A new: “MPD”

Wiki.pngMPD in computer science is an acronym for "Music Player Daemon”, a first for the world of computing.

So far we have been accustomed to think of the player as audio programs monolithic, potentially also very heavy, which take charge of all operations related to audio files. To cite a few examples "Windows Media Player”, “iTunes”, “Amarok”, “Exaile”. All these programs create a playlist by listing the contents of one or more folders inside the pc, and possibly by organizing them according to the data stored within (as is the case with the EXIF ​​data of the photo), I play and eventually equalize (plus some optional feature such as the management of the covers, i test, purchase tickets, etc..).

Use the file “.htaccess” per bloccare l’hotlinking

broken_link.jpg We continue to talk about ".htaccess”, Today we see how block hotlink to images that reside on our server.

Yesterday we talked about as to prohibit access to our images from external sites (as often happens with forum the amateur sites), that do nothing but increase the use of the band, reducing the resources of our server. In the case of yesterday, the user will see the symbol of missing image, those who try to connect directly to the site I get the error "403 Forbidden”.

Today we want to have fun instead. Would not it be funny if the user instead of seeing the image missing seeing another image that urges him to do not link from our server? This time we will create a file ".htaccess"Directly in the images directory. And 'possible to create more ".htaccess"On a server. If you can create one for each directory. Let's see how it will be our for images:

Use the file “.htaccess” to block the access

googlebot1.jpg For anyone who happened to monitor the access of a site will ever come across very similar to each other access, often it is crawler (Google itself uses a sophisticated type of crawler called GoogleBot). Paraphrasing Wikipedia:

One crawler (also called spider the robot), is software that analyzes the content of a network (or a database) in a methodical, automated, typically for account of a search engine.

Crawlers are usually harmless, create a no traffic within the site (if done well) to offer Indexing Service that we all know and appreciate. [more]

However there are crawlers that, using the same mechanisms of the crawler indexing, scanning the web looking for flaws in the code pages. As we know webmasters are not always careful in planning, and sometimes we are aware of some security breaches Site (The portal). These harmful crawlers explore the length and breadth of the web, indexing the pages for themselves in order to "pierce"The site, and have access the server or worse sensitive data.

Also, in addition to not make us a good indexing service, increase the use of the band, forcing the browser to visit the site more slowly. Well ... over insult to injury.

However, it is possible via a simple text file block access to certain IPs or "user agent" once identified. I'm talking about the file. "Htaccess".

The file ". Htaccess" is a useful configuration file to the server, a very simple tool, but equally powerful, and can not be used lightly. An error in the configuration file may inhibit the webmaster access to their pages, for which Andiamoci cautious.

The safest way to know if the "user agent"Who has made a recent visit to the site is harmful crawler is a search on Google. Let him separately "user agent” e l’IP address from which we received the request.

Locking the bot through. "Htaccess"

This example, and all subsequent, can be added at the bottom of the file ".htaccess”, always it has been created. If it does not already exist you can create it: a simple text file that we will call ". htaccess" will put in "root directory"The server.

#Let's get rid of the bot %{HTTP_USER_AGENT} ^BadBot
RewriteRule ^(.*)$ http://go.away/

What does this piece of code? Simple. The few lines above tell the server to control all access whose "user agent” beginning with "BadBot”. When it finds one that coincides redirects to an address that does not exist called "http://go.away/”.

Now let's see how to block more than one:

#Let's get rid of the bots %{HTTP_USER_AGENT} ^ BadBot [OR]
RewriteCond %{HTTP_USER_AGENT} ^ EvilScaper [OR]
RewriteCond %{HTTP_USER_AGENT} ^FakeUser
RewriteRule ^(.*)$ http://go.away/

The code above does exactly the same things that made the first, in this case blocks all "user agent"That begin with"BadBot”, “EvilScraper”, “Fake User”. Note that when there is more than one bot to lock you need to put "[OR]"At the end of the line of all the rules, except that the last.

