Ports that suddenly appears as closed when they are open.

Hi all

I've recently set up a server on 10.11. I use the Profile Manager and form VPN outside the network.

I have forwarded all ports required and that everything worked well and then a week later Profile Manager stopped appearing in the section "reachable." I checked the ports with canyouseeme.org and was reported as "closed". They are open on the firewall.

Then a week later VPN went from "reachable."

I ran a few packet capture and found that the traffic was in the local network and rejected by the server.

Can anyone think of any suggestions on why the traffic is rejected?

Thank you.

Services are available inside the network?

  • Is it possible to create a folder that can hide files automatically, when they are copied in it?

    Hello!!!

    Is it possible to create a folder that can hide files automatically, when they are copied in it? I mean how to program a folder so that everything that he would automatically become hidden? I would be very grateful...

    Is it possible to create a folder that can hide files automatically, when they are copied in it?

    Yes. A sort of roundabout.

    For this example, create a folder on your C drive named HideTest.

    Download http://winsupport.org/utilities/freedos-choice.html Choice.Exe (click on the link to download the utility program near the bottom of the page. "And save it in the C:\HideTest folder).

    Open Notepad and then copy and paste the following text in it:

    Off @Echo

    : All
    Set FilesToHide = No.

    : GoToDir
    C:
    cd\HideTest

    : Top
    CLS
    IF FilesToHide %! Is Yes! Attrib *. * + H

    : Choice
    Choice.Exe /c:YN t:Y, 30 are looking for files to hide
    If ErrorLevel 2 Goto: exit

    : MakeList
    Dir > TempList.Txt

    : CheckFiles
    Set FilesToHide = No.
    Find.Exe "0 file (s)' TempList.Txt
    If ErrorLevel 1 Set FilesToHide = Yes
    If exist TempList.Txt Del TempList.Txt

    : Loop
    Goto: Top

    : Output
    Set FilesToHide =
    If exist TempList.Txt Del TempList.Txt
    Output

    Click on file, then save under...

    Go to C:\HideTest

    Name the file Hide.Bat

    Click Save

    Close Notepad

    Open Windows Explorer

    Go to C:\Documents and Settings\UserName\Start where user_name is your own username.

    In the right pane, right click, select New, and then click shortcut.

    Click Browse, and then navigate to C:\HideTest and click on Hide.Bat, click Next.

    Type a new name or accept the default name and click Finish.

    Right-click on the newly created shortcut, and click Properties.

    Change the race: from the normal window to reduced.

    Click on apply, and then click Ok.

    Restart your computer.

    Note: In the line above Choice.Exe c:YN t:Y, 30 are looking for files to hide, 30 is the number of seconds it will wait before checking the new files. This can be from 1 to 99.

    Edit: Just to satisfy my curiosity, why do you do this?

  • I need my files to open in the monitor # 2 I usually have some important information about the number of monitor 1. I need the files to alternate when they are open. One in 2, then one 1.

    I need my files to open in the monitor # 2 I usually have some important information about the number of monitor 1. I need the files to alternate when they are open. One in 2, then one 1.

    Kind regards

    How it works is usually the application (explorer.exe is an application) in question is open about everything that monitor his last (final) session was closed the.  Not all applications have this built-in memory, but most do.

    I don't think that even something TO manage multiple monitors (this is what it was built for) will do what you are wanting.  ;-)  I see no way of programming of this type of automation.  ;-)

    Can move you to a new Windows 7 computer

    If it's a full license or upgrade retail - Yes. You can move it to another computer as long as it is installed on a single computer at a time (and if it's a Windows 7 Upgrade version the new computer must have its own XP/Vista license qualification). The previous installation of Windows 7 on the old computer must be formatted or deleted. You will have to perhaps call Microsoft and explain what happened to complete activation. Turning it on the second computer will automatically be in effect 'disable' the license for the first computer. The key works with 32 and 64 bit, but can only be installed at a time.

    If it's an OEM license - don't. OEM licenses, including Windows preinstalled on a computer before purchase and Windows purchased separately, are related to the first computer, they are installed on and cannot be transferred to another computer. To install Windows on another computer, you will need to buy another copy.

  • EliteBook 8740w thinks that the lid is closed, but it is open?

    Hello

    I have an EliteBook 8740w running Windows 7 64 bit and I have a strange problem where the laptop seems to think that the cover is closed when it is open.

