  • Remotely port forward/launch process or a client-less remote desktop app?

    - by DC177E
    I have an XP box running Logmein at a remote location behind a linksys router, which was running well for a whole of four days, until we had a power failure. Our ISP gave us a new IP, the machine restarted, and logmein did not autorun (or, at least, it did not automatically sign in), and our service (which may or may not be a Minecraft server with non-backed-up save files) also did not run upon startup. Logmein does not register the new IP (it still displays the old one). I have a DDNS updater service, so I do know the new dynamic address. I have tried using the built in XP remote desktop service, but, as with almost all non-cloud-based remote desktop services, it requires a port forward. Thus, I would appreciate it if anyone has any ideas as to: A: Any way of accessing our router remotely to forward the remote desktop port. I've seen the Remote Management option (forwarding the setup page to port 8080), but I do not have it enabled. I've tried UPnP, but again, the setup page for our router is not forwarded. B: Any way of remotely launching a process that does not require port forwarding (or uses ports 255XX, 18XXX, or 9000.), such as a remote console service built into XP. I realize this is a near impossibility. C: A Way to remotely start logmein, and sign in, which is likely a definite impossibility. Sorry if this is too specific for Stackexchange, or if I've put it into the wrong section (is SuperUser the correct place for this?). Ideas would, again be much appreciated, as shot-in-the-dark-like this may be.

  • Trouble parsing NMEA data from Serial Port.

    - by rross
    I'm retrieving NMEA sentences from a serial GPS. Then string are coming across like I would expect. The problem is that when parsing a sentence like this: $GPRMC,040302.663,A,3939.7,N,10506.6,W,0.27,358.86,200804,,*1A I use a simple bit of code to make sure I have the right sentect: string[] Words = sBuffer.Split(','); foreach (string item in Words) { if (item == "$GPRMC") { return "Correct Sentence"; } else { return "Incorrect Sentence } } I added the return in that location for the example. I have printed the split results to a text box and have seen that $GPRMC is indeed coming across in the item variable at some point. If the string is coming across why won't the if statement catch? Is is the $? How can I trouble shoot this?

  • Socket Communication in C#- IP-Port

    - by Ahmet Altun
    I am testing my socket programs at home, in local network. Server and client programs are running on seperate machines. Server program socket is binded as: serverSocket.Bind(new IPEndPoint(IPAddress.Parse("127.0.0.1"), 8999)); Client program (on the other computer) is connected as: clientSocket.Connect(IPAddress.Parse("192.168.2.3"), 8999); Why can Client not communicate with server? Do I need to make some firewall configuration or something like that? Or am I writing Server Ip incorrectly to the Client? (I got it from cmd-ipconfig of server)

  • web apps on localhost on different ports accessed via port 80

    - by punkish
    On my laptop, with Apache I have different web apps in various directories on my laptop, that I can start using simple webservers listening on different ports. For example ~/app1/./app.pl >> listening on http://localhost:3000/ ~/app2/./app.pl >> listening on http://localhost:3001/ ~/app3/./app.pl >> listening on http://localhost:3001/ I want to access the above from my browser like so http://localhost/app1 http://localhost/app2 http://localhost/app3 Can I do the above with mod_proxy? If so, how? Update: I must add that I have Googled for mod_proxy, read the tutes on Apache's website, and experimented with the following uncommented the following in my httpd.conf LoadModule proxy_module modules/mod_proxy.so LoadModule proxy_connect_module modules/mod_proxy_connect.so LoadModule proxy_http_module modules/mod_proxy_http.so added the following in my httpd.conf <IfModule mod_proxy.c> ProxyRequests On ProxyPass /app1 http://localhost:3000/ ProxyPassReverse /app1 http://localhost:3000/ ProxyPass /app2 http://localhost:3001/ ProxyPassReverse /app2 http://localhost:3001/ ProxyPass /app3 http://localhost:3002/ ProxyPassReverse /app3 http://localhost:3002/ </IfModule> Yet, I get HTTP 404 when I try to access the above apps.

  • programmatically controlling power sockets in the UK

    - by cartoonfox
    It's very simple. I want to plug a lamp into the UK mains supply. I want to be able to power it on and off from software - say from serial port commands, or by running a command-line or something I can get to from ruby or Java. I see lots written about how to do this with X10 with American power systems - but has anybody actually tried doing this in the UK? If you got this working: 1) Exactly what hardware did you use? 2) How do you control it from software? Thanks!

