UDP ip address

I have two ethernet PCI cards in my PC.  One of them is gigabit (Intel PRO/1000 GT) and the other one is 10 BASET.  I found a couple of functions, i.e., UDP Write and UDP Read in my Labview 6.0 which may work for my purposes.  I was able to set a unique IP address for each of the PCI cards.  Each of these cards will be used to communicate with a unique remote device (therefore a unique IP address).  I see that in UDP Write and UDP Read, there is a way to specify the IP address of the remote device.  I don't see how I can associate the IP of my PCI cards with the UDP Write and Read functions.  I have fixed the routing table.  Now the missing part is "how may I send a UDP message out via a particular PCI card or receive a UDP message via a particular PCI card.  Thanks for your help.   

You can specify the network address to listen for UDP datagrams on when you use UDP Open (LabVIEW 8.20 and later). This would require opening a reference for each network card. There was no way to do this before 8.20.
I believe LabVIEW will perform the UDP Write using the network card specified when opening the connection reference, but I am not positive. Maybe someone from NI can confirm this?
Now is the right time to use %^<%Y-%m-%dT%H:%M:%S%3uZ>T

  • UDP Destination Address

    Hi,
    I’m currently using UDP read VI provided by NI to retrieve UDP broadcast messages.  Parsing the data out, it appears the VI only returns the data segment of the datagram and strips away the header information.  So I am not able to retrieve the destination address (i.e. broadcast address), but only the source address in which it was originated.  Is there a way that I could retrieve this information?
    Thanks,
    Nina
    Solved!

    I still don't quite see the purpose. Do you want to determine if it was a broadcast versus an unicast?
    Broadcasts typically don't cross subnet boundaries. In the old days routers often forwarded directed broadcasts, but this is now normally blocked to e.g. prevent smurf attacks and others. (except for special cases such as dhcp etc.)
    Also don't forget spoofed packets. If a local machine would place a packet on the wire with a random destination IP, but with your MAC address in the Ethernet header (or the Ethernet broadcast address FF:FF:FF....FF), you'll still get it.

  • How I Got iChat to Work

    I finally got my iChat to work after a lot of research, especially from reading this forum. I want to thank Ralph John (Great website), Tony defcom1 (netgear suggestions), and RJ in WI (for testing my iChat connection). I want to share with the readers of this forum what I did so that it might help you. I basically had to implement practically every suggestion I found.
    My equipment: mac mini with core duo and 1 GB of ram, OSX 10.4.7 connected wirelessly to a Netgear WRG614v6 router which is connected to a SBV5120 Motorola VOIP cable modem. My broadband speeds are 12Mbps download and 1.7 Mbps upload. I'm using iChat with AIM.
    Quicktime preferences, streaming: changed speed to 1.5Mbps
    iChat preferences, accounts, server settings: changed port from 5190 to 443. Note that you have to be logged out of AIM to change this. I did this before I learned about port forwarding so I could log into AIM.
    System preferences, sharing, firewall: off. It also works with firewall on but with the correct ports opened. Click on New...select other, TCP port numbers: 5190, UDP port numbers: 5190, 5060, 5678, 16384-16403, and description: iChat. For the UDP ports, there needs to be a space after each comma.
    Set up static IP addresses:
    Step 1: Gather the information you'll need. You have to access your router directly via Safari by entering in the router's IP address, name and password. For the WGR614v6 it is http://192.168.1.1, name: admin, password: admin. Note: you can't change the name. The default password is admin, but you should change it.
    Click Router status in the menu on the left side and write down the Domain Name server IP addresses. There are two.
    Step 2: Back in my mac: System preferences, network: click Configure, click TCP/IP. For Configure IPv4, select Manually. IP Address: 192.168.1.22, Subnet mask: 255.255.255.0, Router: 192.168.1.1, DNS servers: The two you got in Step 1.
    Note: I used 192.168.1.22 for my mac mini, 23 and 24 for two other PCs on the network and 100 for my network printer. Other numbers will also work.
    Step 3: Back in the Netgear router settings: Click on LAN IP Settings: Uncheck Use Router as DHCP server.
    At this point, check to see that you still have internet access. Otherwise, recheck your settings. If all else fails, press the reset button on your router to return to the factory settings.
    Set up Port forwarding: Back in the Netgear Router settings: Click on Port Forwarding/Port Triggering.
    1. Click on Add Custom Service. Service Name: iChat1, Service type: TCP/UDP, Starting port: 5190, Ending port: 5190, Server IP Address: 192.168.1.22. Note this is the same as the IP Address for your mac with iChat. Click Apply.
    2. Click on Add Custom Service: Service Name: iChat2, Service type: UDP, Starting Address: 5060, Ending Address: 5060, IP Address: 192.168.1.22. Click Apply.
    3. Click on Add Custom Service: Service Name: iChat3, Service type: UDP, Starting Address: 5678, Ending Address: 5678, IP Address: 192.168.1.22. Click Apply.
    4. Click on Add Custom Service: Service Name: iChat4, Service type: UDP, Starting Address: 16384, Ending Address: 16403, IP Address: 192.168.1.22. Click Apply.
    Adjust UPnP settings: In Netgear router settings: click on UPnP. Leave UPnP on. Change Advertisement period to 5 and Advertisement time to live to 2. Note: UPnP by itself did not work for me.
    Logout off you router.
    Start iChat. Make sure you can connect to the Apple testers, AIM appleu3test01, appleu3test02, appleu3test03.
    Hope this works for you. I used to get -8 errors most every time. Now I am error free.

