Loopback adapter and zonealarm

Hi,
I tried to install Oracle Enterprize Edition but i got problem with DHCP so i installed a loopback adapter.However I think that zonealarm causes problem .Is there any solution. Do I have to unistall it or can I do something else.
Thanks

the problem is that when i try to install Oracle i get a warning "1 requirement to be verified-
Checking Network Configuration requirements ...
Check complete. The overall result of this check is: Not executed "
and then Enterprise Manager doesn't work

  • Loopback Adapter - No Connectivity

    I installed a loopback adapter when I installed 10g (I have DHCP).
    As of this morning, it say "...limited to no connectivity". I have been unable to repair it. I do have an active internet connection.
    My question is: Can I simply remove that current loopback adapter and install another one?.
    Thanks.

    I cannot believe this...i had the same problem and was able to get beyond the installation of the loopback adapter but was unable to configure the adapter.
    I have spent the last 12 hours researching this very problem...i hope with the help of fellow users that we can find the solution of this problem.
    Anyhow here is what i have learned so far:
    1) you can remove the loopback adapter, the steps are defined in the Oracle Database Installation Guide 10g R2 (B14316-04).
    2) In the future you might do what i did...i created a Restore Point (I am using XP Pro) before installing the Loopback Adapter, so when i got stuck i simply executed the restore process and went back to a state before thr change.
    This is my first take on this issue...i need to install Standard Edition One 10g
    on my xp pro system.
    i hope this helps!
    talk to you soon!

  • Microsoft Loopback Adapter ping failed

    I have a laptop and a desktop both running XP Pro SP2. I followed the instructions to install Microsoft Loopback adapter as part of the Oracle installation.
    On the desktop, I successfully installed Microsoft Loopback adapter. I was able to ping the IP and host name of the loopback adapter and everything works fine.
    On the laptop, I installed the Microsoft Loopback adapter. I cannot ping the Microsoft loopback adapter's host or IP. I can ping localhost and external internet hosts/IP.
    Any ideas?

    Madrid,
    Thank you very much for your help. On my laptop, I have Norton Internet Security (NIS) and there was a firewall rule blocking the traffic.
    This problem is now resolved.
    Thanks for your help, Madrid.

  • Inventory and MS Loopback Adapter problem

    I have a couple hundred imaged machines that all have a MS Loopback Adapter
    in addition to the NIC used for network communication. The MAC address of
    the loopback is always the same. For it's purpose, it is not a problem. For
    whatever reason, ZEN inventory assigns the machines an inventory storer
    string with this MAC number so that each inventory replaces the last. Only
    the last machine inventoried is in the DB. Is there a fix?

    Apparently, the tech who deployed the machines, deployed our image to one,
    inventoried it, recaptured the image, imaged the rest and deployed the
    machines with the same Inventory ID. That's my guess, anyway. Only machines
    deployed by this one tech, and all of the machines deployed by this tech,
    have this issue. Deleting the HKLM\Software\Novell\Workstation
    Manager\InvScanner key (ZEN app to remove key works fine,) setting machines
    to do full inventory and re-inventorying fixes things. PitA, but it works.
    All machines have the same MAC prefix on the Scan File Name but all get
    unique suffix during the process. Is there any documentation on this
    "hidden" part of the process?

  • How to configure MS Loopback Adapter in Windows 7

    Hello all,
    I installed SAP NetWeaver 7.02 SP06 ABAP Trial Version mainly to teach myself some
    WebDynpro Programming for ABAP. Unfortunately this does not work correctly.
    I created a View in a Web Dynpro Component and the Layout Preview does not work.
    I activated the services suggested in
    http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/30129979-011c-2e10-fb9b-a60e0d704c1d&overridelayout=true
    and did use the report RSICF_SERVICE_ACTIVATION with the variants
    WEB DYNPRO ABAP
    WEB DYNPRO ABAP DESIGN TIME
    WEB DYNPRO ABAP TEST APPS.
    In Addition I have set the FQDN as described in the document. I think the problem is the
    MS Loopback Adapter. It is displayed with "No connection" in the Network and Sharing Center. I have no idea
    how to change this. I have set the IP Adress to the on suggested in the Installation Instructions (10.10.0.10, Subnet-Mask 255.255.255.0) but the Loopback Adapter is displayed with no connection.
    If I call a test webdynpro with the Hostname "localhost" it does work, so I think the webserver is running.
    Any ideas ?
    How do I set up the MS Loopback adapter under Windows 7 correctly ?
    Thank you in advance,
    Axel

    Hi Axel,
    Now that you know your local network works correctly for a computer not connected to internet or intranet, you have to do this:
    1- For "No Connection" error (it is not necessary for the sap system to work), it's normal.
    Create a local intranet with a 2nd computer if possible and make a configuration for home network after you will see "Connected"
    2-Use of Pc hostname
    You must configure the "profile parameters" by using transaction RZ10 and activate services (it's not easy, you have to take your time).
    3- Webdynpro
    To see the result of the webdynpro appli, you may know that not all web browser versions are compatible. The recent browsers don't work, use iexplorer8 or mozilla but not google ==> you will solve the problem of "timeout".
    After that:
    Activate the "internet communication framework" by using Transaction SICF. It takes you to "Maintain Services" and then fill Hierarchy Type ==>services, execute to reach at this step:
    default_host/sap/bc/gui and icf ( If you've installed sap java, you will see both sap and sap_java)
    do a mouse right click and select "Activate Service" and choose activate all.
    You can now test the sample via web browser by using locahost.
    Best regards.

  • Is there a way to create a loopback adapter for the mac?

    In the MS world, there is a MS Loopback adapter, that allows to create a virtual network card and simulates that there is a LAN cable connected to it.
    I would like to see if there is a way to do that in the mac world.
    I found this link and I believe is a hint, but I'm not sure if is going to work, I don't want to try it and damage my network settings.

