Ports with routers

Ok here is whats going on.
I have made a program that connects to another computer via IP using the socket 4444. This works all good in network but when i connect to computers out of network i have to have the computer that is running the server program make the router forward the 4444port to that computer. Whcih i have done and it works.
what im asking is there anyway to connect to a computer that uses ar router and that computer does not need the ports forwarded to that computer.
sorry if it seems a bit confusing thx in advance

It would be possible if the server had a public ip-address. But the reouter is there to protect the server so you should not try to get around it.

  • How to use thunderbolt port with disks and DVI-display

    Hello,
    today I use a 15" MacBookPro and have attached 1TB LaCie with FW800  (for time machine) and DVI-Display using Mini-port.
    Need to add more external disk space and look for Lacie 2 TB with thunderbolt connection (for storing mass of pictures in Raid1 version)
    Is it possible to connect the new disk, the other disk with an Thunderbolt->FW800 adapter and the DVI-Display to one thunderbolt port?
    What are the options I have, to get all three to work at the same time?

    No, or at least not without additional hardware. You have too many end-points for one Thunderbolt chain.
    You also have the problem that the Thunderbolt->FW800 adapter is not yet for sale.
    If the new disk you get has two Thunderbolt ports (which not all do), you could daisy-chain the Thunderbolt->FW800 adapter behind it, but that adapter has to be at the end of the chain. The Mini-port->DVI adapter likewise needs to be at the end of a chain.
    So, you can probably get all three connected at one time by connecting the "1TB LaCie with FW800  (for time machine)" to your FW800 port, while connecting the Thunderbolt->FW800 adapter (when available) to the second port of the new disk. I say "probably" because nobody has the TB-FW adapter yet to try it.
    As for doing it on one Thunderbolt port with additional hardware, you might look into third-party docking stations being released in the next few months. The announced prices are in the low-to-middle hundreds. I won't mention brand names, as this is an Apple forum, but they aren't too hard to find by web search.
    The highest-priced solution would be the Apple Thunderbolt Display, which gives you a FW800 port for your 1TB drive, a pass-thru Thunderbolt port for your new disk, and of course a 2560x1440 display (plus ethernet and usb2 ports you may not need). It's available now, in the uppermost hundreds. There are some refurbs in the online Apple Store at the moment at 15% off.

  • Possible to use old macbook (mini dvi port) with 24 in LED display?

    Is there a combo of adaptors that will allow me to use my older macbook (mini-DVI port) with the new apple LED screens- i.e. adaptors allowing mini-DVI to mini displayport connector that comes with monitor?

    You need this component and a mini DVI to DVI adapter.

    - Try restoring the iPod, first from backup and then try to factory settings/new iPod to rule out a software problem.
    - Look at the dock connector on the iPod. Look for abnormalities like bent or corroded contacts, foreign material and broken or cracked plastic.
    - Could you have damaged something when you took the iPod apart and replaced the Home button?

  • Cant use DVI-D port with DVI-D cable from Pav 500-100a to HP W2207 monitor

    I have a new Pav 500-100a factory standard with no mods.  A HP w2207 monitor.
    Currently connect fine with VGA to the DVI-D port with the adapter that came with the pc.  I've setup Windows, updated to 8.1, put in my files from my old PC and all was well except video isnt that good.
    I got a DVD cable form work but its a DVI-I cable.  It took 5 mins before windows comes up and then whenever the background picture changed in the theme it hung for a few seconds.  I read that I need a DVD-D cable which i purchasd today.
    The packet says its a CL-DVI2M - DVI M/M 24+1 CABLE 2M.  The tech in the shop says its a good calbe and will work fine.
    When connected and I power up I get teh hp logo and rolling dots then it goes blank.
    I reconnect teh VGA cable and its all fine - using the VGA to DVI adapter.
    I ran msconfig and turned of safe boot - restarts and comes up fine in safe mode.  I set the resolution to 1280x800 and restarted and reconnected the DVI cable - blank again.
    If I put the VGA cable back in it boots fine.  The monitor has been factory reset and seens the DVI connection but Windows remains blank. Also tried booting first with no cable - connect teh DVI and the monitor remains in sleep - power reset teh monitor and still blank also shows no DVO conenction.
    I fI power up with DVI connected I can get to BIOS, and i see the HP logo and dots as Win 8 starts.
    I dont know what else I can try.  I have no other usable video card with DVI
    Any ideas out there?
    Pls help - Steve

    Hi Steve,
    Only connect one active video cable to the monitor and do not use any adapters.
    Use a flashlight and examine the DVI connector on the monitor.  Which DVI type is it?
    Some of the older HP monitors have DVI issues so you might want to check with HP Support and see if you have one of those models.
    An older post a long time back indicated that audio also had to be feed to the monitor (claimed by a poster).  If this is indeed true then it's a monitor design flaw. So, you could use a native HDMI cable and test out that claim.

