I've wrote a self-hosted servicestack server and a client, both desktop applications.
In my very basic PING test service I'm trying to retrieve the IP of the client.
Server is on 192.168.0.87:82, client I tried on the same computer and on another computer, but RemoteIp and UserHostAddress always return 192.168.0.87:82. XRealIp is null.
I also tried base.Request.RemoteIp, but still is 192.168.0.87:82.
What am I doing wrong?
public RespPing Any(ReqPing request)
{
string IP = base.RequestContext.Get<IHttpRequest>().RemoteIp;
string MAC = request.iTransactionInfo.MAC;
Log(MAC,IP, base.RequestContext.Get<IHttpRequest>().RemoteIp + base.RequestContext.Get<IHttpRequest>().XRealIp + base.RequestContext.Get<IHttpRequest>().UserHostAddress);
RespPing response = new RespPing { Result = "PONG" };
return response;
}
Thanks!
Made it with:
HttpListenerRequest iHttpListenerRequest = (HttpListenerRequest)base.RequestContext.Get<IHttpRequest>().OriginalRequest;
string IP = iHttpListenerRequest.RemoteEndPoint.ToString().Split(':')[0];
Request.RemoteIP kept giving me the server address.
ServiceStack.4.0.38
string IP = base.Request.RemoteIp;
fwiw I had to do something just a little bit different:
HttpListenerRequest iHttpListenerRequest = (HttpListenerRequest)base.RequestContext.Get<IHttpRequest>().OriginalRequest;
string ip = iHttpListenerRequest.RemoteEndPoint.Address.ToString();

I have a service hosted on Google Cloud Run. The service uses socket io whenever the service is up and running.
When a socket client connects to the service I have the following function that gets the ip address of the connected client from the socket as shown below and then I am hitting this GeoPlugin Link with the retrieved IP
async getSocketIP(socket) {
let { headers, address } = socket.handshake;
let { origin } = headers;
let ip = headers['x-forwarded-for'];
let userAgent = headers['user-agent'];
try {
let locationPointUrl = `http://www.geoplugin.net/json.gp?ip=${ip}`;
let { data: location } = await axios.get(locationPointUrl);
} catch (e) {
console.log(`Error get client online IP on Socket IO`);
}
}
Unfortunately, irrespective of the User's Location the IP always resolves to US.
I have a custom domain mapped to the cloud run service via Domain Mapping.
What could be the reason the IP of the Client is always US IP?
Please note that this same service when hosted on Heroku gets the correct IP address of the connected client.
So, I'm very certain that it has something to do with Cloud Run.
All my services on Cloud Run are on US-CENTRAL1
For anyone who may experience something like this in the future.
We had Cloudflare sitting in front of Cloud Run.
So, to get the correct Client's IP address all we had to do was retrieve it from cf-connecting-ip header instead of x-forwarded-for.
So, the modified and working code now becomes:
async getSocketIP(socket) {
let { headers, address } = socket.handshake;
let { origin } = headers;
let ip = headers['cf-connecting-ip'] ?? headers['x-forwarded-for']; //Notice the difference
let userAgent = headers['user-agent'];
try {
let locationPointUrl = `http://www.geoplugin.net/json.gp?ip=${ip}`;
let { data: location } = await axios.get(locationPointUrl);
} catch (e) {
console.log(`Error get client online IP on Socket IO`);
}
}
There is a mechanism in node to get the remote IP by calling req.connection.remoteAddress.
I tried the below code to get the remote IP of the client but the result is undefined.
var ipAddr = req.headers["x-forwarded-for"];
if (ipAddr){
var list = ipAddr.split(",");
ipAddr = list[list.length-1];
} else {
ipAddr = req.connection.remoteAddress;
}
console.log("req.connection.remoteAddress:" + ipAddr);
Does anyone know if I can get the remoteIP in Parse.com cloud code?
Tried the following as per one suggestion;
static void Main()
{
string url = "http://localhost:8080/";
StartOptions options = new StartOptions();
options.Urls.Add("http://localhost:8080");
options.Urls.Add("http://127.0.0.1:8080");
options.Urls.Add(string.Format("http://{0}:8080", Environment.MachineName));
using (WebApp.Start<Startup>(options))
{
HttpClient client = new HttpClient();
var response = client.GetAsync(url + "api/Values").Result;
Console.WriteLine(response);
Console.WriteLine(response.Content.ReadAsStringAsync().Result);
Console.ReadLine();
}
}
Can connect with local browser, but remote machines get 'webpage is not available'.
Set reservation with 'add urlacl url=http://*:8080/ user=EVERYONE'
Port 8080 is open, tried many other ports with same results.
tried suggestion below, same result;
var options = new StartOptions("http://*:8080")
{
ServerFactory = "Microsoft.Owin.Host.HttpListener"
};
Nothing is working remotely, only locally - is there anything else I can try?
I am trying to develop a Video Client/functionality that captures video using webcam and transfers to other servent (server-client) somewhere on the internet. I am using UDPCLient Class to do that.
I want my application to be able to listen and tarnsmit video captured from webcam. The capturing, transmission and receiving works fine when i do that on local network.
But when i test the application from behind router (across two differnt networks/internet) after forwarding respective ports, the internet connectivity is lost on both routers (They hang up or something) and i need to restart the routers or switch to an alternate connection. The configuration is as follows:
Servent 1 <--> Router1 <--> Internet Connection#01
Servent 02 <---> Router2 <---> Internet Connection#02
Both connections are on separate DSL Line. One of the routers is ZTE brand and the other is of Netgear.
Code for listenning/transmission is as follows:
private void StartSockets()
{
//For testing across internet i use IPAddress obtained via different function
var IPAddress = getMyIpAddress();
this.udpSender = new UdpClient(IpAddress, 4000);
this.udpListener = new UdpClient(4000);
}
private IPAddress getMyIpAddress()
{
IPAddress localIP ;//= AddressAr[0];
localIP = IPAddress.Parse(GetPublicIP());
return localIP;
}
public string GetPublicIP()
{
String direction = "";
WebRequest request = WebRequest.Create("http://checkip.dyndns.org/");
using (WebResponse response = request.GetResponse())
{
using (StreamReader stream = new StreamReader(response.GetResponseStream()))
{
direction = stream.ReadToEnd();
}
}
//Search for the ip in the html
int first = direction.IndexOf("Address: ") + 9;
int last = direction.LastIndexOf("</body>");
direction = direction.Substring(first, last - first);
return direction;
}
Code for receiving response is as follows:
private void ReceiveData()
{
//For testing across internet i use IPAddress obtained via different function
var IPAddress = getMyIpAddress();
IPEndPoint ep = new IPEndPoint(IPAddress, myPort);
try
{
byte[] receiveBytes = this.udpListener.Receive(ref ep);
this.OnReadImage(new ImageEventArgs(this.ByteToImage(receiveBytes)));
}
catch (Exception)
{
}
}
If i test on local network , i use DNSHostname to get ip address (private ip addresses) and video works fine on local network. That does not work over internet so i switch to live Ip Address and thus i use the method of getPublicIpAddress().
I know there is something seriously wrong with my approach? What would be right approach?
Should i switch to TCP Listenner? I intend to have multiple receiver of same video in future. So would that affect?
Can UDP clients cause routers to crash, hang up and restart? How can i avoid that?
Lastly, if were to avoid port-forwarding what would be the best strategy?
Please help.
Thanks

