Using TCP on the second ethernet interface

Hello,
I'm using a PXI 8109 running Pharlap.
I'm trying to use the second ethernet interface of my PXI to send UDP and TCP packets. The primary interface is used to manage Veristand Channels.
Here is the configuration of my two ethernet interfaces: 
- eth0 (primary):
IP : 10.0.0.3
subnet mask : 255.0.0.0
- eth1 :
IP : 192.168.10.9
subnet mask : 255.255.255.0
For UDP, I have no problems, packets are sent to the second interface as I want. I think it work because there is a "network address" input on the "UDP Open" VI so the system can choose the right interface.
For TCP, I use the "TCP Open a connection" VI but there is no this kind of input. And it is not working : I assume the system is trying to use the primary interface but it can't route packets... 
For information, my two networks are physically independant.
Can you help me finding out what's going on ? Is it possible to use TCP on the second ethernet interface ? 
Many thanks,
Regards,
Laurent

  • Second ethernet interface ni a cache engine

    I'm trying to configure the second ethernet interface
    in a CE 505, version 2.51
    a "show hardware" command shows 2 ethernet interfaces, but when I go into configuration
    mode and try to set any parameter in the second
    interface, I get the error:
    "configure interface 1 denied"
    Thanks for any clue.

    Hi
    On a CE-505 you cannot use the second interface. This is a limitaion of the software on the device. Only if you had a content engine running version 3.x or 4.x can you use the second interface.

  • Using ports of the same network interface

    Hi,
    I'm an Oracle DBA.
    I will perform 2 installations of Oracle Management Agent on a Solaris server with the following config:
    SunOS 5.10
    Interface IP Address Hostname
    ce6 address0     hostname0     
    ce6:1 address1     hostname1
    ce6:2 address2     hostname2
    The first installation will be done on <hostname1>.
    The second one will be done on <hostname2>.
    Each agent will use a port that defaults to 3872.
    Can I use the same port 3872 for both installations?
    Thanks and regards,
    Giuseppe Centioli

    Hi Darren.
    netstat -an | grep 1831
    <hostname1>.1831 <hostnameX>.1399 63980 0
    50400 0 ESTABLISHED
    *.1831 *.* 0 0
    49152 0 LISTEN
    Okay, that's incorrect. You'll see that the process is listening on *.1831. In other words, it's listening on all network addresses. That was the specific point I was making earlier. It must not do that. The listener must bind only to the network address chosen.
    When it's set up right, you should see a specific address on the LISTEN line, not a *.
    The error is an Oracle related error telling
    that another LISTENER
    has been started with port 1831.Yes, that's the case here. The listener is not binding to the correct address in your configuration. I am not an Oracle DBA, and I can't tell you what the correct syntax is.
    Hmm. Okay, here's some stuff from google. Do you have a hostname specified in your listener.ora file?
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521))
    Like that?

  • Automatically starting DHCP on second ethernet interface in Solaris 8?

    Hello,
    In my current setup, I have a Solaris 8 server with two ethernet interfaces - elxl0, which is connected to my internal network and has a static IP, and elxl1, which is connected to a cable modem and gets its address via DHCP.
    When I reboot the machine, it brings both interfaces up, but does not start DHCP on elxl1 automatically. I have an empty /etc/hostname.elxl1, which I thought was supposed to tell the OS to use DHCP for that interface. I have to manually tell the interface to get an address using ifconfig auto-dhcp start.
    Is there a way to tell the OS to use DHCP for elxl1 without disturbing elxl0? It would make things significantly more convenient for me, since now I have to manually start DHCP, and then reload my IP Filter NAT rules.
    Any assistance you could provide would be greatly appreciated. Thanks!
    - Brad Williams

    I figured it out.
    What you have to do is add a file, /etc/dhcp.<interface>, in order to make this work. In my example, the file would be "/etc/dhcp.elxl1".

  • Photoshop Touch crashes after using adjusments for the second time

    I am having a similar problem.  When I select a portion of an image,  then try and make some adjustments,  it crashes on the second adjustment. Specifically,  I used the selection tool,  then selected the inverse on the selection.  When I tried to change the saturation after adjusting the brightness,  it crashed.
    It did this on several different images and after clearing the ran and resetting the phone. It is really irritating because I have not been able to save one image so far because it has crashed every time.

