• Problems with the MAC address duplicate when creating new jobs virtual

  We use the MAC addresses of vWorkspace management. This means that we have the option set as an attachment with the basic MAC address pic01. This has worked well so far. We now extend our VDI environment with the new Virtual Machines in a new group. But now, we got the question if we create a new desktop computers, the broker for connections will distribute double MAC addresses (see the pic02 attachment). And as you know it will end in a messy DHCP and TCP/IP. Even if we put the basic MAC address to a new range, the broker for connections always distributes the old MAC address range. We restart the broker for connections rather than on the time and the problem is still the same!

  Does anyone have ideas or solutions to this problem?

  If you need additional information just let me know.

  Versions:

  vWorkspace Broker for 7.6.305.845 connections

  Client tools PN 7.6.0.820 (former VM) or 7.6.0.845 (new VM)

  Hello

  Address management Mac is for groups of clouds. With groups of clouds, the machines get deleted/re-created very often so we need mac address management to allow the mac address be reused after a certain period of time.

  With traditional groups, the machines are kept for long periods of time if you don't use mac addresses that you will get the number you have described management.

  Thank you, Andrew.

• I can not send e-mails through with the ip address that I have now, it's an address.now of earthlink I have more earthlink, I need to change so it will send to someone, please help.

  I can't send all e-mail messages through the ip address that I have now, which is earthlink.  I need to change so that I am able to send messages to anyone.  I have windows xp - outlook express.

  If you no longer have the earthlink address, then you need to get a new email address before establishing an account.  You cannot configure an e-mail account by using an IP address.  Your internet provider or someone else must provide a first e-mail account.

  In OE, you can then go to tools | Accounts | Add | By post, then add your new email account in OE, so it can get messages.

• Determining the MAC address generated by VMX

  How the MAC addresses are generated when a new virtual machine is created/cloned using ESX and especially LabManager?

  Is the set of predictable, algorithmic MACs potential, or is it completely random?

  The use case, is that I need to know all of the potentially valid MACs which can be assigned to any given virtual computer.   It is calculated from the CMA of the physical host?  Is it still a finite set?

  Any idea is appreciated.  Thank you

  Generated by the Lab Manager MAC address will be in the following format:

  00:50:56:XX:NN:NN

  Where XX is the installation ID of your Lab Manager you will find on the General Settings page. Remember that you must convert to the spell. Example, if your installation ID is 41, so all your MAC address will look like 00:50:56:29:NN:NN.

  NN:nn is the unique number assigned to the network adapter. each virtual computer

  So let's say that I log in the laboratory Manager (whose installation ID is 41) and create a virtual machine with two network cards. It can assign these MAC addresses to my two network adapters:

  00:50:56:29:00:60

  00:50:56:29:00:61

  Now say I have add a new network adapter. The MAC address assigned to the third NIC will be 00:50:56:29:00:62.

  Now let's say I delete the first NETWORK card MAC address is 00:50:56:29:00:60. Then I go and add a new network adapter. MAC address will be 00:50:56:29:00:63. The MAC address that was previously removed won't get recycled, at least not immediately.

  In order to predict the MAC address is doable as long as you are aware of all MAC addresses in use on your system.

• WGA600N and change the MAC addresses wireless! Grrr!

  The exec summary: why in fire the wireless MAC address changes with each power cycle? It can be stopped?

  The rest of the story: just got my adapter and had problems he connect my Linksys WRT110. Discovered the hard way that the MAC address on the label is the * wired * address, not the wireless MAC address. Has been able to configure the adapter and use the admin software to watch the Mac wireless. I plugged this address into my WRT110 that has the MAC address filtering turned on. Smart card, life was good.

  Unplug the adapter and it moved to its final location. Plugged in, no connection. Received a computer laptop and connected to the card, and this amazed my eyes see but the wireless MAC address has changed with the power cycle! Unplugged the card even once, waited a few minutes, then plugged in. The wireless MAC address verified again and of course, once again changed.  When did it become an acceptable practice?

  It is of course difficult to use the card in an environment with MAC address filtering turned on. Is it possible to prevent this address change?

  Thank you

  Found the answer - the wireless adapter takes the MAC address of the device, it is well plugged. Interesting.

• Why is the MAC address Clone?

  When I disabled it Clone MAC address I lost access to the internet.

  Does anyone know why MAC address Clone is necessary and what it does?

  Clone MAC address changes the MAC address of the router on the internet port.

  You can use the function of the cloning MAC address to clone the MAC address of a computer if you used before your computer directly to the modem.

  Some ISPS (especially cable ISPS) only the customers to have an active internet connection at any time. To do this, check the MAC address, that is, they remember the MAC address that accessible line via the modem and lock the connection to this MAC address.

  If you test your internet connection directly with your PC first and then connect the router the router can not get an internet connection because the row is locked to the PC's MAC address. Now if clone you the address MAC from the PC on the router the router "pretended" to be PC and the ISP will accept traffic again.

  Usually, simply reset or turn on the modem to reset the lock again. Sometimes, you have to turn off the modem for a couple of hours (for example, through the night) after a few hours of inactivity the ISP removes the lock again. Sometimes call the ISP to remove the lock, but it's not very often.

  So basically, generally useless clone MAC address at all because you could accomplish the same thing by resetting the modem or it turned off for a few minutes. If you connect the router to the modem, ISP learns the MAC address of the router and it gets working internet connection. (Of course remember, that once a computer directly connected to the modem would not get active internet connection unless you change the MAC address of the computer to the MAC address of the router).

