Clarification - Setting socket options at the same time when socket is listening
I need clarification on whether it is okay to set socket options on a listening socket
simultaneously when it is being used in an accept() call?
Following is the scenario:-
-- Task 1 - is executing in a loop - polling a listen socket, lets call it 'fd', (whose file descriptor is global) for an incoming connection request with select() and then executing accept(fd,...) when a connection request arrives.
-- Task 2 - is a task that receives config commands from console and manipulates internal structures in response to them. As part of a particular command, it sets an option on the same listen socket using setsockopt(fd,....)
The option must be set on the listen socket fd ONLY when intimated to do so via a console command.
Can someone please clarify if it is okay to perform setsockopt on a socket when the same is being used in a simultaneous accept() call in another task?

I basically want to know if SO_KEEPALIVE is enabled on a socket to know if the tcp_keepalive_abort_interval parameter will be used by that connection.
Was I clear enough? :confused:

Is there a Linux tunable to reduce the amount of time a socket waits before considering the remote side dead?
Its the same senario when you try to telnet to a dead machine, telnet sits and waits for ~30seconds, before the socket timer expires and cancels the request. (5 Replies)
