RRAS DHCP: ikheli elisha noma izinketho zokuhlela kuphela?

I-ACK kuthrekhi ye-VPN ifakazela impendulo, hhayi ukwabiwa. I-RRAS ingaba nomnikazi wekheli kuyilapho i-DHCP iletha izinketho kuphela kuklayenti exhunyiwe.

Ukufunda i-DHCPACK ekubanjweni njengobufakazi bokuthi iklayenti le-VPN lathola ikheli lalo ku-DHCP kuyiphutha. Ngokuvamile ifakazela kuphela ukuthi umyalezo othile we-DHCP waphendulwa. I-Windows RRAS inganikeza amakheli eseshini kusukela echibini layo eliqinile kuyilapho i-DHCP isahlinzeka ngezinketho kuklayenti exhunyiwe. Uhlobo lwesicelo lukutshela ukuthi yimuphi kule misebenzi emibili owawuqhubeka.

Imisebenzi emibili ehlanganyela uhlobo lomlayezo

I-DHCP yenza izinto ezimbili ezihlukene, futhi zihlanganyela izinhlobo zemiyalezo. Okunye ukwaba ikheli nesivumelwano sokuqasha. Okunye ukuletha ukuhlela kumsingathi osevele unekheli, lokho i-RFC 2131 ekubiza nge-DHCPINFORM. Impendulo esimweni sesibili ithwala izinketho futhi ayithwali sikhathi sokuqasha.

Ngakho i-ACK iwubufakazi bempendulo, hhayi ubufakazi bokwabiwa. Umyalezo owandulelayo unquma ukuthi wawubuphi umbuzo obuziwe. Funda umugqa wesicelo kuqala futhi ingxenye esele yethrekhi ngokuvamile iyazichaza.

I-RRAS ithola kuphi ikheli

I-RRAS inesinqumo sekheli le-VPN ngendlela yayo ehleliwe yokwaba i-IPv4: kungaba iseva ye-DHCP noma ichibi lamakheli eliqinile. Uma ichibi liqinile, ichibi liwukwaba, futhi ukubekelwa eceleni kuseva ehlukile ye-DHCP akunazwi kuleso seshini. Izindlela zombili zingaba khona ndawonye kunethiwekhi eyodwa ngaphandle kokuthi enye ilawule enye.

Thola indlela yokwaba esebenzayo ngaphambi kokuphenya ikheli. Uma kuyichibi eliqinile, ububanzi be-DHCP buyindawo engalungile okufanele ibhekwe. Umyalo ongenhla uhluza ama-cmdlet atholakala enguqulweni oyisebenzisayo, futhi lokho kwanele ukuthola isilungiselelo.

Isigaba somsebenzisi singafakazela ini futhi singakwazi ukufakazela ini

Isigaba somsebenzisi se-DHCP iwuchungechunge oluthunyelwa yiklayenti, hhayi ubulungu beqembu obuqinisekisiwe. Ngisho noma iklayenti lithumela olunye futhi iseva iqondanisa inqubomgomo ngalo, ilebuli ifakazela kuphela ukuthi uchungechunge lwafika. I-RFC 3004 isho ngokusobala ukuthi le nketho ayiqinisekisi ilungelo lesigaba.

Ungalindeli ukuthi igama lomsebenzisi le-VPN, isihlonzi seqembu lokuvikeleka noma ikheli le-Ethernet lekhompyutha ephathwayo kuzovela kuleso sicelo ngendlela esebenzisekayo. Lokho kungamaqiniso okufakazela nokuhlu lwemibhalo, futhi isicelo se-DHCP asikuthwali kokubili. Uma imfuneko iwukwehlukanisa abantu abagunyaziwe, kusebenzise enqubomgopweni ye-VPN lapho ubunikazi bukhona ngempela. Lokho kwehlukana yikona okugcina izinhlelo ezimbili zizimele.

Qhathanisa ubufakazi, hhayi i-ACK

Akha uchungechunge lobufakazi esikhundleni sokufunda iphakethe elilodwa. Bhala phansi ikheli elatholwa iseshini, uhlobo lomlayezo nezinkambu zesicelo, izinketho ezabuyiswa yiseva, bese kuba ukuhlela kwangempela kweklayenti. Ikhonkco ngalinye liphendula umbuzo ohlukile, futhi ikhonkco elingekho yilapho iphutha langempela livame ukuba khona.

Uma ikheli livela echibini le-RRAS, ukubekelwa kwe-DHCP akuchazi lutho. Uma izinketho zafika kodwa iklayenti lazishaya indiva, iseva yenza umsebenzi wayo futhi isigaba esilandelayo ukuhlela kweklayenti. Qhathanisa leyo miphumela emibili ngokusobala, i-ACK ayisabi nokungacaci. Ithrekhi ezimbili, eyodwa kusukela endleleni ngayinye yokwaba, ziqeda ingxabano ngokushesha kunanoma yimuphi umbhalo.
