Blocking Access from Ubuntu 9.04 Virtual Machine

Hi Everyone
We have blocked access on Perimeter Routers for Some specific ports like telnet , SSH etc
and as per access policy users are granted access within the organisation for Servers at Data Centre based on there IP addresses
If some body installs Ubuntu 9.04 Virtual Machine and then invokes virtual XP some how  the user gets 10 series IP and still manages to access the servers
How can i block the same
While checking for IP Accounting on Router there are no traces on the Vitual IP but server login details shows the IP address from whcih accessed with source IP as 10.x.x.x
Regards

I need C Api to connect from Ubuntu 9.04 to Oracle 8 database, is ODBC the only way to do this ? There is an opensource solution to connect without installing database on the client machine ?You certainly dont need a full database install on the ubuntu client, client components only are required.
Because your target is a downrev oracle database version you might need to use client compoents like linux 9i to be successful :- [http://www.oracle.com/technology/software/products/oracle9i/htdocs/linuxsoft.html]. The more modern 'instantclient' [http://www.oracle.com/technology/software/tech/oci/instantclient/index.html], [http://www.oracle.com/technology/tech/oci/instantclient/index.html] does not appear available at this verion. Its possilble this version might have issues when installing this version on ubuntu 9.04 ... i simply don't know and too hard for me to look up.
I personally am unaware of any thin client driver technology that would help you here, that isnt to saythere isnt one.
This si not an area i am now current in, i merely really wish to say you do not need a full database install.

    Edited by: Rahul K on May 17, 2013 9:12 AMExactly like you would if that virtual Windows server were a physical server in your data center.
    Install your client products, including the oracle client, on your host os.
    Create a tnsames file that has an entry for the database on our virtual server.
    Just like a real server, your vm must have a fixed IP address so that client processes will know how to find it.

  • How to access PS(32) in XP virtual machine under Win7(64)?

    I have a PC running 64-bit Windows 7 and Photoshop CS4 std. (both 64- and 32-bit versions installed).
    My HP z3100 printer drivers are 32-bit (64-bit unavailable until june 2010)
    I loaded the XP virtual machine and downloaded the existing HP 32-bit drivers there, thinking I could print in that environment.
    Using explorer, I found PS32 on my 'real' machine, but attempting to start it results in an exception. Bridge CS4 works ok.
    1. Am I doing the right thing to print this way? I don't think I can load those drivers into my 64-bit environment.
    2. Is this the right way to access my PS32?
    3. If so, why does it crash? If not, what should I be doing?
    Thanks

    Adobe kindly increased my activation count. Here is the last part of my chat:
    Kesavan: It is activated already on the 1st machine.
    Eric: Then why doesn't it work?
    Eric: It *does* work in the 64-bit part of the machine; it does *not* work in the 32-bit part
    Kesavan: I understand that it takes as two activations and you need to deactivate it from any of the machine to get it activated on the other.
    Eric: Yes that is the standard protocol. But it does not apply here. This is new.
    Eric: I do not want to go into 64-bit PS to deactivate it every time I start the 32-bit version, then do the same thing in reverse on the way out.
    Kesavan: As we value your business with us as an one time exception I've increased the activation count by 1 and now you can go ahead and get it activated without any issues.,
    Eric: okay let me try.
    Eric: Yes that worked. Thank you. Please consider this situation carefully - it will occur again (other users).
    Eric: Thanks again
    Kesavan: You are welcome.

  • Need to access the Power shell within Virtual Machine Manager.

    Hi all, I have a VM that shuts down everyday between 9-10PM.  I would like to get a script to start it up at 11PM.  However, the issue I have that if i run the powershell command "start-vm -servername" from the Powershell within the Virtual
    machine manager it works without an issue.  However I can not get my script to use that powershell.  If I use the normal powershell, that command does not work.  Hopefully that makes sense.
    I'm running Windows server 2008 R2 standard with VMM 2008 R2.
    The VM is being decommissioned in Q1 2015, so this would be the most cost effective way to restore functionality.
    Any help would be greatly appreciated.

