  • What is relationship between ping and tcp in BGP ?

    Dear All, As we know, BGP peer relation needs reachability  of tcp 179. But usually if the two peer neighbors can ping each other, we can consider the tcp 179 is working well. So what is relationship between ping and tcp in BGP in this situation ? Thank you !

    Ping is a tool in the ICMP suite, and doesn't use ports. It uses codes.  TCP is a different protocol, and does use ports.  In the case of BGP, once the process is started (and you have at least one neighbor command) it will open port 179.  Who is the client and who is the server in the neighborship, does not matter.  If you have issues with BGP neighbors being formed, and you believe the configuration is correct - Telnet to the port to be sure that it is working.  Also, if they are not directly connected, you may need to enable multihop.  Check Access lists also.
    Pinging the other router it is unrelated to the BGP TCP process. - Here is an example pinging fine, but before the BGP process has opened port 179.
    There is just two routers on a /30 segment - 10.19.2.2 and 10.19.2.1
    LON-ROUTER#ping 10.19.2.1      
    Type escape sequence to abort.
    Sending 5, 100-byte ICMP Echos to 10.19.2.1, timeout is 2 seconds:
    Success rate is 80 percent (4/5), round-trip min/avg/max = 8/9/12 ms
    Pings fine.
    LON-ROUTER#
    LON-ROUTER#telnet 10.19.2.1 179
    Trying 10.19.2.1, 179 ... 
    % Connection refused by remote host
    Enable BGP on the neighbor:
    LON-CORE(config)#router bgp 65000
    LON-CORE(config-router)#neighbor 10.19.2.2 remote-as 65001   
    LON-CORE(config-router)#
    try the TCP connection again
    LON-ROUTER#
    LON-ROUTER#telnet 10.19.2.1 179
    Trying 10.19.2.1, 179 ... Open
    The connection now works, as the port is open on the neighbor.

  • Signature 1330-X: TCP segment out of order - what does it mean?

    Hi,
    on a customer's site, on one of their IPS, I get a lot of sig 1330 alerts, mainly those two:
    1330-12: TCP segment is out of order. If the signature status is set to disabled, the packet will be passed to all engines that are not stream based.
    This signature will not produce an alert in promiscuous mode regardless of the signature status.
    1330-17: TCP segment out of state order. If a packet in a stream causes this signature to produce an alert, processing will cease for that stream. This signature will not produce an alert in promiscuous mode regardless of the signature status
    I'm not sure how to interpret these alerts correctly and/or how to troubleshoot further. Does anyone have an idea?
    Thanks a lot,
    Florian

    Is your sensor monitoring more than one network segment?
    If so then these alarms are common when a TCP connection crosses both networks and gets seen twice by the sensor.
    This can confuse the sensor's tracking of the connection.
    A common scenario is to have the sensor monitor both the Inside network or a firewall as well as the DMZ. When an internal user connects to the company's web server the traffic gets seen by the sensor both on the Inside network and in the DMZ. The sensor tries to put the packets from both networks together in order to try and monitor it as a single connection. Because the packets get modified by the firewall it often results in inconsitency between traffic on the 2 sides and causes the sensor to be confused about the connection.
    The good news is that if this is your problem, then there are 2 easy workarounds.
    1) If your sensor supports virtual sensors, then create a second virtual sensor. Assign one network to default vs0, and assign the other network to the new virtual sensor. This way each virtual sensor sees traffic on just one of the networks and won't become confused.
    2) If your sensor does not support additional virtual sensors, or you've used up all 4 virtual sensors, then there is a configuration option within the virtual sensor configuration itself:
    Inline TCP Session Tracking Mode
    By default it is set to Virtual Sensor which is why it tries to put together packets from both networks to try and look at is a single connection and gets confused.
    BUT it can also be set to Interface and Vlan. This configuration allows the virtual sensor to treat the traffic on each network independantly. The connection on the first network will be monitored independant of the connection on the second network. This will prevent the virtual sensor from getting confused.
    The above is just my guess at what is going on in your network based on what we've seen on other networks. If this doesn't address the reason for the signature triggerings, then please respond back with more information about your network.
    It is possible that these could be a hacker trying to avoid detection by the sensor, but more likely something in your deployment is confusing the sensor.

