configure multiple NICs

Similar Questions

• Multiple NICs

  I have a user who has multiple NICs on their machine. Sometimes remote-scan checks the correct network card, sometimes it isn't. Is there a way to lock Remote-Scan to the network adapter that is saved?

  Default remotescan remembers the network adapter selected when it fires. Sometimes remotescan may fireup before that all network cards are online or initialized. There is a directive to say remotescan ini setting delay start giving so I hope that sufficient time for these cards to come. Or if you have any startup scripts, simply put remotescan to the end, etc.

  If, for some reason, this card has been disabled remotescan grab just the following in the list. The next time remotescan pulls up, since this new adapter is the last selected, he remembers that one.

• Tolerance of failure with multiple NICs

  Apologize if this has been asked before.

  I'll put up a vSphere 5.5 environment and I have NIC 1 GB for each host to devote two NICs per host for tolerance to failures.  I was wondering the best way to set this up to their maximum output.  I have implemented as a Multi - NIC Vmotion?  As noted here: VMware KB: Multiple-NIC in vSphere vMotion 5. Essentially using two groups of ports as FT-1 and FT-2.  Or what I need to do as a Multi-NIC iSCSI with separate vswitches and each vswitch with a Port Group.

  Thanks in advance.

  You run into a problem of flow when you use 1 NIC for FT?

  Currently FT only supports using a single network adapter (1 G or 10 G)

• How to configure multiple clusters on the same machine.

  I'm trying to configure multiple clusters on the same set of machines. I put the name of the cluster and multiple cases IP addresses different for each cluster. However I am still in train and error stating:
  "This indicates that there are multiple clusters on this network, try to use network configurations that overlap.
  
  Isn't this possible? If it is possible, is it still possible that I need to tell the virtual machines that they belong to different groups?
  
  Thank you
  Jacob

  I put these lines in my script for starting a prod. For dev I REM out as below.

  REM set java_opts = % java_opts %-Dtangosol.coherence.clusteraddress=224.0.0.1
  REM set java_opts = % java_opts %-Dtangosol.coherence.clusterport=65432

• Multiple NICs configuration

  Please guys, I could really use some help.  Even after RTFM, I felt how much a noob in fifteen years.

  I had a COMPUTER technician long lost preach the wonders of virtualization for me and I saw the light.  So 2 years later, I'm ready to give it a try on my first production server.  I did a few tracks of practice developing successfully, but I can't reproduce exactly what I feel when I do in production. Specifically associate network.

  I am to convert a VM supported Dell PowerEdge T620 from physical to virtual.  Right now the physical server has a production Oracle database.  It has 2 network cards physical, 1 connected directly to the internet and connected to the internal LAN 1. I use VMConverter and empty the contents of the server to another machine, install VM ESXi 5.1 on the server, and empty the contents of the original server in a newly created virtual machine.  I then created a second VM for use as a file server.  I tested on a separate machine with no problems EXCEPT that... the network settings.  What the hell I do?

  I think (scary) that I need is 1 physical NIC w / 3 internal IP (192.168.0.28 - Oracle, now VM1 original INVESTIGATION period), (192.168.0.29 - new fileserver VM2), (192.168.0.30 - virtual computer management).  The other physical NETWORK adapter should have just the Internet (24.23.x.x) IP address and will be available at VM1 since only the Oracle DB must accessible via the internet.

  Is this sound right and how Devil can I configure it?  I went through the Guides of the network, but I am more confused than ever with groups, ports, distributed switches, standard switches, etc.  Do I still need to go down this path?  My head hurts.

  Thanks for any help.  It's really appreciated.

  Wile E. Coyote - Super Genius

  All network adapters must be attributed to a vSwitch, even if used by only a single virtual machine.

  In your case, you want to do this:

  NIC1--> vSwitch 1-> 1-> NIC on Oracle VM PortGroup (this virtual NETWORK adapter has the IP 24.x)

  Map NETWORK 2-> vSwitch 2-> 2-> NIC on Oracle VM PortGroup (this virtual NETWORK adapter is 192.168.0.x address

  -> NIC on other VM (this virtual NETWORK adapter will have address 192.168.0.x)

  -> vmkernel port (for management - new 192.168.0.x)

  Hope this helps.

• Increase throughput for iSCSI with multiple NICs

  I'm implementing a new host ESXi 6 using a Synology NAS as an iSCSI target. I have 4 nic of the Synology stuck in 1 connection, so it has 4 GB of throughput. So far, over my hosting provider, I have two nic I dedicated to iSCSI traffic. So far, I put vSwitch under 1 two NICs and I was playing with patterns. I put two 1 vmkernel network cards and set as active adapters. However when I watch the iSCSI network traffic I only see traffic on a network adapter. This of course caps my speed to 1 GB. I would like to be able to bind several network cards so I can get a flow more. I tried changing the selection of the path for the warehouses of data in Round Robin are therefore at least two active nic. But which always leaves me with two individual connections of 1 GB instead of 2 GB connection. Is it possible for me to get there or I'm better off just having several 1 GB NIC load balanced?

