But can't get the adapter to become active and pick up an IP address. Has anyone done this before? I can't get it to work. When i was testing CentOS out i used VirtualBox and worked fine using bridged networking but just can't seem to get this network card working.I've put some pictures of the config i've got.http:[url]....

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 am trying to setup a VPN using OpenVPN to allow a secure connection between my smartphone and my LAN. I have been reading an OpenVPN book and some tutorials on how to setup the server side, but I'm stuck at how to create a virtual device. The OpenVPN book says when installing OpenVPN the installer (or aptitude to be more precise) should ask me if it should create a TAP/TUN device. The thing is, it doesn't ask me anything at all. It just installs, that's it.
Most tutorials simply tell me to create a new device in the network/interfaces file. Where is the difference? What should I do now? I like having options, that is one reason I like Linux, but this does confuse me. My second question is about the IP range of the virtual adapter. Should it be in the same range as my LAN, or should I use something entirely different?
I've just arrived at uni and to set up my wifi apparently I need my "media access control which is listed as the phsyical address for ethernet adaptor local area connection." on windows you can find it by using the command ipconfig /all but that didn't work when i put it into terminal.
View 1 Replies View RelatedI 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.
Version 10.04 LTS. Installed desktop version and network worked but I needed a static IP address and the install configures for a DHCP configured address. I tried changing to static address using the System->Preferences->Network Connections application but was unable to get the system to come up with the network up.
So I manually modified the /etc/network/interfaces and the /etc/resolv.conf files. I restart the system but when I do an ifconfig, I don't see a configured IP address on eth0 (only the loopback address). If I run /sbin/ifup eth0 everything then works fine and ifconfig shows the correct address bound to eth0.
My files are as follows:
We have two recently installed centos machines, each running 5.5, and hosting an elastix pabx distro as well as a Virtual PC instance. On both machines, the network adaptor fails completely every week or so. As they are remote machines, the only option we have when this happens is a manual reboot.
I might be barking up the wrong tree here, but the only significant difference on these machines to others we have deployed is the Virtual PC instance. The machines have dual ethernet ports, with one assigned to the virtual PC. When the network failure occurs, it does not effect the virtual machine, which continues along merrily.
My expert colleague does not think so, but can anyone think of any way that our configuration could be causing the problem? If not, does anyone have any ideas on what the problem could be, or where I would start looking for information on the machine to debug the issue?
had a box lose it's virtual IP address on the eth0 card. I rebooted the box but it just would not give the card the second IP address. We rebooted several times in fact.Today admin ran 'ifup ifcfg-eth0:1' and the virtual IP was there. Nothing was changed, just that command was ran.I thought there might be a problem with the automagical stuff so I rebooted the box again, virtual IP is there and happy.Anyone know why it would not have come back on reboot and why it now does?
View 7 Replies View RelatedI'm trying to setup a CentOS 5.5 with 1 NIC to have several IP addresses on same subnet, each with different MAC addresses. I tried macvlan and multimac but both gives same MAC address (the one of physical NIC) for all IP addresses configured in ARP table on remote hosts. Is it possible to send the 'right' MAC address in ARP requests of corresponding IP address?
View 7 Replies View Relatedhow to do a virtual interface under linux. I'm using for example eth0:1 so ifconfig eth0:1 192.168.0.20 netmask 255.255.255.0 for example.
However if i do eth0:1 hw ether 00:11:22:33:44:55 It changes eth0 as well. Where should i look into for creating a separate virtual interface that's simply bridged with one of the existing interfaces that has a separate ip and hw address that the os handles.
I have one router, a linksys. It allows wireless and wired connections, as is normal. I have two XP machinesby wire to the router and three linux machines connected wirelessly. The XP machines both have IP addresses beginning with 192.168. while my three linux machines have IP addresses that all begin with 172. None of the machines is connected with a static IP address. All are automatic DHCP.I am told that the above scenario makes no sense. However, such is what I have so, I trust, the theory and the fact do not gel. I would not care except that I cannot see - using the nautilus network servers program, all of the XP computers with some of my linux boxes.

