I have a Gwan server set up at home on my Arch Linux box. I'm running "motion". I have a router that, of course, handles my external IP address.
I want to access the avi movie shorts generated by motion through port 1000 which is port forwarded through my router to the box on my internal network. I've written an event_end script that copies these motion videos to my Gwan "Document Root". I've set the particular directory up according to the Gwan docs and can see these videos using the external ip address:1000 just fine when I'm at home. But when I click on the very same link from the machine at my office, I get this error message in Firefox: "Firefox can't establish a connection to the server at 99.99.99.99:1000.".
So I don't understand why I can see that link when I'm at home but not from anyplace else. What setting have I missed?
Thanks.
Are you sure that your firewall at work allows traffic on port :1000 at all?
port 1000 which is port forwarded through my router to the box on my internal network [at home]... but I get an error "Firefox can't establish a connection to the server at 99.99.99.99:1000" [from my office].
As Pete noticed, this sounds like a routing error.
As the HTTP client, Firefox, cannot even establish a connection, the problem happens before G-WAN can do anything.
while I was using quickserve, I could view those videos just fine while using port:1000
...probably from your private network at home, and not from your office.
If quickserve was available from your office then, since then, you have messed with the router port mapping OR with the G-WAN listener (hence the connection failure).
Unfortunately, since G-WAN won't receive anything until you get this right, its log files won't help.
And as you do not provide any information about your port mapping and G-WAN listener, we can't help you to spot obvious errors.
Note that this issue is a system configuration problem and has little to do with the G-WAN application server itself (remember that Stackoverflow is a Q&A site for developers). The Serverfault site might be a better place to discuss your problem.

I have an application with a server written in F# and serve web files using suave. I remote login using powershell into another machine in the network to run the application (The application is also in one of the network drives). I do that because that machine have access to third party APIs needed for the server. Now when I do [IPAddress_Of_Remote_Machine]/[html_file] or [name_of_pc]/[html_file] then chrome is waiting forever and doesn't ever return the webpage. This wasn't happening before and I ran into this problem recently. I opened a different port and used it instead of the default one 80. This made things work but the problem keeps showing up after a couple of days. I don't think it's a firewall issue but I'm clueless to why this is happening.
When running netstat -an, this is what I get (I hid the IP address):
As you can see all of the connections are either in CLOSE_WAIT or ESTABLISHED but not LISTENING. All of these TCP connections is probably because I have PhantomJS and two other APIs running in the application as well. However the loop back address is also open on the same port 5959:
I'm not sure what is difference between these two but when using PortQryUI to query the remote server it returns a success!
I have already made an inbound rule for port 5959 on the server so it should be allowed. The web page is stuck at Waiting for [name_of_pc]. Also, sometimes this problem disappears and everything works fine.
What is the potential problem behind this? Why would this happen all of a sudden?
UPDATE:
I re-ran the application today and it's working correctly. It could be that something is dynamically set within the firewall? Not really sure what is going on. The machine I'm running the server on has a bunch of applications running on it as well so maybe there is an external process that is affecting it?
I made a hello world app with Suave and deployed it on the network drive to test if it's going to work. I opened inbound rule for port 6001
Then I ran the app:
However, it's still not working and this time it says the site cannot be reached when I do: http://[name_of_pc]:6001.
Moving this to an answer so that it can be closed:
Could you post the bindings section of your suave cfg? I'm guessing you know where that is since you are using a non-standard port but if you need don't, search for HttpBinding. I suspect you will find it pointing to 127.0.0.1 which is not good enough for remote access. You could try changing it to 0.0.0.0 or to the server's actual IP address. I would try 0.0.0.0 first for the flexibility it provides
I am using openwrt and coovachilli for registration purpose, when there is presence of internet connection to router then chilli starts and popup page appears after connect to WiFi.
But I want popup page without presence of internet. Router should popup after connect to WiFi using coovachilli without internet. Please help me out in this situation.
Thanks in advance.
OpenWrt Version:- 15.05
CoovaChilli Version:- 1.3.0
It's not possible technically due to the way Coova Chilli (and other hotspot software systems) works.
Without Internet connection, your DNS server will return failures so no DNS query will work. Without DNS queries (and IP addresses as result), there won't be a HTTP request for Coova to hijack. Your device (eg. iPhone) won't even trigger a CNA window
There are possibilities (workarounds) of course - eg. make your DNS resolver (dnsmasq?) resolve to some dummy/hardcoded IP address while the connection is down. You would have to write a script yourself that detects connection and swaps configs
It is possible with a workaround.
You have to use a local UAM server (on the same host or LAN) and authenticate with local users file or local RADIUS server. For using local users file, without RADIUS server, you must specify a dummy RADIUS server IP:
radiusserver1 127.0.0.1
localusers /etc/chilli/localusers
Then, you can add a dummyuser:dummypass to your localusers file and use it for the authentication as usual:
http://${uam_ip}:${uam_port}/logon?username=dummyuser&password=${chap_password}
How can i host a website through my computer using server softwares?
