I have this strange problem that i haven't been able to figure out. Can anyone please suggest what to try:
I have a piece of software to control my camera from my computer. It's called "Control my Nikon". It has a built-in web server. The purpose is to be able to connect from a smartphone to use it as a remote control. You choose what port it should listen to and enable it. You get a simple interface with buttons. Exposing a photo, for example, triggers the URL 127.0.0.1:8090/?c=3. Very basic stuff.
On the computer it works perfectly, but from my phone, i just get a timeout. I figured i needed to open the port (8090) in my firewall and spent some time setting that up, but it still won't work. I am using my computer's IP address on the network: 192.168.1.214:8090, which should reach the same place as 127.0.0.1:8090 from the computer.
I then set up a Spring boot application to listen to the 8090 port and i was able to reach that from the phone just fine. This suggests that the firewall is not the issue. I can trigger the control my Nikon URL from within the Spring boot application too, by making a call to http://127.0.0.1:8090/?c=3. I can also reach pages served by Apache (192.168.1.214/testpage.html) on the computer from the phone without any problems.
What am i missing here?
The Nikon software is probably binding itself to the 127.0.0.1 network interface and not every network interface it finds.
The software doesn't appear to be designed for network control but just runs a web server so it can present a UI in HTML.
You would need to change the Nikon software so it listens on other ports (or configure port forwarding or a reverse proxy).

I am doing a mobile test recording with jmeter, after i configure my mobile proxy settings to system ip and port to math jmeter. Internet stops working? P.S. i already installed the ApacheJmeterTemporaryRootCA.crt
There is a number of "mobile" operating systems and we are not telepathic enough to figure out which one you're talking about in order to provide troubleshooting instructions. I assume you use Android as it is about 75% of market.
Make sure to start JMeter's HTTP(S) Test Script Recorder prior to amending mobile device proxy settings
Make sure JMeter and mobile device are on the same subnet (connected to the same WiFi network)
Make sure that port 8888 is open in your operating system firewall
On certain Android versions you cannot set system proxy for HTTPS traffic, you will need to install a separate application like ProxyDroid for this
If nothing helps you can always consider an alternative way of recording mobile traffic, in this case you won't have to worry about proxies and certificates and you will get confidence that your device is connected to the Internet. See Testing Mobile sites and Apps article for more details.
I am very late here, but still this may help others who are still facing this issue.
In beginning i faced the same issue. Then, I tried by disabling the firewall. It worked fine.
Also disabling firewall may create a way for malicious contents to enter. Try only for trusted sources.
Got this legacy Avocent DSR2035 KVM over IP. Works! Anyone knows how I edit the TCPIP setting on this machine? I have access to the console, it works, but there is no IP settings in any of the menu!
It took some time to figure this out. I had to upgrade firmware first and that was done through the setup port in the back and using a special cable that I built. After the fw update, there were network settings in the standard interface.
How to enable Hyper-V to connect VPN for external internet access in Windows 8?
I'm trying to run Windows phone 8 app using emulator, and while see app in emulator it doesn't connect the VPN to access internet.
Please advice.
Thanks.
MSDN has a troubleshooting page for the Windows Phone 8 emulator. Perhaps you can find related info there. Something like this might help:
Cannot connect to Internet destinations
The Windows Phone 8 Emulator uses the HTTP proxy settings from the host computer. If you can’t access Internet resources from the emulator, check with your IT administrator to make sure that your proxy settings will work with the emulator.
If your network’s proxy servers are unavailable or malfunctioning, it might be possible to restore connectivity for the emulator by disabling automatic proxy detection on the host computer. However this only works in certain network configurations.
To disable automatic proxy detection on the host computer
On the host computer, open Internet Options from the Control Panel. The Internet Properties dialog box opens.
In the Internet Properties dialog box, click the Connections tab.
On the Connections page, click the LAN settings button. The Local Area Network (LAN) Settings dialog box opens.
In the Local Area Network (LAN) Settings dialog box, deselect all the check boxes. Click OK twice to close both dialog boxes.
Restart the emulator and retry the connection.
Also this MSDN blog-post can be helpful: Why can’t the Windows Phone Emulator go online?. Useful part of the article:
As you see, clicking the “>>” on the bar parallel to the Emulator will open a small window with 4 tabs. The last tab is for “Network”. To explain in simpler terms, there are two adapters here – one is for internal use by Emulator and other is for external network connectivity. Each adapter will have an IP address (IPv4) associated with itself. The one of our interest is under Adapter #2.
I have erased out the IPv4 address that is assigned to Adapter #2 (Yellow box), but you find that the IP assigned here starts with 169.254.x.x…., then Bingo! - we have figured out the problem. How?
The IP addresses starting with 169.254.x.x …. Are usually the self-assigned default addresses to a device and not really helpful to get the device to go online. This IP should either be a static IP or the one assigned by the DHCP server (if you have one in the environment) for the device to be able to connect to external networks.
Hope this helps.
I am able to hook SharePoint 2010 VHD with vmware. The central admin comes up but port 80 dont even come up. I ran into this http://blogs.msdn.com/b/steve_fox/archive/2010/06/15/rtm-demo-vm-for-sharepoint-amp-office-2010.aspx article but I dont know to perform this in VMWare Station 8. Please suggest.
Ping localhost host gives 127.0.0.1. But I get 404 both on localhost and 127.0.01
Ping to intranet.contoso.com takes a long time and i get request could not find host ....
Binding looks good too.
I am not seeing anything in IIS log . I mean nothing specific to intranet.contoso.com.
Looks like a DNS Issue to me. Try to add intranet.contoso.com to the hosts file as:
intranet.contoso.com 127.0.0.1
If this works then it is definitely a DNS issue, check if the service is running.
Also check if you actually assigned a virtual network card to the box in VMWare.
Update: To add NIC to VM Ware you edit machine settings and add hardware, add a network card as bridged. You can then manage the network card normally inside Windows.
I'm currently using cocoahttpserver to do some file sharing thing in my iPhone app. Does anyone know how to use public IP address to connect to the phone, that is to use the Internet, rather than internal connection via WiFi.
Any help would be appreciated! Thanks in advance.
Some thoughts on running an HTTP server on an iPhone:
Most of the time, with IPv4 addresses, the IP address is what is known as a “NAT” address. Simply put, the address it uses can only be accessed from other computers on the same network. It usually can not be accessed from the internet at large.
IPs can can be accessed from the internet at large cost quite a bit of money to have. They do not exist for wireless 3G networks.
Web servers like Apache and lighthttpd compile and run fine on an iPhone. However, the iPhone needs to be jailbroken before running these servers (but there appears to be a web server app for the iPhone)
Apache needs text files to be edited to be configured. It’s a great web server, but people who want to use it better be comfortable reading documentation and editing text files by hand.