    Hi Eric,
    Welcome to the Apple Discussion Pages.
    It does seem that iChat regards the fact that a PC with no Mic and no camera is not sending any data and regards this as a fault and ends the chats, normally, with the 10 sec error.
    Glad you found a solution.

  • Socket communication very slow on Mac OS X 10.6

    Hi everybody,
    I'm using a socket based communication in an application and in Mac OS 10.5 everything works quick and flawless using XCode 3.1.4.
    In Mac OS 10. 6, using XCode 3.2.4, I set the Mac OS X 10.6 SDK, I recompiled the app. but the responsiveness of the app is terrible slow. The GUI itself runs OK but any socket related action is painfully slow (sometimes connection timeout).
    The socket communication is implemented using standard CFSocket classes.
    Is this a XCode migration issue from 3.1 to 3.2 or a Mac OS 10.6 related one (I've seen lots of complains on networking issues)?
    Thank you very much,
    Dan

    Thank you very much for the info but why it worked (and really fast) on 10.5. I also wonder why I didn't run into TCP_NODELAY problem there ? My TCP buffer size is 1K and I'm using the same testing environment.
    Of course there is much more to it than some init parameters but still, what could be so different on 10.6 ? And I tried already the sysctl.conf TCP_NODELAY setting but no effect.
    This is the code (briefly):
    1. CONNECT
    // Create signature from ip and port
    struct sockaddr_in sin; /* TCP/UDP socket address structure. */
    self->m_RemoteSocketSignature = (CFSocketSignature*)malloc(sizeof(CFSocketSignature));
    self->m_RemoteSocketSignature->protocolFamily = PF_INET; /* IPv4 */
    self->m_RemoteSocketSignature->socketType = SOCK_STREAM; /* Stream oriented. */
    self->m_RemoteSocketSignature->protocol = IPPROTO_TCP; /* TCP */
    memset( &sin, 0, sizeof( sin ) );
    sin.sin_len= sizeof( sin );
    sin.sin_family = AF_INET; /* Address is IPv4. Use PF_xxx for protocol
    description, AF_xxx for address description. */
    /* sin.port and sin.addr are in network( big endian ) byte order. */
    sin.sin_port = CFSwapInt16HostToBig( port );
    inet_aton( [address UTF8String], &sin.sin_addr ); /* inet_aton() gives back
    network order addresses from strings. */
    self->m_RemoteSocketSignature->address = CFDataCreate( NULL, (UInt8 *)&sin, sizeof( sin ) );
    // Connect the Write & the Read streams to the socket
    CFStreamCreatePairWithPeerSocketSignature (
    kCFAllocatorDefault,
    m_RemoteSocketSignature,
    & m_ReadStream,
    & m_WriteStream
    if((m_ReadStream != NULL) && (m_WriteStream != NULL))
    bOpenWrite = CFWriteStreamOpen (m_WriteStream);
    bOpenRead = CFReadStreamOpen (m_ReadStream);
    2. RECEIVE
    CFIndex iTotalBytesRead = 0;
    while (true == CFReadStreamHasBytesAvailable(m_ReadStream))
    char buffer[1024];
    CFIndex bufferLength = 1024;
    CFIndex iBytesRead = CFReadStreamRead (
    m_ReadStream,
    buffer,
    bufferLength
    // Error ?
    if(iBytesRead < 0)
    return iBytesRead;
    // EOS ?
    if(iBytesRead == 0)
    return iTotalBytesRead;
    iTotalBytesRead += iBytesRead;
    if(string != nil)
    [string appendString:[NSString stringWithCString:buffer length:(unsigned)iBytesRead]];
    3. SEND

