Ukubalwa kwe-RADIUS ngokuqhathaniswa nokungena okuphumelelayo: yini efakazelwa yilowo nalowo

Imibuzo emibili ihlangana kuyo yonke ingxoxo yokukhokhiswa kwe-VPN: ingabe lo msebenzisi wayevunyelwe ukuxhuma, futhi wenzani ngempela. Eyokuqala iphendulwa ukuqinisekisa. Eyesibili idinga amarekhodi okubalwa aqala, avuselelwe futhi aphele. Ukungena okuphumelelayo kufakazela eyokuqala futhi akusho lutho ngeyesibili, yingakho ukuhlelwa kokuqinisekisa kwe-RADIUS okusebenzayo kusengakhiqiza umbiko wokusetshenziswa ongenalutho.

Imibuzo emibili ehlukene

Ukuqinisekisa kunquma ukuthi ukuxhumana kungaqala yini, futhi kubuyisela isinqumo kanye nezici ezinjengechibi lamakheli noma iqembu. Ukubalwa kurekhoda insizakalo eyalandela, njengochungechunge lwezigameko eziboshelwe eseshini eyodwa.

Zihamba ngeprotocol efanayo futhi ngokuvamile ziye kuseva efanayo, yingakho abantu bacabanga ukuthi enye isho enye.

Akukho lutho esicelweni sokufinyelela okuthwala ubude beseshini, futhi akukho lutho kurekhodi le-Stop okunquma kabusha ukuthi umsebenzisi wayefanele wamukelwe yini. Ukuwabheka njengezivumelwano ezihlukene kwenza umsebenzi wokuhlanganisa ubonakale: enye indlela idinga isinqumo, enye idinga umjikelezo wokuphila onokuqala, phakathi nokuphela.

Yini enikezwa yizinhlobo ezintathu zamarekhodi

Irekhodi le-Start livula iseshini, i-Interim-Update libika umsebenzi ngesikhathi livuliwe, futhi i-Stop liyivala. Zontathu zithwala isihlonzi seseshini ukuze umamukeli akwazi ukuzixhumanisa nomcimbi owodwa wensizakalo.

Leso sihlonzi siwukuxhumana okuwukuphela okwethenjelwayo phakathi kwazo, ngoba igama lomsebenzisi elifanayo lingaba nezikhathi eziningi zilandelana noma ngasikhathi sinye. Dizayina isitoreji sizungeze lesi sihlonzi hhayi igama le-akhawunti.

Ukwamukela irekhodi kuyinto ehlukile ekulondolozeni kahle. Ukucaciswa kokubalwa kwenqabela ukwamukela lapho irekhodi lingakwazanga ukubhalwa, ngakho impendulo ikutshela ukuthi umamukeli uthole umthwalo wemfanelo. Ayikutsheli ukuthi umsebenzi wokubika owalandela, idashibhodi noma ukuthunyelwa kwezindleko kuyisebenzise ngendlela efanele.

Kungani igama lomsebenzisi lingeyona iseshini

Umuntu oyedwa uxhuma esebenzisa ikhompyutha ephathekayo ekuseni neselula ntambama, futhi zombili izikhathi zithwala igama le-akhawunti elifanayo. I-Start efika ngaphandle kwe-Stop ehambisana nayo ayikwazi ukuvalwa ngokufuna igama nokukhetha umugqa ovulekile omdala.

Leyo ndlela emfushane iyona eyenza imibiko yokusetshenziswa ithole ubude obungenakwenzeka.

Gcina ubunikazi besiseva sokufinyelela kunethiwekhi eduze kwesihlonzi seseshini, ngoba amaseva amabili angabela inani elifanayo ezimeni ezihlukene futhi ukuhlanganisa kuphela ngesihlonzi kungahlanganisa izikhathi ezingahlobene. Lapho iseshini iphela ngendlela engalungile, inqubomgomo yokuvumelanisa kufanele inqume ukuthi iyivala kanjani, futhi leso sinqumo singesokwakha hhayi sokuhlela idatha ngesandla kanye ngenyanga.

I-PAM ingena kuphi futhi ingangeni kuphi

Isengezo sokuqinisekisa se-OpenVPN sibiza izigaba zokuqinisekisa nokuphatha ama-akhawunti ze-PAM. Isigaba se-akhawunti sihlola ukufaneleka; igama laso alisho ukubalwa kokusetshenziswa, futhi isengezo asiqhubi izingwegwe zokuvula nokuvala iseshini ze-PAM.

Amanye amamojula e-PAM RADIUS angathumela amarekhodi okubalwa ngalezo zingwegwe zesehini, futhi lokho kusebenza kuphela lapho uhlelo luwabiza ngempela.

Ngakho ukwengeza umojula onjalo esitekeni sokuqinisekisa akudali izehlakalo zokuxhumeka. Uma udinga umjikelezo wokuphila ogcwele, khetha ukuhlanganisa okuwuphethe: isengezo noma ukwakhiwa okusekelwayo okukhipha i-Start, i-Interim-Update ne-Stop lapho ukuxhumana kushintsha isimo. Hlola isimo saso sokunakekela nokuziphatha okubhaliwe lapho umamukeli engatholakali, ngoba isengezo esilahla amarekhodi buthule sibukeka sifana ncamashi naleso esingakaze siwathumele. Ukucaciswa kokubalwa kuchaza incazelo yamarekhodi okufanele ukuhlanganisa kuyihloniphe.

Uhambo lokwamukela olufakazela isivumelwano

Hlola ukuxhuma nokuxhumeka okuvamile, bese uxhuma kabusha ngaphansi kwe-akhawunti efanayo, bese iklayenti elinyamalala ngaphandle kokuxhumeka.

Landela isihlonzi seseshini esisodwa kusukela ekwakhiweni ngokwamukela kuze kufike ekugcinweni, futhi uhlole indlela, amayunithi kanye nesixhumi esibonakalayo sezibali. Inani lamabhayithi elingenalo ilebhuli alikwazi ukucwaningwa kamuva.

Ekugcineni, qinisekisa ukuthi iseshini okwadingeka ukuthi iseva iyivale ngenxa yokuphelelwa isikhathi ivezwa ngendlela umbiko oyizwayo. Isivumelwano esihlanganisa kuphela ukuxhumeka okuhlelekile yisivumelwano esihluleka ngezinsuku oyidinga kakhulu ngazo.