    I am using the scribble selection tool to isolate a a person in a photo.  Then I inverse the selection and desaturate - and I have tried just using the black and white adjustment - the rest of the photo. The problem comes when I inverse back to the person and try to adjust the selection. I can usually do one adjustment,  then it crashes on the second adjustment.  It has crashed everyone I have tried a this with different images and after resetting my phone
    My ram was about a gb when this last happened.  I am using a galaxy note 2.

  • Using brochure template, the second side prints upside down.  How to fix?

    When using the brochure template how does one correct the back page from printing upside down?

    Hi,
    From the application used to print open the printer dialog, then click on ettings or Preferences to access to Printig Preferences dialog.
    Within the Layout tab change the Print on both sides option.
    For a portrait oriented document select Flip on Long Edge, for a Landscape one select Flip on Short Edge, then it will print as expected.

  • Why can't I send any more than 5 TCP messages per second on an NT system?

    Help!
    I am trying to send a message (approximately 50 bytes long) every 22 ms (45.4 Hz) to the only other machine on our network (the server). I am using the following function:
    Status = ClientTCPWrite(Conversation_Handle, Pointer_to_the_data, Size_of_the_data, Timeout_value);
    I have tried various values (0, 1, & 10) for the Timeout value to no avail. The status always comes back saying it wrote fine (no error status). I am running this application on Windows NT 4.0. No matter what I have tried it can only muster about 5 messages per second. I think NT might be limiting me, but I'm not sure. I am updating the screen (which ought to take longer than writing the messa
    ge) every time I send with a count of how many messages I have sent. This appears to be working at the proper rate (I am using a timer set to go off every 0.022 seconds to call the send). I am the administrator on this NT machine with all rights (as far as I can determine). I have tried using the SDK function SetPriorityClass to set the priority of this task to REALTIME_PRIORITY_CLASS, but the return value comes back 0, which means it was unsuccessful. I haven't explored this any further yet, but 22ms should be a long time to a computer so it ought to work without having to go to these extraordinary measures (at least that is what I think). Anybody familiar with the inner workings of NT or the TCP library PLEASE RESPOND.
    Thanks,

    22ms is a long time for your computer, but I am wondering about your network. Are you 10 base or 100 base? Switch or hub? Have you tried a direct connection with a crossover cable? Just trying to spark ideas here. I use TCP all the time but only at 500 ms intervals.

  • Directing traffic to second ethernet port

    Hello,
    What is the process used to direct certain IP addresses or a range of IP addresses to the second ethernet connection on a Mac Pro? I have a set of Mac Pros that use the first connection for internet access and corporate server connections using Samba. But the second ethernet connection is used for a lan between the Mac Pros and printers. It currently works but it take a bit for the "connect to servers" dialog to connect to a Mac Pro on the lan because I think it is searching Connection 1 first which has hundreds of Windows servers attached to it. And it takes several minutes to connect if our service has an interruption on Connection 1. All of the Mac Pros and printers are set up to use a manual IP address (192.168...) The Mac Pro workstations use Snow Leopard and we have a Mac Pro Server running Lion Server that we use to conntrol a network RAID. Thanks for your help.

    Thanks guys.
    First, it seems to me that the service order is already set up correctly. I have Connection 1 on top and that's what we use for internet connection. If I change Connection 2 on top our internet connection is disabled. Also as Grant suggested we do have it set up to use different IPs and subnets. Connection 1 uses DCHP and has a static IP of 172.x.x.x and a subnet ending in 128. Connection 2 is set up manually with an IP address of 192.x.x.x and a subnet ending in 0.
    I would just like to tell each Mac Pro when it trys to connect to a server with an IP of 192.x.x.x to use Connection 2 instead of trying to find it first on Connection 1. The AppleScript within an Automator program that we use to connect to servers is:
    tell application "Finder"
                        open location "afp://[username]:[password]@192.x.x.x:548"
              end tell
    Make sense? It has been suggested to me that I set up persistent routes, but I haven't found a solution online that matches our senario enough to implement it. Any ideas? Thanks again.

  • Second ethernet port functionality

    I was wondering if/how one can use the second ethernet port on my G5 to connect a second computer to the internet? So in other words I want to use the G5 to "pass through" to the network, and beyond. Now I have two complications (and no doubt big ones)
    1) I am connected to a windows network
    2) It is a windows operating system on the laptop.
    (There are programs on the PC that don't run on the Apple. So I am stuck.) Any suggestions would be much appreciated.

    thank you for helps Ling Davis,
    ı hope this information is clear.
    ı have a problem about connection to LAN ,ı wanted to use both to ethernet ports. ı can connect with first ethernet port but second one is not available.By the way , ın network settings it's shows that both connections are available.

