Inkcazo kunye Nenkcazo ye-Network Ping
I-Ping ligama le-software esebenzayo esetyenziswayo ukuvavanya ukuxhunywa kwenethiwekhi. Ingasetyenziselwa ukuchonga ukuba isistim esikude-njengeziko lewebhu okanye umncedisi wezemidlalo-singafikelela kwi-intanethi kwaye ukuba kunjalo, i- latency yoxhumo.
Izixhobo zePing ziyinxalenye ye-Windows, i-macOS, i-Linux, kunye nezinye iirhutha kunye neengqungquthela zemidlalo. Unokukhuphela ezinye izixhobo ze-ping ezivela kubakhi bezithathu kunye nokusetyenziswa kwezixhobo kwiifowuni nakwiipilisi.
Qaphela : Abaxhasi bekhompuyutha basebenzisa igama elithi "ping" ngokolwimi xa beqala ukudibana nomnye umntu nge-imeyile, umyalezo osheshayo, okanye ezinye izixhobo ze-intanethi. Ngaloo ndlela, igama elithi "ping" lithetha ukuxelela, ngokuqhelekileyo.
Izixhobo zePing
Uninzi lwezixhobo kunye nezixhobo zisebenzisa iProsoft Control Protocol Protocol (ICMP) . Bathumela imiyalezo yesicelo kwidilesi yechungechunge yeethagethi ngezikhathi ezithile kunye nokulinganisa ixesha elithathayo ukuba umyalezo wokuphendula ufike.
Ezi zixhobo zixhasa ngokukhethwa kukho oku:
- Mangaphi amaxesha ukuthumela izicelo.
- Inkulu kangakanani yomyalezo wesicelo ukuthumela.
- Kuze kube nini ukulinda impendulo nganye.
Imveliso ye-ping ihluka ngoxhomekeke kwisixhobo. Iziphumo eziqhelekileyo ziquka:
- Idilesi ye- IP yekhompyutha.
- Ubude bexesha kwiimillisecond phakathi kokuthumela isicelo kunye nokufumana impendulo.
- Inkcazo yenani leenethwekhi phakathi kwezicelo zeekhompyutha kunye nokuphendula.
- Impazamo yephutha xa ikhomputha ejoliswe kuyo ayiphendulanga.
Kuphi ukufumana iiTable Tools
Xa usebenzisa i-ping kwikompyutha, kukho imiyalelo ye-ping esebenza ne- Command Prompt kwi-Windows.
Esinye isixhobo esibizwa ngokuba yiPing isebenza kwi-iOS ukuba idibanise nayiphina i- URL okanye idilesi ye-IP. Inika iipakethi ezithe zithunyelwe, zifunyenwe kwaye zilahlekile, kunye ncinane, ubuninzi, kunye nexesha eliqhelekileyo elithathayo ukufumana impendulo. Insiza eyahlukeneyo egama linguPing, kodwa kwi-Android, inokuyenza imisebenzi efanayo.
Uphi Ubomi Bokufa?
Ekupheleni konyaka ka-1996 nakwiminyaka yokuqala ka-1997, ukungaphumeleli ekusebenziseni inethiwekhi kwezinye iinkqubo zokusebenza kwaziwa kakhulu kwaye kwapapashwa ngabagculi njengendlela yokuqhubela iikhomputha. I-"Ping of Death" yahlaselwa lula kwaye yingozi ngenxa yokufikelela kwayo ephakamileyo.
Ukuthetha ngokusemthethweni, ukuhlaselwa kwePing of Death kuhilele ukuthumela iipakethi ze-IP ezibukhulu obukhulu kunama-65,535 bytes kwikhompyuter ejoliswe kuyo. Iipakethi ze-IP zalesi sikhulu asikho mthethweni, kodwa umprofeti angakha izicelo ezikwazi ukuzenza.
Iinkqubo zokusebenza ezicwangcisiweyo ngokufanelekileyo ziyakwazi ukujongana nokukhusela iipakethi ze-IP ezingekho mthethweni, kodwa ezinye zahluleka ukwenza njalo. I-ICMP i-ping utilities yayivame ukubandakanya i-packet enkulu kwaye ibe yi-namesake yengxaki, nangona i- UDP kunye nezinye iiprotoksi ezisekelwe kwi-IP nazo zinokuthutha iPing of Death.
I-system yokusebenza yabathengisi baqulunqa ngokukhawuleza iipatches ukuze bagweme iPing of Death, engasayi kusongela amanethiwekhi ekhompyutha namhlanje. Sekunjalo, ezininzi iiwebhusayithi ziye zagcina iindibano zokuvimba imiyalezo ye-ICMP kwi-firewalls ukuze iphephe ukuphika okufanayo ukuhlaselwa kweenkonzo .
