Tips to Make Your Linux VPS Work Effectively
Every Linux VPS Server has its own limit when it comes to the system resources. It is somewhat limited to about 1GB of RAM. Clients always want their VPS (Virtual Private Servers) to be fast and much responsive as possible. Below are some quick tips to make the Linux VPS Servers work effectively. Configuring MySQL cache sizes properly is one the common ways to expand the available RAM. If you noticed that your MySQL server instance is using too much memory, you can decrease the MYSQLcache sizes. And if its getting slower due to larger requests you can you can increase the chache size as per your needs. One more way to increase the performance of the Linux VPS is to disable the control panels. Everyone likes to use the most popular control panels such as Cpanel & Plesk. But if you want to free your resources you should only use the control panels when necessary. You can install them again by running a small PHP script or using shell prompt. This will free up about 120MB of RAM. Disable the unwanted features, modules and plug-ins such as Apache that are enabled in software packages. By disabling unnecessary modules or plugins will decrease the system memory that server softwares such as Apache requires, which will provide you more resources for the software that are more in need. One of the top way to make your Linux VPS responsive is to disable the system services that are unnecessarly in use. The services which are not used not only consumes RAM and CPU space but they also make your server unsecured. Apache server is a well-known for its role in the development of the World Wide Web and never been confusing to the clients. To free up the memory as per the needs check the memory apache is using and adjust the Startservers.
Six Steps to a More Secure Linux Server
I’ve worked as a remote Linux System Administrator for quite a while, and one thing that I’ve noticed is that many “administrators” out there don’t know how to configure or secure a server properly. This article is a quick reference on some of the more important (and easy) security or configuration tweaks that any administrator should do for their server. These six steps can dramatically increase the security and stability of any Linux server. The best part about these tips, is that they are all quick and easy to do as well, with each step taking less than 15 minutes!1. ) Security Updates Not Installed Nearly every server that I work on is not running the latest (and most secure) software. Yes, Linux is a great Operating System- but all software has security problems. Enabling the installation of automatic updates via a cron script or similar is the easiest and most foolproof way to ensure that your server isn’t compromised. There really isn’t any excuse not to install the latest security updates- older packages are saved in the package archives in case there is a stability or compatibility issue, and the updated packages are logged as they are updated. 2. ) Disable root login via SSH, and password authenticationAdmittedly, I’ve been guilty of this myself sometimes. Let’s face it, everyone likes being able to quickly and easily log into their servers, and change settings. However, if you’re using password authentication, what’s to keep someone else from logging into your server? In addition, you should not use password authentication on your Linux server, to prevent others from logging into your Linux server. Instead, enable RSA signed authorization keys. This is more secure, since an attacker will not be able to guess or brute force a login session with your server. 3. ) Disable or filter extra services This is the second biggest issue that I see working with new client’s servers. Often, the system administrator who setup their Linux server did not perform a necessary final step- filter incoming connections that aren’t necessary. I’ve seen everything from the daytime service running, to MySQL listening for connections on a remote IP. If a Linux administrator is not familiar with iptables, there are several tutorials out there that will show someone how to create even a basic firewall ruleset. In addition, disabling unnecessary services is a basic step in server optimization as well- why run extra services that tie up resources if they aren’t needed?4. ) Test accounts or guest accounts still activeAnother glaring security issue (and an often exploited one) is that a client will still have test user accounts running (often with extremely easy passwords, such as test) once a software solution is deployed to a production server. I don’t need to go into the security ramifications with this one- make sure that you get rid of those guest or test accounts!5. ) Advertising banners left on We all love advertising, don’t we? However, advertising to the world that the version of Apache or Sendmail that you run on your Linux server is 3 years old is not the type of attention that you want. Simply disabling the server banners will help hide your server from the basic script-dependent attackers. Besides, why help the bad guys determine what software your server is running?6. ) PHP errors or application errors I’m pretty confident that we have all seen an error or two displayed on a website. Some errors that are displayed are not a security issue at all, for instance Javascript errors. However, some errors are security issues (PHP is particularly bad with this), because they disclose sensitive information. The easiest way around this is to disable displaying errors in PHP (or your web applications). Otherwise, an attacker may be given information about your website’s database details, or file locations. These issues are the top 6 security issues that I see on a daily basis in my work. You can all check your server or servers for these quick issues (these tips take almost no time at all), and dramatically increase the security of your server. However, if you have any problems implementing these security steps, please feel free to contact me.
