Me yasa Squid ke da soket UDP a tashar da ba a zata ba
Bambance soket ɗin UDP na DNS da peer-cache na Squid daga mai sauraron TCP da abokan ciniki ke amfani da shi a matsayin wakili na gaba.
Tashar UDP da ba a sani ba mallakar Squid ba ta zama wani wakilin HTTP na jama'a kai tsaye ba. Abokan ciniki suna amfani da mai sauraron TCP da aka saita don shiga wakilin HTTP na yau da kullum; Squid kuma yana buɗe soket don DNS da sadarwa da takwarar ajiya.
Don gano ƙarin soket, rubuta:
- Ko TCP ne ko UDP, adireshin da aka ɗaure shi da kowane ƙarshen nesa da aka nuna.
- Saitunan mai sauraro, DNS, ICP da HTCP masu aiki na wannan misalin.
- Isarwar cibiyar sadarwa da fasalin da waɗannan saitunan ke kunna ke buƙata.
Bayanin adireshin UDP na Squid ya ƙunshi modules DNS, ICP da HTCP a fili. Ba za a iya gane halinsu daga http_port ba, kuma babban lambar tasha shi kaɗai ba ya gano fasalin.
Kada ka shigar da wannan ƙarshen UDP a filin wakilin HTTP na wani aikace-aikace ko ka buɗe shi ga kowane abokin ciniki kawai saboda ya bayyana a jerin soket. Akasin haka, toshe hanyar DNS da Squid ke amfani da ita a zahiri na iya karya warwarewar manufa daga baya. Canza ƙa'idar wutar bango don aikin da aka gano: soket ɗin tambayar mai warwarewa, tashar takwarar ajiya da mai sauraron abokin ciniki suna da ayyuka daban-daban.
