Zemithwalo: iintlobo, inkcazo yenkqubo

Ayizizo zonke umsebenzisi yeenkqubo zekhompyutha mihla yonke imihla ujongene nombono "uvavanyo uxinezeleko." Ngokusisiseko, yinto eqhelekileyo ukuba ababhekisi phambili web nabo bonke abo basebenzisa iinkqubo resource-olunzulu. Noko ke, maxa wambi ulwazi ngalo mba unokuba abasebenzisi luncedo nabaqhelekileyo. Zama ukuqonda isizathu sokuba konke oku kuyimfuneko.

Layisha uvavanyo: iintlobo kunye neenjongo

Okokuqala, sifanele ukwahlula ngokucacileyo phakathi kwezi ntlobo iimvavanyo. Ngokuqhelekileyo, zingakotshwa baziindidi ezimbini: ekuhloleni ikhompyutha "intsimbi" kwi umthwalo ziphezulu okanye kakhulu kwi leqela lendlela software yovavanyo nganye (websites izinto ukuqikelela, iinkqubo ngamnye, njl ...).

Ayisafuni nakucaciswa yona into yokuba iindawo uvavanyo elidityaniswe ngqo naxa kutshekishwa impilo umncedisi, enika iinkcukacha ze web virtual iiseva, ezidaliweyo kwinkqubo yokusebenza neenkqubo ezikhethekileyo ezifana Denwer.

Inkqubo yokuhlola stress kunye nemisebenzi yabo

Njengoko ubona, ubudlelwane unamandla kakhulu. Nokuthetha "zekhompyutha", uvavanyo umthwalo inkqubo usebenzisa izixhobo ezikhethekileyo uvumela ngokwaneleyo ukuchonga iingxaki kho emsebenzini ngokuchanekileyo, ngoko ukuthetha, xa kwiimeko kakhulu. Umzekelo elula. ikhompyutha imidlalo Modern kunye neemfuno zabo ngokulula ukulayisha le nkqubo kangangokuba akukho kuphinda kusebenza kwaphela. Ngoko ke, ngaphambi kokuba ufake le software kwi khompyutha yakho, kusenokwenzeka ukuba aqhube uthotho lweemvavanyo ukuqinisekisa ukuba ingaba Akunakuba "kume" Umdlalo. Ngokutsho iziphumo aze athathe isigqibo sokuba ukufaka le nkqubo. Enyanisweni, oku kwenzeka ngokufanayo kwizicelo olubandakanya ukuqhuba izibalo entsonkothileyo zemathematika umsebenzi noyilo, njengoko umthwalo kumqhubekekisi enye RAM xa kuthelekiswa imeko eqhelekileyo le nkqubo inakho yadlula amaxesha.

Njengoko ngokuba iklasi yesibini, ukuhlola isayithi kunye nomncedisi inokufana uhlobo ndlela okubonisa ukuziphatha wabo msebenzi ngokwenene. Umzekelo, kunokuba we AT ulinganiso ngaxeshanye isicelo sokufikelela inani elikhulu labasebenzisi. Njengoko yaziwa, ngokwale mgaqo zezi DDoS-ukuhlaselwa, xa umncedisi okanye isiza abakwazi ukumelana izicelo ezininzi kakhulu. iseva uvavanyo umthwalo, okanye isiza kuya kuxoxwa banzi kamva. Kwaye ngoku uqhubeke kwikhompyutha "intsimbi". Oku kusebenza kuphela ukuba ikhaya lakho okanye ezinjengeetheminali ofisi, kodwa ke eyona ngokwasemzimbeni iinkqubo umncedisi.

benchmark

Masiqalise entliziyweni nayiphi na ikhompyutha - i CPU. Ngoko ke akukho mfihlakalo ukuba ingxaki ngomsebenzi wakhe uninzi amatyala, kukhokelela imiphumo kakhulu ebuhlungu. amaxesha amaninzi oku kubangelwa nobushushu. zemithwalo ikuvumela ukuba adale iimeko ezimbi. Kwaye ngoko ungabona indlela kuya kuchaphazela umsebenzi wakhe.

