Izibuyekezo zeseva ye-VPN ezingagadiwe zidinga indlela yokululama ehloliwe
Isibuyekezo singaqala kabusha insiza oyisebenzisayo ukufinyelela iseva. Qhathanisa ikhonsoli engaphandle kwebhendi necebo lokululama elisebenzisa umhubhe kuphela ngaphambi kokwenza okuzenzakalelayo.
Izibuyekezo ezingagadiwe ziyinqubomgomo enengqondo yeseva oyifinyelela nge-VPN yayo, futhi ngesikhathi esifanayo ziyindawo eyodwa yokwehluleka oyizakhelayo. Umsebenzi wephakethe uqala kabusha insiza, umhubhe uyawa, futhi indlela yokuphatha obuyisebenzisa iyanyamalala kanye nawo. Kunezindlela ezimbili zokululama, futhi ukukhetha phakathi kwazo kuncike esimweni esisodwa: ukuthi unayo yini indlela yokungena engadluli entweni ebuyekezwayo.
Izindlela ezimbili zokululama, isimo esisodwa esinqumayo
Indlela yokuqala ithemba isibuyekezo futhi icabanga ukuthi uzokwazi ukuxhuma futhi ngemva kwaso. Iyasebenza lapho i-VPN ingenye yezindlela ezimbalwa zokufinyelela umphathi futhi lapho ukwehluleka komhubhe kungakususi ikhono lakho lokuxilonga. Indlela yesibili ibeka kusengaphambili indlela ezimele, ngokuvamile ikhonsoli yomhlinzeki wokubamba, futhi ithatha umhubhe njengento okungenzeka kakhulu ukuthi isilungiso siyiphule. Zombili izindlela ziyavikeleka, futhi eyodwa kuphela yazo idinga umsebenzi kusengaphambili.
Isimo esinqumayo kulula ukusisho futhi kulula ukusidlula. Uma zonke izindlela zokuphatha eziya emshinini zidlula ensizeni ebuyekezwayo, awunayo indlela yokululama nhlobo, unombono nje. Kusitshele ngokuzwakalayo ekubuyekezweni koshintsho.
Ukuhlola leso simo kuthatha imizuzu eyishumi futhi kufanele kwenzeke ngaphambi kwesibuyekezo sokuqala esingagadiwe, hhayi ngesikhathi sezehlakalo. Vula ikhonsoli ngenkathi konke kusebenza, qinisekisa ukuthi izifakazelo zisebenza, bese uyivala futhi. Qinisekisa ukuthi ikhonsoli ivuleka kumphathi ocabanga ukuthi unjalo. Bese uqinisekisa ukuthi ukungena ozokwenza ngempela ngo-3 ebusuku kusasebenza.
Le ngxenye yokugcina ibaluleke kakhulu kunalokho ezwakala. I-akhawunti yekhonsoli igama lokugxila elishintshwe izinyanga eziyisithupha ezedlule futhi elingakaze liqinisekiswe ayiyona indlela yokululama; idokhumenti nje echaza enjalo.
Okungakubuyiseli ikhophi yokugcina
Ingobo yokucushwa ingumbhalo wamafayela, futhi isibuyekezo sishintsha okungaphezu kwamafayela. Isimo sephakethe, amamojula ekhineli, izixhumanisi zamayunithi ezinikwe amandla kanye nemithetho yodonga lomlilo esetshenziswe ngethuluzi elihlukile konke kuhlala ngaphandle kwedlanzana lokucushwa, futhi ukubuyisela okungakunaki kukhiqiza umshini obonakala ucushwe kodwa ongadlulisi.
| What changed | Restored by a configuration backup | Needs its own action |
|---|---|---|
| Service unit or startup ordering | Partly, if the unit file was included | Package state and enabled links |
| Kernel module or interface support | No | Kernel or module rollback, or a boot-time decision |
| Peer or device authorization | Only if the backup predates the revocation | A deliberate decision about which peers return |
| Firewall rules applied outside the config | Only if they were captured | Replaying and verifying each rule |
Ukwagunyaza kufanele ukuthola umugqa waso. Ikhophi ethathwe ngaphambi kokuba idivayisi ehlaselekile isuswe izobuyisela ngokukhululeka ukufinyelela kwaleyo divayisi. Ukubuyela kuyo ngesikhathi sokuphazamiseka yiyo indlela okwenza isehlakalo esisodwa sibe ezimbili, futhi isinqumo sokubuyisela kufanele sithathwe ngabalingani ngokucacile njengoba sithathwa ngamafayela.
