Chaza into ye-VPN ngaphambi kokukhetha i-SNMP noma i-API

Izinqumo ezintathu ziza ngaphambi kokuthutha: iyiphi into echazwa isixwayiso, isiphi isiqondiso nendawo esiyihlanganayo, nokuthi ukufundwa kufanele kube kusha kangakanani. I-SNMP, i-API ye-HTTPS kanye ne-probe yohlelo lokusebenza konke kungabika okuthile nge-VPN, futhi ngeke kubike into efanayo. Ukushintsha amaphrothokholi ngaphandle kokuxazulula lezo zintathu kushintsha kuphela lapho ukudideka kuqoqwa khona. Into nencazelo yesixwayiso wukwakheka; iphrothokholi wukulethwa.

Idashibhodi ephendula ukubonwa okune okuhlukene kube uphawu olulodwa oluluhlaza isivele yathatha leso sinqumo kabi.

Isixwayiso kufanele sisho ukuthini ngempela?

Kungase kusho ukuthi umpetha akakwazi ukuqinisekisa, akukho simo sedatha esivikelwe, umzila ukhomba endaweni engalungile, noma uhlelo lokusebenza alukwazi ukuqeda umsebenzi walo. Ngakunye kwalokhu kune umnikazi wakho, ukuhlola kwakho kokuqala kanye nezinga lakho lamanga-avumayo. Umpetha ongakwazi ukuqinisekisa uyinkinga yobuwena, ukuxhumana kwezokuphepha okungekho kuyinkinga yesimo sephrothokholi, umzila uyinkinga yokuhlelwa, futhi ukwehluleka kohlelo lokusebenza kungase kungabi kukho konke lokho. Nquma ukuthi isixwayiso sengakanani ngaphambi kokukhetha umqoqi.

Kubhale njengomusho injiniyela okusemsebenzini angasebenza ngawo. Uma umusho udinga izinto ezimbili, yizixwayiso ezimbili, hhayi esisodwa esilungile ngengxenye.

Ithebula le-TCP lichaza i-TCP

I-RFC 4022 icacisa i-tcpConnectionTable, okuyimigqa yayo echaza ukuxhumana kwe-TCP okusunguliwe, okuboshwe ngohlobo lwekheli, ikheli kanye nembobo kuzo zombili iziphetho. Imigqa iyanyamalala lapho ukuxhumana kuvalwa, futhi amasokhethi alalelayo avela kwelinye ithebula. Ukusebenzisa i-VPN ebhokisini elilodwa akuguquli ithebula le-TCP libe uhlu lwezokuxhumana zokuphepha ze-IPsec. Lingachaza isikhathi sokuphatha, ukugeleza kohlelo lokusebenza, noma ithumbu elithwalwa nge-TCP, futhi umugqa ngokwawo ngeke ukutshele ukuthi yikuphi.

Izibali ze-interface zithwala ukungaqondakali okufanayo ezingeni elikhulu: amabhayithi ku-interface ahlanganisa wonke umpetha nakho konke ukugeleza okusebenzisayo.

Yakha isivumelwano esincane sokubona

Kumethrikhi ngayinye, rekhoda into noma insimu ye-API esekelwayo, idivayisi enomnikazi kanye nenguqulo yesoftware, isihlonzi sompetha noma sesevisi, isiqondiso, isikhathi sokuqoqa kanye nokuziphatha kokuvuselela okulindelekile. Bese usebenzisa umbono obhalisiwe wokuxhumana noma wezikhathi wesango sesimo sephrothokholi, ithebula lomzila sesimo sendlela, kanye nesicelo esincane esivunyelwe sesimo sohlelo lokusebenza. Iphoyinti lokugcina lokuphatha elisebenzayo lifakazela ukuthi iphoyinti lokugcina lokuphatha liyasebenza, futhi akukho lutho ngohlelo lokusebenza olungemuva kwalo.

Uma i-ejenti efakiwe ingenazo izinto ezidingekayo, khetha enye i-interface esekelwe ngokusobala yokufunda kuphela. Ukuqamba i-OID, ukufunda isibali se-TCP esijwayelekile njengesibali samathumbu, noma ukulindela ukuthi i-API yomthengisi endala iqhubeke ingashintshi emkhiqizweni ongudade—konke kuyimigwaqo evalekile.

Idatha endala akukona ukwehluleka kwethumbu

Isikhathi sokuqoqa esiphelayo, imininingwane yokugunyazwa ephelelwe yisikhathi noma indlela ye-API eshintshile kukhiqiza i-telemetry engekho. Lokho wukwehluleka kokuqapha kanye nesigameko esihlukile kusukela ethumbini eliwile. Rekhoda ukuthi yikuphi ukubonwa okwaphelelwa yisikhathi nokuthi nini, ukuze umsebenzi athole ukuhlola kokuqala okunengqondo esikhundleni sokusetha kabusha ithumbu. Ukuthatha sonke isikhathi esiphelayo njengokuphazamiseka kwe-VPN kufundisa abantu ukushaya indiva kokubili.

Gcina nezimvume zokuqoqa zincane. I-interface engashintsha ukuhlelwa noma isule izikhathi ithwala umngcele wamalungelo okufanele umsebenzi wokuqapha ungawutholi njengefa, futhi i-akhawunti yokufunda kuphela ngokuvamile yanele.

Ukwakheka okusizayo kubiza into, incazelo kanye nesidingo sokusha. Ukukhethwa kwephrothokholi kulandela lokho, hhayi okuphambene.
