Haddii aad ka soo shaqeysay shabakad shirkadeed, waxay u badan tahay inaad la kulantay ereyga proxy server, waxaadna ogtahay in la'aanteed aanad geli karin mareegaha iyo adeegyada ka baxsan shabakadda shirkadda. Si kastaba ha ahaatee, waa maxay dhab ahaan server-yadani? Ma tahay inaad mid ku isticmaasho guriga? Akhri hagahan si aad u ogaatid sababta ay wakiiladu ugu baahan yihiin iyo goorta aad isticmaalayso wakiil:

FIIRO GAAR AH^(NOTE) : Waxaa jira noocyo badan oo ah server-yada wakiillada kuwaas oo sameeya wax kasta oo kala duwan. Maqaalkan, waxaan tixraacaynaa nooca ugu caansan - wakiillada webka ee fududeeya helitaanka macluumaadka iyo adeegyada laga helo internetka.

Waa maxay wakiil? Waa maxay macnaha server-ka wakiilka?

Server-ka wakiilku waa dhexdhexaadiye u dhexeeya PC-gaaga ama qalabkaaga iyo intarneedka. Seerer-kani wuxuu kuu sameeyaa codsiyada mareegaha, adeegayaasha iyo adeegyada intarneedka adiga. Fikrad la xiriirta oo mararka qaarkood lala isticmaalo server-ka wakiil waa VPN ( Shabakadda Gaarka ah ee Virtual^{(Virtual Private Network)} ). Akhri goorta la isticmaalayo wakiil iyo goorta la isticmaalayo VPN? ^{(When to use a proxy and when to use a VPN?)}si loo fahmo farqiga.

Aynu ka soo qaadno inaad shaqada ku jirto. Waxaad isticmaaleysaa biraawsarkaaga si aad u booqato www.digitalcitizen.life oo browserkaagu waxa loo dejiyay inuu isticmaalo server wakiil ah. Kadib marka aad ku qorto www.digitalcitizen.life, codsiga waxa loo diraa adeegaha wakiilka. Adeegga wakiillada ayaa markaa codsiga u soo diraya seerfarka halka lagu hayo mareegahayaga. Bogga hore ee mareegahayaga waxaa lagu soo celiyaa server-ka wakiilka kaas oo, isna, kuu soo celinaya. Natiijo ahaan, shabakadeenu waxay u aragtaa server-ka wakiilnimada inuu yahay booqdaha dhabta ah, halkii aad ka arki lahayd kombiyuutarkaaga. Xog-isweydaarsigan waxaa lagu muujiyey sawirka hoose iyadoo la raadinayo jawaabta su'aal fudud: waa maxay waqtiga hadda?

Hadda oo aad ogtahay aasaaska, aan aragno faa'iidooyinka aad ka heli karto adiga oo isticmaalaya server-ka wakiil.

Maxaa loo isticmaalaa server-ka wakiil?

Fikradda server-ka wakiilku wuxuu bixiyaa faa'iidooyin aad u tiro badan:

• Xakamee^(Control) isticmaalka internetka ee shabakadaha shirkadaha
• Kaydinta bandwidth^(Bandwidth) ee shabakadaha waaweyn
• Xawaaraha la hagaajiyay
• Qarsoodinimada
• Amniga
• In laga gudbo faafreebka

Aynu mid mid u soo qaadano dheefahaas oo aan caddayno sida ay kuugu shaqayn karaan.

Xakamee^(Control) isticmaalka intarneedka adoo isticmaalaya wakiillada

Mid ka mid ah sababaha ugu muhiimsan ee wakiillada si weyn loogu isticmaalo shabakadaha shirkadaha waa inay bixiyaan xakamaynta waxa shaqaaluhu gelayaan iyo isticmaalka internetka. Tusaale ahaan, shirkado badan ayaa mamnuuca mareegaha qaarkood si aanay shaqaaluhu u marin saacadaha shaqada. Tusaale ahaan, waxaa laga yaabaa inay mamnuucaan mareegaha dadka waaweyn, shabakadaha bulshada ee caanka ah ama mareegaha waqti lumis sida 9gag.com.

Ku qasbida shaqaalaha inay galaan internetka kaliya iyada oo loo marayo wakiilka shirkaddaada sidoo kale waxay la macno tahay inaad haysatid qoraallo faahfaahsan dhammaan mareegaha iyo waxa ku jira ee ay galeen, goorta, iyo muddada. Warbixinno faahfaahsan oo ku saabsan isticmaalka ayaa laga heli karaa shaqaale kasta, shirkadduna waxay si dhakhso ah u aqoonsan kartaa isticmaalayaasha dhaqan-xumada.