  • C++ Serial Port Only Responding Once Using Write()

    - by Pfeffer
    All the code below works. My device responds, C,7 is a reset. When I run this the second time it doesn't respond. If I manually turn my device off and on, then run this script again it works. But not if I press the button to run the script the second time. RS232: 57600,8,N,1 Any ideas?? Is there any more information needed to solve this? *Also when I get this working I'm going to have to use the read() function to get the devices responses. Does anyone know the correct format I need to use, based on the below code? Sorry I'm new to C++...I'm more of a PHP guy. *I also don't know if 1024 is right, but it seems to work so eh... Thanks so much! #include <termios.h> int fd; struct termios options; fd=open("/dev/tty.KeySerial1", O_RDWR | O_NOCTTY | O_NDELAY); fcntl(fd, F_SETFL, 0); tcgetattr(fd,&options); options.c_ispeed=57600; options.c_ospeed=57600; options.c_cflag |= (CLOCAL | CREAD); options.c_lflag &= ~(ICANON | ECHO | ECHOE | ISIG); options.c_cflag &= ~CSTOPB; options.c_lflag &= ~ECHO; options.c_oflag &= ~ECHO; options.c_oflag &= ~OPOST; options.c_cflag |= CS8; options.c_cflag |= CRTSCTS; options.c_cc[VMIN] = 0; options.c_cc[VTIME] =10; tcflush(fd, TCIFLUSH); tcsetattr(fd,TCSANOW,&options); write(fd, "C,7\r\n", 1024); close(fd);

  • port an iOS (iPhone) app to mac?

    - by William Jockusch
    Is there a preferred way to go about this? The app in question is not too large . . . single-player game that I wrote over the course of a couple of months. EDIT: I should add that I have no experience with mac development . . . outside of what comes naturally with being an iOS developer. EDIT: Classes heavily used in the game: subclasses of NSObject, UIView, and UIViewController. I don't know much about NSView, but I'm pretty sure all the UIView stuff will work in that class. Also some use of UITableViewController. I do also have Game Center, but I can leave that part out for now. There is no multi-touch.

  • Unable to boot ubuntu 11.10 from external usb drive

    - by user45006
    I'm new to Ubuntu (and actually all things Linux) as of this morning, so please excuse any stupid mistakes I may be making. I recently bought an external hard drive for my newly built PC (that is running windows 7 if it matters). I would like to install Ubuntu onto the external drive and boot from there. I downloaded Ubuntu 11.10 and made a bootable cd, unplugged my internal HDDs, plugged in the external drive, installed Ubuntu 11.10 on the external drive via the installer, and replugged in my internal HDDs. Then I set my bios boot order to: Boot from USB-HDD - Boot from Hard Disk - Boot from CD/DVD. Now when I restart I get the message "Starting Operating System..." (or something like that, I forget exactly what it says) that lingers on the screen for a moment and then windows starts. Any idea what the problem may be? ~Relevant info~ BIOS version: Award Software International, Inc. F2, 2/22/2011 Ubuntu Version: 11.10 External Hard Drive: Western Digital My Passport Essential 500GB Portable Hard Drive (Black) ~Things I've already tried~ 1) Unplug internal HDDs so that only external drive was plugged in via usb. Same thing happened only obviously my BIOS could not detect any hard drives besides the external one. When booting received error "Could not detect operating system" 2) Formatted external hard drive and re installed. It didn't make a difference, however interestingly when I booted from cd the ubuntu installer said it detected ubuntu 11.10 on the external hard drive. 3) Within BIOS I've messed around with every boot order combo I could think of both in the "Hard Disk boot order" screen and the "Boot order" screen. I'm a little confused of why there are two screens for this. 4) Held F12 during startup which opens (what I think is) the one time boot screen and it gave me the options "Hard Drive", "cd/dvd", "USB-FDD", "USB-cdrom", "USB-HDD", and "USB-something else I can't remember what it was". I tried all of them, but the same thing as before happened each time. ~References~ I noticed several people on askubuntu have tried to do something similar if not the exact same. In fact, I even found a post that pretty much outlines step by step exactly what I did... only their's worked. /jealous. Linky: Install Ubuntu or Kubuntu on a External USB Drive I'm willing to try a different version of ubuntu - it's not like my heart is set on 11.10, but it's a pain to open my case and unplug my internal hard drives so I'd prefer not to do this unless someone is reasonably confident it'll work. Thank you for all of your help in advance! I'm really looking forward to exploring Ubuntu!

  • Why does USB thumb drive screw up boot sequence?

    - by Carl B
    I am looking for understanding to a boot issue. I have at times had some files and such that I save and retrieve from my thumb drive. I use the front panel as it is nice and easy to get to and I typically power down my system nightly. If I forget to pull the drive and power on the system, it becomes the first bootable device. As there is no OS on the USB Drive I get the BOOTMGR is missing press CTRL+ALT+DELETE. When I go into BIOS to see Boot sequence, there’s the thumb drive up top, DVD drive is missing and not found in the list of devices. All of the hard drives are next in line. When I pull the USB drive, and reboot, everything is back to normal. Old boot sequence is in place, DVD drive right where it should be and no issues. So why does this happen with a USB drive in port at boot up? If it can’t be booted from, shouldn’t the next drive be attempted? Note: This happens when the thumb drive is plugged into a USB port on the front panel. It does not seem to happen on rear panel ports.

