We have the following school project that I can't seems to make correctly:We need to make a whole subnet communicate with the internet through another subnet's gateway using iptables, with a difficulty option, only 1 NIC.I know its seems complicated, but it's not that bad. Please keep reading and let me explain.Let's say we have subnet (number 1) = 10.1.2.0/24, gateway 10.1.2.1.I have another subnet (number 2)= 192.168.1.0/24, gateway192.168.1.1Subnet 1's (10.1.2.1) gateway doesnt have a WAN connection.Subnet 2's (192.168.1.1) does.Which means all 192.168.1.XXX can communicate with internet, while all 10.1.2.XXX cannot.Not, the goal of the project is to give 10.1.2.1 a possibility to NAT packet comming fomr it's subnet to 192.168.3.1, so the subnet 10.1.2.XX will have access to the internet.
Now, since 10.1.2.1 (the gateway) only have 1 NIC, we make it hold virtual IPs.eth0:0 = 192.168.1.35 (static)eth0:1 = 10.1.2.1 (static, begin the 10.1.2.0/24 gateway)The routes are OK and I can ping correctly on both subnet.I can even ping the internet from eth0:0 !! (192.168.1.35)I tought using the following iptables command from the 10.1.2.1's machine would do the trick:iptables -t nat -A POSTROUTING -s 10.1.2.0/24 -j SNAT --to-source 192.168.1.35But for some reason, 192.168.1.1 doesnt even receive any packet from it's log, except when it's not NATed (when it comes directly from 192.168.1.35), which let me think the iptables command above doesnt work correctly.
I have a ATI Technologies Inc RV530 [Radeon X1600] Card which used to work fine under Squeeze until some weeks ago, after an update in didn't anymore and since I wanted to install to Lenny anyway and did a clean install of Lenny and now the card hardware acceleration doens't work. I followed url.
Since I am using a backports kernel I installed firmware-linux-nonfree from lenny-backports.
I would like to configure and SAN disk. But I do not have a physical SAN disk. Is it possible to create and configure a Virtual SAN disk and work on it with virtual machines?I have around 400GB of space in my Laptop.
I'm trying to ssh into a virtual installation of ubuntu I have, named "ubuntu-x86" but I can't get it to work for some reason. I have two network cards, both assigned to NAT, on the virtual machine, but one has a static IP address, while the other uses DHCP. For some reason, the command:
I'm not sure if this is the right category to ask for help but here it goes:I have a laptop with ubuntu 10.04x64 and i have bought recently a samsung xl2370 which has a max resolution of 1080p but the maximum resolution my laptop recognizes is 1440x900 is there any way to solve this?
When I create virtual ethernet interface and do a ping -I <v_int> <host> the outgoing address is the one of the physical interface and NOT the virtual interface.Is there no chance that trafic will go out with virtual interface address??Incoming trafic is done well i.e. responds to the virtual interface have the virtual address.
My problem is that I have 2 modems and want to check both default gw behind the modems. If I do a "normal" ping both are reachable over default route even the modem which is not the default route will not work because ping goes over the working modem.So I have 2 routing tables and want to route the virtual interface to one modem the other to the other modem
I need a Etext reader to help me read my txt books. I can not use the RFBD or get the Virtual box to work! Both tread told me to Not Try! so what is a etext reader for the txtbooks.
I don't know if I'm posting in the right box - I'm new to both Ubuntu and this forum so please bear with me. Thing is, I spent almost 2 days trying to find a web server that meets my likes. I tried like almost every well known web server, be it Apache, Lighttpd, Nginx, and Cherokee, one by one. For each I was successfully in getting PHP up and running, but was never able to configure the virtual hosts.
I'm 99.99% sure that I - for multiple times - followed correctly the online how-to's. Especially Cherokee, I did exactly the screencast (which is just 2 steps, as Cherokee has a GUI for virtual server setups). Strange enough, with each web server the virtual hosts thing never worked for me. I always received "Server not found" error. I tried with Firefox and Google Chrome. Currently I'm on an Ubuntu 9.10 (32bit) box - I reinstalled this one over the 64bit, to vain.
Don't know if it's a problem with my DNS, but I have another machine running Windows 7 with the same DHCP settings (means same DNS and IP range). Virtual hosts work fine there on an XAMPP installation.
Apparently the Xen kernel version doesnt work on Virtual Box. Didn't even know I had that version. All I can see is I386 and x86_64 version. Anyone got any experience with this point with in the direction of the correct ISO to work on a standard PC?
Virtual Box doesn't work under ordinary user, though this user is in vboxusers group. Under SU it work normally. This happied after upgrage to 4.0.10-8.1 version from obs://build.opensuse.org/Virtualization community repository. In Oss repository there is 4.0.4 version.
Here the massage, that appears after start of Virtual Box under ordinary user: "Failed to create the VirtualBox COM object.