  • Css11501 Whats the difference in persistence and stickiness

    css11501 Whats the difference in persistence and stickiness

    persistence is an HTTP concept.
    With HTTP 1.1 you can now have 1 TCP connection for all your HTTP requests.
    With this solution you reduce time by not having to open and close TCP connections for every request.
    It is sometimes needed to break persistence to guarantee a better load sharing between the servers.
    This is the case when multiplie users use the same proxy server.
    The proxy would generally open a persistent connection and use it for all the requests from all the users.
    Stickyness is a loadbalancing mechanism to guarantee that every TCP connections are sent to the same server.
    You can do stickyness based on source ip, or SSLID, or a cookie, or ...
    Stickyness is required when you have a website saving information about a user session [ie: a shopping basket].

  • TCP packet out of state: First packet isn't SYN & Outlook is trying to retrieve data from the Microsoft Exchange Server [CAS-ARray]

    We are transitioning from Exchange 2003 to Exchange 2010.  We found Outlook online mode (non-cached mode) have many warning "Outlook is trying to retrieve data from the Microsoft Exchange Server [CAS-ARray]", usually happen when users tried to open
    address book but sometimes even normal operation like click the Send button.  The problem does not affect OWA and extremely rare when Outlook is running in cached mode.  Check the firewall logs, we notice a lot of "TCP Packet Out of State" drops.
    We have a lot from the CAS/HT to DC/GC on TCP_3268 and LDAP.  And the errors are "TCP packet out of state: First packet isn't SYN" with tcp_flags FIN-ACK, PUSH-ACK.
    We also have a lot from CAS/HT to the Outlook Clients on the static RPC port (TCP_59933).   And the errors are "TCP packet out of state: First packet isn't SYN" with tcp_flags FIN-ACK, PUSH-ACK and RST-ACK, ACK.
    This happens even on Outlook 2010 which I though it has TCP Keep Alive implmented to keep the session active within 1 hour. 
    Can somebody tell me if these out-of-state are the cause of our problem?  And how to fix it?
    THANK 1,000,000

    Hello AndyHWC,
    I did some consulting with our CAS team and received the following feedback to your post:
    It is difficult to determine what is causing resets without seeing the captures first hand however, the concern is that you are seeing dropped packets on the firewall logs.  Where is this firewall located?
    Based on the description "Check the firewall logs, we notice a lot of "TCP Packet Out of State" drops." and "We have a lot from the CAS/HT to DC/GC on TCP_3268 and
    LDAP." indicates to me that the firewall is between CAS and GC.  This not supported under any circumstances and would explain the issue they are seeing with clients trying to "retrieve data from the GC".
    If there is not a firewall between the GC and CAS then a Microsoft support engineer would need to have concurrent Netmon Captures from client, CAS, GC during the
    issue to analyze.  If only one GC exists consider adding another GC to handle the client requests and for fault tolerance.
    Also verify that all NIC card drivers are updated to the latest driver version

  • I've just found that three movies I've bought from iTunes on on my iPad are not showing up on Apple TV or anywhere other than that iPad.  What's up with that and will I lose these films if I reset this iPad?

    I've just found that three movies I've bought from iTunes on on my iPad are not showing up on Apple TV or anywhere other than that iPad.  What's up with that and will I lose these films if I reset this iPad?

    Thanks.  The reason this has become an issue is that I recently bought a new Macbook Air that the iPad is not synced to.  The one is was synced to was stolen.  If I want to sync this iPad to the new Air, won't it be wiped before I'm able to copy these films or am I wrong about that?

