I'm trying to deploy a web application based on ASP.NET to Apache/mod-mono
The application is for my personnal use only as it is not safe at all : I have to access to a serial port of the web server !
When I run my application on windows (with the server in VS2010), everything is going great, I can have access to the serial port and communicate through it, but things are going bad when I try it on a Apache server. My web application has a proper behavior, but I get an Internal Server Error when I try to access to the serial port.
I think the problem comes from a lack of permission for the server to access to the serial port, but how can I overcome this issue ?

I am new to WCF Services, I have developed a WCF service library hosted within a Windows Service. The service end point is http://servername:9980/ApplicationServer/ServiceName.
When I run this service on local system and try to connect using my application, everything works fine.
The problem starts when I deploy this service on server system, none of my application can use this service, even the browser says page not found. Though, if I remove the specific port number from the endpoint all works well.
I have already opened all the ports in Windows Firewall including Client and Server. Also proper exceptions are made to the router firewall, still I am not able to host the service on specific port. I have even tried by switching firewall off on both client and server system.
Thank you in advance.

When you remove the specific port number it defaults to port 80.
So there is something that is blocking the other port.
Try using the Telnet command to check if the port is open (you may have to enable telnet)
As you have allready checked the firewalls, it could be urlscan or a network device.
Yesterday I created an Azure Virtual Machine using the simple Win2008r2 + SQL2008r2 image.
I have deployed a website to the VM via an RDP session.
I am able to browse the website locally (via RDP) using
"http://localhost"
I understand that I need to add an Azure endpoint for port 80 to enable me to browse to the site from an external machine.
I have configured the Windows Firewall on the Azure VM to allow traffic on Port 80 inbound and outbound.
Could anyone please advise what I've missed or what I can do to troubleshoot?
---Update-----
I have learned a little more this morning. The website that I'm trying to host on the VM is an installation of Interwoven Teamsite v7.3.x. When I looked in IIS I could see that the "Default Web Site" was stopped. Another website called "TeamSiteSitePubPreview" had been created but was only bound to port 81.
So, what was presenting the website I could see when I browsed to
http://localhost locally?
I ran netstat -ano and this showed me that PID 1604 what listening on port 80. I then ran Process Explorer which told me that PID 1604 was allocated to "Appache HTTP Server".
I know nothing about About Appache, can anyone tell me if there's some Apache config that will be preventing connections from outside of the local server?
For reference, I just tested this sequence and it gives you a website accessible over the Internet:
Create a new Windows Azure virtual machine with the Windows Server 2008 R2 SP1 image.
Add an endpoint on public port 80, private port 80.
While the endpoint is being created, start setting the server up.
Remote Desktop in.
Add the Web Server (IIS) role with default settings.
Test the connection. You should get a HTTP 200 OK status.
If you want to troubleshoot your server, start checking for errors in the event log. Check also the website bindings in IIS (Port 80, IP Address *).
Also consider the connection issue might be on the client (your) side. For instance, DNS caching. Try connecting from another machine with direct Internet connection (such as another cloud server) or from a service such as isup.me.
Additionally, if all you want is to host websites in IIS, the Web Sites service has a more streamlined experience.
You will need to create an endpoint on port 80 thru Windows Azure Management portal as well. This endpoint opens a port in the Windows Azure Load-balancer.
Navigate to your VM within the portal and create a new Endpoint under the Endpoints screen of VM configuration within Azure management portal.
I want to use my webservice on internet. I opened my port which is 4501 an I disabled firewall on modem and on windows. I can write my global ip and I can open modem control inteface. But I want to connect to iis which address is xx.xx.xx.xx:4501/Products.svc
It works on localhost (http://localhost:4501/Product.svc) But I cant connect to svc on internet ..
I dont know where is problem.
When I add my svc link addres as adding reference service I got this error
There was an error downloading 'http://xx.xx.xx.xx:4501/Products.svc'.
Unable to connect to the remote server
Hedef makine etkin olarak reddettiğinden bağlantı kurulamadı xx.xx.xx.xx:4501
Metadata contains a reference that cannot be resolved: 'http://xx.xx.xx.xx:4501/Products.svc'.
There was no endpoint listening at http://xx.xx.xx.xx:4501/Products.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.
Unable to connect to the remote server
Hedef makine etkin olarak reddettiğinden bağlantı kurulamadı xx.xx.xx.xx:4501
If the service is defined in the current solution, try building the solution and adding the service reference again.
And One point more,
If I start to IIS, wcf service doesnt work even in localhost. If I start it in Visual Studio (I mean asp.net development service works) it works..
IIS version is 7.5.7600 and I added application pool as Asp.net 4.0
Is there any specific reason you use port 4501 for HTTP in IIS?
Visual Studio 2010 WebDev WebServer (Cassini) uses random port number (4501 in your case) to simplify configuration. It assumes that port 80 can be occupied by its big brother IIS or any other software.
That is fine for development in local machine but there is no need to use the same port in production.
Default HTTP port is 80 and it is usually the most open open port in networks.
Use port 80 for HTTP traffic in IIS and your life will be much easier.
P.S. Did you try http://xx.xx.xx.xx/Products.svc? Port number is part of web service configuration and it is not copied when you move app to IIS. It is possible that IIS already uses default HTTP port.
I've built a WP7 application and a locally hosted (on my machine) WCF server in my solution. I have debugged it using the emulator and it works fine, however, when I debug via device and try to connect to the server I get an exception stating that the EndPointNotFound (I'm aware I haven't set up anything to catch this exception!). Is there anyway to connect to a localhost server via the device?
Many thanks

If you are trying to connect to your local machine from an actual device and it si not tethered, make sure that you are connected to the same local network.
What is the host name you are using to try and connect to the host machine? The emualtor will be able to resolve "localhost" to the host mahcien but your phone won't. You'll need to use the appropriate host name or IP address.
Download and install the Visual Studio SP1 tooling and host your WCF services using IIS Express. This webserver accepts incoming connections from other computers on your local network as long as there's a firewall exception to allow the connection.
You'll have to connect to the machine hosting the service through it's external IP. That cannot be localhost or 127.0.0.1 (it has to be something belonging to the same subnet).
Scott Hanselman had a presentation about the "MS Web Stack of Love" where he demos how to set all this up (using HTTPS even) and it goes into depth about how to configure the firewall and all that jazz. I recommend watching it, as he is also, a funny guy.
You can use a Wifi connection on WP7 and the local ip of your server in the config file to reference your WCF server ?
I'm using windows server 2008 & IIS 7.0 to deploy the my vb.net 3.5 application.
I'm successfully able to run the URL on my server.
Same URL having IP address & port number configured is not working on client system.
It is showing IE default error message as "page cannot display"
Thanks
A couple of things to do:
Try it in something other than IE - Or at the very least turn off IE "Friendly http error messages" as they obscure the real problem (Tools -> Internet Options -> Advanced)
Make sure the IIS website is bound to all IP Addresses not just 127.0.0.1 (localhost)
Make sure the windows firewall / other firewalls in use are configured to allow incoming traffic on port 80 through (assuming you're using port 80)
Check the event logs - If it's a coding problem, the error message is usually dumped in there
If the client system is on a different network, make sure that all your firewalls/routers are set up to allow the appropriate traffic through
Some more information which would help us:
Where (in network terms) is the client you mention? same network?
What happen if you use the full URL the client's using from a browser on the server?
When you say it works on your server, is that the VS development server? or the same server the client is using?
