Disable/Change DoS Settings

I was wondering if it would be possible to disable or change the DoS settings on the CSS. At the moment, it is flagging valid hosts for a SYN attack and I'd like to either change the definition of "SYN attack" to a higher count than 10 packets or disable that feature alltogether. Any help would be greatly appreciated. Thanks.

Thanks for the response Gilles.
We've been looking at this and have started to zero in on the cause of the incomplete handshakes.
The issue we see now is that in our environment, there is no way to completely eliminate incomplete handshakes. Our hosts are connected over a private satellite network which is obviously sensitive to atmospheric attenuation. This being the case, there will always be the opportunity to have incomplete handshakes and the hosts will then be flagged for a SYN attack.
Here's some background on the issue. The sites that are on the CSS SYN Attack List either have been connected or will end up connecting after subsequent attempts. All of the sites have been connected and transacting with our server at one time or another so the routes are intact.
One of our technical requirements is that when a site connects, it needs to stay on the particular port and server for at least 24 hours. Any jumping from port to port is unacceptable which is exactly what we've seen from sites that have been flagged for SYN attacks.
I have a couple questions. First, how exactly does the CSS treat a host that has been flagged for a SYN attack? From what we've experienced, it seems that it reclaims all resources allocated for the site (FCBs) as well as removing it from the sticky table. If this is the case, is there any way to get the CSS to not drop the site from the sticky table so that it doesn't have the opportunity to connect to a different port/server on subsequent connection attemps?
Thanks in advance for any information.

  • How Do I Disable/Change Settings on My Scroll Wheel?

    I just downloaded Google SketchUp (a free drafting program) and I constantly need to "grip" the page to rotate and pan along my objects. This is done by clicking in on the scroll wheel and moving the mouse. On my Mac though (as opposed to the PCs at school) it pops up the dashboard screen every time I try this. So my question: How do I disable/change the default settings on my scroll wheel so I can use this program efficiently?
    -I never use the dashboard and can click the little icon if I need to, so keeping shortcut to that isn't an issue, I just want my scroll wheel back!

    I am either in the wrong location or have a different layout than you.
    Apple button > system preferences > keyboard and mouse > mouse tab > then all I have are the options to change the tracking speed, scrolling speed, double-click speed, and which button is required to zoom with the scroll wheel. The only drop-down menu I have on this screen is to select which button + scroll wheel allows me to zoom.
    I am using version 10.5.6. Am I in the incorrect section of this forum?

  • Are there any known issues with the epub plugin causing firefox to revert search engine back to yahoo and then disabling the ability to change search settings?

    My wife recently added a plugin, epub reader. Upon starting up Firefox the next day she noticed that the default search engine was changed back to Yahoo after we previously fixed this. Furthermore the ability to change search settings was grayed out. After epub reader was removed the problem was solved. I am surprised that I am unable to find anything written to this end about epub reader. Is this a tool promoted and distributed by Yahoo?
    Incidentally, how much would each user need to contribute to get mozilla away from Yahoo? Yahoo is, in my opinion, little more than an advertising vehicle, and not a real search engine.

    I went to Costco today and asked long known VZW Kiosk rep re what phone would he recommend...DX, DI or Fascinate.
    Not to my surprise, I was told that DX is the best of those three. Given the fact that all three is the same price $199, it indicates that is has nothing to do with price.
    When I acquired him about how Fascinate sales going, rep told me that since that phone went for sale this Thursday, local Costco only sold 10 Fascinate but that not all...7 of them were returned back to Costco by Saturday. That is a 70% return rate which seems to be way too high for the high level smartphone.
    At the same time, local Costo VZW kiosk can't keep up with demand of the DX, they are being sold out as soon as they are getting them. I am not advertising for DX here as I am myself briefly owned DX as soon as it was released and its problem with reboot forced me to return it as I didn't want to deal with replacement as I had bad experience in the past two years with VZW replacing my phones every two to three month with replacement phone being worse then the one that is being replaced.
    There is no such a thing as a perfect smartphone (sorry to all iPhone fans) but VZW should take a special "achievement" award for screwing up such a wonderful phone as Galaxy S.
    I can only hope that either DX with 2.2 will be better than the one with 2.1 or I will wait for what is coming up with HTC in November.

And it allllllll started with apples update to the ios7.... I HATED IT. Help.

    What your iPhone using friends label your phone number in their contacts is irrelevant. I don't know who you pay $9.99 a month to but it's not Apple. You can't disable text messaging on your iPad as it is not capable of SMS.
    Do you still have the iPhone? If so, log out of iMessage on the iPhone.

