which puts them on the internet index. All HTML and static code is served directly from the Linux kernel, as well as dynamic PHP code, it is forwarded to the preprocessor to be processed before the HTML hosting.Preprocesor turn keeps PHP code and sends queries to the MySQL database. MySQL database serves query and returns a result value of the preprocessor. On the preprocessor data values ​​and data processing queries are sent to the kernel to be embedded in HTML code, and was later hosted on Apache server.

Not only do fast processing speed, but the availability of inexpensive too accounts for its growing popularity. Since the article on his invention was published in German magazine Computing, LAMP has found a gigantic number of customers in the world of Internet programming, and be rest assured it will continue to do so. LAMP provides flexibility and easy adaptability to newcomers, since only the assumption that knowledge of PHP and MySQL with a bit of HTML tags. LAMP phpMyAdmin allows the administration to have easy access to web pages and support.

Open source software is referred to as such because the source code is in the public domain and can usually be changed in almost any way the end user sees fit. This is a great advantage for those who are trying to save some money. Let us look at some alternatives to common commercial software.

Microsoft Windows or Mac OS
These platforms perform very well, but it can get pretty expensive when you buy multiple copies. This is where Linux steps up to the plate and really knocks out the park. Linux is (usually) free operating system with many flavors and distributions. It is important to note, however, that not all programs that run on Windows and Mac platforms will run on Linux. However, there are alternatives to almost every commercial program that becomes running on a Linux platform. Some of the more preferred free distribution of Ubuntu, Fedora, CentOS, openSUSE, and Debian, because they do particularly well in the office. If you want to go put paid Linux platform, Red Hat Enterprise Linux works very well and still not as expensive as a Windows or Mac OS. Now that you have a new platform, let's start on what will be used with it.

Microsoft Office
There is a great alternative to Microsoft Office called Open Office. Open Office is a replacement for all applications in Microsoft Office, including Word, Excel, Access, Power Point and others. If you want to add an alternative to Outlook, you need not look further than Mozilla Firefox projekt.Tvorci (mentioned later) to make Thunderbird. I used this for years and never let me down. This is a full-service e-mail client with many features of Outlook, including an additional calendar (Lightning ).

Internet Explorer
I'm recommending it not only because it is an open-source and free, but also because it is generally believed to be more secure than Internet Explorer (from a security standpoint). My recommendation for this alternative is Mozilla Firefox. This is the only browser can I use personally, and it has all the features I have ever used the Internet Explorer.Dodano good that is highly adaptable to the skin and add-ons that look and act the way you want.

WinZip
Sometimes you run into a compressed file and need something to unzip them. This is where our next handy little tool comes in 7zip. This is all the features of WinZip, but it does not cost anything. I used this for years and could not be happier with it. This provides the ability to extract to give the place or the current folder, and can be easily opened. Zip file.

Microsoft SQL Server
Excellent alternative to MySQL, which is manufactured by Sun Microsystems, a trusted name in industriji.Mogućnost Community Server is free. This option means that the buyer will maintain the server yourself without the help of the sun. That's a lot of great opportunities and lead as well as commercial alternatives to Microsoft.

instant messengers
Some companies choose to communicate via instant messenger. For them, I recommend Pidgin. Pidgin is a universal IM client, which means that it can handle multiple protocols (AIM, Yahoo, MSN, etc.) at the same time. It is convenient even if not implemented open source office.

Here we have it, a list of programs to get up and running for office without a potentially software costs at all. By reducing overhead like this, we can pass the savings to a customer or not. It is the decision of the owner. Either way, the job does not consume as much and potentially make more money simply by making these changes. Good luck with your new implementation.

When you install your first internet CCTV camera, you can track the camera installation manual and will soon see the camera images to a computer connected to the same router as part of fotoaparat.Zabavni trying to access camera outside the local network, via the Internet and This is where port forwarding comes in. This article describes how to set up port forwarding.

Once you have your internet CCTV camera in hand, the first step is to configure it, unless you purchase a fully configured camera from a specialist supplier. Very soon you will be able to view the camera image to your PC or laptop. Since the configuration process you will learn the internal port number of the camera, and the LAN IP address (an IP address on the local network). For example, the LAN IP address could be something like 192.168.1.101 and the camera's internal port number, say, 80 If the wireless internet CCTV cameras, then you will go to key wireless settings to the camera and get to that moment when you turn the camera off the router, and as if the magic was still seen moving pictures!

