Indlela yokuqalisa i-kernel ye-Wolfram ekude kusuka ku-laptop nge-VPN

Uxhumanisa i-VPN, uvula incwadi yamanothi futhi ulindele ukuthi iseli elisindayo lizogijima kuseva. Empeleni, umhubhe uhambisa amaphakethe kuphela. Awufaki isihlaziyeleli, awunikezi ilayisense futhi awukhethi ukuthi iyiphi imishini ezosebenzisa ikhodi. Lezi zinto ezintathu ezihlukene, futhi ukuhamba komsebenzi one-kernel ekude kudinga zontathu ngaphambi kokuthi ukubala kokuqala kuthembeke.

Inganekwane: ukuxhumana kwe-VPN ukulungiselela

I-VPN inikeza indlela yenethiwekhi phakathi kwe-laptop neseva. Lokho kuyasiza futhi kuvame ukudingeka, ngoba isiteshi sokuqalisa nokuxhumana kwe-kernel kufanele kufinyelele umsingathi okude. Akusho lutho mayelana nokuthi ingabe i-kernel ye-Wolfram ikhona kulo msingathi, ingabe ilayisense ivumela inqubo yesibili ngesikhathi esisodwa, noma ingabe ingaphambili lilungiselelwe ukuyisebenzisa.

I-laptop elawulwayo ingase ibe nengaphambili kuphela, kanti ilungelo lixhunywe kuseva. Okuhlanekezelwe nakho kuyenzeka: ilayisense yedeskithophu ku-laptop ayigunyazi i-kernel engqalasizindeni eyabiwe. Awekho kulezi zimo ezimbili axazululwa ngokuxhuma kabusha umhubhe.

Hlola lo mbono kusenesikhathi. Hlola i-$MachineName encwadini yamanothi entsha bese uqhathanisa impendulo nomsingathi oyilindele. Uma ibuyisela igama le-laptop, iseli lagijima endaweni, kungakhathaliseki ukuthi i-VPN ibonakala iphilile kangakanani.

Hlukanisa ingaphambili nesihlaziyeleli

Ingaphambili iwindi: lihlela amaseli, likhombisa okukhiphayo futhi ligcina ifayela lencwadi yamanothi. I-kernel inqubo ehlola izinkulumo futhi igcina izincazelo emqondweni. Ukuvala ingaphambili akukuhambisi i-kernel, futhi ukugcina incwadi yamanothi akugcini isimo se-kernel.

Lapho i-kernel ekude ixhunyiwe, indawo yefayela lencwadi yamanothi nendawo yokusebenza ye-kernel kuyizinto ezimbili ezihlukene. I-Directory[] ibika indawo yesihlaziyeleli, futhi yilowo mzila obalulekile ku-Import, Export namagama efayela ahlobene. Isethi yedatha eduze kwencwadi yamanothi ku-laptop ayibonakali ku-kernel egijima kwenye imishini.

Nquma ukuthi idatha izofinyelela kanjani kuseva ngaphambi kokubhala ukuhlaziya: indawo efakwe ngokwabiwe, isinyathelo sokudlulisa esigunyaziwe, noma isizindalwazi iseva engasifinyelela ngqo. Lokhu kukhetha kuthinta ukuphindaphinda, ngoba incwadi yamanothi encike emzileni we-laptop izohluleka ngokuzayo lapho omunye umuntu eyisebenzisa.

Qalisa i-kernel ngesiteshi esigunyaziwe

Umhlahlandlela wama-kernel akude we-Wolfram uchaza ukwengeza ukufakwa kwe-kernel, ukukhetha imishini ekude nokuqalisa nge-SSH. Umzila wefayela elisebenzayo nezimpikiswano esibonelweni kungokohambo lomsebenzi womkhiqizo lowo; zivumelanisa nomsingathi nenguqulo okushiwo ngumlawuli esikhundleni sokuzinamathisela zingashintshiwe.