  • How can I change the settings in Safari to list the open windows chronologically instead of alphabetically?

    How can I change the settings in Safari to list the open windows chronologically instead of alphabetically?  I keep a lot of open windows e.g., 25 windows and many tabs on each) and like to work between a few at a time.  The problem is that Safari reorganizes windows alphabetically.  Once I open a new window, it take a while to find the windows I'm looking for.  Chrome and Firefox list the open windows chronologically which I find much easier.  The newest windows are at the bottom of the list.

  • Permanent Crash related to changing display settings while FCP is open.

    Recently, the display settings (arrangement) on my two monitors started changing by itself while I was working in FCP 6.5. I'm using ancient monitors (Viewsonic MB90 and Mitsubishi Diamond Pro 920. I just don't have the money to upgrade right now). Tis was annoying but I dealt with the problem by creating two different windows layouts. Then things got worse (the only thing I had done was install 8 gigs of additional memory on top of the original 2). FCP started crashing and now I can't even open the application. It doesn't react.
    Apple recently posted a not very informative acknowledgement of the problem with changing display settings while FCP is open, but it doesn't suggest solutions to my problem. It would be helpful to know a) what resolution and refresh rates are best for these old monitors and b)how to open FCP again. Your help is greatly appreciated.

    THIS IS IT!
    Disabling the nVidia deep colors for 3d applications solved the uber-annoying "flicker-screen-settings-and-disrupt/crash-other-programs" issue. I specifically only disabled deep colors for Premiere, not for all 3d applications I use, because none of them have caused the same problem as Premiere.
    This display-screen setting issue probably occurred because I use a Dell u3011 monitor which displays Adobe RGB color gamut, not just sRGB.
    However, now this brings up another question with disabling deep colors (effectively disabling the Adobe RGB use of the Dell monitor):
    QUESTION: If I have CG-rendered frames that seem to be created in sRGB and Adobe RGB (in two different programs), what color space should I be mixing/editing them in?
    I'm somewhat of a novice with the color spectrum/gamut issue. From what I understand, if I edit both CG images in sRGB, I'll be losing color data from the Adobe RGB-created CG image. If I edit both CG images in Adobe RGB, will I create minor banding effects on the sRGB image because it doesn't have the color range that I'm editing in? Perhaps my question is more relevant to AfterEffects compositing of the images rather than simply/only editing them in Premiere.
    The end result is something like an architectural film/ flythrough.
    Thanks,

  • I updated the kmp player a few days before. It changes some settings on my firefox

    I updated the kmp player a few days before. I believe that It changes some settings on my firefox or more.
    It changed my home page. Also, every time I reopen firefox, it cannot show my windows and tabs from last time.
    Then I removed or stopped using the plug-ins in firefox (one of them is npAPI) that installed that day, changed the setting back to what I want.
    I can then get the home page back, but the problem that I cannot get my previous tabs when I open firefox back still exists.
    I have updated firefox to 25.0 today.

    Hello,
    '''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
    ''(If you're not using it, switch to the Default theme.)''
    * On Windows you can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
    * On Mac you can open Firefox 4.0+ in Safe Mode by holding the '''option''' key while starting Firefox.
    * On Linux you can open Firefox 4.0+ in Safe Mode by quitting Firefox and then going to your Terminal and running: firefox -safe-mode (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
    * Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.

  • IE, Disable 'Automatically Detect Settings' Via GPO

    Hi guys,
    We have recently been having a small problem with IE, whereby the 'automatically detect settings' check box will get ticked - resulting in our users not being able to traverse our proxy server.
    I use the User Configuration > Policies > Windows Settings > IE Maintenance > Connection to set up our proxy settings, however I can't see an option to explicitly disable the 'automatically detect settings' check box.

  • How do I change system settings so that users are not required to enter the mac's admin pw in order to join a wifi network?

    how do I change system settings so that users are not required to enter the mac's admin pw in order to join a wifi network?
    Right now my macbook pro requires an admin password before connecting to a new wifi network. In other words when a user that is not an admin tries to connect to a new wifi network the pop up displays indicating that it is locked and an admin password is required.
    Is there a way to remove this restriction so that a non admin can connect to wifi without the mac's admin password.