At this stage, the camera is only available within the local network, in the same zgradi.Pravu beauty of the internet CCTV is that you can see your property from anywhere in the world, but as it stands, if a key address in the cams on the web browser computer elsewhere, your router firewall will block the incoming request and you will get a "page not found" message. Port Forwarding, sometimes known as a virtual server, is a way to ask the router to send incoming request further to the camera, instead of blocking it.

on your computer, you need to open your router administration pages to set up port forwarding. Look for a menu item called something like "port forwarding", "port mapping", "routing table", "service desk" or "virtual servers", usually under firewall. Here you will usually find a table with something like the following items that you need to type:

LAN IP address (from the camera. LAN or Local Area Network means that your home network.) Incoming Port Number WAN (WAN or Wide Area Network means the internet) Destination LAN port number (camera)

LAN IP address is the local IP address of the camera that you have chosen during set-up, eg 192.168.1.101.Broj destination port is the internal number of the camera, or the number you have selected or default which is often 80.Dolazne WAN port number is the port number that you use to access the camera over the Internet. You can only select a specific port numbers - just above 8000 is a safe, say the 8150th In some routers, it is not possible to set the destination port, in which case the camera's internal port must be the same as the WAN port. In our example this would mean changing the camera configuration, so that its port is 8150 to match the WAN port instead of the default 80th Once you've keyed in the data router, you need to know the WAN or Internet IP address. You'll find it at the status screen or DSL in your router's administration page. I will assume for this article that this IP address is static (not changing over time). Be careful that you are looking for Internet IP Address, not a local one that starts 192.168.

Having worked through this process you will be able to access the camera from the Internet. For example, if your network's Internet IP address is 91.103.218.59, and will address key 91.103.218.59:8150 http:// in the address bar of your browser. After logging in, as if by magic you'll be able to see their property or family wherever you happen to be.

cPanel related to Unix-based web hosting control panel, which provides a GUI automation tools specifically designed to ease down the process hosting the web site. cPanel basically uses a 3-tier structure that provides the functionality for administrators, resellers and web site owners, to control various aspects of the site and administer the server using standard web browsers. It also has a command line and API-based approach, allowing third-party software vendors, web developers and web hosting companies to automate standard processes of system administration.

cPanel or function as a dedicated server or Virtual Private Server (VPS), supporting applications such as Red Hat Linux, Unix and FreeBSD. cPanel general approach to port 2082, while a secure SSL server running on port 2083rd

Many accessories are also available at additional cost, such as Auto installers like Fantastico, and Softaculous Installatron. Auto Installers relate to a bunch of scripts that help automate the installation and updating of web applications, the most notable being WordPress, phpBB, Joomla!, WHMCS and ZamFoo, among others.

If you are running cPanel Server and want to know which version you use, it is very easy. All you need to do is log on to WHM / cPanel. A version will be displayed in the upper right corner. Alternatively, you can check the version of cPanel on the server by running "/ usr / local / cpanel / cpanel-V" from the command line.

Second, the cPanel server, your priority becomes the supreme sigurnosti.Osnovne security need of the hour is to keep the latest stable version of cPanel on your server. To check the latest version of cPanel on the server, you can log on as root and run a command like "# / usr / local / cpanel / cpanel-V". And if you wish to update cPanel user, run the command: "# / scripts / upcp ".

Are you looking for a 'free (cost free) and simply "anti-spam or spam blocker solution for your organization to support multiple email domains

Are you looking for anti-spam solutions can be deployed in a production environment in less than 20 minutes?

ESVA Email Security Virtual Appliance (ESVA) is a FOSS-based anti-spam solutions created by Andrew MacLachlan in 2005. ESVA a pre-built virtual machine running on virtual strojevima.Najnovija ESVA version can run on VMware, running on Citrix XenServer, Microsoft Hyper-V and VMware platforms.

the development of applications by the station for almost two long years to the day after the release version of the 2058th I was so happy that the current version 2060 is not available. To download the latest version of the GD ESVA visit the official website.