  • FAQ: What features use the GPU and how do I troubleshoot GPU issues?

    Photoshop CS6 GPU FAQ
    Introduction
    This document provides a quick reference guide to video card usage in Photoshop.  Some features require a compatible video card to work; if the video card or its driver is defective or unsupported, those features will not work at all.  Other features use the video card for acceleration and if the card or driver is defective those features will run more slowly.
    Mercury Graphics Engine
    The Mercury Graphics Engine (MGE) represents features that use video card, or GPU, acceleration. In Photoshop CS6, this new engine delivers near-instant results when editing with key tools such as Liquify, Warp, Lighting Effects and the Oil Paint filter. The new MGE delivers unprecedented responsiveness for a fluid feel as you work.
    MGE is new to Photoshop CS6, and uses both the OpenGL and OpenCL frameworks. It does not use the proprietary CUDA framework from nVidia.
    In order to use MGE, you must have a supported video card and updated driver. If you do not have a supported card, performance will be degraded. In most cases the acceleration is lost and the feature runs in the normal CPU mode. However, there are some features that will not work without a supported video card.
    GPU features added in Photoshop CS6
    Adaptive Wide Angle Filter (compatible video card required)
    Liquify (accelerated by compatible video card with 512MB VRAM, GPU mode unavailable on Windows XP)
    Oil Paint (compatible video card required)
    Warp and Puppet Warp (accelerated by compatible video card, GPU mode unavailable on Windows XP)
    Field Blur, Iris Blur, and Tilt/Shift (accelerated by compatible video
    card supporting OpenCL, GPU mode unavailable on Windows XP)
    Lighting Effects Gallery (compatible video card required with 512MB
    VRAM, unavailable on Windows XP)
    New 3D enhancements (3D features in Photoshop require a compatible video card with 512MB VRAM, unavailable on Windows XP):
    Draggable Shadows
    Ground plane reflections
    Roughness
    On-canvas UI controls
    Ground plane
    Liqht widgets on edge of canvas
    IBL (image based light) controller
    * Note that all 3D features are unavailable on Windows XP in Photoshop CS6