  • How to set the ports on wrt150n for my xbox360

    help me!!!!!!!  I need evry step

    I just contacted Linksys/Cisco about this problem of the WRT150N not connecting properly with the Xbox 360 Live.
    The support person online said this model does suport it.
    I do not know if this person was right or not but here was the advice they gave online:
    1. Assign static IP, subnet mask, gateway and DNS on the Xbox 360.
    a) Go to the System area of the Xbox Dashboard.
    b) Select Network Settings.
    c) Select Edit Settings to adjust your:
    IP Settings (IP Address = 192.168.1.20, Subnet Mask = 255.255.255.0, Default Gateway = 192.168.1.1)
    DNS Settings (Primary = 4.2.2.1, Secondary = 4.2.2.2)
    2. Port forwarding
    88 (udp)
    3074 (tcp & udp)
    a) Access the router's web-based setup page and click on Applications and Gaming tab.
    b) Under Port Range Forwarding sub tab, we will enter two entries for us to forward the two ports.
    First Entry
    Name = Xbox360a
    Start = 88
    End = 88
    Protocol = UDP
    IP Address = 192.168.1.20
    Enabled = Checked
    Second Entry
    Name = Xbox360b
    Start = 3074
    End = 3074
    Protocol = Both
    IP Address = 192.168.1.20
    Enabled = Checked
    c) Save the settings.
    3. Still on the router's web-based setup page, click on Setup tab.
    a) Set MTU from Auto to Manual.
    b) Change the MTU size from 1500 (default) to 1365.
    c) Scroll down and save the settings.
    4. Power cycle. Unplug the power adapter of the router for 10 seconds and plug it back again.
    5. On your Xbox 360:
    a) Go back to the System area of the Xbox Dashboard.
    b) Select Network Settings.
    c) Select Test Xbox Live Connection.
    d) After the system has completed its tests, select More Info to learn more about your network, paying close attention to any test that failed.
    I checked more with Linksys and here is a Web page related to this, but note that this is for Xbox and not Xbox360. What is interesting to note is this from the PDF: " Before proceeding, please take note that Linksys does NOT support the configuration of Xbox™. The following instructions simply tell you how to configure the router for the Xbox™, not the game console itself. For technical support on the Xbox™, contact Microsoft."
    I think this may support my case that Linksys and Xbox are not good friends.

    P.S. - It is my guess that Linksys/Cisco is wrong here; that they have not recognized the problem or are not willing at this time time to acknowledge it. What do you think?

  • Need help adding ports to my router.

    I have a Linksys WRT54GS Router. I am having an issue with Xbox Live and I was told by Xbox customer support to add the ports UDP 88, UDP 3674, and TCP 3074. The problem is is that I have no idea how to do this. I am at the Applications & Gaming tab of the Router page (192.168.1.1), I just don't know where to put the numbers. Any help is greatly appreciated.

    First, setup up a static IP address on the XBOX. I can't tell you how to do that. Check the manual. Currently the XBOX is probably on "automatic IP address" or "DHCP" or whatever they have called it. Set up a static IP address and use these numbers on the XBOX:
    IP Address 192.168.1.50
    Subnet Mask 255.255.255.0
    Default Gateway 192.168.1.1
    DNS 192.168.1.1
    If the XBOX has some Status pages to check the current IP address verify that you have those values after the change. Also verify you have a working internet connection on the XBOX.
    Now the port forwarding. I assume it looks something like this demo UI. For port UDP 88 enter
    Application udp88
    Start 88
    End 88
    Protocol UDP
    IP address 192.168.1.50
    Enable SET
    Do similar with all other ports. The application name is only a descriptive text for you. You can enter anything you like, but keep it short and simple and don't use special characters in the name. The above "udp88" is O.K.
    Don't forget to save the settings at the end.