I am creating a J2ME real time streaming audio player with RTP and through SIP connection. Also I am new for these things. I want to take look deeply those things. If any one know a good working sample code demonstrating an audio player streaming with RTP (That means how to send a REGISTER message to the server through SIP to get registered and send an INVITE message and get the response & play). Please let me know, highly appreciated.
Also I looked here

My server port is 6060
ip 111.111.111.1
id is myid password 123
Have I used the code correctly? If I am wrong, please make me correct.
public void doRegister(String username, String password, String realm) {
SipClientConnection scc = null;
SipConnectionNotifier scn = null;
String contact = null;
try {
scn = (SipConnectionNotifier) Connector.open("sip:5080");
contact = new String("sip:myid:123#"+scn.getLocalAddress()+":"+scn.getLocalPort());
scc = (SipClientConnection) Connector.open("sip:111.111.111.1+"transport=tcp") ;
scc.initRequest("REGISTER", scn);
scc.setHeader("From", "sip:myid:123#"+scn.getLocalAddress()+":5080");
scc.setHeader("To", "sip:myid:123#111.111.111.1");
scc.setHeader("Contact", contact);
scc.send();
boolean handled = false;
int scode = 0;
while(!handled) {
SipHeader sh;
scc.receive(30000);
scode = scc.getStatusCode();
switch(scode){
case 401:
sh = new SipHeader("WWW-Authenticate",
scc.getHeader("WWW-Authenticate"));
realm = sh.getParameter("realm");
scc.setCredentials(username, password, realm);
break;
case 407:
sh = new SipHeader("Proxy-Authenticate",
scc.getHeader("Proxy-Authenticate"));
realm = sh.getParameter("realm");
scc.setCredentials(username, password, realm);
break;
case 200:
handled = true;
break;
default:
handled = true;
}
}
scc.close();
} catch(Exception ex) {
// handle Exceptions
}
}
I got a respond with 180 Rigging message. Also let me know what is realm here. scc.setCredentials(username, password, realm);
As you see here in example 1 - you realize that when you make a fresh Reqeust to server, where as server expects authentication it first sends 401. By seeing this the client can then either search for a password or ask the user. When server sends the 401 response code, it specifies which security domain is applicable for the given requests. This is already what you have got in your code :
realm = sh.getParameter("realm");
Once, failed, you need to send() the request again with credentials here. I guess the setCredentials() function is only setting these parameters inside the scc object and they will be applied when send() is called again.
