title: How to change maximum no of file descriptors open in linux?
body: <p>When i try to open max number of simultaneous socket connection using epoll , it stucks on 1024 .After this it give "Too many files open" error . I know that this is not the limit .I tried to change nofile parameter value in  /etc/security/limits.conf but i only have read-only permissions there.Is there any method to increase the number of file descriptors opened simultaneously?</p>