  • Updated instructions for connecting to Xbox Live

    Hi everyone,
    Like many others, I can't seem to get my Xbox Live to connect consistently through the Airport Extreme. There is a ton of lag. I have been working on this for about a week and there have been some great posts related to this issue. However, all of the instructions and Youtube videos I have found aren't using the current OS, so I just can't seem to make it work.
    Can someone write out the detailed instructions for connecting to Xbox Live using Airport Utility 6.1? Or, if there is a post somewhere, I would appreciate it if someone can point me to it.
    Thanks!
    Patrick

    Hi there,
    You might need to forward/open ports on your router first so that your xbox's connection will work very well.
    In this link, Click Here, you can see an example on how to forward ports.
    But in your case, forward/open ports for your xbox's connection.
    Under the Port Range Forwarding page, enter the following:
    > Application=xbox1 Start Port=2869   End Port=2869   Protocol=TCP      IP Address=(IP of the xbox)  Enabled = Checked
    > Application=xbox2 Start Port=10280   End Port=10284   Protocol=UDP      IP Address=(IP of the xbox)  Enabled = Checked
    > Application=xbox3 Start Port=1900   End Port=1900   Protocol=UDP      IP Address=(IP of the xbox)  Enabled = Checked
    > Application=xbox4 Start Port=10243   End Port=10243   Protocol=UDP      IP Address=(IP of the xbox)  Enabled = Checked
     > Application=xbox5 Start Port=88   End Port=88   Protocol=Both
          IP Address=(IP of the xbox)  Enabled = Checked
    > Application=xbox6 Start Port=3074   End Port=3074   Protocol=Both
          IP Address=(IP of the xbox)  Enabled = Checked
    Good luck!

  • Problem in SNMP4J Installation

    Hello everyone,
    I'm working on developing an SNMPv3 based NMS software for a Licensed Band cellular Radio Backhaul, using SNMP4J. My major concern in this project is to do both, manager as well as the agent part.
    Being a beginner, I'm facing problem with the installation of the software itself.
    I downloaded snmp4j-agentx-1.3.1a , currently working on Windows XP platform and trying to execute them over the simple command prompt of Windows (Will be working over Eclipse IDE later).
    Since there was no online help available regarding the installation steps of this software, i tried n number of open forums which gave me the idea that certain .jar files were to be executed. However, no matter what i tried, all I got were Class Manifest errors. or, NoClassDef errors. This led to more confusion, resulting in multiple copies of the extracted snmp4j-agentx-1.3.1a folder at various locations. Also, is there a particular sequence in which these files are to be compiled/executed.
    I also made a simple test code that should make a PDU and send it successfully. Since i can't execute and check it, i 'm a bit doubtful about it too.
    // checking for a simple request pdu and sending it.

    Hi,
      Client copy is important when your adding Java Addin. The java stack will be on this client only.
    Can I perform client copy after J2EE installation?
    Yes you can.. create client just say 555 give this client in while adding java addin. It will create another instance. It might not be a problem. If possible, try to delete the java instance refer to the installation gude.
    If not, do I need to uninstall and start the installation from the scratch?
    In my view not required from scratch
    Also Please let me know the procedure for client copy?
    Go to Tcode scc4 to create client give the required details if possible all.
    Remember the client you created in the above transaction.
    Try to login system using the created client number and userid is SAP*
    and passwrd is "PASS".
    Go to tcode sccl there you have copy the data from which client. Try to give the profile which is mentioned in the installation guide..