Kaydinta bandwidth^(Bandwidth) iyo xawaaraha la hagaajiyay marka la isticmaalayo server wakiil

Sababta kale ee ay shirkaduhu u isticmaalaan server-yada wakiillada ayaa ah inay ka caawiso inay badbaadiyaan xawaaraha qaaliga ah. Server-yada wakiillada ah waxay ku cadaadin karaan taraafigga, faylalka kaydinta iyo boggaga internetka ee interneedka iyo xitaa xayaysiisyada ka saara mareegaha kahor intaysan gaarin kombayutarkaga. Waxa ay u ogolaataa shirkadaha in ay badbaadiyaan bandwidth, gaar ahaan marka ay leeyihiin boqollaal ama kun oo shaqaale ah, galaan inta badan websites caan ah (tusaale, CNN , New York Times , Wikipedia , iwm).

Marka bogga shabakadda la galo, server-ka wakiilku wuu kaydin karaa, marka qofka xiga uu codsado, wuxuu marka hore fiiriyaa haddii boggu isbeddelay. Haddii aysan isbeddelin, waxay gudbisaa nuqulka maxalliga ah iyada oo aan dib loo soo dejin bogga oo dhan. Tani waxay labadaba u badbaadinaysaa xadhkaha xadhkaha ee shirkadda waxayna ka dhigaysaa habka rarka si degdeg ah qofka xiga ee codsanaya kheyraad isku mid ah.

Faa'iidooyinka qarsoodiga: qari cinwaankaaga IP-ga, goobta, iyo macluumaadka kale

Marka aad si toos ah ugu xidhan tahay intarneedka, oo aad ku shubato mareegaha, server-ka meesha lagu hayo waxa uu arki karaa ciwaanka IP-gaga. Iyada oo la kaashanayo ciwaanka, waxa ay qiyaasi kartaa goobtaada juquraafi ahaan. Sidoo kale, browserku wuxuu soo diraa macluumaadka wakiilka isticmaalaha, website-kuna wuu yaqaan browserka aad isticmaalayso. Intaa waxaa dheer, cookies ayaa lagu kaydiyaa kombuyutarkaaga, waxayna ku siinayaan macluumaad shakhsi oo dheeraad ah.

Adeegayaasha wakiilku waxay qarin karaan cinwaankaaga IP-ga (haddii loo qorsheeyay inay tan sameeyaan), waxay soo diri karaan wakiil isticmaale oo ka duwan si aan browserkaagu u aqoonsanin oo u xannibo cookies ama u aqbalo laakiin uusan u gudbin kombuyutarkaaga ama qalabkaaga. Sidaa darteed, marka aad isticmaalayso server wakiil, waxaad noqon kartaa qarsoodi badan marka loo eego markaad isticmaaleyso xiriirka tooska ah ee internetka.

Adeegayaasha wakiillada ayaa hagaajin kara amniga

Server^(Proxy) -yada wakiillada waxa kale oo laga yaabaa inay door ku yeeshaan hagaajinta amniga, gaar ahaan marka lagu isticmaalo shabakadaha ganacsiga. Waxaa loo dejin karaa inay xannibaan gelitaanka shabakadaha xaasidnimada leh ee qaybiya malware, waxayna sidoo kale bixin karaan adeegyada sirta ah si xogtaada aysan si fudud ugu urin qolo saddexaad oo doonaysa inay gacmahooda ku helaan.

Adeegayaasha wakiillada^(Proxy) ayaa laga yaabaa inay bixiyaan marin u helidda ilaha la xannibay ee shabakadda

Isticmaalka caanka ah ee adeegayaasha wakiillada ayaa ah ka gudubka faafreebka intarneedka. Tusaale ahaan, wadamada sida Shiinaha^(China) ama Iran waxay faafreeb ku sameeyaan gelitaanka shabakado iyo adeegyo badan oo internetka ah. Isticmaalayaasha wadamadaas waxay isticmaali karaan wakiilada wakiillada si ay uga gudbaan faafreebkan oo ay galaangal ugu yeeshaan iyaga.

Sidoo kale, waxa jira adeegyo laga heli karo dalal gaar ah oo keliya. Tusaale ahaan, Hulu waxay u shaqeysaa kaliya isticmaalayaasha ku saleysan Mareykanka iyo Japan . Dadka ku nool Yurub^(Europe) waxay isticmaali karaan server-ka wakiil ka ah Maraykanka si ay u galaan.