Indlela yokuhlehla nayo ibalulekile. Ukukopisha ifayela lokusebenza elidala phezu kwalelo elilawulwa iphakethe akulona ukuhlehlisa okusekelwayo koshintsho lwephakethe, futhi kushiya isizindalwazi samaphakethe sichaza isimo isistimu yamafayela engavumelani naso. Sebenzisa indlela yokwehlisa inguqulo yomphathi wamaphakethe uqobo noma isithombe esisheshayo esinikezwa umhlinzeki. Ukwehlisa inguqulo okubhalwa isizindalwazi samaphakethe yikho ongakwazi ukuphinda ukwenze.
Akukho kulokhu okuphikisana namakhophi okugcina. Kukhulumela ukwazi ukuthi iyiphi ingqimba ehlanganiswa yiliphi into, ngoba indlela yokwehluleka kokubuyisela ingxenye iyadida ukwedlula ukuphazamiseka kwasekuqaleni. Bhala ingqimba eceleni kwekhophi ngayinye ku-runbook.
Iphuzu lokuhlola, isibuyekezo, bese kuqinisekiswa kusuka ngaphandle
Rekhoda isimo ngaphambi koshintsho ngendlela ozokwazi ukuyiqhathanisa kamuva: izinguqulo ezifakiwe, amayunithi ensiza athintekayo, amasokhethi alalelayo kanye nohlu lwabalingani lwamanje. Imiyalo emine ihlanganisa iningi lalokhu kumphathi we-Linux.
systemctl list-units --type=service | grep -E 'openvpn|wg-quick'
ss -lunp | grep -E ':51820|:1194'
journalctl -u wg-quick@wg0 --since '-10 min'Eyokuqala ikhombisa ukuthi yimaphi amayunithi akhona nokuthi ayasebenza yini, eyesibili iqinisekisa ukuthi umlaleli uboshiwe ngempela, futhi eyesithathu ikunikeza incazelo yensiza uqobo mayelana namaminithi adlule. Akukho kuzo okuqinisekisa ukuthi iklayenti lingaxhuma, yingakho isinyathelo esilandelayo senzeka ngaphandle komphathi. Gcina lokho kufunda njengesisekelo sakho sokuqhathanisa.
Qinisekisa kusuka kunethiwekhi engawusebenzisi umhubhe: qinisekisa iklayenti elilodwa eligunyaziwe, xazulula igama, futhi ufinyelele uhlelo olulodwa oluhlosiwe. Umugqa wesimo sendawo othi isixhumi siphakeme uyisitatimende ngesixhumi, hhayi ngokuhamba kwendlela, izikhiye noma inqubomgomo evumela umlingani.
Bese uhlola indlela yokuxhuma futhi ngamabomu. Qala kabusha insiza kanye futhi uqinisekise ukuthi umhubhe ubuya ngaphandle kokungenelela kwesandla, ngoba insiza eqala kahle kuphela ngesikhathi sokuqalisa iyinsiza ezokumangaza ngesikhathi esibi kakhulu.
Uma yehluleka, sebenzisa indlela oyihlolile
Ukulandelana kokululama akukhazimuli futhi kuyasebenza: finyelela kumphathi ngendlela ezimele, funda amalogi ensiza uqobo, futhi ubuyisele iphuzu lokuhlola elithile elihambisana nokwehluleka. Shintsha into eyodwa esivivinyweni ngasinye ukuze ukufundwa kwelogi okulandelayo kube nencazelo.
Melana nesifiso sokwenza izinguquko ezimbalwa ezingarekhodiwe ukuze ukuxhumana kubuya. Umshini olungiswe ngezinguquko ezinhlanu ngesikhathi esisodwa awukwazi ukuchazwa ngemva kwalokho, futhi isibuyekezo esilandelayo sizoletha futhi leyo eyayithwala umthwalo ngempela.
Bese unquma inqubomgomo ehlala njalo ngobufakazi. Uma isibuyekezo siveza ukuncika okungabhalwanga muntu, ukulungiswa ingumbhalo kanye nokuhlola, hhayi ukucisha izibuyekezo. Uma siveza insiza engakwazi ukuqala kabusha ngokuhlanzekile, ukulungiswa kuseyunithi, hhayi kushejuli.
Ukuqhathanisa kuxazululeka ngokuhlanzekile uma isimo sesinikezwe igama. Indlela ezimele yenza izibuyekezo ezingagadiwe zibe yingozi elawulekayo. Ukungabikho kwayo kwenza inqubomgomo efanayo ibe ukuphazamiseka okuhleliwe okunesikhathi sokululama esingaziwa, futhi asikho isilinganiso sokuzenzakalela esishintsha leyo zibalo.