Using Free Resume Samples – Tips To Create The Winning Resume
The net will provide you with a number of free samples to make a better resume for yourself. Make use of these samples so that you can modify your resumes and also add twists to it or make it more contemporary. The one good thing about the free resumes on the net is that you can develop your own style, make your own resume and change the preferences and also find out from other what they think of it and also what more is needed and the things that need to be changed about it.
Many of the free resumes which have to be downloaded will get into your word processor so that it becomes easier for you to read it and also make the best use of it. If they are not being compatible with your system you can also consider downloading a word processor program which is also free and is called open office. This is a Linux based office program and a word processor that helps you open any sort of template and also download anything. This will help you a lot with your resume.
It is also considered important for you to take a good look at the many free samples of follow up letters, covering letters and also the inquiry letters. Having a covering letter that is outstanding is something which will make the employer pick your resume and also read it fully. This is very important as you need to get the job and also be called for the interview. These free samples of resumes will also many a time list the common mistakes that people tend to make when compiling their resume. There will also be strategies and tips provided to make your resume better. It will include tips for both the covering letter as well as the resume. Checking for grammatical errors and also spelling mistakes is what most of the websites miss out on letting the users know. Do not just totally rely on your computer. Do get a friend or any one trust worthy to read your resume and also check for any errors.
Do not ever use a free sample resume as your own. It may be very tempting to use one that is very close to the one you have prepared. This is a big no as there may be another person who is using the same template. Customize and make your resume look really good and also unique.
Computer Tips and Help: Buying a New Computer? Think “local”!
Technology has advanced so much during the past few years that any entry-level computer is going to have more than enough “horsepower” for the average computer user. So the days of being concerned about the size of the hard drive and speed of the processor have pretty much passed into history. RAM (memory) is still vitally important so I would not recommend any new system with less than 512MB. 1GB is even better; and if you’ve got your eyeballs set on the full, bells-and-whistles version of Windows Vista, 2GB will warm the cockles of Mr. Gates’ heart. One topic I always encourage when giving out computer tips and help to shoppers is to purchase locally, if at all possible. Virtually every community has one or more reputable computer shops that build computers. There are many advantages of purchasing locally as opposed to going through mail order or online through Dell, Gateway, HP, Compaq, etc. First and foremost, service is generally outstanding. A retailer that builds your computer will typically provide extraordinary service and support for all your computer problems, answers them in a timely manner, and realizes that their future business depends on their reputation within your local community. I usually purchase two new systems a year, each one built for me by a local computer builder/retailer. I’ve experienced first-hand through the years that if I have computer problems, answers are found quickly, with minimal or no “down” time, no 800-number calls to Banglagore, no bureaucracy, no messages that let me know how important my call is, only to advise me that my approximate waiting time is 37 minutes. In addition, many local computer builders will deliver and install your new system. Some will even copy data from your old computer to the new; and some will include an hour of training so they can show you how to use the CD-DVD burner or answer any questions you may have. But the primary benefit is cultivating a relationship with a local computer builder/repair service so that you’ll always have someone to turn to if a problem arises. If you purchase your new PC from a local retailer/builder, there’s also the benefit of keeping your hard-earned dollars right there within your community. You’ll be supporting the tax base while at the same time supporting your local merchants. How good is that?If you’re not sure who to go turn to for your new system, start making some inquiries; talk to friends, ask at local computer clubs for computer tips and help, and check the Yellow Pages and the business section of your newspaper. Keep asking and you’ll discover that there are always one or two names that continually come up. Another advantage of having a computer built for you is that you can get exactly the system you want. Or, if you’re not sure what you want, you can discuss with the builder how you use your computer and benefit from the builder’s suggestions and recommendations. When you purchase off-the-shelf or online from a national outfit, your brand-new system will generally arrive loaded with all kinds of software that you’ll probably never use. The first time you connect to the Internet, many of those programs will automatically register with their respective vendors which will open the door to pop-ups and nag screens galore, all inviting/harassing you to sign up for a variety of services, upgrades, etc. , which creates unnecessary computer problems. Answers to any issues like this will always be to buy locally. I’ve never understood the philosophy behind loading up a new computer