NAME

       memlockd - daemon to lock files in memory with mlock

SYNOPSIS

       memlockd [ -c config-file ] [ -d ] [ -f ] [ -u user ]

DESCRIPTION

       This manual page documents briefly the memlockd command.

       It  is  used  to  lock  system  programs and config files in memory so that if a DOS attack is experienced then the chance of the sys-admin
       regaining control of the system in a reasonable amount of time (and therefore having a reasonable chance of discovering the  cause  of  the
       problem) is significantly increased.

OPTIONS

       The  -c	option is used to specify the fully-qualified path name to a config file that lists the names of files to lock, if the config file
       is not specified then it will default to /etc/memlockd.cfg. In any situation where a config file is used a directory can be  used  instead,
       for a directory every file ending in ".cfg" will be processed.

       The -d option specifies debugging mode, the program will not fork and will produce it's logging messages on stderr instead of via syslog.

       The -f option specifies foreground (non-daemon) mode, the program will not fork but will still log normally.

       The  -u	option	specifies  the name of a user to use for running ldd (for recursive operation).  Note that locking shared objects that are
       writable by non-root is not safe, but using a different UID will reduce the risk.

       The config file will contain a number of fully qualified names of files to lock in RAM.	When locking shared objects and ELF binaries it is
       possible  to  prefix the file name with a + character to indicate that memlockd should recursively lock all shared objects that the program
       requires and all shared objects that those objects require. When a file not found error doesn't matter (EG you want a single config file to
       have  the  file	names for multiple architectures or systems) you can prefix the file name with a ?  character, in that case errors such as
       EPERM will still be logged.

       If a line in the config file starts with a % character it will be taken as the name of a config file or directory  to  process.	 Currently
       only one level of recursion is accepted.

NAME

       clfdomainsplit - split Common-Log Format web logs based on domain name

SYNOPSIS

       clfdomainsplit [--help] [-i input] [-d defaultfile] [-c cfg-file] [-o directory]

DESCRIPTION

       The clfdomainsplit program will split up large CLF format web logs based on domain name.  This is for creating separate log analysis passes
       for each domain hosted on your server.

OVERVIEW

       The  input parameter specifies the file to read (default is standard input).

       The  defaultfile parameter specifies where data goes if it doesn't have a domain (either it has an IP address for the server or it  doesn't
       have the server-name - the URL is relative to the root of the web server only).	The default will be to print them on standard error.

       The  cfg-file  parameter is for specifying the rules for determining what is a different domain name.  For example www.coker.com.au belongs
       in the same file as coker.com.au and abc.coker.com.au because domain names ending in .au have three major  components.	The  domain  names
       www.workbenelux.nl and workbenelux.nl belong in the same file because domain names ending in .nl have two major components (as do .com, and
       .gov), wheras anything ending in .va belongs to the same organization.  The rules are of the form number:pattern which lists the number	of
       domain parts which are significant (2 for .com and for a simple string comparison, the default will be:

       2:com

       2:nl

       3:au

       3:uk

       If  no  config file is specified then it will look for /etc/clfdomainsplit.cfg.	Of course comments start with #.  Also note that the first
       match will be used!

       The directory parameter is to specify the location for the files to be created (default is the current directory).  I  recommend  that  you
       use a directory for this and nothing else as you never know how many files may be created!

EXIT STATUS

       0 No errors

       1 Bad parameters