  • Loopback adapter not working - can't install Oracle.

    I'm attempting to install 10g on a Win XP box that is not connected to a network. Installation instructions dictate to install the MS loopback adapter before database installation. I installed it, but I can't get the loopback adapter to work. It can't find itself with ping and the 10g software won't install without it.
    I'm up for a big job using Oracle and I want to upgrade my skills before I interview. This is very important to me. This may sound a bit corny, but I need to pay for a few medical bills and this job has enough of a pay raise to cover my expenses.
    I don't like my current job and I love working with Oracle. Can someone please help me?

  • Using MS Loopback Adapter

    Hi, I am running 10g at home on Windows XP Pro. I have installed 2 network connections, one for home internet (DHCP) and another one created with Microsoft Loopback Adapter for running Enterprise Manager.
    To run EM, I have to disable the DHCP connection and enable Loopback Adapter. Is there a way to be able to run EM even with both connections enabled? Thanks.

    Assuming you set a specific IP address for the loopback adapter, you should be able to specify that IP address in the URL (or an entry in your hosts file that resolves to that IP address) while both connections are active.

  • NIC Loopback Adapter

    Mac friends
    I am facing a problem concerning the creation of loopback adapter.Why do i need a loopback adapter???
    Well my intention is to build a network lab on my imac.
    The first step is to install GNS3 (Lately available in dmg package).Then we got to upload some router IOS's.So far so goodThe routers work without causing any problem to our powerful machine.
    The second step is to install vmWare Fusion,which is a fantastic application to test virtual machines.Now we should install something like OS X Server or Windows Server 2003 or other OS we want to use. I did install Windows XP for network monitoring purposes...
    And now the problem....How can i connect my routers to a loopback adapter in case i want to monitor my network through my mac????
    Does anybody have an idea about connecting my routers to the virtual interfaces that are created through the OS intallation in vmWare????
    Fellows we got excellent machines in our hands and sometimes it makes me angry the fact that i should test somethings in Windows PC's...
    Any help will be acceptable....Thnx

    Excellent test case, may by you should raise an SR and hope it ends up as a bug.
    What happens if you "ping box01.data.local" what IP Address do you get back? You should be looking to get back the loopback address.
    What happens if you do a nslookup 192.168.30.64 and 192.168.1.100?
    Have you tred setting ORACLE_HOSTNAME? Not sure if this is just for the installer or not.

    The installation don't pass the check about lan with the same message as you
    "DHCP configuration detected , you need to configure ur primary loopback adapter to MICROSOFT LOOPBACK ADAPTER". Why?

    I'm not convinced of my euristic solution... can someone explain me why i have to configure the microsoft loopback adapter when i don't have a dhcp configuration?

  • Windows 2008 R2 - Question About Loopback Adapter

    Hello,
    I have the following situation:
    I have two Windows Server 2008 R2 Enterprise with Service Pack 1.
    I use a load balancer (Radware Alteon) in DSR mode, to load balance traffic for between these servers.
    To use DSR, I have to configure a loopback adapter on each of the, with the IP address of the VIP that is configured on the load balancer.
    Everything is working ok, the adapter is recognizing the network and traffic is being loadbalanced perfectly.
    The issue starts here:
    I also configure a health check on the load balancer, so it can check the health of the server, and stop forwarding traffic to a server when it fails.
    One of the failure conditions, is when the loopback adapter fails.
    When the physical adapter fails, it is easy to recognize, because the health check, on its basic, is sent to the IP address and MAC address of the physical NIC of the server.
    When it is not responding, the server is considered as failed.
    However, to recognize a failure of the loopback adapter, the health check is being sent to the IP address of the loopback adapter (that is the VIP) and to the MAC address of the physical NIC.
    The load balancer is doing that perfectly and the health checks are passed when the loopback is up.
    However, when we simulate a loopback failure, by disabling it, the load balancer does not recognize the failure.
    Instead, we just see, in the load balancer statistics, that the server response time is very high (more than 3500000 ms) but the server is up.
    The check that we use is a simple ICMP ping request, and we are expecting an ICMP reply withing the specified configured period of time (that is, the timeout).
    We started a sniffer catpure on the switch connected to the server.
    We saw the following behavior:
    When the loopback is disabled, the server still replies to the ICMP requests, but with ICMP redirect (redirect for network)
    The ICMP redirect message is sent fromt the source IP address and MAC of the physical NIC.
    Then, another ICMP request is sent, and here is also a weird behavior:
    The request is sent from the source IP address of the load balancer and source MAC of the server, destination IP address of the loopback adapter (that is the VIP) and destination MAC of the load balancer.
    It is clear that this ICMP request is from the same "ICMP session" that was just sent, because it is being sent milliseconds after the first request and ICMP redirect reply. It is not a new health check, because a new health check will be sent after
    the interval configured (5 seconds after the first ICMP request).
    I don't know if this request is being sent from the server, which means that it spoofs a request from the load balancer by using its IP address as the source, or is it a request being sent from the load balancer, which means it spoofs a request from the server
    by using its MAC address as the source.
    My question is, if anyone saw such behavior of:
    1.) ICMP redirect from the server on Windows 2008 R2 when the loopback is disabled.
    2.) A seconds request within the same timeframe of the first request, not a part of a second health check.
    I configued the loopback adapter properly, with the weakhostsend and weakhostreceive enabled, and with forwarding enabled (using netsh).
    I tested the same topology with Windows Server 2003 Enterprise Edition Service Pack 2.
    On this OS, when the loopback is disabled, it just not sending an ICMP reply at all.
    Thanking in advance, Udi Dahan.
