Let me try to describe it with an example.

I want to install munin-1.2.6 from its tarball, so I downloaded its tarball version from their official website ( http://downloads.sourceforge.net/munin/munin_1.2.6.tar.gz?modtime=1213233975&big_mirror=0)

Quote:

We need the spec file to build rpm from the tarballs. If we try to create rpm from the downloaded tarball, we get an error similar to that of the following:

error: Version field must be present in package: (main package)
error: Release field must be present in package: (main package)
error: Summary field must be present in package: (main package)
error: Group field must be present in package: (main package)
error: License field must be present in package: (main package)

The above error message means the tarball is missing a proper spec file. We need to create the spec file manually or search for it in their official website. For easiness, I am downloading it from the web itself:

Then, open the spec file and make the needed modifications. Initially, I received the error “error: Legacy syntax is unsupported: copyright” while trying to compile which is corrected by replacing the word “copyright” by “License” in the spec file. Also, change the version information to 1.2.6 in the mentioned spec file

Then create the tarball again from the mentioned directory

Then, I was able to compile the source and binary munin rpm via

Sometimes , it can show errors like the following while compiling the rpm:

It can be corrected by adding the following lines in the spec file

I do get sick of seeing all the identically base design on motorcycles, I can understand it on racers, as they are honed to race, but a road bike has so much more breadth for design possibilities depending on lifestyle. I just love this Honda Cbr1000rr bike model, it makes me very happy when a design works, and at the same time, absolutely ignores convention.

As per our design, it will be equipped with a cooled motor to air from 200cc with a freedom for the lean angle; specially tuned Showa sports suspension, including 43mm inverted front forks;;a bike full of purpose , handling and a unique feel. Above all else it will be a bike that will offer a cost-effective hugely rewarding riding experience . I’m expecting the basic model to be completed within September 2009.

I don’t have much idea about how this design affects the mileage and performance (the dry weight will be less than 150kgs) , as I am still learning about it. If you are an expert in bike modelling and want to know more about the design, please email me sumith@sumith.net and I’ll get back to you.

The term domain name has multiple related meanings:

* A name that identifies a computer or computers on the Internet. These names appear as a component of a Web site’s URL, e.g. en.wikipedia.org. This type of domain name is also called a hostname.
* The product that domain name registrars provide to their customers. These names are often called registered domain names.
* Names used for other purposes in the Domain Name System (DNS), for example the special name which follows the @ sign in an email address, or the Top-level domain names like .com, or the names used by the Session Initiation Protocol (VoIP), or DomainKeys.
* They are sometimes colloquially (and incorrectly) referred to by marketers as “web addresses”.

This article will primarily discuss registered domain names. See the Domain Name System article for technical discussions about general domain names and the hostname article for further information about the most common type of domain name.

For those of you that are not running RPM-based distros, you’re probably feeling a bit left out. Up until now, all of my tutorials have dealt with upgrading RPM-based distros. Well, that ends here. I’m going to walk through the fairly simple process of compiling and installing XCache for httpd from the original source.

The current stable release of XCache is 1.0.3. The “Unstable” release, made for PHP 5.1 & 5.2, is 1.2.0. Despite the label, I have not found anything “unstable” about the 1.2.0 version. That said, there have been a few issues reported on the vBulletin forums for users of PHP 4. If you are running PHP 4, I’d recommend that you use 1.0.3, just to be safe. Now, down to the work.

Assuming that you already have a full development environment on your system (gcc, gcc-c++, make, php-devel, etc.), the first thing you’ll need to do is to download the source tarball to your computer. Pick the version you want and then continue to the next step.

XCache 1.0.3 - PHP 4.x
XCache 1.2.0 - PHP 5.1 & 5.2

Once you’ve downloaded the source pacakge to your server, unpack it and then enter the “xcache” directory that was just created. At this point, you’ll want to run the following commands. Even a slow system should be done within 1 or 2 minutes, so don’t go anywhere.

    * phpize
    * ./configure –enable-xcache –enable-xcache-optimizer
    * make
    * make install

The output of “make install” is very important as it lets you know where the compiled module was installed. Make sure that you remember or write down that string.

Now that the xcache.so module is installed, you’ll need to configure it. If your install of PHP parses the /etc/php.d/ folder then you should create a file in that folder called “xcache.ini”. If not, just open your php.ini file and paste in the following:

[xcache-common]
    zend_extension = /usr/lib/php4/xcache.so

    ; required for >=php5.1 if you turn XCache on
    auto_globals_jit = Off

    [xcache.admin]
    xcache.admin.user = “admin”
    ; paste the output of md5(”password”) below
    xcache.admin.pass = “”

    [xcache]
    xcache.size = 32M
    xcache.count = 1
    xcache.slots = 8K
    xcache.mmap_path = “/dev/zero”
    xcache.cacher = On
    xcache.optimizer = On

Based on your configuration, you may want to make a few changes. If “/usr/lib/php4″ was not where “make install” claimed to have installed the xcache.so module, change it. Likewise, if your system has multiple processors (count logical cores from Hyper-Threading), change the value of “xcache.count”. Finally, if you plan to use the web admin interface, you’ll need to fill in “xcache.admin.pass”. This value should be a MD5 of the password you want to use (if you need an MD5 generator, try this one).

If you filled in the password, you should also copy the contents of the “admin” folder from the “xcache” source folder to somewhere web-accessible. No changes need to be made and the “config.php.example” file should be left as-is.

At this point, all that’s left is to restart httpd and you should be good. Check your phpinfo() once you’ve restarted httpd to make sure that xcache is listed.

If you want to replace a string ‘gmail’ with ‘hotmail’ in all the files under a folder, say ’sumith’ , then go under the folder sumith, then issue command

replace gmail hotmail — *

If you want to replace the string ‘aol’ with ‘yahoo’ in just a single file say ‘techie’, then issue the command

replace aol yahoo –techie

Ventrilo is a proprietary Voice over IP program with clients for Microsoft Windows and Mac OS X. Most users of Ventrilo use a headset or microphone and use the program to talk freely to each other, similar to a telephone conference call. Ventrilo is often used by multiplayer computer game players.

Game servers can be classified as listen servers and dedicated servers. Listen servers are run on the same machine as the game client. When the client disconnects, the server is shut down, as the server and host client are run together. Listen servers usually cannot support many players, due to bandwidth and CPU requirements. The software running the listen server typically limits the number of players for this very reason.

TeamSpeak is proprietary Voice over IP software that allows users to speak on a chat channel with other users, much like a telephone conference call. A TeamSpeak user will often wear a headset with an integrated microphone. Users use the TeamSpeak client software to connect to a TeamSpeak server of their choice, from there they can join chat channels.
