Probably stupid question of networking

Alright, I've been beating my head on this fairly long and searching through all of the documents that I can find has not helped.  In fact, I installed vSphere 5.5 on a new Dell server with two connected physical network interface cards.  Using the default vSwitch0 which has been configured, I added two virtual machines to the Group of network port of the virtual computer with one of the physical network adapters.  The problem I encounter is that whenever I start up a virtual computer, it connects to the network very well.  The second machine, however, can't connect to the network.  I have:

Tried various combinations of DHCP/Static IPs

Restart networking on both machines (one Ubuntu Linux, the other server Windows 2012)

* Disabling/renabling tried the options 'Connected' in changing the settings

* Tried to create a group of separate ports for each virtual machine

* Tried to create a separate switch

Tried another Windows 2008 virtual machine

The behavior is always the same.  If I assign static IP addresses and the ping between the machines, they can both see each other, but the other has begun can not see the network.

I know that the answer must be stupid, or someone else would have asked it already and I have found out there somewhere in the Google-land...

Thanks in advance!

Welcome to the community,

What type/model of physical switch are you using? Some switches come with port security, which generally limits the number of MAC addresses on a single physical port to two.

  • Probably stupid question, but - how to remove a clip of movement tracking?

    I was playing with the functionality of tracking movement and think that I can come up with a way to do the work to highlight my now famous 'football '.

    However, I need to remove the effect (s) that I added to the clip so that I can start fresh motion tracking.  For the life of me I can't understand how to remove!

    This can be a very basic question - and I'm sorry, but I can't find the answer.  I can not just delete the original yellow followed - boxes

    Thank you in advance for your help!

    Kim

    To remove the Tracking Motion, just delete the chart you attached to it. There is no need to remove the object itself.

    But you can if you wish. Just click to select the item and then click the motion tracking tool. Right-click on the blue or yellow squares, and then select Delete.

  • Digital networks... Maybe a stupid Question

    I have three updated servers in place currently in my lab. One is 3.3.4 Call Manager called EV. I have two other servers, the two 4.0.3/EX2000 unity. One is called AA and the other is called EVVOIP which is connected to the EV Call Manager. Two unity servers are in the same domain/AD Forest, but different Exchange servers. I configured the search options, options for addressing etc.. I have also configured a dial in EVVOIP area, and there have been replicated to AA, so I could select it. I did the reg also hack. When I use a telephone connected to the CM and go in the EVVOIP unit, I hit the ' * ' key to access the main menu. I select '4' to join the fate of directory name. I can get the names of the local server on EVVOIP, but when I try to retrieve the names of AA, it returns nothing.

    Here is the stupid question. Do I need to have an another call manager to the top and connected also to the AA unity server running? I'm not trying to transfer a call, just try to search for names. I can't join the names from the store of the AA unit.

    Thank you.

    Yes, it is certainly a factor.

    The choice of name list manager will never offer a username to a caller outside that does not have a name of the recorded voice. For subscribers addressing messages, these users are, of course, available, but they are checked with their extension number (no doubt if an external caller knew their extension number they would have composed it).

    If you need to record the names of a few votes for users before they will appear in the list manager of choice of name for external callers.

  • REALLY stupid question about virtual machines and disks of cancellations.

    I'm a bit hesitant to ask this question because it might make me look stupid, but...

    When I'm done using Virtual PC and a virtual machine running Windows XP Pro with Vista 64 Home Premium because the host os, often I did not any significant changes to the hard disk of the virtual machine.

    What I save gets saved to a network share on my server for files and printing from Win98 and saved on a flash drive.

    Assuming that I do no configuration changes or anything else I want to keep, is there a reason barely stopping properly when I 'cancellations discs' enabled?

    Any reason, I can not save time by pressing the 'X' button and choose 'disable and remove changes '?

    I am aware of patches, but took me to inform me of the patches, and I can get patches when it's convenient for me and I always validate changes when I install the patches. I'm not using it for anything other than my classes of the school of the evening for the time being, so it is not much of a value of protection on the virtual machine, and I used to write papers on the host operating system. I just use the virtual machine to play with the admin tools in an environment where I can easily fix it a massive screw-up without spending hours to reinstall Windows.

    Hey SlickRCBD,.

    Not a stupid question at all! :)

    It's very well hit the X when you have activated the disks of cancellations. And corruption or problems with the active virtual machine will be resolved when using the drive to cancel it.

  • BlackBerry Smartphones has BB for less than 24 hours... some (stupid) questions!