The application will now terminate. Ditails: Callee RC: NS_ERROR_FACTORY_NOT_REGISTERED (0x80040154)
I'm running Virtualbox on Windows Vista.I have a Microsoft USB mouse (it says "Comfort Optical Mouse 3000") with left and right buttons, and a mousewheel in the middle.If I press down on the wheel, it pretty obviously makes a "click".I'm running Debian inside Virtualbox, and it's working great, but middle-mouse-click does nothing.Left and right click, and scrolling with the wheel, work fine.Is there any way to get middle-mouse-click to work in my virtual machine?
Having trouble visualising how IP-Based Virtual Host (with SSL) would work. Here is my vhosts.conf file:
Code: #Define Name Virtal Host NameVirtualHost 10.10.0.54:80 #Used to replace the main server host. The log file will reside in /var/log/httpd/error_log
[Code]....
How will it work? I will need to forward port 443 to the 10.10.0.55 interface right? Without doing that, there is no way this is going to work... is there? And that means that I can't run more than 1 ip-based SSL virtual host on one machine because I can't forward 443 to two different interfaces.
Also, do I use internal ip address or external ip address in the <VirtualHost > tag? I only have one static public ip.
I have an appliance called my_appliance.raw. To start the appliance locally, I use:
[code]...
After that I would like to ssh into the guest from the host but just the ssh command doesn't work. firewall is disabled on guest. the ip I use is the one that ifconfig shows when I run it on guest. sshd is running.
I created a new virtual host in Apache using Webmin and am having trouble getting it to work. When I created it, I opted to create the config file as a "New file under virtual servers directory /etc/apache2/sites-available". So now I have a default config file /etc/apache2/sites-available/default and a new one created by Webmin at /etc/apache2/sites-available/webmin.1412323.conf. It seems like the settings in that new Webmin config file aren't being picked up by Apache -- when I try and browse to mywebsite.com it shows my root /var/www folder, not the subdirectory /var/www/mywebsite.
Is there a way I can tell Apache to include the new Webmin config file for the virtual host or should I just copy the directives into the default file at /etc/apache2/sites-available/default? It seems like Webmin should automatically configure Apache to work with any newly generated config files.
I've been learning linux for a while now with half an eye on making a career out of it in future. One sizeable gap in my knowledge at the moment is networking. Is it feasible/desirable to set up a network of virtual machines to use as an environment to learn networking? My budget is non-existent so I was hoping to be able to get a basic understanding of the principles from installing a few desktops, a virtual gateway etc on VMware workstation on my laptop, and doing a lot of reading online.
Is this feasible, or will I just end up learning about virtual networks instead of real ones? Also how much power would be required, because my 3GB RAM lappy has just gone bang and all I have now is a (new) 1GB RAM lappy.
apache virtual host to limit the concurrent connections of virtual hosts? Taking into account the host of each virtual user's home directory can also have more than one subdirectory, which should be restricted to a subdirectory. Is beyond the control of the operation of these sites in a subdirectory. Best local restrictions or limitations to the overall situation.
I have spent considerable hours searching forums and googling. I have yet to find out what "lm-sensors acpitz-virtual-0 Adapter: Virtual device temp1:" is actually looking at. I have an Abit IP35 motherboard with Ubuntu 9.04 installed.
Here is the output from sensors:
Virtual Device Temp 1 keeps going up to 121 degrees and the computer shuts down. None of the others overheat. Also, my bios does not show my voltages to be set like it lists above. The bios in the motherboard is the latest from Abit.
I'm having an issue with setting up the virtual hosts on my web server. I have 2 virtual hosts (example1.com, example2.com). example1.com works but example2.com is sent to the index file of example1.com. I did some searching on google and it seems the problem might be with my /etc/hosts file.
First virtual host that the second is also directed to...in sites-available/sites-enabled (note port 80 is blocked by my isp so I use 8080)
Code:
Second virtual host file
Code:
And my hosts file
Code:
# The following lines are desirable for IPv6 capable hosts
Also I'm using a dyndns.org...would that make a difference?
I have some webserver that does virtual name servers for sites. I amd having a second ISP put in tomorrow. How do I have one interface and give it two public IP's? I will use two A records on DNS so it will use either A record to find the host.
Can I copy my virtual box VM windows XP virtual-machine files to another Linux computer and run the machine on that computer while I keep on running it on the original computer?
This question is about technical possibilities, not licences.
How do I program a virtual machine to auto-start/boot upon boot up of the host system? I am experimenting with SNORT network intrusion detection system and have installed it inside a virtual ubuntu box which I want to start automatically.
I have this annoying problem since day one.I am testing out Red Hat RHEL5, everything is fine except DNS look up.If I ping www.google.com, it doesn't work, ping ip address it all works;if I bring up browser, put www.google.com it doesn't work, can't find the name, however, simply put ip address there it works.My DNS seeting seems ok, and the DNS works from Windows box.
how would I simulate on any virtual environment (VMware/VBox/ KVM/QEmu) setup of SAN, SAN switches and 2 HBA cards connected to the SAN switches so that I can be good at configuring multipathd?