  • Two email accounts - iCloud wont let me open the second one!

    I have two me.com email accounts. One of them is my main account and I use the mail App to use it. The second account I use only occasionally and I have always used it with a browser. Now whenever I try to open this account in my browser I get a message saying "Your Apple ID must be used to set up iCloud on an iOS or OS X device before you can use iCloud.com" What does that mean? I cant access that email account anymore!  :-(

  • Triggering main window of the second page

    Hi Experts,
    I have two pages. Second Page will only get trigger at certain condition. I am triggering the Second page through Command. My issue is my second Page is triggering but the main window of the second page is not getting triggered. It should be like that the main window should get triggered. Even I have copied the main window and used it in the second page that is also not getting triggered. Please help me to resolve this issue.
    With Regards,
    Anomitro

    Hi,
    You should not create a new main window in the Second page of the smartform
    Instead, you copy the main window of the first page to the second page.
    So even if you add a text window in the first page Main window that will be reflected in the second page, but this should be below the command window.
    Use the command window to trigger the second page.It triggers the second page and all the text windows that are after(under) the command window will be coming in a new page.

  • How to make a cell that recognized the second from last?

    Two tables. First is data and second refers to the second to last column of the first which is always changing. The first table is a weekly table so it is constantly expanding. On that first table has a number that changes with it. I want the second table to show that changing number.

    since i have added, table 2 will still be showing C3 since i, at the time, set it to show the, then current, total.
    Is there a way to make table two always refer to the the last column of the 3 row?

    Hi gaksdd,
    I am feeling bad. I am afraid that your spreadsheet will be ungainly and cranky and hard to update in the future. I want to say this much at least: Numbers tends to work best when the tables are longer than they are wide. I don't expect you to have this problem but while tables can have potentially thousands of lines they cannot have more than 256 columns. Many things will tend to work better if you orient your tables this way. As you are just beginning it makes sense to develop good habits and start thinking more like the program designers expect. It will pay off. If you ever decide to use iOS forms for data input they are designed to input data one row at a time. If you are inputing more than 1 number a day it would make sense to reorient your data table so the weeks run down the page.
    INDEX(range,row-index,column-index,area-index)
    You have specified a range.Then the first comma.
    row-index is where you specify a row. In my example it was "2" for the second row in the range. This is where you would use ROWS(), before the second comma.
    column-index is where I used COLUMN(). then the third comma.
    We don't need area-index.
    I get a certain pleasure in pushing this program in unusual ways and this certainly qualifies. It is not a best practice.
    When you have your formula working, compare it to
    =SUM(Table One::2:2)÷2 or the variation needed for your table. This way of working makes your report table more reliable.
    Simpler is more robust, less likely to bite you in the butt down the line.

  • Vfc interface down until "shut/no shut" on Ethernet interface(s)