  • Troubles Installing Windows 7 via USB. Flat install?

    - by Brian
    Hi friends, I've been struggling with this for a while. Windows 7 64-bit Enterprise edition just will not install on my Shuttle K45 system via a USB key. It hangs out during the install while copying files or while creating the partitions. The system is pretty standard and low-tech: IDE hard drives, no CD, 2G RAM. I am not sure what of the problem. Other than the Shuttle, I have a Apple MacBook Pro. On the MPB, I am running OS X, and Mint Linux and Window XP over Parallels. I have an ISO of Win7 that works (I installed it as a Parallels VM to make sure). I have used UltraISO and MS Windows 7 USB/DVD Download Tool to write it to the 8G USB key. Both seem to copy all the files correctly (with UltraISO, I asked it to verify). It boots via USB and the install looks just fine. Until it hangs, most of the time with a copying error of 0x80070241. So now I am trying to figure out if there are other ways I can install Windows 7 on this Shuttle system that has no CD drive. I've heard about a flat installation, however those all seem to be doing something from within Windows. I do have access to a command prompt from the Windows 7 install. Does anyone know if/how I can prep the Shuttle hard drive with Windows 7 installation and have Windows 7 install from the hard disk. I do not have an external enclosure for the IDE HD and I do not have any other system I can hook up to the hard drives. I do have an external Maxtor OneTouch drive available.

  • Why am I unable to mount my USB drive (unknown partition table)?

    - by Pat
    I'm a real newbie to linux. Anyway the problem is that my USB doesn't get recognized anymore which is really annoying because I need information from it.

  • How to set up port forwarding and firewall settings for torrents using Transmsission on Mac OSX 10.5

    - by Liz
    I have picked up bits of advice here and there on the internet and got someway through this tortuous exercise (after it took 18 hours to download the first torrent I tried yesterday - magnet-link for a film). Where I have got stuck is with configuring the firewall on the Netgear Router but I am not sure if I have caused the problem myself by something else I have done configuring the Mac System Preferences for Security or Networking. I have been following the sections of these instructions that seem to apply, although they are written for a different OSX version (don't know which one, but the screen shots do not match what I see) and I am not wanting to set up my Mac as a server and attending to the parts that apply to port forwarding for Netgear rather than LinkSys: http://homepage.mac.com/car1son/static_port_fwd_intro.html I have been trying to follow these instructions: Instructions for DG834, DG834G, DG824M, FR114W, FM114P, FR114P, FR328S, FVL328, FVS328, FVS338, FVX538, FWAG114, FWG114P, or FVS318v3 These routers do port forwarding by assigning port numbers to a "service" associated with the application you want to run. "Rules" are set for particular services. Rules block or allow access, based on various conditions such as the time of day and the name of the service. To Create a New Inbound or Outbound Rule 1. Submit the router's address in an Internet browser. (The default is 192.168.0.1). 2. Enter the router's username and password. 3. From the main menu, click Security > Rules. 4. Click Add for inbound or outbound traffic, as appropriate to the application you are planning to run. 5. Select the Service. The services the router knows about are listed in the drop down. If the service you want is not listed, add it as described in the next section. 6. Select the Action, for example ALLOW always. 7. For Send to LAN Server, enter the IP address of the local server. Note that this is also the IP address the computers on your LAN will access. 8. For WAN User choose Any, or limit access to particular IP addresses. 9. For Log selection it is reasonable to turn logs on, especially at the beginning when you are unsure of the result of the changes you are making. Later, you may want to set logs to "Never" for performance reasons. 10. Click Apply. As noted in user manual for some models: * Consider using the Dynamic DNS feature on the Advanced menu, so that external users can find your network when the DHCP lease is renewed by your ISP. * If your own LAN server uses DHCP, and your IPs change on rebooting, consider using the Reserved IP Address feature in the LAN IP menu. To Add a Service for These Routers 1. Click Security > Services > Add Custom Service. 2. Enter any name you choose for the service. 3. Select whether the service is to use TCP or UDP. If you are unsure, select both. 4. Enter the lowest port number used by the service. 5. Enter the highest port number used. If the service uses only one port number, enter the same number. 6. Click Apply. There is no "Security - Rules" submenu in the Netgear page, so I have been trying to access "Security - Firewall Rules". I can access everthing else in the Netgear settings as Admin but I cannot get the "Firewall Rules" section to open up. (I am not 100% sure I will know exactly what to do if and when I do get it opened up!) I haven't managed to find though searching the internet any instructions that would seem to apply specifically to what I am trying to achieve, so would be very grateful if someone could either point me in the right direction or give me some advice directly. Best wishes, Liz

  • Windows Firewall: How to allow traffic on port 8080?

