Hello serial69,
here is an example to fix this problem in CSharp:

The long form with debug:

Code:

string localDnsName =  Dns.GetHostName();
Console.WriteLine("Dns name : " + localDnsName );

IPHostEntry localHost = Dns.Resolve( localDnsName );
Console.WriteLine("Host name : " + localHost.HostName);

IPAddress[] localAddresses = localHost.AddressList;
Console.WriteLine("IP address List : ");
foreach( IPAddress ip in localAddresses )    
    Console.WriteLine( ip );
//alternativ:
//for(int i=0; i < localAddresses.Length; i++)
//    Console.WriteLine( localAddresses[i] );

// listen on port  4567
TcpListener tcpServer = null;
if( localAddresses.Length > 0 )
    tcpServer = new TcpListener( localAddresses[0], 4567 );

Or the short form without debug:

Code:

IPHostEntry localHost = Dns.Resolve( Dns.GetHostName() );
TcpListener tcpServer 
    = new TcpListener( localHost.AddressList[0], 4567 );

I hope that helps you, else see:

Hi,

To listen on ALL ip addresses (page 820 of VB.NET 2003):

Replace the line:
_listener = New TcpListener(Form1.ServicePort)

with:
_listener = New TcpListener(Net.IPAddress.Parse("0.0.0.0"), Form1.ServicePort)

Hope this helps :D,

Ben
