Incazelo kanye nokuchazwa kwe-Network Ping
I-Ping yigama lensiza evamile yesofthiwe esetshenziselwa ukuhlola uxhumano lwenethiwekhi. Ingasetshenziselwa ukucacisa uma ngabe idivaysi esilawuliwe-njengewebhusayithi noma iseva yemidlalo-ingafinyelelwa kunanethiwekhi yonke futhi uma kunjalo, i- latency yokuxhumana.
Amapayipi we-Ping ayingxenye ye-Windows, i-MacOS, i-Linux, namanye ama-routers namaduduzi wegeyimu. Ungalanda amanye amathuluzi we-ping kusuka kubathuthukisi benkampani yangaphandle futhi usebenzise amathuluzi kumafoni namathebulethi.
Inothi : Abathandi bekhompuyutha basebenzisa igama elithi "ping" ngokubambisana lapho beqala ukuxhumana nomunye umuntu nge-imeyili, umlayezo osheshayo, noma amanye amathuluzi e-intanethi. Nokho, kuleso simo, igama elithi "ping" lisho nje ukukwazisa, ngokuvamile ngokufushane.
Amathuluzi we-Ping
Izinsiza eziningi zamathuluzi namathuluzi zisebenzisa i- Internet Control Message Protocol (ICMP) . Bathumela imilayezo yesicelo ekhelini le-network target ngezikhathi ezithile futhi ulinganise isikhathi esithatha ukuze umyalezo wokuphendula ufike.
La mathuluzi ngokuvamile asekela izinketho ezifana nalezi:
- Zingaki izikhathi zokuthumela izicelo.
- Yeka ukuthi umlayezo omkhulu wesicelo ungathumela kanjani.
- Kuyoze kube nini ukulinda impendulo ngayinye.
Ukukhishwa kwe-ping kuyahluka kuye ngokuthi ithuluzi. Imiphumela ejwayelekile ifaka phakathi:
- Ikheli le-IP lekhompyutha ephendulayo.
- Ubude besikhathi ema-millisecond phakathi kokuthumela isicelo nokuthola impendulo.
- Inkomba yenombolo yezintambo zenethiwekhi phakathi kwama-computer acela futhi aphendulayo.
- Imilayezo yephutha uma ikhompyutha ehlosiwe ingaphenduli.
Ukutholaphi Amathuluzi we-Ping
Uma usebenzisa i-ping kukhompyutha, kunemiyalo ye- ping esebenza ne- Command Prompt ku-Windows.
Ithuluzi elilodwa elibizwa ngokuthi i-Ping lisebenza ku-iOS ukufaka i- URL noma ikheli le-IP. Inikeza amaphakethe amanani athunyelwe, athola, futhi alahlekile, kanye nesilinganiso esincane, esiphezulu, nesilinganiso esithathiwe ukuze sithole impendulo. Uhlelo lokusebenza oluhlukile olubizwa nge-Ping, kodwa nge-Android, lungenza imisebenzi efanayo.
Iyini i-Ping of Death?
Ngasekupheleni kuka-1996 nasekuqaleni kuka-1997, ukwehluleka ekusetshenzisweni kwenethiwekhi kwezinye izinhlelo zokusebenza kwaziwa kakhulu futhi kwasakazwa ngabaduni njengendlela yokusebenzisa ama-computer ahlasele. I-"Ping of Death" yayiyinto elula ukuyenza futhi iyingozi ngenxa yemiphumela ephakeme yokuphumelela.
Ukukhuluma ngokusemthethweni, ukuhlaselwa kwe-Ping of Death kuhilele ukuthumela amaphakethe we-IP wesayizi omkhulu kunama-bytes angu-65,535 kumakhompyutha athile. Amaphakethe we-IP alobu bukhulu abukho emthethweni, kodwa umqambi angakha izinhlelo zokusebenza ezikwazi ukuzenza.
Amasistimu asebenza ngokucophelela akwazi ukubona futhi aphathe ngokuphepha amaphakethe we-IP angemthetho, kodwa abanye behlulekile ukwenza kanjalo. I-ICMP ye-ping utilities yayivame ukufaka amandla okupakisha enkulu futhi yaba amagama okuthiwa yi-nkinga, nakuba i- UDP namanye amaphrothothi ase-IP nawo angahambisa i-Ping of Death.
Abathengisi bezinhlelo zokusebenza basebenzise ama-patches ngokushesha ukuze bagweme i-Ping of Death, engasabe isongela amanethiwekhi wekhompuyutha yanamuhla. Noma kunjalo, amawebhusayithi amaningi agcine umhlangano wokuvimbela imilayezo ye-ping ye-ICMP kuma-firewalls ukuze agweme ukuhlaselwa okufanayo kwenkonzo .
