Kuyini Ping, futhi kungani kudingeka

Izwe lingenizonde ukucabanga ukuphila ngaphandle kwe-inthanethi. Izigidi zabantu uhleli ukuxhumana nomphakathi, ukudlala imidlalo inthanethi, ufuna ulwazi izinjini, wenze ukuthenga futhi ukukhokhela amasevisi. Futhi uma eminyakeni embalwa edlule mayelana isivinini kanye nekhwalithi Inthanethi safika kanini, kodwa manje ukukhetha enkulu abahlinzeki, lezi inthanethi nezinsizakalo ezimbili izinga ziqokonyiswe. Ngakho-ke, amandla kanye umzamo esichithwa nokusetshenziswa ilungise inkinga ukusebenza amanethiwekhi computer, futhi lokhu akuwona neze umsebenzi olula.

Ngokuvamile kukhona izinkinga kanye ngokungakhulumi kwezinye abasebenzisi noma eqenjini lilonke imishini. Okufanele ukwenze ke? Futhi unquma kanjani izinga umlawuli ukutholakala ISIZINDA ngabanye nakunethiwekhi izingxenye? Ngezindlela eziningi, ukucacisa isimo kungaba Ping umyalo, okuyinto ingasetshenziswa cishe yiluphi uhlelo lokusebenza. Ake sizame ukuthola ukuthi uhlobo iqembu, futhi uma isetshenziswa.

Ping umyalo inquma isikhathi esiqondile impendulo iseva eqhelile, okuyinto wathumela ICMP-amaphakheji. Sebenzisa yayo inethiwekhi abaqondisi ukuxilonga inkinga nokufinyeleleka zingxenye ngabanye noma ISIZINDA. Kodwa lokhu akusho ukuthi ingasetshenziswa hhayi abasebenzisi abavamile.

Ping Command - iyithuluzi jikelele atholakale zonke futhi nganoma isiphi isikhathi. Ngaphezu kwalokho, i-syntax ukusetshenziswa kwalo ilula kangangokuba ngisho umuntu abe ukunambitha, ongenakwenziwa asebenzelana ngayo amanethiwekhi computer. Kuhlanganisa arsenal ebanzi ongakhetha nge ongasebenzisa kuzo phambi uhlelo esinembile yokusebenza nemingcele. Esikhathini yokusebenza umyalo uhlelo Ping (i-Windows, Unix) wenziwa nje. Ukuze wenze lokhu, udinga nje uyisebenzise e isicelo ezifanele. Isibonelo, abasebenzisi Windows avele aqalise uhlelo ngokushesha umyalo bese ufaka umbhalo elandelayo: ping , lapho iyunithi olushiwo engela kubakaki, ngoba lapho uya khona ukuhlola ping. Ukuze abasebenzisi izinhlelo Unix ezisekelwe zonke izinyathelo ezingenhla yanele ukuba akhiphe esigungwini.

Ping umyalo uvame ukusetshenziswa ne ongakhetha -t, -S, -I. Eyokuqala ikuvumela ukuba ugcine ithrekhi isinyathelo imiyalo nenombolo enganqunyelwe yezikhathi (ie ping akusho kuphelelise umsebenzi wako ekupheleni ngesikhathi osinikiwe, izilungiselelo ejwayelekile). Okwesibili - ushintsho ICMP-usayizi iphakethe, okuyinto ithunyelwa ikhompyutha ethile noma iseva, futhi eyesithathu kahle - ukushintsha nesikhathi esithileko hlangana ngokuthumela lezi amaphakethe. Ungasebenzisa futhi ezinye izinketho, mayelana nokuthi iziphi izinhlelo zingatholakala ngokubiza usizo zendawo ukuze lowo myalo.

Kunengqondo ukuthi umsebenzisi elula ungase ubuze: "Indlela ahumushe imiphumela izenzo iqembu?". Ukuphendula ke, kuhle ukuthi uzinake wena ukuthi ping kunikeza umbono walokho ijubane iphakethe kunethiwekhi ekhona. Uma yedlula ISIZINDA njalo ngezikhawu ezithile, ngaphandle kuzuba njalo, liwubufakazi umsebenzi ngokunemba, kodwa uma kunjalo amaphakheji eze ephethe ukulibala eqinile noma kungekho imali, kusho ukuthi inethiwekhi kukhona ezinye izinkinga ezidinga ukulungiswa ngokuphuthumayo umlawuli ikhompyutha uhlelo.
