I'll have a check point asking me to disable or delete the policy by default ISAKMP on my router. I tried to do, but I got an error that the command is not supported as below:

  • How to remove the default isakmp on a ciso router strategy (3845)

    Hi all. My company recently failed a PCI scanning as our router returned the 56-bit encryption for negotiation isakmp on an existing default isakmp policy. How can I remove this default isakmp policy. I'm not under 12.4 (15) T1 so no crypto isakmp default policy does not work. Is there one way other than the upgrade of the IOS? Any suggestions?

    Is it possible to configure a maximum number of isakmp policy authenticating a router checks? I have 2 strategies more priority configured ISAKMP. Perhaps if there is an order to limit the number of policies isakmp router checks, it would eliminate this default policy with?

    Y at - there no way to disable or change the default ISAKMP policy?  I created the number 20 of the police, which is used in a VPN site-to site in vain for a quarterly PCI analysis the results come back in due to stage successful 1 authentication with encryption DES/DH768.  I reproduce these results with the help of ike-scan with explicit parameters OF/DH768.

    This is a 2600 router and I just upgraded to 12.4 IOS (23) because I came across (http://www.cisco.com/en/US/docs/ios/security/command/reference/sec_c4.html) Cisco documentation which says that 12.4 (20) introduced the "no crypto isakmp default policy" - but I do not see this command still available to me.  Here are the results of sh crypto isakmp policy:

    Hello Anthony,.

    I saw the link you provided.  It seems that this command was introduced in12.4 (20), T... note the T.  This indicates that it is only in the T-train train or technology and only seen in some other 12.4 T code or the train from 15.x newert.

    You say that your router is runnign 12.4 (23) implicitly code Mainline (M).

    The last T code for 2600 seems to be a 12.4 (15) T, so it does seem that you can enable this feature in order to disable the default policies.  It also seems that the 2600 series retired as no new code is released March 27, 2010.

    http://www.Cisco.com/en/us/products/HW/routers/ps259/prod_eol_notices_list.html

    Looks like you can be out of luck and may need to look for in buying a newer model router to get the newest software support and the ability to disable the default isakmp suite.

    Of course, it is noted that while they can establish a session ISKMP, however, they will really be authenticated by the router in message MM 5 as most people use internal cases for certificates on the VPN.

    I hope this helps.

    You cannot disable the default Gmail account.  It is obligatory on the phone.  However, you can turn off notifications in the Gmail app.  That should eliminate the second notification.  Open the Gmail app and press Menu-> settings and uncheck the box to mail notifications.  This should take care of your problem.  I hope this helps.

  • How to set the default value of the FF browser offline mode? I WANT IT IN OFFLINE MODE *.

    I wish that my FF browser opens in offline mode. There is a ton of help topics on how to disable the default offline, but none on how to activate it. I tried to do the opposite of what people suggested to turn off offline mode, but nothing seems to work.

    Thanks adavance for any help!

    The only way to start Firefox in offline mode is through the start of the Profile Manager window.

    This window contains a checkbox to start in offline mode.

    All other methods via prefs may or may not work reliable and extensions usually do the opposite and are trying to force a boot online.

  • 11g: how to disable the ToolTip for gauge?

    Hello

    DVT:graph and dvt: gauge (type = LED) displays a ToolTip by default when you move the mouse over the series or leads.

    With dvt:graph you can set the property markertooltiptype to "MTT_NONE" in order to avoid this default ToolTip.
    For dvt: gauge, I can't find such a possibility.

    How to disable the default ToolTip for dvt: gauge too?

    Jdev 11.1.1.0.2

    concerning
    Peter

    Hi Peter,.

    For a gauge, the best way to turn off the ToolTips is to use the attribute renderImagemap with imageFormat = "PNG". For example:

    If instead, you decide to customize the ToolTips of the gauge, you can use the alt attribute to shapeAttributes (without the renderImagemap = 'false'):

  • How to disable the App tabs (tablets should) start automatically?

