Technical Question regarding TCP Ports

Morning All
The Set up - 1xXP PC running BTNP and 1xWin7 Laptop running MSE
                   1xBTHHV2.0B
                   1xBTVision box (currently not connected)
I have posted elsewhere on here about strange results regarding attempts (via UDP ports) to connect to my PC and have been trying to stop this or even look into who, what and why. At this present time BTNP has been manually configured to report everything and I'm getting some interesting attempts. Anyway googling this, that and the other has sent me in the direction of TCP Ports.
Upon opening "netstat" via a command prompt on the PC it shows that 4 TCP Ports are currently "established" and 1 is showing "close_wait". All these refer to the localhost:**** which I guess is okay?
However, opening "netstat" on the Laptop shows 8 TCP Ports are currently "TIME_WAIT" (in the state section) and 1 refering to which IP the laptop is assigned with and the www IP address. It's the 8 I'm slightly concerned about. They refer to what I believe is the BT Vision server IP address (127.0.0.1). The same address is found on the BTV box.
Apparently, to block TCP connections the user needs to manually configure the router firewall which AFAIK can't be done on the BTHH2.0B.
So here's the Q's
1) Is it normal to have a computer TCP connection with what appears to be BT Vision?
2) If not how do I block/close the TCP ports without using a router firewall that appear to be BT Vision?
3) Why would the BTV IP address be dispalyed if the box has not been connected for some time?
None technical replies would be good

@ Roger.
Wow what a read!
Am I correct to assume that UDP transmissions are safe as they don't go anywhere as the firewall stops them? I'm still intrigued as to why various transmissions are attempted (ie. microconnect, BTVision, Binary Trojan maker etc etc etc).
Currently re reading yet again and will post regarding TCP...........
.............TCP has to make a connection? A packet is sent from A to B and back to A. It is then that data can be exchanged. A and B's serial numbers can also be exchanged. Then when they have a full 'duplex' connection, A and B can send data to the each other anytime they want. And all A has to do is just give the operating system some stuff to send?
That worries me or am I reading into this the wrong way?

    Greetings,
              I have a bit of a technical question regarding language alternative (Lang Alt), are these valid statements if there is no alternatives (using dc:title as an example):

  • Technical Question regarding ABAP

    Hi Friends,
    The question that i am shooting up , I beleive, might have come across in your projects also..
    Simple Scenario : I should generate a report about Invoices that are generated today.
    But the business is like that on any given day... there are about
    200,000 invoice documents generated.
    So my issue here are.
    1. Optimum way to declare an internal table: MUST be able to accomodate >200,000 records.
    2. Best way to fetch into internal tables.
    Awaitng your replies..

  • Very technical question regarding HDMI ARC

    Hi all, I'm planning out a HT purchase, and I plan on setting it up like this: Devices (Cable/PS4) -> TV (via HDMI)TV -> 2.1 ch Soundbar (via...) For the TV to Soundbar connection, I could just use an Optical connection, get 2.1ch lossless via Linear PCM and call it a day and be happy. But the HDMI ARC connection has me intreugied, and where my questions come in. 1.) Can I use HDMI ARC even if I NEVER have the TV's input set to the soundbar source (ie. making it a passive upstream audio only and essentially replacing the role of a Toslink Optical connection). 2.) If this even can be done, would I still get the benefit of Controlling the soundbar through my TV remote? (via Control through HDMI 3.) Lastly, would I still get the same S/PDIF, 2.1ch lossless audio LPCM this way? If it matters, the planned purchases are:TV: Sony X850CSoundbar: Sony HT-CT780  I've asked on some technical A/V forums before but no good response to this yet - maybe because my setup plan is an odd one, usually HDMI ARC is there to prevent the need for another cable (like Optical) but if I can get control from HDMI I think its worth investigating. Thanks! 

    I know it's a lot later but I wanted to give credit where credit is due. I wound up toying with the system myself and it works fine, and what Dimestore said is true.
    The ARC protocol is passive in the sense that it's constantly feeding back despite the input of the TV
    And honestly, the communication between the Sony devices is great. In fact, the TV itself can read the different inputs through to the soundbar and display them as separate inputs on the TV. It's pretty cool.
    Thank you both for your responses!

