Squid ako anonymny proxy server
O užitočností ananoymných proxy serverov asi ani netreba hovoriť.
Squid je pre tento účel priam dokonalý a inštlacia a konfigurácia je jednoducha.
Postup tvorby anonymného proxy
- Inštalácia Squid-u
- Konfigurácia
- Nastavenie ACL
- Nastavenie klienta(IE, firefox)
Nezabudnite nastavit ACL, nechcete predsa aby vam cez Váš anonymný proxy niekdo surfoval nejake nelegálne weby. |
Inštalácia Squid-u
Záleži od distribúcie.
RedHat like
yum install squid
Konfigurácia
Nasledujúci config by mal plne postačiť pre spustenie anonymného proxy. Verzia Squid je Squid Cache: Version 3.0.STABLE10

Nastavenie ACL
Nastavenie ACL je naozaj veľmi dvoležité. V prechadzajúcom kroku su už zahrnuté, teraz si ixh trochu vysvetlíme.
Takto si nastavime IP,ktoré chceme povoliť
acl all src all acl ofice src 208.77.188.166/32 acl home src 208.77.188.167/32 acl mybuddy src 208.77.188.168/32
A týmto ich povolíme
http_access allow mm http_access allow office http_access allow kenny http_access deny all http_reply_access allow mm http_reply_access allow office http_reply_access allow kenny http_reply_access deny all
Nastavenie klienta(IE, firefox)
Nezabudnite, že Squid počúva na porte 3128.
IE
