I-VPN runtime ku-RAM ayisho lutho ngamalogi

Iseva ye-VPN eqala kusuka kusithombe sokufunda kuphela futhi igcina isimo sayo sokusebenza ku-tmpfs iwumklamo wangempela futhi owusizo. Kulula futhi ukuyichaza njengengenamalogi, lokho umklamo ongakufakaziyo. Indawo yokugcina inquma ukuthi ikhophi ihlala kuphi; ukuqoqwa nokugcinwa kunquma ukuthi ingabe irekhodi likhona nhlobo, futhi ukuqala kabusha kuthinta okokuqala kuphela. Ukuhlukanisa lezi ezimbili yiwo wonke ukubuyekezwa.

Qala ngokubala zonke izinqubo ezingabhalayo isimo: i-daemon, insiza yokuqinisekisa, ijenali, noma iyiphi i-ejenti yokuqapha kanye namathuluzi okuphatha.

Ukugcina nokuqoqa kuyimibuzo ehlukene

Umbhali ngamunye unendawo yakhe kanye nenqubomgomo yakhe. I-daemon ye-VPN ibhala amafayela esimo, ingemuva lokuqinisekisa libhala izehlakalo ze-akhawunti, ijenali iqoqa umphumela wezinsiza, futhi i-ejenti yokuqapha ithumela izilinganiso kwenye indawo ngokuphelele. Umklamo owenza okunye kwalokhu kunyamalale ekuqaleni kabusha awusho lutho ngezinye ezintathu. Landela umbhali ngamunye endaweni yakhe bese uphawula ukuthi ingabe leyo ndawo isemishinini nhlobo.

Amafayela aqondene nohlelo lokusebenza, izixilongo ezilayishiwe kanye nezinsiza zangaphandle zidinga ukuphathwa okufanayo. Ukungabikho kwelogi yendawo eyaziwayo akufakazi ukuthi amarekhodi okuxhumana noma e-akhawunti awekho ndawo; kufakaza ukuthi awukayitholi indawo eziya kuyo.

I-tmpfs ayisiqinisekiso

I-Linux tmpfs ayilona idiski le-RAM lomzimba. Imibhalo ye-kernel icacile ukuthi amakhasi angabhalwa ku-swap uma ukufaka kuvuma, ngakho ifayela le-tmpfs lingafinyelela idiski ngaphandle kokuthi uhlelo lokusebenza lulikopishe lapho. mount ikhombisa ukuthi ingabe i-tmpfs esekelwe yi-swap iyasebenza, futhi ezinye izinhlelo zamafayela zememori ziziphatha ngendlela ehlukile futhi. Funda izinketho zokufaka zangempela esikhundleni sokucabanga ukuthi indlela engaphansi kwe-/run isho ukungazinzi.

Bese wenza uhlu lwezinto ezisinda ukuqala kabusha ngezindlela abantu abazikhohlwayo: ungqimba oluphezulu oluhlala njalo, isitoreji esixhunyiwe, izithombe zokulala, amadampasi okuphahlazeka kanye nezithombe zengqalasizinda ye-VM yonke. Ngayinye iyindawo engaba khona yesimo obucabanga ukuthi siyesikhashana. Lolo hlu luyinto okufanele ihlolwe, hhayi isimangalo sokuthi wonke umphathi unakho konke.

I-Journald inezindawo ezimbili kanye nesidlulisi

I-Journald ikhombisa ukwehlukana ngobuciko. Isitoreji esiguqukayo sigcina okufakiwe ngaphansi kwe-/run/log/journal, esihlala njalo ngaphansi kwe-/var/log/journal, futhi imodi ezenzakalelayo ikhetha phakathi kwazo; imodi esebenzayo ivela kusistimu esebenzayo hhayi encazelweni yesithombe. Ukushintshela kokuguqukayo akususi lokho osekuvele kwabhalwa unomphela. Ukudlulisa nakho kuyisiteshi esihlukile: ngisho isilungiselelo sesitoreji esingagcini lutho endaweni singadlulisela imiyalezo kwenye indawo.

Funda imodi esebenzayo kuyo ijenali ngokwayo noma kufayela layo lokucwangcisa, bese uhlola izindawo zokudlulisa ngokwahlukile, ngoba isilungiselelo esisodwa asilawuli esinye.

Yini okufanele isinde ukuqala kabusha

I-runtime engenasimo isekela ukushintshwa okuphindwayo, futhi idinga imithombo ehlosiwe yokucwangcisa, ukugunyaza kanye nempahla yokubuyisela insiza engakwazi ukuyiqamba. Ukulahlekelwa isimo sokuqala sokubhalisa noma sokuhoxisa esisebenza ukuze kubhalwe endaweni kunyamalale kuwukuhweba okubi, futhi kuvamile. Nquma ukuthi yini okufanele isinde ngamabomu, bese uqinisekisa ukuthi iyasinda.

Ukucabanga okufanayo kusebenza kumarekhodi okusebenza. Nquma ukuthi yiziphi izehlakalo ezidingwa ngempela ukuphepha nokuphathwa kwezinsiza, ngobubanzi nokugcinwa okufanele, bese unciphisa okusele. Ukunciphisa akufani nokucisha zonke izixilongo.

Qhathanisa ukucwangciswa kwesitoreji nokudlulisa okusebenzayo nezehlakalo ezimbalwa ezingenangozi, bese uqala kabusha noma ushintshe umshini futhi uhlole futhi ukuthi kwasele ini nokuthi insiza yabuyisa kuphi isimo sayo.
