Simple Server Question

I'm writing a server which accepts connections with the following line:

TcpClient client = listener.AcceptTcpClient();

Next, I'd like to be to determine the client's IP address.

How can I do this? No relevant property/method in TcpClient exists.

Try
Socket s = tcpClient.Client;
IPEndPoint ep = s.RemoteEndPoint as IPEndPoint;
IPAddress address = ep.Address

Hi Jared,

'Client' doesn't appear to be a property of 'TcpClient'. What is
'tcpClient' an instance of in the above code?

Thanks.

Sorry. Didn't read the documentation close enough. Apparently the
TcpClient.Client property is protected. You can try sub classing TcpClient
to get to the Client property. Outside of reflection I don't see another
way to get to that property.

Ah... it seems a real nuisance that it's protected.

So I guess it isn't possible to determine the client's IP address when
using TcpListener.AcceptTcpClient(), then...

client.RemoteEndPoint..Address.ToString() should give it to you.

Hi,

'TcpClient' doesn't have a property called 'RemoteEndPoint'.

BTW, I'm using 'TcpListener.AcceptSocket()' instead of
'TcpListener.AcceptTcpClient()' now, so my question no longer needs an
answer.

Thanks for the replies.

Indy exposes all this for you. :)

Hi Chad,

Yeah, Indy was the first thing that crossed my mind when I started this
project, but I decided to try using the lower-level .NET sockets for the
learning experience (my HTTP knowledge was a bit stale and re-inventing
the wheel is a good way for me to learn :-).

Cheers.