  • Technical question regarding Video Preview options in Seq Settings

    I am trying to wrap my head around some of the unique differences between FCP7 and PrP 5.5. What is the function of the Video Preview choices in the Sequence Setting menu? It seems standardized to I Frame Only MPEG with  other options depending on what your source footage is. Why would I use this setting as opposed to 1080 (for an AJA sequence made from Prores footage) or P2 (for an Adobe seq built from the same Prores footage) or Red which gives you no options then the one I just mentioned?
    In FCP when things were rendered they were used when I would export the sequence. Is PrP 5.5 the same? If I am previewing a 1080 sequence in I Frame Only MPEG, does that mean on output the whole entire sequence and effects need rendering? What is the best work flow when using Adobe or AJA sequences in regard to this Video Preview setting? It is so different from what I am used to I want to make informed choices.

    Maximum Bit Depth is only suitable when ingesting 4:2:2 material and exporting with AJA or BM
    Oh, man... not again. This is not true, at all. Maximum Bit Depth has nothing to do with 4:2:2 AJA or BlackMagic. And Maximum Bit Depth is not just for use with 10-bit or  greater source footage. It can be used with 8-bit material--DV, H.264,  MPEG2, anything--to great benefit.
    (The following is copied and pasted since I've written it so many times...)
    What Maximum Bit Depth  (either in the Sequence Settings or in the Export Settings) does is  enable Premiere Pro to render and composite in 32-bit floating point  color. It has nothing (or at least, little) to do with the source  footage, but controls how effects and transformations that shift pixels  around are rendered. Any effect in the Effects panel that has a 32-bit  badge on it will benefit from Maximum Bit Depth--the expense is greater  memory requirements and processing time, but the payoff is a higher  degree of color fidelity and precision in the rendered image. Gaussian  Blur, for example, is a 32-bit effect that will show a great difference  between when it is rendered with MBD on versus when it is off--even if  you're rendering/exporting to an 8-bit format, like DV.
    From Karl Soule's article on this topic, The Video Road – Understanding Color Processing: 8-bit, 10-bit, 32-bit, and more:
    A DV file with a blur and a color corrector exported to DV without the max bit depth flag. We  will import the 8-bit DV file, apply the blur to get an 8-bit frame,  apply the color corrector to the 8-bit frame to get another 8-bit frame,  then write DV at 8-bit.
    A DV file with a blur and a color corrector exported to DV with the max bit depth flag. We  will import the 8-bit DV file, apply the blur to get an 32-bit frame,  apply the color corrector to the 32-bit frame to get another 32-bit  frame, then write DV at 8-bit. The color corrector working on the 32-bit  blurred frame will be higher quality then the previous example.
    A DV file with a blur and a color corrector exported to DPX with the max bit depth flag. We  will import the 8-bit DV file, apply the blur to get an 32-bit frame,  apply the color corrector to the 32-bit frame to get another 32-bit  frame, then write DPX at 10-bit. This will be still higher quality  because the final output format supports greater precision.
    A DPX file with a blur and a color corrector exported to DPX without the max bit depth flag. We will clamp 10-bit DPX file to 8-bits, apply the blur to get an 8-bit  frame, apply the color corrector to the 8-bit frame to get another  8-bit frame, then write 10-bit DPX from 8-bit data.
    A DPX file with a blur and a color corrector exported to DPX with the max bit depth flag. We will import the 10-bit DPX file, apply the blur to get an 32-bit  frame, apply the color corrector to the 32-bit frame to get another  32-bit frame, then write DPX at 10-bit. This will retain full precision through the whole pipeline.
    A title with a gradient and a blur on a 8-bit monitor. This will display in 8-bit, may show banding.
    A title with a gradient and a blur on a 10-bit monitor (with hardware acceleration enabled.) This will render the blur in  32-bit, then display at 10-bit. The gradient should be smooth.
    What Maximum Bit Depth does is allow  Premiere Pro's rendering engine to have more room to run, with a higher  degree of precision. It's important to remember that rendering  internally is different than exporting--and even when you're "rendering"  previews, you're actually exporting, because you're creating composited  video files of one sort or another. That's why there is a Maximum Bit  Depth checkbox in the Sequence Settings--that affects preview files, not  exports. When you're using hardware MPE, you're always operating in  MBD--or more specifically, you're rendering in 32-bit linear color.  Generally, this is "better," though I've lamented about the negative  effects of linear color processing, e.g. annoying opacity differences on  dissolves, shaggy alpha channels, etc.
    The bottom line is  that Maximum Bit Depth allows Premiere Pro to generate better  (subjective), more technically accurate (objective) output, regardless  of the input and output format.

