Server :: Squid Forward_for Appears To Not Work?
Jan 8, 2011
I currently have the set up as shown below: [Internet] - [Gateway Appliance] - [Squid Server] - Client Workstations.
I have configured squid 3.1.6 on Ubuntu 10.10 and have got it working. However, When I add the line:
forwarded_for transparent The HTTP Header should remain unaltered (This is my understanding anyway).
What I want to achieve is that when a Client computer connects via the Squid server, it is routed via the Gateway Appliance and out onto the internet. But using the forwarded_for transparent I want the content filter list, to show the source computer as a client IP address and NOT the IP of the squid server.
Is this possible, if so could someone point me in the right direction onto getting it working.

I am looking for the syntax for a sendmail ruleset to log the message subject to the syslog service. I have found a few posts on the web, but none seem to work. The basic appear to be - add the following to the sendmail.mc file then compile the sendmail.cf file using M4. The syntax suggested follows (I believe the rewrite rule is incorrect)(I and using <T> to indicate tabs):
LOCAL_CONFIC
Klog syslog
HSubject:<T>$>Check_Subject
LOCAL_RULESETS
SCheck_Subject
R$*<T>$:<T>$(log Subject=$1<T>$)<T>$1
sendmail.cf compiles and when used as the config file for sendmail - everything appears to work, but no subject is logged.

I have installed and tried both squid version as transparent proxy but they just don't work.
I have eth0 which is where my internet comes in and eth1 which is my local network 192.168.1.0/255.255.255.0.
My default firewall policy is to drop input output and forward, i have already set my firewall to accept and workout the squid and it is working.
Here is the relevant rules i have on my firewall:
Code:
Here is the sample conf i am using for squid:
Code:
Always_direct allow all When using version 2.7.x i was able to make it transparent when i used the below rules:
Code:
I readed the Docs on the squid page but the above rules can't be reproduced to 3.1 and i don't wish to use such rules to make it transparent or hidden so i want some help to figure out why it inst transparent.

i have a squid proxy on a centos 5.4 64 Bit machine.
i can share internet on my other boxes hosting centos 32 bit and windows by entering the proxy server IP in the network proxy (centos) internet explorer (windows).
but i cannot get mails on my thunderbird client behind the proxy even though i have included ports 110 and 25 in the squid. i v heard it cannot do it as squid is not imap proxy.

I have searched and searched for a reverse proxy solution for non-website traffic. TCP but not http, on ports other than 80, 443, 8080, etc. Basically I just need a TCP forwarder that works with multiple TCP servers, WITHOUT webpage caching features. I do not need or want any webpage caching. Can squid work as a reverse proxy for TCP traffic without http? The other program I came across in searching was HAproxy. Both programs are for http but I am curious if they would work for TCP servers that do not serve webpages.

I recently removed Winblows Vista from my laptop and replaced it with Kubuntu 10.10 (I left the recovery partition on there, just in case). When I turn on the computer, the GRUB menu appears, I press enter, then a little flashing underscore appears on the screen in the top left hand corner. After a few seconds, the Kubuntu logo appears and I can log in.But yesterday I replace Kubuntu with Ubuntu 10.10. The Boot process is the same, but the little flashing underscore in the top left hand corner flashes for about 10 seconds longer then Kubuntu 10.10 did, and then a few paragraphs of text appears for a few seconds, then I am logged in automatically.Is this "unusual" boot process anything to worry about, or am I just being a noob.

Here is my query:
Squid document says that Squid accepts only HTTP requests but speaks FTP on the server side when FTP object are requested.
We call Squid HTTP and FTP caching proxy server. Does it also caches FTP contents? Is it possible to configure FTP clients to use Squid cache? When we make an FTP request to an FTP site via Squid will it be bypassed?

Alright, I edited "/etc/default/isc-dhcp-server" and set "eth0" as the only thing listed for interfaces. I also have the code below in "/etc/dhcp/dhcp3/dhcpd.conf" and I even copied it to "/etc/dhcp/dhcpd.conf" for good measure, and I can't get the DHCP server to start. As an intermediate to advanced user, I am under the high assumption that it is broken since everything in the docs has been set. I have googled for two days and cannot find a fix, so before I report it as a broken package, would somebody with more experience with the package chime in?
Configuration file:
subnet 10.0.0.0 netmask 255.255.255.0 {
option domain-name-servers 10.0.0.254;
option broadcast-address 10.0.0.255;
[Code].....
I hid my wireless setup because it contains my WiFi network info including key. This box is routing, doing DNS resolution, and firewalling just fine. I just cannot get the friggin' DHCP server to start no matter what I try.
Oh, and is it safe to delete "/etc/dhcp" or "/etc/dhcp3"? They appear to be duplicates of each other...

I have a fairly simple iSCSI setup using two devices, but they have swapped names on different machines. running CentOs 5.3 ia64, and using iscsi-initiator-utils-6.2.0.868-0.18.el5
vm1:
[root@vm1 ~]# fdisk -l
Disk /dev/xvda: 4194 MB, 4194304000 bytes
255 heads, 63 sectors/track, 509 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
[Code].....
Any way to get iSCSI to mount the devices as consistent device names ?

I want to make a transparent squid proxy server in centos. The squid proxy version is 2.6 stable. I made a normal squid server but want to make it transparent so that users do not need to enter the proxy settings in web browser. Even i searched about this on google but not getting it properly.I have two lan cards on centos system. ETH1 used for LAN and ETH2 used for WAN. And in this squid.conf i written "http_port 172.16.31.1:3128 transparent" and i also added a rule in iptables which is "iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j REDIRECT --to-port 3128" but still i have to enter proxy settings at client's web browser to use internet

I've read some posts that had no reply, someone tried to telnet to 127.0.0.1:3110 "the default port of clamd". I tried that but I got connection refused.

I'm looking for VPS provider in the US. I'm just trying to get around geo-location restrictions and I figured that the easiest way would be to get a cheap VPS and set up squid. (I'm planning on sharing it with a few friends) Anybody has any experience with any VPS providers?

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.
