How to close TCP 443 and 902?  (WS 9.0.1 on the Linux host)

When it is hosted on Linux (Ubuntu 12.04), VMware Workstation 9.0.1 listens on ports TCP 443 and 902 on all network (0.0.0.0) interfaces.  This happens as soon as the host operating system is finished booting, even if you do not launch the VMware GUI or run the virtual computer guests.

This creates a potential attack surface, on a machine that can be used on hostile networks and normally has no open TCP ports listening.

These two headphones can safely be stopped?

Or can reconfigure us these headphones link only to the loopback address (127.0.0.1)?

Of course, we could solve this problem by activating the Linux Firewall on the host computer, but this seems to be using a sledgehammer to crack a nut!  There is no reason for VMware Workstation business link to nothing else than the loopback address, so it would be easier if there was a change for VMware startup scripts to solve the problem at the source.

Thanks for the pointers!

I did not, but if you do not use the shared virtual machine so I see no harm to comment on the entries above.  It wouldn't break anything permanently and you can certainly easily Uncomment if/when necessary.

  • How s/n know when and what account perform a function using the database link?

    Dear,

    My application of the CIM team asked DBA to create new function and run it. Function must use the database link for remote database data. So I need to create a new database to their licensing link. Cause we guess we'll experience the performance issue after the user performs this function, or another question and errors may occur. So we want to know when and who use this feature that connects to a remote database through the new database connection in advance. And I also need to know when and which connect to the remote database using this new database link. We have no idea to get this information?  Can anyone recommend how do? Thank you very much.

    Best reqards, Otis.

    Check what business purpose, it will solve.  If the function is so safe, why everyone will use. Only admin people should access.

    All of these additional controls of this kind must be avoided as much as possible to improve the overall performance of the application.

    Still if you need, see the database audit mechanism, specifically designed for this type of activity.

  • How to change the virtual IP addresses in 6.5.1 on the Linux host?

    I am running Workstation 6.5.1 on a 64-bit Linux host (Fedora 10).

    The application of "Virtual Network Editor" is distinguished by its equivalent in Windows.  It is quite reduced in functionality.

    What I need is a way to change the virtual IP addresses.  In the editor, I can only change the overall range of subnet (network address and the sous-masque).  It works very well.  However, I can not change the individual IP addresses in there.

    In particular, I need to change:

    .1 = the host itself

    .2 = services internal VMware (server proxy DNS, router, gateway, NAT, DHCP etc.)

    How can I assign these on Linux?  Pour.2, I saw the "nat.conf" file in the directory/etc/vmware, under the number of the device (in my case vmnet8) vmnet.   Pour.1, I've seen this in a number of places, the DHCP server, and others.  Where does get this information from VMware?  What I don't want is to have to change this IP address in many places, because it will become easy to get out of sync.

    If I just use "ifconfig" to change the IP address, it is an approach of brute force that works, but of course it will not survive a reboot.

    Traditional networks of the host Linux tools are unaware of the vmnet addresses.  Somewhere, they are configured with VMware, not the distribution of the host.  So, I wonder where it is.

    Thank you!

    Josh,

    Here is what I do on my VMWare Wks 6.5.2:

    Files to edit:

    1 /etc/vmware/vmnetx/dhcpd/dhcpd.conf

    Change the following:

    (a) range

    (b) option domain-name-servers {10.10.10.254}

    (c) {10.10.10.254} option routers

    2 /etc/vmware/vmnetx/nat/nat.conf

    Change the following:

    (a) {10.10.10.254} ip - address of the NAT gateway.

    3 /etc/init.d/vmware script

    (a) check a function called vmwarestartvmnet()

    (b) after the/vmware-networks - the beginning of the line, add:

    ifconfig vmnetx xxx.xxx.xxx.xxx {ip host address we want to}-> vmnet1 ifconfig 10.10.10.253

    This works perfectly for me. The only thing is that, once you change these files, make sure that you get a copy of them. Otherwise after any update or configuration change who will be overwritten.

    I hope that VMWare will come with a better way to do that instead of hacking these files manually.

  • The Linux host, guest of WinXP, host has 2 network cards, how to choose which NETWORK adapter to use?

