TWO NETWORK CARDS

• Routing between two network cards

  I have 8 fiber switches that are configured to use a private network for management.

  The subnet is 192.168.8.0/24.

  I have a W2K3 (SERVER A) server with two NICS, a NIC (192.168.8.1) is attached to

  the 192.168.8.0 subnet and the other (192.168.100.14) NETWORK adapter is attached to the subnet 192.168.100.0/24.

  I put up two persistent routes of road between these NICS using the following commands:

  Pei route add 192.168.8.0 mask 255.255.255.0 192.168.100.14

  Pei route add 192.168.100.0 mask 255.255.255.0 192.168.8.1

  I have an other W2K3 server (SERVER B) with a single NETWORK (192.168.100.12) card that must be able

  to connect with the fiber switches via tcp/ip. Packets should be routed to this server.

  On that I put in place a permanent route:

  Pei route add 192.168.8.0 mask 255.255.255.0 192.168.100.14

  Everything works very well.

  (Assumes that the SERVER-A and SERVER B are now turned off)

  I'm trying to reproduce this on my VMware ESX Server 3.5upd3.

  ESX server has two NICS, one attached to each of the subnets. I create a virtual machine to replace SERVER-a

  with the same number of network cards and the same IP addresses.

  I then create routes as follows:

  Pei route add 192.168.8.0 mask 255.255.255.0 192.168.100.14

  Pei route add 192.168.100.0 mask 255.255.255.0 192.168.8.1

  PROBLEM: as soon as I add the second route I can no longer ping any server on the 192.168.100.0 subnet.

  This also causes connections to last very long.

  Do I need to implement routing between network adapters ESX scale to make this work?

  If so maybe want the command look like? If not, what could be my problem?

  Thank you for the helpful answers

  If you want to configure your machine as a router, you will need to notify the router is the next hop.  Now, the next machine break is its own interfaces, which will not work.  And since you are running some sort of routing protocol, provide two solutions to exit the server is not a good idea, because he doesn't know that one to use.  It will use 1 for some and another for some.

  Do what you intend (or I think you intend), you must delete the static routes and choose a default route, which will be your next jump.  This should be another router in your environment.  Then, the other servers that you want to route via ServerA, ServerA interface on this segment would remind you.

  Hope that makes sense.

• Communication between two network cards on windows 2003

  Hi all

  I need your help.

  I have a machine virtual windows 2003 with two network adapters.

  NIC 1 - external - 192.168.1.101

  Map NETWORK 2 10.10.10.1 - internal -.

  I've configured to operate as a DC and DNS serving 10.10.10.x network.

  DNS is configured to resolve before on 192.168.1.1 as redirector DNS requests.

  I have other machines connected to the 10.10.10.x network.

  They can ping 10.10.10.1, they can ping 192.168.1.101 but not 192.168.1.1

  I want to just be able to talk to 192.168.1.1 and be able to access the internet.

  No firewall between the two.

  Command-line may help, but I would need your help.

  Network configuration / routing / two network interface cards / NAT - leased / dedicated Dell R210 running VMware ESXi 5.1.0 build-799733

  Hello

  I'm trying to understand how to configure a dedicated server of Dell R210 rented running VMware ESXi 5.1.0 build-799733

  This dedicated server is rented www.online.net and sits somewhere in France. One of its network adapters have an IP public 62.210.177.20x. The other NIC is here, but I do not understand how it is configured. According to the www.online.net portal, the other NETWORK card has or should have an IP 10.90.116.20x. And I am obviously set up is to have some virtual machines running and be able to access the Internet. I have access to the console of the server Dell through iDRAC and since I could see, one of the network adapters in the IP is 62.210.177.20x defined, and the other has been shown out of service. I managed to make it appear the other interface but I cannot find anywhere how to assign the IP address 10.90.116.20x to this 2^nd network adapter. But then again I don't even know if I should or if I need to assing a IP address to this 2^nd network adapter. What is the cable connected even for this 2^nd NIC? I do not know. Should it be - I'm not either. I don't know French and manuals/instructions on www.online.net are in French. I can try an online translator, but I don't think that what I'm looking for is explained. How do I get this set up? I have to do something about the ESXi on the server console? This interface 2^nd should be in place, or it must be down as if it was originally? Yesterday after watching someone videos on YouTube, I added the second virtual switch and moved the virtual hosts of this switch 2 and he entrusted the 2^nd NIC. But that 2^nd NIC had a red X next to it probably indicating that it was disconnected the 2^nd form virtual switch. Today and now I have managed to access the ESXi console server through iDRAC, I bring the 2^nd NIC, and now both network adapters are assigned to the virtual switch 1^st . But I think that a NIC should be attributed to a single switch and the other card NETWORK on the 2^nd switch. I'm just a desktop guy with enough knowledge to be dangerous J if you / someone put in steps how and where to set them up it... PLEASE