Ma isticmaali karaa server wakiil ah? Dhibaatooyinka amniga ee suurtagalka ah ee ay abuuraan adeegayaasha wakiillada.

Isticmaalka wakiillada wakiillada maaha dhammaan faa'iidooyinka iyo alaabooyinka wanaagsan. Waxay keeni karaan dhibaatooyin sida:

• Markaad isticmaalayso xidhiidhada aan qarsoodi ahayn, server-ka wakiilku wuxuu bedeli karaa jawaabaha aad hesho, labadaba siyaabo wanaagsan iyo kuwa xun. Tusaale ahaan, server-ka wakiil ee cudurka qaba ama xaasidnimada leh ayaa loo isticmaali karaa in lagu geliyo malware-ka biraawsarkaaga ama laguu jiheeyo mareegaha phishingka.
• Wakiilku waxa uu bedeli karaa codsiyada aad ka samayso mareegaha ama adeega interneedka si uu u dhaliyo natiijooyin qanciya waxa qof kale damacsan yahay.
• Adeegaha wakiilku waxa uu ilaalinayaa oo diiwaan gelinayaa hawshaada. Sidaa darteed, waxay kaydisaa macluumaad badan oo adiga kugu saabsan oo loo isticmaali karo aqoonsi waqti dambe.
• Iyada oo ku xidhan sida loo habeeyey, server-ka wakiilku waxa uu ku siin karaa xog aan la qarinin halka xogta sir ah ay hore u bixisay degelka ama adeegga aad isticmaalayso. Waxay kuu soo bandhigi kartaa dhuujinta shabkada iyo in ay dadka kale la socdaan waxa aad ka samaynayso intarneedka.

Sida loo isticmaalo server-ka wakiil ka ah kombuyuutarkaaga iyo qalabkaaga

Way fududahay in la habeeyo isticmaalka server-ka wakiil ka ah dhammaan nidaamyada hawlgalka ee waaweyn: Windows , Android , iOS, iyo wixii la mid ah. Haddii aad go'aansato inaad dejiso server wakiil, arag casharradayada si aad u hesho caawimo:

Waa maxay sababta aad u raadinayso xal server wakiil?

Sida aad arki karto, server-yada wakiillada ayaa noqon kara mid weyn, sidoo kale waxay noqon karaan dhibaato. Dhammaan waxay ku xiran tahay sida loo habeeyey, sida loo xafiday iyo cidda ay maamulaan. Adeegaha wakiilku waxa laga yaabaa inuu bixiyo dhammaan faa'iidooyinka kor lagu soo sheegay ama midkoodna. Dhammaan waxay ku xiran tahay sida loo dejiyay iyo sababta. Kahor intaadan isticmaalin server-ka wakiil ka ah, waxaa muhiim ah in la fahmo sababta aad u isticmaalayso, cidda maamulaysa server-ka wakiilnimada iyo haddii ay maamusho cid la aamini karo. Ka digtoonow server-yada wakiillada dadweynaha oo aanad waxba ka garanayn. Qaar ka mid ah wakiilada dadweynaha ayaa loo isticmaali karaa ujeedooyin xaasidnimo ah, waxayna kuu soo bandhigi karaan dhibaatooyin halkii ay ku siin lahaayeen faa'iidooyinka. Haddii aad wax su'aalo ah ama waayo-aragnimo ah la leedahay wakiilo mudan in la wadaago, ha ka waaban inaad faallo ku dhaafto xagga hoose.

Simple Questions: What is a proxy server and what does it mean?

If you have worked in a corporate network, yоu have probably encountered the term proxy server, аnd you know that without one you cannot access websites and services outside the company's network. However, what exactly arе these proxy servers? Should you use one at home? Read this guide to leаrn why proxy servers are neceѕsary and whеn you should use a proxy:

NOTE: There are many types of proxy servers that do all kinds of things. In this article, we refer to the most common type - web proxies that facilitate access to the content and services found on the internet.

What is a proxy? What does proxy server mean?

A proxy server is an intermediary between your PC or device and the internet. This server makes requests to websites, servers and services on the internet for you. A concept related and sometimes used together with a proxy server is VPN (Virtual Private Network). Read When to use a proxy and when to use a VPN? to understand the difference.

Let's assume that you are at work. You are using a web browser to visit www.digitalcitizen.life and your browser is set to use a proxy server. After you type www.digitalcitizen.life, the request is sent to the proxy server. The proxy server then sends the request to the server where our website is hosted. The homepage of our website is returned to the proxy server which, in turn, returns it to you. As a result, our website sees the proxy server as the actual visitor, rather than seeing your computer. This exchange of information is illustrated in the image below with the search for an answer to a simple question: what is the current time?

