Cannot connect to EM on ODD guest from Windows host

Hello,
I cannot connect to the Enterprise Manager in my guest VM from my host. From a IE v8.0 browser, the recommended link https://192.168.56.101:1158/em fails to connect.
I installed Oracle VM VirtualBox 4.0.4 on a Windows 7 laptop and imported the Oracle Developer Days (ODD) VM appliance. Within the ODD VM I started Enterprise Manager with the cmd "emctl start dbconsole". I confirmed the listener is up and running in the ODD VM.
I checked my Windows Firewall and the MS Telnet Client is allowed through on IP 192.168.56.101 on local port 1158.
Suggestions?
Cheers,
David

Apple Support could reproduce the problem, and provided the solution:
Assuming that VNC is configured in the sharing prefs (under Apple Remote Desktop), it is enough to disable ARD in the sharing prefs. Once you do this (presumably via Apple Remote Desktop) you'll obviously lose your connection.
To restart ARD again from the commandline, connect to your server with ssh and issue the following commands:
sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/k ickstart -activate
sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/k ickstart -restart -agent
now you should be able to connect to your server with ARD again....
.... and all connections with VNC should work as well!!
splendid, thanks apple support!

  • Cannot connect properly to Oracle on Linux from Windows

    Good day all,
    I’ve got 2 virtual machines running on my Mac:
    -     Centos 5.4 with Oracle 11gR2
    -     Windows 2003 server with Oracle 10gR2
    From Linux box I have access to Oracle database on Windows box (both directly and via a database link), however from Windows I have problems accessing the oracle database on the Linux box.
    From Windows, if I try to set up a connection using Oracle’s SQL Developer using connection type “Basic”, I get “IO Error: The Network Adapter could not establish the connection”. When I use “TNS”, then it works.
    From the linux box it all works fine as the “oracle” user, but when I log on as another user (in this case “informatica”) it doesn’t work properly any more.
    To sketch what both environments look like.

    [ the sequence of dots means I took out a whole lot or lines with virtually the same information, only different port(s) ]
    What’s noticeable is that port 1521 seems solely assigned to the localhost IP-address, 127.0.0.1.
    Another thing I noticed is that from a different user in Linux, so not “oracle”, using SQL Developer I cannot access the local Oracle database via TNS. When choosing TNS the dropdown box for “Network Alias” – which normally is populated with entries from TNSNAMES.ORA – is completely empty. On a “users and groups” level I basically assigned all the groups the oracle user is member of, to the other user (called informatica).
    And to make it even more interesting, at first it worked using “Basic” (in SQL Developer), but since implementing the TNS_ADMIN environment variable, it doesn’t work at all !!!
    Trying it via SQLPLUS as the “informatica” doesn’t work either:
    [informatica@ilmserver ~]$ sqlplus system
    bash: sqlplus: command not found
    I’ve assigned the “dba” group to “informatica”, or rather, I have assigned all groups to the “informatica” user as the “oracle” user has.
    Needless to say I am no Linux expert, rather a quite inexperienced Linux-user.
    So bottom line, the situation I’d like to be able to create is the following:
    •     Linux Oracle DB accessible from “informatica” (or any other) user on Linux, via both TNS and java-based
    •     Linux Oracle DB accessible from remote machine (running Windows 2003 server) via both TNS and java-based
    •     And for Informatica to work properly, it says it needs the TNS_ADMIN environment variable, so the “informatica” user must have full Oracle connectivity with TNS_ADMIN in place.
    Any help is greatly appreciated.
    Thanks, Patrick