  I'm not familiar with the Synology. However, what is generally - in the case where the storage system supports - is to set up several uplinks on the side of the target of storage/as well as on the initiator/ESXi side, each with their own IP address. Once configured, you can use multiple paths to access the target. According to the capabilities of the target, Round-Robin (if supported) will send traffic through all the links, i.e. using the bandwidth of all the links.

• vMotion on ESXi5 is not using multiple NIC

  Hello

  I test 4 x simultaneous vMotion operations on the host ESXi5, and "thought" he was supposed to distribute the load between the two NICS in a config.  resxtop shows that he always uses one NIC someone can provide an overview?

  100663298 vmnic2 - vSwitch3 4216,66 1946.27 16672,65 8.40 0.00 0.00

• Configure 2 NICs for a virtual machine

  Hello

  How can I connect two physical network interface cards in a virtual machine?

  Each NIC is configured on a separate network - but on the same machine.

  is it possible...

  Thank you

  Hello

  Just create 2 vSwitches on the host, allocate the host's physical network cards to the separate vSwitches, then create the Group of ports by vSwitch, in the comments adds another nic and assign it to the Group of ports that you need.

• Configuration of NIC in the cloned VM

  With the help of Workstation 8.0.1 build-528992, I created a basic Linux 6.2 CentOS VM guest in network bridge. This setting is configured as my model VM I use to create virtual machines other, specialized.

  I then cloned this virtual machine as a full clone, without link. Before you start the virtual machine, I clicked on the network card. Advanced... button and generated a new MAC address.

  After starting the virtual machine cloned, I ran ifconfig and got this:

  eth2 encap HWaddr 00:50:56:26:0 A Link: 3F
  INET addr:192.168.2.118 Bcast:192.168.2.255 mask: 255.255.255.0

  collisions: 0 txqueuelen:1000
  RX bytes: 1548 (1.5 KiB) TX bytes: 1548 (1.5 KiB)

  The eth2 listen to me, so run this: ls/etc/sysconfig/networking/devices. He told me that I have a NETWORK card device, ifcfg-eth0.

  Then, I ran system-config-network and chose the Configuration of the device. Again, it has reported only eth0 was available.

  Recalling that I saw before eth2, I thought that perhaps that eth0 has not been started. So I issued a command ifconfig eth0 up . It reported unknown interface: no such device.

  So my questions are:

  (1) where did he eth2?

  (2) where eth0 is?

  (3) how can I fix this so that the one and only one NIC is eth0?

  Thank you.

  It is in fact the re-creation of the MAC address, which is regarded as a new NETWORK card, and therefore a new interface.

  You can either edit the file and remove the external devices, or you should also be able to remove this file completely (to move somewhere else to play it safe) and restart.

• Configuration of NIC for ESXi 4.1

  Happy to wander what others do for their NETWORK card for ESXi 4.1 configuration I want to use the following:

  pNIC0-> vSwitch0-> Portgroup0 (management)

  pNIC1-> vSwitch0-> Portgroup1 (VMotion)

  pNIC2-> vSwitch1-> Portgroup2 (the VM network)

  pNIC3-> vSwitch1-> Portgroup2 (the VM network)

  pNIC4-> vSwitch2-> Portgroup3 (DMZ network)

  pNIC5-> vSwitch2-> Portgroup3 (DMZ network)

  I don't have that much wandering DMZ traffic so if I should use one of the DMZ NIC for VMotion or management.

  Mike

  According to me, it looks good, you have redundancy built in.  The only thing that we do, and maybe you do the same thing is on our vSwitch0 active/standby network interface cards to each other.  The other vSwitches are set to active/active.

• Best use of multiple NICS (collaborate with VIRTUAL networks or physcially separated)

  Set up my new production environment vSphere and trying to figure out the best way to set up the network.  I have pictures to illustrate, but the basic question is:

  1. use all NICS in a pool and VLANS to separate traffic - or -

  2 devote some physical nic to only certain things (VMotion, FT etc..)

  We use Dell R710 2 servers with 6 NIC of each.

  Our SAN is connected via zFCP iSCSI, see you in the group is therefore only for failover of emergency if environmental FC had to leave for some reason any.

  Please let me know which design you think would be the best.

  Thank you

  Hello

  Everyone says to separate the service of the VMnetwork console.  If I can separate the traffic of service with one console vlan why separate physically?  If something happens to the service console connection disconnects but my machines always communicate then I would have trouble.  Why not make sure that if the network paths are for machines that I can control the server VM?

  Your VMNetwork is one of network environments more hostile within the vNetwork as its arbitrariness and a point of attack if someone breaks into a virtual machine. If you have the virtualization management network attached to your VMNetwork is on, there is a VERY good chance that the pirate VM now will be used to launch an attack against the network of virtualization management. Given the current set of attacks there is a VERY good chance of success. For security reasons, you want your management network virtualization to be separated and protected by a firewall of any other physical and virtual network. Ideally on its own switches with output physical switch VLAN in use. However if you use VLAN physical switch then you put your trust in these spending patterns, so you want to increase your monitoring of these switches.

