Centos Server Guide

RData is the Network Time Protocol for the immediate date and time setting another stroja.Satovi are synchronized with the input RData-S switch (no switch command only checks the time, but not set anything).

RData is an older standard that in many cases has now been replaced ntp / ntpd. Unlike NTP, RData set a new time and now is more convenient in situations such as the initial setup. Sudden changes in the clock settings can cause problems for some software (NTP weather changes gradually). No NTP may not be available in some systems, and during some initial settings actually wants to set the correct time as soon as possible.

Under Linux, RData has its own service network and is supported by the Standard Time Services instead. It uses port 37, and can work over TCP or UDP (with the-U switch).

This is the tutorial How public RData Server .

Public RData server need two packages: xinet and NTP

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 performance was going to be a tough thing to look for the talent that he 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 your already busy life is not 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 in comparison with those made ​​by our service men and women.

He was right, he remembered his part well. Cast 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 his 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 a few gigs between 200 plus an interactive theater events they produce every year.

LAMP is the most popular combination of Web technologies at present. It stands for Linux, Apache, MySQL and PHP.P could be Perl or Python, but none of them ever came close to being as widely accepted as PHP is today. Tens of millions of websites powered by PHP because of the simpleness.

Therefore, LAMP is simply a 4 technology or software packages that are mature and popular in creating and hosting web sites. What are they exactly? Let's take a walk.

1 Linux - Linux is an operating system that is directly responsible for driving hardware machines called computers or servers. She has a very long history, itself derived from Unix, which by the way, can not be a popular series of Microsoft Windows as we know, but some of the world's most powerful and important computer systems and networks that are powered by Unix. Linux can be seen as a branch of Unix development that focuses on ease of use and prilagodbe.Cijeli a number of different Linux distributions exist today, either commercially or non-commercial purposes, to name a few that are commonly used, Red Hat, Debian, Ubuntu and CentOS. They contain exactly the same (almost) core that is why they all called Linux, but they each have quite different although similar set surrounding the distribution of software packages. Linux is the most fundamental part of the LAMP platform.

2 Apache - Apache web server is performing as well as the surrounding software package in Linux distributions and to order a physical web server identifies the client (such as browser, Firefox, or something) and respond to requests by serving Web content (such as web page or part of the video ). It's as simple as that. Apache was developed by the Apache Software Foundation and released under Apache License.

3 MySQL - MySQL is the world's most used open source database. SQL is a data design and manipulation of the language used in a variety of database management systems, including the Microsoft, MS SQL. This is no exception for MySQL. The LAMP hosting environment, MySQL is responsible for hosting, search, create, crop and manipulate databases that contain your valuable data.

4 PHP - PHP stands for Hypertext Pre-processor and it is the most popular scripting language that is especially suited for web programming. Each website you see today has a 50% chance that it is powered by PHP. One of the main reasons why the spread is so vast that it is easy to learn and quick razvijati.Ulogu that game is similar to other programming languages ​​- the design and conduct of business logic. However, while many other platforms compiled languages​​, PHP is not.

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.

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.

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.

There are many different types of web hosting services that allow organizations to host their content on Internetu.Dedicated Server is extremely cheap and effective Internet hosting service that allows an entity to lease an entire server for your exclusive use. Such virtual private server hosting has obvious advantages over the hosting. This enables organizations to choose their own operating system, hardware and server (s). It is not uncommon to provide a system management server dedicated server hosting company. Other potential benefits include reducing overhead costs, and thus a significant improvement in profit margins. Data centers, which provide redundant power sources, and automatic environmental comfort objects are often deployed for housing cheap dedicated servers. In such cases, the server hardware belongs to the service. In some cases, such as service providers and to expand support for the relevant operating system and / or applications.

Choosing the right operating system for a dedicated server is determined by factors such as ease of availability, price and staff familiarity with these software. Generally, customers can choose from freely available variations of Linux and Unix based operating systems (such as CentOS, Fedora Core, Debian, etc.) and more commercial varieties such as Red Hat Enterprise. Because of the widespread popularity of the Windows operating system, many users are increasingly opting for windows <>. These servers run on Windows OS through a program called Microsoft SPLA. The level of support offered by the data center depends on the specific server the client's choice plan. Typically, such plans should facilitate the management server and includes the upgrade of the central system.

Select the appropriate operating system based on the server `s work. Linux is a powerful and versatile operating system, Windows, and is known for its easy-to-use operating system and versatility. Deciding the right server is definitely a trial as a decade ago, Microsoft's Windows NT and Novell `s NetWare4 are visible in use, but NetWare is now totally disappeared and the Linux version is found to be a good choice. Both Windows and Linux come in desktop and server editions.

Maintenance and security are one of the important areas to understand the real differences between the operating system. Linux is commonly called a distribution, also known as 'distros', and was released around the same time frame using the same version of the kernel (operating system). Linux needs a careful consideration of the hardware driver as the hardware has recently announced to be appropriate, and that includes the motherboard, as well. Linux installation should be carried out by persons with adequate knowledge to run the operating system and its applications. Linux is stable and secure than Windows.