    Hi Billy,
    Thanks for your elaborate answer.
    Not sure whether I can use it though, since the application using the oracle database (i.e. Informatica ILM 5.3.2) appears to have a specific need for TNS.
    I thought I had a solution (not the prettiest for sure) by just copying TNSNAMES.ORA to an accessible location, change ownership to "informatica" user, have TNS_ADMIN point to it, and Bob should be my uncle. Well... he isn't!
    In SQL Developer when I choose TNS as connection type, the drop down box is STILL empty.....aaaaahhhh!!!!!
    I was advised to play around with primary groups, so I tried oinstall and dba as primary groups for informatica user, all to no avail.
    And I can't even test it with SQLPLUS because I don't have access to it as "informatica".
    Who knows what the exact reason for that is... I know I'm a far cry from an experienced linux user, but I assumed that having the Oracle Home bin directory in PATH, and assigning the oinstall group to informatica user, would ensure access to to any executable in there. Well... NOT!!!
    +[informatica@ilmserver ~]$ sqlplus system@orcl+
    bash: sqlplus: command not found
    This is driving me nuts. Thought that finding a solution for this wouldn't be this hard, but essentially I've been digging for 3 days now.

  • I cannot connect to the Internet after installation of Windows Vista Ultimate edition.

    I cannot connect to the Internet after installation of Windows Vista Ultimate edition. For some odd reason, it seems my ethernet has not yet been installed to my operating system and I do not know how to do that even with the internet, I have the LAN cable hooked up to my computer but I do not know exactly what to do about it. Is there some sort of driver I need to install, or what? How do I do that without the internet?
     This operating system is on a separate partition to my other operating system that is connected to internet already (Windows Vista Premium) that I do not wish to use anymore because of it's corruption. I tell you this because you may know a way of finding the driver files on my previous operating system that I may be able to transfer to the other.

  • Problem Connecting to Shared Printer on Leopard from Windows XP

    Hey guys,
    Just installed Leopard yesterday, and I have a Canon PIXMA MP160 printer connected via USB.
    I have set the printer to be Shared, and enabled Printer Sharing in the Sharing preferences.
    However, when I try and connect to the printer from a Windows XP laptop, it says: Access Denied, Unable to Connect.
    I imagine that this is because I would have provide a username / password combo in order to access the network resources on my Leopard machine. I just can't figure out how to send the credentials, or disable the login necessity if needs be.
    If this isn't the problem, or if it cannot be fixed then the alternative is to connect the printer to my router, which shares it via SMB. Now that's fine when I want to connect to it from Windows, but I can't figure out a way to set it up on Leopard.
    The MP160 driver that comes with Leopard isn't marked as "Modern" which, according to the documentation means that it cannot be used to install IP or Windows Shared printers.
    So my question is, to sum up, is there a way to fix the access problem when trying to access a shared printer on Leopard from Windows, and is there any way I can install and use the printer from Leopard while its shared from my Router via SMB?
    Thanks in advance.
    Edit:
    I just thought it would be helpful to say that I'm able to connect and browse through SMB shares from Windows Systems, and I'm able to connect and browse through shared volumes on Leopard from Windows. It's just the printing that's not playing fair.
    Message was edited by: Jasarien

    I had Bonjour for Windows working on two XP machines before I upgraded to Leopard. After that when the Bonjour printer would not work I deleted it from the XP machines and re-ran the Bonjour Setup App. It can find the printer every time, but it will not finish and will give me an error instead.
    I've also verified that I have Printer Sharing turned on and the printer is specifically set to be shared. I'm out of ideas.
    Has anyone heard reports of Bonjour 1.0.4 not working with Leopard or just being buggy under similar circumstances? If that's not the problem, then I must be missing something. Suggestions welcome.

  • TS2706 I cannot connect to my airport (time capsule) from a Windows PC

    Any information on how to connect to an aiport extreme (really the time capsule) from a Windows platform. Have no problem from our Mac's but cannot connect from a windows based platform.  I haven't been able to find any recent posts to help with this problem.

