Common questions

Can I use the same port number for server and client?

Can I use the same port number for server and client?

The client and server don’t need to use the same port. As you pointed out, a port can only be allocated to a single process at a time on a machine. To be more correct, a port and IP address pair is the allocation unit. So if your machine has two addresses or more one can bind the port to different processes per IP.

How do I run a client and server on the same port?

3 Answers. In order to run both client and server applications on the same host you should bind your server socket to localhost (you can actually write “localhost” it’s a preserved word or 127.0. 0.1 ) and address it from the client as well. Localhost allways refers to the computer you work on.

Can you have multiple TCP connections on same port?

Multiple connections on the same server can share the same server-side IP/Port pair as long as they are associated with different client-side IP/Port pairs, and the server would be able to handle as many clients as available system resources allow it to.

What is TCP client in C#?

The TcpClient class provides simple methods for connecting, sending, and receiving stream data over a network in synchronous blocking mode. In order for TcpClient to connect and exchange data, a TcpListener or Socket created with the TCP ProtocolType must be listening for incoming connection requests.

How do I connect to a TCP port?

If you want to test a TCP service on your local computer, use the IP address 127.0….For Windows 9x/Me:

  1. Click Start, and then click Run.
  2. Type telnet and click OK.
  3. Click Connect, then click Remote System.
  4. Enter the hostname/IP and port number in the appropriate fields.
  5. Click Connect.

Do clients have ports?

TCP/IP works with the client operating system to maintain a table of client-side ports. Client-side ports start at port 49,152 and increment up to 65,535. If the system uses all the ports between 49,152 and 65,535 before being rebooted, it’ll start over at 49,152.

Can we use same port for 2 listeners?

Yes. Multiple listening TCP sockets, all bound to the same port, can co-exist, provided they are all bound to different local IP addresses. Clients can connect to whichever one they need to.

How many connections does a port allow?

Ports are 16-bit numbers, therefore the maximum number of connections any given client can have to any given host port is 64K. However, multiple clients can each have up to 64K connections to some server’s port, and if the server has multiple ports or either is multi-homed then you can multiply that further.

What is the difference between a client and a server computer?

Difference between client and server. • Client is a smaller computer through which the information or application stored on the server is accessed by the user whereas server is a powerful computer that stores the data files and applications. • In some cases, the client may utilize the greater processing power of the server machine.

What is a TCP IP server?

in: TCP/IP. Overview. TCP/IP (an acronym for Transmission Control Protocol/Internet Protocol) is a software-implemented protocol for connecting different networks to each other. The TCP component of the suite controls the disassembly and reassembly of data packets sent from a computer server, where the data resides.

What is TCP in Microsoft?

Microsoft TCP/IP offers the Windows Sockets interface, which is ideal for developing client/server applications that can run on Windows Sockets–compliant stacks from other vendors. A method of gaining access to the Internet. The Internet consists of thousands of networks worldwide, connecting research facilities, universities,…