    I know it's something of an FAQ, but several hours spent on these forums and Google search gave me nothing of what works.

    All the solutions I've seen assume Windows as host and (something) as a guest.

    In my case, the host is Linux (CentOS 6.4) and invited is Windows XP.

    The host has two network cards, one on a 10.x.x.x network and the other on 192.168.x.x network.  In the guest virtual network adapter connects to the network 10.x.x.x.  I want it on 192.168.x.x network.

    I would be happy if I added another virtual network card and one of them connected to each network, but two of them connect to the 10.x.x.x network (with 10.x.x.x different IP numbers).

    The solutions I've seen indicate that under the Virtual Machine-> network adapter settings-> network connection, you click on the button "Configure the adapter" and load of come from there.  It would be great, but I have no button "Configure the adapter" or something like that.  I have a button "Advanced", but that just allows me traffic into and out of the butterfly and set a new MAC address, that's all.

    Because the host is Linux, I have also no equivalent to vmnetcfg.exe, at least none that I can find.

    So, where should I go from here?

    VMware Player is the version 6.0.0 (freshly upgraded 5.0.2 this afternoon).  I tried with version 5.0.2 and got the same thing.

    Thank you...

    You will need to use the virtual network Editor, although first you may need to create symbolic links.

    The first symbolic link already exist in a Terminal using the following command. Note: If connected a root the sudo command is not necessary when the.  Tip: Copy and paste the commands!

    ls-l/usr/lib/vmware/bin/vmware-netcfg

    If it exists, the output should be similar to the following.

    lrwxrwxrwx 1 root root 13 29 Sep 08:17 / usr/lib/vmware/bin/vmware - netcfg->/usr/lib/vmware/bin/appLoader

    At this point, you can simply use the following command to bring the virtual network Editor.

    sudo/usr/lib/vmware/bin/vmware-netcfg

    However, if you want easier access creates a symbolic link in: / usr/bin

    sudo ln-s/usr/lib/vmware/bin/vmware-netcfg/usr/bin/vmware-netcfg

    If the symbolic link/usr/bin/vmware-netcfg does not exist, then use the following command.

    sudo ln-s/usr/lib/vmware/bin/appLoader/usr/lib/vmware/bin/vmware-netcfg

    Then, to facilitate access to create a symbolic link in: / usr/bin

    sudo ln-s/usr/lib/vmware/bin/vmware-netcfg/usr/bin/vmware-netcfg

    To bring up the virtual network in a Terminal editor use the following command.

    sudo vmware-netcfg

    In the virtual network editor disable automatic bypass on vmnet0 by selecting the network map target in the bridge to: list box.

  • How can I move files and leave a shortcut.lnk pointing to the new location.

    I'm trying to move only a TON of old files to a hard drive to free up space to backup.  I can't empty just them, it's a working environment with integrated (and archaic) process.  They must be able to find the new files without go hunting for them.  How can I move all the files that has not been changed since 2 years and leaves a link behind that points to the new location?

    I used successfully a utility call NoClone.  The goal is to search for duplicate files, but it has a way to specify any search string (date function as you requested) and then move all files to a new location, leaving behind .lnk files

    I used it to clear space on file shares, any movement toward a archive read-only stored on a NAS that gets backed up once per year.  In this way, nothing changes on the NAS of the end user (no need to save often).  If you need to edit the file, they copy him on its original location.

    If you have a lot of files, download the business version.

    In recent years I finally used, so I don't know if there is a newer version that might not work as did the old version.

    I have a report R2, there a chart based on PivotTable. This report is called from another report R1 using the feature to the URL. Report R2 does not 'Print', 'Download' and 'back' link when it is called R1. But if I run R2 as it shows the report asandalone 'Print' and 'Download' links.

    can you pls suggest how I can get 'Print', 'Download' and 'back' links when R2 is called from R1 using the feature to the URL.

    You will usually use GO Url to integrate with external portal, so there is no value 'return' for the parameter 'Options '.

    The possible values for the link Options are:
    m change request
    f print version
    d - download to Excel
    r - refresh results

    If you need to view back, you can add another parameter called Done like below and provide the explicit path to where you want to go. For example, in the example below, I would go back to answers to myreport