ESVA main components are:

CentOS - Robust Red Hat clone operating system MailScanner - Anti-spam package for e-mail gateway system. MailWatch-web-based admin page for MailScanner Postfix - the e-mail SQLgrey - Greylisitng filtering Webmin - web-based admin page and CentOS Postfix admin ClamAV - Open Source antivirus clearinghouses Distributed Control (DCC) and Vipul's Razor - Bulk mail spam detection Pyzor - Spam detection network SpamAssassin - Famous spam filtering packages for the header, text analysis, Bayesian filtering DNS blocklists and filtering database FuzzyOCR - Content and properties of image filtering based on fuzzy logic MailGraph - Graphics Mail statistics tool for

Why use ESVA?

The advantage of using the ESVA:

free in price, robust system, filtering accuracy domain of the sender black list domain of the sender and the white-list quarantine and release a report (based on per user or per domain) easy to use and convenient.

I'm engaged in self-customized version of our ESVA DataCentre since 2007 and is still one of our best anti-spam solutions. Although, Bayesian filtering method takes time to build on spam or ham database. Overtime, ESVA on mail filtering becomes more effective to distinguish between ham and spam comparable to some commercial products.

We have 2 units ESVA deployed at Layer2 running our DataCentre to take care of more than 500 domains, and 10,000 e volume per hour. Our ESVA used for e-mail quarantine, anti-virus scanning, OCR and fuzzy Bayesian filtering.

However, several important features that I think the author must include :-

No SMTP authentication and LDAP integration No Subject Filtering No keyword filtering Invalid GIF and JPEG filter

Some of the above weaknesses can solve the script adaptation. However, I understand the feature of each pack and plug-in and file path. Currently, I'm making adjustments to the configuration and the FAQ and we hope that anyone using ESVA can benefit from it.

However, ESVA is one of the most effective and powerful FOSS-based spam solution that I have ever deployed. This will definitely help your organization to spam issues.

1 Introduction

intrusion detection and incident response are key components in securing funds for any organization. What actually falls? How to detect intrusions? And as a response to the invasion of our key areas for this article.

In order to detect intrusions must be aware of the normal behavior of their network infrastructure, so that any abnormal behavior can be seen easily as a drop of blue ink in a glass of water and you need a drug that attacks the other will disappear. There are many systems and scenarios by which you can detect intrusions in network infrastructure.
Intrusion Detection System (IDS) can detect intrusion in a host or entire subnet included in the environment, the deployment of IDS depends on the design of your network infrastructure. That this article applies let me explain how this is included in the IDS environment.

A host based IDS (HIDS)

B. Network-based IDS (NIDS)

let's discuss the NIDS, let's say you have a DMZ where you have FTP, HTTP and the database server is located, and you are worried about intrusion from the Internet facing interface of your perimeter devices.

To monitor the intrusion on the environment prompted break package on the level of detection, the choice I would recommend the de facto standard for intrusion detection, Snort!

2 Analysis Package

scenario, a security analyst must follow the intrusion caused by the server, the answer is the placement of Intrusion Detection System in the DMZ.

Preparing the Order Box:

Snort is the de facto standard for intrusion detection, and I'd say for intrusion prevention as well. Sources can be downloaded from the Snort snort.org that is freely available. At this stage I am assuming that you have downloaded Snort, let me clear the open source Snort Intrusion Detection System that runs on Linux / Unix platforms.
I would also recommend that you prepare a Linux machine (it is recommended to use Cent OS Server) to stop all unnecessary services you have the MySQL server, PHP and Apache installed on your sever, team up to Linux in the first place. When you are done with their solid Cent OS server, but it's time for snort
Un tar your Snort source you just downloaded to / usr / snort and use the following command to install Snort

snort configuration in accordance with

# configure - with-mysql - enable-dynamicplugin

Once you get any errors during configuration and then build a configuration with the make command

If you do not show the error then it's time for a fresh install is configured with a snort make install commands when you are done with installing Snort Snort need to add a user to use the following commands

groupadd snort
useradd-g snort snort-s / sbin / nologin
Now you must create the following directories.
mkdir / etc / snort
mkdir / etc / snort / rules
mkdir / var / log / snort
cd etc / (you do not it's not / etc etc to the DIR the Snort source code)
* cp / etc / snort
in the telephone directory the source code would be / etc / rules directory now copy all the rules to / etc / snort / rules directory
At this stage of your IDS is installed now need to learn how to use this effectively IDS to detect intrusions come in your DMZ.
This is a high level, if you want to learn more about installing and configuring Snort, please read the user manual is available on snort.org

Snort runs in four different modes which are as follows.

the Sniffer mode, which simply reads packets from the network and displays them for you in a continuous stream on the console (screen ).

