SYSLOG-NG messages
Hi,

Let me try to explain what the script (pasted below) actually does.

I have syslog-ng installed on a server. It logs all messages (example firewall logs) from different clients. But the log messages are stored in a database.

When i launch the script manually (via putty), it works fine, but eventually when i quit putty, the script stops.

So basically messages are sent to a pipe file namely mssql.syslog-ng.pipe, then messages from there are written to database. As you can see its in a while loop, so it waits permanently for messages. Thats the way it should be. It should run in the background actually. My problem is i dont know how to make it start whenever the server starts and it should run in the background.

What i meant by it hangs in my previous post was it was waiting messages, so it hangs there waiting and the server is not loaded completely. Its not like you are starting oracle on startup and it gets started and the server proceeds with other processes.

I dont know if its clear enough now, but im still trying to find out a solution.

Thanks

Code:
#!/bin/sh
#
# File: syslogng-mssql-pipe.sh
#
# Take input from a FIFO and run execute it as a query for
# a sqlserver database.
#


if [ -e /tmp/mssql.syslog-ng.pipe ]; then
       while [ -e /tmp/mssql.syslog-ng.pipe ]
                do
                       echo "INN"
                       isql -v MSTEST "sa" "password" </tmp/mssql.syslog-ng.pipe
                done
else
        mkfifo /tmp/mssql.syslog-ng.pipe
fi

shcomp

SHCOMP(1)						    User Environment Utilities							 SHCOMP(1)

NAME

       shcomp - compile a ksh93 shell script

SYNOPSIS

       shcomp [ options ] [infile] [outfile]]

ORIGIN OF THIS MAN PAGE

       This man page was written by Christophe Martin <Schplurtz@free.fr> for the Debian GNU/Linux system. It is based on "shcomp --man" output.

DESCRIPTION

       Unless  -D  is  specified,  shcomp takes a shell script, infile, and creates a binary format file, outfile, that ksh93 can read and execute
       with the same effect as the original script.

       Since aliases are processed as the script is read, alias definitions whose value requires variable expansion will not work correctly.

       If -D is specified, all double quoted strings that are preceded by $ are output. These are the messages	that  need  to	be  translated	to
       locale specific versions for internationalization.

       If  outfile is omitted, then the results will be written to standard output.  If infile is also omitted, the shell script will be read from
       standard input.

OPTIONS

       -D, --dictionary
	      Generate a list of strings that need to be placed in a message catalog for internationalization.

       -n, --noexec
	      Displays warning messages for obsolete or non-conforming constructs.

       -v, --verbose
	      Displays input from infile onto standard error as it reads it.

       --man  Displays this man page on standard error and exits.

       --help Shows a short help message and exits.

EXIT STATUS

       0      Successful completion.

       >0     An error occurred.

DEBIAN WARNING

       On a Debian GNU/Linux system, more than one package may provide ksh. the output of shcomp can only be used by ksh93.  Any other ksh will be
       unable to run the compiled script.

EXAMPLE

       ( echo '#! /bin/ksh93' ; shcomp myscript ) > myscript.bin &&
       chmod 755 myscript.bin
       ./myscript.bin