    Hello, I'm hoping someone out there has had this problem and knows the solution, or can provide some insight as to whether the problem is with the CNA, Host OS, or Nexus.  I've not yet posted anything to the Brocade discussion forums about this issue.
    I have vfc interfaces that are not coming up naturally; the log states that it fails "waiting for flogi" (see 'google').   The only solution that I've found posted for that problem is to apply the QoS settings for FCoE.  Those settings were already applied during the initial configuration of the switch, and I've since double and triple checked them.  I've also gone through the Cisco Nexus 5000 Troubleshooting Guide, Troubleshooting FCoE Issues, and everything checks out except a couple of things:
    1)  The interfaces don't get past the FIP Solicitation stage: They show Triggered Event: [FCOE_MGR_VFC_EV_FIP_SOLICITATION] over and over again.
    2)  While the troubleshooting guide states that the FCoE vLAN should be STP forwarding on the underlying Ethernet interfaces, it is not.  However, I have a working configuration elsewhere (with different make/model CNA hardware and Nexus software revisions) and the FCoE vLAN is not STP forwarding on those underlying Ethernet interfaces either.
    The interesting part is that if I do a "shut" then "no  shut" on the underlying Ethernet interfaces, after the hosts have  completely booted, the vfc interfaces come up and successfully register in the flogi database.  At that point everything is functional.  If the hosts then reboot, the vfc  interfaces fail to come up until I perform the "shut/no shut" on the underlying Ethernet interfaces.
    One other noteworthy symptom is that during POST, when the CNA initializes, it displays the error message "Link initialization failed. Disabling BIOS."
    Here is a configuration synopsis:
    Cisco Nexus 5548UP [Ver. 5.1(3)N2(1)]
    Brocade 1020 CNA [Rev. 3.2.1.0]
    ESXi vSphere [Ver 5.1], [CNA Driver Rev. 3.2.1.0]
    There are two vSANs; A-side and B-side.  Each is bound to a unique and dedicated vLAN.
    Po1 is the vPC peer-link.  The FCoE vLANs are *not* allowed on it.
    Po1011 is DB1's vPC port-channel.  It is an 802.1q Trunk; the native vLAN (1) and the FCoE vLANs are allowed, among other Ethernet data vLANs.
    Po1021 is DB1's vPC port-channel.  It is an 802.1q Trunk; the native vLAN (1) and the FCoE vLANs are allowed, among other Ethernet data vLANs.
    vfc1011 is DB1's Virtual FC interface.  It is a Trunk (mode TF), allowing the A-side vSAN only.  It is in the vSAN membership database.
    vfc1021 is DB2's Virtual FC interface.  It is a Trunk (mode TF), allowing the B-side vSAN only.  It is in the vSAN membership database.
    EDIT:  The Port-Channels are LACP.
    Thanks for your time.
    Message was edited by: Michael Hertrick

    I agree that the more distance you can put between the fabrics ever converging into one, the better off you are.  You don't want faults on one SAN to interrupt and cause faults on your redundant SAN.
    Nevertheless, the aforementioned configuration does not converge the two vSANs. 
    The host does not bridge between the two adapters, nor do the switches bridge between the two.  Remember, even though you bind the vfc to the port-channel in the configuration, the vfc is really bound only to the Ethernet interface on the local switch and is not participating in the port-channel at all.  There is no way, with that configuration as-is, for SAN A traffic to land on SAN B.  A series of a few mis-configurations would be required for the SAN segmentation to be eroded. 
    http://www.cisco.com/en/US/prod/collateral/switches/ps9441/ps9670/configuration_guide_c07-543563.html
    See sections "Configuration Parameters That Must Be Identical" and "Configuration Parameters That Should Be Identical"
    Under "must" there is:
    Enable or disable state per VLAN"
    Under "should" there is:
    Spanning Tree Protocol interface settings: 
    VLANs (Rapid Per-VLAN Spanning Tree Plus [PVST+])
    Would you mind pointing out in the document you linked where Cisco recommends that the allowed vLANs on each side of the vPC should be different?  I didn't exactly find that.  What I did see was that they have vlan 101 and 102 allowed on both port-channel11 and port-channel12 in their example.  vsan 101 is bound to vlan 101, vsan 102 is bound to vlan 102.
    Kind Regards.

  • Can I use the second TCP / IP port on my cRIO to drive a meter Agilent

    I would like to use the second TCP / IP port of my NI cRIO-9024 to control my Agilent 33210A pulse generator with VISA TCP/IP.
    My Agilent has only TCP/IP and GPIB ports.
    Is it possible?
    cordially

    All the MACs (from my old 2006 PPC Mini) will auto detect ethernet crossover and straight through and rollover cables correctly. They should be Auto-MDIX.
    Having said that, the FW800 (via TB) and Ethernet should be very close in terms of performance.

  • Use of the second interface

    Hi,
    I just configured the first interface of my C150 ESA with ip address, default gateway,listener, RAT and SMTP routes. I want my IronPort to handle mail for another domain with a totally independant netwotk (subnet and mail servers...). Can I configure the second interface the same way I configured the first one (obviously with all the good settings...;-)) ? Does it work? Is there no problem of IP or SMTP routing ?
    To be short, I want to do two "one interface configuration" scheme with my ESA (which has two physical interfaces) and not a "two interfaces configuration" scheme
    Thanks,
    Vincent

    Vincent - should be ok to do this. You have two options to do this:
    1. Use the 2nd NIC port and assign IP.
    2. Use the virtual gateway feature to get this 2nd IP address onto the network and then create a new listener on the virtual interface..this is much simpler and less work.
    Use the interfaceconfig CLI command or in the GUI to do this. Bind the new interface with it's unique DMZ ip onto the same network card as used for the previous interface (data 1 i assume).
    Option 2 is much easier
    :wink:
