Hlola ukuthi i-proxy yakho ayivulekele wonke umuntu
Ngaphambi kokuvula i-forward proxy, hlola umlaleli, ukuhleleka kwemithetho, imininingwane yokungena nokudluliswa kwangempela okuvela emithonjeni evunyelwe neyenqatshiwe.
Hlola umngcele wokufinyelela ngaphambi kokwenza i-forward proxy entsha ifinyeleleke kwamanye amanethiwekhi. Isicelo esiphumelelayo esivela kuseva uqobo sifakazela okuncane ngalokho iklayenti langaphandle elingakwenza. Sebenzisa indawo oyilawulayo ukuze wazi ukuthi isicelo esenqatshiwe sadluliswa ngempela yini.
Hlola umlaleli nenqubomgomo esebenzayo
Bheka inqubo elalelayo namakheli, ne-IPv6 uma ivuliwe. Susa abalaleli abengeziwe abangahlosiwe noma izimo zesevisi ezindala. Gcina i-firewall yenethiwekhi ivumela imithombo okufanele ifinyelele isevisi kuphela.
Bese uhlola izilungiselelo ezilayishwe ngempela, namafayela afakiwe. Ku-Squid 6 imvume yangaphambili ingenza umkhawulo olandelayo ungasebenzi. Ku-Tinyproxy 1.11.2 ukususa yonke imigqa ye-Allow ne-Deny kuvumela wonke amaklayenti. I-Dante ine-mithetho yeklayenti ne-SOCKS ehlukene, ngakho ukwamukela uxhumano lwe-TCP akuyona yonke inqubomgomo.
Sebenzisa idokhumenti yenguqulo efakiwe. Izinguquko zeziqondiso ze-Squid 8 ziyisizathu sokuhlola inguqulo, hhayi sokucabanga ukuthi izilungiselelo ezijwayelekile zamukelwe ngencazelo efanayo.
Hlola kokubili okuvunyelwe nokwenqatshiwe
Uma i-proxy ihloselwe ukudinga kokubili umthombo ovunyelwe nokungena, hlola leli thebula ngezinhlelo ozilawulayo:
| Umthombo | Imininingwane yokungena | Umphumela odingekayo |
|---|---|---|
| Uvunyelwe | Ilungile | Indawo ehlosiwe ithola isicelo. |
| Uvunyelwe | Ayikho noma ayilungile | Isicelo asifinyeleli endaweni. |
| Awuvunyelwe | Ilungile noma ayikho | Isicelo asifinyeleli endaweni. |
Amadivayisi amabili ngemuva kwe-NAT eyodwa angabonakala ewumthombo owodwa. Khetha izindawo zokuhlola ezinamakheli omthombo ahlukene ku-proxy, uqinisekise kulogi. Ungasebenzisi imishini yabantu besithathu abangahlobene noma uskene izinsizakalo zabanye.
Ukwenqaba kwe-firewall kungase kungakhiphi nhlobo impendulo ye-HTTP; ukwenqaba kohlelo kungabuyisa iphutha. Kokubili, hlola ukuthi indawo oyilawulayo ayitholanga isicelo esinqatshelwe; ikhasi lephutha kuphela lingadidaniswa nempendulo yendawo.
Hlola izindlela zokudlulisa ohlose ukuzivumela
Ku-web proxy, hlola i-HTTP evamile nendlela ye-HTTPS CONNECT evunyelwe ngokwehlukana. Uma imikhawulo yezindawo iyingxenye yenqubomgomo, hlola indawo evunyelwe nenye oyilawulayo okufanele yenqatshwe. Ungasusi izilawuli ukuze nje konke ukuhlola kuphumelele.
Hlola futhi ngemva kokushintsha ububanzi bemithombo, imininingwane yokungena, amakheli abalaleli, amafayela afakiwe noma izinguqulo zesevisi. Gcina isikhathi sokuhlola, inguqulo yezilungiselelo nemiphumela ndawonye ukuze ushintsho olulandelayo luhlolwe emngceleni ofanayo.
Lena inqubo yokwamukela, hhayi isitatimende sokuthi i-parser yezilungiselelo noma isicelo esisodwa kungafakazela ukuthi yonke imizila yenethiwekhi ivaliwe.
