Can one process have more than one socket?
yes , a process could have more that one socket (combination of ip address and port address) but at a particular instance of time it can be only one..
How many sockets can an application have?
For most socket interfaces, the maximum number of sockets allowed per each connection between an application and the TCP/IP sockets interface is 65535.
Can processes share sockets?
Sockets can be shared among threads in a given process without using the WSADuplicateSocket function because a socket descriptor is valid in all threads of a process. A process can call closesocket on a duplicated socket and the descriptor will become deallocated.
How many sockets can be opened at once?
65535
For most socket interfaces, the maximum number of sockets allowed per each connection between an application and the TCP/IP sockets interface is 65535.
Can two processes use the same port?
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 can be made to a single socket?
On the TCP level the tuple (source ip, source port, destination ip, destination port) must be unique for each simultaneous connection. That means a single client cannot open more than 65535 simultaneous connections to a single server. But a server can (theoretically) serve 65535 simultaneous connections per client.
Can two processes read on same socket?
1 Answer. Two processes cannot bind (and listen) to the same unix socket.
How many processes can connect to a socket?
10 Answers. You can share a socket between two (or more) processes in Linux and even Windows.
A connected socket is assigned to a new (dedicated) port, so it means that the number of concurrent connections is limited by the number of ports, unless multiple sockets can share the same port.
How many requests can a port handle?
4 Answers. A port doesn’t handle requests, it receives packets. Depending on the implementation of the server this packets may be handled by one or more processes / threads, so this is unlimited theoretically.
Is there a way for multiple processes to share a socket?
Is there a way for multiple processes to share a listening socket? In socket programming, you create a listening socket and then for each client that connects, you get a normal stream socket that you can use to handle the client’s request. The OS manages the queue of incoming connections behind the scenes.
Is it possible to have multiple TCP sockets on the same port?
It is possible to have multiple TCP sockets listen on the same port number. There is a caveat to this though, each socket on the same server listening on the same port number must be associated with a different IP address. For example]
What happens when a socket is accepted?
The accepted socket is passed to one of your available worker tasks, and the main task goes back to listening. Under Windows (and Linux) it is possible for one process to open a socket and then pass that socket to another process such that that second process can also then use that socket (and pass it on in turn, should it wish to do so).
Can a process have more than one file per process?
In general yes, mostly in the same way a process can have multiple files opened simultaneously. On UNIX and UNIX-like systems the limit is basically given by the limits on the maximum number of opened file descriptors per process and the availability of system resources. 8 clever moves when you have $1,000 in the bank.