On the other hand, Windows offers simple installation and works even in default mode, except that includes a number of drivers, regardless of hardware type and has a huge variety of software. However, suffered with frequent security problems challenging the critical patches include a reboot. It is also set to the right of the purchase price for the application, except for ongoing maintenance needed to keep it updated and stable.

Comparison Linux vs Windows includes other considerations such as price, features and specialized support. Linux server-oriented version with suppliers, and some are offered with 24 / 7 support paid. There are cheaper versions of the distribution of profit on Mepis, Fedora and Xandros, and others, which are offered at very low cost to get started, and Debian, Slackware, Mint, Mandriva, Fedora and Red Hat and Ubuntu are free versions.

On the other hand, Microsoft Windows Server regularly with 32 and 64 bit versions with specialized capabilities makes it ideal for small and medium-sized businesses. However, the biggest hit was that Windows is encouraged by the multi-billion dollar company and is compatible with most software, except that it is very easy to use and understand that even the average user can make the best of it. Windows price varies dramatically based on the number purchased and the annual maintenance agreement or licensing plan.

Significant differences in the Linux version is not talking about the quality of the software or drivers' availability, but are offered. Depending on the Linux distribution, users can get fast and 24 / 7 support paid, and that should suit any corporate environment. Purchase of operating system and hardware together provide support for embedded hardware, the second May require research to ensure the motherboard, network adapter, chipset, and others are supported by Linux verziju.Drugih non-Linux options include OpenSolaris, and many variants of Berkeley Distribution software.

Scalability, high performance and low delay are the key point in the popularity of Linux dedicated hosting. Usually, all Linux and BSD distributions comes with nearly impenetrable security features thousands of free and open source applications. Linux does not require any license fees, even if you use it for your business or industry or any other form of profitable purposes.

Now days, there are two Linux distributions offer their server operating system for free. They are -

1 Ubuntu (Debian Derivative)

2 Red Hat (RPM based)

can get a copy of Ubuntu Linux server operating system from its official website. You can order a free CD / DVD, or alternatively you can download. ISO file from their site, and later to burn the CD / DVD and create your own CD / DVD. If you do not know how to burn and create a Linux CD, no problems, the official Ubuntu web site offers a comprehensive tutorial for it. You can get a free burning software out there and follow the step-by-step guide and you are done! Remember that the Unix operating sustava.Instalacijskom process and other things are completely different from the RPM operating systems.

On the other hand, Red Hat's RPM operating systems. They do not offer any media from their official website. But, fortunately, some magazines offer CentOS DVD along with their books. But if you want to get the latest distribution and do not want to wait, then the best way is to take over. ISO file and baking them with your favorite CD / DVD burner software.

Here is a step-by-step guide to setting up a server -

...

the last phase of installation - updating an existing operating system to the latest security updates. Simply log into your server and type "sudo apt-get update". Congratulations! The system will update itself and your server is also up!

sizcache = "0" sizset = "66">

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

1 Operating System

2 Web server

3 Bandwidth

4 Disk Space

5 Domain

6 Email

7 FTP

8 Database

9 Control Panel

10 Applications / 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.

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 common features, but is 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.

2 Web server

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

3 Bandwidth

This is a measure of the amount of data transferred to / from your web site, usually on a monthly basis. Keep in mind that a typical web site carries a very small amount of content each user, and although the package offers only a few appearances for the transfer of a month, you will most likely not shift their grounds. If you do not, then your website is really popular with the thousands of visitors, and you should be generating a nice income. Most web hosting companies will spell out what is the penalty for the failure of its stake -. It's usually a dollar or two per gig, which makes it cheaper to upgrade to the next highest package of course, if your website is heavy on photos or multimedia, May you need a larger share of monthly bandwidth immediately. Fortunately they all offer a monthly look at the meter bandwidth usage, so you can plan accordingly as your site grows in popularity.

Some hosting companies offer unlimited bandwidth package -.. Be careful of this, there is no such thing as unlimited bandwidth, so what you are selling is unmetered bandwidth Many of them with unmetered offers will notify you after the purchase of accounts of what their acceptable use policy on bandwidth and disk space, disallowing you from performing night 500gig backups of your PCs and such activities. In fact, many of these rules also stipulate that you must upgrade to a larger package, if your website starts to hurt on the other permeability of the host machine together again, this is not a bad policy. if you get a notice of violation, the activities of your Web site, it is so popular that your income covers the additional costs of a larger package.

4 Disk Space

This is the allocation of bytes on hard disk gives you for your web site. Great website with 100s of pages can easily fit in a gigabyte of space, so you do not need that much for a typical web page. If a website has a catalog of thousands of items for sale, stored in a database with a few pictures of the piece, then you will need to improve significantly in the disk. Usually as a place to grow in popularity and content, will be upgrading the bandwidth first, and get more disk space, with an upgraded package.

Some hosting companies will include database space and email your space in the allocation of disk space, so plan on how to separate space.