  • Technical question regarding network settings

    There does not seem to be much "answered questions" on this forum -- more like a gripe  forum - but I'll give it a shot:
    I occassionally do file transfers between my mac and pc, using a connected ethernet cable -- and have had no problems with this until after I did a successful transfer today.  Then I was not able to do another.  I looked at my Local Area Connection settings - Details - and noticed that the Autoconfiguration IPv4 address that was once there, was no longer there.  This may explain why the mac was not able to 'find' the pc -- but I'm not sure.  Looking at other sites on the web, it appears there should not only be a Autoconfiguration IPv4 address (which was there before, because I took the IP address 169.254.xxx.xx address from there before) - but there also should be an Autoconfiguration IPv4 'enabled' [yes] setting there also, which also does not appear in my settings.  I suspect I must have inadvertantly changed a setting when I did the last transfer, but do not know what or how to correct it.  Thank you!

    Some questions if you do not mind:
    #1 What kind of cable is it?
    #2 Is this cable connected directly to the two computers or do you have a cable for those two computers connected to something else?
    #3 If you have a cable for those two computers connected to something else, what is the band and model of that something else? For example I have my computers connected to a Linksys E4200v1
    #4 Regardless if this cable connected directly to the two computers or do you have a cable for those two computers connected to something else, do you know how to setup a Static IP on your computer?

    I have a Macbook from December 2009

    Hi thanks for answering.
    how would you make the gateway and the certificate comply with this.
    my gateway certificate is connectgw.companyname.com IP xxx.xxx.xxx.xxx
    my web server certificate is connect.companyname.com IP xxx.xxx.xxx.xxx
    the ConnectionBroker only allows one Gateway?

  • Technical question regarding ptcor code

    Hello,
    I have the following problem with my custom PTCOR application: (WTimeCor is the actual application name)
    When I submit all time events, do a EXECUTE_DELEGATE in PTCOR_UIA_FORM_DELEGATE and then execute the method restartService(); of VCConfirmation, everything works fine but the overview falls back to the current week.
    When I try saving anything afterwards (deleting, modifying, creating) without using restartService() before, I get the following BAPI Error:
    No customizing for status type COR, status POSTED, transition event SEND
    any property I need to reset? like FORM_DIRTY or setting a different request-id?
    thank you very much

    thanks for you answer. I sense it may be some kind of unfinished workflow.
    I tried to skip review steps inside the application and save the modification all at once, which means:
    PTCOR_UIA_FORM_PREPARE with IM_COMMAND "CREATE"
    FORM_ACCEPT with IM_COMMAND "ACCEPT_SEND" (copy request-id and structure content from FORM_PREPARE output)
    FORM_DELEGATE with IM_COMMAND "NEXT"
    and
    FORM_DELEGATE with IM_COMMAND "EXECUTE_DELEGATE"
    all triggered from WD Java. I took these FM from the original PTCOR application, I don't know if there's a FM that saves a time event without any workflow steps.
    Now what restartService() does is, it navigates via the FPM back to the application so the application is created anew, PTCOR customizing is being read and WEEKLY_CALENDAR is read as well (if I understood that correctly). It seems to initialize a new workflow so I am able to save a new time event to via the above method.
    Best Regards