  • Migrate from vmware to oracle virtual machine having some error

    Hi

    Thank you for the information. The link you have mentioned is about migration the environment of a machine to a VM. But i'm looking for migrating an Oracle Database 11g from a Physical Machine (Linux x86) to a Virtual Machine( Linux x86) created using Oracle VM. Can you help me out in this.
    Thanks :)As far as I understand it this is not really VM related.
    You have an existing linux machine .... uname -a ... with a partiocular OS and kernel and set of packages installed ....
    And a guest VM running linux ... uname -a .... with hopefully the same/similar OS and set of packages installed, similar users, directory layout etc.
    And you wish to get the Oracle (Classic RDBMS) home software cloned/migrated and an oracle database cloned/migrated.
    There's a number of different senarios here ... can i help you out .... (the answer is I could but i dont have time).
    The start point is good planning and careful notes if you are attempting to change any versions / layours etc.
    You might have stages like (this is a top of head fagpacket and perhaps not best terminology):
    - Install basic Linux software on VM guest.
    - Install additional linux packages
    - create groups, users, directories, system parameters etc.
    - Create or clone oracle home.
    - clone oracle database by eg RMAN or otherwise.
    Different forums may help different stages if necessary.

  • Switching from MSJVM to Sun Virtual machine

    I am a developer who wants to switch from the old MSJVM to the Sun virtual machine, I wanted to know what are the differences between them?
    What does one has more than the other?(besides support).
    Also i have heard that my software might not be totally compatible with the Sun's JVM. I have compiledin 1.3
    Thank you.

    If in Java code written for MSJVM you do not use MS Java specific classes then you can compile your code with any SUN Java compiler. MS Java is the same as SUN Java ver.1.1.
    While writing Java code MSJava I used pure AWT classes instread of MS specific GUI classes. Then this code I recompiled with SUN Java without changes.

  • Block access from other subnets 2921 router

    Good day,
    I have a 2921 router...
    I got many subnets on network.. What I want to do is block access to one of my networks and allow all other subnets to browse the web.
    I have;
    192.168.4.0/24
    10.20.50.0/24
    10.20.40.0/24
    10.20.30.0/24
    10.20.60.0/24
    I want to block access to 10.20.60.0 from all other networks while allowing them to access the internet

    If what "Jon" said is correct you could do something like the following.
    ip access-list extended VLAN20_ACL
    deny ip 10.20.50.0 0.0.0.255 10.20.60.0 0.0.0.255
    permit ip any any
    ip access-list extended VLAN20_ACL
    deny ip 10.20.40.0 0.0.0.255 10.20.60.0 0.0.0.255
    permit ip any any
    ip access-list extended VLAN20_ACL
    deny ip 10.20.30.0 0.0.0.255 10.20.60.0 0.0.0.255
    permit ip any any
    ip access-list extended VLAN20_ACL
    deny ip 192.168.4.0 0.0.0.255 10.20.60.0 0.0.0.255
    permit ip any any
    int vlan 20
      access-group in VLAN20_ACL
    int vlan 30
      access-group in VLAN30_ACL
    Now technically, 10.20.60.0/24 could still get to the other subnets, but the return traffic would be blocked.
    And you could always change the permit ip any any to just HTTP traffic, etc. Depends on what you want to do.
    Although it might be a better idea to configure ACLs on the firewall. It would be easier to manage that way. If traffic has to go up to the ASA to get back to the other subnets.

  • Using .htaccess file to block access from certain networks

    Does anybody have any tips on getting a .htaccess file to work to block access to my Web Access server from certain network ranges on SuSE 10 SP3 with GW 8.0.2.
    It does seem like the file does anything? With Web Access I'm not exactly sure where to put the file. I used to accomplish this using iptables, but I was seeing if I could do the same with .htaccess.
    Thanks!

    You can block a range with the .htaccess file, for example by defining the range as
    Code:
    order allow,deny
    deny from 10.0.
    allow from all
    ...that would block all 10.0.0.0 upto 10.0.255.255 addresses
    You cannot use this file in tomcat, so useless I think... but as Apache is used as frontend for the tomcat webacc application and you might be able to edit the gw conf apache files to include the range denies (which by default can be found in /etc/opt/novell/groupwise/webaccess/gw.conf).
    Maybe this thread might help as there are some examples in howto include denies in the .conf files.
    Deny IP Ranges in httpd.conf Apache Web Server forum at WebmasterWorld
    Do make a backup of you current gw.conf in case it blows up :)

  • Adobe X cannot print from Win 7 VMWare virtual machine

    I've created several virtual machines using VMWare Workstation and VMWare fusion.
    I've installed Win 7 Pro 64bit. I've installed either Office 2010 32 bit or 64 bit.
    When I open any PDF file and click File Print. Adobe crashes. I get an OS error message the program has encountered an error and I can search online for a solution or close the program.
    Either option results in the application closing.
    Is this common? Can anyone else verify the same results?
    Will this be patched or is it by design?

