I've two internet based server ( xx.xx.xx.xx and yy.yy.yy.yy ) The Y server is running VNC server and is responsible for answering to VNC sessions. But I need to hide the IP of Y server so I want X server to be as VNC Proxy and redirect all VNC sessions to Y server.
I guess the best way is to use iptables but actually I can't get it working so
I want to settup a proxy server who just redirect the internet connection to my second computer. I try Squid Proxy but its too complicated for me. Can you sugest me another more simple program to do what i want?

I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).

View 1 Replies View RelatedI have been beating my head for the last few weeks on this problem, (although I have been taking the wrong approach, it seems).
I need a gateway to direct web traffic to three separate servers/domains. I have been trying to do this with both a dns server and , (seperatly), apache server to forward requests. The dns server was a no go, and <i can only get apache to redirect http and ftp.
After Googling this ALOT, I believe that what I need is a gateway server to redirect my traffic to the 3 different servers. I have been reading about using using nat and iptables for this and was wondering if anyone had any advice/suggestions on this. The other thought I had was to use something like pfSense to create the gateway, but I am still reading the documentation, and I am unsure if this approach will work.
The issue is that my CentOS workstation is in a vlan from where the Intranet's DNS servers are unreachable. For browsing the web there is an ISA proxy server, which I presume resolves DNS for my firefox. However, wget, host, ping and aria2c fail to get any sort of DNS resolution since they're being run from command line.I have exported HTTP_PROXY value, which provides me internet access on console, but,only when I connect using IP address. It fails on name resolution.
My question is:May I redirect the DNS queries to my home PC which would be running a DNS server on a non standard port?I was thinking of putting nameserver 127.0.0.1 in /etc/resolv.conf and then put iptables rule to redirect 127.0.0.1:53 UDP to a.public.ip.address:3535 UDP..I don't know if I am shooting blanks or what, I am not very much aware of this kind of setup.My main need is to provide DNS resolution to console apps.I want to utilize my company's idle bandwidth for bulk downloads, so, using proxy, SSH tunneling through my Home PC is out of question.

View 3 Replies View Relatedwe need to log web access of a certain set of users for analysis. We decided to setup a proxy server which just logs all the requests but does not do anything else like caching/access control etc.All users will be using a fixed set of computers and hence we can redirect their requests to the proxy. I came across Squid, but found it to be too heavy for our requirements. Is there any other proxy-server software that is good enough for what we want or is Squid the only way?

I explained on how it works and how secure it is for browsing the Internet and checking your email in public places.

View 4 Replies View RelatedWe currently have a SUSE Apache2 reverse proxy server setup to reverse proxy (proxy_mod) our GroupWise Web Access server. Our SUSE box is located at www.domain.com. Our GroupWise Web Access server is located internally and is called GWMail. We are in the process of migrating from Novell to Windows, so we will have an exchange server with OWA access running on a Windows Server 2008 IIS7 box. That one will be called EXMail internally. Right now when someone goes to www.domain.com/gw/webacc it goes to the GWMail internal server from the outside world. This was all set up by previous techs who used Linux more.
We would like to set up reverse proxy to be able to reverse proxy to the Exchange Server from the outside world. Unfortunately the snag we are running into is that Exchange needs to run on port 443, and forwarding to port 443 has been a little tricky. I've read elsewhere we need to implement a generic TCP proxy, such as IPtables. what we need to do to get our SUSU Apache2 server to be able to reverse proxy to our Exchange server on port 443. For the save of argument lets call our SUSE server ExtranetServer. Below is our default-configuration.conf file's configuration:

View 3 Replies View RelatedI'm trying to workaround a limitation in a server application. The limitation is that I can only connect to a LOCAL mysql database. I am trying to fool the server in to using a remote mysql database. I was hoping to do this by simply forwarding 3306 to another server on the same subnet.To that end I've set up iptables rules to forward all connections to port 3306 to a non-standard mysql port on a remote server. This works, except that I need to deal with the loopback interface in a special way and I'm stuck.

I have been struggling to configure a squid proxy server on my ubuntu 11.04 VPS.
Following these instructions[URL].. it is all good BUT I don't want to have to SSH tunnel into the server. Just want to have a proxy set in my proxy server settings in firefox/chrome. Even lock the proxy to certain static IP addresses so no one else can use it except IPs I designate.
1. Can this be done without a VPN or SSH tunnel ?
2. What is the best way to put some security on the proxy server ?
I dont know my question is right or wrong.I want to know can i use apache as a proxy .Is there any relation between apache and squid proxy.
View 1 Replies View RelatedMy ISP seems to be having some configuration problems cos of which I cant download certain files (mostly exe and msi and some rpm files) as the download either doesnt start (firefox download window showing "Starting..." all the time) or download gets stuck at some point of time.
However I have access to my college computer through SSH using public key authentication and my college computer has internet access 24x7. I would like to be helped with 2 things:
How do I use the internet through my college computer? Like when I use the internet, the requests go through my college computer so it must appear that the requests come from my college computer IP while I use firefox from my home computer How do I configure yum to download packages through my college computer? I want to setup yum to use the IP of my college computer to download the packages.
I have access to a server via ssh. I'm allowed to install things in my userspace. Furthermore, I'm allowed to use the bandwidth. I paid for access to this server, so they're pretty much ok with me doing things with my space. They told me not to store over 20 GBs of data, and I've kept to that rule.
Basically, I want to be able to turn it into a proxy. So, in a way, I want to redirect all of my traffic to that server. If I have a request, it goes to the server, and any replies come directly to my box.
So, this would be a proxy, right? I only have SSH access, I think. Maybe I have some other forms of access, but I can't remember.
How would I go about doing this?
Here's what I have in mind:
(my box) ----request---> (the server) ---> {internet}
(my box) <----reply/incomingdata---- (the server) <---- {internet}