    GPU/OpenGL preferences in Photoshop CS6
    The advantages of using a compatible video card (GPU) with Photoshop are that you can experience better performance and more features.   Problems can occur if you have an older video card with limited VRAM or if you use other programs at the same time as Photoshop that use the GPU.
    Choose Edit > Preferences (Windows) or Photoshop > Preferences (Mac OS).
    In the Performance panel, make sure Use Graphics Processor is selected in GPU Settings.
    Click Advanced Settings and specify the following options:
    Mode > Basic
    Mode > Normal
    Mode > Advanced Provides the benefits of Normal mode as well as newer OpenGL advances that can result in improved performance.
    Use Graphics Processor to Accelerate Computation
    Use OpenCL Uses the GPU to accelerate the new blur filters (Field Blur, Iris Blur, and Tilt-Shift) – OpenCL will only be available on newer GPUs that support OpenCL v1.1 or higher
    Anti-Alias Guides And Paths Allows the GPU hardware to smooth the edges of drawn guides and paths.
    30 Bit Display (Windows only) Allows Photoshop to display 30 bit data directly to screen on video cards that support it
    Quick GPU Troubleshooting Steps
    You can experience problems such as artifacts, errors, and crashes if there are incompatibilities between Photoshop and the display components that access the GPU.
    If you experience crashes, incorrectly rendered windows or objects, redraw issues, or performance issues while running Photoshop, first determine whether OpenGL is causing the problem.
    Turn off OpenGL.
    Choose Edit > Preferences (Windows) or Photoshop > Preferences (Mac OS).
    In the Performance panel, uncheck Use Graphics Processor. Click OK.
    Restart Photoshop, and perform the same function.
    If the problem recurs while OpenGL Drawing is disabled, OpenGL is not the cause. For additional troubleshooting, see Troubleshoot system errors and freezes | Adobe software on Windows (cpsid_82252) or Troubleshoot system errors and freezes | Adobe software on Mac OS 10.x (cpsid_82414).
    If the problem resolves, proceed with the rest of the troubleshooting steps to fix OpenGL.
    Make sure that you're using the latest update of Photoshop.Updates fix bugs and issues.
    Update the display driver.Updated display drivers can fix many issues, such as crashing, incorrectly rendered objects, and performance problems. Determine what video card you have and go directly to the manufacturer's website (nVidia or ATI/AMD) and download the latest driver. (Note: Simply doing a Windows Update is does not guarantee you are using the latest driver. You must go directly to the nVideo or ATI/AMD websites to get the absolute latest driver.) After you update your driver, turn on Use Graphics Processor in Photoshop preferences.
    Reset preferences.
    Resetting preferences returns OpenGL settings to their default status. Reset Photoshop preferences by pressing and holding Shift+Ctrl+Alt (Windows) or Shift+Option+Command (Mac OS) immediately after you start Photoshop.
    Click Yes when asked if you want to delete the Adobe Photoshop Settings File.
    Retry the function that caused the problem.
    Change the OpenGL mode to Basic.
    Setting the OpenGL mode to Basic uses the least amount of GPU memory and the most basic GPU feature set.
    Close all documents.
    Choose Edit > Preferences (Windows) or Photoshop > Preferences (Mac OS)
    In the Performance panel, click the GPU Settings Advanced Settings button.
    Choose Mode > Basic
    Restart Photoshop.
    If this solution resolves the problem, switch to Normal mode. See if the issue recurs. If the issue recurs, return to Basic mode.
    Note:  If you’re changing GPU preferences to troubleshoot a problem, re-launch Photoshop after each change.
    If you are using more than one video adapter, remove the additional cards.
    Multiple video adapters can cause problems with GPU accelerated or enabled features in Photoshop. It's best to connect two (or more) monitors into one video adapter. If you have to use more than one video adapter, make sure that they are the same make and model. Otherwise, crashes and other problems can occur in Photoshop.
    Note: Using two video adapters does not enhance Photoshop's performance.
    Check your Cache Levels setting.
    If you've set your Cache Levels to 1 in Photoshop preferences, you can experience performance issues with GPU features. Reset Cache Levels to the default setting, which is 4.
    Choose Edit > Preferences > Performance (Windows) or Photoshop > Preferences (Mac OS)
    In the Performance panel, choose Cache Levels > 4.
    The GPU Sniffer
    To help guard against Photoshop crashes related to bad GPU hardware or drivers, Photoshop employs a small program called the GPU Sniffer. Every time Photoshop is launched, Photoshop launches the sniffer. The sniffer runs rudimentary tests of the GPU and reports the results to Photoshop. If the sniffer crashes or reports a failure status to Photoshop, Photoshop will not use the GPU. The Use Graphics Hardware checkbox in the Performance panel of the Preferences will be unchecked and disabled.
    The first time the sniffer fails, Photoshop will display a dialog indicating that it has detected a problem with the GPU. On subsequent launches the dialog will not appear unless the Photoshop preferences are reset.
    If the user corrects the problem, either by replacing the video card or by updating the driver, then the sniffer will pass on the next launch and the Use Graphics Hardware checkbox will be enabled and returned to its previous state (enabled or disabled).
    Tested video cards for Photoshop CS6
    Adobe tested the following video cards before the release of Photoshop CS6. This document lists the video card by series. While the minimum amount of VRAM supported on video cards for Photoshop CS6 is 256MB, some features require 512MB of VRAM to be enabled.
    Note: Adobe tested laptop and desktop versions of the following cards. Be sure to download the latest driver for your specific model. (Laptop and desktop versions have slightly different names.)
    nVidia GeForce 8000, 9000, 100, 200, 300, 400, 500 series 
    nVidia Quadro 400, 600, 2000, 4000 (Mac & Win), CX, 5000, 6000
    AMD/ATI Radeon 2000, 3000, 4000, 5000, 6000, 7000 series
    AMD/ATI FirePro 3800, 4800, 5800, 7800, 8800, 9800, 3900, 4900, 5900, 7900
    Intel Intel HD Graphics, Intel HD Graphics P3000, Intel HD Graphics P4000
    Note: ATI X1000 series and nVidia 7000 series cards are no longer being tested and are not officially supported in CS6 – some basic GL functionality may be available for both these cards.
    Note: 3Dand some Open GL features are disabled on Windows XP, as stated on : http://labs.adobe.com/technologies/photoshopcs6/