  Since the original post, I combined the iSCSI traffic because it is a failover of emergency only where my zFCP hardware has a problem.  The iSCSI link rarely go to never get used and I didn't spend 2 physical network cards to something that would almost never be used.

  You want to spend 2 links for iSCSI, if you still do not have a failover, you can the bandwidth and redundancy. Consider all the links of storage redundancy.

  Let me know what you think on the service console.

  When you use VLANS in the vNetwork you are automatically protected against most known layer 2 attacks, but in the pNetwork you are confident that your switch configurations you will protect. These configurations have been known to change and not necessarily for the better. Some say, it must break so for that to happen, but 1 problem of configuration and your SC is now attacked. Remember, once the virtualization management networks can be attacked they can probably be broken. I know a pen-Tester, which can do that in a very short time, and they will have your virtual environment.

  Protect the machine from service/management console, Client vSphere, vCenter servers as if they were gold, access to them implies access to almost everything. That's why VMware strongly recommends that you create another network of virtualization management a firewall of all systems on your system. That within this firewall that place you jump machines that run all vSphere SDK and vSphere client and that you use something like RDP to access these tools without their execution through your firewall. Make this thing increases the security of your global virtual environment of giant protecting your investment in the current batch of management network attacks. VLANs are not a security tool, they are a tool of separation of network based on the pNetwork is correctly configured, maintained and checked. VLAN security is based on the confidence in your pSwitches not something that is authoritative.

• How to configure multiple instances in CF9

  I'm having some problems with a couple of our intermediate servers that run multiple instances of CF9, and I do not know if they are properly configured. I have installed CF9 Enterprise multiserver and I created 4 additional instances by using the Instance Manager. I also created a virtual machine for each of them to use specific Java and re-recorded each service in order to use the custom Java virtual machine. In Apache, I added the following for each virtual server (by changing the serverstore and the port):

  < IfModule mod_jrun22.c >

  JRunConfig Serverstore "C:/JRun4/lib/wsconfig/muffin/jrunserver.store".

  JRunConfig Bootstrap 127.0.0.1:51000

  < / IfModule >

  However, when the service is stopped for one of the sites, rather than get the JRun error 500 but it will return a CF error or the site will still ride. But if I stop the backend CF service he will kill all the sites.

  It seems therefore that all instances are still tied to the main service. Y at - it something that has not been configured correctly or something I'm missing here?

  I used this guide during the installation in place all the http://help.Adobe.com/en_US/ColdFusion/9.0/Admin/WSc3ff6d0ea77859461172e0811cbf364104-7fc4 .html

  Thanks for any help.

  Most of the time, everything seems as it should work.

  My jrunserver.store files all say the same thing as yours.

  Did you do a restart on Apache and CF just to make sure things are picked up correctly?

  A number of things you can try, but I don't know if it will make a difference or not.

  In each of your virtual servers, remove the

  JRunConfig Verbose true

  JRunConfig Serverstore "C:/JRun4/lib/wsconfig/2/jrunserver.store".

  JRunConfig Bootstrap 127.0.0.1:51000

  And just do:

  JRunConfig Verbose true

  JRunConfig Serverstore "C:/JRun4/lib/wsconfig/2/jrunserver.store".

  JRunConfig Bootstrap 127.0.0.1:51000

  Also add in "JRunConfig Apialloc false" to each of them. This will allow the stub to take memory from the operating system instead of Apache which is supposed to be safer.

  Let me know if any of these help not at all.

• Configure multiple HTTP servers with APEX SSO

  Hello
  We currently have APEX configured to work with SINGLE sign-on using the URL http://server.com:7777/pls/apps. Some companies prevent users to go to the URL with the port 7777. We set up a new server http https rather than just current http implementation. All applications that use the SSO do not work with the new URL. I've added the new partner application in the SSO admin and tried running @regapp.sql. APEX may be configured to run multiple servers http with APEX engine registered as a partner app? We are finally going to a single server but need both up during the transition period. Thanks for any help.

  Brian,

  Yes. As long as the value of lsnr_token inserted by regapp is unique. It looks like HTML_DB:hostname:port.

• EA2700 - how to configure multiple ports

  The EA2700 is a router 4 ports (Ethernet) + WiFi.

  I want to configure the port forwarding, but the configuration screens won't let me set up several ports.

  It allows only an IP address to a transmitting device.

  I have an iMac and a Mac-mini two ethernet connected and a random collection of iPad/iPhone/printer, etc. WiFi devices.

  The Mac mini is a web server and is visible on the outside, but not to the iMac.

  The iMac can partially accessible by using the ip address of the mini (192.168.x.x), but while it displays the text on the page, none of the pictures show.

  I'm converting a Comcast Technicholor-modem/router WiFi to a surfboard 150 + LinksysEA2700.

  As far as I know, working directly from the iMac all connectivity works as expected, except for the mini.

  IF I disable the port forwarding, contact attempts are simply the prsented with the login to the EA2700 page.

  Normally you can not forward the same port of two different IP addresses.