    If the cover is open, the screen is off the touchpad and keyboard, the two do not work and not the function of the buttons volume or wifi. When the screen is almost completely closed the screen turns back on, the keyboard and the mouse are beginning to work again, but it is not usable, because it is about 5 degrees, far from fully closed.

    It seems that it is just reverse how it is supposed to work?

    All this happened when I unplugged my power cord. The screen turned white and it has been in place since then. I tried several reboots, nothing seems to recover.

    I can run on my external monitor very well, so the laptop seems to be otherwise functional

    Thanks in advance for any ideas

    Maybe you did not reset properly.

    Remove the battery and adapter and all the things connected to the laptop.

    Hold the power button down for 1 full minute and only plug the adapter back to (do not insert the battery) and start.

    The next time you stop everything, install the battery.

    How to stop messages from Skype that suddenly appears on my screen when other people use my computer?  using windows 8, but I can't control these messages (sometimes very) distracting to appear?

    Hello

    If you are allowing others to use the computer, set up a new account for each user.  They would then not be able to display your desktop or Skype messages.

  • Channels in the Panel layers appear reversed when they are not

    My layers in Photoshop CC Panel have suddenly started to display all reverse channels, when they are selected and reused for example in the form of mask in the layers panel, they appear correctly. Maybe I've changed inadvertently in some settings to make this odd behavior, but I really want that back in a useful way. Any ideas appreciated. Below you can see a screen shot of how the alpha even looks in the channels of the panels and layers.

  • How is it, I don't see any of my themes of appearance, even when they are turned on?

    I don't see one of my themes of appearance, even when they are activated. I tried deactivating and reactivating them and gone through all my themes, but none show except the default 20.0.01; which when I try other themes shows even when it is disabled.
    Also, I don't see any new themes when I try to preview them or hover over with the mouse.

    Sorry, but if you start automatically to the top in private browsing mode, this is a bug that has been tracked and should be corrected in the next version of Firefox. More information: themes, not more function from auto update to firefox 20.

  • I had to rebuild the computer and reinstalled the photos of cecently.  I have photos imported into Lightroom, but the parameters associated with the photos, that is to say. When they were developed, are not there.  How to import these?

    I recently had to rebuild the computer and reinstalled the photos.  I have photos imported into Lightroom, but the parameters associated with the photos, that is to say. When they were developed, are not there.  How to import these?

    Default LR stores all changes in the catalog file, not in the pictures. So if you have a backup of your original catalog you will need to copy on the newly rebuilt system and open it in LR. You will then need to recreate a link to the images in the catalog depending on where are your images and where the original LR catalogue think they are.

  • Kensington Trackballworks sometimes has several icons in the tray system, exposed behavior, it is as if one or more mouse buttons are kept pressed when they are in fact not to be affected

    Original title: Kensington Trackballworks sometimes has several icons in the system tray

    Every so often from the start (no apparent reason) multiple Kensington TrackallWorks icons appear in the system tray and the unit behaves erratically until all but one of them are closed. Behavior exhibited, it is as if one or more mouse buttons are kept pressed when they are in fact not to be affected. I use a Kensington Expert Mouse and TrackballWorks 1.04 K64325 model number. Uninstall and reinstall the driver didn't help, or does uninstalling and reinstalling Windows.

    I checked with MSCONFIG, Autoruns and even when several copies work they show only one entry for the application. Any ideas /.

    Hello
     
    Since you've already tried to uninstall and reinstall the driver/windows, this could be a hardware problem. Please try to contact the manufacturer of the mouse for assistance on this issue.

  • Help! Photoshop edited jpg color false when they are imported into Muse

    Okay, so I try to build a Web page of photography (among others) and I change most of my photos in photoshop. All the photos I edit in photoshop and save it in jpg format, look great when printed, uploaded on facebook etc, but when I import them into Adobe Muse for and put them on my page Web, the colors of the photos becomes desatures or distort slightly (so that they appear dull). When I edit images in lightroom and save them in jpg format and import them into Muse, they look fine, but colours edited in photoshop seem to spoil my pictures when they are imported into Muse.

    What I am doing wrong?

    You are using some weird color management settings and do not convert to sRGB probably... Check your settings in PS itself and save for Web dialogue box and experiment around.