  Thanks in advance

  Network configuration

  • VMware vSphere Hypervisor is an "operating system" for pure virtualization and support NAT or routing. Therefore, only a real bridge configuration can be used.
  • To use a subnet additional IP must be configured as a router VM.

  If I understand the above, I need to show some VM and set up as a router? If the virtual machine that will act as a router must have two network interfaces, where it is connected to a switch and the other to the other switch network card. Am I do? The YouTube video that suggested, but I thought that maybe / somehow ESXi can route packets between the two network cards, but from what I read, ESXi can route packets. Do I need to order an additional / extra / 2nd IPv4 address so that it can be assigned to the interface of the router?

• T440p: 1802 unauthorized network card, none can not start the update of the BIOS

  Yesterday, I received my Lenovo Thinkpad T440p.

  I wanted to install Linux immediately, but apparently 14.04 isn't able to boot with the 2.22.

  The solution suggested in various forums was to downgrade the Bios to version 1.14, I did using the Windows

  Installation program provided on the Lenovo's Support page.

  After reboot, I get the infamous error 1802: card plugged unauthorized network, probably because of the whitelist is not not to date.

  I was told by the support hotline to update my BIOS to another version by using the bootable CD images.

  I have burned different versions of them, but none of them would start.

  The error will appear right after the start of the Thinkpad screen. I can't get into the Bios. Press a button (Esc F1, F11, F12), entry etc has no effect either.

  How can I install another version of BIOS? Is there an extra step that I take, in order to update the BIOS through a bootable CD?

  Any help is very appreciated!

  Hi x220forMe

  After discussions with the Lenovo support and have been assured that it would not affect my warranty

  I removed the two network cards and was able to start. It turns out that the problem was the map of the Sierra.

  I don't really count on this map, but I find Lenovos "Whitelist" exasperating and totally stupid.

  in any case, thank you for your efforts to help me!

• IMAQdx mind traffic on the second NETWORK card

  Hello!

  My system:

  -Labview 2011 SP1 with NO Vision and IMAQdx

  -Windows 7-32 bit

  -2 NICs (Intel Pro 1000)

  On a NIC (subnet: 192.168.0.x - Intel pro driver) a sick Ranger is connected. Store it works with Studio of sick Ranger or the Labview Toolkit Ranger.

  On the second NIC (subnet: 192.168.1.x - Realtek dreiver) a Vision of Basler GigE camera is connected. It works with the grun80 pylon Viewer and IMAQdx GigE functions in Labview.

  If I start the acquisition of two cameras using the Studio store and Basler pylon Viewer (no Labview) both cameras acquire images at high speed without any interference.

  If I use Studio Ranger or LV-store Toolkit for the Acquisition of store it works selection UNTIL I have start a Labview VI containing the screw IMAQdx to acquire images of the Basler camera. As soon as the VI performs stops Acquisition of Ranger and Ranger loses the connection.

  I guess the driver IMAQdx is somehow interfering with two network cards.

  Suggestions how to exclude one of the NICs of IMAQdx driver or can someone tell me what is happening on the network driver layer when loading of IMAQdx?

  The purpose of my request to LV, is that both cameras can be used at the same time!

  Thank you!

• Two networks

  Hello

  I have two computers connected to a router via LAN who access the Internet through it. Both are active DHCP.

  Now these lots of computers in the movies I want to watch through Asus O! Play Media Player. For this sake I had implemented another local network through another router and wireless LAN adapters in the computer. At present, this is disabled because it is confusing the system to be used for access. How to set up the second network. Should I put static IP addresses that are in the range the second router can detect which media player is connected? Or a best possible solution so that my computers should not plant? They are old enough!

  Thanks in advance. Any help is appreciated.