Ubunikazi bomsingathi buyingxenye yokulungiselela. Qinisekisa ukhiye womsingathi we-SSH ngohlelo lwenhlangano, sebenzisa indlela yokuqinisekisa ekhishiwe, futhi gcina okhiye abayimfihlo namagama ayimfihlo ngaphandle kwamafayela encwadi yamanothi abiwayo noma afakwa endaweni yokugcina. Incwadi yamanothi enomyalo wokuqalisa nomagama ayimfihlo ukuvuza kwemininingwane yokungena, hhayi ukunethezeka.

Ungavuli isilaleli se-WSTP ku-inthanethi njengendlela emfushane. Iphethini esekwayo ukuqalisa nge-SSH, egcina isiteshi se-kernel ngaphakathi kokuxhumana okuqinisekisiwe. Uma ithimba lenethiwekhi ligunyaze enye indlela yokudlulisa, sebenzisa leyo, kepha thatha imbobo yesihlaziyeleli evulekile njengoshintsho lwedizayini, hhayi isinyathelo sokuxazulula izinkinga.

Qala ngokuhlola ilungelo, idatha nosayizi wokuphuma

Qinisekisa nomnikazi welayisense ukuthi iseva ingaqalisa i-kernel yalo msebenzisi nokuthi izikhathi eziningi kanyekanye zivunyelwe. Ukubala okukude kuvame ukunikezwa ilayisense ngokuhlukile kungaphambili kwedeskithophu, futhi ukuqalisa okwehlulekile ngenxa yelungelo kubonakala njengomyalo we-SSH ohlulekile kuze kube umuntu ufunda umyalezo weseva.

Bese ulinganisa usayizi womphumela. I-kernel ebuyisela isisho samabhayithi amakhulu ambalwa izothumela ngamashaneli okuqalisa ne-kernel kuya kungaphambili, okungase kumise noma kuqede imemori ye-laptop. Gcina ukuhlanganiswa okusindayo kuseva bese ubuyisela izifinyezo, noma bhala imiphumela emikhulu emzileni kuseva bese uyidlulisa ngamabomu.

Bhala umzila wefayela elisebenzayo, izimpikiswano zokuqalisa nendawo yokusebenza kumanothi okulungiselela encwadi yamanothi. Umsebenzisi olandelayo uzophinda enze leli hlelo esikhundleni sokuphinda athole ukuthi imuphi kulezi zindlela ezinhlanu ezingaba khona esetshenziswa yiseva.

Hlola izigaba ngokulandelana

Izigaba ezinhlanu kufanele ziphumelele, futhi ngasinye sinokuhlolwa kwakho okuhlukile. Qala ku-laptop bese uma ehlulekeni lokuqala esikhundleni sokushintsha izilungiselelo eziningi ngasikhathi sinye:

nc -vz research.example.edu 22
ssh -v [email protected] 'hostname; command -v wolframscript'
ssh [email protected] 'wolframscript -code "$MachineName"'

Ukuhlolwa kwe-TCP okwehlulekile kukhombisa umzila, i-DNS noma izindawo ezivunyelwe ze-VPN. Ukuhlolwa kwe-TCP okuphumelele nokungena kwe-SSH okwehlulekile kukhombisa ukuqinisekisa noma inqubomgomo yokhiye womsingathi. Ukungena okusebenzayo kepha okungatholi ifayela elisebenzayo kukhombisa ukufakwa kwe-kernel noma umzila onikezwe ingaphambili. I-kernel eqala kepha engaxhumani neze ikhombisa izimpikiswano zokuqalisa noma udonga lomlilo lwendawo.

Gcina iphutha lokuqala elinengqondo bese uthumela izigaba zohlangothi lweseva kumlawuli ongumnikazi wale mishini. Ukuphinda kwakhiwe ukufakwa kwe-kernel kufihla ukuthi yisiphi isigaba esihluleke ngempela, futhi kulahla ubufakazi umlawuli abudingayo.

Ekugcineni ufuna iwindi olimaziyo, isihlaziyeleli ongasibiza ngegama nomzila okuvunyelwene ngawo wekhodi namafayela. I-VPN iyingxenye eyodwa yalowo mzila, futhi lapho ukuhamba komsebenzi kukubonisa kusenesikhathi, isikhathi esincane sichithwa ekuxhumeni kabusha umhubhe ongakaze ube yinkinga.