Ayisafuni nakucaciswa yona ukuba ukubanjwa kwalo hlobo uvavanyo xi kubandakanya ukusetyenziswa izixhobo ezithile. Namhlanje, ukuba bakwazi ukubala amakhulu amawaka. Kodwa ke, ngokutsho iingcali ezininzi, inkokeli kule ndawo na isicelo Prime95 ukuba linokusetyenziswa iziqhubekisi, kunye imicu RAM. Kodwa ke ulwalathiso engundoqo - ezizezi ukuqinisekiswa CPU chipset.

Ukuba usebenzisa i eluncedo ukuqala kucetyiswa ukuba avale zonke izicelo ezivulekileyo ukukhubaza oluzenzekelayo imo kokuba ebekhe wazifihla (ukulala), ukuze kwikhompyutha oludale zicinywe ngexesha lovavanyo. Ngoku kufuneka akwazi kumqhubekekisi iimeko ezininzi engqongqo (inkqubo angenza ntoni Ayikho enye, ebeka ngokwenene chips kwiimeko ezininzi ezinzima). Uvavanyo ngokwayo luvuliwe kwi iinketho menu apho ukhetha ulwahlulo Ukuhlukunyezwa Test. Kuya zicaciswe iintlobo zemisebenzi. Eyona umdla apha uvavanyo Uxubo (umthwalo ngaxeshanye kwi iprosesa kwi "RAM"), kunye FFT ezincinane FFT Esikhulu (ukwanda ekusetyenzisweni CPU ngenxa nokukhutshwa RAM).

Ukuba bahlole ukuba zemithwalo yimpumelelo? Uluvo oluqhelekileyo ayikho apha, kodwa kukholelwa ukuba ubuncinane 4:00 okanye impazamo kwindawo ukusebenza chip ayikho waphawula, eli candelo uzinzile ngokwaneleyo ukuze imithwalo ngokugqithisileyo. Kodwa yenzeka ngamanye amaxesha, ukuba ukungasebenzi ukuze kwenzeka kamva, ngoko ukuba isixa esibonakalayo ixesha kungokunivela, kubhetele ukwandisa ixesha lovavanyo ukuya kwiiyure ezingama-24 (iphutha lingaba kuvela emva kwesiqingatha usuku lomsebenzi).

Ukukhangela le inkumbulo ukusebenza

Akukho ngaphantsi ebalulekileyo uvavanyo ntshikilelo of "RAM", nto leyo imisebenzi njengoko ebizwa njalo-ulinde yesibini. Oku isicelo zivunywa Memtest86 +, leyo yeyona ilungileyo.

Ukuze isebenze ngokuchanekileyo, ngoncedo ufuna ukwenza idiski yokuqala okanye flash drive kwaye download kwi computer kwesithuthi. Emva isebenze uvavanyo malunga nokuphunyezwa kwayo ngokupheleleyo kuya kufuna ixesha elininzi. Uyakwazi ushiye nje ikhompyutha yakho ebusuku. Masaneliswe.

Nokuzimisela ukuziphatha zombini yemizobo

Ne imizobo, kakhulu, kukuvavanya sevidiyo amaqhoshana sithwalisa badla kubangela iingozi computer. Kuza kubakho inkqubo isixhobo FurMark ogqibeleleyo.

Le eluncedo uyakwazi shushu nj yemizobo inamandla kakhulu kunokuba bekuya kwenza uhlobo umdlalo-ntathu kunye neemfuno nenkqubo ngentla avareji. Njengoko yokusebenza ibonisa, iimeko ezinjalo ukuba ikhadi angaqala kuwa ixesha ukususela imizuzu eli-15 ukuya kwi-30 emva kokuqalisa uvavanyo.