    First off, Archon23, what you want to achieve is possible.  I have access to both my Time Capsule (TC) and the USB drive connected to it, from a Win. 7 and Win. XP machine.
    Here is what I see from the Windows side of things:
         From My Computer - TC USB Drive (Y)
         From Windows HomeNet - Time Capsule:
    Now getting there is the trick.
    One caveat before proceeding:  I am not well versed in Windows Networks, Windows Sharing and Firewall settings so some of the following may not be elegant, may not be absolutely required, and may not be the best way of getting there.  But it is what I did to see both the TC drive and it's attached USB  drive on the Windows side of my network..
    1.) First, I added Airport Utility to the Inbound rules of Win 7 Firewall
    While poking around my Network Sharing and Firewall settings trying to figure this out, I got a Pop-up recommending I do that.  AND I did that. Oh, and while you are at it, make sure you have a Home network established. 
    2.) Next, on a hunch, I installed a USB Wi-Fi Adapter (under $20) to my Win PC, enabled that Wi-Fi connection and disabled my Ethernet connection.  I was getting no where on this matter with my Ethernet connection to a DSL Gateway.  But with a Wi-Fi connection to my AirPort Express Base Station, I made progress.
    3.) Finally, while poking around my Network Sharing Center some more, one by one I started the various network device Setup Wizards in there, and Trouble Shooters, to find the elusive TC/USB devices in question...AND voila, it worked.   And it's stable, been this way for going on two weeks now.
    Good luck.

  • Cannot Connect to iTunes Store - Download music from iCloud to iphone 4s

    Hi,
    Desperate for help.
    I have the iTunes match service on my iPhone 4s. All of the songs in the cloud are showing as available to use but when I tap a song to play the song appears on the screen but not play. I have tried using my 3g and internet connection but to no available. When I try to download an individual song by tapping the iCloud logo button I get the message “Cannot Connect to iTunes”.
    I am definitely signed in to iTunes on the phone. iTunes match is definitely switched on.
    I have tried switching the phone off and on using regular and hard reset method. Every other aspect of the phone is working fine. I have even download a new song on iTunes successfully.
    Regards,
    Shaun

    I am able to log into iTunes from my iPhone (i checked my account info)
    But, I am unable to update any Apps through the App Store.  Everytime I try, it comes up with the error "Cannot connect to iTunes Store"  
    And that's where I'm stuck.

  • "Cannot connect to iTunes Store" when access from Video/Music

    When I open "Video" or "Music" app and try to access iTunes Store from inside the app, the message "Cannot connect to iTunes Store" appears.  I have access to internet and still can download applications from app store.  Please help me fix this.  Thank you.

    Saw this on another post.
    Applecare Senior Advisor Txx Bxxx (I have his contact info in an email he just sent) just confirmed with me that the problem people are having with the App Store not loading is an apple issue with there servers, ITS NOT YOUR IPAD so don't go restoring it!   It's not happening to everyone however but they are looking into it, its really hit or miss.

    Try this first - Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
    This works for some users. Not sure why.
    Go to Settings>General>Date and Time> Set Automatically>Off. Set the date ahead by about a year.Then see if you can connect to the store.

  • I cannot connect to my basic SQL server from Visual Studio Ultimate 2013? Error 40 - Cannot establish connection

    I just started learning ASP.NET through a book, and it asks to connect to "your" SQL server and explore a .mdf file. I've been trying to install SQL, but I only just now got a working installation, and even then it won't let me install the Management
    Software. Whenever I try to connect, I get this error: http://puu.sh/7F2JY.png
    This is exactly what I do to connect:
    1) Open project
    2) Navigate to the Server Explorer
    3) Click on connect to database
    4) In this menu, I can see me Machine name on the top part, which I think means that it's picking up my server runningh
    5) On the bottom, it wants me to enter a database name. I think this may be my problem, as I have no idea what to do here.
    Also, when I double click on the database file, I get this errpr (52): http://puu.sh/7F2Yw.png
    I really don't know what to do here, so post any tips down below

    Hi,
    Did you choose the correct Server name? It should be the machine name where you installed SQL Server on.
    Is it empty when you open select or enter database name drop box in the Add connect dialog box in the Visual Studio 2013?
    “Update: I re-installed, and then used both installers. Now I have the Server Management tools, but I still cannot connect.”
    The screenshots indicates that the SQL Server is not accessible.
    Do you mean that you are not able to connect SQL Server by using SQL Server Management Studio?
    If so, make sure that SQL Server Services is started.
    Please check out the following articles for details:

  • Cannot connect to Oracle 10g XE Server from Client

    I have tried in vain to connect to the Server from a client installation using both browser and SQLPlus. Someone help me out pls...
    Glogo.

