How can I increase the number of sockets and files that I can simultaneously have open under Linux?
Nathan Meyers Linux 2.2.x kernels allow control of the maximum number of open files through the /proc/sys/fs/file-max pseudo-file. Read that file to see the current limits; write a new value to it to change the limit. For example:
cat /proc/sys/fs/file-max echo 16384 >/proc/sys/fs/file-max
You may also find it useful to manipulate the kernel inode limit. This is controlled, using the same techniques, through the /proc/sys/fs/inode-max pseudo-file.