Ukongeza, ungasebenzisa izixhobo ezizodwa ezilungiselelwe imidlalo ezithile. Ngokomzekelo, umntu omhle kakhulu izicelo vavanyo kufanelekile ezifana Alien vs nomzingeli, ikuba okanye into ethile elolo hlobo. Njengomgaqo, zisasazwe simahla, kwaye kusetyenziselwa ukufumanisa indlela inkqubo izakuziphatha emva kokumiselwa iphakheji umdlalo yokuqala.

Ntoni abancedisi zeemvavanyo sites

Ngoku amagama ambalwa malunga yintoni na indawo uvavanyo kunye umncedisi we web. On umba omnye (DDoS-ukuhlasela) sele utshilo. Ngoku khangela kule evela kwelinye icala.

Kuvavanya zisebenzise eli hlobo ukusa kumkhamo othile kunganxulunyaniswa kude kuse izixhobo zokuthengisa ukuqikelela ukuziphatha abasebenzisi. Umzekelo, kunokwenzeka ukuba zilinganisa imeko ukuqhuba isixa esithile (ubuninzi / incopho) abantu emnyango kwisiza, ufumanise ukuba mangaphi amaphepha ingakhangelwa, nokuba u ye-imeyile, umzekelo, kwinkqubo odola impahla, ulwazi ingasetyenziswa ukuchonga abasebenzisi, ukuvumela na umthamo channel ukubonelela ukufikelela ngaxeshanye kubasebenzisi lwesiza nangaliphi na ixesha, oko baya kufuna isiqinisekiso klk umsebenzisi ngumntu wesithathu (naprime Xa ufaka inombolo credit card), ukusebenza ngendlela kuya kuba ukuqaliswa kwe Java-applets okanye usebenzisa uqhagamshelwano https olukhuselekileyo, njalo-njalo. D.

Imibuzo ivavanya server web (software) kwaye kwasekwa imithombo Internet

Enyanisweni, phantse ingxaki ifanayo ngokwayo kunye umncedisi zemithwalo. Kambe ke akukho nje technical umba ugxininiso apha. Iimvavanyo uyakwazi ukubona ukuba abasebenzisi abaninzi babe efanayo ye IP, chaza ixesha lokuphendula kwizicelo wathumela ukufumana indlela yonke le nkqubo kudibaniso olukhuselekileyo okanye non-ekhuselekileyo basabela njani, uza kuba yintoni isantya ukufikelela kwaxa uthumela izicelo ezininzi kakhulu kwaye njalo njalo. Njl .

Kulo mzekelo (yaye ke ngoko indawo, kunye neseva Web), abaninzi bacetyiswa ukuba usebenzise impahla enamandla ekuthiwa OpenSTA (System Architecture Test), nto leyo evumela nje kuphela uvavanyo, kodwa kwakhona ukuba ndimaphule ingxaki ibe components isiqalelo ngasinye ngamnye isakhiwo usebenzisa isixhobo indalo kunye Ukulinganisa izikripthi Modeler. Kuyaphawuleka ukuba emva kokuba indalo le modeli, ungakwazi noba hlola uqhagamshelwano (SSL kufuneka isonokungasebenzisi ekuthiwa-server igama). Ukongeza, iziphumo kunokugcinwa kwicandelo Umamkeli Repository, kunye iimvavanyo zidibene kumaqela afanelekileyo.

Yintoni umphumo?

Enyanisweni, oku sisishwankathelo esifutshane kakhulu imiba uvavanyo ntshikilelo, kuba iimvavanyo ngokwabo, kwakunye neenkqubo eziya kubavumela ukuba bachithe, unako ukufumana kakhulu. Yibeke ngale ndlela: Kukho izixhobo ezininzi ezithandwayo kunye ingqalelo kakuhle eli phephancwadi. Ndicinga ukuba, emva kokufunda lonke umsebenzisi a advance encinane ukuqonda imiba enxulumene novavanyo umthwalo.
