IOA FX2 constantly asking DHCP, exhausting vlan1 with BAD_ADDRESS

I have a Win 2008 R2 (and then upgraded to 2012 R2) DHCP server which is loads BAD_ADDRESS was complete the scope to the vlan1.  All other scopes for other VLANs are not affected.  Wireshark has indicated a mac address dell AIO management that the switch shown on our PortChannel3 (two interfaces 10gbe fiber optics).

But in our config IOA, we have a static set of the intellectual property of 10.1.0.103/16. The DHCP server is at 10.1.1.1/16 and also intellectual property offers in other scopes (10.2.1.1/16, 10.3.1.1/16, 10.4.1.1/16 and vlan5 10.5.1.1/16 vlan4 vlan3 vlan2).

I had to put the Dell AIO mac address in the DHCP deny list of filters and turn it on so that it would not respond and plug our full of BAD_ADDRESS address space.

No idea why the IOA is dhcp requests even if we put it to a static IP address?

Okay, I think I can find something.  On the config of switch, I am able to access by ssh to the MCC and issue a command to connect to the switch 1.

I see that he has this entry to see the race,

interface Vlan 1

DHCP IP address

MTU 2500

no downtime

So I conf t break-in

no ip address dhcp

Now I'm running wireshark and have not seen this mac address in my filter for bootp at all yet.  They may have been the problem.  What's weird, it's who knows why if it was on DHCP, that our server would not at all be because she a IP address and done with it.  Who knows why each minute the IOA kept DHCP and our server kept declining and then marking it a wrong address.

Anyway I don't have an ip address on vlan1 on the IOA because did not make any L3.  I also already have an IP address for the management ethernet 0/0, but I fail it anyway at his direct IP unless I port stop the e Gig chassis CMC management is well connected to our switch.  So I managed by ssh to the CMC and issuance of an order of connection.

The other AIO is on his own Brocade switch isolated with its own regime of intellectual property and all that is NOT connected to our LAN.  This brocade switch is simply a network storage IP for NFS on the VMS and our data backup appliance.

  • Java Applet constantly asked for authentication

    With having an application of ADF on Weblogic 10, with occasional access to a Java applet. The Java applet is loaded whenever this is necessary and not charge whenever it is not in a facet. The applet is currently in the folder public_html/applet.

    When we define the SSL configuration to require a client certificate when the Java applet loading, it will constantly ask a client certificate even if the user has already presented to the client by hitting the site:

    Identification of the required authentication request. Select the certificate to use for authentication.

    It's annoying for users and the Java Applet requires no authentication. Is it possible that we can disable authentication or remove the prompt?

    Here's the code included:

    <applet height="1" width="1" code="applet.Applet.class"archive="/app/applet/SApplet.jar" /><param name="permissions" value="all-permissions"/></applet>

    Things I've tried:

    (1) configure the Applet on HTTP instead of HTTPS; I get a warning about mixed content and still get authentication pop up.

    (2) created a small applet that only types "HELLO World" in the console, still get authentication pop up

    I try to activate the Fax Service. He keeps asking me: a CD with 'Windows Professional Service Pack 3 '. Of course, I don't have such a CD. When I try Microsoft doewnloading they tell me this service pack is 64-bit, but my computer is running 32-bit. Anyone has an idea how to get around this and activate my fax service?

    XP is expensive now, or maybe you can get a legal CD of a person. You won't have to reinstall you can move the license to your computer, and then install the fax from the CD. You will have also the CD incase never reinstall you or need something else of it.

  • In Vista, all files lost association, constantly asked what program to open a file with

    First of all, whenever I try to open certain files, such as Internet Explorer, paint, or whatever it is, I get the "choose the program you want to use to open this file", and it has not happened before. Along with this, the little thing bar in the lower right corner of the screen (which includes the Volume, time and everything) never ends load when I turn on the computer. I think I have a virus and spin the Virus Scan right now (AntiVir, to be precise, which I think will remove whatever it is detected). Two days ago pop-ups randomly came quite often, even when I'm not all Internet Windows running. It arrived yesterday and for the most part, everything was fine, but today is that occur at startup problems mentioned at the beginning of this post. I tried to search for solutions to this online, and some Web sites suggested to open the Task Manager and try to fix something here. But unfortunately, I can't even open the Task Manager. CTRL Alt Del does nothing, and when I right click on the taskbar, Task Manager option is grayed out. Any immediate response will be greatly appreciated, and if there is any other information I can provide, let me know.

  • iOS 9.3.2 constantly asking to install

    The update iOS 9.3.2 continuously invites me to install it on my iPad 2.  I don't want to install it and so I manually remove the software from my store whenever I am asked to install; However, every day the software shows up (is automatically downloaded on my device) and starts asking to be installed again.

    Why apply continues to download an update of iOS to my system that I deleted?

    In addition, refusal of the update requires a 2-step process with only the option "remind me later" is not to reject permanently the update.  Is it not my right to ignore this update without going through my system harassed with continuous guests... or this option is available for me in a way that I'm not aware of?

    A help for this problem is highly appreciated.

    You have the right in the world do not install the software if you want. However, whenever you connect to a wi - fi connection and the power, it will download the update for you again if you don't the have not installed. Some users take the time to put the URL of the update server in the blacklist of their router to prevent download again, or install enough content on the iPad to prevent the download due to lack of space. If you do a search here, you will see a number of threads with this information. I'm afraid that's the only way to avoid the guests, or to charge your device when it is in flight Mode. As long as it is not connected to the internet when it is powered, it will not download.

    There is an answer for the use of Windows. However, I am on a Mac. I set preferences for "check for updates but let me choose whether to install them." I also disabled automatically update the search engines. It seems to stop the automatic download, but FF asked several times if I want to download 29. How can I prevent the she even ask? I download it, it was a disaster because somehow, the menu button disappeared so I couldn't change anything (I want to keep the buttons on the toolbar, not the button on menu, but without the menu button, that I found myself stuck). So, I went in Time Machine and restored the 28. I just want that he stop asking...?

    Ok thank you! I went to about: config and I saw that these three elements were already set to false. So, maybe my saying things to 'never check updates' was already taken into account there. I'll keep you in the loop, but I hope that t - it. I'm a little upset with FF, however. No previous update never seemed to reduce the functionality/flexibility as this one did. Maybe I just made mistakes, but when the menu button disappeared inscrutably I could make any change. If I didn't have the time Machine I would have (maybe with the exception of which seems rather large procedure again, and who needs that kind of fine? Thanks again, Moses. Polly

    I use a 6 s w iPhone / iOS 9.2.1.  In the last two days some of my apps (Snapchat, FB, Garmin Connect, Instagram Messenger) were often asking access to my camera, photos, micro or contacts (depends on the application that they request access to the).  Almost every time I use these apps they ask for permission to access the same if they have already been allowed access.  My limitations are disabled.  The apps will appear under the parameters of confidentiality as having permission to use the camera, microphone etc, and then, later, this approval will be cancelled.  Everything worked well until 2 days ago.   It's the kind of a nuisance to constantly have to grant permission.  Someone knows how to fix this?

    It's just a bug, then you should try to restart your iPhone. If this does not work, wait for a new update coming, because who can fix it.