    How to disable the App tabs (tablets should) start automatically?

    because the option [don't load the tabs up to choosing] dose does not work with her, and she keeps starts every time when I restart Firefox.

    Please help me!

    Don't bother, I arrived at the solution of my car, you can do the following:

    Type "subject: config" [without quotes!] in the location Bar (address bar) and press ENTER to display the list of preferences, as shown in the photo #1 in Firefox 17 under Windows 7.

    If you see a page with the warning as pictured #2, this might void your warranty!, click the "I'll be careful, I promise!" button to continue (in fact, there is no guarantee that it is, it's more a joke to ensure that users are aware of what they are about to do). Uncheck the box to avoid the warning in the future.

    Now to the search bar in the image #3 type: tab and search for it

    preference name:
    

    Browser.sessionstore.restore_pinned_tabs_on_demand

    or you can copy directly to the search bar.
    Then, follow the instructions in the photo n ° 3 .

    Just in case where if the photo appears, follow these steps:

    First: Right-click on the name of the preference that we sought.
    Then, click Toggle to change the value from false to true.
    Or, double-click it and it will change.
    Finally, restart Firefox, and you'll notice that they don't automatically load until you click on it.

    That's it, good luck to all. ;-)

    Note: the list of fonts preferences fat is the user changed, and the United Nations-fat is the default setting.

    Warning: change preferences can, in rare circumstances, break Firefox, Thunderbird or Mozilla Suite, or cause strange behavior. Only do if you know what you're doing or trustworthy tips.

    Additional INFORMATION:

    Subject: config is a feature of Mozilla applications which lists application settings (known as preferences) that are read from the profile files prefs.js and user.js and the default application. A lot of these preferences are not present in the preferences or Options dialog box. Using about: config is one of the many methods of changing the preferences and adding the other 'hidden '.

  • 5102na HP OMEN: how to disable the audio correction Bang & Olufsen horrible?

    Is there someone who could tell me please how to disable the audio correction Bang & Olufsen? I'm sure that some people like it but I work with audio and I can't really how it changes the sound. I tried to open the Bang & Olufsen sign but I cannot unselect the correction in the section "listening experience", nor that I can change the associated equalization. Please someone help, thanks!

    I found a solution: http://h30434.www3.hp.com/t5/Notebook-PC-Sound-and-Audio/Beats-Audio-compression-and-volume-fluctuation-HP-ENVY-m6/m-p/5137867/highlight/true#M67144

    1. Go to the Windows Device Manager > sound, video and game controllers section.
    2. In the list of the audio device drivers, look for Realtek High Definition Audio. This is the device driver for BeatsAudio (a bit sneaky, wouldn't you say?).
    3. Right-click and select disable. Down arrow on this driver, indicating it is disabled. (NOTE: at this point, you will not be able to play music files.)
    4. Right click and select Update driver software.
    5. Select Browse my computer for driver software.
    6. Select Let me pick from a list of drivers for devices on my computer.
    7. You should see a window that says Select the driver to install for this hardware device. NOTE: If you see a window that says something like This is the best driver for this device, close the window and repeat steps 4, 5 and 6.
    8. In the scheme box, select Audio device high definition (this is the device driver audio substitute) and click Next.
    9. In the Update driver warning window, click Yes. You should see a confirmation with the high definition Audio Device display window. Click on Close.
    10. In the list of drivers of audio device in the section audio, video and game controllers, you will notice that the high definition Audio device now displays instead ofHigh Definition Audio Realtek.
    11. When prompted to restart, click Yes.

    This does not disable audio-Bang & Olufsen, but I just installed this EQ across the system instead: http://sourceforge.net/projects/equalizerapo/

    HP needs to release a driver which allow us access to the "Improvements" tab so we can turn off "Loudness equalization" (although "Loudness equalization" should not be on by default in the first place).

    The current driver is default.