  • Port for uTorrent - WRT54GC

    Hi,
    I need one  more help.
    I want to release ports for uTorrent.
    I have a WRT54GC router.
    I successfully logged in, and clicked on Applications and gaming, and I think there I should typed ports in the tab Port range forwarding.
    Since I'm not good at that stuff, and it's my first time doing it. I want to know what numbers are for Start and End port for uTorrent, or where can I find it. I have uTorrent 2.0.3 and I only found the current port (for incoming connections) in Setup guide. In Preferences and elsewhere I didn't find anything with 'port' in it.
    As for the Protocol I would go both (TCP and UDP), IP address is the same, and will check Enabled. I only don't know the Start and End port.
    Thanks in further and I appreciate the help! 
    Thanks,
    Aleks
    Solved!

    Or should go on the tab Port range triggering. If so, what are the numbers of Triggered range and Forwarded range?

  • Reject sip/h323 calls by IP?

    i have a few sip/h323 providers. I have also enabled sip/h323 on my as5400xm(this is for my asterisk server). Since i'm using these providers, i have to put their IP in my access-list. my concern is, since my gateway is accepting sip/h323 calls. what if these provider send the calls to my gateway? so i was thinking of a way to restrict this. It could be as simple as tweaking the access-list. but I don't know. Please help.
    here's how i have my access-list setup:
    access-list 101 permit tcp host 10.10.10.10 any
    access-list 101 permit udp host 10.10.10.10 any

    Thanks in advance

    Ah, so you just want to restrict VoIP calls from L3 addresses other than your provider?
    That's just a simple ACL to open up traffic to your SIP ITSP's IP external addresses, and block anything else.
    You can get what IPs and ports are used by your provider, but here is what you need open on the Cisco side inbound for an inbound ACL on a WAN interface:
    UDP - ITSP address:ITSP SIP Port to External interface:5060 - For SIP signaling
    ITSP address:ITSP RTP Port Range - External interface:16384-32767 - RTP traffic
    ITSP's port range could be anything between 1024-65535.  SIP usually comes from UDP/5060 from the ITSP, but doesn't have to.  Verify with them, or look at a SIP debug or packet capture to verify.
    The implicit deny will take care of everything else.

  • Minidlna Server Stops Responding

    minidlna starts up and will serve media OK. However, after a period of time it stops responding - clients can't see the server. Restarting it fixes the problem for a while, until it stops responding again. I have logging turned up to max, but no errors are shown apart from the ones shown below when it first starts up.
    [2013/07/02 10:20:42] minidlna.c:885: warn: Starting MiniDLNA version 1.0.25 [SQLite 3.7.16.2].

    [2013/07/02 10:20:42] minidlna.c:991: warn: HTTP listening on port 8200

    I had the same issue when I was using a semi-managed network switch, which could understand multicast traffic. It tracked the IP_ADD_MEMBERSHIP and IP_DROP_MEMBERSHIP requests, so that multicast traffic would only be sent to those ports, that have joined the multicast group before. The problem was, that there was some kind of timeout after which the switch forgot about the joins, so that the multicast packets weren't sent to any port, because there was seemingly no one listening.
    I replaced it with an unmanaged switch that handles multicast packets like broadcast, sends them to all ports and have the clients throw them away, if they are not interested

  • "Port overlap occured" error with WRT54G2 v1 firmware 1.0.03

    I'm trying to port forward the below ports. Problem is that it says "port overlap occured, please change your entry". I've tried with UPnP enabled/disabled and static ip address. No difference.
    Can anyone help me?
    Thanks.

    Solved!

    Hello deepz9, the reason why you're getting "port overlap occurred,..." because the ports was not entered properly. By the way, what type of device are you using? Is that a gaming console or a PC? If you open ports you need to assign static ip to your device in order to avoid connection problems because if the device is on DHCP then it'll get a different IP the next time you turn it on. Try to follow this steps on how to forward the ports into your router.

