squid testiranjeznaci imam dvi virtualne mašine
1. virtualna je server(gateway,proxy) eth0=192.168.1.2 - izlaz na net eth1=192.168.2.1 - lan
2.virtualna mašina je klijent eth0=192.168.2.2 spojena na eth1 na server
operativni sustavi su debian...ispod je konfiguracija squid.conf
Code:
debug_options ALL,1
acl all src 0.0.0.0/0.0.0.0
acl mynet src 192.168.2.0/255.255.255.0
http_access deny all
http_access allow mynet
cache_effective_user squid squid
cache_access_log /usr/local/squid/logs/access.log
cache_log /usr/local/squid/logs/cache.log
cache_dir ufs /usr/local/squid/cache0 500 16 256
cache_dir ufs /usr/local/squid/cache1 500 16 256
cache_mem 80 MB
cache_mgr root@localhost
http_port 3130
debug_options ALL,1
acl all src 0.0.0.0/0.0.0.0
acl mynet src 192.168.2.0/255.255.255.0

http_access allow mynet

cache_dir ufs /usr/local/squid/cache1 500 16 256
cache_mem 80 MB
cache_mgr root@localhost
http_port 3130
nakon editiranja squid.conf unesene su slijedece komande
Code:
/usr/local/squid/bin/squid -z
/usr/local/squid/bin/squid -Ns &
/usr/local/squid/bin/squid -z
/usr/local/squid/bin/squid -Ns &
također sam kreirao usera squid,dao mu potrebne ovlasti,kreirao keš direktorije, i sl
zatim sam unio iptables kod da napravi od računala gateway i da sve na portu 80 redirekta na squid default port
Code:
SQUID_SERVER="192.168.1.2"
INTERNET="eth0"
LAN_IN="eth1"
SQUID_PORT="3130"
iptables -F
iptables -X
iptables -t nat -F
iptables -t nat -X
iptables -t mangle -F
iptables -t mangle -X
modprobe ip_conntrack
modprobe ip_conntrack_ftp
echo 1 > /proc/sys/net/ipv4/ip_forward