    - by Chadworthington
    I am trying to configure team Foundation Server so that 1) it is accessible from within my Home Network 2) and then make the Web site access accessible via the Internet I have a problem with point 1: When I access http://192.168.1.106:8080/tfs/web/ locally from 192.168.1.106, it works. When I access the same web site from another PC in my home network, the abive URL works only if I turn of the Firewall on 192.168.1.106. Can someone please tell me specifically how to allow traffic on port 8080 without turning off Windows Firewall? It seems that the exceptions that I specify are intended for listing programs on the box that need to communicate out. Is IIS the program that I need to make the exception? How do I specify that port 8080 traffic should be allowed for web site traffic on this port? I hope to have success with pt. 2 later but I figure (1) should be done first. I expect issues.

  • Alternate port numbers for Supermicro IPMI View software

    - by MC9000
    I'm using the IPMI View software to manage a SuperMicro server but would like to use alternate port #s within the program itself. In other words - If I use the web browser, it defaults to port 80 - While I can, say change that port to 12345 (or whatever) and type the IP address into the browser (like http://xxx.xxx.xxx.xxx:12345 ) that works just fine. However, in IPMIView, it will assume port 80 and load the browser with the IP (which, naturally, won't work, so I have to manually type in the alternate port #). I can deal with that. The clincher is if I use a port other than 623 for management - (say 55623 for example), the IPMIView will not find it. Same goes for the iKVM port #. Is there some place to specify this (to tell IPMIView to use the alternate port numbers), like a settings file? I'm running this from a Windows client.

  • Connecting to named Instances Using Port Number

    - by blakmk
    I came across an interesting situation where a developer was trying to connect to a named instance using a DNS alias without specifying the instance name. Coincidently though he remembered to include the port number and miraculously it worked. So it appears that sql server accepts connections to a specific instance based on its port number. While it may not seem to particularly useful, I can imagine it could be used in the following situations: To mirror to a server with a different instance name (but same port number) To hide the complexity of instance names from end users and just rely on port number (and optionally dns alias)

  • How can I port forward with an airport extreme and a NAT enabled modem?

    - by Jon
    I run an Actiontec HD701D modem with NAT to an Airport extreme base station to laptop etc. As you might expect I get double NAT issues. I tried a lot of different things to forward a port, but no luck. Currently the airport is in bridge mode letting the modem handle the NAT, but still can't forward the port. Also to note: firewall is off on the router, firewall is set to allow the application in OSX 10.6.3 and I did forward the port in the router. No luck.

  • Win server 2008 change port of RD Gateway

    - by Mel
    Is it possible to change the port used by RD Gateway. I know its integrated with IIS and it uses port 443 (SSL) so i've changed my IIS bindings to use a different port for SSL communications. however, I can't find any way to specify the RD gateway port in the RD client. Has anyone ever done this before? Reason I'm asking is, my ISP just recently blocked port 80 and 443 so I am forced to use another port.

  • How to restrict ssh port forwarding, without denying it?

    - by Kaz
    Suppose I have created an account whose login shell is actually a script which does not permit an interactive login, and only allows a very limited, specific set of commands to be remotely executed. Nevertheless, ssh allows the user of this account to forward ports, which is a hole. Now, the twist is that I actually want that account to set up a specific port forwarding configuration when the ssh session is established. But it must be impossible configure arbitrary port forwarding. (It is an acceptable solution if the permitted port forwarding configuration is unconditionally established as part of the every session.)

  • Can I pass HTTPS traffic from one port to another?

    - by Kit Sunde
    I'm doing a proxy_pass in nginx on port 80 to 8000 on my remote server, and then a port forward from 8000 to 80 from the remote to my localhost. This works great, but I'd also like to do it with https but it seems like nginx needs a valid cert to pass the traffic on. Is there a way for my remote server to simply forward the trafic from port 443 to say 8443 (and then I'll forward remote 8443 to local 443). Then terminate ssl on my development machine instead instead of needing to do it on the remote server? My remote runs ubuntu and my localhost runs osx.

  • Software to create a virtual parallel port in Windows XP?

    - by drknexus
    I am writing a program that will eventually be used on a computer with a physical parallel port and will need to set certain pins high or low in order to signal to an external device. However, the development laptop I am using does not have any physical parallel ports and is too low powered to run a virtual machine. Is there any option available that will create a virtual parallel port within Windows XP? Ideally it would include a debug mode that would allow me to see what values have been pushed out on the parallel port.