I tried to host a website through my own computer using apache tomcat server but it didnt work ( please briefly explain every point )
The main issue that you need to deal with is getting the clients to your computer.
Yes, it is possible and yes I have done it, albeit a while ago.
You need to see if you can browse to your computers website from another device on your network, this will ensure that apache is working. Try another computer/laptop/tablet/whatever to see if this site reachable by other computers using the IP Address and possibly port number. If you cannot get to the site, there are settings in apache to deny certain ip's, google it to get the exact steps for your version. If it works, move on to step 2.
You will need a static IP Address to ensure that all further steps stay working, google this if you are not sure how to do it
You need to have the external IP address of your router(whatsmyip.org) or use Dynamic DNS to route traffic from an address to your ip and there are services that allow this. I can recommend no-ip.com - This is all assuming that you have access to the router.
You would be required to set up port forwarding on your router. This will direct the internet traffic to your computer. You will need to get the exact instructions for your specific model of router.
Please be aware that you need to have proper firewalls and systems in place to prevent attacks. I am sure that you are just testing at this point though...
All the best!
I installed usbwebserver
everthing is running, I am trying to reach the root page index.php?
I read everything I possibly can and sorry but I still cant figure out how to reach my localhost
I reach my page with localhost:8080 and the page I want shows up but if I replace it with IP:8080 it does not.
I am trying to reach this page outside of my local network.
I'm sorry, I need to provide you a separate answer for your reformatted question for the "down the street" scenario. I can troubleshoot a few of the issues you're probably having.
ISP's don't typically allow residential internet connections to serve resources over port 8080, or 80. Even if you were to configure your computer as needed, if you're on a standard internet service provider they're probably blocking you in the middle even if you have punched holes all your local security in an attempt to serve assets over port 8080/80.
Assuming they don't allow that you're going to have to first configure your outbound middleware(php in your case) to listen to calls into your ip on a different port. ( You can do this in your C:\WAMP\ folder, in the "wampserver" configuration file. Here's a good walkthrough here: (http://forum.wampserver.com/read.php?2,13744)
Now, you're going to have to drop any firewalls windows/ubuntu/macOS are providing on that port. (This is the part where you've rolled out the red carpet for hackers to get into your box(es) so be careful!) Here's a link for a short and sweet explanation on windows here: (http://yourbusiness.azcentral.com/turn-off-windows-firewall-19396.html) Note that you can open individual ports, you don't have to drop your entire firewall.
Make sure you have opened up access to any folders/mySQLdb's/resources to outside requests as well (seriously, this is a REALLY bad idea from an #home server if you don't know what you're doing)
Then figure out the correct ip and the correct port and give it a go! If it still doesn't work you can download a program like [wireshark] (https://www.wireshark.org/download.html) or [fiddler] (http://www.telerik.com/download/fiddler/fiddler2) to debug your inbound/outbound traffic and see what the machine's seeing before your browser/server gives you any user visible information.
One thing to note, if you are an amateur web developer your homepage is called "index.html" not "home.html" "home.html" only works fine locally, but internet browser engines look by default, for "index.html"
Lastly, and I really can't stress this enough don't host through your personal ISP and serve files from your own machine. Hosting through Fatcow, or hostgator, or any of the other hosts is really honestly dirt cheap and they know far better than you or I do about security.
That said, I hope very much that you succeed in using my answer, or at the very least learning something from it. Happy Coding!

Read the Background session
go to a command line, type "ipconfig"
Hit Enter.
Under "Ethernet adapter Ethernet:
It should be the third line down, has your following:
IPV4 Address : 192.168.1.xxx where "xxx" is your ip
address.
USE "//" + "the ip address shown for (ipv4)" plus ":8080" and your default page
should show just fine.
For example, if your cmd "ipconfig" for this process reads: "192.168.1.12"
your total URL in your browser will be "//192.168.1.12:8080"
Note that I used 2 forward slashes prior to using an IP address on your
local network. That let's your computer know it's using your network, not
the actual internet. The slashes alone may solve your problem. Also note, if you're accessing a database through your webapp, you will also need to properly configure your db settings to allow access.
First find your outside ip adress not local ip. After that go into router panel and open to use from apache server. Anyone able to access that port now. You can connect outside your local website now. If you can't do that. Try again. This is the way to doing this.
I have written a small client server socket application. It is a proof of concept for some socket programming that I want to apply to a much bigger project.
For the moment I want to user wireshark to analyse the traffic that goes between them. They are both running on my local machine.
I have installed a loopback interface, and have tried to use wireshark with it.
No joy. Any ideas?
I have successfully analysed traffic between my machine and other machines no problems.
I have had a look here,
http://wiki.wireshark.org/CaptureSetup/Loopback
And I am not using the address 127.0.0.1 which they mention saying you can't capture traffic on 127.0.0.1
Thanks.
You might try creating a virtual machine to run your application and using wireshark on it.
Save yourself some grief and download Microsoft Network Monitor.
As good as Wireshark is on Unixen, Windows is a "special" case :)