A packet logger mode, which logs packets to disk.

A packet logger mode, which logs packets to disk.

A Network Intrusion Detection System (NIDS) mode, the most complex and configurable configuration, allowing Snort to analyze network traffic for matches against a user-defined rules and conducts several activities based on what he sees.

Let me explain how Snort, one by one ..
First, let's start with the basics. If you only want to print TCP / IP packet header on the screen (eg sniffer mode), try this:

# Snort-v

This command will run Snort and just show the IP and TCP / UDP / ICMP headers, nothing else. If you want to see application data in transit, try the following:

# Snort-acting

This suggests Snort package for data display, and headers. If you want even more descriptive display, showing the data link layer headers, do this:

# Snort-VDE

(As an aside, these switches can be broken and smashed together in any combination of the last command can also be typed as:. I will do the same thing .)

# Snort-d-v-e

What we want to detect intrusions in the DMZ will run Snort as an intrusion detection system, to allow for network intrusion detection (NIDS) mode, so you do not have to record every packet sent to the wire to try this command Snort-dev-l. / Log-h 192.168.1.0/24-c snort.conf

where snort.conf is the name of your rules file that will apply the rules configured in the snort.conf file to each packet to decide if action under the rules in a file type should be taken. If you do not specify an output directory for the program will default to / var / log / snort.
One thing to note about the last command line is that if Snort will use the long way as IDS,-v switch should be left on the command line because of the speed. The screen is a slow place to write data packets can be dropped, and the writing on the screen.
It is also not necessary to record the data link headers for most applications, so that you can usually omit the-e switch, too.

Snort-d-h 192.168.1.0/24-l. / Log-c snort.conf

This will configure Snort to run in its most basic NIDS form, log packets that trigger rules specified in the snort.conf in plain ASCII to disk using a hierarchical directory structure (such as packet logger mode ).

Now as I have covered enough to snort let me explain that Snort will alert when they detect intrusion as I mentioned at the beginning of a document that can only detect intrusions that you know the normal behavior of your network.
When Snort generates an alert message will usually look like this:

[**] [116:56:1] (snort_decoder): T / TCP Detected [**]

The first number is the Generator ID, this tells the user what component of Snort generated this alert. For a list of gids, please read the etc / generators in the Snort source. In this case, we know that this event came from `` decode''(116) component of Snort.

The second number is the Snort ID (sometimes referred to as Signature ID). For a list of preprocessor SIDS, please see etc / gen-msg.map. Rules-based SIDS are written directly into the rules of the SID option. In this case, 56 is the T / TCP event.

The third number is the revision ID. This number is primarily used when writing signatures, as each design rule increment this number with the speed option.

Summary:

This is Part 1 of intrusion packet level analysis, I will be setting up further in the second part of

VPS hosting is the right choice for you if you want more control than you get from the hosting bills, but you do not need the power of a dedicated server. We are still sharing a server with other people, but you have your virtual environment with no access. What happens is the main server is divided into smaller, virtual "servers." Eventually you'll get all the independence and flexibility that comes with a dedicated server, with no major price tag.

You should be careful about a few things when you're looking for a VPS host. You'll find some of these features more useful than others. Here are some of the major perks to being on the lookout for in your search.

Linux is far more popular for the management and maintenance of servers. It's free and you can have for $ 0.
This means that you are getting one of the most popular hosting platforms and low cost server maintenance. Linux is most useful for a variety of web languages ​​such as PHP, Perl, Windows and more optimized for ASP.

on Windows, on the other hand is paid platforms and you'll have to spend several hundred dollars on this platform. Linux distributions that are hosting most of the Fedora and openSUSE, as well as Unix.

The 85% you will find Linux installed on most hosting companies. Windows is also popular in server management, but have not yet developed many alternatives for Linux and modules that can be used with Linux.

Most of the newer software and web languages ​​require Linux as many users use this open source platform for hosting.

