Networking :: Regarding Squid Server Configuration
Jun 11, 2011
I have 10 systems on my network and I have centos5.5 installed on server. All other clients are on WinXP. I am using squid server to share internet on my network.Problem is: whenever an user trying to open a website through squid server, it opens too slow, but if same user tries to open same website by passing squid server, it opens 3 times faster. Downloading speed is same in both scenario. Only buffering speed is slow through squid.

We have two offices suppose A and B. At office A, we use centos 5.3 computer as router and squid proxy server. At office B we use a cisco router to connect to Internet. Computers at office A that has direct access to Internet can access computers behind cisco router at office B using vnc viewer. But computers at office A that can use internet only through squid proxy can't access computers behind cisco router at office B. Is there any way so that I could allow squid clients to access computer behind cisco router at office B using vnc viewer.

how-to configure squid proxy server. I still haven't been able to find a solution. I want to set up squid as a open http proxy server. So people from other networks can connect through the proxy without having to login.Do I have to use iptables to reroute http traffic to squids proxy port? I have forwarded the port in my ISP modem so I know thats working, its the squid config that has flaws or iptables locally.

I'm going to be going off to college in the fall and the internet probably won't be blazing fast like it is at home, so I was wanting to set my desktop up so that it would act as a local cache of the parts of the internet i frequent the most, but I can't find anything like that. All the tutorials I've found are either for sharing the load on a server or for setting up a separate machine as the squid.

I have been working in Linux for the past two years.And working in squid for the past 6 months.The following is my Setup
ETH1 - ISP1 (Active)
ETH2 - LAN (Active)
ETH3 - ISP2 (Inactive)
Using Iptables I forward 80 port through squid (3128).Other ports just get connected in the proxy machine itself since it has IP_FORWARD enabled. All my client machines browsers enabled with "Use proxy 3128". I just want to make all the port to pass through squid server.

I have an Ubuntu Server 10.10 machine running in-between my firewall and the rest of my network that monitors the internet connection and functions as a web cache.
It had been working for about a year, but started having an issue where no one (either from the server itself or from the local network) could connect to a website. Port 80 was the only one affected, which is forwarded via iptables to port 3128 for Squid.
After lots of trial and error, I thought to do a packet capture from the internet-side of the server (which I should've done in the first place!). Turns out the tcp handshake is not completed. The connection is started with a syn packet; the web server (google.com for example) responds with a SYN/ACK, and then nothing else is sent until the squid server tries again with another SYN packet. It repeats several times like that, then gives up and gives a connection timeout error message.
My iptables rules are as follows:
I'm no guru when it comes to iptables, and when I originally setup the server, I knew even less. So if something is wrong or at least could be done better with the rules please tell me. Also, I should note that I'm using bridge-utils to bridge the two ethernet interfaces. Squid is set as an intercepting (transparent) proxy.

I am having problems while testing out squid proxy server. I just can't get it block anything. So, I'm running Debian lenny on my Virtualbox and Squid on it. I'm having windows 7 on virtualbox too and they can ping each other and the webserver on debian (apache2) is working fine. The problem is i can't get squid to block webpages. I have the correct settings on windows proxy settings, but i'm not so sure about squid. I want to block lets say www . xxx. com for example. So I add to the main configuration file:
