My company requires a proxy server that requires a manual configuration to use. Many Ubuntu apps, however, do not respect the HTTP proxy settings.Is there anyway to modify my local firewall settings to automatically forward IP traffic to the company proxies in the same way a transparent proxy might work?Would I need to set-up my own local, transparent squid proxy which itself forwards to the company proxy?
View 1 RepliesI work for a auto dealership, and they have a proxy server that is provided by toyota that does nothing other than route traffic some specific sites they use in the dealership. We are looking to put a local proxy server in place to filter web traffic of virus/inappropriate content. What I am looking to do is set everyone's proxy settings to point to our server but when someone puts in the toyota sites it will redirect them to toyota's proxy server and out. I am not sure if this is possible or not.

It happens in Chrome/Opera/Firefox. This proxy requires authorization and works on computer with Windos XP. It worked well when I was using Windows 7 and Proxifier, now I have Ubuntu 9.10 with all available updates.

View 1 Replies View RelatedWhat I want to do is to share the internet connected to a computer with a telephone, over another telephone which is permanently connected to the pc.The thing is, that some guys found a way of making this on windows, in fact, I already set it up on xp and works like a charm, it involves configuring in a certain way the telephone,d to use 2 programs. One is CCProxy, which redirects the internet connection to the telephone, and another one, which updates the IP adress of the telephone connection to dyndns, so that I can put that adress on my second telephone as proxy, and this way, surf on the net through my home internet on the telephone anywhere. Tricky right?
Now, the thing is I don't like at all booting windows only for sharing internet with my telephone. So I want to do it in linux. I use Ubuntu and Puppy linux home.I tried setting up the connection to the modem with wvdial, and... I got connected! But hey, when I connect to the telephone, I lost my internet connection (main, cable based, the pc connection) :-S. I mean, somehow, the "active" connection for the browsers and all the internet programs is now the connection I have made with my telephone, which is plugged to the computer.Now my objective here is that NO CHANGE of active connections get done when I start the connection to the phone, and then, get a program like CCProxy, and a dyndns updater for sharing the internet connection on the pc, to the connection made on the telephone-modem wired to the computer.Am I clear? I know it is confusing, and it took me weeks to understand how it works and get it done in windows. But now... Ubuntu is what I want.

following on from [URL] I was having a little think about how to make this concept more secure. its easy enough to separate known and unknown clients out via MAC address. but that system is easier to break than it is to set up either, sniff out a mac address already connected to the system, and spoof that address.or, more simply, set a static IP on your wifi device, and avoid the redirection completely. so, is anyone aware of a relatively straight forward setup that would allow me to identify clients on my network without relying on MAC address, would more forcefully separate out known and unknown hosts (vlan??). As well as doing so without alerting them to the fact, and without requiring known hosts to do anything special, or install software. Or requiring any more hardware than I have already. (hardware = a debian box with 2 NIC's acting as a gateway between all internal network, and the billion router which handles the outside world not getting in, and a WAP attached to the internal side of the network. also somewhere I have a wifi card that I could attach to the server to replace the AP) I assume some sort of authentication mechanism is required, but I dont know much more past that.
View 2 Replies View RelatedI'm trying to setup iptables to send web (tcp?) traffic through Squid and Privoxy transparently (to save having to setup everything per browser and hoping they honor their settings). I know I have done this before but I can't find the old config nor remember the exact options needed to do this.What I am wanting specificially is for Privoxy to grab the data as it leaves the browser, do its thing then pass it on to Squid before sending it down the line, then doing the same incoming (Privoxy -> Squid -> requesting app).

At the moment I have a proxy and all the users have to configure it in the browser to access internet. I want to make the users able to browse even without configuring the proxy in the browser. but eventually it should be received in the proxy rather than giving an error to the user. I heard with transparent proxy I can redirect all the traffic from a particular network, to a particular host( ie my existing proxy).
I tried this using firewall rules. But then the existing proxy doesn't understand the protocol of the requests. I heard that it should be in the kind of proxy protocol.
I have two almost identical images of the same size that I want to compare. I'd like to over-lay them one on top of the other and vary each image's transparency so that I can compare them. Anyone know of any software that does this?