    I have read the SelfStudy many times but Sheila can't help me. I have installed 10g XE Client on a different pc and tried connecting as follows to no avail:
    FROM Run SQL Command line; I entered "conn glogo/*****@GServer:8080/apex" the report I always get is
    ORA-12170: TNS:Connect timeout occured
    From Internet Explorer; I entered "http://GServer/127.0.0.1:8080/apex" the report I get is internet explorer cannot display the webpage
    I ensured the listener is on by typing LSNRCTL STATUS on the command line of the system running the Server. The report indicates that the Listener is ready.
    I am still wondering what is wrong! I have also changed network setting from DHCP to static IP without results. What next friend(s)? Do you know?

  • Cannot connect to Oracle 8i with IIOP from JDev3.1

    Hi,
    I have the problem of connect to Oracle 8i with IIOP from JDeveloper 3.1 when I build application with BC4J. I can connect to my Oracle 8i database with ODBC easily but failed with IIOP. Does anyone here has the same experience?
    Any help will be appreciated. Thank you.
    null

    Hi Daniel:
    I've solved the problem mentioned above. It requires two settings:
    I) Enabling Multithreaded Server Support for IIOP Clients;
    II) Listener's listening to port 2481
    Of course you should have installed JServer into your Oracle 8i database.
    In your init.ora file, you should have the following two lines:
    mts_dispatchers = "(PROTOCOL=TCP)(PRE=oracle.aurora.server.SGiopServer)"
    mts_dispatchers = "(protocol=TCP)"
    To confirm this you may use SQLPLUS to list the parameters of the database setting:
    mts_dispatchers string (PROTOCOL=TCP)(PRE=oracle.aurora.server.SGiopServer), (protocol=TCP)
    mts_servers integer 1
    And in TNSnames.ora file the setting should like this:
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = wangsvr)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = wangsvr)(PORT = 2481))
    All these two settings ( init.ora and tnsnames.ora ) can be done with "Database Configuration Assistant" and "Net8 Assistant"
    I solved my problem this way, your problem may not the same but anyway you may try it.

  • Cannot connect to XE after following "How To" Windows XP Pro SP2

    Hi Sharon and everyone,
    I have read all related posts, the how-to and tried many times including restarting XE but still cannot connect using SQL Developer. I already have a small schema created using ths SQL Window of XE and can connect using "Toolkit for Oracle" (though this behaves erratically and I don't like it so far). I have succesfully connected also using the XE ODBC Driver from MS Access and INSERTED Rows in a table in the Schema.
    I want to use SQL Developer but I get the following message when trying to connect (this PC is Server and Client) :
    "Status : Failure -Listener refused the connection with the following error:ORA-12505, TNS:listener does not know of SID given in connect descriptorThe Connection decriptor used by the client was:127.0.0.1:1521:xe"
    Inputs used :
    Username : system
    Password : *******
    Basic Tab :
    Hostname: 127.0.0.1
    Port: 1521
    SID: XE
    TNS TAB:
    Network Alias: "XE" (this is the default and there is no mention in the How-To of overriding it at all ! )
    If I change the Network Alias to "EXTPROC_CONNECTION_DATA" or "ORACLR_CONNECTION_DATA" I get the same message.
    If I try using "Service Name" instead of "SID" I get a similar message but with "does not currently know of service requested". ( All 3 Network Alias values tried)
    Please can you help me ?