  • A technical question regarding NOKIA 301 Dual SIM

    Several days ago I bought  new NOKIA 301 Dual SIM.
    It is equipped with charger NOKIA AC-20E, input AC 100 - 240 V/120 mA, output  DC 5V/750 mA.
    Also, I have several other (old or non-Nokia) chargers:
    1) NOKIA  AC-10E, input AC 100 - 240 V/160 mA, output DC 5V/1200 mA;
    2) NOKIA  AC-3E, input AC 100 - 240 V/60 mA, output DC 5V/350 mA (for this charger, I have proper adaptor for  NOKIA 301 Dual SIM);
    3) USB charger L-STAR , input AC 100 - 240 V, output DC 5V/1000 mA+/-5%
    May I use these above listed (old or non-Nokia) chargers for charging my new NOKIA 301 Dual SIM (or which of them are compatible with NOKIA 301 Dual SIM)? Thank you.
    Solved!
    Go to Solution.

    Choose the one with output 5V, 1200mA or the one which came for your phone, output 5V, 750mA.
    More the output mA, the faster battery will charge. I don't recommend non Nokia ones.
    Hope this helps.

  • Another technical question regarding NOKIA 301 Dua...

    Sunday I was in the mountain where the network coverage was very sparse or missing. Of course, my phone lost the operator signal. But when I arrived again in the town (where the operators signal is normal), the phone could not manage to find the operator signal (SIM 1) again. After restarting the phone by switching off and on, the phone registered both operators signals (SIM 1 and SIM 2 ) normally. Do you think that this situation is normal? For example, my old phones (1680, 1650 and 6303) always manage to find the operator signal when, after disappearance, the network coverage appeared again, without need to restart them. Thank you.
    Solved!
    Go to Solution.

    Well.. I'd say its normal and maybe its a better thing to do. When under no network coverage for a prolonged period, my Nokia 311 does not register to network even when I'm finally in the network coverage area.
    The point is that the phone gives up and stops trying hard to find the network coverage when it is not able to receive any network for a prolonged period. This is actually good as the phone will firstly stop wasting its battery just to keep the antennas highly sensitive and look for network.
    That said, i think it still keeps trying to find the coverage, but the attempts are done not in immediate succession. I'm able to say this as sometimes my phone catches up the network again by the time I really reach home after entering the coverage area.
    Whatever it is, I'm sure a restart won't hurt much especially if it helps in saving battery and also to save you from the high radiations the antennae emits while looking for the network in no coverage areas.

  • Question regarding mic plugged into audio in/optical digital audio in port

    So I have this external headset... headphone/mic set combo... I plug the headphone jack in the headphone slot and the mic jack in the audio in/optical digital audio in port slot in the back of my IMAC. I go to my system preferences select "sound" and "line in - Audio line in port". But when recording, it's still recording from the internal mic? How do I just record just from the external mic??? What am I doing wrong? I've read all the other questions regarding how to get the external mics to work, but it's still recording from the internal mic? Help?
      Mac OS X (10.4.9)  

    I never expected APPLE wouldn't make a mac that didn't have a proper mic jack?
    It has a proper one, a good one, a professional one, not the toy that comes with most PCs. Apple has used line level analog audio input for years.
    From Wikipedia;Line level is a term used to denote the strength of an audio signal used to transmit analog sound information between audio components such as CD and DVD players, TVs, audio amplifiers, and mixing consoles.
    In contrast to line level, there are weaker audio signals, such as those from microphones and instrument pickups, and stronger signals, such as those used to drive headphones and loudspeakers. The strength of the various signals does not necessarily correlate with the output voltage of a device; it also depends on the source's output impedance, or the amount of current available to drive different loads.