  • How can i output a voltage on PCI-6229 port with visual basic 6 ?

    Hello,
    PCI-6229 card is using DAQmx, that not support VB 6 officially.
    However, members of this forum found out a way to write/read on digital port with vb6 and DAQmx.
    This was working well for me indeed.
    Then, i wanted to output a voltage on AO. I followed the same procedure they used for DI/DO but in vain.
    Apparently, the function DAQmxCreateAOVoltageChan()* causes trouble.
    Using the .exe of the program, i get this error :
    "error -200077 : Requested value is not a supported value for this property."
    Thank you for any ideas that can sort this out.
    * Public Declare Function DAQmxCreateAOVoltageChan Lib "nicaiu.dll" (ByVal TaskHandle As Long, ByVal lines As String, ByVal nameToAssignToLines As String, ByVal min As Single, ByVal max As Single, ByVal units As DAQmxUnits, ByVal customScaleName As String) As Long

  • I need lots of USB ports with New Mac Pro, now what?

    because I'm in the audio business I needs lot of USB ports with my Mac Pro. On my current 2008 machine, that's not really an issue, with 5 ports on teh MP itself and I installed some USB hubs over PCIe that give me a total of 13 port. I'm not really sure what is the best way to get that amount on the new MP.
    Oh, and I really like the stability of my current set up. Before I went with an external USB Hub that always gave me headaches with ports not being recognized.

    The only two things I found so far are:
    a/ going back to the external USB hubs, which I find very frustrating to work with, because instable with connection and I would need to add some interface to go from USB to TB (which are also rather expensive at the moment)
    b/ use some external PCIe enclosures that are really expensive.
    So I havent really found the right solution for my situation. Which makes me hesitant to migrate to new MP at the moment.

  • No hdmi port with this laptop?

    No hdmi port with this laptop?

    Only some laptops HDMI ports - of current models, the MacBook Pros do and the Macbook Airs don't. You can get adaptors from Thunderbolt (or Displayport on an older laptop, the plug is physically the same) to HDMI: for example this one.

  • 802.1x per host authentication under one port with multi-host access by hub

    Dear,
    While multi-host connect to one port by hub, it seems that in multi-host mode, after one host passed the authentication, the port change state to up, and the other hosts do not need to authenticate any more. And in single host mode, only one host could access to the network under one port.
    In the situation with multi-host access to one port by hub, is it possible that we could control per user access by authentication for each?
    We did some test on 3550, it seems that the 3550 doesnot support what we need. And what about 4506?
    Thanks!

    Multiauthentication Mode
    Available in Cisco IOS Release 12.2(33)SXI and later releases, multiauthentication (multiauth) mode allows one 802.1X/MAB client on the voice VLAN and multiple authenticated 802.1X/MAB/webauth clients on the data VLAN. When a hub or access point is connected to an 802.1X port (as shown in Figure 60-5), multiauth mode provides enhanced security over the multiple-hosts mode by requiring authentication of each connected client. For non-802.1X devices, MAB or web-based authentication can be used as the fallback method for individual host authentications, which allows different hosts to be authenticated through different methods on a single port.
    Multiauth also supports MDA functionality on the voice VLAN by assigning authenticated devices to either a data or voice VLAN depending on the data that the VSAs received from the authentication server.
    Release 12.2(33)SXJ and later releases support the assignment of a RADIUS server-supplied VLAN in multiauth mode, by using the existing commands and when these conditions occur:
    •The host is the first host authorized on the port, and the RADIUS server supplies VLAN information.
    •Subsequent hosts are authorized with a VLAN that matches the operational VLAN.
    •A host is authorized on the port with no VLAN assignment, and subsequent hosts either have no VLAN assignment, or their VLAN information matches the operational VLAN.
    •The first host authorized on the port has a group VLAN assignment, and subsequent hosts either have no VLAN assignment, or their group VLAN matches the group VLAN on the port. Subsequent hosts must use the same VLAN from the VLAN group as the first host. If a VLAN list is used, all hosts are subject to the conditions specified in the VLAN list.
    •After a VLAN is assigned to a host on the port, subsequent hosts must have matching VLAN information or be denied access to the port.
    •The behavior of the critical-auth VLAN is not changed for multiauth mode. When a host tries to authenticate and the server is not reachable, all authorized hosts are reinitialized in the configured VLAN.
    NOTE :
    •Only one voice VLAN is supported on a multiauth port.
    •You cannot configure a guest VLAN or an auth-fail VLAN in multiauth mode.