    Hallo Sue,
    Thanks for a prompt reply. It helps to know that the Basic and TNS (and I presume also the "Advanced") Tabs are mutually exclusive.
    This does not however solve my problem as when I enter the SID "XE" in the Basic Tab I get the error :
    "Status : Failure -E/A Exception :Connection reset" the first time I click on "Test".
    If I then click on "Test" a second time I get "Status : Failure -E/A Exception :Connection reset by peer: socket write error "
    The 3rd time I get :
    "Status : Failure -E/A Exception :Connection reset" the first time I click on "Test".
    The 4th time I get :
    "Status : Failure -Listener refused the connection with the following error: ORA-12505, TNS:listener does not currently know of SID given in connect descriptorThe Connection descriptor used by the client was:127.0.0.1:1521:xe"
    If I check using lsnrctl status the listener is listening on port 1521 (protocol=tcp, host = swisspair2).
    A further problem I have had since installing XE which may be related to this problem is that I cannot start the Database Home Page (despite reading all threads similar on the XE Forum I can't resolve this either). The error I get when trying to start the Database Home Page is "The connection was refused when trying to connect to 127.0.0.1:8080"
    Could you suggest any problems that I may have on this "Server/Client" PC (Windows XP Professional SP2)

  • My win 7 home premium cannot connect the sharing printer (EPSON L1100) in Windows server 2003 it say "Windows cannot connect to the printer. Accses denied"

    in My office there is a win server 2003 R2 computer, i install a printer Epson L1100 in that computer, and it successfull, and i can print using that printer from that computer..
    I already share this printer, but when i try to connect the printer from my laptop using OS Win 7 Home Premium.. it has error
    "Windows cannot connect to the printer. Accses denied"...
    and then i try connect using other computer but same OS (win 7 Home premium) it still has same error...
    i usually connect to the server computer using //(the ip of computer) , for example
    //52.30.20.66 .. that is my IP server..
    and than i right click in shared printer which appears in windows explorer, and i choose
    Connect...  but it contain error "Windows cannot connect to the printer. Accses denied"..
    anyone know the solution from this error???
    i`m sorry if my english is bad.. i`m from indonesia

    Got a local password/username on your Win7 ? Create the same on the 2003R2 as you seem in workgroup
    net user /add useraccountname mypassword
    net localgroup users useraccountname /add  (I think it's users the name, you can validate to be sure) or
    net localgroup administrators useraccountname /add in worst case.
    nb, or add the user guess in the printer share security

  • Cannot connect to wifi on desktop computer w/ Windows Vista

    So as stated above, I cannot connect to the Airport Extreme wifi with my Sony Vaio desktop computer. My iMac, iPhone, PS Vita, and all other device can connect to it easily, but when trying to connect to the internet using my Sony Vaio desktop, I cannot. At first it showed up on the list of available connections, but then after calling TWC, they did something and it let it connect to the internet "with limited access". But after my father tinkered with it to try and give the computer full access, it cannot connect again.
    In short: My Sony Vaio desktop computer running Windows Vista cannot connect to my Airport Extreme. So could anyone please help?

    Did you try plugging in by ethernet?? Just to be sure there wasn't some fundamental issue.
    If it works by ethernet and not wireless, then this is not at all unusual. Vista has the worst wireless drivers ever developed along with the worst wireless management.. an upgrade to XP or Win7 is strongly encouraged. .either direction is an upgrade.
    Make sure the AE has all SMB compatible names..
    Short, no spaces and pure alphanumeric. Do not use apple names with spaces and apostrophe.
    Use wpa2 Personal security with a password of 10-20 characters again pure alphanumeric.
    Use fixed wireless channels, try 1, 6, 11 in turn.
    No improvement download the latest intel drivers (or whatever wireless card your laptop uses) direct from Intel. If that doesn't work try some earlier releases.. not always the latest is bestest.