The router should handle everything automatically and transparently. All you need to do is make sure that the wireless Ethernet adapters in the laptops can "talk" to the wireless router.

I have a virtual environment, RHEL6 minimal install. On that, I am trying to run Liferay6 on Tomcat6 for the purpose of writing prototype business portals. I used the Liferay+Tomcat bundle downloaded from the Liferay website.
For security reasons, the server can only be accessed through port 80, and Tomcat listens on 8080. (I know I can run it so that it listens on another port, but I'd like it on 8080)
Goal:
Use iptables to forward traffic destined for 80 to port 8080.
What I Did:
Configure nat to forward tcp packets from 80 to 8080:
Code:
List the nat iptable:
Code:
wget to 80 doesn't work:
Code:
What I Already Checked:
Tomcat did start normally. Logs show no errors, and specify that Coyote HTTP/1.1 is initialized on http-8080. I can provide this log if need be.
Tomcat is listening on port 8080:
Code:
Code:
I get the same negative result on the VM on the server as I get on a RHEL6 VM on my laptop.
The iptables method that I described above does in fact work with Liferay6 on Tomcat6 on Ubuntu 10.10.
I have looked at this thread. I appear to have tried everything that was mentioned there.
Actual Question: I would like to know how to effectively forward 80 to 8080 on RHEL6, so that I can access Liferay on Tomcat (listening on 8080) at 80.
I have "Server A" with real internet ip 1.2.3.4 (eth0) and lan ip 192.168.1.1 (eth1) There's also "Server B" with lan ip 192.168.1.2 (eth0), I'm running an Apache Web server on "Server B", so I want to redirect all traffic from IP 1.2.3.4 port 80 (Server A) to 192.168.1.2 port 80 (Server B), using the following rule:
[Code]....
iptables -t nat -A PREROUTING -p tcp -d 1.2.3.4 --dport 80 -j DNAT --to 192.168.1.2:80 This actually works pretty good, from internet I can browse ttp://1.2.3.4 But the problem is that if I check the Apache logs, all incoming connections seems to come from 192.168.1.1 instead of showing the real source ip addresses (internet ip's) so this is screwing up all my web stats, I've been looking for hours and hours on how to make a transparent redirect, but can't find any info, I know there must be a way because my old WRT54G router which uses iptables could do it.
I have a bit of a strange scenario. I have a machine with a fixed IP (192.168.0.108), running Linux. It has an external IP 99.99.99.8 via a 1:1 NAT on a Cisco ASA/router. Port 3389 (MS RDP) is open for 99.99.99.8. I want my Linux machine to listen on port 3389 and redirect all traffic to that port to a Windows machine (192.168.0.100). In this way, my Linux box is able to respond to requests on all ports, but port 99.99.99.8:3389 connects to Remote desktop on the Windows PC. I do not have access to the Cisco NAT config. I was able to get this setup to work by using an SSH tunnel.
I ran this command on the linux box:
ssh -L 3389:192.168.0.100:3389 ergosteur@192.168.0.108
Any ideas? Perhaps using iptables or something?
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 a dell desktop PC that runs with ubuntu 9.04 jaunty jackalope and has 2 network cards eth0 that is connected to internet with an pppoe connection and is shared on eth1 for the other pc that is with windows on the ubuntu server machine is installed EHCP controls panel and No-IP, No-IP works fine but if I add a host as a domain in EHCP where I want to add EHCP {itself, problem appears. No-IP does not redirect to my IP after I added host in EHCP. EHCP is set to have the original IP of my pppoe and I tried with the 127.0.0.1 IP and the problem is still there.

i have tried setting this up in the firewall using webmin but it is not working.
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.