Microsoft Windows Server as an alternative to hosting and works very well for ASP based web sites.
Windows is still under development, while Linux is distributed to many versions of all server editions.
Start a new standard in the hosting industry is hardly going to change because that Linux is a great advantage, while still in the background as a desktop platform.

In most cases it does not matter which platform you use for hosting. But for most people who want to start a web hosting is cheaper to run the Linux platform.

Basically you should not encounter many problems when choosing any of these platforms for their web server, because each program for both platforms should react normally.

If you can not move from one file to another hosting platform you still should not experience any problems.
So, the conclusion is, if you want to save some money you should probably go to Linux, but it's your choice.

dedicated hosting is also known as managed hosting where the client leases an entire server that is not shared with anyone. It is beneficial for the client who hired because you're able to have control and monitor the work of the server for your klijente.Punu control on operating system and hardware you need. There are cases where the available server hardware can be owned by a service provider or they can help your already available jedan.Uvjetima each of them varies depending on the service provider.

In cases where the operating system support, you will have to pay a monthly fee for the services they provide for your business or organization. These are only offering committed service. There are commercial operating systems which are known as Microsoft Windows, Red Hat Enterprise, while others are on the open source community, without compensation to be paid to them. Some of these are not charged include CentOS, Fedora Core, Debian and Linux distributions like FreeBSD, OpenBSD and netsBSD

options available with a web hosting package a very broad range, and can be a bit confusing to understand - especially since the options are in many ways, and condensed in different ways, and to purchase a package online. I hope I can give you a breakdown of categories and features are in and help you to focus on features that are important to you.

I break the features down into 10 categories and will discuss the categories one by one company that you understand the options and make informed buying decisions.

10 categories of web hosting package features

operating system web server Bandwidth Disk Space Domains e FTP database Control Panel Software / Programming

1 Operating System

is a core operating system software running on your computer. It manages the physical hardware on the server and tries to optimize memory usage, disk space, network and processor requirements that come into the machine. OS may not be the same as your desktop, or even the OS you use to develop your website. In fact, the majority of management functions to move through the web GUI, you would never know or care what operating system the server is.

dominant operating system, you will find while shopping for web hosting services including Windows and UNIX. With Windows you will see the versions available, such as Server 2003 or Server 2008 and UNIX you will see many brands of Linux, usually CentOS, Debian, or RedHat. Choosing between UNIX and Windows is an important decision, and involves a lot of variables, but in the end it simply means deciding if you want to build your website with open source technology and with Microsoft technologies. complete write-up option is available on the Department in order for this topic.

research program that you wish to use or display a web page to check whether there are any Microsoft technology requirements (MSSQL Database, MSAccess database, ASP, ASP.Net). If you are not pressing reason to use Windows, UNIX, then you will probably be a better choice for you. UNIX open source scripting language a bit faster, but it is also slightly cheaper than Windows.

There are a few specific sub-functions of an operating system that may be of importance to you.

Do you need a virtual private server? It gives you a dedicated virtual operating system all to yourself instead of with you can share with other OS. We still share the machine with others, but there are stricter walls in guaranteed bandwidth, CPU and memory even if the web site on the same machine is getting hit hard. It gives you a great configuration choices with everything, having your own OS. These packages are more expensive than the common option, but worth it if it is a web raste.VPS packages usually vary the amount of RAM dedicated for you, so I would recommend going with the lowest package and monitor the use of RAM over time and upgrade to higher package by needed.

Do you need a dedicated SSL certificate? Most sites offer a shared SSL certificate, which is fine for some smaller sites, but if you do medium or large ecommerce site will need a dedicated certificate. ; Some reasonable customers will send in their personal and credit card information without a warrant valid SSL certificate also some private shopping applications require a dedicated certificate, and be careful when shopping for this - some hosting services they say .. give the SSL certificate with all its hosting plans, but do not explicitly say that the common belief. If the plan does not include a dedicated IP, then the common certificate.

directly to remotely administer your site, you may have to shell us, or UNIX, or Remote Desktop in Windows. The possibility of UNIX shell sometimes called SSH shell, telnet or Secure Shell. These options are only useful for you if you intend to do a low level of maintenance and tweaking, mainly in the VPS package. with a good hosting package with high-powered control panel, you will not need any of these.