  • Is it possible to control the parallel port with Lookout 5.0

    I want a simple demo setup on a PC, so I can control the 8 data bits of the parallel port. Example, to use START p/b that would toggle bit 0 and data returned on bit 1.

    It is possible to send bytes to the parallel port using the ASCII object within Lookout. However, it is presently not possible to control the state of the individual bits on the parallel port with Lookout.
    If you need to control the individual bits on a parallel port, consider using LabVIEW. It is much more powerful when programming serial and parallel ports.

    I have tried to move the card to another port with no luck.Ran all the updated software possible. Please can someone advice

    Hi,
    Was the card previously working in that machine? If it was and you have a G5 tower you could try the card in there. Here is a list of Apple fibre cards and cables which show what's compatible with what. http://support.apple.com/kb/HT1769
    The card should appear in the System Profiler under Fibre Channel and PCI Cards.

  • Airport Extreme Simultaneous Dual-Band port forwarding broken if only TCP ports with firmware 7.6.1

    When configuring my Airport Extreme Simultaneous Dual-Band router, port forwarding is broken if you only specify TCP ports to forward. This is with firmware 7.6.1. What happens is that after you hit the Update button, when the router comes back and you open the port forwarding entry, the IP is still there but the port numbers are missing.
    I tried all different port numbers and ranges and nothing would stick if i only specified TCP ports. If i added UDP ports with the TCP ports then it would save them. And if you add a new entry with only UDP it saves them too.
    Now this is with adding a new port forwarding. I already have existing ports being forwarded that only have TCP. They are still working. I believe i added them with a previous version of the firmware.
    Any one else see this issue? Any ideas?
    Maybe i should perform a hard reset and reload a saved config.
    Peace,
    Dan

    I haven't seen the issue but you could just downgrade to an earlier firmware:

  • Is using COM ports with crossbridge possible on adobe air desktop?

    or is there any other way of accessing COM ports with adobe air?

    You should be able through the air native extension Native extensions for Adobe AIR | Adobe Developer Connection
    I doubt that what you need here is CrossBridge. If there is a way to do it from normal AS3 AIR though, you will be able to do it from Crossbridge too. Maybe not the same way you would too in normal C++, but since you can go back and forth from c++ to as3, that would work.
    Search for air instead of crossbridge and you might find something.
    I sees some posts about it on google, for example: Air serial port connection
    But personally, I would do it in C++ with the native extension if there is no library that already do it for you.

  • Why can't I extend my wired TC port with linksys switch?

    Why can't I extend my wired TC port with linksys switch?

    Temporarily, connect a laptop to one of the LAN <-> ports on the TC using an Ethernet cable. Turn off wireless on the laptop. Can the laptop connect to the Internet?
    If yes, you know the port is working and the Ethernet cable is working.
    If yes, connect the switch to the same Ethernet cable. I assume that you are using an "unmanaged" switch. Some switches may need to be powered off and restarted.
    If no on the first test, try another Ethernet cable that you know is working. Try another LAN <-> port as well.
    The whole idea is to start at the TC and work outward step by step, checking each connection and step along the way.

  • Unity Connection 1.2(1) which has SCCP ports with CallManager 8.5(1)SU1.

    For 24 hours I’d like to run Unity Connection 1.2(1) which has SCCP ports with CallManager 8.5(1).  Unity Connection 1.2 isn’t supported anymore, we are migrating to Unity Connection 8.5(1) but I wanted to do CallManager 4x to 8x upgrade the first night, and Unity Connection 1.2 to 8.5 upgrade the second night. All new hardware so using DMA and COBRAS.
    I'm not looking for it to be "Supported" just want it to work 24 hours while migrating...
    Unity Connection 1.x Compatability Matrix will likely never show CallManager 8.5 since UC 1.x is EoL

    The primary factor in the integration here for SCCP is the TSP version.  You can verify the version of TSP running on Unity Connection with the procedure noted here:  http://www.cisco.com/en/US/docs/voice_ip_comm/connection/1x/release/notes/121sr2ucrn.html#wp37944
    It's a Windows box so the procedure is the same as with standard Unity.  Check the properties of AvSkinny.tsp in the \Windows\System32\ folder path.
    If you don't care about official support and it's only temporary then I'd say check to ensure that TSP is fairly recent and, if needed, upgrade to the latest release available for install on CUC 1.2(1).  Run a number and tests and make sure 1) things function as expected and 2) you don't get a load of TSP errors in the system/application logs.
    Cisco notes that product support is based primarily on testing and since Unity Connection 1.2(1) is outdated and CUCM 8.5(1) is brand new, it's not likely that this combination will be tested anytime soon ... but the TSP compatibility between 8.0 and 8.5 is likely to be similar if not the same.