• The Linux host, guest of WinXP, host has 2 network cards, how to choose which NETWORK adapter to use?

  I know it's something of an FAQ, but several hours spent on these forums and Google search gave me nothing of what works.

  All the solutions I've seen assume Windows as host and (something) as a guest.

  In my case, the host is Linux (CentOS 6.4) and invited is Windows XP.

  The host has two network cards, one on a 10.x.x.x network and the other on 192.168.x.x network.  In the guest virtual network adapter connects to the network 10.x.x.x.  I want it on 192.168.x.x network.

  I would be happy if I added another virtual network card and one of them connected to each network, but two of them connect to the 10.x.x.x network (with 10.x.x.x different IP numbers).

  The solutions I've seen indicate that under the Virtual Machine-> network adapter settings-> network connection, you click on the button "Configure the adapter" and load of come from there.  It would be great, but I have no button "Configure the adapter" or something like that.  I have a button "Advanced", but that just allows me traffic into and out of the butterfly and set a new MAC address, that's all.

  Because the host is Linux, I have also no equivalent to vmnetcfg.exe, at least none that I can find.

  So, where should I go from here?

  VMware Player is the version 6.0.0 (freshly upgraded 5.0.2 this afternoon).  I tried with version 5.0.2 and got the same thing.

  Thank you...

  You will need to use the virtual network Editor, although first you may need to create symbolic links.

  The first symbolic link already exist in a Terminal using the following command. Note: If connected a root the sudo command is not necessary when the.  Tip: Copy and paste the commands!

  ls-l/usr/lib/vmware/bin/vmware-netcfg

  If it exists, the output should be similar to the following.

  lrwxrwxrwx 1 root root 13 29 Sep 08:17 / usr/lib/vmware/bin/vmware - netcfg->/usr/lib/vmware/bin/appLoader

  At this point, you can simply use the following command to bring the virtual network Editor.

  sudo/usr/lib/vmware/bin/vmware-netcfg

  However, if you want easier access creates a symbolic link in: / usr/bin

  sudo ln-s/usr/lib/vmware/bin/vmware-netcfg/usr/bin/vmware-netcfg

  If the symbolic link/usr/bin/vmware-netcfg does not exist, then use the following command.

  sudo ln-s/usr/lib/vmware/bin/appLoader/usr/lib/vmware/bin/vmware-netcfg

  Then, to facilitate access to create a symbolic link in: / usr/bin

  sudo ln-s/usr/lib/vmware/bin/vmware-netcfg/usr/bin/vmware-netcfg

  To bring up the virtual network in a Terminal editor use the following command.

  sudo vmware-netcfg

  In the virtual network editor disable automatic bypass on vmnet0 by selecting the network map target in the bridge to: list box.

• Grouping of NETWORK cards causing the ESXi to retransmit ethernet frames received.

  I had an HP Proliant DL380 G5 ESXi 5.1.0 connected to a Cisco 3750 Switch stack.

  All by performing a tcpdump on a host without a report, I discovered that he was under the bombardment with ethernet frames for the MAC address of a computer virtual located on a host across the data center. After a few brief troubleshooting, I discovered that I was able to stop those erroneous frames by disabling NETWORK adapters on my VMWare host group.
  
  I believe that in my situation when ESXi is configured to use two network cards to all frames received on vmnic0 and retransmits them on vmnic1 and vice-vesa. I experienced these symptoms when ESXi is configured for failover with an active adapter and adapter mode standby and I also experienced the same symptoms in the following load balancing configuration.
  

  
  

  Symptoms: some time after activating the load balancing, all frames Ethernet for the MAC address of a virtual computer on the affected host are broadcast on each switch port in the entire data center.
  
  Steps to reproduce:
  (1) implementation below configuration.
  (2) unplug the ethernet cable connecting vmnic1 and switch1 port gi2/0/4
  (3) run the host 1.1.1.1 EI - n - q tcpdump on any machine physics linux in the data center (don't even have to be connected directly to 1).
  Confirm there is no packet seen with the IP address of 1.1.1.1 destination
  (4) plug the cable between vmnic1 and switch1 gi2/0/4 port ethernet
  (5) wait 60 to 120 seconds
  (6) watch a burst of frames ethernet with the destination MAC address of the VM (which owns 1.1.1.1) in the output of tcpdump

  I apologize for the delay in my response.