Locking the "thieves" bandwidth

Anyone sailing usually does not know, but it often happens that to be lighter on your own server (or simple ignorance) some webmasters include images of residents elsewhere in your pages. This lightens the load on the server that does not have the burden of hosting the image, but weights traffic on the server where the image resides, not to mention that the second server has no advertising from the work done.

Since we can not afford to change in sequence the images on our website, also in this case ".htaccess"There is help.

RewriteEngine on
RewriteCond %{HTTP_REFERER} ^http://.*somebadforum\.com [NC]
RewriteRule .* - [F]

In this way "somebadforum.com"Will be redirected to a code403 Forbidden"For each image included. The end result will be the classic symbol of missing image (broken image), e nostro server-side saves SARÀ.

To lock more than one site this is the code:

RewriteEngine on
RewriteCond %{HTTP_REFERER} ^http://.*somebadforum\.com [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://.*example1\.com [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://.*example2\.com [NC]
RewriteRule .* - [F]

As above, note on the finish of each line "OR”, except for the last.

Ban the IP

It can also happen that you do clever bot, and to change their rotation "user agent”, in order to have continuous access to the pages of the site. When this phenomenon happens one way to block access to the bot "imaginative" is block IP (lock only if there is a continuous access from the same IP). Also in our trusty ".htaccess"Add the following lines:

order allow,deny
deny from 192.168.44.201
deny from 1.2.3.4
deny from 5.6.7.8
allow from all

In this example we block three IP addresses, with the last line guarantee access to all other. But it is also possible to block access to the root of the address (this is. 192.168.*):

order allow,deny
deny from 192.168.
deny from 100.29.
deny from 500.699.
allow from all

With these rules, all IP addresses that begin with "192.168.” (and the following) will be blocked.

Suggest always to create a backup of ".htaccess”, things do not always go the way we want, and would not be useful to anyone not having access to their server. The most common hoster offer support to file ".htaccess”, in case your hoster not offer such support believe is the case of cambiare hoster.

Continue carrellata di self-produced pieces. Oggi you propongo "What Can I Do?”, a piece originally produced by BrainStorming in 2004 nel even demo "4002 Omed”. The original version had some inaudible sounds, in this I changed the chorus and by the way the entry is missing.

Maybe these days I can find the piece originally recorded by brainstorming, so that you can make a direct comparison.

Domains “.co.nr” Free

logo_conr.gif As the domains with the extension ".tk"The isole Tokelau, a handful remotest islands in the Pacific, also domains with the extension ".co.nr"Are Free.

The domains ".No."Belong to the State of Nauru, in Oceania. The Flag of OFFERTA da ".co.nr"But no part of the state administration. It is actually registered the domain "http://co.nr/"Free to point to the page selected by the user registered, that will use a subdomain ".co.nr” (for example, "http://thejoe.co.nr/”. [more]

The advantage using a domain name with the extension ". co.nr" is the gratuity Domain, e la brevity they maintain, despite being a second-level domain. In addition, by registering you have access to your index page of the subdomain, and the relative ability of change description and keywords.

Fra Gli disadvantages I unfortunately can not monitor access to the site through Google Analytics. And 'possible to monitor the real domain (that hosts the site) con Analytics, but the same domain is not "monitored". Among other things, this is not a real redirect, is instead created a "iframe"At 100% the size of the page, in which is shown the site "true”.

This blog, not being a professional blog, does not require a professional domain registration, and takes advantage of the free service offered by ". co.nr".

Music: “qbsc.mp3″

thumb_tramonto.jpg After merging a small mp3 player, “1 bit audio player”, between the pages of this blog, I thought the content from me (and a few others) created, can be directly usable and downloadable.

First on the list is the now famous "qbsc.mp3”, who, after having depopulated between the cellular acquaintances now lands on the web. The reason of the name is easily understandable after listening.

I should point out that the short sound file has been realized only with open source. OS, DAW, drum machine and a mastering tool used are open source software.

The image comes from the initial blog Little Butterfly thank you.

A short will realize a page that lists all of the works.

Good listening.
