Can you post output of
You should perhaps increase the value of max open files kernel parameter.
Also remember that those parameters can be setuped per user in limits.conf
I've been googling for a while now, trying to forward port 3000 to port 80....
In the past I used to DLink router to forward port 3000 to 80. I recently finished (well, is it ever done anyhow?) setting up my linux box and got it acting as a router.
I want to continue to run Apache on port 80... (1 Reply)
Hi,

So changing the port i listen to to one greater than 1023 isn't... (1 Reply)

Hi
I want to set up port forwarding from one network to another network. I already have this configured on the Linux box using iptables.

ulimit
ULIMIT(3) BSD Library Functions Manual ULIMIT(3)NAME
ulimit -- get and set process limits
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <ulimit.h>
long int
ulimit(int cmd, ...);
DESCRIPTION
The ulimit() function provides a method to query or alter resource limits of the calling process. The method to be performed is specified by
the cmd argument; possible values are:
UL_GETFSIZE Return the soft file size limit of the process. The value returned is in units of 512-byte blocks. If the result cannot be
represented in an object of type long int, the result is unspecified.
UL_SETFSIZE Set the hard and soft file size limits of the process to the value of the second argument passed, which is in units of
512-byte blocks, and which is expected to be of type long int. The new file size limit of the process is returned. Any
process may decrease the limit, but raising it is only permitted if the caller is the super-user.
If successful, the ulimit() function will not change the setting of errno.
RETURN VALUES
If successful, the ulimit() function returns the value of the requested limit. Otherwise, it returns -1, sets errno to indicate an error,
and the limit is not changed. Therefore, to detect an error condition applications should set errno to 0, call ulimit(), and check if -1 is
returned and errno is non-zero.
ERRORS
The ulimit() function will fail if:
[EINVAL] The cmd argument is not valid.
[EPERM] It was attempted to increase a limit, and the caller is not the super-user.
SEE ALSO getrlimit(2), setrlimit(2)STANDARDS
The ulimit() function conforms to X/Open System Interfaces and Headers Issue 5 (``XSH5'') and IEEE Std 1003.1-2001 (``POSIX.1''). It was
marked as obsolete in the IEEE Std 1003.1-2008 (``POSIX.1'') revision, which recommended the use of getrlimit(2) and setrlimit(2) instead,
noting that because ulimit() uses the type long rather than rlim_t, it may not be sufficient for file sizes on many current systems.