with gratuitous software. To me, that’s like buying a new car that the dealer then drives for a thousand miles under the pretense of testing it out for you. By the time you get it home, it’s a used car! Why accept a new computer with a hard drive that’s already infested with software that you’ll never use and probably never even know what it’s for?When I purchase new computers, the only thing I permit to be installed is Windowsthough these days I prefer dual-boot Windows/Linux systems. This gets rid of many computer problems, answers all my questions about what was installed on my computer, and allows me to pick and choose what I want installed. By only permitting the operating system to be installed, and whatever drivers or programs are necessary for any peripheral devices I might purchase, I know I’ve got a squeaky clean hard drive and anything that gets installed on that computer will be installed by me. Doing this also ensures that I’ll never look at my Programs or other folders and scratch my head wondering, “What’s that program?”Another one of my computer hints, tips and recommendations is if your computer builder normally installs a plethora of programs, review a list of programs beforehand and tell the builder which ones, if any, you want installed. It’s your computer; you should decide what’s installed or not. Once I setup my new computer, then I’ll install a few of my favorite ‘can’t-live-without-’em’ programs, and I’m good to go. You’ll find a list of Mr. Modem’s Favorite Programs in my Web-based Library. Last, but not least, when purchasing a new computer, tips and help I always give out is to obtain the original Windows installation CD. Some of the big-boy retailers won’t include the installation CD or will place a ‘restore utility’ on a drive partition, which serves no useful purpose if you experience a drive failure. Obtaining the original Windows installation CD is rarely a problem with local computer builders. In most cases, it’s automatically included, but it never hurts to mention it, just to be sure. If you ever need to reinstall Windows or if a file becomes corrupted, or if you need to reinstall a component, you’re pretty much out of luck unless you have the original Windows installation CD.

Why Linux And Windows Will Never Do Your Laundry
If a store opened across the street from Target, same relative inventory, same service, only difference everything was free, would Target survive?
Unlikely.
Yet in software. . .
“Payware” = “Freeware” (open source)
————————————–
Windows = Linux
Oracle = MySQL
MS Office = OpenOffice
Ultra Edit = PSPad
. . . the current reality is that payware and freeware compete in the marketplace head to head.
In fact, the “for pay” software continues to thrive in the marketplace despite free software that is in many cases just as good (some might claim better).
Why is this?
When you buy a pair of jeans at the store the total cost is paid in full at the time of the purchase. There are no additional costs involved that directly pertain to the manufacturer. Of course there is the on-going cost of maintaining the pants through washing. This is a totally different market that is wholly agnostic to the brand of jeans. In other words, Tide washes Wrangler’s the same as Levi’s.
With software the game is different. Only a small percentage of the total cost of software can be attributed to its development. Support and maintenance make up a sizeable chunk of the cost. The larger one scales the software the higher these costs go. There is no singular solution like Tide to deal with both Windows or Linux. Sure you copy files in both, and make directories, but the means of doing so is very different and not interchangeable like your detergent. My trivial example has not even exposed the tip of the iceberg!
So this leaves us with the issue of market share. When you have a commodity that requires so much additional and continuing service/support, market share becomes a very important factor.
Support and service for free software is anything but free. Microsoft loves to tell us (and rightly so) that TCO (total cost of ownership) between Windows and Linux is in the same ballpark. They even claim that Linux costs more, all factors considered. But the geeks at Redmond can’t have it both ways. Open Source software that can be obtained for free does not represent communism (Remember Mr. Balmer declaring this?). Communism to my understanding was never a sustaining and growing multi-billion dollar business.
If we look back as to how Microsoft dominated the market we tend to forget some key points.
* The mainframe market viewed Microsoft as a passing fad.
[The CEO of DEC wondered why in the world anyone would every want to own a computer. ]
*Microsoft was the only real game in town when it came to PC operating systems.
[Any attempts by others (DR Dos, OS2) were summarily squashed. ]
*Microsoft gave away IE in order to squash then leader Netscape.
[Who?]
*Microsoft sold early versions of Office for $99. 00 to gain market share.
[Other players at the time were selling there office suites for 3+ times that amount. Microsoft bought market share by thinking long term. After all, changing your word processor and spreadsheet are a bit dicier than changing your undies. Also, think of all of us who make a living off these products. ]
While many software vendors have come and gone, it is the open source, “here it is for free” Cowboys and Cowgirls that are here to stay and threaten the very world of “for pay” software. But what the hey, we developers are typically more enthralled by creating things than making money. I know of no other profession on the planet where not taking and reusing other peoples work is considered the sane way of doing ones job. I believe in journalism they call it plagiarism?
Linux Tips?
