php, perl..?
install lighthttp with php support, learn some php and you can do 'anything'.
take a look at http://phpshell.sourceforge.net/ for instance.

Stargrove1,

I'm sure that lots of people have already added lighttps or some other web server and added what they wanted, but the problem with your request is that there is no generic need for "all the functions", whatever that means to you.  And it would certainly mean different things to different people, and there is an endless amount of "functions" that could be added.

Of course to even start a task like this you need two things.  One is a clear definition of what you want.  Clearly a "function" to list all the /Backup/* files is a different function then mount/unmount a given USB drive.  The second part is just the knowledge to write the code (and yes it is code/software) to tell what to put on the web page and what to do when someone enters something, and clicks a button.  BTW there is not one language when you are talking about web programing, I prefer Perl, but there is PHP, and plain old HTML, and a ton of others.  And knowing them is needed to both get the web page up, and also to call the operating system to do things like mount a drive.

Personally I really actually prefer not to do it in web form.  Much easier to right a script in shell or Perl that runs in the background that say waits for a file to be created in a directory /mnt/HD_a2/startShutdown called "start", and when it sees it start a shutdown.  And then just have a script run from my toolbar (PowerPro) on my Windows machine that creates that file when I click on a button.  This is exactly what really happens on my system (I have another directory/file for starting a backup, and combine the two for a backup before shutting down for removal of a drive for offline storage).

Well the start of this of course how to get the shell script running in the background at start up.  For that and other things I have Fonz's fun_plug (ffp) installed.  You could also just create your own fun_plug shell script on the first hard drive on the DNS-323, but Fonz's ffp is much more useful to expand on.
http://dns323.kood.org/howto:ffp

With ffp installed there are two directories of interest for the ffp/start and ffp/share. I put in a file called backupCmd.sh in the ffp/start directory, and logged into the DNS-323 and made sure is has execute permissions so that it will run at start up (log in using telnet or ssh):
chmod +x /ffp/start/backupCmd.sh

backupCmd.sh contains:
------------------------------------------------------------------------------------
#!/ffp/bin/sh

# PROVIDES: backupCmd
# BEFORE: LOGIN

. /ffp/etc/ffp.subr

name="backupCmd"
start_cmd="backupCmd_start"
stop_cmd="backupCmd_stop"
required_files="/ffp/share/NAS-BackupCmd/NAS-BackupCmd.sh"

backupCmd_start()
{
   echo "Setting up $name..."
   /ffp/share/NAS-BackupCmd/NAS-BackupCmd.sh &
}

backupCmd_stop()
{
   /ffp/bin/killall NAS-BackupCmd.sh
}
run_rc_command "$1"
____________________________________________
(Don't include the ------------------------ lines, and you can call the file and all the entries inside with backupCmd anything you like.

This just runs/stops the NAS-BackupCmd.sh script in the background (& after command is "in background") that is in the /ffp/share/NAS-BackupCmd (just a directory in the ffp/share directory I created to keep my stuff separate.  If I included the real NAS-BackupCmd it would just confuse people because it is highly tailored to my backups, but what I have posted below will shutdown the DNS-323 when a file "startShutdown.txt" is created on the first drive in the DNS-323 (I actually run from a USB drive so in the real script the paths are different).
____________________

#! /bin/sh

FLAG_SHUTDOWN_FILE="/mnt/HD_a2/startShutdown.txt"

while [ 1 ]; do
   if [ -f $FLAG_SHUTDOWN_FILE ]; then
      echo "Signaled for shutdown"
      rm $FLAG_SHUTDOWN_FILE
      shutdown
      exit 0
   fi
   sleep 5
done
_____________________________

You could have many if statements with many different files, and run basically any command the DNS-323 knows.
You could even get fancy and run commands that check the contents of the file for commands, but a simple check if the file exists or not is easier.

The echo command should show up in the ffp.log file.  If you want to print another file just redirect its output to another file like:
LOG=/mnt/HD_a2/myLog.txt
echo "Log this" > $LOG # The single > creates the log file (and deletes an old version if it exists)
ls /ffp >> $LOG # The >> appends to an existing file, or creates it if it doesn't exist.
mount >> $LOG 2>&1 # The 2>&1 makes error message go to the log too.
df >> $LOG

Log into the DNS-323 and make sure the script has has execute permission:
ls -l /ffp/share/NAS-BackupCmd/NAS-BackupCmd.sh
(looks like: -rwxrwxrwx    1 Chris    Users        6498 Aug 17 23:59 NAS-BackupCmd.sh) (the x's are execute permissions, (read/write/execute) for owner, group, other).
chmod +x /ffp/share/NAS-BackupCmd/NAS-BackupCmd.sh (if not right)

Once you reboot the DNS-323 the NAS-BackupCmd.sh should be running you can check that by looking at the ffp.log, and by logging into the DNS-323 and running either the "ps" or the "top" command, and you should see NAS-BackupCmd.sh as one of the running processes.

__________
Please note one thing,  as written the script is going to look for the file every 5 seconds on your hard drive so that hard drive is not going to sleep.  This is not a problem for me, because I run ffp and have the "flag file" on a USB Flash drive that I don't care if it doesn't sleep, but this could certainly be an issue for you.  This is a case where it might be a better idea to install another web server like lighttpd and make your own commands, but running almost anything off of the hard drive instead of an USB flash drive is going to not allow your hard drive to sleep.

Thank you again for the informations. Unfortunately I still want the spin down function of the hds. Perhaps there is a small chance that the other post leads to a solution for me.
