squid proxy

[sathish]

Hello Linux Team,


My distro is redha 9, done masquerading and running squid my network setup is as follows :-

LINUX BOX - MASQUERADE+FIREWALL+SQUID
|
|
V
WIN2K SERVER [ Done Internet Sharing ]
|
|
V
connected to L A N - 50 Client

Now my question is instead of going to each 50 individual client and configuring proxy settings, is it possible to do it in LINUX BOX, so that proxy setting should take automatically.

Plz let me know .

Thank you.

I don't understand that whay you have done following..

LINUX (with masq+proxy+firewall) ------> Win2K (ICS) ---> CLIENTS

IF you can already do ICS with LINUX machine .. that is what masquerade is for then whay you have used win2k machine for sharing ? ie for NAT ?

Now my question is instead of going to each 50 individual client and configuring proxy settings, is it possible to do it in LINUX BOX, so that proxy setting should take automatically.

That is where the Trasnparent Proxy comes. It is simple NAT + port redirection to proxy port!

Hi Ricky,

yes, u have catched my point,

yes linux box will share the net to WIN2K SERVER and then win2k server to the clients.

now i have done Transparent proxy also, like this

iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3128.

1) but in squid, i have allowed some url to access and remaining all sites is banned, this is not working even transparent proxy is active, when I browse sites it is accessing all sites, wat to do for this ??
when i go to each system and configure proxy setting in internet explorer like this [ proxy server 10.10.1.1 port 3128 ]. it will work, i mean the banned list and the access list.


2) we are having a Online Software, I want to configure this software not to authenticate to squid, it should directly connect to the internet. how to do ??

Thanking you,

Sathish.