  • Time Capsule blocks access from outside

    I just changed my Airport Extreme with a Time Capsule using the "replace existing airport" option in the airport utility. I have a MacMini attached with ethernet to the Time Capsule that runs as a server (web server, ftp server, vnc) that can be accessed from the public Internet. However, after upgrading to the Time Capsule I cannot access the MacMini server from the Internet. I have tried all the settings I can think of. Both NAT with default server and NAT with configured services fail to work.
    Are there any changed behaviours between these network equipment? (the Airport Extreme is the fast-ethernet version). Both uses the latest firmware and software.

    There was a problem in the ISP settings - the external IP address changed when i swapped the Airport Extreme with the Time Capsule...

  • Laserjet 1320 on win 7 (64bit) - cannot access from a networked XP Pro machine?

    I have a Laserjet 1320 and a Officejet 6450 attached to a win 7 (64bit) machine - both work fine.
    Have a home workgroup network established with an XP pro machine.  Both printers are "shared" etc..
    I can access the Offiejet from the XP machine, but cannot get access to the Laserjet.  Claims that
    the proper Driver cannot be located.  Have downloaded the PCl5 driver to the Win 7 machine, but when
    I point the XP machine to the HP PCL5 Driver folder on the win 7 machine it still cannot find the proper driver.
    Any help will be appreciated.

    Hi Don
    Thanks for the reply.
    The version of Visual Studio being used is 2002 (getting on a bit now).
    We had a play about with the way we installed the MSI installer we had created that installs the Crystal Reports runtimes (merge modules) and managed to get it to work on both Windows 7 32bit and 64bit.
    The solution was a weird one, but seemed to work (but was different to what I had done before to get it to work).  We made sure the MSI was local on the PC and right-clicked the MSI and selected the ''Troubleshoot Compatibility' ' option.  Not 100% why this would work, but it seems to have done the trick.
    Many thanks for your help.

  • Block alignment for NetWare 6.5 Virtual Machines

    I have an enviornment with multiple virtualized Netware VM's running on vSphere. Some were converted using VMware's P2V software other's were migrated using the SCMT.
    My question relates to block alignment at the NSS layer. I have the block alignment handled up to this point:
    SAN Luns: 64kb
    VMFS Partitions: 64kb
    VMDK files: If created using the vSphere client 64kb. If P2V ???
    NSS partitions within VMDK: ???
    What is the default block size for the NSS partitions in Netware? I there a way to check?
    If they are not at 64KB, Is there a tool available to re-align them to 64kb?
    Thanks for the help!

    The default and only available block size for NSS is 4k. No alignment should be necessary as 4 divides evenly into 64.

  • How to access from Ubuntu PC to an external HD connected to Airport Extreme

    Hi,
    I have an external Hard drive connected via USB to my Airport Extreme.
    I have a MacBook (of course) and also a PC under UBUNTU.
    I can perfectly connect to this external HD from the Mac but I don't know how to do with the Ubuntu PC.
    From Unbuntu:
    1) I tried to "ping" the Airport: it's OK
    2) I tried to "connect to a server": the Airport, nor the HD, is not seen
    Can you help me ?

    I am not sure what path I should be using in the script now that it needs to find the volume through the Airport.
    If the volume is already mounted then the path will be in the format /Volumes/<name>/... where <name> is the name of the sharepoint as it appears on your Desktop.
    If you're still unsure of the path, drag the relevant folder from your desktop into your script (or a blank AppleScript document). AppleScript Editor will ask if you want to copy the folder contents or an alias to the folder itself. Choose the 'Alias' option and you'll see the actual path to this folder appear in your script window.

  • Samba: write access from Ubuntu but not arch ?!?

    Hi !
    I am currently dual booting Arch and Ubuntu on my laptop and have a problem with getting write access to samba shares on an Arch mythtv backend.
    I have full write access when using Ubuntu on the laptop, but when I boot into Arch I can see the shared folders and their contents, but I do not have write access.
    The laptop Arch and Ubuntu user names are the same, as are the passwords (in case that matters).
    This is the smb.conf on the Arch backend:
    [global]
    workgroup = MYGROUP
    netbios name = BACKEND
    server string = laffi
    wins support = yes
    wins server = 192.168.1.103
    log file = /var/log/samba/log.%m
    max log size = 50
    map to guest = bad user
    socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
    local master = no
    dns proxy = no
    guest account = laffi
    [public]
    path = /home/laffi
    public = yes
    only guest = yes
    writable = yes
    Any ideas ?

    Nothing ?
    This is currently the show stopper for switching my laptop to Arch, so any help with getting this problem sorted will be much appreciated ;-)
