Can the IPS to block messages to the router?
Hi all!
An engineer told me that the IPS sensor can be configured to set up an ACL timed on a router based on alerts IPS he gets (to block a specific IP address for example). Is this true? I did a search but you can imagine all the results returned are for the IP configuration on the router (IOS IPS).
Can someone point me to a document or somewhere I can get more information?
Thank you very much!
Kind regards
Xavier
Xavier-
You were told correctly, that Cisco IPS sensors can create a temporary ACL in routers Cisco IOS and Cisco PIX / ASA firewall. The feature you're looking for is called 'Shunning' or 'Blocking'
You must enable fleeing to the signatures that you want to run and configure the IPS sensor with the necessary credentials, the interface and management on the router, you want the list ACL to appear.
Here is an example of a CLI configuration:
And here's an example configuration IME:

How can I activate the pop-up blocked message?
How can I activate the pop-up blocked message? When the message came I clicked on do not show this message again. I want this message to show when Firefox blocks a menu embedded, so I can allow the pop up if I want to.
You can see a pop-up block icon in the right corner of the status bar if you have chosen to hide the information bar at the top.
You can click on this icon of pop - up block on the status bar and remove the check mark [] «do not show an information message when pop-ups are blocked»

I activated the function 'block pop-up windows' in the menu Options/content of Firefox 21.0. When a message appeared telling me that the pop-up window a site had been blocked, I have chosen to "do not display this message" again.
Now, I want to turn on the "pop-up blocked" message. I don't know its place in the menu of Options or elsewhere to do. In previous versions of Firefox, there was once an icon in the status bar where I could re-enable the message of 'pop' - up blocked. Now that the status bar is gone, where I'm going to to reactivate?
When I test with disabled messages *, I have an icon in the URL bar (screen attached). What do you get?

Just moved LT from a device running on Win Vista (SP2) to the new device on 8.1 Win 64 bit
Installed last TB for this new device and registered the profiles.ini and profile data on Dorpbox
updated the new TB software on new device - profile folder and ini loading profile file'C:\Users\Martin\AppData\Local\Thunderbird\Profiles '.
'C:\Users\Martin\AppData\Roaming\Thunderbird\profiles.ini '.It loaded my old settings and I can now send and receive emails.
My question is:In the navihgation pane, everything is like in my last LT, but if I select a folder - it only shows me the configuration page and not the list of messages in the display pane. The only way to display these message is to click with the right button on the required folder and open it in a new tab or window. Then I can see a list of messages!
I read area online a lot to find my specific problem, but none related, please advise?
Thank you

I blocked some photos in facebook by accident, the toddler got click happy. How can I remove this block in some photos?
With Facebook on display, click the button to the site identity (for more details on what is, see https://support.mozilla.com/kb/Site+Identity+Button) and then on more information. This will open the page info dialog box.
First, select the permissions tab, make sure that 'Load the Images' is set to allow (default selection should work as well)
Then select the media tab, and then click the first item in the list. Use the down arrow key to scroll the list. If any element has the option 'Images of block of (field name)' selected, deselect the option.
This should hopefully solve your problem, but see also https://support.mozilla.com/kb/Images+or+animations+do+not+show
Some add-ons can also block images, for example, if you have AdBlock Plus installed, make sure that you have not accidentally created a filter to block images.

Having two computers laptops, wifi, windows7, and ie8. Your laptop, send and receive. Calendar and contacts works perfectly. Second computer, when you attempt to read emails via messenger or ie8, I get the above message, also calendar is not updated. If I connect directly to hotmail, bypassing ie8 and Messenger, everything is there, I guess it's a timing issue. Would appreciate any help. (worked fine until about 3 months ago)