    Hi all

    I looked through some tips and read the summary instructions (at best) that came with my BB and now have a few questions, if that's ok:

    1. I downloaded the "favorite" of Facebook, but I don't know where that is?  I thought this would be an icon, I could then add to the home screen?  If it IS, then how can I find and to do this?

    2. is it possible to add my iTunes Catalog, or a part of it, to my BB - are compatible somehow?

    3. how to choose something other than the horrible Vodafone home page, to be my homepage on the internet?

    5. What is the difference between "browser" icon and the icon "WAP"?  Am I meant to go through one preference to another, because in the end, they both make the same thing?

    6 represents the number of pins only to give BB 'friends', so we can chat on messenger, or there are homonyms?

    Again, sorry for the stupid question; I'm really proud of the implementation so far without any help from the husband, but having my llimitations, lol - it's a world apart form the Nokias I've owned exclusively for the past 13 years... but I think I love her!

    Thank you

    1. I don't know about a 'bookmark', unless you try to bookmark a place in your web browser? You can download and install the Facebook for BlackBerry application.

    Use the browser of your BlackBerry to access www.blackberry.com/facebook

    2. Yes, use of BlackBerry MediaSync software...

    http://NA.BlackBerry.com/eng/services/media/mediasync.jsp

    iTunes with DRM will not transfer, DRM coding should be removed first of all files.

    3. open the browser to the page that you are going to choose as your home page, and then press the Menu key > Options > browser Configuration > scroll down > address Home Page > use current Page

    5. I would like to use the browser icon. WAP icon uses the data of your service provider's WAP service.

    6. the PIN identifies your device to the network and is, so to speak, "Digital ID" in your devide.

    And Yes, your use of the primary AXIS will invite friends with BlackBerrys chatter on BBMessenger.

    You would benefit from reading and practice of 9700 (very similar) my friend Mr. Stinsonddog PIL.
    Look at this link for them, download and print the PDF file and practice the tips using your device. You will be amazed at all the cool things that your BlackBerry can do.

  • Stupid question? S/W antivirus on Host and Guest machines?

    Hi people,

    Maybe it's a stupid question and a really easy question to answer, but I have anitvirus software installed on my host machine and my computer invited? (One of each). Or could this posslibly causes some kind of conflict or slow down my whole system accordingly.

    Just to clarify my guest computer resides on the C: drive of my host computer and both are running windows 7.

    Thanks in advance.

    Carlo.

    Any system, physical or virtual, must have security measures in place.   Installing anti-virus on any system, physical or virtual, software affect performance to some extent and do it by running on the host and the compounds of comments however any system that has a network/Internet connectivity is in peril and the host does not necessarily protect comments or vice verse.

  • Add more memory for hp nc4200 - stupid question

    I know it's probably a stupid question, but I'm trying to insert more memory into my old laptop for my son. The vehicle currently has 1 GB of memory that I see when I take off the lid, but there apparently also 512 MB that I can't see. I thought of taking the 512 MB and replace it with a stick of 1 GB giving my son of 2GB, but I'm sitting here, after removing the cover and although I can see where is the 1 GB, I see no sign of the 512. Are the memory sticks in two places, not one, and if it's a how to insert the 1 GB when there is not enough space?

    DDR II SDRAM, 400 or 533 MHz, two locations SODIMM, 256/512/1024 MB expandable to 2048 MB maximum

    Here is a link to the welcome and maintenance guide.

    It is an internal memory and an external memory module. Replace the external module is quite simple. Access to the internal memory card requires a dismantling. See page 6-28 in the manual.

  • Stupid question * EVER *!

    I admit, he is a stupid question that probably answered a million times. But I have not found the answer. I have video clips that I want to put them on DVD and I would like Premiere Elements automatically locate the individual clips and make a menu. Is this possible? Otherwise, what is the best way to achieve this?

    Thank you!

    As I understand it, it's basically how pre works with DVD authoring (the process of making Menus and navigation for a DVD).

    What you need to do, and you probably already know this, but go on, just in case, are to import your Clips into a project. The project must match your Clips source 100%.

    Do drag each item to the timeline and modify, as necessary.

    When you are finished, choose the Menu set (contains the main Menu and scene selection Menu), and then set your Menu marks and your chapter markers.

    Preview.

    Burn to record, or burn to disc. Pre will connect repel your chapters (these values are set but you want) to the chapters in the scene selection Menu, and you're done.