  • Solution for Apple TV 2, Xfinity router, Ethernet connection and Home Sharing

    I have read over the past week the problems people have been having configuring their Apple TV and Home Sharing. I was experiencing the same issues as others....until tonight. I finally got it to work with an Ethernet connection. Previously, I was only able to get it to work via wifi and home sharing would drop after awhile.
    1) Xfinity router settings. Like others I was suspicious if the Xfinity router was causing the issues because of the separation between wifi network and Ethernet network. It's not the router problem. I disabled the firewall. Enabled port forwarding. Gave a static IP address to the Apple TV. Added forwarding of ports
       123 TCP
        3689 UDP (all other support says this should be TCP but searched through and found a thread that suggested changing to UDP...this was the key)
        5353 UDP
        80 TCP
        443 TCP
        53 TCP
    DMZ is off
    Device discovery is disabled
    Port triggering is disabled.
    The wifi is setup and functional using DHCP. Lease time is 1 week.
    RESET ROUTER AFTER ENTERING CONFIGURATION.
    2) Mac computer. As of this posting the latest version of iTunes installed. Latest Safari version. All programs updated. Turned on Home Sharing. Turned off firewall. Gave Mac a static IP address. Set Mac for hard drive to never sleep. Set monitor to sleep after 15 minutes. Set date and time to automatically find based upon time zone. ( Apple TV needs to be set to the same time zone as computer and set to manual). Enabled file sharing amongst users on Mac.
    3) Apple TV. Ethernet connection. Configured TCP/IP to static IP address  I configured on router for the Apple TV. Turned on AirPlay. Set date and time to manual and set as the same time zone as the computer with iTunes. Turned on Home Sharing. Using latest version of Apple TV.
    Once the router was reset ( not restored and not just resetting the wifi. A complete router reset), the Apple TV found my iTunes library. It's been running now for over an hour and no drop in the home sharing. Working beautifully. I will be testing in the next couple days allowing the Apple TV to sleep, turning the firewall on the router to a minimal setting to see if it changes anything.
    Just tested the AirPlay from my iPad 2 to the Apple TV while the Apple TV is connected via ethernet connection and it works. At this point it appears that the setup is correct and complete with no errors.
    As a side note, the Ethernet connection between my router and Mac is via commercial devices using the power outlets as the wiring.
    Hope this helps many of you that were/ are struggling to get this to work like I was.

    spma3,
    Appreciate your further message. As you say "it's not fixed", but at least your solution appears to be a viable workaround!
    My Cisco RVS4000 Router will permit me to forward ports for up to 15 applications. Of these, thirteen already have default entries added, although none of these are presently Enabled. For example, here's just 2 lines...
    Application           HTTP        NTP
    External Port          80           123
    Internal Port           80            123
    Protocol                TCP          UDP
    IP Address            No entries at both
    and the Enabled box for both is unchecked. In fact none of these 13 possibilities is Enabled.
    To do what you are advising, I would need to...
    1) Enable the above Port 123 entry, changing it from UDP-->TCP.
    2) Add new entries for 3689 UDP & 5353 UDP... using the two free slots at the end of the table.
    3) Select three of the default entries, and reconfigure them for 80 TCP; 443 TCP; 53 TCP, all as per your guidance. And Enable them.
    Now, my present setup here has...
    1) My PC is wired straight to Port 2 of the Router, and has a Static IP Address set.
    My new ATV2 is hard-wired into the same subnet, albeit thru a series of switches, and again a Static IP is set. My understanding is that hard wiring an ATV automatically disables its WiFi.
    3) My wife's iPad2 is set for DHCP, so it can pick up an IP Address when on the move. It connects into the LAN using one of two WAP4410N Wireless Access Points. Ch-1 & Ch-6, with same SSID and security stuff set up on both. The WAPs in turn are wired in, again with Static IPs set. So depending where she is in the property she can connect with excellent signal strength, reaching the ATV2  by WiFi+LAN.
    On the Router DMZ is OFF, Port Range Triggering has no entries, nothing is Enabled, so is OFF. No idea about Device Discovery!
    Home Sharing is ON for the PC, ATV2 and iPad2, with the same Apple ID/Password set for each. It does work, just not consistently as it should.
    So to fully implement your idea, all I need to do is to enter these details. But I am unclear which IP Address I should put in at each new Single Port Forwarding entry field. Certainly not the iPad2, as its DHCP allocated value will change. Is it the ATV2 or the PC? Not sure, please clarify.
    BTW, I have no plan to deactivate my AVG Firewall on this PC. It is happy to pass all traffic related to iTunes, so cannot see this as a factor. Time zone same on all equipment.
    I tried with just 3689 UDP and 5353 UDP yesterday, and things were definitely better. I used 192.168.20.227, the IP Address for the ATV2.
    Look forward to your answer.