As with any bandwidth, many web hosting providers offer unlimited disk space, and there is no such thing as unlimited disk space. What is sold is unmetered disk space, with the acceptable use policy. it is difficult to violations of their acceptable use policy of normal web pages, just doing something outside the norm, such as hosting and anonymous ftp site of fake files.

5 Domain

This is the number of web addresses that can point to your web hosting account. Almost all offered under the domain where your main site is YourSite.com and you have the domains and files.YourSite.com. Many will allow you to points outside the host DNS records pointed to your email account or a folder, but some do not. This may be referred to as Add-on domains, and most will offer at one of their packages more add-on domains. It allows you to purchase additional domains and point to a separate folder inside the host account. This way you can run multiple web sites that appear completely unrelated, to be physically located and jointly managed.

Many web hosting providers offer one or even more free with your domain account. Some even offer free domains of life, saving $ 10 a year for the domain. Be sure and shop for this option if you want to save a few dollars a year.

6 Email

Almost all web hosting providers offer e-mail, giving you an e-mail. Most of them also offer web-based e-mail, POP and IMAP access, spam filtering. where they differ is the number of e-mail accounts they provide, the total disk space or on a mailbox, and advanced features such as mail list management. It is up to you how important e-mail is you and your web site -. There is plenty of free e-mail service on the internet so it was never an important set of features for me

Many web hosting providers offering unlimited emails, but again there is no such thing. As your e-mail accounts grow, the bandwidth and disk space used will also increase, and none of them is unlimited. So finally break their acceptable use policies and are forced to upgrade to a larger package - again, not a bad thing if your website is growing and creating income for you

.

7 FTP

is an FTP file transfer protocol used to send and receive files and back to your website. This feature is May or May not be important to you, depending on whether you want a file server to anonymous people over this protocol. Most web sites today to submit files via HTTP through your website, which allows you to access and manage users through your website, instead of using an FTP account.

8 Database

database server is a package of data structures in an easy to store and retrieve method. Database is one of the items used to create dynamic web pages such as content management systems and blog engines. You will want to use a database if you intend to make any ecommerce site to store user data, catalogs of items for sale and purchase.

MySQL is available on most web hosting packages, whether it is on UNIX or Windows. MySQL is open source and does not require user licensing, so it usually offers more copies available to your account. This is important so that you can have a separation of data within your website. For example, your website can have a database system for content management, blog CMS, the items for sale catalog and shopping cart application. You can push all those applications use an example within the database, but you May have compatibility problems if one of those applications requires a special database connection, or table name collisions between applications. Divide cases between applications is also a security risk, since one part of your web site can be hacked expose all the data stored, including users of financial information. If you have multiple sites, then these problems, crashes and security risks will be compounded. Separating applications into different database instances is important.

MSSQL is available on most Windows hosting package, but is usually more expensive because of its business licensing restrictions, and typically has a lower case and disk space. However, some web applications are built to the advantage of its feature set, so May require this as your database. I can still use MySQL with as many applications as you might, there is no reason why a web site can use several different databases.

MSAccess is openly available database for Windows, which is more than a database file level, not the server is running. This will provide convenient storage easier to use, but it would not be enough for any large data storage needs.

The research needs of the applications you intend to run on your website, database and planning required for each will drive you to the conclusion that hosting package for use on the basis of these results.

9 Control Panel

board will be a place that will manage every detail of your web hosting account. All service providers give you a web control panel that is easy to use and provide enough help in the understanding of all of its features, so you can avoid them call for help.

web hosting providers will differ in the type of control panel they provide, however. Two main control panels are cPanel and Plesk, which is located at about 80% of providers.

Cenotes are sinkholes basis. In the Yucatan peninsula, they usually caves that have become flooded causing the roof to collapse, which often reveals the almost perfectly circular hole in the sky above the animals and giving people easy access to the water below.

What about water? Cenotes are not only filled with fresh water, they are full of rainwater that filters through surrounding vapnenačkim.Rezultat water is so clear, it seems impossible. Yes, you can clearly see all the way to the bottom of the cenote (except for those that are 500 meters deep), but also you can not see anything swimming in the water (people, fish, turtles) with amazing (and somewhat scary) clarity.

as cenotes great way to cool off, and we jumped on them as often as possible. Driving any road in the Yucatan peninsula and you'll probably see a hand-painted signs with names on them cenotes along with crude arrow path to it. For a few pesos a property owner will allow you to swim. Some cenotes are built with a ladder and snorkeling equipment rental and others are left pretty much in the way had been found. They are all refreshing and beautiful.

We even went scuba diving in Dos Ojos (two eyes) s. Since the Cenote cenotes are not fully closed as intact cave, cenote diving is considered less extreme and less danger of cave diving. We are here to tell you that this is still a wild experience whatever you call it.

As we said, water in the cenote is a hyper-clear-so clear that when you dive into it sometimes seems like the air, not water. It is also very dark once you swim back to the cenote chambers, the last places where the roof collapsed, leaking light. And a little claustrophobic.
