Ubuntu Servers :: Redirect All Network To Squid?
Apr 28, 2010
I've been having a hard time googling and trying to get ALL network connection to be redirected to squid proxy. I couldn't find a proper configuration for ufw or iptables. The ideas are:
1. redirection rule should NOT depend on a specific network inteface, but should work with any connection type, ex.: ppp0 or eth0... 2. firewall rules can be for firehol, iptables, or ufw (the same as iptables, just tell me where to place them). Preferably ufw or gufw. 3. should not interfere on cups web interface and lighttpd server.
BTW: it's not a ubuntu server install

I have recently just got another internet connection at home via cable as well as my exisiting DSL connection. I was wanting all my web browsing that I did via squid to be redirected down the cable connection. The box has a single nic at the moment and the default route sends it via the dsl connection for the mail server that is also running on the box.I was hoping that anything that hit squid would go down the cable connection that is plugged into a router and thus I can route to 172.16.2.251 and everything will go out via cable.
I was reading about iproute2 and marking the packets and is wondering whether this is the way to go?

i have installed squid 2.6 on my centos. i have writen a shell script to ping a network and write to a file. write '1' if network up and '0' if network down. After that,a perl script will read the file and do the redirection.Perl will redirect to a fix URL [URL] if the network down and do nothing when it up. i have put my perl script in squid.conf at url_rewrite_program /my_file_path.
below is my shell script for pinging:
Quote:
#!/bin/bash
while [ 1 ]
do
HOST=143.148.137.134
[code]....
My problem is client browser are not redirect to www.google.com even the network is down. It should go to the fix URL when the user click any URL in network down situation.it just appear cannot resolve host.

I use CentOS 5.4, Squid version 2.6 , squidGuard version 1.2. Squid works properly, squidGuard also works properli. I want to redirect all requirests from [URL] to [URL]. It seems that squidguard works:
Code:
[root@main ~]# echo "http://www.sex.com 127.0.0.1/ - - GET" | squidguard -c /etc/squid/squidguard.conf
http://www.infoborder.com 127.0.0.1/- - -
[root@main ~]#
But if I want to access site [URL] with a browser which is connected to squid, my browser get me the site [URL]

We host a web server in which we are hoping to implement some form of traffic redirection based on source IP address, and I am wondering whether the squid proxy built on iptables would be capable of managing this task? Essentially we are trying to redirect traffic from specific set of source IP ranges to a "Your IP has been restricted" type of page at a different IP/FQDN.

I have an old FC2 box running Squid version 2.5. It has been running since 2003 so I am in the process of replacing it. I have a new machine with FC11, iptables, and Squid 3.0 installed.
On the old machine I use iptables to intercept Port 80 traffic and send it to Squid. By default I block all internet access and allow only sites that are in an Allowed_Sites.txt file. Within Squid I also have statements to allow certain users to bypass Squid based on their IP address.
I have set up the same thing on the new box. I have iptables intercepting the Port 80 traffic and sending it to Squid. That is working because if I remove the redirect statement from iptables all internet access is blocked.
The problem I am having is that Squid is not blocking any websites. It acts like the ACL is set to http_access allow all. I have worked on this for several hours and am stumped.
These are my Squid rules:
acl allowed_sites url_regex "/etc/squid/Allowed_Sites.txt"
acl manager proto cache_object
acl localhost src 127.0.0.1/32
acl to_localhost dst 127.0.0.0/8 0.0.0.0/32
acl SSL_ports port 443
acl CONNECT method CONNECT
http_access allow manager localhost
http_access deny manager
http_access allow Bypass_Users
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
acl our_networks src 192.168.1.0/24
http_access allow allowed_sites
http_access allow our_networks
http_access deny all
icp_access deny all
htcp_access deny all
http_port 192.168.1.254:3128 transparent
hierarchy_stoplist cgi-bin ?
access_log /var/log/squid/access.log squid
refresh_pattern ^ftp: 1440 20% 10080
refresh_pattern ^gopher: 1440 0% 1440

Here's what I'm trying to do to complete my rocking development server.
I would like all outgoing email on my Ubuntu server to be redirected to one email address (internal or external). I don't have any mail server installed yet (I'll probably use postfix unless you have another suggestion).
The reason I would like this to work is because I'm a web developer working on multiple projects. When I start working on a new project I would like to be able to test some of the forms and features in the web application (PHP) without having emails sent to the email address configured in the application. I can always change configurations but having my development server forward the emails would save me lots of trouble.
Example:
If one of my php application sends an email to: user1@domain.com, user3@domain4.com... I would like all of them to forward to myemail@domain.com

I'm hosting my own dedicated server with Ubuntu Server 10.10. I have it set up with a static local IP, and I've configured DynDNS to link up with my router and allow my server to go live to the internet. I have all the appropriate ports unlocked, with the exception of port 80. This port is blocked by my ISP (Charter) and I can't use it. Due to this, I configured my router to listen on port 81, and direct it to my server.
So, In order to view it, you need to go to the IP XXX.xxx.XXX.xxx:81 Today, I registered (www.online-self.com) in hopes of getting around my current mask (provided by DynDNS.com (omegame.selfip.com). So here is my dilemma, When I go to the host of my domain name , I want to redirect my DNS to my server IP.
I can't seem to do it though? They want a strict IP address, no port extensions. How do I get around this so that my domain name and IP address link up? I'm thinking I may be missing a step, or maybe I needed to register a domain name that simply redirects? I'm starting to get confused on what I should do next. Can I even do this?