    I've had several timeout since the pings were started. Got a some response times > 1ms (nothing greater than 7 or 8ms), but no timeouts.

  • What is difference between modify and update i am using

    hi
    what is difference between mofify and update
    my requiremen is to have three condition checkec while mofifying or updating from a internal table
    the three fields are
    cus no
    status
    date these all are primary key in the database table
    so which sould i use modify or update
    there might be entry already existing in database table or new entry to be created if already existin it should check on the primary keys and updatat if not it should add a record
    pls suggest whihc to use and how to implement the check on teh threee primary key
    like if modify ztable from table it_test
    now where condition ? can be used or not with modify? and if yes how
    if not should i use update will update create a new entry if no entry is there and please give syntex
    regards
    Arora

    Hi Nishant Arora,
    Modify: It works in performing two actions.
    They are: Insert + Update.
    For Example If a record that is exited in database, so you are modifying that record, it updates that particular record.
    Similarly, If the is not existed in the database, you are modifying it, it inserts a new record.
    Update: Update means just it updates the status, I mean it only updates the record. It doesn't inserts any new record if that particular record is not present in the database.
    These are the cases you need to write these statements.

  • What is Difference between SXMB_MONI and SXMB_MONITOR?

    what is Difference between SXMB_MONI and SXMB_MONITOR?
    Can any explain to this question.please?

    Hello,
    Both are same.
    SXMB_MONI is area menu which will contain all multiple transactions pertaining to monitoring.
    SXMB_MONI contains some functions viz monitoring for Bridging, Archived Msgs, Job overview, persistence layer analysis.
    SXI_monitor directly leads to the message monitoring for the IS, which is part of the SXMB_MONI.
    SXI_MONITOR directly executes the monitoring report.

  • What are the options "alert" and "passes" under my account info?

    Hi guys, I was going on viewing my account info, and I happened to see some options which I have no idea what are their usage? Can someone tell me what is the option "passes" and "alert" for? Thank you

    Passes will list any season passes you have purchased and still have some left to get.
    Alerts is to notify you of new music from artists you select.
    Go to the artist page in iTunes and scroll to the bottom and click on *Alert me*.

  • HT201303 was just having this problem until today. It is now all sorted and I can explain what to do very simply and easily.