Now that you know the basics, let's see the benefits you get by using a proxy server.

What is a proxy server used for?

The concept of the proxy server offers a surprisingly large number of advantages:

• Control internet usage in corporate networks
• Bandwidth savings for large networks
• Improved speed
• Privacy
• Security
• Bypass censorship

Let's take these benefits one by one and clarify how they can work for you.

Control internet usage using proxy servers

One of the most important reasons why proxies are widely used in corporate networks is that they provide control over what employees are accessing and using on the internet. For example, many companies ban certain websites so that employees do not access them during work hours. For example, they may ban adult websites, popular social networks or time-wasting websites like 9gag.com.

Forcing employees to access the internet only through your company's proxy also means that you have detailed logs of all the websites and content that they accessed, when, and for how long. Detailed usage reports are available about each employee, and the company can quickly identify misbehaving users.

Bandwidth savings and improved speed when using a proxy server

Another reason why companies use proxy servers is that it helps them save precious bandwidth. Proxy servers can compress traffic, cache files and web pages from the internet and even strip ads from websites before they reach your computer. It allows companies to save bandwidth, especially when they have hundreds or thousands of employees, accessing mostly the same popular websites (e.g., CNN, New York Times, Wikipedia, etc).

When a web page is accessed, a proxy server can store it and, when the next person requests it, it first checks if the page has changed. If it has not changed, it forwards the local copy without re-downloading the whole page. This both saves bandwidth for the company and makes the loading process faster for the next person that requests the same resource.

Privacy benefits: hide your IP address, location, and other information

When you have a direct connection to the internet, and you load a website, the server where it is hosted can see your IP address. With the help of this address, it can approximate your geographical location. Also, the browser sends its user agent information, and the website knows what browser you are using. On top of this, cookies are stored on your computer, and they provide further personal information.

Proxy servers can hide your IP address (if they are set to do this), can send a different user agent so that your browser is not identified and can block cookies or accept them but not pass them to your PC or device. Therefore, when using a proxy server, you can be more anonymous than when using a direct connection to the internet.

Proxy servers can improve security

Proxy servers may also have a role in improving security, especially when used in business networks. They can be set to block access to malicious websites that distribute malware, and they can also provide encryption services so that your data is not easily sniffed by third-parties that want to get their hands on it.

Proxy servers may provide access to blocked resources on the web

A popular use for proxy servers is the bypassing of internet censorship. For example, countries like China or Iran censor access to many websites and services on the internet. Users in those countries can use proxy servers to circumvent this censorship and get access to them.

Also, there are services which are available only in specific countries. For example, Hulu works only for users based in the US and Japan. People in Europe can use a proxy server based in the US to access it.

Should I use a proxy server? Possible security problems generated by proxy servers.

Using proxy servers is not all about benefits and good stuff. They can pose problems like:

• When using unencrypted connections, the proxy server can alter the responses you receive, both in good and bad ways. For example, an infected or malicious proxy server can be used to load malware into your browser or redirect you to a phishing website.
• A proxy can alter the requests you make to a website or service on the internet to generate results that meet someone else's intentions.
• A proxy server monitors and logs your activity. Therefore, it stores lots of information about you that can be used for identification at a later date.
• Depending on how it was configured, a proxy server can provide unencrypted data where encrypted data was previously provided by the website or service you are using. It can expose you to network sniffing and having others monitor what you are doing on the internet.

How to use a proxy server on your computers and devices

It is easy to configure the use of a proxy server in all the major operating systems: Windows, Android, iOS, and so on. If you decide to set up a proxy server, see our tutorials for assistance:

• How to set up the proxy server settings in Windows 10
• How to set a proxy server in Chrome, Firefox, Internet Explorer, Microsoft Edge, and Opera
• How to set the use of a proxy server for WiFi, on Android
• How to set the use of a proxy server for Wi-Fi, on an iPhone or an iPad
• How to set a proxy server on Windows 8.1 tablet or hybrid device

What is your reason for looking for a proxy server solution?

As you can see, proxy servers can be great, and they can also be a problem. It all depends on how they are configured, how they are secured and by whom they administered. A proxy server may provide all the benefits mentioned above or none of them. It all depends on how it was set up and why. Before using a proxy server, it is important to understand why you are using it, who controls the proxy server and whether it is administered by a trusted party. Be wary of public proxy servers of which you know next to nothing. Some public proxies can be used for malicious purposes, and they can expose you to problems instead of providing benefits.
