Isabelo sasekhaya se-Samba sashabalala ngemuva kokuba i-OpenVPN ishaye i-DNS

I-Samba ilahlekelwa yizabelo zasekhaya ngaleso sikhathi lapho OpenVPN ixhuma khona, futhi umhubhe cishe awusoze ube yimbangela. Ukufakwa kuhle, i-NAS iyasebenza, futhi isixazululi esifakwe umhubhe siphendula imibuzo ngegama elingakaze lisibone. I-Samba ibuza leso sixazululi ekuqaleni kokulandelana kwayo kokusesha, iyakholwa impendulo futhi ixhuma ekhelini okungekho lutho olulalelayo kulo. Ukulungisa isabelo kusho ukulungisa impendulo, hhayi ukufakwa.

Izivivinyo ezinhlanu, ngokulandelana okususa amathuba amaningi esinyathelweni ngasinye.

Ubani ophendula ngegama elifushane

Buza uhlelo lokusebenza, hhayi umphathi wamafayela. resolvectl status iphrinta amaseva e-DNS axhunywe kusixhumanisi ngasinye futhi ibonisa ukuthi yisiphi isixhumanisi esingumzila ozenzakalelayo, futhi umbuzo wegama elifushane ubika iseva ephendulile. Yisebenzise kanye ngegama le-NAS kanye nangegama owaziyo ukuthi likhona esizindeni sehhovisi. Uma izimpendulo zombili zivela kumaseva ahlukene, utholile ukwehlukana.

Hlola ukuthi impendulo ibiyimpendulo engemihle noma ikheli. Impendulo engemihle isho ukuthi i-Samba bekufanele idlulele kwenye indlela, futhi iphutha likwenye indawo. Ikheli lisho ukuthi i-Samba ixhumene nendawo yangempela futhi ayitholanga lutho.

Kungani i-Samba ikholelwa impendulo engalungile

I-Samba ixazulula amagama ngokulandelana okungaguquki okusetshenziswa yi-name resolve order. Ezinsukwini eziningi izinga elizenzakalelayo lihlanganisa i-host, okusho i-DNS, futhi lisebenza ngaphambi kwezindlela ze-LAN kuphela njengokusakaza kwe-NetBIOS. Ngakho-ke umhubhe oshaya isixazululi uthola ilungelo lokunqaba kokuqala egameni ngalinye lesabelo, kuhlanganise namagama anelebula elilodwa okwakungafanele ashiye isakhiwo.

Ngokuvamile igama elingaziwa libuyisela impendulo engemihle futhi indlela elandelayo ithola ithuba. Ezinye izixazululi, ikakhulukazi eze-ISP zabathengi nezasemphakathini, ziphendula amagama angaziwa ngekhasi lokusesha noma ngekheli lokukhangisa esikhundleni salokho. Leyo mpendulo ibonakala iyimpumelelo emtatsheni wezincwadi wesixazululi, ngakho i-Samba iyeka ukusesha futhi ishaya ikheli elingenakho ukuxhumana nenethiwekhi yakho.

Umphumela isabelo esinyamalalayo ngaphandle kwebhokisi lephutha. Akukho lutho kulokho kulandelana okuwukwehluleka kokuhamba kwe-VPN, yingakho ukupinga i-NAS kusasebenza kuyilapho ukuphequlula kuyo kungasebenzi.

Izilungiso ezimbili ezinobubanzi obuhlukene

Isilungiso esincane sigcina isixazululi esishayiwe futhi sishintsha ukuthi i-Samba ingasibuza ini. Engeza imigqa emibili kukho ukuhlelwa kwe-Samba okufundwa yi-daemon ngempela, bese uqala kabusha insizakalo:

[global]
   name resolve order = wins lmhosts bcast
   dns proxy = no

Uma kungekho host kulolo hlu, i-DNS iphuma endleleni yokusesha izabelo, futhi amagama anelebula elilodwa ahlala esigabeni sasekhaya. Amagama ehhovisi asaxazululwa ngokujwayelekile kuhlelo ngalunye olunye, ngoba lokhu kushintsha i-Samba kuphela. Izindleko yikuthi i-Samba ayisakwazi ukusebenzisa i-DNS nhlobo, ngakho isabelo esikhethwe ngegama lehhovisi eligcwele liba inkinga.

Isilungiso esibanzi sisusa imbangela: yeka ukushaya isixazululi esiphendula amagama okungewona ayo, noma shaya inqubomgomo ye-DNS ehlukanisiwe ukuze izijobelelo zehhovisi kuphela zifinyelele isixazululi sehhovisi. Leyo yimpendulo engcono yesikhathi eside kunethiwekhi ephethwe ngoba ivikela nesiphequluli kanye nomphathi wamaphakheji, kodwa idinga ukufinyelela kokuphatha ohlangothini lweseva kanye nekhasimende elilalela izilungiselelo ezishayiwe.

Khetha okukodwa ngamabomu. Ukushintsha kwesixazululi kushintsha ukuxazululwa kwamagama kuhlelo ngalunye ngesikhathi esisodwa, okuwurekhodi loshintsho, hhayi ukuhlela okokocingo losizo.

Isijobelelo singachaza konke

Uma ikhasimende lishaya nesijobelelo sosesho, igama lasekhaya elifushane libhalwa kabusha esizindeni sehhovisi ngaphambi kokuba libuzwe. Khona-ke isixazululi asiqambi mhlawumbe neze: sabuzwa umbuzo onobulungiswa ngegama lehhovisi futhi sanikeza impendulo efanele. Funda igama elibuziwe kokuphuma kwesixazululi ukuze uhlukanise lokhu necala lekheli lokukhangisa, ngoba amaphutha womabili abonakala efana kumphathi wamafayela.

Isixazululo lapha ukusebenzisa igama lasekhaya eligcwele noma ukwengeza umthetho we-DNS ohlukanisiwe ongumnikazi wesijobelelo sasekhaya. Akukho kukho okubili okudinga ukuthinta i-Samba.

Kufakazela lokho ngemva kokuxhuma kabusha

Vivinya amagama amathathu kuseshini eyodwa: isabelo sasekhaya ngegama elifushane, umsingathi wehhovisi ngegama, kanye newebhusayithi evamile. Uma elokuqala lisebenza futhi elesibili liphuka, isilungiso sasusa iphutha lasihambisa. Uma elesithathu liphuka, ushintsho lwesixazululi lwaqhubeka ngaphezu kwalokho okwakuhloswe futhi konke ukusesha manje kuyasoleka.

Bese unqamula futhi uxhume kabusha umhubhe futhi uphinde konke kuthathu. Izinketho ezishayiwe zisetshenziswa kabusha kukho konke ukuxhumana, ngakho isilungiso esasikhona ngesikhathi sokusebenza kuphela singanyamalala ngaphandle kokuthi ifayela lokuhlela lishintshe. Rekhoda isixazululi esingumnikazi wesijobelelo ngasinye kanye nokulandelana kokusesha okusebenzayo, futhi bhala usuku, ngoba ukubuyekezwa kwekhasimende okulandelayo yisoliswa esisobala lapho lokhu kubuya.

Uma isabelo sisahluleka ngemva kwezivivinyo zontathu ezinhlanu, thwebula umbuzo oqondile nempendulo eqondile ngaphambi kokushintsha enye into. Labo migqa emibili yehlukanisa iphutha lesixazululi negama elingekho ngempela, futhi iyona nothi yokudlulisa eshesha kakhulu ongayibhala.