    Hope that helps and is what you're asking. Good luck

  • stupid question for a smart programmer

    This is probably a stupid question, who need a simple answer:

    I'm looking to the 'length' property in the Adobe AS3.0 language ref as I don't understand.

    It is said:

    An integer specifying the number of characters in the specified String object. (I understand it)

    Because all string indexes are zero-based, the index of the last character for any string x is x. length - 1. (I don't understand the '-1 '.) I understand that all string indexes are zero, but I can't put it as well as the last character for any string said TI-1 or something.

    Do you understand this and can you help me understand?

    Thanks in advance.

    If you create a simple example, you should be able to see for yourself.

    The length of a string is the number of characters in it.

    The index values for string to start at zero.

    So if you have four characters in a string, say "0123" is the string, then its length is 4, and because indices start at 0, the index of the 4th/last character is 3 (length - 1).

  • Stupid question about compatibility

    I would be happy to search the forum for inDesign to discssions on compatibility with other editions, but it seems that it is impossible. Where this stupid question.

    Problem: a uniform translation ends me back-saved files in InDesign CS, which I created originally, but I can't open them.

    This that I have to spend $500 on an upgrade so I can open it or is there a way they can back - save it so I can open it?

    Thank you

    I think that I get it now. I doubt that the files have been saved as files InDesign CS. As I said before, it is impossible to back - save as InDesign files. Only InDesign X can save to a file, InDesign X. very probably, the provider is you open files in a later version of InDesign and save as native file of this version, InDesign 4, 5 or 6, you cannot open.

    You have three options:

    1. You are upgrading InDesign to be compatible with the version of the provider.
    2. Only translated text files, then you replace the text in your files.
    3. Having the export INX since InDesign 4 provider. If they use later to edit it can be a loss of hassle and risks of formatting.
  • Yes, that was a stupid question

    Yes. It was a stupid question. Serial number written on the bottom of the computor. Yes. I have it. DOH!

    Although it would be useful for Apple to include this info in the topic How to find section...?

    Still unresolved problem but it seems to be a non-accessible boot drive.

    Reserved it in for bypass surgery, so we're getting there.

    Apple has done an article on how to find a serial number:

  • Stupid question: why tinytots (and other similar fonts) will not work in Firefox?

    I am a user of Tumblr, if of course if I had to work on a theme, I would like to see the fonts that I have chosen to serve. In Chrome, everything seems as it should usually (relative to the fonts). In Firefox, I respond specifically to these two browsers so my theme seems not completely horrible. In my opinion, only a browsing experience more could be made if Firefox showed fonts such as tinytots for more than just me, but for someone else who is perhaps not brave enough to post about it. This brings me to another question: I'm just ranting or is it possible I can see these fonts and not know about it?

    This isn't a stupid question.

    Google Chrome has its own library of fonts.

    Mozilla Firefox runs Windows fonts library.

    To run on Firefox fonts, they must be installed on Windows and then Firefox must be restarted.

    Sometimes, Web sites do not use the correct font name and the police is found, even if it is installed.

    A good website designer would design a Web site with backup for users to load fonts if they do not have the installed font.

  • Stupid question, I know, but after years of use of Firefox, on this one I can not find the icon of reloading the Page? Help, please.

    In the past, when I refresh a page, I just went to page reload icon in the toolbar. On the new version, I can't have the icon charge. Sorry I know this is a very stupid question, but I can't find that reload icon. The toolbar is very different from previous versions, but I don't know tht pesky icon should be here somewhere!

    Firefox 4 and later versions use a combined Stop/Reload/Go button that is placed at the right end of the address bar.

    During the process of loading page it shows as a stop button and once the charging button is replaced by a reload button.

    If you type in the address bar this button would then become a button go.

    Click the Reload button to duplicate the current tab in a new tab.

  • stupid question about UAC

    OK, it's a REALLY stupid question about UAC.

    I have several icons on my desktop. Some of them are games that must be run as administrator in XP compatibility mode.

    I rarely accidentally tried to open the icon, particularly if you use the keyboard to choose what I want.

    Is there a reason if I accidentally open a game that pushes me in height DO NOT hit 'Cancel' if I didn't intend to play the game at the moment, but trying to open something else? Something like a process being left in suspense, memory leaks, or any other reason why I can't Abort to launch the application to the UAC prompt?

    Hey, Slick,

    Clicking Cancel will prevent the running total process if you do not have to worry about the still ongoing services for memory leaks or game, etc..
    I hope this helps.
