How do I view the listen backlog of a TCP socket?
Issue
- How do I view the size of the backlog of a tcp socket in "LISTEN" state?
- How can I see the current and maximum count of handshaken TCP connections waiting in the
listen()
backlog of a socket waiting to haveaccept()
called on them? - How can I tell if increasing
net.core.somaxconn
andlisten(int sockfd, int backlog);
has worked?