  But the function is useful if you do not want to. You simply set the MAC address of the connected device before, and you get a working internet connection.

• VMware device with 2 network cards claiming the same IP address with two MAC addresses

  Hello.

  I see messages intermittent my gateway network two MAC addresses associated with a virtual machine running on a 5.5 ESXi host for the same IP address.

  The virtual machine is a MiTel 3300 controller for a VOIP system. the system is configured with two IP addresses, one on the local network and another with a public IP address in the DMZ. In the network configuration of the 3300, I assigned the address LAN IP at 00: 0C: 29:30:B2:B2 and the DMZ IP at 00: 0C: 29:30:B2:BC (Mac for network devices presented by the ESXi host virtual machine).

  On the host, I configured a vSwitch with exclusive access to two physical network adapters on the host machine. The vSwitch is configured with two machine virtual port groups, LAN and DMZ, with access to the physical network interface cards. Tab grouping of groups vSwitch port NIC, I replaced the order of failover of the switch to activate an active NETWORK card only for the Group of LAN ports and the other card NETWORK only for the DMZ port group. (I don't know how the content of the column of networks is determined. Neither is correct for the traffic on the physical switch. If these are configurable, please advise and I'll change the settings). The relevant parameters of vSwitch, groups of ports and VM are distinguished below.

  On the virtual machine itself, through the VMWare host, I assigned 00: 0C: 29:30:B2:B2 for the Group of LAN ports and 00: 0C: 29:30:B2:BC to the DMZ group port (best I can tell, anyway, since the MAC address field annoyingly obscures the last two digits of the MAC address - break if I invert the mapping) (, but all seems OK).

  The goal here is to make sure that MACs of ports vSwitch the 3300 is listening and sending always correspond to the physical ports that are VLAN Tag by the physical switch to ensure the routing. Generally speaking, it seems that what is happening but, intermittently, we cross one-way calls that suggests a problem of routing between us and our SIP trunk provider; coinciding with these incidents, I get an email along the lines of "the security in the network device has detected a conflict of IP address with two or more devices. The period of INVESTIGATION "DMZ. DMZ. DMZ. DMZ' is claimed by the following clients with MAC addresses: ' 00: 0C: 29:30:B2:B2' ' 00: 0C: 29:30:B2:BC'. »

  I did something in the configuration that would lead to this kind of collision intermittent? Have a hacked together a way to do something that could be accomplished in a way that is simpler and more reliable?

  Thanks for any idea that you can offer.

  Kind regards

  J.

  

  

  

  I probably don't fully understand your configuration, but it seems that you are not interested in using the collection of NETWORK adapters in the virtual switch of the VM MiTel 3300.

  If it is correct, why not create two virtual switches, each with a group of port (LAN and DMZ) unique and with a separate connection of (vmnic2 and vmnic1)?

  In general, collection of NETWORK adapters may be used to share traffic between uplinks and ensure that if one of the uplinks connect fails, a virtual machine still has access to the network.

• How to change the local IP on the virtual NETWORK adapter for Web server address

  Hi all

  I have a physical Windows system, on which I run VMware Workstation 9. Now on VMware I run Ubuntu 12.10 a LAMP for a Web server.
  Problem:
  Now, my local IP address for my NETWORK card virtual (using the Ubuntu one) at the address 192.168.159.7 and my router only emits the 10.0.0.x range IP addresses. So if I want to port forward to the virtual NETWORK adapter that has a 192.168 address, I can't, so my LAMP Web server are not accessible to the outside because the router does not send packets on port 80 to the virtual card... How to fix this?
  The only way I guess that is to be assigned an ip address of 10.0.0.x to the virtual NETWORK adapter?
  But how do I do this?
  I tried to do it on the host from the Windows machine with "get my IP address automatically", but she emits an 192.168 address every time...
  Thank you

  Welcome to the community,

  I guess that the virtual computer is currently configured to "NAT" or "Host-Only' networking! That would explain the 192.168.x.x IP address.

  There are 2 options to be able to access the web server on the virtual computer.

  1. with "NAT" network configured

  In this case forward port 80 to the IP address of the host and configure the port forwarding on the virtual computer in the "Virtual Network Editor. This way you can leave the IP address on the private network of 192 (if it is currently set to NAT)

  2. use "Bridged" network layout

  Reconfigure the virtual NETWORK adapter to the machine virtual networking "Bridged" within the parameters of the virtual machine, assign an IP address from your router network (10.x.x.x) and do the port forwarding on the router directly to the IP address of the virtual machine.

  Have you checked the TCP/IP protocol settings?
  Do this!

  The settings are located in:
  Network connections-> network connection WLan-> properties-> Protocol TCP/IP-> properties

  There you have to make sure that settings such as; obtain an IP address automatically, get the DNS should automatically be marked!

• Analyze the Mac address with the regular expression matching

  Hello world

  I have a problem with the function of regular expression matching,

  I try to analyse the response both a query arp - a 192.168.0.15 to retrieve the MAC address of the remote IP address, I used the following regular expression: ^ ([0-9a-fA-F]{2}[:-]){5}([0-9a-fA-F]{2})$

  I wonder why should I do a subset of the first string to extract only the part of the MAC address. The regular Expression function is not able to recognize the regular expression directly in the middle of a string?

  I only works when I extracted the subset of tring right as in the picture below.

  Thanks for your replies.

  Get rid of the "^" at the beginning of your regular expression. You are ordering him to find the model at the beginning of the string.
