Kungani i-Squid inesokhethi ye-UDP embobeni engalindelekile
Hlukanisa amasokhethi e-UDP e-DNS ne-peer-cache e-Squid kusilaleli se-TCP esisetshenziswa ngamaklayenti njenge-proxy yokuqhubekela phambili.
Imbobo ye-UDP engaziwa ephethwe yi-Squid ayiyona ngokuzenzakalela enye i-HTTP proxy yomphakathi. Amaklayenti asebenzisa isilaleli se-TCP esilungiselwe ukufinyelela okujwayelekile kwe-HTTP proxy; i-Squid ibuye ivule amasokhethi e-DNS kanye nokuxhumana nozakwethu we-cache.
Ukuze ukhombe isokhethi elengeziwe, bhala:
- Ukuthi yi-TCP noma i-UDP, ikheli elibophelelwe kanye nanoma iyiphi indawo yokugcina ekude ekhonjisiwe.
- Izilungiselelo ezisebenzayo zesilaleli, i-DNS, i-ICP ne-HTTP yesikhathi esithile.
- Ukufinyeleleka kwenethiwekhi okudingwa yisici esivulwa yilezi zilungiselelo.
Isiqondiso sekheli le-UDP se-Squid sihlanganisa ngokusobala amamojula e-DNS, i-ICP ne-HTTP. Ukuziphatha kwazo akukwazi ukucatshangwa kusuka ku-http_port, futhi inombolo yembobo ephezulu iyodwa ayikhombi isici.
Ungafaki leyo ndawo yokugcina ye-UDP emkhakheni we-HTTP proxy wohlelo lokusebenza noma ukuvulela wonke amaklayenti ngenxa nje yokuthi ivela ohlwini lwamasokhethi. Ngakolunye uhlangothi, ukuvimba indlela ye-DNS esetshenziswa yi-Squid ngempela kungaphula ukuxazululwa kwendawo okuya kuyo kamuva. Shintsha umthetho we-firewall womsebenzi okhonjiwe: isokhethi yombuzo wesixazululi, imbobo yozakwethu we-cache nesilaleli samaklayenti kunemisebenzi ehlukene.