I’m trying a bit hard to learn the Linux OS, anyway I’m just starting to learn the bash shell commands, and moving on. I actually got NDISwrapper to work on my system (hehe, it took a while, BUT I did get it). Anyway I just wanted to know, since I am planning to switching to Linux as my main OS, or even my only. If I could get some tips from some gurus.
My Linux Distro is SuSe 10. 1.
Tips For Ideal OS Web Hosting
Have you completed designing your website? Yes, so now you are on the lookout for a web hosting company is not it? Remember, choosing the web hosting company at random will only create problem and empty your pockets. What should be done? Before choosing the web hosting company you have to chalk out a plan about the operating system that you require from the company. What does operating system mean?
Meaning of Operating System:
The operating system means the server that provides all the necessary aids required for providing your website the best possible services as per the design of your website. Which are the available servers? The commonly available servers are Windows, Linux and UNIX.
These along with the software that they are equipped with gives the maximum benefit to you. What facilities do the Windows provide? The windows are easy to operate for people who use their personal pc which is installed with any version of Windows like ME, XP, NT or similar system. In the same manner there are two other servers Linux and UNIX which are equipped with PHP, BSD which is available in two types that is free and open.
How to decide which operating system should be chosen? It depends on your need but you should also keep in mind that the hosting companies use the servers that is most in demand so if you try to choose any company explicitly you may have to forgo many facilities that are provided by the reputed companies and will have to opt for a company which in the long run may prove to be a disastrous choice. Then what is the best way out where a hosting company can be chosen which will provide all the facilities that are required?
Tips for Ideal OS in a Dedicated Web Hosting
What is dedicated web hosting? It means that the server will not be shared with anybody but the hosting company will allot the server in totality for your website. You will have full control over the server which will contain hardware required for your operating system.
The hosting company may also give additional service which will be free of cost. This way you can get more returns than your investment in the long run. What is the Operating System support available on dedicated web hosting? The basic operating system available on dedicated web hosting is open source operating system, net BSD, open BSD and free BSD. The added benefit is that all these systems are free of cost.
For a beginner it is best to choose the Windows as he will not have to worry about any technical language nor face the headache of maintaining and updating the UNIX system. But this is best if the website is for personal use.
What about the newbie who will install the website for business purpose? In that case it is better to choose the LINUX or the UNIX system which contains enough space to incorporate the expansion of the business in the long run. The technical support is also more advanced and the main advantage is, it is free of cost. So always choose the OS which is the most suitable for your website.
Top Five Linux Data Recovery Tools
Top Five Linux Data Recovery ToolsThe Linux community are fast realising that losing data is factor that happens no matter how careful you are. And it can happen easily when your upgrading you distro every 6 months. Here are the top 5 opensource linux tools out there to help the Linux community recovery the data they forgot about on t he previous distro. 1. TestDisk-PhotoRecThe most developed data recovery program on Linux, designed to recover lost partition and to make non-booting disks bootable again. Very useful when you accidentally delete when installing the latest distro. Testdisk is now joint with PhotoRec which recovers files from severely damaged or re-formatted media. 2. ntfsundeletePart of the ntfsprogs; ntfsdelete scans for files located on the delete inodes and lets you extract the files. Even though it is for a Windows system useful for those countless of people that have used knoppix to repair their failed Windows system. Now with an added tool. 3. e2retrieveA useful tool to help repair and recover data from a ext2 filesystem. can recover data from a truncated or split ext2 filesystem (in the case of a LVM with a disk that has crashed, for example) will not write onto the ext2 filesystem it is analysing, therefore it will never increase damages previously caused recovers directories, directories tree, files, symbolic links and special files with their access rights, owner and modification date4. Magic RescueA program that recovers data by looking at the headers and footers of files but using the “Magic Code”. Basically a program that you can specify the headers and footers to scan for RAW data. 5. e2undele2undel is an interactive console tool that recovers the data of deleted files on an ext2 file system under Linux. Included is a library that allows to recover deleted files by name. ConclusionThe Linux data recovery tools have a long way to go if they are to compete with some of the commercial software and even freeware on Windows. However, as we all know Linux started from humble beginings. If they could put all these tools together and add a GUI we would be looking at something very useful indeed. There are many good shareware and freeware programs out there that can help you recover your files. We recommend you test and learn first before you attempt any recovery yourself. As always most important point – Don’t save on to the disk you want to recover from!!! If your data is important leave it to the professionals. for more tips …data recovery