    You can enable / disable this option in System Preferences:
    System Preferences > Network > Wi-Fi > Advanced > Wi-Fi tab > Require administrator authorization to: Change networks

  • Changed Security settings, now cannot connect

    Hi,
    I was trying to increase my security settings on my WRT54G v. 8 and somehow have messed up my connection. I updated the MAC settings so that only my computer has access, and I tried to change my WEP from 64 to 128 bit. I now realize I should just change it to WPA, since it is much more secure. Now my wireless is not working, saying limited or no connectivity because it couldn't assign a network address, I believe (It looks like I don't have an IP address??). When I use my wired internet and type in the default wireless IP address, it says that the connection is not valid or some such thing (sorry, I am not on my home computer now) and I cannot get in to change the settings again. Do I need to reset the router and reset all my settings? How can I reconcile new security settings with my computer? Thanks!

    To set up wireless security, you must use a computer that is wired to the router.
    Where to find the router settings: The router's login password is usually on one of the "Administration" pages. The other settings are all found in the "Wireless" or the "Security" section of the router's setup pages, located at 192.168.1.1
    First, give your router a unique SSID. Don't use "linksys".
    Make sure "SSID Broadcast" is set to "enabled".
    Next, leave the router at its default wireless settings (except for the unique SSID), and then use your pc to connect wirelessly to the router. Test your wireless Internet connection and make sure it is working correctly. You must have a properly working wireless connection before setting up wireless security.
    To implement wireless security, you need to do one step at a time, then verify that you can still connect your wireless computer to the router.
    Next, encrypt your wireless system using the highest level of encryption that all of your wireless devices will support. Common encryption methods are:
    WEP - poor (see note below)
    WPA (sometimes called PSK, or WPA with TKIP) - good
    WPA2 (sometimes called PSK2, or WPA with AES) - best
    WPA and WPA2 sometimes come in versions of "personal" and "enterprise". Most home users should use "personal". Also, if you have a choice between AES and TKIP, and your wireless equipment is capable of both, choose AES. With any encryption method, you will need to supply a key (sometimes called a "password" ).
    The wireless devices (computers, printers, etc.) that you have will need to be set up with the SSID, encryption method, and key that matches what you entered in the router.
    Retest your system and verify that your wireless Internet connection is still working correctly.
    If you have trouble connecting, in the computer, go to your wireless software, and go to "Preferred Networks" (sometimes called "Profiles" ). There are probably a few networks listed. Delete any network named "linksys". Also delete any network that you do not recognize, or that you no longer use.  Delete your current network (this will remove any old settings).  Reboot computer.  Return to "Preferred Networks" and re-enter your current network info (SSID, encryption (if any), and key (if any) ). Then select your current network and make it your default network, and set it to automatic login. You may need to go to "settings" to do this, or you may need to right click on your network and select "Properties" or "settings".  Reboot computer.  You should reconnect automatically (it can take up to two minutes).  If you still have trouble, temporarily turn off your computer software firewall.
    And don't forget to give your router a new login password.
    Picking Passwords (keys): You should never use a dictionary word as a password. If you use a dictionary word as a password, even WPA2 can be cracked in a few minutes. When you pick your login password and encryption key (or password or passphrase) you should use a random combination of capital letters, small letters, and numbers, but no spaces. A login password, should be 12 characters or more. WPA and WPA2 passwords should be at least 24 characters. Note: Your key, password, or passphrase must not have any spaces in it.
    Most home users should have their routers set so that "remote management" of the router is disabled. If you must have this option enabled, then your login password must be increased to a minumum of 24 random characters.
    One additional issue is that Windows XP requires a patch to run WPA2. The patch is located in SP3, so you will need SP3 to run WPA2 in Win XP. Vista already supports WPA2.
    Note:
    WEP is no longer recommended. The FBI has demonstrated that WEP can be cracked in just a few minutes using software tools that are readily available over the Internet. Even a long random character password will not protect you with WEP. You should be using WPA or preferably WPA2 encryption.

    Try the following:

    Go to Settings > General > Reset > Reset Network Settings
    let it do it's thing and reset.
    Then go to Settings > Messages > iMessages > enable
    You'll then have to go back to your Wifi and re-enter your router credentials.

  • Changing BIOS settings?

    About a month ago I picked this motherboard up, and I usually format after I get new hardware. Since this new motherboard apparently doesn't let me change them, and WinXP doesn't have DOS, how do I change my BIOS settings so I can format?

    I'm sorry.. You've totally lost me.
    ...you can't get into BIOS?
    ...or you can't boot to a Windows CD?
    ...or are you talking about BIOS update protection?
    I'm confused.
    me_AMD is right, though... if you want to change BIOS settings just press DELETE on your keyboard, whether PS/2 or USB makes no difference. Press it as soon as the video card bios disappears and the system posts.