Our company owns multiple tld's for our corporate domain (e.g. company.com, company.net, etc.). Currently, we operate the main website at [URL]. To have "company.net" et al forward/redirect to "company.com", should we use a 301 redirect or setup a ServerAlias in Apache's virtual host directive (we use name-based virtual hosting on Ubuntu Server). Are there any SEO penalties from one approach vs. the other (e.g. Google thinking you have multiple sites with the same contact + flagging it as spam)?

I have configured my Cisco firewall to redirect all its logs to my Ubuntu 9.1 server (no UI.)
Now, my /var/log/messages is getting all the firewall logs + all other logs.
I'm wondering if there is a way to redirect the logs from my Cisco Firewall (coming from UDP port 514) to another file.

I operate a home network with Ubuntu Server 10.04 with services including DHCP3, Bind9, Apache, and so on. Since I host several dozen websites from home, I have to run Bind DNS. All Ubuntu boxes on my network operate fine. However, all Windows boxes on the network seem to forget to look internally for DNS after a couple of page loads on my internal sites. The network settings still indicate that my internal domain name server is the first lookup and everything seems normal.

On my Server I have an application running. I have the External IP address of the Server registered in DNS so users requiring access from outside the office can enter a full URL rather then an IP address.
How to I change my Apache config so that all traffic that comes into the server from the URL is put over https?

My goal is a testing server with an apache virtual host for each site that I'm working on, with fairly painless setup for each new job.For example, I want http://site-a.mydomain to server this document root /home/client-a/site-a/public_html (or something to that effect)Ideally, DNS will use a wildcard to point http://anything-i-type.mydomain to the testing server, and apache will have a dynamic virtual host definition that will do a little magic so that I won't have to mess with DNS records or add a new virtual host each time I add a new site for a client. I'll worry about that when I get there, just put that out there in case anyone has any tips! for now I just have one little problem that's hurting my mood-
It looks like I've got my DNS server working just fine, so yay there- BUT my first attempt at adding a virtual host isn't working quite how I expected- meaning that site-a.mydomain now serves up the correct document root, but when you put http://site-a.mydomain into the browser's address bar, the address bar is then updated to http://10.0.1.100/site-a/public_html - bogus!! I must be missing an option like "FunnyBusiness Off" -
root@ubuntuvm:/etc/apache2/sites-available# vim client-a.mydomain
<VirtualHost *:80>
UseCanonicalName Off
ServerName site-a.mydomain
DocumentRoot /home/client-a/site-a/public_html
</VirtualHost>2

Is there a way I can redirect messages from kernel ringbuffer to a logfile, e.g. with rsyslogd? With redirect I mean that the messages do no longer appear in dmesg, but only in the logfile.
In my case that should be iptables log messages.

I have several web servers running apache on my LAN. Each internal server hosts a number of domains.I would like to make these available to the internet and make sure they all get to use port 80 and 443.My idea was to put Apache on the firewall and have all http(s) traffic from the Internet to my firewall be redirected by Apache to the different internal apache servers. This, in theory, would allow me to keep the standard http(s) port.
Can this be done? I was thinking of mod_rewrite and mod_redirect but in all honesty, I'm a little at a loss on where to start.Can someone point me to relevant documentation or give me the basic idea on how to start?

I'm trying to set up a framework where people connected to same wifi connection can enter a local site for developing purposes.I want them to be thrown to a local copy (development copy of the site) when they type in www.development.loc in the browser.I don't want to connect the world, only people connected to my wifi.Anyone willing to help by stating what I need to edit to :1. Allow me to access local copy of site that's on computer (located : /var/www/developmentsitename/) using www.development.loc in browser./and2a. What do I edit to create the server accessible by other computers connected to same wifi connection. 2b. If another computer can connect to this site now, can we create a virtual desktop setting in which workers can work as if they have their own partition on the server to work on and upload work onto the development server.

I believe I finally have a very secure config for apache2 that will only use SSL or port443.
Problem is how do I redirect all my users who dont type in https:// to the proper SSL port 443?
Do I have to create Virtual Servers? If so how?
Or is there a Redirect command?

I tried to setup a home server that will redirect the internet traffic through the server before it reach the client. Because i don't want to install anti virus on every machine, it will slow them down a lot. There are some anti virus for ubuntu. Most of my home machines are running windows, which is a pain with virus.
p/s: I'm running 1 ubuntu server 10.04 and the rest are windows 7 machines.

how to redirect network traffic to a new IP address using IPtables. I am using Baffalo router and the rtos used is DD-WRT. Basically, I want it so that any connection going through my router to a specific IP (say, 192.168.11.5) will be redirected to another IP (say, 192.168.11.7) so any outgoing connections made by a program that is attempting to connect to192.168.11.5 will instead connect to 192.168.11.7.

I'd like to take any audio that would normally come out of my laptop's speakers or headphones and have it come out of my TV's speakers without using any wires or hardware that I don't already have. My TV is connected to my LAN via a Roku box, which has an SDK that I can use to write my own channel to handle the audio stream coming over the network and output it to the TV.
What I don't know how to do is capture the audio destined for my sound card. Is there an easier way than writing my own driver that pretends to be a sound card driver but really takes the sound data and streams it over the network?I'm not looking for anyone to do the work for me, just some help pointing me in the right direction.