View 5 Replies View RelatedI need a small shell based program that prints the mac address of physical ethernet adapter from it's firmware. I need this utility for license generation and appliance activation. I have tried several example but none of them is flawless, The easiest method I have found is to parse the output of "ifconfig" command but it has also some drawbacks.
1. Firstly program should differentiate between physical and virtual adapters. Physical means installed on board(wired or wireless) or installed additionally. Virtual adapters are those created by VPN or created by virtualization apps such as VirtualBox/VMWare etc. I am not interested in virtual ones.
2. In case of more them one physical adapters(wired and wireless), it should print the mac address and description(name & vendor) of both/all adapters.
3. If media is disconnected then also it should be able to read the mac address and description(name, vendor) of card.
4. This one is bit complex. I know that 'ethtool' can show you the universal mac address but it's limited to use only 2 types of drivers and won't work in all cases.
I want to translate the virtual address to physical address in linux C application, how to do that?

1. Lets say I have [URL] web and mail server running. When I write [URL] on my browser, the site is coming up but when I also write [URL] and I see the same page. There is no record on apache for [URL], there is only DNS record for the mail server. What do I do wrong?
2. Apache conf. is as below; do you think is it better to write "any" on address section instead of ip? What is the difference?
Address 88.11.11.111 (ip isn't true) Port 80Server Name domainname.com Document Root /srv/www/domainname.com/public_html
3. IP Address is the same for all domains. How I can configure that; when I write the ip address on my browser, only the specific site which I choose will be opened? Whichever I created last, that site is opening right now.
How can I get the physical address corresponding to a virtual address in linux by using /proc file system

To provide with my goal:
1.) Learn about network setups on Linux
2.) Be able to maintain my own (virtual) network
3.) Configure my (virtual) network
I have a server that is on both a standard network and a virtual network, as follows: server1 attached to standard network server1 acting as Dom0 with two linux DomU guests (under Xen) I only have one network card. How do I configure server1 to have a different hostname on the standard network than on the virtual network? Here are the relevant network configuration files for server1:
/etc/sysconfig/network-scripts/ifcfg-eth0:1
DEVICE=eth0:1
BOOTPROTO=none
NETMASK=255.255.255.0

Basically a few weeks ago I decided to try Linux, in particular Ubuntu. I have it installed in my Windows 7 partition but now I am willing to take the full plunge and switch to it all the way. The only issue is I cannot connect to wireless internet. It states "device not ready". Wireless is turned on on my laptop, I am very near the source, have tried making a manual connection with the network setup. I tried the hardware tester and it found my ethernet and wireless hardware (Broadcom 802.11g Network Adapter).
I went to the package thing and looked for Broadcam. I found a package but it was already installed. I tried it manually with:
sudo apt-get install bcmwl-modaliases
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
I then heard to try "sudo apt-get install bcm43xx-fwcutter" and did but it couldnt find it.As stated before I am new to linux so I'm probably missing something easy I just beg your patiance as I learn this new operating system.
I have a Belkin N150 USB Wireless Network Adapter and a Belkin N150 Wireless Router. I cannot seem to get NetworkManager to connect to the internet. I have blacklisted the 9.10 staging driver and associated rt files. I have downloaded and built the ralink 2.3.0.0 driver. The light flashes on the usb but I cannot connect to internet.

I'm trying Ubuntu for the first time; it's actually the first time I've messed with Linux at all-- and, well, it's kind of intimidating. One of my hobbies is playing with dead computers, and long story short, I have Ubuntu installed to a partition on an external drive connected to an older Dell desktop with no internal storage to call its own. The only network adapter I have to spare right now is the rather wimpy USB one that came with said desktop. I have the CD with the drivers to it, but I think the Linux drivers on it are for a different distribution. Am I going to need to scrounge up another network card or adapter, or am I going to have to start sheepishly asking ridiculous questions regarding basic operation of the command console?

In the half hour I looked at it, I realized I forgot a lot of things. I could not even find the laptop USB. Will tring to get it to work be the typical Linux thing, where you download the drivers, do the install right, and it doesn't work? You compile drivers, set everything up right, and it doesn't work?