    I was just having this problem until today. It is now all sorted and I can explain what to do very simply and easily.
    I remembered the answers to my questions, I just forgot "EXACTLY" how I entered the text - so I had to have them reset. The easiest way is to sign in through www.appleid.com. Then on the right click the "Manage your Account" link and sign in. Easy so far right. Then, as others have said, look on the left of the screen you will see a link called "Password and Security" - click on this. Now this is where the confusion begins. Some people have a link located directly under the existing questions that looks like this "Forgot your answers? Send reset security info email to blah blah blah email . If you see this click it and it will send an email to the "Rescue Email" address that you entered when you originally entered your answers. Follow the instructions contained in this email and you are done. If you cannot remember this email address or you have since closed it, you will need to go to the Itunes Express lane and send an email to Apple requesting them to reset your answers.
    HOWEVER IF YOU DO NOT SEE A THIS LINK UNDER THE QUESTIONS - this means that you DID NOT enter a Rescue email address when you originally set your questions. The only way you can now reset your Security Questions and Answers is to go to the Itunes Express lane and email Apple asking to have these reset. I have 2 apple accounts, one for myself and one for my daughter - as I did not include a rescue email I had to email apple. On both occasions, these questions were reset and an email sent to me exactly 24 hours after I sent them the request. I entered the new details, WROTE THEM DOWN EXACTLY AS I ENTERED THEM THIS TIME, entered a Rescue Email this time and I am good to go again. Simple. Now when I log in and click on "Password and Security" I do have the reset link visable. Apple support are good, they just take a bit of time to get things done, but they always seem to get there in the end. I just wish someone had taken the time to explain this somewhere else in the forum as it would have saved me much time and angst.
    To get to the Itunes Express Lane go to this website www.appleid.com make sure the correct country is displayed top right, if not change it. Once this is saved go to the tabs at the top of the screen and click Support. Then halfway down the next page you will see a photo of two random people with a title of Contact Apple Support - Click this. Scroll down until you see the itunes logo, to the right of this you will see the link Express Lane for iTunes Player and iTunes Store - click on this. One the right hand side of the next page click on the link "itunes Store". On the next page click the link "Account Management" check the radio button beside "itunes store account security", select your country from the drop down box and click "Continue". Under the heading MORE OPTIONS, you will see a clickable link called email - click this. Fill in your name, Apple ID and country. Then in the text box, write "I have forgotten the answers to my Security questions, would you kindly please reset them. Thank-You". Then Click Continue, you will be given a reference number and an email is sent to your address advising that generally someone will attend to your request within 24 hours. Like I said previously, I had to do this twice and both times it was reset however it was done within about 5 minutes of the 24 hour cut off, so you will have to be patient. I know 100% that this works for Australia - I am guessing other countries should be similar. Hope this helps someone somewhere!

    Standard troubleshooting...
    1. Try a Restart by pressing the sleep/lock button until you see the slider.  Slide to power off.  Restart by pressing the sleep/lock button until you see the Apple logo.
    2. Try a Reset by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider if it comes up. Takes about 5-15 secs of button holding and you won't lose any data or settings.
    3. Remove apps from Recently Used list...
    - From any Home Screen, double tap the home button to bring up the Recents List
    - Swipe up on the app preview card
    - Press the home button when done.
    4. If still a problem restore with your backup.
    5. If still a problem restore as new, i.e. without your backup. See how it runs with nothing synced to it.
    6. If still a problem, it's likely a hardware issue.

  • So I have a file on my desktop and I cannot open it, move it to a folder, or delete it from my mac. I dont know what it has in it, and that makes me suspicious. What can I do to remove this unremovable file from my computer? Is it a virus?

    First, I would recommend repairing the hard drive with Disk Utility.
    If that doesn't fix the problem, there's a very dangerous command you can execute in the Terminal.  This is very hazardous, because a simple typo can result in very drastic consequences.  I have seen people erase their entire hard drive by putting a space in the wrong place!  So, please follow the directions I'm going to give you very carefully!
    Open the Terminal, which is found in the Utilities folder in the Applications folder.  In the Terminal, enter the following:
    sudo rm -f
    Make sure to put a space after the "-f"!  Then, drag the troublesome file from the Finder and drop it on the Terminal window.  That should insert the path to the file in the command.  Then go back to the Terminal and press return.  You will be asked for your password, and when you type it, nothing will be shown as a security measure.  Press return again after entering your password.  The file should be deleted.

    Welcome to Apple Support Communities
    That's exactly what you need. A Mini DisplayPort to HDMI adapter and a HDMI cable. See > http://support.apple.com/kb/HT4241?viewlocale=en_US
    This is the only way to view a video on the TV. After connecting your MacBook Air to the TV, image on your TV should show immediately. Then, press Command and F1 keys to mirror your MacBook Air display, and open the video