you see mention of the ability to schedule Cron jobs -. This is a UNIX version of the schedules that capacity is only required if you want to run scheduled tasks at set times, such as night backup. Most good control panel provides an interface to enter the cron job, but they also provide an interface for performing maintenance such as backups. probably never need this feature.

web hosting companies usually offer a Microsoft IIS or Apache web server UNIX. Both have their plusses and minuses, and it will make a difference to you if you are developing a website or program you are running requires one or the other. Apache as open source itself, has little more hooks in it to run many Open Source Content Management System and the blog engine based on PHP, Perl, Python, and so go with Apache, if that's all you need Windows IIS is also a pretty good open source content management systems and blog engines is based on ASP and ASP.Net, but I'd suggest going with the PHP / Perl / Python web applications on Windows IIS -. see above discussion of why the operating system.

SSL certificate is a host web server, a web server must do additional processing SSL HTTPS requests -. This is to encrypt / decrypt and validate the data passing between client and server for this reason, some argue that you should shy away from the web hosting packages that offer free SSL certificates for all shares. You might end up sharing a server with 100s of other sites that are eroding the server. start a website just to go to HTTPS SSL mode for the actual entry of credit card and not the entire site -. but do not know if other sites on the server are well-run

Great for management?

web control panel is an important resource for any tool to web administrator. While an expert or experienced administrators may choose not to use the web-based graphical user interface such as cPanel ability greatly reduce frustration and improve efficiency in web site design and interaction is invaluable for most web owners. cPanel is listed as one of the top panel of the program currently in existence. This is an award-winning web resource that is currently offered on many web hosting plans, such as 600Host.net based in the UK. This hosting company offers cPanel on all their packages and they have proven themselves to be top-tier UK web hosting.

cPanel is software that is owned and produced by cPanel Inc. is acquired through licensing as meant to be used by commercial web hosting companies. In most cases the only way to make active use of this interface is to be granted access to it through a web hosting company. However, some businesses, educational institutions and nonprofit organizations can often get a license for this product showing a reduced price. In some cases they even granted free use.

cPanel software is exclusively for the Linux operating sustav.Platforma specific software has a variation that can run on multiple systems. These systems include Red Hat, SuSE, Fedora, CentOS, Mandiva, and similar operating systems.

Kismet is a wireless network detector / sniffer which can give you an enormous amount of data on wireless networks. Wireless network security flaws are well documented but often very difficult for the ordinary man to understand. I'll be showing you how to use kismet with even having to install Linux, or compile kismet.

First you need to keep the remote exploit.org and download and burn their own CD's auditors. (If you do not know how to burn an ISO image, go to Google). This version of Linux do not install or modify your hard disk, it will boot from the CD and use the RAM drive (memory ).

the auditor is not only a great tool for testing the security of wireless networks with kismet, but it also has many other tools of computer security at it as well.

client window

Next, to start Kismet proceed Linux version of the Start menu, then click the auditors.
Now go to wireless / scan / tools kismet / kismet.

Once you click on the Kismet will ask for a default location to place Kismet log files for analysis later, just click the desktop or temp files.

Now I'll show you how to use Kismet. When kismet initially opens you will see a green box with numbers and network names (if they are with you) by clicking away not to be overwhelmed. (Also, I can show you how to use kismet, if you do not have the correct wireless adapter, get ORINICO Gold Classic card from eBay.) Orninco gold classic card will be automatically detected by the auditors Linux.

Kismet will show the wireless network SSID (name), device type (access point, gateway) encryption or no encryption, IP range and number of packages. Kismet will pick up the hidden SSID broadcast networks with disabilities also will NetStumbler.

Now, press H to the Help menu. This will give you the nuts and bolts of how to use kismet. If the card to the network you are auditing and press "C", Kismet will show you all computers using the wireless access point / gateway. This Kismet screen will show you the MAC address of clients, production wireless adapter, the range of IP addresses and traffic.

Kismet: Help menu

Now to get out of the screen, press the "Q". Tab down to the main Kismet screen to another SSID and press the "I". This Kismet window will display detailed information about wireless mrežu.Kismet detail screen will display the type of network (Infrastructrure / Adhoc), signal strength, channel, encryption type, and more.

