Iqela lophuhliso Isikhangeli sewebhu esidumileyo sigxile kubucala babasebenzisi kunye nokungaziwa, ikhuphe inguqulelo entsha yeTor 0.4.0.5, Ngomphuculo olutsha olongezwa kwisikhangeli kunye nokulungiswa kwe-bug malunga nohlobo lwayo lwangaphambili.
Kulabo abangaqhelekanga ngesikhangeli sewebhu seT Tor, kuya kufuneka uyazi loo nto Esi sisikhangeli sewebhu esizimeleyo kunye neqonga, isekwe kwiFirefox.
I-Tor isekwe kwinjongo, Yintoni ukwenza inethiwekhi zonxibelelwano apho isazisi kunye nedatha yabasebenzisi ikhuselweyo, engabonakalisi ubunikazi bayo, oko kukuthi, idilesi ye-IP kwaye igcina ingqibelelo kunye nokugcinwa kwemfihlo yolwazi oluhamba ngalo.
Le nguqulo intsha ye I-Tor 0.4.0.5 yamkelwe njengokukhutshwa okokuqala okuzinzileyo yesebe le-0.4.0, esele liphuhlile kwiinyanga ezine ezidlulileyo.
Iimpawu ezintsha eziphambili zeTor 0.4.0.5
Ngolu khululo lutsha lweTor 0.4.0.5 lubalasele ekuphunyezweni kwecala labathengi, yongeze imo yokugcina amandla, apho ukungasebenzi ixesha elide (iiyure ezingama-24 okanye nangaphezulu), umthengi ungena kwimeko yokulala, eyeka umsebenzi wenethiwekhi kwaye engazisebenzisi izixhobo zeCPU.
Ukubuyela kwimowudi yesiqhelo kwenzeka emva kwesicelo esivela kumsebenzisi okanye emva kokufumana umyalelo wolawulo.
Ukulawula ukuqhubeka kwakhona kwimowudi yokulala emva kokuqalisa kwakhona, Kucetyiswa ukuqalwa kokucwangciswa kweDormantOnFirst (ukubuyela kwangoko kwimowudi yokulala, ngaphandle kokulinda iiyure ezingama-24 ezilandelayo zokungasebenzi).
Ezinye izinto ezintsha evelele kolu khululo lutsha kukuphunyezwa kolwazi olunenkcukacha malunga nenkqubo yokuqalisa kweTor (bootstrap), ekuvumela ukuba uvavanye oonobangela bokulibaziseka kokuqalisa ngaphandle kokulinda ukuphela kwenkqubo yonxibelelwano.
Ngaphambili, ulwazi lwaluboniswa kuphela emva kokuba uqhagamshelo lugqityiwe, kodwa inkqubo yokuqalisa eneengxaki ezithile yayixhoma okanye ingaqhuba iiyure, idale imeko yokungaqiniseki.
Ngoku, iingxelo zemicimbi evelayo kunye nenqanaba lokukhululwa ziboniswa njengenkqubela phambili ngokwamanqanaba ahlukeneyo. Ibonisa ulwazi malunga nenqanaba lonxibelelwano ngommeli kunye nokuhanjiswa okuqhagamshelwe ngokwahlukeneyo.
Ukongeza kuyo Inkxaso yokuqala yolungiso lokongezwa kwamaphedi lwenziwa (WTF-PAD-Adaptive Padding) ukulwa neendlela ezingathanga ngqo zokumisela iinyani zokufikelela kwiindawo ezifihliweyo kunye neenkonzo ngokuhlalutya iimpawu zokuhamba kwepakethi kunye nokulibaziseka phakathi kwazo okuhambelana neendawo ezithile kunye neenkonzo.
Ukuphunyezwa kubandakanya oomatshini baseburhulumenteni abasebenza kunikezelo olunokwenzeka lwamanani okupakishwa kokulibaziseka kwepakethi endaweni yezithuthi ezihamba kakuhle. Imowudi entsha ngoku isebenza kwimowudi yovavanyo kuphela. Okwangoku, kuphela kukugcwaliswa kwenqanaba lokudityaniswa.
Kwezinye izinto ezintsha ezivelayo, sifumana:
Uluhlu olucacileyo lweenkqubo zenkqubo yeTor ezibizwa ngexesha lokuqalisa kunye nokucima ukongezwa. Ngaphambili, ezi nkqubo zangaphantsi zazilawulwa kwiindawo ezahlukeneyo kwikhowudi kwaye ukusetyenziswa kwazo kwakungacwangciswanga.
I-API entsha yokulawula iinkqubo zomntwana iphunyeziwe, eyenza indlela yothungelwano lwendlela ezimbini phakathi kweenkqubo zomntwana kwiinkqubo ezinjenge-Unix nakwiWindows.
Yongeze ukhetho UmxhasiAutoIPv6ORPort, ukwenza abathengi ngokungakhethiyo bakhethe i-IPv4 okanye i-IPv6 ORPort node.
Ukukhetha ngokungakhethiyo kusetwa ngalo lonke ixesha xa i-node ilayishwe kwisivumelwano esitsha okanye ukumiselwa kwebhulorho.
Kananjalo, olu khetho kulindeleke ukuba luvumele abathengi ukuba baqale ngokukhawuleza ngaphandle kokumisela ukuba bayayixhasa na i-IPv4, IPv6, okanye zombini.
Ungasifaka njani isiKhangeli seTor kwi-Ubuntu nakwiziphumo?
Kulabo banomdla wokukwazi ukufaka isikhangeli, banokwenza oko ngokulandela imiyalelo esabelana ngayo ngezantsi.
Kuqala kuya kufuneka sivule i-terminal kwaye senze le miyalelo ilandelayo:
wget https://dist.torproject.org/tor-0.4.0.5.tar.gz tar -xvf tor-0.4.0.5.tar.gz
Emva koko sizibeka ngaphakathi kwifolda esiyivulayo kwaye siyenze:
cd tor-0.4.0.5 ./configure make make install
