I have a problem in my server proxy.I'm using the debian etch distribution, only that now started showing this error:

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).

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 am trying to set up my squid3 proxy as a transparent proxy - right now, I have to manually configure browsers to access via proxy. I understand that I have to put some rules into Iptables and also some further directives in the squid.conf.
I have a couple of specific questions. The proxy server is running on a Ubuntu 10.04 workstation and this machine also acts as a dhcp server for the network. I have just one subnet , namely 192.168.0.1-254 There is only 1 network card. Is it much easier to put in a second network card or is it just as easy to configure the existing lan card as a dual IP?
Is it necessary to configure these 2 IP's ( whether they are via 2 lan cards or dual IP on single card ) to be on different subnets. i.e ETH0 192.168.0.1 and ETH1 192.168.1.1 or is ok to have something like ETH0 192.168.0.1 and ETH1 192.168.0.254 ( where ETH0 is the one facing the LAN and ETH1 points to the modem router / switch i.e The Internet ) Where specifically do I save the Iptables rule configuration file and what must I call it ?

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?
View 1 Replies View RelatedI have a few friends that have seen me bypass firewalls with a socks proxy (SSH). I explained on how it works and how secure it is for browsing the Internet and checking your email in public places. I had at least 6 asked me if I could set up an account on my server for them and they would pay me! Now what I wanted to know was how I can set this up in a server and website where they can register an account and pay me through PayPal! I don't need help setting up the site! Just on how to set up the server to automate this. What tools are needed (ex. ISPConfig, jailkit.... stuff like that?) I don't mind doing this manually but if I get more people that would like this I don't really want to do every single one.

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 5 Replies View RelatedI am setting up a virtual server. Ubuntu 11.04, "minimal provider image".UFW was disabled by default. I set it to default deny. Allowed HTTP, SSH and other standard stuff, and enabled it. All seems to be OK. Adding one rule to block some annoying security scanners causes ping not to work. I'm not an Iptables expert, but it looks OK to me. I got it from some website, rather than invented it myself, but modified to to fit the ufw config file syntax. What in that rule prevents pings?!? It seems completely unrelated.

I've been trying to install Ubuntu Server onto Microsoft Virtual Server at the request of my boss, and I've been having an issue I cannot seem to work around. Now my background on Ubuntu and linux in general isnt amazing, I have configured server at home to act as a file sharing platform and a media server, but thats about it.
Now I've gone to install it on the MVS at work and once the install completes, I recieve the following error: Hypervisor error.JPG
I've tried running the install but limiting the resolution, but from what I can rememeber server doesnt install the GUI to start with, so it should just be showing me the standard CLI.
I did a basic installation of Debian, which will be used for a mail server. I Installed the bind9 and did the configuration of the zones and created the files in the directory / etc / bind.
After the process I typed the following command to test my DNS:
nslookup mail.hotelpart.com and presented the following error:
Easier to stay I put my files in message: The files named.conf, db.hotelpart.com and db.111.20.11.200.
I have a server that i built as 9.10 Ubuntu a while ago. It's been running through a proxy server that i set as an export in /etc/profile. Recently i upgraded it to 10.04 Ubuntu.
Now i want to get rid of the proxy server. I removed the export in /etc/profile. I've tried restarting the network services, reloading the profile, rebooting the machine, setting a blank export, and a few other things...but it's still using the proxy!
I've tried grepping various folders but the only other place i can find a proxy setting is in the apt config (which i don't think would matter?).

View 2 Replies View RelatedI 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 have a laptop running Ubuntu (not the problem) and I want to connect to a FTP server. Filezilla works really well and so does good old ftp. But, the FTP server I need to connect to will only accept connections from a white-list of addresses. My office IP is static and is on the list. Thus, connecting to this FTP server from the office is a piece of cake. But, I want to connect to this FTP server from home. Connecting to it directly from home is impossible because I have a dynamic IP address here at the house (surprise) so we can't just add my home IP address to the list.
Fortunately, I have full admin rights on the network at my local office and I installed cygwin on the Windows 2008 server. I can successfully connect to it using ssh. That gets me half way there. I can securely connect to a machine that is allowed to talk to the FTP server. I'm half way there. Now I want to figure out how to forward my ftp port over ssh through the server at the office and to the FTP server that I really want to connect to.I've tried various incantations of ssh and I can't seem to come up with the right combination. Anyone have any experience doing something like this? In affect, I want to use ssh as a simplistic proxy and it need only really handle a single port.
