Can multiple threads listening on same port?

Can multiple threads listening on same port?

Multiple servers (processes or threads) can bind to the same port if they each set the option as follows: With TCP sockets, it allows multiple listening sockets—normally each in a different thread—to be bound to the same port. Each thread can then accept incoming connections on the port by calling accept().

What is socket reuse?

The SO_REUSEADDR socket option allows a socket to forcibly bind to a port in use by another socket. For example, if all of the sockets on the same port provide TCP service, any incoming TCP connection requests over the port cannot be guaranteed to be handled by the correct socket — the behavior is non-deterministic.

Can I reuse Bitcoin address?

Address reuse is when a single bitcoin address is used repeatedly for different transactions. Ideally, every bitcoin address is only used once. Reusing addresses can have negative implications such as diminished privacy and diminished security.

Can 2 services listen on same port?

For TCP, no. You can only have one application listening on the same port at one time. Now if you had 2 network cards, you could have one application listen on the first IP and the second one on the second IP using the same port number. For UDP (Multicasts), multiple applications can subscribe to the same port.

Can two services use the same port?

It is possible. You just have to bind on the right IP address/interface each service using the same port. Ports (be them UDP or TCP) have their own pool per IP address. You can listen on the same port if you change: IP address or protocol (UDP or TCP).

What is Tcp_nodelay?

The TCP_NODELAY socket option allows your network to bypass Nagle Delays by disabling Nagle’s algorithm, and sending the data as soon as it’s available. Enabling TCP_NODELAY forces a socket to send the data in its buffer, whatever the packet size. To disable Delayed ACKs, use the TCP_QUICKACK socket option.

What is So_broadcast?

Socket semantics require that an application set the SO_BROADCAST option on before attempting to send a datagram to a base or broadcast address. This protects the application from accidentally sending a datagram to many systems.