  Unplug physically 2 cable NETWORK card on the host and configuration mirrored port on the switchport to 1 NETWORK adapter of the host, I have been able to confirm that the host VMWare issues guides on NIC1 with a destination MAC address of one of its own VM.

  After carefully reviewing the captured data, I noticed that the destination frames wrong "02:bf:cb:50:a2:76" MAC address actually belonged to "Local Area Connection 1' one of my Windows 2003 Server WHAT VM installed on the suspected host.

  Dig a little deeper, I discovered that this virtual NETWORK card is presented to the operating system as
  Name: Local 1 network connection
  "Type: VMware Accelerated AMD PCNet adapt."
  MAC: 02-BF-CB-50-A2-76

  But the configuration of the virtual machine in vCentre is
  Name: Network adapter 1
  Type: Flexible
  MAC: 00: 0C: 29:fa:e8:83

  Note the different MAC addresses.

  Digging a little further I discovered that Windows 2003 server has configured on "Local 1 network connection" network load balancing and NLB is the cause of the altered MAC address.

  Rather than to investigate further I have just placed a load balancer linux before the server windows 2003 cluster and that you turn off NLB.

  But I suspect that there is still a fundamental problem in the Virtual Switch VMware with how he learns the MAC addresses of the virtual machine is using flexible vNIC. In particular, with a virtual machine that uses a form to override the MAC address such as that used by NLB.

• Two NETWORK adapters on the host

  I have a windows xp host and he has two NICs. One is used to connect to the internet, and the other is used to connect to a private network of Novell.

  What is the best way to configure my VM Windowx98SE so that it can use both of these connections?

  If I have a single configuration network adapter on my VM and use NAT, I can connect to the internet, but not of Novell.

  If I have a single configuration network adapter on my VM and use Bridged, I can connect to my Novell network, but not internet.

  If I place two network cards on the VM and the whole NAT and the other to connected by a bridge, I can connect to Novell, but not internet.

  Any ideas?

  Thank you

  Josh

  Well, it turns out that the adapter "set" parameter is Global not by NIC so you must briing the real Publisher virtual network and create a second bridged VMnet, say VMnet2 and then jumpered VMnet0 and VMnet 2 to different network card.  Then caraa change the second NETWORK card in the .vmc configuration file to account for the bridged custom VMnet2.

  ethernet1.connectionType = "custom"
  ethernet1.vnet =  "vmnet2"
  

  To display the real virtual network editor in VMware Player 5 in an administrator command prompt, change the directory for VMware Player and use the following command.

• Failed to create FT logging with grouping of NETWORK cards

  I use vSphere vCenter 5.1 and 5.1.

  I create a port group of kernel VM on a new vSwitch, assign two NICs used on my ESX Server and logging FT. I have then add a second port VM kernel group to the two network cards and also assign FT logging. When I do this FT Logging the first port of kernel VM group is disabled. If I then manually enable FT gones then a second by logging on the first group of ports of kernel VM mode off.

  The same thing happens when I create 2 vSwitches, assign 1 NIC to each of them and assign the FT logging.

  I wanted to create my FT Logging predisposees in this way to match what I've done with vMotion and VM Network.

  I do something wrong or you can have a group of ports per server for recording of FT? Please notify.

  Thank you

  Multi-NIC VMotion is a new feature in vSphere 5.0. Multi-NIC FT has not yet been introduced. You mentioned trade Multi-NIC VM, but it is not possible either. While you can have two interchanges to connect to the same VLAN they must have unique names and a VM NIC may connect only to a unique name.

  What advantage do you hope to achieve with Multi - NIC FT? If the goal is more throughput 10G is the only option currently. If the lens is better traffic load balancing so that you could watch LACP on the vDS.

• The networking redudancy, 2 network cards, active/active or active / standby?

  I have two network cards available for my management network.   More 'design' documents that I saw an active set to NIC and the other in standby mode.  What is the advantage of this approach compared to their definition both active?  Suppose I have no limitation of NIC and these 2 ports are dedicated to management only.

  If you have no other exchanges on this vSwitch then you can leave them as an asset with no problems.

  Sometimes, the VMK vMotion interface is placed on the same vSwitch as VMK and if yes, it is good to separate them for different vmnic with active / standby.