    The client request it's going trough an ASA, in the ASA side I see that the TCP connection it' half-open with SAaB flags. It seems that the VIP never replies with SYN+ACK to the ASA...
    Thank you.
    Best regards

    Hi Norberto,
    The log messages you are getting are most probably the probe connections and not a failure, looking to them you will see your ACE is establishing TCP connection on 4444 then it will teardown the connection with FIN which is expected since you are using TCP keepalives.
    I would recommend to go back and define the problem exactly, what are you exteriancing when you try to telnet on port 4444 toward the VIP from the client?
    Run sniffing software on the client, the server and enable capture on ACE and ASA will give you exact idea what you are experiencing.
    Note: The ASA and the ACE has great capture feature which will show you exactly the packet flows.
    Note: Since you are applying NAT on the client requests, you should see the NATed IP address on the server capture.
    Note: With L4 load balancing the ACE is not spoofing the clients' request, it just forward the SYN, SYN+ACK and ACK between the server and the client.
    Let me know if you have any other questions.
    Best regards,
    Ahmad

  • Can a real Server be applied in two different server farms associated with two different VIP IP and TCP Port

    Good day everyone,
    I have a question in regard to real server operation with different server farms, and VIPs
    Can a Real Server be associated ( for simpliciy) with two different Server Farms that have a VIP associated with each, servicing the same TCP Port (443).
    Example:
    SF-A
    RSRV-1: 192.168.1.10 /24
    RSRV-2: 192.168.1.11 /24
    VIP-A: 192.168.1.20 /24
    VIP-A: https:web-A
    Protocol: HTTPS
    SF-B
    RSRV-2: 192.168.1.11 /24
    RSRV-3: 192.168.1.12 /24
    VIP-B: 192.168.1.30 /24
    VIP-b: https:web-B
    Protocol: HTTPS
    Client-A: 172.16.128.10
    Client-B: 172.16.128.15
    I have attached an sketch depicting the connectivity.
    As always any feedback/Suggestions will be greatly apprecaited.
    Cheers,
    Raman Azizian

    Raman,
    This type of config is no problem. What the server is doing is virtual web hosting. The server would have two different web services running for the same IP, but each listening for a unique host header.
    From an IP point of view both connections would be destined to the rserver address on port 80, but in the http header they would have two different Host headers.
    one for www.example1.com and the second for www.example2.com. If the web server is configured correct so each host name is tied to one web service it will not have any issues.
    The config you attached looks ok. The way you have the sticky group is ok doing source IP. If you use cookies for the sticky group I would suggest you create two sticky groups each with a different cookie name and add the same serverfarm to both groups. The client will only send a cookie for the domain it received it from so using the same cookie in two vips could cause problems if the same client hits both vips.
    Hope that helps
    Regards
    Jim

  • Single Web Dispatcher listening different TCP port

    Dear experts,
    I would like to post a question regarding Web dispatcher.
    Our present environment has a Web dispatcher binding to single domain which is VeriSign Certified. We have received a requirement to support another CA for SSL authentication at Web Dispatcher since VeriSign is not their trusted partner. Hence, i am exploring the below possibilities.
    1. Configure another port for SSL with same WD instance. Is this possible?
    2. In case point 1 not possible, i will setup another WB instance to listen on differnt TCP port. In this case, is it possible to have two WD binding to single Message Server? The XI version is 7.0.
    Appreciate your views and advices.
    Thanks in advance.
    Regards,
    Ravi

  • How to do a silent configuration of SQL Server 2005 to a static tcp port ?

    Hello,
    I have a SQL server 2005 but after checking the ports of sql server,it is observed that dynamic ports are being used.
    I want to install SQL server 2005 and configure SQL serevr to a static TCP port by using silent mode of installation.There are ways to do it using SQL configuration manager and using server network utility but I want it through the silent mode.
    Please help to assist how this can be achieved through silent mode of installation.

    Hi AshishB,
    According to your description, you want to configure SQL Server to a static TCP port by using silent mode of installation. I recommend you use WMI scripting and the SQL Server WMI provider. After installation, change the TCP/IP port with the script. For
    more information about silent installing with fixed TCP port, you can review the following article.
    http://social.msdn.microsoft.com/Forums/sqlserver/en-US/914f8b72-3164-47ae-91fb-f7ed6f8ea7e6/silent-install-with-fixed-tcp-port?forum=sqlexpress
    There is detail about how to configure that manual by launching the SQL Server configuration manager, enabling TCP/IP connections, specifying the ports from the command line, you can review the following post.