Kismet will also give you a warning sound when new wireless networks are detected or suspected security alerts or customers are within range. Suspicious clients would be people like you who are using Kismet or Networkstumbler. Unlike you, and you could be looking for Wardrivers venerable network to hack into.

Kismet Alert Page

can prevent war drivers from discovering your wireless network performs the appropriate place of research that will help limit the signal bleed off unneeded areas. You should write the MAC address of the suspect and keep an eye on your access logs. If war drivers are really stupid just look out your window and look for cars with strange antennas.HA ha ha.

Kismet is more than just a tool for detecting wireless networks, can be used in combination with other tools to crack WEP / WPA. Many sites will claim that WEP can be cracked in less than five minutes. This is only half the truth, because it could take several hours, days, months to collect enough packets to crack. Good luck and have fun learning more advanced applications kismet.

If you're hosting, you probably heard of Linux. It was first introduced in the year 1991, and it comes to one of the most popular operating systems available on the market. She appeared to be one of the best among the choices that webmasters choose other than Windows and Mac OSX systems. One of the reasons that make Linux popular is because it is open source. Many developers are constantly working to improve the system. There are many Linux distributions, and let's look at some popular ones.

first want to mention here is Ubuntu. They are considered among the most popular distributions out there because it has features that are comparable with Windows hosting. It is also popular because it is designed to be more suitable as a desktop operating system, instead of server systems.

the following type of Kubuntu. With your name, you may have to guess that is similar to Ubuntu. That to.Dva are very similar in their operations and functionality. However, they do not use two different types of file system. In addition, the two systems are very similar in its functions and performance.

Then there is the Debian distribution. It is built on Ubuntu and Kubuntu. It is commonly used in the web hosting industry. Although it is hard work, Debian is still very flexible. It can also be used for desktop and server operating system.

The second type is called Fedora. This is usually included in a dedicated hosting package. This distribution is based on RedHat Linux. She has maintained a commercial distribution that often compete with Microsoft Windows. It is commonly used on older computers due to limitations and its ability to use fewer resources.

Last but not least, we have CentOS. It is known as an enterprise operating system community. This is also based on RedHat Linux. This distribution is available free through the GPL and therefore, Red Hat has a lot to get used commercially, which led to a more stable and secure performance. This distribution is getting popular and now widely used as forms in cPanel and WHM is used in reseller hosting.

Using Linux fdisk and parted commands / Utilities

The Linux fdisk partitioning utility that runs with the fdisk command. Almost every Linux distribution contains the command fdisk / utility.

Some Linux distributions also includes a utility called "parted" (GNU parted - partition editor). I parted utility to perform simple typing run parted command.

for basic Linux partitioning tasks, use the fdisk command / program.

No, do more advanced Linux partitioning tasks, like resizing a partition or partitions, copying, use the utility splits .

If you run Linux split command and the tool does not start, you can download the program and distributed to install it on your Linux distribution.

Some Linux distributions also use other tools for partitioning, especially during the (own), the installation routine.

"Disk Druid" Hard disk partitioning GUI tool used to Red Hat and Fedora

installation routine Red Hat (Linux and Fedora), allows you to use a partitioning tool called Disk Druid to partition your hard disk (a ).

disk druid is actually a GUI interface (front) to melt the utility. When this task with disk druid, such as creating a partition divided the utility actually uses the "background" to achieve the division of tasks.

Linux Commands Training Tips: Red Hat Linux is very expensive and Fedora is free! Red Hat sponsors Fedora as creating a "test bed" for features to be added to Red Hat Linux.

So, download the Fedora or have it mailed to you very cheap - if you explicitly need to learn how to use Red Hat.
From "Learning for Linux System Administration perspective," Red Hat Linux and Fedora Linux distributions are almost identical.

options available in the "Disk Setup" screen (Disk Druid in a Red Hat installation routine) do not currently use all the features parted utility.

For example, divide the utility can be run on the Linux command line (simply by typing the divorced and pressing the Enter key) to change the size (increase or decrease) the size of Linux partition, and you can not do this with Disk Druid (from Red Hat installation routine ).

Linux hard disk partitioning concepts and commands covered here relates to: Red Hat Linux and Fedora Linux to run fdisk, parted, and Disk Druid - and also apply to Ubuntu, Slackware, Debian and other Linux distributions for fdisk and parted.
